February
It is the first. I will shave!
I have shaved, but not very thoroughly. My moustache is now catching up with my beard though, so that is good news.
@JSlayerUK you have an android phone? wow, is it very good? I want to replace my n95 in a while but the g1 didn't look too mind-blowing.
snow!
We have the ingredients. Club sandwich time.
club sandwich ruined by weirdo bread.
just destroyed my mouth with an insane madras
tesco value cookies are a bum deal
Writing corny narrative for the game.
I have really slow reactions. Apparently the mean is 180-200ms, I consistently get around 440ms.
making pleasing progress on the game
@JSlayerUK Not just you. I tend to think I'm pretty fantastic, and I find writing cover letters impossible too.
Scone success! Clotted cream and everything.
Walktall just sent me a sale email with just size 13 shoes in it. Clever thinking!
no sir, I don't think I am a fan of sweetmeal biscuits
I don't know when it became OK to put chorizo on a hamburger, but I certainly wasn't consulted
interactive timeline snow map! yes! http://is.gd/iwTS
worked out how to do the theorem prover, will code tomorrow.
well, technically it's tomorrow. couldn't sleep, and got it working first time!
flat out do not understand my grammar parser. Might have to rewrite it.
turns out my logic thing wasn't as good as I thought. I've rewritten it the proper way, and the grammar thing is still getting on my nerves.
@JSlayerUK practically every little village in northumberland has a shop with one in the window. They reappeared a few years ago, dunno why.
watch Ketch! and Hiro-Pon Get It On on iplayer. Very funny but so arty.
vanishingly little progress made today, still getting the new grammar thing to do everything it needs to
finished new grammar system!
today I had a serrano, monterey jack and mayo sub. It was ok!
is some kind of programming god
http://www.txbeef.org - tex-mex recipes galore!
@aperfect was that on mac or pc?
"the joy of sex education" arrived today, rated 18. Progress!
staring at the Koala Survivor, so happy
@JSlayerUK marcus brigstocke had a go with the late edition but he didn't have anywhere enough good writers to make it work.
loooves the snow
@brittneybean wow! my wongo-tall-guy chair cost about £400, but uni disability support paid for it. I'll look on ebay when it breaks, thanks
finished marking. 3 1/4 hours! Some students' handwriting is like a child's scrawl.
@kenfodder shouldn't you be using diary instead of twitter?
the exciting bossa nova samba rhythms are still my favourite albums
it is in fact The Bossa Nova: Exciting Jazz Samba Rhythms
got to write a new font system because hardware-filtered scaling looks awful
9pm and I still haven't made my dinner
@aperfect making a hilarious attempt at meatballs following the old fashioned cookbook
meatballs would've been nice if I'd had a real tomato sauce. At least they were cooked.
New font thing works! Still a programming deity.
@aperfect you and alisha's attic, sheesh
working on new fencing bit, dude is already comical
bad mood = dominos
cutting the vitruvian man into bits for a skining experiment
sorting out my eejit flatmates' energy bill affairs
@kenfodder heh, you mean there isn't someone at twitter judging every picture?
@aperfect that can not be good for you
so much traffic. What's the deal,geordies?
just realised I haven't looked at b3ta in weeks!
"Kangaroos are not terrifying. This is why so many tourists are mauled by them."
@brittneybean just say 'BFF' a lot. They love it.
I recant all opinions I have held of PG Wodehouse
trying to decide how to draw fencing dudes
I'm sure radio 4's late night schedule is designed to instil existential doubt
new series of one! radio 4! listen!
I now own three different sets of compasses. I might have a problem.
@aperfect wow, where?
this student has narrated every one of his thought processes on his homework. I do not need diagrams explaining how to read numbers!
or a reminder of the values of hexadecimal digits on EVERY QUESTION
just destroyed my nose with too much onion in coleslaw, and destroyed my spare ribs with too much heat
playing jumpman lives! loving it
@aperfect damnit!
I'm going to read some more Jeeves. Nothing else is presenting itself for my attention.
@GreyAlien no way, skidracer has just offered to help with music for the game!
on a seaside adventure. Blyth beach is lovely and calm, like the kind of thing you'd find on a model train set
lovely sand at blyth. Don't know why newbiggin felt they needed new sand. How different can it be just a couple of miles up?
wind's beginning to pick up
spent an educational 15 minutes driving through blyth town centre following signs for bedlington.
now at cambois beach. Not much here apart from a pair of wind turbines sticking out of the ocean like neptune giving us jazz hands
had to drive through blyth power station to get here by the way. Don't know if it still exists, but it felt like i was becoming its fuel
there is a big ol' pipe at cambois which spews out sewage, and a dogging site where gays, it would seem, are not welcome
first sensation that welcomed me to newbiggin-by-the-sea was the smell of dog poo. Let's see if i can see that statue
these kinds of things are meant to be engineering marvels, not sensible compromises given situational constraints
RNLI were washing out their shed. Nice and warm here, pity about the rest of it
took the wrong turn off the coast road but ended up at QE2 country park. Lovely! It's got swans and a big lake and things.
arrived at druridge bay country park. Not the same thing cp druridge bay itself! Leaving, lovely scenery but no way i'm paying and displayin
was enticed to hauxley by a nature reserve. Lovely place! Good georgian buildings. Seem to have found the coast again.
brought a moleskine to write in but i'm using twitter instead. Which is more pretentious?
just noticed shozu hasn't been geotagging anything since blyth! Arr
failed to exit Amble pointing in the correct direction, hungry, clouds arrived, so I've come home
had a flash of inspiration for fencing controls
I concede defeat to this bug. It has me absolutely baffled, and is a show-stopper
fixed the bug! stupid y axis, hiding from me
@arowxGames another blitzer from the north-east! (I'm warpy on the bb.com forums btw)
@aperfect the internet is a scary place
at the barber's. Thought i might hit the lunchtime rush but apparently there's no such thing in pity me
@JSlayerUK I once accosted tony benn in the street at the miners' gala. he is a funny person
game is back on track. Had a brainwave
a whole month until the f1 starts! can't wait
@GreyAlien well done! Is 64bit support for the bigfishgames app in the works so I can try it out?
@GreyAlien I clicked that, but then the installer says "failed to open file for writing" for every file
@GreyAlien maybe just store tiny black/white pixmaps of each character, and apply effects at install/run time
@GreyAlien actually, just remembered my dad wrote the first ever kanji gui. I'll ask him how he did it
March
@GreyAlien if you're around, get latest github version of game, exciting new gameplay!
man, the end of being human was such a let-down
this student writes like a 4-year-old! getting on my nerves

@JPickford is that in reference to the thing about boy ducks? I can't begin to see the connection between those things.

@ShoZu just tried out twitter uploads, couldn't the url be shorter, something like tw.shozu.com/shortkey ? The truncated long url looks odd.

@JSlayerUK last time I had that done, I met an old school friend on the street afterwards. It's very hard to not look crazy in that state
@aperfect genetically, I am glad I only got autism and not hayfever from mum and dad
@fatfieldfoodie bought streaky bacon 2 for 1, and some posh bbq sauces. I think I was too early, some stands were empty
@JSlayerUK woooooow, those are really good!
I have basically no decisions to make about what to eat for the next week or so
@Alternativemeat bbq yesterday was a big success. Impala sausages were the consensus favourite, but I didn't get any!
opulence: using charbonnel et walker and clotted cream ice cream to make a chocolate milkshake
should I make a mockery of amazon prime by ordering a 79p box of chalk to be delivered tomorrow by special delivery? Tempted!
@GreyAlien that was the temptation! Such enormous pointlessness is like performance art
@rockhyrax I used no sugar. Is that something you're meant to do? I just sort of blended everything together and it was ok, I suppose.
Fol Chen's "In Ruins" sounds like the intro theme to a totally kickin' 80s movie
@JSlayerUK that puts you one up on Dick Cheney
aaaaaahhh! Why do we not subscribe to the journal of mathematical sciences?! WE'RE A MATHS DEPARTMENT
@Amy1306 at least you're not male
New mathem-o-blog post: Infinite trees are $E_3$ (maybe) (http://bit.ly/9l94cP)
@rockhyrax YES. I have to start one of those now.
came into uni to be productive; left my usb stick at home; sheesh
finished Limbo. Good, but not worth a tenner
@Bishnavitch potentially, if it's a late-ish showing
@peterrowlett now I want to make a Magic Pi picture. Maybe it could be a mobius strip, for full maths art cliche effect.
for the first time since the Little Ice Age, my flat is warmer than the air outside it
If this old man was a transformer his name would be Insane-o-plex and his special power would be creeping me out

@GreyAlien ahh, I'd always wondered about that! oil change places are everywhere in the US
In mourning for Tanfastic, the shop with the best name
@aperfect god damn it I made that joke last weekend!
@aperfect in front of bish, discussing wraps
I have had to deplete my Strategic Reserve of pound coins because domino's isn't taking card payment. I might regret this.
@JSlayerUK you don't need people, you need Soupy Norman
just realised last letter of my bank password needs to be a repeat because it only appears in the last box, so could be deduced
@rockhyrax much more mundane - my wallet doesn't have a coins bit, but I buy a sandwich every day for lunch, so pounds accumulate
@JSlayerUK if you're considering it, don't bother with Gordon Ramsey's Plane Food. It's only so-so.
@alexbellos I think so; that rings a bell... (pun ENTIRELY intended)
@rockhyrax what's going on, are you playing a mad combinatoric variant of musical chairs?
the best thing ever! RT @divbyzero: RT @pickover: Please enjoy this shiny fractal cow. http://bit.ly/cvCEDA

@beefok no! functional please!
@beefok anon functions alone are worthwhile but haskell is like writing pure maths. Lots of clever optimisations can be done by FP compilers
@ColinTheMathmo it was underneath a Dan Brown book. That was the bit I found hardest to believe in the whole episode
This woman's handbag looks like the oogie boogie man.
and I thought "Genuine all-over tan 'an impossibility'" was going to be an application of the hairy ball theorem http://tinyurl.com/25av34j
@brittneybean doesn't seem to work. After I click play, nothing happens
Making eye contact with people would be a lot easier if I could tell when they are making eye contact with me
@fumbleweeds I'll swap you. It's all overcast and horrible here. I had the heating on this morning!
The rabbits in the park are so bad at hiding. Where have the birds of prey gone?
if Oliver Byrne had had access to a 70s graphics terminal, he might have made this http://bit.ly/cwyoHW (@alexbellos)
@brittneybean giraffe is mine, hands off. On my wall it would say without words, "a tall man lives here, but don't worry, he's into cuddles"
@brittneybean I'm ok with that as long as his middle name is Raphael, so his rapper name would be G-Raf.
@brittneybean every now and then I consider complaining about a song but then I get a sense of perspective and do something worthwhile
my computer's failing in a very cinematic way - the sound is going all mechanical, graphics are jumbled up, but nothing has stopped working
@peterrowlett you could mention the release of MathJax, which will help maths on the web a lot. It's sponsored by the AMS, Elsevier, etc.
catching up on five years of PC games. Where to start?
@Bishnavitch curry. What's wrong with you, that's not a hard choice.
@GreyAlien that was the last game I bought!
@alexbellos if you can check an answer to a question in not too long, does that mean that you can find the answer in a similar timescale?
Two women, both wearing weird asymmetric work trousers but normal casual tops, waiting for the metro. What?
@alexbellos yes P = probs s.t. solns can be found in poly time, NP probs s.t. solns can be checked in poly time. P is in NP, but is NP in P?
@alexbellos oh dear. @standupmaths 's job is safe.
@brittneybean apart from the super mario bros theme, which is the achievement of our age, Outcast had a good score
@brittneybean ahhh I take it back! I forgot Monkey Island! http://bit.ly/dmURvO
@aperfect that's cheating, it's film music!
@aperfect ok, I concede. Can't spend time arguing, busy looking for a lynx emulator
@aperfect "even the Guardian"?!
fixed three really small bugs today, good work. Now I will play games until my eyes have a serviceable map of q3dm17 imprinted on them
going to make a sarky comment on a facebook post but can't find the crucial corroborating evidence to back it up. Victorian txtspeak anyone?
to expand: fairly sure it was a metafilter post about txtspeak-like abbreviations in wide use in 18/19th C letters, with famous examples
Yes! The champion difficulty space in Eldon garden multi-storey was free. There should be an Xbox achievement for using it
me to Max: "don't wear shoes, dog!" Where does he get his ideas from?
@brittneybean the Naked and Famous: Larry Flynt has that Venn diagram on a stained glass window in his office
@MathJax ah! can fonts be stored on a separate server and not break cross-site scripting rules? that helps a lot!
@Bishnavitch I thought I had fast-forwarded five year and I had become a bigoted professor. Is Dr Christian off that street doctors thing?
@aperfect yes
The dog is suspiciously cooperative today, and I doubt that my lectures on the value of collaboration were what turned him
@GreyAlien because the IR light is weaker, so by pressing harder we're holding it down for longer, so light has greater chance of being seen

someone's subscribing to my Interesting Esoterica maths collection on Mendeley! Now I feel pressure to find more papers
@divbyzero have a look at www.mathjax.org - yeah it isn't built in to the browser but it's ace and supports all of amsmath
@trackinthebox your emails have had  characters littered about them for the past few days
@brittneybean windows live mail. Good point - they're not there on the web interface
I lost my place while cleaning my teeth and ended up just brushing teeth at random until it felt like two minutes had elapsed
@alexbellos tl;dr: Efalex - suppliers of brainboosting omega supplements - sponsored his latest creation
@brittneybean my complaints about that article's logic last longer than a tweet
@aperfect it doesn't even make any sense, it's meant to be a page with the corner folded
incompletipedia: article titles ending in an ellipsis: http://j.mp/c5skcK
@peterrowlett just saw a very old book in Sedbergh on that subject. Bought another Hazel Perfect group theory book instead though
Being stalked by a van from wessington cryogenics. In stasis, no one can hear you scream for 80 years or so
that's nice, Vexed is very funny. I'll watch it from now on
@Electrokittie which is why you're now an Avon lady?
I need to get myself a tube of Eczemate, the only skin moisturiser endorsed by five reigning grandmasters
@aperfect yeah I'm amazed you've never heard of it. It's some guy's petty revenge for Mt Rushmore being scraped out of a sacred mountain
@aperfect do you get any nihilists turning up?
@trackinthebox I played Parov Stelar at a party last year and it got a stonier reception than an Iranian adultress
@Alternativemeat I prefer to view the ageing process as me continually setting Personal Bests for time spent on Earth
@brittneybean the moves he starts pulling at 1:24 are deadly serious.
11pm Wednesday radio 4 comedy is my favourite time, wavelength and genre combo http://beta.bbc.co.uk/i/tgf1c

@rockhyrax just had a look into allowing sequences from the OEIS but they don't have a nice API which gives enough elements
@Gelada feel free to re-use my javascript prime birthdays thing (http://j.mp/93Psj6) on primebirthday.org. It's very simple.
aaarh, now that's a third conference happening while I'm on holiday!
@standupmaths not undetectable, they told manufacturer how to detect & avoid it before they published. It's just a man-in-the-middle attack
@tynesidecinema please could you fix it for me so tynesidecinema.com redirects to www.tynesidecinema.com? It's always annoyed me
@alexbellos fairly sure I could make a necklace which could describe ALL of pi

@badmachinery what's your policy on fixing typos? "bgger" in today's first panel if you are pro-amendment
@aperfect oh it's a problem with your phone is it?
feel like achieving today. What to achieve? Your achievement suggestions, please!
@MarcusduSautoy that means set of uninteresting numbers is not well-defined, not that it is empty
@rockhyrax vanilla assassin. Be afraid
@JSlayerUK his face would probably benefit from a collision. No, that's harsh. Helmets aren't a legal requirement: http://j.mp/cAPUNa
@JSlayerUK yes that's important, but slightly inappropriate statistic. Replace women with 'world's pooreest X %' and you'd get similar
@JSlayerUK that's a fair compromise
is it just TeX that turns the letters 'fi' into a ligature which can't be copied and pasted correctly, or all PDFs? IT ANNOYS CP SO MUCH

@Rosalot I thought you were a mackem?
@peterrowlett was going to tell you something interesting about symmetry and the Alhambra, but it's completely sold out. Wasted holiday!
No tickets available for the Alhambra and I've got food poisoning. Poo.
Cuboid walks into a bar. Barman says, "why the long face?"

@divbyzero not to my knowledge. Geometry hasn't really had the pop-sci treatment at all, apart from golden ratio kooks
@peterrowlett I started with diagrams on mine - tesseract, sierpinski, etc
@divbyzero yes, maths teachers have been overly optimistic about what is well-known since time immemorial
The man next to me is not happy with his career choices. He is expressing this by playing games on his blackberry and sighing a lot. How sad
Oh no I've become one of those people who gets up ten minutes before the train stops. Blackberry man's awful worldview has contaminated me
@divbyzero thanks for that, added to my interesting erotica collection
@divbyzero sorry, was in reply to you sending me "misconceptions about the golden ratio" ages ago. I've just got back from holiday
@divbyzero oh god, just realised I typed erotica and not esoterica!! Oh dear oh dear!

ahhhhh rubik's deja-cube! I've just shuffled it into the exact same position as the last time! CAN'T HANDLE IT
@JSlayerUK your last tweet is magic and I have informed the Witchfinder General
@theyellowstereo it's not a laugh track, it's a live audience
English tests to gain citizenship are terrible and wrong, but I would advocate the compulsory removal of soulpatches
@divbyzero the sad thing is, they know the kind of people who dislike that ad are outnumbered by those who like it. They've done the math :(
@Electrokittie are you basing this on the new bit of Eldon Square, which is right next to where lots of chinese people live?
@Gelada I was really just going for a bit of irony with "do the math". The advert doesn't bother me
A Town Called Panic is on at the Tyneside on Friday. I am looking for people to see it with. http://j.mp/9NOjfg

pepsi are running a competition where a camera is given away every 10 minutes. Don't enter at lunchtime with the masses, so when is best?

@aperfect so 3:50 is the logical choice

@brittneybean don't worry, in 10,000 years Science will be able to make you sane again
@tynesidecinema has anyone said a town called panic yet? But only if I get to be the crossing guard. He's got everything in that shed.
@trackinthebox I wish to show my appreciation for good tracks, but am not obnoxious enough to post to facebook. Could you add a like button?
Worried my last words will be tedious, so "Rosebud" means more morphine and "this is the last of earth! I am content" means change my bedpot
@tynesidecinema did one better than RTing - I emailed the whole uni maths department. I may or may not go myself
@brittneybean is that like half a Yakoff Smirnoff joke?

music people: what's the point of putting songs on the radio before the album's out? I'll have forgotten about it by the time I can buy it
@brittneybean well then, clearly the radio I am listening to is too avant-garde. I suppose with "Radio Nova" the clue's in the name

@brittneybean are they error-correcting codes? There's maths to assign codes so that typos can be automatically corrected. I can help if not
@standupmaths so could this be an "only guaranteed to be true once every 365.25 days" fact?
@brittneybean suppose assign 10 codes. Instead of 1,2,3,etc use several digits, so if user mistypes, can work out correct code automatically
@brittneybean the maths to show why it works is quite involved, but to implement is just a couple of lines of code

@Gelada just had to send someone a link to my klein/slinky video and I noticed I'd abbreviated you to "Ed Harris"! Corrected to Edmund.

@gingerbeardman thanks! Maybe you can help me: do you know how to get the screen position of the input caret?
@gingerbeardman I tried that, but then you have to do text metrics to get the rest of the way, and it wasn't working for me.
@gingerbeardman if the cursor is inside maths delimiters, I want to show an instant preview of what they're typing above the cursor
@gingerbeardman are you on google talk or anything like that?
I've updated my write maths, see maths thing with even more instant maths preview! checkmyworking.com/misc/writemath…
@gingerbeardman try a very short line - I realised I need to get the input's scroll if it overflows, and haven't fixed that yet
@aperfect <C-w>v ? That was like no.1 thing I wanted to know.
@brittneybean adult, or... TERRIFIC BORE
@gingerbeardman preview box should work now. the scrollLeft property of input elements is what I wanted!

Petrol is £1.31 in Byker! God bless you beautiful Libyan freedom fighters! Or are we not meant to talk about that part?
Man that last tweet was unacceptably sarcastic. I hereby resign my post to spend more time with my stuffed animals
@JSlayerUK did she have an Excellent Irish Nun Name?
why can't I do a simple box-circle collision? What has happened to me? I resign for a second time today to spend more time with my textbooks
@stecks that was world record Most Contentedly Lonely Dude attempt. Trying to beat man who watched all Friends dvds in one sitting last year
@peterrowlett @Samuel_Hansen only hard math is patentable arst.ch/qlf
@Bishnavitch no!! I'm at maths-aid until 4
@Bishnavitch can we not get a couple of hours in? I can give you a lift back into town
@Bishnavitch 4.30, it takes me time to get home!
"the man who annoyed Adolf Hitler" - understatement from BBC News. As history shows, rather a lot of men annoyed Adolf Hitler
@mathsinthecity that *is* a nice jumper! I have no nice jumper and my maths explanation videos are a shambles. :( :(
@mathsinthecity sadly, finding jumpers able to enclose my considerable length is v hard. I might never be an eligible mathmo :(
@brittneybean @aperfect Crayola's colour names are almost definitely copyrighted/trademarked. Look here: code.google.com/p/color-js/

@Electrokittie if you send me your email address I will invite you to google+
somebody please do this: git log --oneline --graph as a level for California Games BMX. More collaboration => bumpier level
@CloudoidLtd there's a bit. The way I'll be doing it is, I will sit in the pub until people turn up, then we talk maths!
@standupmaths dude, that band has holes in it. Not mobius.
I've finally got round to putting on the t-shirt I bought at Bletchley Park, and it's a *women's* XL! So annoying!
@MathsJam can anyone coming to Newcastle MathsJam please please make sure to email, because I've got no idea how many people will be there
@peterrowlett @Samuel_Hansen which one of you is responsible for how quiet this week's #mathmaths is? Resign!
a note you don't want to see from your supervisor: "yes (as long as 0^0=1, which it seems to here)"
@peterrowlett a survey answering that question should also establish the belligerence of those who don't like pizza.
@CloudoidLtd will you be coming to mathsjam tonight?
@CloudoidLtd go on!
Newcastle #mathsjam is go! Starting with @peterrowlett's 16 dots puzzle. What else should we do?
Trying to find equivalence classes of solns to the 16 dots puzzle. My group theory failing me, @E_I_W breaking out some graph theory
@MathsJam to your question. You need to follow me so I can dm you!
@MathsJam @peterrowlett talking of fields: why can't you grow wheat in Z/6Z? Because it's not a field!!!
today on my arty maths blog: etsy finds, with a prime number counting chart for the baby you hope is cleverer than you artymaths.tumblr.com
@plusmathsorg if you had the conventional selection of 'share this article' buttons, I would use them for this article.
seems librarian is explaining the concept of the book to these people. One is staring at a page but sort of past it like a magic eye picture
if I didn't know Green's theorem before, I defo know it now. I've explained it to a bajillion students today before the resit this afternoon
@jamesgrime your local dude with a laser-cutter should be able to do it
I ate a very spicy pizza last night so I would wake up in time. That worked, but there were... side effects
ok guys, I'm going to spend some time horse fishing in Flanders, going to sort some things out about myself youtube.com/watch?v=ZT7WBt…
@brittneybean That is a pretty silly picture. And is the article about foreign firms hiring Koreans?
@brittneybean there you go! I can see no problem with the caption
There is a lot of yellow happening on me today, apparel-wise. Gotta beat those rainy day blues
@peterrowlett unexpected satire from local podcasting hero
@Electrokittie if Stalin had stayed that thin would history have judged him so severely?
@standupmaths haven't you seen those before? Seems to be based on what this guy did in '96 graficaobscura.com/lasercut/surf.… graficaobscura.com/surf/index.html
I've made a career decision! I'm going to start a blog of videos of children being told old jokes for the first time and just losing it

@ColinTheMathmo about Q7: what if I'm not too keen on the given Star Wars characters? Can I write in Chewbacca somewhere?
@ColinTheMathmo I went with Lando, the closest match (old friend of Han, alright with a blaster) but I'm not happy: I still got Apologiser
@matthen2 is that a tautology, or have you got an example in mind which looks like it should give a different answer?
from now on I will be using prettycolors.tumblr.com whenever I need to pick a colour
@plusmathsorg I thought you were a maths magazine?
@aperfect hardly the coding rockstar lifestyle. More like coding support act with like two fans at the back who half know one of the songs
Man, there's something unusual I meant to put on my shopping list but all I can think is 'reticulated splines'. Curse you, SimCity!
@trackinthebox oh no, double grammar mistake today! practise - verb; practice - noun. Practice makes perfect; practised group.
@peterrowlett *ahem*...
@peterrowlett yes. what does it involve?
@Gelada when you said facial topology I thought of this page.mi.fu-berlin.de/polthier/artic… in the Hilbert room at Goettingen
@HoeJodgkiss how long would it take for a new Newcastle club to work its way up to the EPL? Less than for NUFC to sort itself out, no doubt

hooray! my Gauss Fact got put on the site! gaussfacts.com/view/Mathemati… but boo, I *just* missed having fact #500
@standupmaths thing that annoys me about glasgow's map is that they have "inner" and "outer" lines - why not clockwise and anti-clockwise?
@standupmaths because many cities are laid out along a river, so a tablet shape means less squishing at the sides
@brittneybean @aperfect there's so much bad maths in that poster I don't know where to begin.
@brittneybean @aperfect also, it's so badly designed I literally don't know where on the page to begin
I've bought a rotring tikky graphic pen. Using it is like writing lullabies for baby rabbits on softest vellum. Best pen ever.

@NoelAnn I think your twitter account's been hacked
suppose you open a clementine and it's all shrivelled up inside. Do you still eat it? Is it worth powering through the awful texture?
never mind, twitter, I just answered my own question. The answer is definitely no.
@enoFsamohT @Electrokittie well that's put me off my lunch, dinner and tomorrow's breakfast
Imagine being a boiler repair man. Everyone you meet all day is unwashed and smelly. Yeesh.
@brittneybean Jimmy Fingers and the Fingerbowls! Cholera Squad! No, it must be The Reappraisals! #mightaswellbeforallicare
Does anywhere in Tynemouth sell freshly made doughnuts?
@haggismaths so you need to post the link
@CloudoidLtd ah man, I just walked past there!
@Electrokittie it goes the other way too, viz Oswald Mosley
phew, didn't completely ruin @peterrowlett and @Samuel_Hansen's podcast through technical ineptitude. They make it sound so easy, and it is!
@standupmaths I spy an opportunity for an extremely tedious google maps mashup cataloguing the arithmetic road signs of Great Britain.
@peterrowlett forgot to mention most interesting thing about my week! Every single student doing resits needed Green's Theorem explaining!
@peterrowlett ... if I didn't know it before, I certainly do now
@NoelAnn what does that mean? Support increases as deadlines approach, or having deadlines at all increases use of maths support?
@NoelAnn ok, that matches my experience. In fact, students turning up not just before a deadline is a notable event
@jcoglan man I thought I was so cool registering a legible .es domain a few months ago, but now everyone's got one!

aaarg vim-latex-suite, why do you rebind the way line deletion works? That has nothing to do with LaTeX, that's just your preference!
@aperfect that's worse than those french dudes!
@RANIELDANSON chin up, young man!
@kenfodder fairly often
ligatures count as single-letter variable names, right?
@mathsinthecity much worse: set theorists ruin your day in uncountably many ways at once.
@aperfect but I'm writing LaTeX!!
ok twitter: BLT pizza or piri-piri chicken pizza?
ok guys, time to get serious and do some blue-sky thinking outside the box: tuna mayo pizza. What do we think?
@elinoroberts Jeera. North Shields. They deliver. Nobody needs to know.
@Bishnavitch I used too much piri-piri spice and now I am blind. I blame youuuuuuuuuuu!!!
what's it called when you decide that the correct use of semi-colons *does* matter and then taking part in society becomes unbearable?
@standupmaths "going". Future-proof.
leadmees is a fun kinect game. It's like Lemmings, but you carry them around on your shoulders
You dawg, I heard you like eggs, so I made you an egg mayo sandwich, do you can eat eggs while you eat eggs
@plusmathsorg v interesting bit of synaesthesia at the end of that - i've never thought of the number line having a bend, or being vertical
@alexbellos that is a really good read, and it will fit in well with my Interesting Esoterica collection mendeley.com/groups/519971/…
@elinoroberts excellent. And, "Donkleywood Bastle" is a real thing and not just an arbitrary selection of syllables.
how have I suddenly got three new people following my Interesting Esoterica collection on Mendeley? Are you twitter followers, you people?
talking of mendeley... from the creatively-named papers collection: mendeley.com/research/a-wom…
@standupmaths sign me up for a big box. Our university marks-recording scheme thinks ratios become percentages by sticking a % on the end.
@peterrowlett it just sticks the "and others" bit on regardless: I know my last tweet has only been retweeted once, but it says "and others"
@peterrowlett it might have something to do with the way twitter stores tweets - they're not all available on demand.
@peterrowlett or maybe the original tweeter counts towards the retweeting total
"Texts aboput [sic] quality in e-learning." EXCELLENT QUALITY
@Gelada is that going to be something like, 'least sequence not in Sloane' then?
@HilariousCow so: yo Colonel Gaddafi / I'm not gonna miss you / Much like month-old taffee / your face looks like pig poo.
@HilariousCow on the streets, they call me MC Hasn't-quite-got-the-hang-of-scansion
@CloudoidLtd nice! reminds me of the kind of textures you saw in 90s games like Quake
nice man 3d-prints mathematical objects: metafilter.com/107301/The-mat…

@Samuel_Hansen collecting all your unmanageable deadly sins into one easy bout of gluttony, are you?
@peterrowlett what help is needed? I think she's got it.
@peterrowlett parsed joyfeed as a name. Probably isn't. Man or woman?
very good javascript maths scripting thing calculize.com entirely numeric, so no nice typesetting or symbolic manipulation, but cool.
@CloudoidLtd could you make an AI chase the cursor on that surface? geodesics are fun to compute
@CloudoidLtd look here: somethingorotherwhatever.com/kleinsteroids/… (I might have spent a bit too long on this)
@CloudoidLtd I have written cleverer asteroids AI in the past: somethingorotherwhatever.com/?thing=antiast… wouldn't be hard to add that logic to this
@plusmathsorg curse you both, Navier and Stokes! (I'm copy-editing today. Accuracy is v important to me right now)
Look what's just arrived! twitpic.com/6jzigl
@peterrowlett @Samuel_Hansen aahh man, I thought you'd finally made a #mathmaths without me in, but at 46m there I am! Try harder next week.
@peterrowlett @Samuel_Hansen #mathmaths 65: @christianp-free zone. Make it so. Don't even mention this tweet.
@IOPscience good stuff, but with MathJax turned on all inline maths is surrounded by dollar signs.
This is your one-week warning for Newcastle #MathsJam! Bodega, Westgate Road, 20th September. @CloudoidLtd @elinoroberts @jjsanderson
#MathsJam is a monthly opportunity for like-minded maths enthusiasts to get together in a pub and share stuff they like.

Aarg, flat tyre! Thank god I managed to get off the central motorway. I would *not* have been able to cope with holding up that much traffic
@elinoroberts good luck!

@peterrowlett nobody wants to humour you.
@peterrowlett PS: that is not something you can mention in this week's podcast
@peterrowlett I would've gone with "irreproducable"
last.fm is recommending music based on tracks I've only listened to on last.fm recommended! It is constructing its own version of who I am!
@brittneybean have you checked if you can get BE?
@brittneybean that is the worst reason for not having BE!
@brittneybean I've got the moving process down pat: move in, call BT, wait 2 months, complain to BT, wait 1 week, call BE, internet next day
@aperfect @brittneybean that's because you were giving them more money. If it's the same or, god forbid, less, they don't care too much
@jcoglan however my domain, somethingorotherwhatever.com, has been put to good use for several years now
@rockhyrax your voodoo doll of me is strictly non-canon
@rockhyrax "It is constructing its own version of who I am" ... "doesn't everyone" ... etc
@brittneybean I don't know, but you've reminded me I haven't looked at uniqlock in a while

@jjsanderson that's some good hashtagging. Good cycling too!
@aperfect uhhh hello i have made my pictures arty by making them black and white because colours are the tools of the man
@aperfect they're nice pictures though
@georginabrett is there any more to your site than the player thing? it's incredibly hard to read!
@pianomaths accessibility of things is not a Euclidian metric

Newcastle #MathsJam is tonight, 7pm, The Bodega, Westgate Road. The idea is, we sit in a pub and discuss enjoyable mathsy things.
@ben_nuttall only two, because we were all leaving.
@JSlayerUK was it HDN? I think with them everything goes via Birmingham

@alexbellos @mathpuzzle @Grabarchuk if I've got it right, they're the common names for the combinators sufficient to produce lambda calculus
@jamesgrime have you tried Virtual PC? microsoft.com/windows/virtua… Wine might do it on macs, but I'm not sure
@Htbaa yes, that seems to be wrong!
@Htbaa it just means there's no unique solution of the equation. Any value of a will work.
@Htbaa what answer did you get? If it's a single number, I wouldn't give you the marks
@Htbaa or 0=18, which is a contradiction. So I should have said there is no solution. Are you absolutely sure you copied the equation right?
@My_Metro that's it! Can't let this slide any more: *you're* using *your* wrong.
@Htbaa you had an accident before where that second 3 is now.
@Htbaa stupid predictive text! I meant you had an a before where the second 3 is now
@AdamJackzon 9 Northumberland terrace, Tynemouth, ne30 4ba. We're currently at cragside, so come for 7.30. Bring alcohol if you require it
@elinoroberts do you consult iain's shoelace website?

nexus, why do you need a captcha on the metro pass renewal form? To stop automated do-gooder robots from topping up people's passes?
I used to think only Springer hated me and wanted me to remain ignorant, but now I need things from other publishers and they hate me too!
"Lecture Notes in Computer Science" definitely sounds like the kind of thing we should have access to

ok, I need to go to Shanghai! This is the single best thing on my arty maths blog: artymaths.tumblr.com/post/107227047…
@peterrowlett how many different people were the emails from?
downloading Bajka's concept album based on The Hunting of the Snark. It didn't sound great on preview but you can't ignore those ingredients
@standupmaths have you seen any of those Mega-RVs that tow an entire SUV behind them?
@soupie66 @standupmaths Iwouldn't - that's not a \cdot!
@peterrowlett to compute average emails sent per person
@peterrowlett you said "am I part of the problem?" Spse one person sent you all 300+ emails. Then you're at most a small part of the problem
@peterrowlett further: suppose each person sent ~equal no. emails to same no. recipients as you. Can then compare yourself to them.
@jjsanderson @standupmaths paste this into your URL bar or make it a bookmarklet. It loads MathJax. Put TeX in $ signs. pastebin.com/p5Tqqtj5

@kirel what needs to be done? Email christianperfect@gmail.com
@mathsinthecity my feet are getting all climby just looking at that
@ColinTheMathmo pointless but not pointless? Is this another clopen type thing?
@ColinTheMathmo oh man, should I have added a winky smiley on the end of that tweet?
@ColinTheMathmo you're just too helpful
now I'm sad :( youtube.com/watch?v=Eg4s2-…
@ColinTheMathmo @mickybullock would a tablet connected to a projector do?
@Gelada very interesting! Feedback is the big thing I'm thinking about at the moment
@mickybullock I'm thinking a tablet running a geogebra applet through jsxGraph, connected to a projector, would be a cheap alternative
@ColinTheMathmo @peterrowlett isn't that enough? Only you and he were the intended audience
Even this early it's too hot! I'm going to stay indoors eating ice cream all day
some or all of this bowl of coco pops tastes completely foul
@plusmathsorg forwarded to my bored optometrist friend. Maybe she will contact you!
oh no! I bought apple _and mango_ juice because it looks the same colour as normal apple! I think I need a helper animal to do my shopping
@brittneybean just gonna sit back and bask in the glow of that shining example of marketing
@aperfect you're lying to me and to yourself
@mathsinthecity compare this bridge en.wikipedia.org/wiki/File:Iron… (1781) to this bridge flickr.com/photos/aperfec… (1866) maths made it better!
@mathsinthecity slight correction: taken by the brother who prevents me from breaking his servers further.
@mathsinthecity would've added a snapshot, but not completely sure of bridge maths chronology. Forth bridges better show the progress anyway
@mathsinthecity forth and fifth tied, hence forth bridgeS

@alexbellos don't make me do it! I'm trying to wait until a replica can be 3d-printed
make an icosahedron with paper plates! wholemovement.com/index.php?opti… I will be trying this later, and maybe at the next #MathsJam
"I have for the last twenty years been folding paper plates seeking to understand process and the comprehensive nature of the circle."
@for_the_winn I don't think so. I was using jcarousellite, but it didn't like having different-sized contents, or changing contents
@peterrowlett what happened to this week's #mathmaths?
@peterrowlett you normally record on Saturdays and spam twitter with requests for news, that's all. If it's coming, I'm happy
@HoeJodgkiss your witty tweet reminded me of something I just about remember and have nostalgic feelings about! Two twitter points to you!
@HoeJodgkiss ok, but twitter points are pegged to the Somalian shilling at 1:1 conversion
@Gelada I will try that with mine!
@mathpunk doesn't matter what a and b are - draw lines from C to points where AB intersects circle. A bit o' Pythagoras later, e is found
@mathpunk ok, that works
@aaronpk @mathpunk are you just trying to work out if a line intersects a circle?
@aaronpk @mathpunk then you want the distance of C from the line AB paulbourke.net/geometry/point…
@aaronpk @mathpunk and I think I've got some code somewhere for the same with halfspheres (great circles) if that's what you're really doing
@aaronpk too much to explain in a tweet, so I've written some notes: takenot.es/?line%20circle…, can expand if necessary
can anyone recommend a reliable place to have an MOT done near Tynemouth?
@aaronpk well, I have some code at github.com/christianp/war… (lines 136-209 most relevant) my notes page is editable, so add any questions
@ColinTheMathmo are there spaces left for 5min talks at MathsJam 2011? Can't find the page. Would a non-puzzle talk on web maths tech be OK?
@jjsanderson thanks, I'll give them a go
@ColinTheMathmo never mind, searched through your past tweets and found the form
Just gave the car mechanic all my keys. Let's hope somebody's already in my office
@peterrowlett I bet if you asked twitter nicely, you could raise enough skype credit to call @Samuel_Hansen's real phone an hour each week

How is yahoo groups so bad? Seriously, try to do *anything* on it..
@JSlayerUK what's up?
@JSlayerUK which is why I buy in bulk and spam the world with pens.
@Bishnavitch turn your phone on!
Four videos have gone missing and now vimeo's uploader won't work. The universe just doesn't want this project to happen.
@peterrowlett as someone who also hasn't read the Apology, some more quotes for the points you rebut would have been helpful
@peterrowlett hyperlinks to gutenberg then? What's the point of making rules if you can't subvert them yourself?
@peterrowlett pooey!
@mathsinthecity there's a very good article in the latest Cabinet magazine about wimples. Some good maths, too.
@ThomasEWoolley What counts as a brainteaser? Anything with a half-life ends up involving exponentials
I think I would do just about anything for one of these chickens flickr.com/photos/andysin…

maths-problem CAPTCHAs do pretty much the opposite of what you want

@jjsanderson my site often doesn't resolve with Be's DNS either. What could they be doing wrong?
@peterrowlett just to check - you are still in email hell and haven't forgotten about that eassessment thing?
@mathpunk the graph of flow of information is complete - any node can send/receive information from/to any other node
@mathpunk ok: the geodesic between any two nodes is either 0 or 1
@mathpunk ...where any two nodes are connected if they can send information addressed to each other
@mathpunk information-as-resource. What's the difference, anyway?
yo, @Bishnavitch, I'm really happy for you, and Imma let you finish, but Quake was the best game of the century

@standupmaths maybe it doesn't matter: does it have an old, be-clippied version of Office?
@standupmaths ahhh, I think this is one of those quirks about Gill Sans or some other London font... I'll try and find a link
@standupmaths it might be Johnston ask.metafilter.com/187854/Busspot…
@mathsinthecity will there be a mathsinthewrongcity.com for us commoners in the provinces?
Even though I'm carrying a cake tin decorated with a pastoral scene under a rather chic umbrella, I'm a very manly man really. Ladies.
Vindication! @aperfect @fatfieldfoodie RT @schregardus: Researchers turn iPhone into 350x microscope on the cheap j.mp/oQHPYV
@mathsinthecity a side effect of your RTing of me is that I noticed your no. of followers has rotational symmetry. A cause for celebration!
so is the Rustici SCORM reference deliberately wrong? This has caused me masses of problems
oh, so in fact the SCORM spec itself disagrees about what the multiple choice type is called. Thanks, American military contractors!
@stecks I would definitely leave some of those in the reception of our department, if I had some
I think I've just contracted, like, cheese AIDS. That cheddar was *well* off
at least the sour cream hasn't gone off. Jardine's kettle chilli will punish you if you do not provide it with accompaniment
@mike_rustici interactions.n.type should be 'choice', not 'multiple_choice' - that's the name in the IEEE spec, not what you send to the API
@mike_rustici it took me quite a while of reading the spec to work out there's a difference. Still not sure *why* there's a difference
@HilariousCow oh that is a hashtag that needs to just go on and on
what do you do when you wake up early and read all your internets before you're ready to get out of bed? It's too cold to get breakfast
@brittneybean one of the many lesser-known discoveries that the Laboratoire Garnier does not get enough recognition for
@aperfect oh no, burgers aren't the next _thing_, are they?
@benkenyon bravo!
@HoeJodgkiss john lewis stripes, down your flanks
@stecks the numbers seem to be in base 26.86!! That bill is ENORMOUS
@brittneybean she's got previous, viz. the Oops! I Did It Again video
@theyellowstereo hooray the graboid! But as always, I've just let it play in the background and not note which albums I should look up
@Samuel_Hansen I want to send you a good maths teacher story, but Solid Britishness prevents me from being so earnest
@theyellowstereo good picks, though! I don't think I'll mind having a second listen through
@aperfect maybe they'll send you a diff so you can go to your branch and revert the changes. #versioncontrolpunsarethebestpuns
@jcoglan "unusable"
man, I thought I'd give the ballet at the theatre royal a go, but not at £30 I won't.

@peterrowlett how long since you last did Benford's Law?
WHY HAS NOBODY MADE A SEQUEL TO 1998 CROSS-PLATFORM HIT "GLOVER"? THIS IS MAKING ME SO ANGRY RRRRRRR
@peterrowlett seems to be enjoying a resurgence. economistsview.typepad.com/economistsview…
@peterrowlett not sure, but it's fun to talk about.
also: WHY CAN'T I BUY A FALKPLAN OF THE UK? THIS IS MAKING ME EVEN ANGRIER !!!!RRR
lovely fan-made Tintin title sequence vimeo.com/30402976 . Better than the 3d version, @MarcusduSautoy?
@peterrowlett @pkrautz @Samuel_Hansen christian does not. Should I? I haven't listened to the latest math/maths yet
@mathpunk how about finding the pair of homophones of maximum Levenshtein distance?
@Electrokittie water can't be compressed. So if you push one end of a full pipe, the force is passsed right through to the other end
@pkrautz I've looked at it before, and I find it a bit hard to read/parse.
@pkrautz the low-contrast colour scheme is my main issue. If you could get logos or author photos for the blogs, that would help too
Reminder: Newcastle @MathsJam is tomorrow, 7pm, the Charles Grey, Monument. Puzzles, conjectures, weak jokes, etc.
@jjsanderson @elinoroberts will either of you be at mathsjam tomorrow?
@pkrautz ummm... Technology? Eg MathJax, eassessment. Also: my blog ;)
@pkrautz could ask for pics from your featured picks each week, and build up that way. Most people will happily send their own in anyway
@mattybeardsmith @Electrokittie yes, I gave a simplistic explanation. Air works, but less efficient because it's compressible
At a tapas restaurant with unadventurous eaters. Somebody save me from myself before I NOMNOMNOMNOM everything
I have a square number of followers, but that doesn't mean my followers are square! (some of them really are though, and that's ok)
@mathsinthecity STOP THE PRESSES! A colleague has discovered the millennium bridge is neither catenary nor parabola, but something inbetween
@mathsinthecity will investigate. And, I realised today that there's a polygon hiding in plain sight in the city centre davidhamilton.me.uk/photo_6343183.…
@AdamJackzon that makes a completely unbalanced sleepytime top trumps card. Natty jimjams, out of 10?

I've written up what we did at last night's @MathsJam: checkmyworking.com/2011/10/newcas…
does anyone want to live in Tynemouth with me? I've had enough of my awful landlord.
whoever's giving the young women of Tynemouth all these elocution lessons is doing a bad job.
"Term rewriting and all that" is already 300 pages long but it could really do with having more words in it
@standupmaths "the first one after nought"
@Amy1306 it's a terrible feeling, getting the wrong thing out of a vending machine
@trackinthebox someone said that flight facilities could tour indefinitely just playing Crave You and Foreign Language. I don't disagree.
Stuck in the university library behind an apparently racist router that won't load anything from the US
@peterrowlett I've seen one somewhere! I can't remember where though
why did I offer to convert these word documents to HTML+MathJax? They're full of maths! I might go bogo crazy raaaa woooo
overriding corporate CSS so it looks half-decent. Is "div.actualContentAreaNotGIFCornerImagesYouCompleteMorons" too long for a classname?
I think I might find myself on Monday morning in the corporate web dev team's office screaming obscenities on the topic of semantic markup
@brittneybean it's at a negative co-ordinate relative on that scale - more like Michael Bay's 2005 yawnsplosion "The Island"
the first year engineering Maths-Aid worksheets are finally making their way on to the web. ncl.ac.uk/students/maths… Thoughts, anybody?
@brittneybean before I found she was giving them the father's surname, I thought "Airy" would have been a better adjective
@MathsJam I've had a good response to my recap blog post about this month's MathsJam. Is anyone else writing up other meetings?
draw commutative diagrams with MathJax! Incredible! homepage.mac.com/oasis/xyjax.ht…
@peterrowlett @Samuel_Hansen eps when you leave it til last 10 minutes to mention me are THE WORST. I spend 30 minutes thinking I've won!
@Electrokittie Pug Whisperer?
I now have 200 followers, thanks to @edbradshaw!
@gingerbeardman I think you'll find it's Lykke Li who sounds like a poor Yukimi Nagano
@NewcastleCC is there a picture of the baby alpaca?
@jamesgrime do you mean, "is it possible to do that with a shorter sequence than just listing them all"?
@haggismaths just googled dodecahedron colourings and your blackboards blog is on the first page! PS I have a blackboard pic if you need one
@peterrowlett glad to hear it! Of course, if you're immobile, this is the perfect occasion to gab on skype about eassessment
@benkenyon aren't unemployed kids just kids?
"this ticket allows travel on any permitted route" is not a good description of which routes are permitted
WHY DOES THE PRICE OF ANYTIME TICKETS CHANGE THROUGHOUT THE DAY?!!!
WHY DO YOU HAVE TO SAY WHICH STATION YOU'LL COLLECT YOUR TICKETS FROM?!!!!!!!!
@Gelada have you ever met anybody from bielefeld?
@Gelada oh no! the conspiracy has got you!
@Gelada en.m.wikipedia.org/wiki/Bielefeld…
I'm in the greggs concept shop. It's the same price as Costa and I can't see any pasties, so what's the concept?

@GreyAlien this is why I don't like tau. e^(i*pi)=-1 is much more interesting
looking at my referrer stats, I find I'm the second google hit for "pure math blog". I can only apologise
@standupmaths the childish acronyms are why I can't take American legislature properly. Then there's all the other stuff too.
@mathshistory wow, what a top chap!
I was ready to get angry about slavery, but this made me angry about percentages instead: slaveryfootprint.org/survey/#whats_… Ratios! Not Percentages!
you could say, that site made me DISPROPORTIONATELY angry!

@Bishnavitch battle lines have been drawn
@RANIELDANSON Stressed Eric. He's due a comeback
@mathsinthecity and it was 10 when I was born, but I still owned one. If it was the other way round, *then* we'd be in trouble!
has anyone else noticed that every Hermann Tilke track has basically the same final corner?
@PumphreysMaths I have an answer but is there some reasoning beyond informed guessing? n^2-80.5n needs to be +ve, so pick n=81...

@MathsJam could we link to my NCL recap post on the mathsjam.com page for NCL? Many people have said they don't get what MathsJam is
@Samuel_Hansen ahh man! Two days layer and I would've said yes
@Samuel_Hansen I'm in London 18th-20th - Acme Science team meeting/dinner?
@Samuel_Hansen Newcastle. I will be amazed if you go anywhere near
got to the point where I hate my code and want to rewrite it all. Why was I so stupid in the past? Why couldn't I be more like me now, then?
so this weekend, basically every girl I had a crush on between the ages of 5 and 13 got married.
@ColinTheMathmo I've written a thingy to look at probability of being a REPP: checkmyworking.com/misc/repps/ what am I looking at?
@ColinTheMathmo actually, I've got my maths hilariously wrong. Wait a mo while I sort it
@ColinTheMathmo I've fixed it now, but it's considerably less enlightening than I thought it would be

@jjsanderson no!!! They are my special treat!
down with "in the sequel..."! mathoverflow.net/questions/3373…
@ColinTheMathmo just looked at my REPPs thing in IE and it was completely broken. Works now, but styling is knacked. Do you use IE?
@ColinTheMathmo ah! Does it work now? I'm using some brand-new javascript bits which needed polyfilling for old browsers.
@ColinTheMathmo ah jeesh, I forgot to upload the correct-maths version yesterday, and now I'm at work. I call an end to the whole endeavour!
@haggismaths that Chalk paper is going straight in my Interesting Esoterica collection. A gripping read!

@pkrautz I'm writing another post for acme science. I never got your point re mathblogging - does it supersede my posts, or what?
@pkrautz ah! Klaro.
@pkrautz maybe whoever's in charge of writing the email also has a power cut?
while @Samuel_Hansen is doing a Tom Hanks in the airports of the western world I snuck into his blog and did a post: acmescience.com/mathematics/13…
Loneliest dinner. twitpic.com/79xqzj
you'd better believe I'm eating a box curry for one. I'm still available, ladies.

second time out: "The Internet Maths Aperiodical - temporarily a periodical" on @acmescience acmescience.com/mathematics/13…
@A_Hiccup whoops, sent that from the mathsjam account and not my own. Sorry, other @MathsJam people!
@A_Hiccup I'm not involved in the postcards. Did you post your code somewhere?
@alexbellos three thousand-twelve? Unsatisfactorily small, but I can't think of any more tricks
New flat happy hooray!
@ThomasEWoolley well done! Did you see my last Aperiodical post about the rabbits? Your next job could be King of Rabbit Husbandry
@alexbellos could a Southerner get away with 'fifty-four fousand firteen'? Not sure if any American dialects do this so wording is a bit odd

Ha WHAT! In a facebook ad, GCHQ are offering £25,4446 "+ benefits". Is the Official Secrets Act a benefit? I make almost that much anyway.
@peterrowlett shameless fishing for easy laughs on your podcast
@MissJKDarcy is that a good reason to take a job?
@RANIELDANSON anything good in the paper today?
@standupmaths Are you still planning on coming to NCL MathsJam this month? Also: you're still not following me so I can't DM you :(
@stecks so glad you agree! It really is a joy
@JSlayerUK if that isn't a trendy pop-up shop idea I don't know what is
@fadesingh @Gelada as seen previously on my arty maths blog: artymaths.tumblr.com

@jjsanderson is the M62 the one that goes reaally high up and gets loads of fog? I need to drive on it tomorrow and am worried
Setting off for @MathsJam!
It is an unseasonably warm day at #mathsjam. Will any activities be outside?
@MathsJam could we get urls from those people who put their hands up saying they have maths sites/blogs in my talk?
@peterrowlett are you recording now?
@cyberrhetoric thanks! Do you still live in the region?
@simenspurkland go for it. Can't hurt.
Fairly sure nobody has that name. #mathsjam

@standupmaths Whisky Galois #drammaths
@standupmaths did you like Whiskey Galois? I was so pleased I faved myself. It's a pun in a pun in a deft cultural reference! #megaproud
@peterrowlett @mathsinthecity which is why the original, "there are only three kinds of people..." is, though less clever, a better joke
@JSlayerUK I'm conflicted. While Zwarte Piet defo has racist roots, there is a cartoonish joy that I wish we could enjoy without the nasty
@JSlayerUK because, entirely on its own merits, a dude in a clown suit following Santa is excellent. The rest is what ruins it.
@Electrokittie just enjoy it.
@Samuel_Hansen I've just listened to #mathmaths 73. I declare total victory!
@Samuel_Hansen Food episode? I can't even think what that is the auto-correction of
@Samuel_Hansen ahh. BEST EPISODE
@Samuel_Hansen maaaaybe.
I've written a blog post with links to go with the talk I gave at #mathsjam: checkmyworking.com/2011/11/writin…
this won't fit on my arty maths blog but it is fun: knstrct.com/2011/11/14/sol…
maybe I need another blog called "I tried to get your maths into my art." Here's another: mathcraft.wonderhowto.com/corkboard/math…
@ColinTGraham hmmm... I'm not keen on equation editors like that. It's hard to tell where your cursor will go after keypresses.
Newcastle MathsJam is seven days in the future, on the 22nd. @standupmaths will be joining us. Charles Grey pub, Monument, 7pm, as per.
@jjsanderson that has reminded me to check up on my man who is meant to be watching progress bars
@allysonlister send an email to newcastle@mathsjam.com if you'd like to get a reminder before MathsJams in future months
@nulibsage where and when?
@nulibsage that's cutting it a bit close. I have to finish my hot choc then haggle with my old landlord before heading in to town
@nulibsage yes please. Though arguably, since this convo is taking place on twitter, I might not need them? :)
@nulibsage I'll tell you what you can do though: plug Newcastle MathsJam, 7pm next Tuesday at the Charles Grey mathsjam.com/index.php?cont…
@nulibsage muchos gracias!
Why is it that feeling tired, hot or angry all feel the same to me? Even when I know I'm only 1 of the above, my brain triggers the other 2

Co-author has manually inserted linebreaks at the end of every line! Going to kill somebody!
or maybe it was Google Docs. Will revise earlier vow: going to kill someTHING.
@Bishnavitch @enoFsamohT I had a dream about Howman last night. Seems now it was a prophetic vision.
@stecks maybe their maths-checker sent a comment pointing out wrong numbers, which they misinterpreted as a disclaimer
@stecks and the right-hand column header says "Sodium + chloride"!
Crewe and Milton Keynes in the same week?! Truly this is the life I always dreamed of.
@mattybeardsmith I had always assumed it was slurry in real life, cleaned up to look like whatever food it's meant to be in post

A church! Have they not looked outside? There is no God. #miltonkeynes
You know those programs that stitch together panoramas by recognising unique features in multiple photos? They would fail in #miltonkeynes
Time and space have lost all meaning in #miltonkeynes. 1 dimension of despair and 3 of boredom are the axes I travel along now.
#miltonkeynes: like being in a coma but there's nothing doctors can do to get you out of it
A desperate man is taking photos of the buildings around him. Maybe when they're developed, he kids himself, I'll see something interesting
I just farted. The people walking by are stopping to thank me for the sensory stimulation. #miltonkeynes
I think I'm drinking coffee! What is 'chocamiento'?
Loitering on the street, drinking a frijj. I'm as tough as any Londoner.
@jcoglan they're not blocking it for me
The horniman museum is really lovely!
Compendia in Greenwich market sells mathematical games, including Set! Extensive dice collection, but not @jamesgrime's non-transitive ones
@jamesgrime's judging by the prices of other dice, looks like they turn a meaty profit. You should get a piece of that!
How is this train so hot?
@jamesgrime actually, how come non-transitive dice weren't invented as a cracker toy by Victorians? How old is the three-dice set?

Schokozeit ist jetzt
@ColinTheMathmo there's a bit of an implication of cynicism there, which I don't think is warranted
@ColinTheMathmo take it up with him. Probably he likes the discussion, but isn't OK in his head with the idea of ill-posed questions
@ColinTheMathmo man twitter is bad for getting across subtle points! Do you get what I meant?
Mega-merge seems to have worked, after very little fiddling. I am extremely wary.
one of my bills has an account number "42924262". Very weirdly almost-symmetric. It doesn't feel like a real account number.
oh COME ON, North Tyneside Council! Your Brokenola website is plumbing new depths - screenr.com/qLqs
@tynesidecinema that clashes with MathsJam! There are not enough days in the week for me to be as geeky as I want to be :(
@tynesidecinema well actually, the reason I'm interested in knitting club is that I have a book called "making mathematics with needlework"
@elinoroberts oh no! I apparently can't hear it at my new flat. This makes me sad
This woman has a face like that kind of dog that people who look like her own.
oh man I thought I was still on for an early start! How is it eleven o'clock? This bedroom needs more natural light in it.
Top maths fact: 85% of mathematicians who can solve Rubik's cube only learnt it because they felt it was expected of them.
@MathsJam was last night our last meeting of 2001? Are any crazy souls going to be MathsJamming on the 23rd?
@MathsJam of course I meant 2011...
@MathsJam heuff! No idea what part of my calendar I was looking at
@standupmaths that dice shop: compendia.co.uk . Not sure about business acumen but they definitely know their way round a profit margin
@jamesgrime you have exceeded your bandwidth limit! Your website is down.
@E_I_W was the circles-inscribed-in-circles puzzle one of yours? Where did you get it from?
@standupmaths could I put copies of your pics from last night on my site? I'm writing a blog post and twitpic doesn't allow hotlinking
I've blogged what happened at last night's Newcastle @MathsJam. Summary: too much! I need a lie down now.
not one of the shelves in this kitchen is tall enough to accommodate a box of shreddies. How annoying.
@vikkiiom second last Tuesday of the month, so the 20th. Not sure there will be many people around!

@mike_geogebra your picture is rotating! Has it always done that?
time for a bacon, egg and everything else sandwich
@IanMulvany I've made something similar, takenot.es but it exports HTML or LaTeX and does some clever things with embedding media
all I want is an office chair that works on ratchets instead of stupid failo pneumatics
@aperfect is thanksgiving the same day every year?
@standupmaths excellent timing. I've just finished some Hard Maths and will listen to that while my brainbox cools down
@aperfect NNN, where NNN is the unicode.
@standupmaths you make a lot of references to googling and things, so it would be nice if there were show notes in the post
@mathsinthecity and tweets! What have you got planned?
@peterrowlett I've read a few bits. The maths video aggregating bit looked interesting, but no URL to the actual site :(
@peterrowlett mm. Quite.
@jimalkhalili contrapositive is true but not converse! Descartes happily makes his way home

@ColinTheMathmo "is irrational" is a negative statement, so what would a direct proof look like?
@ColinTheMathmo maybe sqrt(2) is irrational is a big fact
@standupmaths is this all leading up to a bit of viral advertising for @jamesgrime's dice? I think you've got a knack for business after all
@ColinTheMathmo thanks for plugging my post. What are you basing the assessment of popularity on? Doesn't look like you got many RTs
@Electrokittie I'd always assumed it only stayed open because the scientists at the Centre for Life were doing an experiment
@ColinTheMathmo hah, well I haven't had that many hits, according to wordpress!
@ColinTheMathmo ahh, I thought you'd only posted it today. Mystery solved, time for drinkies
Both tyne tunnels are open! When did that happen?
if you make mathsy art from now on, it needs to be at least as good as this: artymaths.tumblr.com/post/133049762…

@CloudoidLtd I did not! It has occasional DNS issues, maybe that was it?
I only discovered this halfway through, but it's a brilliant french sketch show on iplayer: bbc.co.uk/iplayer/episod…
@haggismaths this really short explanation of Godel might also be helpful: blog.plover.com/math/Gdl-Smull…
aaaaa the government is spending the pension fund on motorways. I am going to die cold and alone in an underpass!
how did this email, which even has the phrase "penis growth" in the title, get past my spam filter? Bayes is tutting at me.
@Samuel_Hansen bulkhead seat!
@aperfect date on the article?
@standupmaths no idea, but mad props for starting at CLUE-0. End nullophobia now!
@standupmaths BLETCHLEY PARK!
@standupmaths and here's the original, currently in the same room as the Bombe flickr.com/photos/christi…
@Electrokittie who would read it?
@Electrokittie that is a terrible, terrible idea
@Electrokittie what's she done now?
I'm hungry but there is no food in the flat. I'd better do my big shop then. #goingtobepoorsoon
@standupmaths oh. ho. ho.
@standupmaths great video! David, the chap who told me the puzzle, says there's a similar one in the new Prof Layton game on the DS
@haggismaths I'd be interested to see what you produce, if possible
@haggismaths I'm just after your impressions from using maple TA, really. E-assessment is my job.
@TraineeGeek what kind of phone is it?
@MathsBusking I've been trying the 27-card trick with other bases (and numbers of cards, obvs) and it works without modification
@TraineeGeek if you get a replacement then get an android phone - contacts are stored by google!
@jamesgrime @peterrowlett another group theorist! Are group theorists more likely to engage in outreach than other pure disciplines?
@aperfect early adopters gonna adopt early
@standupmaths your video has prompted a considerable no. of people finding my blog through googling for the solution to the princess puzzle
@MMPmaths great resources! Good that you use MathJax, but did you know JSXGraph does interactive Lotka-Volterra graphs? jsxgraph.uni-bayreuth.de/wiki/index.php…
@standupmaths ooh, I'd better edit out the incorrect solution then!
@plusmathsorg "50 mathematical ideas you really need to know" is excellent
the personal appeals on wikipedia have taught me that wiki editors look like exactly the awful kind of people I always imagined they were
@plusmathsorg I can provide an extensive list of pop maths books to avoid as well, if that would help
@plusmathsorg I disagree about Godel, Escher, Bach - far too long and complicated to qualify as "popular maths"
"These guys don't do anything. Kill them." - some brutal mathematics being laid down in this talk.
@jcoglan I am just itching to break out the #unhelpfulneckbeardadvice tag.

@RANIELDANSON it's people followed by people you follow. So, only advice, get better friends
top fact: any word beginning with 'gr' is still a word when you replace the 'gr' with 'h' - grip -> hip; grand -> hand; grunt -> hunt, etc.
grow -> how; ground -> hound; grumble -> humble; I think I'm on to something here
@karenshancock is this a cry for help? I'm going to intervene: if you eat too much bacon, eventually you will not like bacon any more
@dmh10 oh no! You've inadvertently disproved the rule! Hab is not a word!
ok everybody: I've done some Python, and the best prefix-swapping pair is 'no' -> 'u', with 4245 words.

@JSlayerUK my HTC has an option under Settings -> Language and Keyboard. Does yours not?
@JSlayerUK oh dear! I am out of unhelpful ideas
I just saw a shooting star! It made me happy :)
@peterrowlett @stecks @Samuel_Hansen :< I'm a real boy!
@standupmaths I think that makes an APR of 214%. Depressing.
The only time I experience regret is when I just miss a train and wonder whether everything I put in my bag before leaving needs to be there
@brittneybean @tomnewton or how about imtotallyoverthesecleverspanishdomainnam.es
@peterrowlett his birthday always wooshes straight by in the Advent excitement so I'm never sure exactly what day it is

I've made an interactive version of the princess-in-a-castle puzzle: checkmyworking.com/misc/princess-… (cc @standupmaths)
and now I realise why I stayed up so late: I queued up four hours of classic Coltrane before I started programming. Euf.
yesterday, for an hour and a bit, my supervisor said nothing, but I left his office with a solution to my problem. #maybetelepathy

@standupmaths searching for CC-licensed images of princesses just made me depressed

@PumphreysMaths what kind of rules about names of numbers will you impose? Because I could say "the biggest anyone else says, plus one"

Jimmy Wales: "If all reading this give £3 a month we would only have to fundraise one day a year" - I don't even know what that *could* mean
@stecks that makes sense.
@jjsanderson is the problem that they have soft chocolate centres or that nothing in the bag seems to be a woodland creature?
Somebody should make another game like Sub Culture

@gingerbeardman could you make the close button on the Wire Hang Redux window work? It's BMax, isn't it?

@jcoglan I'm going to tell you something, and your mind will reject it at first, but it is true: BLT pizza is amazing.
@ColinTheMathmo draw a view cone coming out of the eye. Draw arcs close and far. Object covers more of close arc than far one.
@ColinTheMathmo crumb! Take the opportunity to explain how the eye works as well. I'm intrigued to see what more direct explanation there is
@peterrowlett @ColinTheMathmo @ben_nuttall for example: flickr.com/photos/christi…

I've just sent out the email for December's Newcastle @MathsJam. It's next Tuesday, the 20th, in the Charles Grey pub
@alexbellos that is genuinely amazing
well done to @plusmathsorg for explaining the Higgs stuff in terms I can understand
@alexbellos a google scholar search for the cyrillic spelling returns a few: scholar.google.co.uk/scholar?hl=en&…
@alexbellos ah, did you mean has anyone used one of his papers in the process of actual research?
@alexbellos oh well, can't help you there

@GhostMutt it's really responsive and driving is if anything easier than the pc version. This is on my asus transformer though

Oaths and blasphemies! This email inviting all Newcastle postgrads to a trip out is 2MB purely because the sender used CC, not BCC!

I can't decide who released a more disappointing second album this year: Justice or Thomas Tantrum
@aperfect no, you are wrong. None of the brooding menace or jumpity tempo of the first one
@AdrenalGBR I have an answer. Do you want it now, or at mathsjam?
@AdrenalGBR was it a problem you thought up or did you see it somewhere?

@ColinTheMathmo nice post, but MathJax would make it nicer! In addition, your twitter button image is missing
@ColinTGraham because you can find them by searching for @MathsJam. People who don't want to see our tweets can just not follow us
@ColinTheMathmo really really? Email me, you're almost certainly doing something wrong. They work very hard on compatibility.
@ColinTheMathmo doesn't render at all or renders incorrectly? If latter, you might have conflicting fonts in your cache, eg old STIX fonts
@peterrowlett tee-hee! they were both me!
@peterrowlett oh, and could you please make it look like I didn't misspell "Marcel Marceau"? I'd like to blame autocorrect.
@stecks you are doing a wonderful thing. I haven't had a chocolate advent calendar this year so YuleTube has put a smile on my face each day
@peterrowlett yes, I had a v slight change of mind. Young diagrams still need a little bit of explanation, so both statements are correct ;)
@stecks I failed to print out your eve-eve-eve-eve-etc calendar. That tickled me hugely.
@ColinTheMathmo is there a reason your intervals are closed, not open?
@ColinTheMathmo is website@solipsys.co.uk a correct email address for you? I sent you an email and thought you might reply to that instead

@EliotBall yep
@enchamade I mean in the source .tex, not the compiled document
"Enthusiastic network marketer - born again pagan - I'm collecting cashback with Cashbackcard - are you?" - worst twitter bio? I felt sick.
@peterrowlett the "born again pagan" bit worries - another symptom of poor critical thinking, or of a willingness to do anything for money?
@ellenirites I beg to differ: it was quite a popular middle name in 1911, viz. 1911census.co.uk/search/results…

@Electrokittie snaggly frown :<
similarly alluring addresses are available to sufficiently-hot mathematicians (contrapositive: not having one => not a hot mathematician)
@Electrokittie well, I didn't need to see that! Yeesh.
@ColinTheMathmo of course I assume that, given the opportunity to have such a winning address, any hot mathematician will accept instantly
@Electrokittie second-class Oxford degree. Borderline.
@ColinTheMathmo don't quite understand what you want, so have you seen traintimes.org.uk? maybe ask him where he gets his data?

@peterrowlett if you're not going to link to those dancers I will in the Aperiodical

@peterrowlett I assumed @stecks would see that tweet, plus anyone else who's had enquiries. She knows how to contact me!
@peterrowlett patience, Rowlett! It's the morning

@RANIELDANSON that's the kind of completely equivocal recommendation I can really appreciate!
@peterrowlett @stecks ok, I've added a bit to the bio saying to email manchester@mathsjam.com or tweet @MathsJam

@peterrowlett 80 news: my nana was 80 yesterday. She'd love a math/maths shoutout
Just been told the place for nana's 80th party today has a flock of alpacas in the grounds. Considerably more excited now.
@peterrowlett @Samuel_Hansen to be very clear: I'm requesting a cp-ancestor mention. My policy on hearing my own name remains unchanged
@elinoroberts some of these puns are pretty hock-neyed
@jcoglan shave your moustache first, then sideburns, and beard last. #unhelpfulneckbeardadvice
@jcoglan it's as if I spent the last year setting that joke up!
Have found myself wedged under a table. Need to move out without pushing the table. Curse you, Newton!!!
@Samuel_Hansen you scoundrel! For a few glorious moments I thought you were both genuinely trying to avoid mentioning me.
@elinoroberts ohh, don't you find that place a little bit creepy?
Just passed an Austrian tourbus emblazoned with the slogan "Beat the Street". Do you think they meant "hit the road"?
Whenever I see a full moon partially obscured by clouds, only four words and a guitar riff come to mind: TEENAGE! MUTANT! NINJA! TURTLES!
@Rosalot disagree. They were ninjas more than heroes, and the tory-era ban on nunchuks in the media was so ridiculous of won't perpetuate it
@christianp @Rosalot *I* won't perpetuate it
@pkrautz you now have 100 followers. Congratulations!
@Rosalot there was a moral panic about ninjas, hence "hero turtles". All the really cool kids knew the real name. en.wikipedia.org/wiki/Teenage_M…
@Rosalot PS my full signature book from universal studios, even with scary Casey Jones, hints that I am a bugger fan than you
@Rosalot ha! Bigger fan! Autocomplete hates me twice!

I hope this was worthwhile
@Electrokittie what were you showing us?
you're damn right the LaTeX I used in my tweet earlier gets properly typeset on my blog
@Electrokittie hahaha that is excellent!

@Samuel_Hansen can you get on Skype? Is it a reasonable time where you are?
@peterrowlett an interesting email should currently be at the top of your inbox
@stecks good point, I'll send it to you too.
@stecks by publicly twittering peter, I was actually prompting people like you to remind me of should have included them
I do wish my phone would stop rewriting 'I' to 'of'
@peterrowlett as far as I'm concerned, that other email was responded to at mathsjam. I wouldn't mind if you *do* reply to it though...

@standupmaths best you can do is 379. 379,397,739,9638 prime but 793, 973 not. Answers with repeated digits: 113, 199
@christianp @standupmaths well of course I meant 963 not 9638
my 1177th prime birthday is the day after my 26th real birthday! Double festivities!
@christianp and I should read my computer better: 149 also has 4 prime permutations

I'm an evil genius: I have decided to make a rubik's cube with ratchets in, so each face can only turn one way
@EliotBall yes, but the look on someone's face when they first encounter it will be priceless
@EliotBall or: can you think of a set of interlocking ratchets that restrict the number of positions the cube can be in?

@Samuel_Hansen aww, you deleted the crazy man's comment on the blog :(
@Samuel_Hansen is this a network q: how long should it take a service to have most things you'd want on it? Eg wikipedia, youtube, the web
@Samuel_Hansen indeed. It feels like something that would be fun to work out a methodology for.
Never change, Nana.

I've gone a bit silly with old age.
@ellenirites you look wide-awake to me
@Rosalot would you like a lecture on queuing theory? It's very interesting, I could go on for ages
@Rosalot there is an optimum queue length they want to maintain at all times. So they change the staff levels as incoming call rate changes
@standupmaths @TimandraHarknes you're not going above Harrogate? I was about to drum up some PhDs to see you!
@TimandraHarknes @standupmaths one of the aforementioned PhDs is also a standup. I will enquire.
I just thought to try j/k to scroll through tweets. It's a @Christiansmas miracle!
@Andrew_Taylor @standupmaths @pixie359 well, @peterrowlett did basically that in his Travels in a Mathematical World podcast
@pixie359 but he got his facts from numbergossip. So listen to his podcasts anyway, just not for this reason.
I'm going to sell savoury pastries under the name Quiche Thegwin.

@Nathan1123 the thing I'm making has to support IE
@Nathan1123 your tweet arrived simultaneously with me fixing the bug. Hooray for a coincidence!
@Nathan1123 I've been working on this for two years. This is just the latest bug.

@standupmaths my activities are not uniformly distributed throughout the year
reading wikipedia like a boss. Finally A-Level French is paying off!
@pkrautz (@peterrowlett @Samuel_Hansen) do one this week. I still haven't "hung out", so I'll look in. Why math/maths, not your own thing?

@trackinthebox when you redesign, could there be a way of listening to all the last week's tracks without clicking between pages?

@AdrenalGBR go on then. Are you sure it's difficult?
@AdrenalGBR oof, that's not a programming problem, I don't think. Is it OK if I retweet from the MathsJam account?
@AdrenalGBR also, I want to fix your notation but I'm doing something else at the moment

@daveowhite @mathsinthecity I would replace my Ampelmann umbrella with a Maths Dave one in an instant
@skrivr I've just got an invitation and started a blog. Page loads and sync seems to be failing. Are you under heavy load?
@skrivr ok. Is there any reason why that would make the settings pages or even the 404 page not load fully?
@skrivr and does the fact you know that mean you can look in my entire dropbox folder?
@acmescience I did not know you were doing this! It alone has made relatively prime worth the money.
@acmescience then I'm glad I gave you so little money. I got an excellent deal!
@stevieb How have we not bumped into each other at conferences? Thought you got a job after your MMath, had no idea you were doing research
@skrivr yes, it looks like it's working now, thanks
@HilariousCow this just in: women also shave.
@stevieb I'm doing more jobs than would fit in a tweet, plus a PhD on group theory / computability
@stevieb somewhere in the middle. I'm self-funding and part-time, so no idea when I'll finish
@mike_geogebra @davidobrador shapecatcher.com lets you draw the character you're after.
@danaernst skrivr.com/christianp/ it's very flakey, which is why it's still in beta, I suppose.
@danaernst I don't really have a need for it, because I've got my own proper wordpress blog and takenot.es for quick notes
@danaernst yes, I have christianperfect.calepin.co - I just signed up to help Theron get MathJax going, really
@danaernst checkmyworking.com . My workflow is to write stuff on takenot.es (instant TeX preview!) then copy it straight into wordpress

@EliotBall the Chrome developer tools are very good
@EliotBall good stuff. Do you know about prototypes in javascript?
@EliotBall it's just a good idea to declare methods in the prototype rather than in the constructor

@brittneybean wasn't even the audio. I just wanted to middle-click the provider's logo to see who they were.
@EliotBall I've just added some explanation at the top of the file
I look at the publications list of someone like Zeilberger or Svante Janson and I think, what's the point. Let them discover all the facts.
why is copying text from PDFs such a hassle? Can't the information about, for example, where the spaces between words are, be kept?
@Andrew_Taylor It's a problem pretty much unique to PDFs. Most of these files are generated by LaTeX, from the looks of them.
@Andrew_Taylor I *think* that the reader program has to infer the presence of spaces from the positions of glyphs on the page.
@Andrew_Taylor the problem is that a pdf is just a list of where to put symbols on a page, not a coherent representation of the text
@stecks could the link to my MathsJam posts on the Newcastle MathsJam page be changed to the category listing? checkmyworking.com/category/maths…
@christianp @stecks actually, I've realised that category has non-recap posts in it. This one, please: checkmyworking.com/category/maths…

@acmescience do you know that none of the links from the C&P Classic RSS feed work?
@CloudoidLtd I don't think I have! You should post a comment with a link to it.

@jjsanderson should've stayed in Tynemouth! I got out just as it was reaching its peak.
@Samuel_Hansen can I just say what an excellent job you did on the podcast this week, in my opinion.
@JSlayerUK BECAUSE POOR PEOPLE ARE GETTING ALL THE MONEY DON'T YOU GET IT
@acmescience haha, that's an excellent idea
to do a global find and replace on a file and have it compile correctly immediately afterwards is a sublime joy.
@Samuel_Hansen that's a mighty short post on your blog there, Samuel. Ephemeral, I'd even go so far as to say. Not that it's a bad post...
today's grand insight: $x - y = x + (-y)$. I'm a good PhD student.
@ellenirites Old age is pretty fun. You can walk into a place like you know what you're doing with your life and nobody calls you out on it.
@standupmaths please, get some MathJax on that blog!
@standupmaths also, use the <code> tag (the wordpress editor has a button for it) around your Python code so indentation is preserved
@standupmaths & finally, wp-footnotes is a good plugin. It makes footnotes which link back to the relevant bit of text. elvery.net/drzax/wordpres…
@standupmaths I can email you the code if you'd like. It literally takes two minutes to paste it into your header file from the admin page.
@standupmaths also, @danaernst and others are planning a mailing list for mathematicians with WP blogs. I'll tweet it when it exists.
@Gelada @standupmaths @danaernst well that sounds like we have a quorum. @pkrautz is keen as well.
@mattybeardsmith how many people work there? Not sure you've spotted a trend there

@pkrautz yep

@peterrowlett you'd better check your registration status!
Off for a cheeky Micky D's before @MathsJam
@pkrautz they've reverted to the old one, so depending on cookies and caches, it'll either appear or not for a while
@stecks are you getting much done in Manchester? A write-up of our night would just be, "we played with Lominoes then went home"
@peterrowlett @MathsJam or it's a double-bluff, and the answer is no for a surprising reason
too many computer scientists named Philip.
@ellenirites @sadiestrong I will eat something similar! Good idea!
I took 7 pages of notes at last night's MathsJam. Durham students are too keen.

@ellenirites @RANIELDANSON you're both wrong. "Yourself" as a subject pronoun makes me very very angry indeed.

@ellenirites @ranieldanson "Would yourself like anything else?"

why is nobody using something TeX-ish, i.e. a macro language with minimal syntax, as a template language for the web?
man, I'd probably hate heroin. The noises I make when I haven't had any chocolate in a while are bad enough.
@EliotBall no, it doesn't have macros
@EliotBall macros are new commands you can define in the text to abstract out common patterns.
@EliotBall yes, well, I was asking why nobody had done that
@EliotBall the usual reasons people want templating languages

Not sure why I misread Leonhard Pfeifer as Leonhard Euler but that's the most excited I've been about a John Lewis window display in a while
@stecks look at the end of this video youtube.com/watch?feature=… - I'd love to see them do more of those orbits you talked about at mathsjam
@daveowhite well, the argument could be made that Google's IPO changed how they work considerably
@ben_nuttall the Euler characteristic is actually a design motif
I dislike bug reports written in the passive voice.

@PeterMolydeux you're just repeating plots from Round the Twist now
Decided I was going to take three steps at once but that thought didn't get down to my legs in time.
@peterrowlett I'm perfectly fine. Thanks to my height, I had enough thinking time to rectify the mistake
and my blog is ill again :(
@RANIELDANSON one day your loyal #FFing of me every week will be rewarded. Not today, though.
@peterrowlett so should #gausslies be true? @gaussfacts are mainly false.
@standupmaths have you been in one of those ones that moves continuously and loops round at the top? They scare me.
I've got a really quite enormous lumpen spot in that little crevice behind my ear. Worried it's like a boll weevil or something.
@Electrokittie hah, those are totally Auntie Sheila shoes. Aunties of other names need not apply.

@chaosdynamics that's hilarious. Remind me never to visit Boston or I might get fisticuffsome.
@stecks you're in Newcastle tomorrow, yes? Coffee and Lominoes?
@stecks as you're tourists, I suggest the Baltic. Alternatively, heading into town, there's Blakes or Cafe Royal

@mariondov pi is defined in terms of the properties it has. Series representations are often derived from trig functions with known values.
@mariondov but there now exists a formula for individual digits of pi without working out the previous ones, so calculations can be checked

@ellenirites we were having a discussion in the maths department about the practicality of storing soup in tupperware. I see where you stand
@ellenirites can't really remember, but empirical evidence of expected spillage was sought in the staff kitchen.
oh wow, the Proceedings of the FUN with Algorithms conference is treasure trove of excellent paper titles informatik.uni-trier.de/~ley/db/conf/f…
@ellenirites ah, but we were discussing it as a means of getting soup into work

@ben_nuttall Resources tab. Click on Frames -> (myfile.htm) -> myfile.htm. Tada!
@ben_nuttall oh no, that's only got new selectors in it.
@ben_nuttall though if you do make changes, the stylesheet in the resource tab is changed to reflect them, and the original is underneath
I'm editing a WordPress plugin. I hate PHP so much!
@ben_nuttall we're (some people you've heard of) collecting our individual blogs on one site. We've got a plugin which imports our posts...
@ben_nuttall but it needed changing so imported posts have the same publication date as the version on the original blog.

@mathsinthecity ooerr, tiny fame. @standupmaths has since informed me that London's circle line now has the same topological property :(
@mathsinthecity it's OK, this is how Science! is done. I'm going to start petitioning the council for a loop-the-loop in the Metro, though.
@mathsinthecity every time I go to IKEA, I forget to take a pic of the store map as an example of fractional dimension for the website
@mathsinthecity can you send an undergrad to take one? You have that kind of power, right?
it isn't even funny how long my body takes to recover from just walking for a couple of hours. Day 4...
@mathsinthecity incredible. And I've just discovered that google maps has enormous difficulty searching for ikea
there are only 18 IKEA shops in the whole UK?! I feel like a Byzantine discovering the Western Roman Empire collapsed 600 years ago.
@aperfect really though?
NVDA read "résumé" as "resume" and "resume" as "résumé". The mind boggles.
@enoFsamohT it's funny because now I'm thinking about you handling your own poo
@standupmaths is this a marginal utility of tea thing, or would the consumption of tea always have negative utility for you?
@jcsteh probably microsoft. I've been switching between the two
@jcsteh while I've got you - how well can NVDA read MathML?
@stecks @peterrowlett *cough* blog post please *cough*
@charliesgames how much fun maths was involved in the pathfinding? Could you do a mobius strip, for example?
@charliesgames so if they're diametrically opposite the player they won't move at all?
@charliesgames mobius strip: take a strip of paper. Put a twist in it. Glue two ends together.
@plusmathsorg have they really made a Turing machine? They've made two two-state FSAs, which aren't Turing-complete.
it is enormously annoying that codetalks.org has disappeared off the face of the internet

@peterrowlett make it so! It's pretty clear what it means.
@peterrowlett @xabl if it's good enough for @ColinTheMathmo it's good enough for me
@Electrokittie @Bishnavitch I'd love it if you changed "phenomena" to "phenomenon"
@xabl @peterrowlett @Gelada something something reappropriation of a derogatory term
@peterrowlett I'm classically trained in the art of rhetoric
@pkrautz Jan's mathsjam recap was the biggest yet checkmyworking.com/2012/02/newcas… and I wrote instructions on MathJax blogging checkmyworking.com/2012/01/how-to…
Been thinking hard all day. Squash and chocolate time.
@standupmaths I think some of your thief traffic is spilling over into the princess/castle problem and finding me on google for the solution
Mathmos, in particular analysts: is there any sensible definition of exponentiation on matrices that copes with real-valued exponents?
@ColinTheMathmo why have you got the band being stretched instantaneously in 1m increments? Ease of exposition, again?
@ColinTheMathmo Righto. We did the continuous one at NCL mathsjam, and we'd all forgotten how to spot an integrating factor problem.
@aperfect in CoffeeScript, whitespace is more significant than a raised eyebrow across a room
@pkrautz yeah, I was mainly teasing @peterrowlett

@standupmaths that gives me the idea of designing a (finite state? pushdown?) automaton which recognises all coffee orders
@Electrokittie my studies of Rose Byrne's features have not yet got below her chin, never mind her feet. Maybe others start from the bottom?
@Electrokittie I will conjecture that every part of her is good-looking, so maybe these people have a point.
@jcoglan ok, now you need to make an audio filter that tries to shift any singing towards an ethereal whispering of the words "WHAT AM I"

@MathsJam I've just noticed that Feb MathsJam coincides with pancake day? What are we to do? I take pancake day very seriously
@HilariousCow I have so many issues with the maths on that page. Mainly, the use of the percent sign when percentages are not being used

@Bishnavitch @Electrokittie @ellenirites @mattybeardsmith pancakes, my house, next Monday. Yes?
@outofthenorm2 I once had to do those calculations while driving a friend to the pizza place. Very hard to concentrate on the road.

@GhostMutt crumbs! Where have you read that?
@GhostMutt got a link? I need more context because it's a complicated topic
@GhostMutt ok, it's a bit of an unusual phrasing. "Limits" usually involve seeing what happens as a parameter tends to infinity.
@GhostMutt e.g. "the limit of 1/x as x tends to infinity" is 0 because the difference between 1/x and 0 gets smaller as x increases.
@GhostMutt on searching, "passage to the limit" seems to be popular with Russians. I would use "take the limit".
@GhostMutt Right. Because it doesn't settle on any one value.
hah, any paper downloaded from ScienceDirect is called "science.pdf". I want an exclamation mark in there!
also in re ScienceDirect: those poppy-uppy headers and footers with the 1000ms delay are really quite annoying.
time and motion planning is great except when it results in all the toilets in the building being cleaned at once

@Bishnavitch I'm ill! Apparently you called me 7 times. I love you too dude but after four you can assume I'm asleep.
@Bishnavitch I say no, I'm ill.

This is the most beautifully unhelpful diagrams I've ever seen in a maths textbook (Papy's "Groups")
I forgot to celebrate this book's 200th birthday! It is my oldest possession.
The things you find at the back of a bookshelf...
My original Creatures disc!
@peterrowlett I've been going through my bookshelves and found some cracking maths books, including one 201 years old (see tweets passim)
does it annoy anyone else when undergrads use "we" when they actually mean "I"? eg, "we can't solve this equation by the usual method"
in fact, I'm against the use of "we" pretty much anywhere outside a group report.
@NoelAnn yes, that would be better.
@peterrowlett yeah, but I don't like being implicated in my student's inadequacies
@peterrowlett @NoelAnn oh I did! I'm thinking of stuff like "we prove that ..."
@NoelAnn @peterrowlett at NCL we don't encourage anything - apart from occasional comments on homework, we give no training on writing maths

The milk bounced off my Frosties and on to the kitchen surface. So I'm not dyspraxic, I just live in a slapstick movie.
aww yisss that was my 4000th tweet and it was a good one!
@peterrowlett this withering satire considered too short or too inflammatory for second rate minds?
my mad scrolling problems were being caused by Facebook messenger. I am at a loss.
@ellenirites @Electrokittie nobody has ever been sectioned for hallucinating sausage dogs.
@standupmaths I'll blame the torygraph's copy editors for the fact question 1 asks you to find a pair of numbers which has 6 different sums
feel sort of bad for making @Electrokittie and @ellenirites flip pancakes against their will but those are the Rules of Pancakes
@peterrowlett I just checked and I'm coming up for five years on twitter! Has it even been around that long?
@madeupstats the average pancake is successfully flipped 0.8 times
@peterrowlett I hope you won't be liveblogging the crime I asked you to commit
@peterrowlett I don't know. Maybe ask those two guys with the camera?

@standupmaths I'm meeting my friend for dinner before mathsjam again if you'd like to join us
@standupmaths ah! 7 is when the pub stops serving food and when I need to be in the pub to start MathsJam. A conundrum!

@standupmaths is it OK if I use your photos from last night in my recap post?
@standupmaths couldn't hurt!
The letter H is the eighth letter and sounds a bit like "eight" when you say it. That's a little bit interesting.
argrgrw why is flickr upload on android+htc so rubbish?
I had so much fun at last night's @MathsJam that I've written it up straight away: checkmyworking.com/2012/02/newcas…
@ScienceFest could you slow down that slideshow on the front page a bit? I'm a fast reader and I struggled to keep up
@ellenirites I read that as #wetgirlproblems. Wasn't wrong.
Mad Abel is also a good solitaire game. I just finished a round with an enormous 9-card smash

This seagull is laughing like Jimmy Carr. Or, Jimmy Carr has climbed onto my neighbour's roof.
@Samuel_Hansen @peterrowlett you could pass the time by playing Desert Bus
@ellenirites proof that the adjective "inviting" doesn't always apply to invitations
@Samuel_Hansen we like all the same things, why must we be so far apart?
@peterrowlett @Samuel_Hansen series 2 finished on Five here just before series 3 finished in the US. Series 1 on dvd is highly recommended!
@peterrowlett don't confuse Sam further with the class system. Though I enjoy both the Archers and Archer, so where does that put me?
interesting - somebody's using pandoc to generate both scriptogr.am posts and LaTeX PDFs at the same time (with maths!) scriptogr.am/michaelt/post/…

@Gelada you got the spelling of 'noble' wrong in your post about being wrong.
@peterrowlett I'm torn. It's an admirable idea, but the execution is off. My thoughts don't fit in any of the things the survey asks.
@mathsinthecity I wouldn't know about that. Are they saving space on corridors so they can have more rooms? Does that make sense? Not sure.
@Andrew_Taylor is that snowman warm-blooded?
@peterrowlett what do you think are the chances of the new site having over 100 posts before it even starts?

@RANIELDANSON what happened to the sunshine warming your mood?
@pkrautz mega-gimmicky. They never say why a Penrose tiling is suitable. They certainly don't make use of aperiodicity.
@stecks @MathsJam does MK have a meeting-place or organiser? I'll update the map when they do
@outofthenorm2 according to who?
@pkrautz @Gelada yeah, opposite - think of how many ways you can put squares next to each other. Penrose tiles deliberately have fewer ways
@pkrautz @Gelada they're not using anywhere near enough tiles to get the Penrose effect - might as well use any shape with acute angles.
My blog recently passed 4000 all-time hits. That isn't very many!
@peterrowlett October last year. But I got a negligible number of hits before then.

@standupmaths I'm redoing it so the edges don't overlap, but that apparently takes FOREVER in graphviz. Maybe it'll be done when I get home
@walkingrandomly I think our economists use it. They use it because it's what they were taught and they are incurious beings
@outofthenorm2 good point
@Andrew_Taylor has one proposed to you?
@peterrowlett you're extremely close to your 8888th tweet. I suggest you make it something in Chinese about the virtues of palindromes

@outofthenorm2 my first year number theory lecturer used to do these tricks with stats from the end of Doom levels
@Electrokittie that is the opposite of what will happen
@outofthenorm2 oh! except he used continued fractions to get the answer a lot quicker
@jjsanderson @standupmaths I was amazed last night that I could still see it as far south as Peterlee
@daveowhite how bad? early 3dfx cards, or even PowerVR?
aw, this is a lovely idea goodgym.org
@daveowhite ouch. Suggest you use the Rumble Pak.
@E_I_W what time will you be in the pub?
@E_I_W excellent, that's when I finish at maths-aid. Mind if I join you?
@E_I_W well that sounds sinister!
@HilariousCow hey! That looks just like the original NPRQuake!
@E_I_W I'm on my way. There in five minutes
@peterrowlett almost exclusively wikipedia. Mathworld when I want a second opinion
@Gelada @haggismaths is this inverse kinematics + control theory?
@peterrowlett @stecks hooray! The site that doesn't exist yet has 100 posts. I'm itching to get started.
@Gelada @haggismaths all of them confusing to me. I would be a games programmer now if I'd been able to get my head round it
WHY DO I ALWAYS FORGET GUACAMOLE NEEDS LIME?!?! Now I have to go to the shops.

SO COLD
It's March the Turd! The day when people try to do a poo while walking. I love old English traditions.
@standupmaths missing a trick, dude: leave your front door clopen. Burglars will be unable to break in, because there is no "in".
Be broadband is down! O woe, I will have to go outside and enjoy the beach.
Caught out in the rain! Where's my @mathsinthecity umbrella?
@enoFsamohT like all traditions, it's as real as you make it
Physicists: this (double!) rainbow is slightly bigger than my camera's field of view. Moving won't help, right?
@peterrowlett oi, I am expecting an email from you about talk dates
@peterrowlett hey, it worked, didn't it?
@jjsanderson I couldn't see it. Is it because I'm colourblind?
@Talithin gosh, am I famous?
@Talithin if you download that file again, you'll get the finished thing. It was my 4th year project
@Talithin oof, you're doing proper maths.
@Bishnavitch I can give you a lift after the film I'm seeing tonight

To some, programming can be addictive, like a drug. That's why I use Haskell.
@Htbaa no side-effects. It is a terrible pun.

@Bishnavitch my friend @Samuel_Hansen has just interviewed him! blog.samuelhansen.com/post/188718312…
@aperfect aw man I just lost the scone game. Now I want one too.
I miss the old Pukka Pad paper. You can hardly ever get a clean tear from the new kind.
Just fell over. All this thinking seems to have drained the blood out of my legs. Clearly not match-fit.
@peterrowlett shockingly, I don't have one in my esoterica collection! Appalled at myself.
@Samuel_Hansen you're getting faster, not slower like I was expecting. I thought you'd turn up on a canal boat next.
this video is ENORMOUSLY pleasing. youtube.com/watch?v=FQMO6v…

@elinoroberts that's a very Pocahontas attitude
too clever, google! Search for "zip file mime type". I thought this kind of categorical expert system was abandoned in the 90s?
@brittneybean adverts? Ticketmaster handling fee for the Christmas party?
@brittneybean hey, at least if those catch on they'll be accurate. Look what the mackems are trying to promote: sunderlandsoftwarecity.com/home.html
@brittneybean hahahahaha I've just looked at their twitter and it's full of events happening in Newcastle
@ellenirites a lion tamer. Isn't it obvious?
@Samuel_Hansen @peterrowlett let me try. Is this your interview with Neil deGrasser Tyson? weknowmemes.com/2011/11/watch-…
@christianp @Samuel_Hansen @peterrowlett who is Neil deGrasser Tyson? Maybe a relative of F Scott Snitchgerald
Wow, hmv still exists! And there are people inside! And they're not *all* old women buying presents!

the spambots have outwitted twitter by changing their names to /x(firstname)\d{4}/ instead of /(firstname)X\d{4}/. Modern-day Einsteins!
@RANIELDANSON smart trousers too! Is Ranson going up in the world?
@JSlayerUK did you watch that thing on bbc four, then?
@JSlayerUK bbc.co.uk/programmes/b01…
I reject this applause-sound completely. There is no way that many people wanted to attend a recording of Brain of Britain.
@pkrautz @danaernst it's CC, not open-source.
@danaernst @pkrautz there are mathematica notebook versions of the chapters on the wiki, so maybe they're the source, but I can't load them
@brittneybean is this something to do with conspicuously throwing out your LPs of next year's hot new pop act?
@brittneybean sorry, I'm trying to write an entertaining maths article. My mind is jammed in "try too hard" mode.
@GPRPichot @pkrautz @stecks @mathblogging sorry, try going straight to youtube: youtube.com/watch?feature=… - my blog has occasional DNS problems
@Andrew_Taylor yeah, word order: "up to 16 killed by soldier" is less ambiguous
@RichardWiseman consider it an affirmation of your respect for your heritage. He'll like that.
@GPRPichot thanks. NP just says a solution can be checked quite quickly - being able to check at all is enough for random guessing to work
@monsoon0 does it work well? We have a similar thing called MAGIC but it's pretty much universally disliked
@GPRPichot twitter doesn't really have enough space to get into the subtleties of it.
@EliotBall I'm skeptical. Is it by design?

@nulibsage I met one of the photographers in that book while out looking for the aurora at tynemouth! I don't know his name, though.
"we relabel the $i$th letter $w_k$." Does nobody check PhD theses?
@peterrowlett what news?
@peterrowlett ah, Durham's joined. My mind: not blown.
@gingerbeardman great, now my google adverts are going to be full of that Ruark radio for the next month. So expensive!
@aperiodical well, that didn't work, whoever posted that
forget about Pi Day tomorrow, today is March's first Unambiguous Day: While 12/3 could be 12th Mar or 3rd Dec, 13/3 can only be today!
@standupmaths is "avoid all things which increase risk of death" a good strategy? A greedy algorithm, if you will.
this BLT is way more than the sum of its parts, or even the product of its parts. This BLT is more than the tetration of its parts!
@TimandraHarknes @standupmaths could I outsource the worrying, and blindly accept the advice of a third party?

@brittneybean what happened to e-s-p-r-e-s-s-o.com? It's serving all sorts of nonsense now
@HoeJodgkiss you only said that so somebody could call you a PDF-phile, right?
@outofthenorm2 I'm going to make a comment, but I also have editorial comments; where would you like those? email?
@standupmaths oh my god, is that a temple of NOD?

@charliesgames first thought: quaternions are what you want. I have code at github.com/christianp/war…. Busy at the moment.
@charliesgames but this kind of thing is exactly what hardware T&L is meant to do, I think. Ask an OpenGL person.
@sciencefest is there a way to link to a single event on the website? Trying to tell my mum about the gaze aversion talk tomorrow
@ScienceFest but that doesn't have the description!
@charliesgames can't you use opengl's rotation functions? morrowland.com/apron/tutorial…
@charliesgames then I'm stumped, sorry. I'm no good at optimisations, we don't do those in real maths :)

@standupmaths you should get into sage notebook: sagenb.org I'll see if I can do that plot after talk+cakes afternoon here at NCL
@outofthenorm2 @standupmaths that chart, with a log-10 vertical axis, might show no. of digits correct better
oh! just noticed @peterrowlett linked digits of pi to the first person to calculate them in his post travels.peterrowlett.net/2012/03/happy-…
@yomcat @peterrowlett @Samuel_Hansen honestly, MathJax is dead dead easy. There's a wordpress plugin. wordpress.org/extend/plugins…
@standupmaths I prefer to write pi in base-26^9 and write the first digit as "christian"
@standupmaths gosh, I had an odd moment of tweet-blindness where I thought you said to look for your name. Same method works, anyway
I'm so enormously happy with myself for remembering to put the garlic bread in the oven. For once, pasta night is proper!
@RachaelBailes you should hear the outrageous things my colleague has to say about the humanities

I'm watching videos of animals embarrassing themselves. So far I've watched two dolphins collide mid-air and a hippo with terrible diarrhoea
@peterrowlett nobody is going to misinterpret 3/14 as referring to the 3rd of Mega-February

@standupmaths should I be updating the MathsJams map with your van's coordinates?
@TuringSunflower can you explain the link between Turing and sunflowers please? Is it to do with reaction-diffusion and that sort of thing?
@MathsJam GLA: we meant you need only one of the first two steps, ie 2332 is a solution
@christianp @MathsJam or even 3223 would make more sense to you! Forgot which way round you had it
I like this a big lot: thisiscolossal.com/2012/03/clouds…

@trackinthebox why don't your URLs have the date in them? Isn't that sort of the idiom within which your site operates?

@jcoglan that's what setdefault does. get doesn't set it.

@ColinTheMathmo @walkingrandomly @ben_nuttall is there a well-known place to download infinite sequences such as primes, digits of p, etc?
@ColinTheMathmo @walkingrandomly @ben_nuttall if not, would it be worth setting one up? eg keep sending sequence elements until you stop it
@ben_nuttall @ColinTheMathmo @walkingrandomly maybe something like calculatefor.me/1000/digits-of… would give you 1000 digits of pi in a plain file
40 posts in, I'm beginning to regret deciding to retag all of the posts on the @aperiodical
@outofthenorm2 @aperiodical works for me. What do you get? The links on names are just to their google+ profiles, thought it was polite.
@outofthenorm2 @aperiodical ahh, it's set to limited visibility. Seems the original post is also hidden. Not sure if I should just quote it
@walkingrandomly @ColinTheMathmo @ben_nuttall not necessarily. It's definitely quick to just download a list, if that's all you need
@walkingrandomly @ColinTheMathmo @ben_nuttall and especially if you don't have Mathematica (or Maple or whatever)
@walkingrandomly I can install that on my home PC... but if I'm just writing a quicky python script, feeding a file in is more convenient
@Electrokittie only three spokes, so the only potential outraged party is the residents of the Isle of Man

@AdrenalGBR I've forgotten how that integer partitions grid you showed at MathsJam works. Do you think you could write something about it?
I'm not comfortable with Newcastle doing so well.
In English, "first" and "second" have nothing lexically to do with "one" and "two"...
...We just need one more word to go between "second" and "third" and we can finally start counting from 0 like civilised human beings.
I suggest "first, second, twird, third, ..."
"twird" a homophone of "turd", of course.
@pkrautz isn't that how "third" is pronounced by ze Chermans?
considering writing my new, correct, ordinals into the @aperiodical's style book.
@pkrautz ah, jetzt verstehe ich! As is traditional, English mathematics is a step behind the Germans.
@pkrautz aw, now you've got me looking in the book of numbers to see if anyone does do it my way
Wait a minute. What?
@pkrautz difficult. We have separate author/category feeds, which might be best. Certainly don't aggregate the news.
@pkrautz maybe just aggregate the "features" feed? aperiodical.com/category/main/…
@pkrautz gosh, well, it'd certainly bulk out that news section, wouldn't it? Time to cc @peterrowlett and @stecks and see what they think

@Samuel_Hansen for a less gregarious personage than yourself, that would be. Never mind, I'll get by with however much Hansen is going.
@christianp @Samuel_Hansen I think I meant, "that would *not be quiet*". I've confused myself. Eugh.

an hour ago, I decided to get up to turn the heating on. Still hasn't happened. Can I actually stand the cold, or might my legs fall off?
@pkrautz yeah, but the uncommunicative mathematician isn't a recent invention.
this might just be it - RT @rmehigan: @christianp e-mail vs snail-mail, e-books vs .....tree-books ?
@pkrautz I think this has boiled down to a question that requires a few years' scholarship and library-usage to answer. So not for twitter.
@CardColm @alexbellos shameless!
@IanMulvany the interface is so bad I'm now using tweetdeck. So, very bad.
@Samuel_Hansen @pkrautz oh absolutely. I'm just not worried about pure maths disappearing due to lack of communication.
Shelf discipline has completely collapsed in this cupboard. No idea where anything is any more. Considering joining the Foreign Legion.
@GPRPichot @pkrautz @Samuel_Hansen Cedric Villani is excellent!
@Samuel_Hansen @pkrautz and I'm not worried that that won't happen. Man, I'm bad at articulating opinions.
@Samuel_Hansen @pkrautz so what I mean is: pure mathmos on the whole are uncommunicative, but there are enough evangelisers to balance out
My prime factorisation t-shirt by @jgrahamc has arrived! blog.jgc.org/2012/04/make-y…
@aperiodical @Gelada @pkrautz @Samuel_Hansen a point-counterpoint might be fun. Can I find a serious mathematician to back my side, though?
@Samuel_Hansen well, I'm still just a postgrad and my PhD has sort of stalled, so my opinions don't really have the weight of experience
@peterrowlett nooooo! I still have things to do tonight!
why does it take five seconds to paste plain text into windows live mail? Why is there no better free mail client for windows? AGRSGSGFDSAF
@HoeJodgkiss very nice!
@DanielColquitt I really disagree. I've never liked thunderbird.
making myself stay up so there'll be a good program on the radio to fall asleep to later. Feels like bad logic.
The seagulls are either very upset or very excited about this chap fixing the roof they normally sit on
@HoeJodgkiss this might be good reference material for you if you're still mathsing: pinterest.com/olololol/
@peterrowlett @pkrautz double retweet! Proudest man in Britain?
why would the PDF version of an article cost money while the HTML version is free? HTML is more convenient.
@komiga no, not complaining. Just confused. Maybe I'm missing something.
@peterrowlett it gives you the citation with page numbers in the HTML.
@peterrowlett although, as the HTML is freely-available, I'd cite it with a DOI
@peterrowlett they've put markers for the page numbers on the side of the HTML
oh! Might have solved it! It's possible I loaded the HTML version of the article while at uni, but now I'm back at home. Doiii
I've recorded a pretty OK 10 minutes of maths exposition but video editing on windows is either expensive or doesn't work. Suggestions?
@IanMulvany That looks dire! Are those breadcrumbs?
@aperfect thank god Jayce is at the end of that cavalcade of humdrum. But no Ulysses?!
Made with one cut! (and a lot of folds)
@jurieongames @danielpunkass well, now I know what our US version is going to be called
@Samuel_Hansen less tweeting! more editing! Hyaaa!
@Samuel_Hansen want to know what I did today? 5 games of Company of Heroes and a kirigami butterfly.
@Samuel_Hansen oh, I forgot the enchiladas. I made some OK enchiladas.
@Samuel_Hansen then I must admit defeat.
@haggismaths that would make a good Snapshot on @mathsinthecity

@jcoglan yes! This is what puts me off using Ruby! You have put it into words which I agree with!
@outofthenorm2 great post! Like appearances of Elvis, appearances of the Fibonacci sequence are massively more satisfying when based in fact

@pkrautz umm, apropos what? Getting npm on windows is hard (or was, haven't looked recently) so I haven't done much with node.
@pkrautz thought so. Is this to do with the people who want pre-rendered SVG?

@walkingrandomly @aperiodical we have, and I thought it was in the news queue, but apparently not. I'm no CAS person: why Octave over Sage?
@walkingrandomly as I don't know enough to make an informed decision, would you like your post reposted verbatim on the aperiodical?
@jcoglan *certain* Android browsers don't support it. My Transformer does, but my Desire HD doesn't.

@NoelAnn @IMAmaths it can't, really. There is a project called JSXGraph which does (and uses MathJax for notation): jsxgraph.uni-bayreuth.de/wp/
@NoelAnn @IMAmaths but broadly speaking there isn't a perfect solution for drawing graphs like there is for displaying mathematical notation

@EliotBall nice pictures! Were they made in Mathematica?
@EliotBall I don't have Mathematica. Coming to realise with my recent blogging efforts that I should pick a CAS to learn.
@CardColm very clever!

@standupmaths yet again, the North East eschews nerdy comedy. We've got a ruddy Science City!
@franklinheath @jamesgrime mine was as big as it could be. I just had a very wide tube. Going to try with avreal pringles tube today
eesh, pagelines needs upgrading AGAIN. Blame me if the @aperiodical disappears for a bit.

@pkrautz is the new @MathJax https CDN address official yet? It still says cloudfront in the docs mathjax.org/docs/2.0/start…
Tomorrow at Newcastle @MathsJam I will be making some maths propaganda posters to decorate my department's uninspiring walls.
@nulibsage when? Where? I might be able to not miss it this time
@nulibsage well then! Perhaps you can work in a plug for tonight's @MathsJam as a social media science thing
Reminder: Newcastle @MathsJam is tonight, 7pm, at the Charles Grey. I have a paper enigma machine, some fibonacci facts and a lot of puzzles
Danger: mathematicians at work

@HoeJodgkiss that exists? How do I watch it?
going to go down to the beach tomorrow and write the next @aperiodical round up. It's going to be good.
@jamesgrime @numberphile oh no, either you've scooped us or inadvertent synergies are happening. @aperiodical has a similar post brewing.
@jamesgrime @numberphile @aperiodical and we were all scooped by Conway and Guy 14 years ago.
@stecks it was Maurice Chiodo. He's a group theorist now.
@jamesgrime @numberphile & I'm a tiny bit disappointed you didn't fit in a "crore, what a palaver!" joke. Maybe that can be my contribution

@standupmaths I'm going to the Henry Moore thing at the science museum tomorrow. Are you by any chance around?
Weeping a little tear for unloved maths: the guides at the science museum had never heard of the Henry Moore exhibition in the maths hall
Oh. Maybe this is why: this is the whole exhibit
How recent? #disappointment
@peterrowlett still not clear enough. I reckon "@aperiodical triumvirand" would be better. #lahahahatin
@peterrowlett ...but wikipedia tells me it's just "triumvir". Well, I know what my bio will say, never mind yours.

sorry, that's the word with no repeated letters, containing the most contiguous subwords
@CardColm of words which use letters at most once, I have found the one which contains the most contiguous subwords, but it's very rudge
@CardColm I mean rude

@jcoglan something like this, slightly too long for a tweet: gist.github.com/2891557
@jcoglan probably not, since nobody says things like "at MOST n uppercase letters".
@jcoglan basically: I'm a mathematician, so I immediately looked for the strings Vault can't generate, never mind if they're not needed.

@jcoglan I've updated the gist with some sample output gist.github.com/2911970

@Bishnavitch not sure. I asked the lady what was in it and she just told me the price. Very confused.
working through these testing reports is going to kill me
@eAssess but that isn't really a blog, because that post doesn't have a unique link. Where will it go when the next article appears?
@stevenstrogatz I wrote up your UK map redrawing paper for @aperiodical but couldn't find what "modularity" means. Is it somewhere in there?
@CardColm yes I did! Thanks.
Am appalled at how good our first year mathematicians' handwriting is. Though volunteers for a UX test might not be a representative sample
@aperfect but then you've made two mistakes
@stevenstrogatz thanks, but [16] refers to [15] and [15] is closed access. Can you give a handwavey description of what it measures?
@stevenstrogatz never mind, got access through VPN to my uni. Would "it's a measure of how much better than random the division is" be fair?
@stevenstrogatz ah, super! It didn't even occur to me to try wikipedia
this album is completely superb: Floreat by Mara Carlyle emusic.com/listen/#/album…:

@CardColm @peterrowlett I couldn't possibly say
@Bishnavitch ehhh, which one's that? Yes provisionally.
@Bishnavitch at 10! No way!
Sprained my knee playing table tennis. I hope it doesn't swell up or do anything more painful than it currently is

@sotnasaras secondary challenge: do it in a foreign country. Tried it once on a girl in a Flunch in Brussels. She just handed my coins back.
@jcoglan he's right though, using his name in phrases is fun: "Cameron Up The Khyber", "Cameron Obscura", etc. ad infinitum
@jcoglan I haven't yet! There's some interesting discussion of methods in the comments on my blog, if you want to pass some time.
@jcoglan ok, I might have some time to look in a few hours
@jcoglan I've been meaning to say - did you just copy my code to compute stats? Because mine was very wrong.
@jcoglan good! Because my original code calculated num. samples/num. characters. Was on the verge of handing my degree back when I noticed.
@mathsinthecity only one math? Is the supply running low?
@plusmathsorg I would DM you if you were following me

Day 2 of my knee's separation from its socket. Have brought in Archbishop Desmond Tutu for reconciliation talks.
If that fails, I have a roll of tubigrip. It's a tense moment. (I WISH! do you see what I did there?!?!)

@mathpunk you need square brackets around the "keywords" array
@ColinTheMathmo wow, defined in terms of circumference not radius! Did that rule start as "must complete a full roll before being touched"?
@nulibsage oh, it's you who's taking over our office! You'll be glad to hear it now gets wifi signal, which wasn't the case last month
@mathpunk but if you're doing this by hand, can I suggest YAML instead of JSON: yaml.org/start.html
@ColinTheMathmo "a full roll" is probably an easier rule to explain, though, don't you think?
@ColinTheMathmo how interesting!

@Bishnavitch well, it lives on her safari park. She showed us those photos last time she was over here.
@Bishnavitch yes, that's her, but she's in Tanzania now.
to clarify: I'm not sure if my aunty took the photos, but they're from her safari park. She's also just a family friend, not a real aunty.
@Rosalot somewhere near Arusha in Tanzania. I've forgotten the name of the company she works for

@haggismaths relatedly: are you aware of blackboardoftheday.com? Etienne Ghys told me about it when he visited last week
@LeedsMathsJam I'll have one at Newcastle, and I think @stecks will have one at Manchester. Prepare some secret messages!
@jcoglan echh, no. And got a very busy week.
@jcoglan where was your data?

I've written a jQuery plugin that gives you an instant @MathJax preview of any LaTeX you write in input boxes: christianp.github.com/writemaths/
@mathieuruellan What do you mean?
@pkrautz I've just fixed a bug with IE. See if that was your problem too.

@jamesgrime @standupmaths @penguat @KSCMaths @MathsJam Grime Bice? That gives you a colour scheme, too.
@elinoroberts @jjsanderson whatever you're doing: have you worked in a reference to the tidal effects on the LHC? That filled me with awe.
I've made a wordpress plugin which applies my instant LaTeX preview thing to the comment box under posts. checkmyworking.com/2012/06/instan…
I'm thinking of doing a piece for the @aperiodical on people's relationships with LaTeX. Do you have a horror story or moment of brilliance?
I'm particularly interested in mathematicians who don't use LaTeX: what's your excuse, you heretics?
@St_Sebas do you write maths often? If so, what do you use?
@CardColm can you say a bit more about how it changed your life?
@pkrautz should do. Can you point me to a site with disqus comments?
@pkrautz no, just with disqus. Never mind, found one of mine!
@danaernst @pkrautz @disqus should work straight away. Disqus just provides a textarea.
@danaernst @pkrautz no, my plugin loads mathjax if it isn't already there. But you should be using Sam's plugin anyway.
@pkrautz @danaernst oh, disqus' textarea is inside an iframe, so I need to add a line to my plugin.
@Bishnavitch @Electrokittie @HeyCwiss is it any good?
@danaernst @pkrautz github.com/christianp/wp-…. Wait a mo while I make it work with disqus though. (unexpectedly complicated!)
@danaernst unzip in your wp-content/plugins directory. Activate in the admin plugins page.
@Bishnavitch @Electrokittie @HeyCwiss your excellent argument has convinced me. Yours at 7.30?

lunch and then I battle the Stupid Bug Mountain.
@jcoglan commas, spaces, whatever.
@jcoglan my results.txt is now in the same format, at gist.github.com/2911970. We differ, and I'm pretty sure the error is with you
@jcoglan in base 10, we agree until the subsequence (...,9,8,9,5,3,1,0), and you have an extra digit in your output

@icecolbeveridge what was the other one?
@icecolbeveridge but there've been plenty of big real maths stories: Agol's Virtual Haken proof, Goldbach progress, potential ABC proof...
how odd: @standupmaths's radio 4 documentary on Turing is still on iplayer, but can't be found using the search.
@icecolbeveridge there really wouldn't be much point in the mainstream press reporting those stories.
@icecolbeveridge I disagree completely.
two games of Risk and *then* writing our big Turing post was never a good plan. Moody's has just downgraded it to a Very Bad Plan Indeed

Looking at the @aperiodical's stats, it seems Shouryya Ray is twice as popular as Alan Turing. Disheartening.
@standupmaths EXCELLENT. Have you seen the description of railway junction logic gates? I saw it when I was 17 but can't remember the author
@standupmaths if you can make use of someone in the Far North East, I'm in.
@standupmaths not emailing because a) I'm too cool for school and b) I have a woman on the inside of your operation, Parker.
@ben_nuttall you must be really mad that Prince William uses that title despite not having been awarded it by the Roman Emperor
@standupmaths my PhD is in computability and exactly this kind of thing, so I can help with design
@goddent83 I think it was two Cambridge postgrads, circa 2003/4, reported in a paper but not sure which. Junction boxes work as logic gates
@goddent83 I have googled long and hard and turned up nothing but people making external, electronic, logic gates for model railways.
@outofthenorm2 @goddent83 @standupmaths that is precisely it! Thank you!
@HilariousCow already done: Prince of Persia refusing to walk off ledges.
@HilariousCow unlike walking into walls, where the character has no mind of his own, in PoP he's visibly struggling against your command
@HilariousCow for a while I've wanted a platformer where "your" actions don't need to be coherently displayed (transition animations etc)...
@HilariousCow ... but the character follows a tiny bit behind, properly animated because the game knows in advance what it's going to do
@HilariousCow yeah. You've got to fiddle things so the character never gets affected by something you don't, breaking the illusion.
@HilariousCow a single-agent Portal-ish environment would do, with you playing the character's "mind's eye"
@HilariousCow yes! Got to make that now!
None of the doors in the student union make sense. There's every combination of handle/button/automatic/signage.

Dear Microsoft Word, Thank you so much for noticing how wide my screen is, but I don't actually want you to zoom in so the page fills it.
while I'm pretending to write letters: Dear VMWare, Why does your one-click unsubscribe link go to a page I need to click on two more times?
I don't tweet boring work things much, but the PENS import by @SCORMCloud is amazing!
@JanvierUK that's pretty close to your height as well, isn't it? #everyoneistinytome
I wish right guard would stop changing the names of their deodorants. What's the big idea?
I've said "what rot" so many times in the last 10 minutes browsing this conference's programme that the words have lost all meaning
@stecks I demand less boring tweets! Or fewer boring tweets!
@stecks @diffractionman I am. Why?
@stecks yes, I'll do a talk on something, probably princess/castle. Definitely do aperiodical something. Hosting slides is a good idea.
@stecks though really, mathsjam.com should be doing that.
@stecks I worry with the big mathsjam that Colin wants it to be a private party and reporting from it might ruin it a bit.
@Electrokittie you just apply directly to the institution
@HilariousCow manicheanima.
@HilariousCow a portmanteau of manicheanism and machinima?
@HilariousCow it describes basically Peter Molyneux's entire oeuvre
The screen reader JAWS costs $895. Because blind people get the same grants as people who need, like, new doorways built for them.
which makes it hard for me to test, since I don't know any blind people, and don't have $895 lying around to enrich a profiteer with.
@jcoglan so do I fill my HD with noise to make a point, or with "all work and no play makes Jack a dull boy" so it doesn't look random?
AAAAA I only work part-time that is too many issues AAAAAA
I have an almost uncontrollable urge to write a story about the Mormon grammarian P. Dan Tick
apparently Newcastle University has 4321 postgrads. That's a nice number!
@brittneybean I wouldn't be surprised if you said you were visiting a walmart that had an army base.
@madcaptenor you're mistaken. These enlightened individuals are correcting their wicked foreign ways.
@nulibsage I look at my diary for next week. It is a vast empty nothingness. Except for that exact hour. Typical.
@mendeley_com what's the point of attaching files to my library if it always says "we don't have permission to make this file downloadable"?
@jcoglan just add more classes and rules, then freely-reduce the resulting inheritance tree. #unhelpfulneckbeardadvice
@jcoglan sorry, I meant directed acyclic graph, not tree. Because that would be too simple.
there is a layer of bacon-smelling air about three feet off the floor of my flat. Dare I follow it to its source?
@Nathan1123 a bad programmer would just hack over it until it looks like it works. You're on the right track
deleted the blitzbasic forums from my bookmarks. There's hardly ever anything interesting there any more
It's finally here! After literally a quarter of a year, here's a load more interesting maths esoterica aperiodical.com/2012/07/intere…
@ColinTheMathmo I asked Katie but she's AWOL, so: do you have a picture of last year's MathsJam we can use for an @aperiodical post?
Can't think of a single good reason why Smash wasn't instead called Packet Jotato.
@HoeJodgkiss the aristocrats!
@stecks it isn't great - Colin's all blurred. I'll ask on the @MathsJam twitter
has anyone got a photo of last year's @MathsJam conference that they wouldn't mind being used in a post on the @aperiodical?
@stecks oui
@peterrowlett yep, it can go whenever.
the Irish one from My Life In Film is in everything now. Must have got a better agent.
was Dead Boss given that weird inappropriate piano theme tune just because it was written by women?
or, if the writers specifically asked for that theme: what were you thinking?
It's a lovely sunny day in Tynemouth! Is anyone else out here enjoying the festival?
@peterrowlett it went OK, then? No bugs?
@peterrowlett hah! Excellent.
@acmescience much better!
@ben_nuttall @stecks @aPaulTaylor that's more of a combinatorics and designs problem, surely

@alexbellos why's it only got one number? You could do that to a normal die. The joke with a mobius one is you can't decide which face is up
@Calibrand do you actually, though? The sentiment is cheapened by your tweet history. I'm now going to make an effort to avoid you.
11:11!
mathematicians: does anyone else find the misuse of "hence" in a proof really annoying?
@aPaulTaylor I think you mean "no, hence now I am paranoid that..."
@peterrowlett I think we need to submit it to be reviewed by a person. There's a link somewhere in the webmaster tools

.@WWMGT @stevenstrogatz @Wrangler314 see my previous tweet for all words I could find with vowels in reverse order. Excluded "unnoticeably".
also "fulgoroidea" and "uncoincidental" if you allow repeats of vowels.
can't find any words with all vowels + Y in forwards or reverse order. Another reason Y is not a vowel
Omg, just realised Tynemouth Sainsbury's is in walking distance. #sixandtwotwelves
@CardColm gosh! My word list must be missing a lot of words
@CardColm oh hang on, that's in forwards order. Panic over!
@CardColm ah! I see now. Currently walking to the shops so can't check my sums
Ok, further corrections will be ignored unless told facetiously. Clearly I made an error

Oh no. For the first time ever, I tweeted what was meant to be a text. It was a long workshop.
@pkrautz I think not: cross-site scripting problems.

Descending into the pits of the @aperiodical post queue to hew some maths news from the living rock. Got my undecidability canary with me.

@jcoglan is it possible to just cover one's ears and hum until ECMAScript 6 is widespread?
chrome, you are using 200mb of memory with one blank tab open. Explain yourself.
the manufacturers of this chilli have rated it "HOT HOT HOT". Maybe if you were raised on an exclusive diet of milk and yoghurt. Weak.
a more accurate label would be: "This sauce was produced in a factory where chillies are handled"
it has the consistency of puppy sick. I think this'll be the end of bad chilli news.
oh no I discovered the programmable turtle in tekkit
At least be consistent, guy's! (excellent farm, though)
@standupmaths good decision: "standupengineering" is pretty much a tautology. And are you implying you're under-employed?
@jcoglan I use the cursor keys all the time. Because sometimes neckbeards are just wrong.

not sure what madness caused me to say MathsJam starts at 7.30. It starts at 7. Maybe I'll be alone for half an hour.
@MathsJam NCL->MAN we're having trouble decoding your message
@outofthenorm2 @MathsJam yes, and it's not a bad game. A good mental workout
@FOTSN for the safety of my fellow road-users, I did not account for crusts. Or the fact no pizza technician distributes toppings uniformly.
@FOTSN stuffed crusts introduce another problem - they only accrete linearly with pizza size.

@jcoglan do any of the JS module frameworks have relative import paths and namespacing? Or an equivalent of python's `import module as x`?
@jcoglan yes, just looking at the docs now. So the global state you're complaining about is just in naming dependencies?
pretty stoked about how much of my CPU this set of slides is using. Stopping my other programs running means it gets my full attention!
@jcoglan is there any need for global module names? Why not make every `define` anonymous?
@jcoglan I assumed that if you require 'sub/mod', then anything required by `sub/mod.js` would be found relative to `sub/`. Apparently not!
@jcoglan here you go: gist.github.com/3176512 I'm sure it must be possible. It's mad otherwise.
@jcoglan ah, I didn't try ./ ! Makes sense.
@daveinstpaul @MathsJam what do you mean by "level"?
@daveinstpaul @MathsJam oh never mind, got it now. Good. I thought there'd be a simple solution like that.
@acmescience I see your site. Dude's probably got malware
oh lovely, I just noticed someone's written a nice blog post about my rambling fibonacci grids video: andysunknownquantity.blogspot.co.uk/2012/06/thinki…
well, that was uncomfortable. Followed a women home down a darkened street. Turns out she's my next door neighbour.
@GeoffBath @ColinTheMathmo hence the mathketeers' rallying cry, "one for all and all for 0!"
@daveinstpaul very nice!

one day I expect to hear Pearson have bought the times tables. We got a spam at the @aperiodical from a subsidiary offering "maths links"
the first email didn't identify them as from TutorVista (owned by Pearson), but the reply to my email saying "no thanks, I'm not stupid" did
The @aperiodical is listed on google! Finally! cc @peterrowlett @stecks
@madcaptenor it's **. There might be a good reason for that, but there probably isn't.

@mathsinthecity because I have a camera obscurer
I've helped Cushing make a pretty excellent card trick using a de Bruijn sequence and a full 52-card deck. Going to do a video tomorrow.
@jcoglan sounds like a pretty compelling argument for a fork of bash
@aperfect where "no Internet" means "copious abuse of a 3g dongle"
I've just remembered I've got chocolate puddings in the fridge. Bonanza!
@CardColm did you see we've reconstructed Diaconis's 6-card de Bruijn red/black trick with all 52 cards? Do you know any better versions?
oh, excellent thefw.com/olympic-diving…
@CardColm we're going to record a video today. Cards as 6-digit binary strings - first 4 face, last 2 suit. Take 64-bit de bruijn sequence..
@CardColm ..take first 52 strings in that sequence, and swap invalid ones (face>12) with valid ones at the end.
@CardColm .. so you only need to remember the rule to generate the de bruijn sequence and 6 6-digit string pairs to swap
@CardColm so is that Diaconis's trick? David reckons Diaconis said there was no easy trick with exactly 52 cards
@stecks best thing about Scotland: they still sell those boxes of cadbury's chocolate milk in corner shops.
@stecks worst thing about Scotland: dirty sheep-stealing Scots.
@stecks no, because they know real money when they see it
@CardColm Cushing is running across to the uni library to get it now
999999999999999934463: the largest integer Chrome doesn't use scientific notation to display
why 999999999999999934463? It's 10^21 - 2^16 - 1.
@ColinTheMathmo press F12 to get the javascript console up. Enter the number. It gets repeated back to you. That number plus 1 gives '1e21'
@ColinTheMathmo actually, to be precise it gets rounded to something a bit lower, but scientific notation isn't used; that's the point
@ColinTheMathmo yes. Of course, chrome can display any number you write in html....
How many people from different departments can sit down in this room before two exchange words, or even eye contact? Current lower bound: 4
@ColinTheMathmo it's for my javascript algebra/eassessment system.
@jcoglan isn't that just a subset of all programmers, though? I've seen plenty of people in many languages that just don't get abstraction
@jcoglan maybe it's more apparent in javascript because it's missing so much due to the lack of a stdlib.

outlook.com passwords can only be 16 chars long, so I had to truncate my hotmail one when signing in. It worked. Paging @jcoglan!
@My_Metro does the "no problems" tweet go out automatically each morning? That's a pretty bad idea.
@My_Metro you tweeted that trains were delayed, then that there were no problems, then another apology for the delays. Why?
@My_Metro ah no, the one I replied to was 8 hours ago
@My_Metro OK. *That* is a bad idea. I have deja vu. Have I complained about this before?
@jcoglan yes
@jcoglan well... "good". Quotes decidedly necessary.
@jcoglan given how often my account has been hacked, I guess the latter

@ben_nuttall like, ("fizz" if x%7 else "buzz" for x in count()) ?
@ben_nuttall I'm not happy with [(x if x%5 else 'buzz') if x%3 else 'fizz' if x%5 else 'fizzbuzz' for x in count()]
@ColinTheMathmo @icecolbeveridge either they were automatically truncating it and then hashing before, or they never hashed
13:37 - time for clothes! Today wasn't meant to be one of those days.
@qikipedia oi, what about 'troublemaking'?
@HilariousCow <16mb memory, 120 enemies... you haven't just made space invaders again, have you?
@ben_nuttall I spent a while dithering on whether constructing 'fizzbuzz' by concatenation was shorter
oh, the reason "google maps" is always trending on google+ is because it counts people posting links to places. #embedallthemediaitllbefine

@peterrowlett @aperiodical another from Cushing: "fermat's last theorem is precisely the physicist's viewpoint of a hot dog"
@jgrahamc I think it's more a product of a desire to have more flexibility in their stock control, which isn't a bad thing
@peterrowlett yes, I think so.
@peterrowlett Cushing says yours are too long
@peterrowlett I worry that directly asking people to search for the site might incur google's wrath though.

Pythonistas: is it possible to write a file-like object to a ZipFile object without doing zip.writestr(fileobj.read())?
@panlepan alas, it's a rolly-round one. We've considered cutting off the blackboard material and covering the walls with it.
@acmescience you explicitly asked for more cranks
oh super, the @aperiodical has been slashdotted! Thankfully, nobody reads /. any more so the server is coping fine
number of people who read the proof before speculating wildly: 0. Never change, slashdot! (for balance, reddit is doing equally poorly)

has anyone considered town planning as a data structures problem?
@kenfodder I was thinking that quadtrees would allow everyone to pack into a small space, leaving lots of green countryside
@mathsinthecity we've been weighing up whether to report that on @aperiodical because it sounds so fishy. Russia Today isn't a great source
@elinoroberts just looked out the window. Correct.
@MathJax oh, I thought it already was. Here you go: github.com/christianp/mak…
@jamesgrime this calls for a public awareness campaign! Can we make a ribbon with a big symmetry group?
@brucel @ben_nuttall wow. Why would they release that with their name attached? It's as bad an advert as a grocer putting out mouldy fruit
@IMAmaths those would look a lot nicer with @MathJax maths.
@Bishnavitch @Electrokittie yes!

Usain Bolt fact: Bolt often gets dirt in his eyes, so at home he's hired a personal eyebath attendant from Grenada Mote-Away Services.
Olympic stats time: who is failing to win the most? somethingorotherwhatever.com/olympic-choker…
hypothesis: something really, really bad happens to North Koreans if they get bronze or silver.
oh man, Team GB has moved up the not-winning table after today's sailors, boxers and hockists choked somethingorotherwhatever.com/olympic-choker…
(Canada still sits comfortably at the top of the table though. I think that level of almost-achievement will be hard to match)

unexpected CP presence at the start of this week's math/maths. You win again, Hansen!
@jcoglan wow! That's like #unhelpfulneckbeardadvice: The Twitter Feed.
@stecks and then your PGP key was in the last place you looked, right?
@stecks toys? I think we're doing mathsjam wrong
just remembered that Sainsbury's was playing Creedence yesterday. I wholeheartedly approve.
I'm watching The Red Shoes. As a keen fan of balletic megacamp, I wish to express my desire that it gets better. Not hopeful so far.

@icecolbeveridge if you put the source to that on github I'll add some nice MathJax to it
@DanielColquitt whence came this thought?
@benkenyon I can do one better: they were playing Alt-J in a mcdonald's I was in last week
@peterrowlett I make it 27. What am I missing? Note Northampton and Birmingham appear twice in the mathsjam.com menus
@icecolbeveridge @peterrowlett ........ oh, boo to that! Sit on the naughty chair!
gosh knitting's complicated
@peterrowlett @MathsJam apparently so! Which is why I started the map
@peterrowlett what does that second sentence mean? I can't parse it. Have another go
@peterrowlett I've discussed that @stecks. I think she convinced me she had a good reason not to do that.
@E_I_W are you going to mathsjam tomorrow? I'm off work with exhaustion so probably won't go. Not sure if anyone else is around,
@stecks @peterrowlett by forgetting to type the word "with", I invented new language! Hooray, I'm Shakespeare!
a pox on your house, dictate2us! Not sure why your emails are being let through by the uni's spam filters
@jjaron @aperiodical the dude who posted it claimed he did it by hand: reddit.com/r/Minecraft/co…
@jjaron are you setting up a "but it's only made of points" pun there?
@mathsinthecity far more interestingly: there's a town called Collegeville!
@mathsinthecity then you might do badly up here - we have lots of villages called things like "No Place" and "Pity Me"
@mathsinthecity it's grim up here, you know.
@HELIUM_HEED it's uni resits fortnight
Woke up covered in cuts. I'm worried my house might be infested with Tories.
@CardColm I have a couple in my office, but 1) I'm not there today, and 2) they're not very neat
@CardColm unless by "completed" you meant "all of the hyperbolic plane", in which case I don't have one
@Electrokittie oh man now I want doughnuts too
Email isn't an interactive medium with @peterrowlett. It's more like leaving messages in a time capsule for the benefit of later generations

@outofthenorm2 probability it stops after N goes, or what?
@acmescience what, another one?
joyous! cuteoverload.com/2012/08/22/sea…
@acmescience us?
@outofthenorm2 there's always a chance it will stop, so expected number of rounds until it stops might be better
@peterrowlett yes, it's a result of how much email you receive rather than how much you read
@bucharesttutor @icecolbeveridge I've always had a couple of problems with that, starting with the letter x. There is a best way; use it!
@bucharesttutor @icecolbeveridge no, I mean the x on that page isn't the best.
@bucharesttutor @icecolbeveridge in fact, the X there is how I would write a Greek letter Xi
@bucharesttutor that's the same letter. Don't tell me we have different ways of spelling letters!
@bucharesttutor oh man, it's me who's wrong. Whoops!
@icecolbeveridge @bucharesttutor I think this calls for another #twittorthography survey
@MitchKeller @peterrowlett @aperiodical that's what I was thinking of. So what's common in the US? Surely not no. 1?
@MitchKeller interesting! Does 3 look bad to you, or does the thinking behind it make sense?
@plusmathsorg which one of you tweeted that? I've never known how you do twitter. Anyway: did they try to get you to do 3 at school?
@MitchKeller the thinking is that it looks completely unlike any other x, and especially not like the multiplication symbol.
@pkrautz I have several of these saved in posts on aperiodical.com for if I ever get round to writing them up.
@pkrautz though I'll try storify; it's just that every time I've looked at it it's scared me off
@MrHonner @icecolbeveridge @aperiodical @plusmathsorg they should be. Blame my cack-handedness
"@MitchKeller: Once you start using x there is no longer a need for a symbol for multiplication" Vector multiplication:
@MrHonner @icecolbeveridge @aperiodical hang on! I've looked again and they are touching. It just looks like they aren't because of chalk
@MitchKeller handwritten ones, yes. What do you do?
@MitchKeller but arrows take so long! And a hat is for a unit vector.
@icecolbeveridge @MrHonner @aperiodical precisely! Handwriting is different because it's hard to consistently replicate symbols

@profkeithdevlin I've encountered a similarly annoying Scottish academic who uses "does anyone remember the quadratic formula?" the same way

@aperfect ahem I THINK YOU MEAN CUTTING-EDGE
@pkrautz I did not. I'll look now.
@FontSquirrel how does the kit generator's backend work? I'm converting 60+ fonts so I'd like to spare your server and my patience...
@FontSquirrel ... by doing the conversion locally, if possible.
@md267 @bluecombats @NoelAnn @peterrowlett well, wikia is popular, and could probably be convinced to do mathjax. See nakhmani.wordpress.com/2011/06/17/wik…
@Samuel_Hansen what bands are you already listening to?
@FontSquirrel thought as much. Oh well! I'll sit here pushing fonts through for a while. Thanks for replying.
Sorry dudes, but I just made the best tweet ever from the @aperiodical account. Unless you're RTing it, there's no point using twitter now.

#eas2012 are any mathematical types also wandering around Dundee this afternoon?
Whoops, apparently the hashtag is #eas12. So again: are any mathematical types also wandering round Dundee this afternoon?
@stecks I think I've seen very similar words before
@peterrowlett @stecks I've arrived in Dundee. 7 would be best for me.
Dundee has some very nice buildings!
@icecolbeveridge yes!
@stecks @peterrowlett I have dinner booked for 8! Later?
Dundee also has lots of unapologetically mediocre shopping centres
Euclid street!
The vajazzling shop I noticed last year has closed. It seems not even gaudy nethers are safe from the double-dip recession
*and* a wealth of pleasing sculpture? Dundovingians, you're doing OK!
Oh wow, aforementioned bits-blinging shop was on Nethergate! How did it fail?
Dundevarians? Dundorks? Dundeebriates? What are you called?
@Rathematician is this where that "furry boots are comfy?" joke comes from?
@stecks @peterrowlett 9? Hard to say
Gotta be Dapper Dan!
Henry's coffee house just made me an extremely nice hot chocolate
@aperfect as I often say, lonely fun is the only fun
@maanow @plusmathsorg a case of nominative determinism?
@stecks you should be in Dundee!
@geogebra did you tell us about this? Sorry if I forgot to write it up
@geogebra the ipad kickstarter. Looks like twitter didn't realise that's what I was replying to
man, that shower was like being dribbled on by a dehydrated pensioner. 4/10, at least the temperature was consistent.
and the towel smelled like abandoned popcorn
@HilariousCow 0/0 is not infinity. Or, if it is, it's plus or minus infinity
@EIMathematical @peterrowlett @stecks hint taken, it'll be on the Aperiodical shortly I'm sure
September
@monsoon0 there's probably quite a bit of selection bias
@mathalicious are the weekly videos on youtube the product of the math52 kickstarter? Trying to write you something nice on @aperiodical
@monsoon0 I mean, there was probably a lot of rubbish published in the 1800s that you haven't looked at
@monsoon0 ok, if we're being honest, I also prefer old maths to new. One of my most treasured possessions is an 1811 arithmetic textbook
@monsoon0 "the late William Tinwell" (not an anachronism: it's the sixth edition). "A treatise on practical arithmetic and book-keeping"
@monsoon0 it has a completely different set of concerns to new books, e.g. it tells you how to convert Edinburgh bushels to Newcastle ones
@monsoon0 it's fascinating as a record of how life used to be, and how important arithmetic used to be
Bad tropes in the @EIMathematical weekly challenge video: opens with a cloud of mathsy symbols; people are "obsessed" with the subject.
I nominate @peterrowlett for best sentence on the site this month, for the opener to this post aperiodical.com/2012/09/maths-…

actually, left knee, I'm fairly sure I *didn't* just dislocate you, so buck your ideas up
Kickstarter if I could be bothered: Rubik's cube with internal circuitry.that goes PING when you solve it
More difficult: Rubik's cube that announces number of moves to solution at each step (now that we know God's number it's easy, right?)
on the pinging Rubik's cube idea: would a Hilbert curve through the blocks work, so the circuit is only complete in the initial position?
@jamesgrime excellent cartoon. Remind me to high-five you at the big MathsJam
@jamesgrime yes I was. Young Indie is live-action, isn't it? Not very good, either.
@jamesgrime hmm, hard to decide. How about: you can attempt to high-five me, but I'm at least a foot taller than you, so difficulty: hard
@jamesgrime (I say "at least" in the "I have a rough memory of how tall you are, which time has exaggerated" sense)
@jamesgrime only a few inches off! I never got into Batman: the animated series. I bow before your mid-90s TV expertise
I've really enjoyed sitting in for this Amazon delivery. It's given me time to reevaluate my priorities in life.

today: was going to continue rewriting @NclNumbas with knockout. Instead: getting it to do pretty things with d3.js
so I've missed the day again, waiting in for this package. "Any time between 8am and 9pm" isn't very precise
This is ridiculous! It's now 48 hours since I last stepped outside the house. And the courier might not come until 9pm!
Fresh air! The parcel has finally arrived so I can leave the house yippeeeee!
@DanielColquitt yeah, but they didn't leave a card yesterday so they sent a courier today
Carrot and houmous club! Who's with me today?

@plusmathsorg I like how Gömböc was de-umlauted for the URL: goumlmboumlc. I'll call it that from now on
@GreyAlien you only have one in space, but you might have several in time
@stecks you could while away the time designing an interlocking pieces puzzle and call it Aburrdeen
@mathsinthecity in tropical arithmetic it's 1, so I assume it's the philosophers who take the conventional view.

@AMSGradBlog yes
@AMSGradBlog you've probably got it cached, in fact
@AMSGradBlog yes, working now
@icecolbeveridge it said yesterday that he was leaning out of the car to pick up a parking ticket. Oddly no mention of that now.

@Samuel_Hansen I had the thought before that now might be a good time to do the "are there enough maths communicators" idea from a while ago
@Samuel_Hansen man, you were asking for people to interview you, and you say there aren't enough in your press release, so...
@Samuel_Hansen ok. I'm going to email you a short list of stupid questions and we'll see where that goes
@aperfect @LWigelsworth hello that is a very nice biscuit tin back there yes it is mmhmm
@standupmaths (it's really 27, because midlands towns are in both the North and South lists)
@icecolbeveridge ah, then my map is out of date, and Katie decided which side of the border two towns lie on
@icecolbeveridge @standupmaths some python BeautifulSouping later, I agree with you. I don't have Baltimore or Norwich. Is Baltimore real?
@stecks interested to hear your reasons for putting Norwich in the "N England" list on mathsjam.com
@icecolbeveridge yes, but does it happen? I've never heard anything from them
@stecks @standupmaths half the towns in "N England" are in the midlands. Don't they deserve their own list now? Or could it be "N&Central"?
@stecks yes!

@peterrowlett @MathsJam @stecks ok, I'll find someone in the department with an iphone and commandeer it for a bit
@peterrowlett @stecks got hold of an iphone and sorted it. Should be working now, if you'd like to test it

@peterrowlett can I turn off the "share posts on twitter" option for the mathsjamphotos tumblr? About to upload my pics from last night
@peterrowlett just discovered there's a button to turn tweeting on/off per post, so we can both be happy
@peterrowlett I think it does work on my phone, I just forget to use it.
@peterrowlett and of course I would forget to press the button on the second one

it's just occurred to me that that script solves the numbers game on Countdown, too.
@icecolbeveridge it should use all four cards, yes. What numbers did you have?
whoops, my script doesn't rearrange the numbers. Doh
@icecolbeveridge oh right, you mean with your script. Yes, mine insists on all four.
@icecolbeveridge you can get 24.2857, if you don't mind fractions...

@aPaulTaylor oh man, I didn't think of that! I will recompute
@aPaulTaylor so is oxyphenbutazone's 41 the only unique score?
@aPaulTaylor that's already happened up here. Still marginally cheaper per litre than Sainsbury's own brand, but not by much

@jjaron You're a writer, so coin one!
David has suggested an excellent sequence: a(n) is the first number in the nth OEIS sequence.
I suggested 1+ the nth number in the nth sequence, to ensure we make a novel sequence, but some of them are finite so it doesn't work
previous tweet is total lies. Of course any number is different from no number, so we're still unique

revelation: ctrl+alt+vowel gives puts an acute accent on in windows 7. There must be something similar for grave, but what is it?
@komiga tried that. It doesn't work. ctrl+alt+` produces ¦ for me.
when you enter the second minute of saying "ummm", it's fair to say you've lost your train of thought
@stecks me too!
Ha. @stecks and I are writing pseud waffle in parallel on a google doc. Too earnest!
@stecks 80s laser noises!
@stecks oh god, and now we're pseuding on twitter too.
It's cho'clockolate!
@alexbellos nope, nope and definitely nope. I was *enormously* annoyed to find this out the hard way
@alexbellos and if you're thinking of doing the "gardens" visit instead: it's OK, but not amazing. Go only if you're already in Granada

Sat in the dental hospital waiting to be seen. If it turns out they need to do anything, this afternoon's Maths Aid is going to be fun.
Hah, my phone's picked up the university wifi at the dental hospital. Fantastic.
Let's take a trip straight back to the 90s! I just checked, and rinkworks.com still exists. I used to think it was the funniest.
@standupmaths amazon says a cube in its packaging is 5.6 ounces / 150g amazon.com/Winning-Moves-… amazon.co.uk/Rubiks-9420-Cu…
@peterrowlett um....? Really furious chalk-holding?
@standupmaths would I be spending too many pedant points if I raised the question of whether it's "the Rubik's cube" or just "Rubik's cube"?
@Bishnavitch just had a root canal done, so best not
Person I'm sharing this office with has started laughing very loudly at the internet. I think she wants to chat to break the silence...
... but I find her monumentally tedious. Hoping she'll eventually give up.
I'm getting nostalgic for this morning with the nice dental student doing my root canal
North Shields smells really strongly of weed again. I hope they realise "stonefish" isn't just made by getting normal fish stoned.
@DanielColquitt no replies apart from yours. I think you're right.

@vickytnz I was recently told I have too much tintin merchandise. Impossible!
@DanaKazim Pure: python or Haskell. Applied: MATLAB or maybe Mathematica. Stats: R.
@vickytnz the Tintin Shop in London is the place that makes it all, and well worth a visit. My bro bought me an ace t-shirt for £10 recently
@DanaKazim much nicer syntax, easier to write what you mean without fiddling about with language stuff. If you want speed, haskell is fast.
@DanaKazim python, by far. Try femhub.com/textbook-pytho… and diveintopython.net/toc/index.html

That went rather well. I think the recreational maths seminar is a goer. Thanks to @icecolbeveridge for sparing time and brainpower.

1) claims animals "solve" maths problem. 2) describes problem as "wildly complex", but not in the technical meaning of the phrase.
3) claims mathematicians "discovered" basic fact about graphs. 4) repeats decade-old press release claiming a human has "solved" TSP.
5)finally and worst of all, gives no hint that "hard" for mathematicians has a very different meaning to "hard" for regular people (or bees)
A person called Dana and a person called Daina have favourited my last tweet. I assume one is the imaginary complement of the other.
@icecolbeveridge yes please. Put it in the system!
Newcastle @MathsJam is tomorrow, 7pm at the Charles Grey pub (outside Monument metro station). All welcome, just bring your brain!
did everyone suddenly agree that the past participle of "lead" is no longer "led"? What's going on?
@monsoon0 I saw "lead" in a newspaper (though I think it might have been the Grauniad) recently, and I've seen it in several articles since
@TweetsofCushing where? The top post is still the prisoners
@TweetsofCushing now so do I. Most peculiar. Gavin says you might be ill. Are you?
@hornmaths 'lead'
@C_J_Smith it's WHAT?! I'm not prepared! HOW WILL I DO ANYTHING ELSE TODAY?
I've lost my rather expensive bluetooth headphones. I'm quite displeased.
'...the use
of "percision" as defined in the SQL specification can be confussing.' I agree, SCORM spec. I am very confussed.

Helpful definition of notation from the SCORM 1.2 spec: "If not preceded by a minus sign, the number is presumed to be positive."
No mention of required precision, base system, or which character should be used for the decimal point. Hooray!

@haggismaths thank that person from me. Typewritten maths is a terrible artefact of the mid-20th century.
@peterrowlett is it constructive to rant about someone's mistakes at length? I think twitter is ok because it's ephemeral
@peterrowlett I also meant "permanently"
@BenTormey Get a pair of boxfresh. They last so much longer than Converse.
@elinoroberts top idea! For lunch, or breakfast?
@standupmaths I was planning on using "Chum-in-Chief" but @stecks wrote the article. Which do you prefer?
@elinoroberts ahhh, I need to get the metro at 11, but you've stirred beachy feelings in me. Mind if I join you?
@peterrowlett @icecolbeveridge @standupmaths would you believe I was literally about to tweet that myself before I saw Col got there first?

Twin prime time! 11:13 means PARTY LIKE IT'S A REALLY OBSCURELY INTERESTING SIXTY SECONDS
@AdamCreen really? How so?
@AdamCreen oh, you mean there are 11 more prime minuteses. I use "twin prime" to mean two primes (n,n+2)

@jjsanderson @elinoroberts well, if you live in Tynemouth, this is what happens. You'll have opinions about on-street parking next
@jjsanderson @elinoroberts depends. Which way round the metro do you go? If you go via Gosforth, it's already too late

@jcoglan not a WordPress apologist, but it'll be a plugin causing the crashes. Because of the unique way php works, that's possible!
@jcoglan some combination of turning plugins on and off, and turning on PHP debug logging. Prepare to go back to 90s debugging methods
@jcoglan there might be a plugin that adds a "don't show comments" flag to posts and modifies the get-post-comments function

@jcoglan though if you're writing a book, learn LaTeX.
@jcoglan pdflatex comes with any latex distribution. On ubuntu, try tex-live
@jcoglan all these variants exist because almost everyone, after using TeX for a while, thinks "I can do it better!"
@jcoglan the stuff they have in common is basically all you need, so just stick with TeX-live and don't try to be clever with it
@jcoglan TeX is like the English language: nobody uses it perfectly, there are a million ways to say anything, ...

Having a little rage about the Moodle SCORM module. Not a single line of the code is good.
@vickytnz it's free, which is good, and open-source, so I can see *why* it's buggy. We're on Moodle because BB has broken SCORM support
@vickytnz Moodle 2 is considerably less bad than old Moodle. It's barely tolerable now, but still lots of really annoying and bad things
@vickytnz yeah well, it's for academics :P

@jcoglan the problem is probably with your router (or OSX's drivers, depending on perspective). OSX takes exception to some brands of router
@jcoglan yeah, it's OSX's problem, but its problem is with the router.

Excellent! Google music has a labs feature to give tracks ratings out of 5, which it imports properly from WMP!
Help I've written a strongly-typed DSL in javascript and now I wish I hadn't. I wish I could use Haskell :(
@Htbaa yeah, but it wouldn't be appropriate for what I'm doing
I have no idea why our library has just bought a copy of a GCSE maths textbook from 1987. It's in the "new accessions" list. Weird
Is listening to the same radio 4 programme every night for the whole 7 days it's available because you fall asleep 5 minutes in a thing?
@missradders fantastic! I think it might be time to start the most middle-class petition in history
is it possible to dislike a beard so much it falls off your face? I've been putting off shaving it but it's so terribly itchy now.

.@jjaron it's used when you wish to rule out the case where a is not greater than, equal to, or less than b. Such as when b is a banana.
FOR THE FIRST TIME IN RECORDED HISTORY, Springer LaTeX Search is useful: latexsearch.com/latexFacets.do…. Surprise surprise, it's used in economics
@jjaron =/= excludes the case where they're equal
@panlepan it was a good one!

@jcoglan tonight on the news at 10: man has trouble with new system, claims nobody anywhere could use it better than he
@stecks I was Mjolnirly right.
@Bishnavitch will it really tie the room together?
@mathpuzzle did you notice your site's hit counter recently went over five million?
@jcoglan also, the government plans to reintroduce 10,000 grey wolves to northern towns, to encourage more risk-taking

Oh, it looks like this error is related to the one where objects' constructors are called before they have their prototypes attached.

Dinner tonight: cream of bad idea "à la mexicaine"
Wow. Emscripten! developer.cdn.mozilla.net/media/uploads/…
Tried putting sliced banana on my shredded wheat like the adverts say. It just made the shredded wheat taste like sawdust.
It has just, *just*, occurred to me that $\frac 1 2$, or even $\frac12$. is valid LaTeX instead of $\frac{1}{2}$. Bad idea?
So the consensus is that $\frac 1 2$ is an abomination.
I'm surprised about the unanimity concerning $\frac 1 2$, considering the amount of bad LaTeX I've seen in my time.

Today, IE is crashing so comprehensively on page load that I can't even look at the script console to see an error message. #hateIE #hateIE!
@aperfect I haven't yet forgiven you for teaching me to slouch
@aperfect yes, when we were at Brat
@jcoglan fun fact: I'm currently battling an IE bug where the constructor gets called before the prototype is attached.
@jcoglan even better: the error dialogue is crashing so hard that either a) it throws its own error dialogue, or b) all of IE crashes
@jcoglan I tried the old delete-stuff-until-what's-left-doesn't-crash tactic, but after enough errors IE10 just refuses to load *any* page
When you have not enough dust on your screen to interfere with work, but enough to make smilies look like winkies
WOW. Just wow. The cause of my IE mega-crash was mismatched tag names. That's, like, a 1995-style crash bug.
@CardColm @mathhombre yeah, we're pretty open with our contempt for marking
@HELIUM_HEED yes, you are the only person
Uh oh, Shpongle has come on the music shuffle. Might not feel like accepting consensus reality when I get off the train. #radcommute

@jjsanderson where?
@jjsanderson is that the spot that used to be the awful grill place?
@jjsanderson the art bar has always been called "Barca", and I think they expanded upstairs when the rubbish grill closed
@jjsanderson while we're talking Tynemouth eateries - have you tried the new restaurant next to Marshall's yet?
Proof by induction until you have enough values to put into the OEIS
@jjsanderson no idea. I could've gone yesterday but I panicked and went to Lui's instead. (belly pork was mmmmm!)
@jjsanderson I still haven't been in Allard's. I was put off by the people I saw with half-litre wine glasses sat outside last summer
@jjsanderson none, sorry. I'm sure I can remember seeing a sign once, but I've completely forgotten what it said. Some sort of club?

@matheknitician ooooooh!
@stecks @peterrowlett either of you around for a podcast tonight?
@ColinTheMathmo hah! No it isn't. And the scripts that you put in your page are hosted on a CDN which is very reliable
@ColinTheMathmo the docs at mathjax.readthedocs.org/en/latest/ are up, so you could read through those
@ColinTheMathmo the HTML on that page is very odd - lots of unclosed and mismatched tags
@ColinTheMathmo ahhh, you've got parentheses set as delimiters! Instead of ['\(','\)'], you should have ['\\(','\\)'] to escape the slashes
@ColinTheMathmo don't have the second bit with the parentheses. The page on mathjax.org has two slashes. Should we switch to email?
@ColinTheMathmo yes, that's right. Yes, you'll need quad slashes if it's going through python, or put an r character before the string
@ColinTheMathmo (the python string, that is)
@ColinTheMathmo there's a <p> inside the last <ul> tag. Not closing <p>s is a rubbish thing to get stickly about, really.
@ColinTheMathmo what's the other browser? It should work on everything back to IE6.
@ColinTheMathmo I couldn't commit any time to it, but I'm happy to answer questions
@ColinTheMathmo yes, I didn't look too closely. Apart from all the unclosed <p>s, but whatever.
@stecks @peterrowlett super. We'll cast pods like it's going out of fashion

@jcoglan gaussian integers
@icecolbeveridge it's there, but I've had a busy few days and I don't think @stecks has looked at it
@bluecombats yep! The MathJax bookmarklet might help: dzejkej.github.com/mathjax-bookma…
Living the paperless office dream, but it just looks like I haven't prepared for this meeting and I'm playing on my phone (I am now)
@bluecombats @peterrowlett @aperiodical can't do that in RSS,for obvious reasons
@bluecombats @aperiodical @peterrowlett because rss readers filter out scripts.

@jcoglan @tunixman that's nice, but what problem does it solve? If you can write malformed latex, you can write malformed hatex
@jcoglan never mind, I realised immediately after posting that that it's for programmatically generating latex.

@vickytnz I didn't write it down! I'll work it out again.
@ben_nuttall what are they? I miss my g-u-username from normal twitter
@vickytnz 1/9?
@vickytnz public announcement logic is a thriving field of study! Some fun slides at phiwumbda.org/~jesse/slides/…
Penne pasta, pesto, pepper, pomodoro, and... if these had been portobellos, that would've been amazing. #mushroomsarentteamplayers
oh wow! The list of all primes was 14gb, not 1.4! Extra bonus fun!
@MrHonner all primes (explicitly discovered so far)
@stecks which one? The next one, or the next next one?

You're not spider friend! In fact, what *are* you? Spider friend, you had ONE JOB
@charliesgames oh no! That ain't good! Time for a food hygiene purge
@TwentyThree bummer! I don't use iTunes so I don't know what to do. What happens?
@TwentyThree an iPhone-having friend has just downloaded it successfully. Try again?
@vickytnz yeah, I think that one's lacking some unhinged element the corbis one had. And they're American pancakes!
@vickytnz yes
How did I manage not to notice the metroline hordes until I got off the train?
What they've done is morally wrong, but it's beautiful. Zeroless arithmetic: arxiv.org/abs/1303.0885v1 (via @Gelada)

@evelynjlamb @aperiodical is the fake formula made up for PR purposes not a thing in the US? Our papers are lousy with them.
@ColinTheMathmo ooh! Can we meet tomorrow for coffee?
@ColinTheMathmo but...?
@monsoon0 that's a great name! Like a character from a series of kids' books
A problem with living alone: no sanity check on your appearance before leaving the house.
@My_Metro why do announcements say "no trains in both directions" instead of "no trains in either direction"? Is the first less ambiguous?

@nulibrs oh, I get it! Very clever
@peterrowlett @NoelAnn can I talk to you at some point about Maths Arcade? I think we're going to set up something similar here
@ColinTheMathmo @stecks @helenarney is this a "hung/hanged" type situation? Should we say 'drinked' to refer to when a drink is consumed?
@pkrautz there is not, and I hadn't heard of it before! Thanks!
@pkrautz @MathJax @fgdorais I don't know. I could find out...
@pkrautz @MathJax @fgdorais do you have a blog somewhere that uses jetpack comments?
@pkrautz @fgdorais it won't work because the comments are in an iframe. There are plugins to allow social login on normal wordpress though

I really need to get round to presenting the results to the @aperiodical survey. Some people have given great answers survey.aperiodical.com
@brittneybean that's the second one of those I've seen in two days! What's happening? Is this the 90s revival I've heard so much about?
I'm pretty sure there's money to be made in making man-sized household cleaning appliances. My back hurts!
@standupmaths A chum freezer-burnt his hand with an extinguisher during fire warden training. The irony was more delicious than any icecream
@helenarney @jjsanderson Lor' that was a terrible film! If only they had been bloggers, that might have improved it.
In a jigsaw, you apply rotations and translations to the pieces until they fit. Could you make a puzzle with other affine transformations?
@Thalesdisciple I'm thinking of either a computer puzzle, or you could do something with optics
@Thalesdisciple so: start with 2d image; chop into pieces; apply different combinations of affine transforms to each piece
@hornmaths the exact opposite of my current feeling

@DanaKazim oh, you definitely can fail at salad. My last one was a complete nightmare

This is the best snow we've had all year! It's like icing sugar. Mmmmmm
@DanaKazim it is?
As usual, @TweetsofCushing and I are spending our Monday morning well
@vickytnz well, it's getting warmer. What are you complaining about?
@SherriBurroughs @MathsJam Have a look at my Newcastle MathsJam recaps - checkmyworking.com/category/maths… - we've done loads of different things
@SherriBurroughs particular favourites: the princess in a castle puzzle and the card game Mad Abel
@vickytnz I haven't read it, but it's very very highly recommended by mathematicians. It's like the classic text
I've woken up with a strong desire to see a linotype machine running. The printing museum in Lyon was great
@nulibrs it's the last week of term?! We should have a huge laser display board counting down the academic weeks somewhere on campus.
@nulibrs I don't know why it bothers me, I don't get to stop working when the students go home, anyway
@nulibrs what a coincidence! I've just recorded a thing for my maths podcast about my favourite book, an arithmetic textbook from 1811...
@nulibrs ... it's a lot more interesting than it sounds!
Is there such a thing as an Oxford semi-colon?
I think I might be a chatbot
This might be the best I'll ever do at triple town.

@kirkpatricke is it ok if I give her your email address so she can ask herself? Twitter is too terse
@kirkpatricke I do.
@evelynjlamb thanks for the link to All Squared!
@MarcusduSautoy umm... universal computation is definitely maths, and in my opinion a much bigger innovation
@MarcusduSautoy aha! Anyway, my vote, even though I'm a computational group theorist, would go to calculus.
@icecolbeveridge @standupmaths bravo
Very nice! RT @panlepan: Fr!endly numbers.

@numberphile yeesh, I'm so tired of all these people saying they did a bit of French at school and loudly declaring how bad they are at it
@numberphile we need more high-profile French speakers who can communicate the beauty of French for its own sake. Maybe in a YouTube channel
@numberphile sorry, I was being ironic. Replace French with maths
@hellobuglers wow, I decided I'd had just about enough of that, and then I noticed I was only twelve minutes into over an hour of punning!
@nulibsage is it ironic that that's published in a closed access journal?
I don't understand wordpress user registration spam. What's the point?
@Andrew_Taylor @mathsfeedback @ColinTheMathmo my ears are burning. Can I add a question to my survey? My vote says 10% = 0.1. It's a ratio!
@helen_keen @scienceatlife oh no! I was planning on going to see you tomorrow but you're on at the same time as @MathsJam!

@Andrew_Taylor @ColinTheMathmo now I need to find that page with the many many different ways people think of multiplication, don't I?
@Andrew_Taylor @ColinTheMathmo I can't find it! It was beautiful. It laid out each way of modelling multiplication (and numbers) so clearly
@C_J_Smith @peterrowlett @jan_e_grabowski more fair might be to say every time someone asks what's on the test, what's on the test changes
@ColinTheMathmo yikes. Twitter is not the correct medium for this.
@Jackg00de @LeedsMathsJam I don't know about Leeds, but I write up each Newcastle MathsJam on my blog: checkmyworking.com/category/maths…
@ColinTheMathmo it was by something like nRich, but not nRich. Maybe Australian?
@peterrowlett @ColinTheMathmo close, but it was a webpage and had like 12 or 16 models of multiplication

@ColinTheMathmo I can't remember! That's why I needed to look it up! Everything about this is frustrating.
@Tegglington but I'll know. I'll know. And I'm not convinced Collaborate won't interpolate the bejeezu out of the screenshots.

@EliotBall a bit too small. I'd prefer something the same height as a tick or cross

I am 100% with him. RT @maanow: Mathematician Objects to Platonist Patent System bit.ly/YvBvfq #mathnews
Having read the article, I retract my support of the patents dude. I thought he was going to argue maths shouldn't be patented!
@icecolbeveridge @stecks @standupmaths oh, that's a beautiful idea!
@Samuel_Hansen Congratulations! What are you doing?
@ColinTheMathmo @standupmaths @peterrowlett @icecolbeveridge @stecks how about something like jsfiddle.net/vRW8P/embedded… ?
Take an English word. Use its first letter as the key to a Ceasar cipher. Decode that word using that key. Still an English word? Bonza!

@Mathematical_A @ICMS_Edinburgh that's probably true, but GCSE maths 100% speedruns are a fun way to pass time. I'm currently sub-20 minutes
@Mathematical_A @ICMS_Edinburgh (I had to do something to make tutoring prep interesting)
@ICMS_Edinburgh oh yeah, absolutely. But it's fun to do in a few minutes something that took an hour when I was little!
@vickytnz no: you didn't use "chuffed". You might qualify for Southerner, but not generic British.

@henryseg that would be wonderful, thanks!

@Thalesdisciple this might be a British thing, but I've never liked that, and rarely seen it used, because it looks like a column vector.
@samholloway yeah, that's my opinion, but I've seen $_nC_r$ enough times that it made me wonder if there was some justification for it
really quite annoyed that spambots have found survey.aperiodical.com and filled the first question with 11,000 horrible sex adverts.
Weirdly, they haven't bothered spamming any of the other questions.
@lostinrecursion is that just the convention you're used to?
@lostinrecursion is there a rationale for either one? I'm used to the superscript one, and I think it looks nicer too
Having fun listening to this album while I work: youtube.com/watch?v=1_8zh4…
re: $_nC_r$ or $^nC_r$ or $\binom{n}{r}$: Imagine if there were this many different ways of writing exponentiation. We'd all go mad!
I can't find anything in Cajori about choose/pick notations. Dude was an amateur scholar
@ebuie a WHAT? Tell me more!
@tim_hunt haven't read that yet, but yes - zenzizenzizenzic is my favourite maths word
@ebuie @CannyCreative @RichardCarter I think what they're really advertising is the nitrous oxide used to whip the cream.
Where I can normally see the sea from my front door, today I can only see brilliant white. Am I in the Truman Show?

@DesktopGamer I think for kitchen measurements, the size of a cup is fairly standard: en.wikipedia.org/wiki/Cup_(unit)
@vickytnz did you find anyone to watch Eurovision with?
@vickytnz you can come out to Tynemouth if you like. I was planning on seeing the Late Shows, but I don't have the energy for walking
The best thing about these @aperiodical stickers I made is that now I'm making up excuses to send people things so I can use them.
not a single scientist at CERN has had the wherewithal to set up the "Euro Fission Song Contest". Poor show, science!
Does anyone have an opinion on whether eurovision has got worse or better over the years? Does that concept even apply?
YES! I managed to eat the melon before it went off! #homeeconomics
Like IQ? RT @DanielColquitt: @christianp I think Eurovision has its own scale of terrible-ness. Each year the scale is simply recalibrated.
@standupmaths @aPaulTaylor "modestly viral" - you are the common cold of internet sensations.

@mike_geogebra very nice!
how much is Gap going to spend on showing me ads before they realise I left their site because they don't sell trousers as long as my legs?
@icecolbeveridge that's not a demonstration of the central limit theorem. It's the binomial distribution. I can't see a quincunx either
@icecolbeveridge that's really weird. A Galton machine needs a triangular number of pegs
@icecolbeveridge CLT says the *mean* of the binomial is normally distributed over many samples, like any mean, but the normal approx...
@icecolbeveridge ... Let me retract that halfway. Binomial is repeated Bernoulli tests, so I suppose the normal approx does follow from CLT

@jjsanderson ooh, there's probably some maths you can do on the volume of the packet to decide that
@MadeleineS I've sometimes thought that, but a prescriptivist phone would be way worse to live with than a prescriptivist person!

@ebuie really? I have a friend who got as far as taking her theory test with no apparent problems
@ebuie I think @DVLAgovuk thinks you want to exchange your licence. You want to take a test from scratch.
@ebuie yes, US student, been here two years
@ebuie she failed it. I think she's going to try again though.

@NewcastleCC thanks!
Actually, 28/6 would be a perfect day for my Official Birthday, since my real one is so close to Christmas. If only I'd thought ahead!

@peterrowlett hooray!
@ant590 in what way?
@ant590 I think they switched over to their own system a week or two ago, so they're just using google for credentials now.

@mathpunk ... the public vote thing is open now, but if you send me a pick I'd certainly include it in the grand finale post
@mathpunk we're publishing the final post on the 29th, so until then
@mathpunk actually, having re-read your tweet: we're only looking at those six sequences mentioned at the end of bracket 4 for the final...
@mathpunk ... so can you pick a winner from them, and give a reason? If you have another sequence in mind, you could review it later on!
@vickytnz ah! I've been watching your Cardiff Quest tweets and assumed you had reasons for not flying. I should've said something.

@numberphile I thought the archive at bigprimes.net/archive/prime/ might have it, but it stops about an order of magnitude too early.
@numberphile they only have 1.4 billion primes though, so maybe 5,500,000,000th is an estimate from the x/ln(x) prime-counting function.
@numberphile I dunno either! The primality test says it's a proven prime, at least bigprimes.net/primality_test/

@vickytnz there might be a couple of mathsjammers having dinner at the Charles Grey. (not me though)
@ebuie @vickytnz you did, but I didn't send out the email until this morning because I've been away. Did you get it?
@jamesgrime you'll be able to name at least one former Canadian PM, so you should be able to pass as a local

@hornmaths diffing sin(x*y^2) with respect to x: looks like sin(A*x), A constant, so diffs to A*cos(A*x) = y^2*cos(x*y^2), by chain rule.
@hornmaths here's an example video my summer student recorded: vimeo.com/71901447
@hornmaths yes, with product rule, all of cos(y) looks like a constant - when you change x, it doesn't change at all
@hornmaths can you post a pic of your working?
@hornmaths ok, you don't need the product rule there - it's like you're just differentiating A*cos(alpha).
@hornmaths i.e. you don't have the product of two things that change with x
@hornmaths (sorry, with alpha)
@hornmaths glad you got it sorted. Alternately, if you were using the product rule, d/dx of cos(y) is 0, not 1.

@jamesgrime @peterrowlett @Wolfram_Alpha there was 1 silly comment before they realised we knew perfectly well what's going on, since edited
@jamesgrime @peterrowlett my guess is, fit assumes the points aren't on the line and interpolate uses something like Chebyshev interpolation
@jamesgrime @peterrowlett ... and because "quadratic through {X}" is most often used to fit regression models, it uses the "fit" algorithm

@DoctorLewney no, I'm 28 today, which is 14/1/14. 14+1+14 = 29, so I'm one off.

@evelynjlamb The first three differences are at n=99,101,535

@icecolbeveridge can't remember specifics, but sometimes superscripts don't need as big a bracket round them as \left( wants.
@icecolbeveridge i.e., technically the box is that big, but visually the bigger bracket seems worse
@icecolbeveridge similarly, you might want to force a bigger bracket if you've got a few in a row and only one with small contents

@robinhouston that reminds me that I had an idea for another method of making those from a source image...
@robinhouston start with all RGB tuples in a bag. Randomly pick pixels from the source image, and pick the closest RGB still in the bag
@robinhouston ehh, Python can shuffle 2^24 in a couple of seconds
@robinhouston oh yes, I was thinking of shuffling the pixels
@standupmaths apart from waste the rest of your existence at the infinity bridge?
.@robinhouston Here's an image where each component takes values 0-48
More allrgb progress: this picture has every 6-bit RGB triple in it exactly once

@evelynjlamb very impressed you got the shower working first go. I would've said that was the most obtuse appliance
@evelynjlamb ... unless it's a proper old-fashioned shower and not a new electric one
@evelynjlamb well done. And have you recognised the timeless brilliance of the British plug design yet? Maybe take a minute to reflect on it
@evelynjlamb they're gloriously over-engineered. It's basically impossible to electrocute yourself: the earth pin opens up the live pins
@evelynjlamb and once they're in, they don't fall out easily. Oh, and they run at a respectable 230V, not your pansy 120V
Oh dear, @evelynjlamb has accidentally got me tweeting panegyrics about BS 1363, the UK plug standard. It's just... so *good*!
I mean, every plug has its own fuse. That's pessimism about whether the device will function properly that other countries just can't match
This is also a good occasion to point out that "safety socket covers" are the opposite of safe: fatallyflawed.org.uk
@evelynjlamb no, the fuse is in the plug itself. The switch is just a happy feature to turn the supply on or off.
@evelynjlamb honestly can't imagine why it isn't standard everywhere. Do you just unplug things when you don't want them to be on any more?
An ostrich running inside a rotating tesseract. I don't know why. publicdomainreview.org/collections/te…
@evelynjlamb some houses have them, but yes, mainly hotels
@Sara_Tindall crikey! I hope one is a less pressing concern than the other.
@JPickford they'd have to be kicked out, and I don't think there's ever been a plebiscite to *lose* territory
@aPaulTaylor @evelynjlamb I'm sure you'll be gratified to learn that your remark is new to the conversation
@wilderlab I don't get it. How does addition work? Is KING [11,9,14,7]?
@wilderlab ahh, so a word's value is just the sum of the letter values
@wilderlab CAN+LEAVE = TRIP
@standupmaths taking corporate personhood in the other direction, eh?
@evelynjlamb and remember that 20% sales tax is included in prices
@mathhombre yes, we use "and"
@mathhombre why?
@LearningMaths @mathhombre @evelynjlamb @divbyzero whaaa?!
@woutgeo @mathhombre @evelynjlamb @divbyzero @LearningMaths we'd solve that by writing one-hundred-and-seven thousandths for 107/1000
@mathhombre @robinhouston "X hundred and (Y<100)"
@LearningMaths @mathhombre @woutgeo @evelynjlamb @divbyzero X=Y+Z, Y=100*N, Z<100. Pronounced "Y and Z"
A work-in-progress post about a cool thing I'm doing with pattern-matching syntax trees: checkmyworking.com/2014/06/patter…
@robinhouston not TimeCube, but unnecessarily obsessed with patents
@robinhouston like, nonstandard analysis isn't new, and he isn't making any wild claims that I can see, he's just obsessed with awards
@TimandraHarknes @elinoroberts As long as it hasn't got "To <student> with love, from ∫ cos(x) dx = sin(x) + C" engraved on the side, yeah
@robinhouston ahh. That's quite likely, but very different from TimeCube
In Chrome's javascript debugger, is there a more convenient way of breaking on a ReferenceError than "try{thing;false;}catch(e){true}"
@robinhouston on closer inspection, yes: it's hypercomputation nonsense that doesn't actually say anything
Has it really been ten years since the 80s revival?
@hellogeri the number 16 is just fine, and it's way cheaper than the Airlink/Aircoach buses
@icecolbeveridge you explained what the symbols stand for: instant disqualification
Oh, big sweaty poo! I forgot to commit the code I wrote at home last week. I'd better find something else to do.
Man, I thought this was going to make me rich, but MIT got there before me: museumstore.mit.edu/product/what-h…

Tonight is @MathsJam night! 7pm in pubs around the world. Find your closest one at mathsjam.com/closest-mathsj… I run the Newcastle one
@peterrowlett I tweeted that a few days ago. Not sure I can add to it, but I should look into resurrecting the questions site!
We have unary minus, i.e. "-2" is the same as "0-2". Why don't we have unary division, i.e. "÷2" could mean the same as "1÷2"?
@sqrtnegative1 @evelynjlamb not really: that still involves another number and a binary operation
@samholloway x = 1x?
@JamesMoosh the notation isn't
To those saying "but x^{-1}": I'm talking about notation! Of course you can make any binary operation unary by filling in one of the numbers
.@samholloway If we taught kids "÷2 means 'a half'", they'd accept that, like "3½ means 'three and a half'"
.@samholloway and my point was that '÷x' is not a convention. Just interesting that notation didn't develop that way
OK, duly decided: I'm writing unit fractions as ÷x from now on. Inform any future correspondents.
@evelynjlamb no new notation since 1962? This page needs expanding!
@Electrokittie and what you've squeezed out of you
@Electrokittie in fact, that handle would still be valid if *she* worked for the RAF
@Electrokittie yes militarywiveschoirs.org
I've finished my post about pattern-matching syntax trees: checkmyworking.com/2014/06/patter…
@axiomsofchoice yeah, it's more complicated than that. I'm familiar with rewriting systems
@axiomsofchoice or, it's exactly as complicated as that, but I have further requirements
@noneatnamesleft yep, except for 2/3: they only wrote sums of unit fractions maths.surrey.ac.uk/hosted-sites/R…
@peterrowlett unintended impact of your unintended impact article?
@RealityMinus3 then what's '-x'?
@RealityMinus3 that's what I'm getting at: why didn't the same convention arise for division?
@OddballDave ow it hurts my brain!
@OddballDave my best so far is 29
@OddballDave 38, and I've just realised the star and circle are supposed to be different colours
@OddballDave 44! So are they actually the same colour? I'm colourblind so I have no idea
Wow, google word definitions give a lot more information now!
I scored 0047 in @Psyclic_game. Ow ow ow ow my brains
gooeyblob.com/psyclic
@CardColm imagine if he'd peaked at age 3!
@ruimvieira I believe there are clubs for people into that kind of thing
@aoibhinn_ni_s your PhD has a word limit?!
@evelynjlamb I once watched my ferry leave as I was walking down the jetty. It's nice to have a bit of variety
@ejectamenta_com @MathsJam @NMSI @plusmathsorg are you aware of aperiodical.com/2012/06/wltm-r… ?
I've discovered the quick print button on the office printer. I reckon that'll save me a cumulative 10 minutes or so by the time I retire
Found a groovy book in the school library
@evelynjlamb be my guest!
@evelynjlamb I am prepared for a torrent of "I don't like change!" comments on that post
+1 nail on the head RT @evelynjlamb Yes, it's about notation, though: when we see -2, we think of that as a number, when we see ÷2, we don't
I expect the authors to file a copyright suit: RT @sxpmaths: @christianp 10 PRINT "BASIC statistics " : 20 GOTO 10 !
@haggismaths happily, there is! mathprofessorquotes.tumblr.com
@divbyzero I can see it!
@jjaron that's quite a low-poly x-ray
Stupid question time: is p^n*q^m ever smaller than p^n+q^m? (p,q primes, n,m natural numbers)
@tim_hunt yeah, I got that but left the tweet up in case I was being doubly stupid. Glad I'm not!
So it turns out writing randomised questions about permutation groups is quite hard.
@LargeCardinal @JamesMoosh none of the MO threads turned up when I searched, only M.SE. I'll look now...
@LargeCardinal @JamesMoosh yep, couldn't find anything on MO apart from one closed thread with nothing useful in it. Interesting!
Just realised the way I do division in my head is completely different to the way I do it on paper. Maybe the paper method needs more RAM
Considering making a Panini-style maths sticker album
@LargeCardinal ta!
@icecolbeveridge currently stuck on which platonic solid to make a shiney
Moving offices, I'm reminded again that recreational maths is a solved problem.
After being asked to improv it at a few minutes' notice, I've put the slides for my ~GCSE-level Herschel talk online staff.ncl.ac.uk/christian.perf…
@peterrowlett yeah, for me too! I wonder what's going on
@peterrowlett Chrome didn't like something about SVGs not from localhost. Bizarre. I've changed to PNGs
@ncllibsage @nclroblib just in time! We were just saying yesterday we need an updated library video for our first year induction material
@ncllibsage you are correct in your supposition! Thanks
.@evelynjlamb that thought could go viral if you make it needlessly specific: every fibonacci number is within 1 of a multiple of 3. Try it!
@Electrokittie ... freckles can be quite nice
@stecks @aPaulTaylor @evelynjlamb two mancs and a yank... what am I letting myself in for?
Happy birthday Alan! (a little bit late)
Did you know there's more than one Newcastle? Newcastle-upon-Tyne, Newcastle-under-Lyme, Newcastle-in-one, Newcastle-versus-Predator...
@noneatnamesleft yes, they had a big meeting in our civic centre a couple of years ago

@evelynjlamb Sir John Soane's museum is great soane.org
@evelynjlamb and you'll probably like a choral service at St Martin's in the Fields stmartin-in-the-fields.org
@evelynjlamb not necessarily! St Paul's is a lot bigger, after all...
Coo! A physically universal cellular automaton web.mit.edu/lrs/www/physCA/
@tim_hunt oh no, that's awful! PHP strikes again
Hm. Even though it involves the primes, I thought I might have had a winner with this one. Poo to you, Labos Elemer!
@ColinTheMathmo I dm-ed you, or so I thought. I'll email. Colin@solypsis.co.uk?
Writing worked solutions to randomised questions: aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
@Derektionary @OnThisDayinMath @wilderlab there are no numbers such that x^3 = (a)(a+1)(a+2) for x<60000000
@Derektionary @OnThisDayinMath @wilderlab hm... time to start the Online Encyclopedia of Impossible Sequences
I'm finding it surprisingly tricky to find an x^n that forms an arithmetic sequence when you split it into equal-sized chunks
@MathJax @janmarthedal oooh! Nice.
@CardColm we've crossed paths! I'm in London today. So sad we couldn't meet up
@jamesgrime what's its impact factor?
I'm doing a suspicious amount of work on my day off. Might not get any lounging done before lunch at this rate.
@aperfect ah, the old `/fov 150` trick
Email, received today: "hello what is a computer i have lived these past dozen years in a swamp" (paraphrased)

@lyd_w I always wonder how Americans can be so enthusiastic about bacon when they don't even eat real bacon
it's been a while since I unzipped a local copy of MathJax on windows. Takes about 40 minutes!
@icecolbeveridge I had a similar problem this weekend! Except I have an octagonal bay window into which a hexagonal play pen will fit
@icecolbeveridge the playpen is in the post - we'll see!
Most unusual capitalisation of @NclNumbas yet: 'NUMBAs'. What could that stand for?
@MarcusduSautoy are you absolutely sure that it's *all* down to that?
@standupmaths my brother @aperfect has a photo (taken on my instigation), but maybe shouldn't be named in the book?
@standupmaths @aperfect haha, then I suggest "the least visually appealing of the Perfect brothers, Adam". He's in San Fran at the moment
@standupmaths @aperfect and the photo doesn't seem to be on his flickr page, so we'll have to wait for him to wake up!
@ashleyhwright I've been watching it with trepidation, but I've never had JISC funding so it doesn't affect me directly
@ashleyhwright indeed!
@kirel Hooray! I hoped that sprite earlier meant you were working on detexify again. Feedback: drawing erratic on Android; hard to scroll
@kirel nexus 4. Seems to lose the touch event, maybe as results load. Scrolling hard because the drawing takes up most of the screen width
@peterrowlett @MarcioRdeGMaia Erm.. yes. Why wouldn't it be? It's on his official YouTube channel
@outofthenorm2 @peterrowlett @MarcioRdeGMaia thanks!
@jjaron that's prompted me to do some fun searches on Hansard, e.g. theyworkforyou.com/search/?q=%22I…
@JanvierUK if you find it interesting, it's fine
I've updated checkmyworking.com/misc/the-mathj… because the @MathJax CDN finally has the same URL for HTTP and HTTPS
@ColinTheMathmo yes, and I try to when you're near, but that isn't very often!
@plusmathsorg no, I do it too
Twice this week I've received letters from companies telling me they're giving me a discount... on their newly doubled prices
Hooray! I'm paying lots more for the same service, but not as much as you've arbitrarily proclaimed I could pay!
@CardColm that book seems to be everywhere at the moment. It's high up the maths puzzle chart on amazon
I missed 44444 so this'll have to do
Wait! Even better: now it's 3:33
@ChrisMaslanka @hughhunt I'm interested in making someone do a big enough fart to get empirical data about this.

@jamesgrime yes! There's often a lot more interesting stuff to talk about when you get past "here's why this is bad"
@haggismaths eugh.. I *still* haven't posted about this on the @aperiodical. Can I just say everyone's seen it now, and forget about it?
@jamesgrime PS your review is very good and thanks for letting us publish it
Working on making it easier to change things like the logo in @NclNumbas tests... #genuinedevelopmentscreenshot

@MARitchings correct!
p5.js is very similar to the old Blitz languages, so I'm converting over some of my old things for fun somethingorotherwhatever.com/swirlograph/
@MARitchings no, just came up with the question :)
@haggismaths gosh! I wish @NCLMathsStats paid as much attention to the interior decor of the maths department
@Gopesh_Krishna @MARitchings in base b, 1248 = 1*b^3+2*b^2+4*b+8 = (b+2)(b^2+4). If that's a power of 2, then each factor must be also.
@Gopesh_Krishna @MARitchings yes, what's wrong?

@robeastaway arg! What's the point in long division?
@theoremoftheday I learnt poly div having never known long division, and I find it way simpler. Long division needs lots of lookahead
@theoremoftheday @robeastaway (I mean, I was shown traditional long division in primary, but I did what I think is 'chunking' instead)
@ColinTheMathmo @robeastaway @theoremoftheday for me, it often boils down to "divide 3-digit number by 2-digit number, but in your head"

@tim_hunt yeah, but that involves a line of debaggage at the start of each function
@lyd_w no matter what band it's for, that director always does the same quick-cuts-naked-ladies-plus-weird-stuff video
Do you think flies have nightmares about eating so much they can't take off? This one is nearly there.

@DameAllans I just got an email asking for volunteers to talk to RGS's new maths society. As a DABS alumnus, I couldn't possibly!

@FOTSN interesting date order on that page. Sorted by month?

@MathJax convenience when I just want "some mathjax". Like wordpress.org/latest.zip gets me the latest wordpress
@samholloway an Alfa Romeo mechanic, yesterday: wired.com/2013/09/absurd…
@MathJax it works! Thanks!
@eqdynamics probably no quicker than me - it just requires a lot of pasting command line stuff because there's no install script

@standupmaths Dim fun = 0
Just made a git commit whose hash starts '4444'. I wonder if I can search github for a commit with five repeated characters

@Kex92 @MathsJam not my handwriting!
It's 10:24! Binary dance party! #mathsjam
@WoollyBenguin @MathsJam no, exactly the point I made! "-3" means "negate 3". Or, "additive identity minus 3".
@peterrowlett @ajk_44 @KathrynHTaylor I only counted three women: Katie, Alison and Noel-Ann. Who did I miss?
@drbhind @peterrowlett @ajk_44 @KathrynHTaylor @haggismaths ah yes! She isn't on the website because she only offered her talk on the day
@nikoletta_tk I've been told you have a "better" solution to the princess in a castle puzzle. Very intrigued!

@FOTSN wot no SCI HARD 4.0 (TO 1DP.)?
@FOTSN I just hope you can make a t-shirt big enough to cover my, to quote @standupmaths, "ridiculous shape".
@FOTSN @standupmaths in that case I demand one made from alpaca wool (but not from the Penrith Alpaca Centre)
@FOTSN but there was a bit where a fighter jet does a doughnut around a motorway overpass and maybe you could put that in your next show
@drbhind super! You've already got an account, haven't you?
It's 12:46! Thanks to the #mathsjam attendees for giving me a reason to celebrate it.
My favourite non-maths 1246 fact: it's the country code for Barbados.
@sam_james30 how many? How many maths?
Wanted: something like git's merge algorithm, but on JSON objects.
@haggismaths well, 10 is less than 14 so maybe 10^10^10 isn't that far off
Hah, underneath the ISBN in @standupmaths's book is the checksum.

@icecolbeveridge nope... you haven't got ASCIIMathML input turned on, have you?
@peterrowlett yeah, I have done, but the decision about how much I'm paid is made many levels up
@icecolbeveridge can you show me the page?
@icecolbeveridge that's a unicode times symbol in the source, not an x.

@alexbellos slightly odd request: do you have a link to the video of that time you demoed the cake division problem on Brazilian TV?
Sold the dog a meta-dummy: faked throwing the ball so many times that when I did throw it, she refused to believe it and looked in my hand
@alexbellos my line of thought was "fair division problems are hard... didn't Alex Bellos tweet a video of him doing bad things to a cake?"
@Beamish_Museum worked it out on my correntator. Easy!

@tarim8 @ColinTheMathmo @joindiaspora @samholloway I'm sure it's possible, but the resulting tweets would be unreadable.
@tarim8 @ColinTheMathmo @joindiaspora @samholloway anyway, the problem is getting people to write stuff on the diaspora site

"100% chicken breast". I wonder how the bacon feels about that.
@icecolbeveridge @nillie_kj huh? No, I was just planning on writing C=180-A-B and getting on with my day
@robinhouston in what way? I can see a couple of problems
@robinhouston ok. It also goes down between 2005 and 2008. And which average do they use for CEO pay? And why $ versus £? etc etc and so on
@robinhouston "read more" says "even proportionally, there has been almost no improvement in poverty rates in sub-Saharan Africa since 1981"
@haggismaths aaa I want to play!
You know that sandwich I tweeted about at lunchtime? It is now making me pay for my insolence.
What I'm trying to say is:
Poopin'.
@TimHarford I certainly agree with the headline.
Cool kids don't link directly to the PDF form of an arXiv preprint
@kenfodder code, or prose?
Recently we switched to a brand of bread whose slices don't have reflection symmetry. This has had bad consequences for our sandwiches
@semiBad I sometimes shush command line tools
@Gelada Butter both slices. Add filling on one, flip other and put it on top. Solved by flipping one first, or not buttering both sides
@samholloway what about Qs F,G and H?

@ben_nuttall can I do a twitter pull request? s/'lol'*i/'l'+'ol'*i/
@mutedestro huh? You prefer linking directly to the pdf?
@mathcentre thanks, but this is very much a personal account. Can you please mention @NclNumbas instead?
Going to assume the fact my DSL has gone down is linked to the digger outside. There's some shouting.

@mathhombre I'm writing a thing about this for @aperiodical. I have largely the same thoughts
LMS/LMS mashups:
Least Mean Society
Least Mathematical Squares
London Mean Society
Trying to just post a nonsense formula piece without digging into it and cataloguing the many ways it's nonsense. Failing.
The @aperiodical is doing really well with guest posts at the moment. Thanks everyone! And if you've got something to say, send it in!
@peterrowlett sorry...
@peterrowlett but I'm working through the news queue! Pity that my dealing with administrivia produces yet more of it

@JanvierUK the BBC programme page only goes up to 5th of Feb. Where else would one find it?
@Derektionary I'll consider that definitive!
@GreyAlien wow, you're really splashing that indie cash
You all think you're so cool, with your links in red and no underline. Well, I'm not clicking on them because I can't see them.
Has anyone compared Apple's record profits to the East India Company? Time for Obama to take them over and become Emperor of Bevelled Edges?

@tynesidecinema not sure if it's appropriate for Valentine's, but Umbrellas of Cherbourg

@JamesMoosh yeah well, I wrote left-to-right and didn't think about what would happen after
@ashleyhwright oh wow, you're right! Glad I'm not going out for lunch today
Today's notation conundrum: is "5/7" a mathematical expression which must be calculated, or does it represent a number in its own right?
I'm of the opinion that, for example, "10^9" is a thing to be calculated. But I'd almost never write it as "1000000000", so maybe I'm wrong
Maybe the question is: is this how you'd write this number if you referred to it on its own?
@jjaron it's one more than 56.
@jjaron quite!
@icecolbeveridge I think there's (one or more) way of writing a number so you say "I don't have to do any more work, I know what this is"
@icecolbeveridge you're slightly veering away from my question - not "what's the best way of writing it?", but "does it need any more work?"
@infrahumano so my question was: does "5/7" represent an operation, or not?
@AdamCreen I consider a GCSE marking scheme the least authoritative possible source

@Andrew_Taylor I think "it" is the benefit from doing the thing

@nclroblib when I'm on sciencedirect, the library's logo is not showing up - it's trying to load from ncl.ac.uk/library/findit…
@nclroblib that was the point! I was looking at sciencedirect.com/science/articl… and the URL I gave before is where it thinks the logo should be

@walkingrandomly yeah, that's not a problem. But github provides a lot of useful stuff that would be hard to replicate if they disappeared
@leonpalafox @walkingrandomly that's a bit different, because you don't typically keep a local copy of all your emails
@leonpalafox @walkingrandomly I'd say it's more like google reader - they added a lot of value to something that already exists freely

Over two years in the making, all three parts are now online.
I work a 4-day week, for medical reasons. I took a 20% pay cut, of course. But I reckon I'm as productive as anyone else working five days.

I've watched SEVERAL videos of frozen pea factories on YouTube and I still don't know how they get them out of the pods.
This Pathé film has a lovely jazz soundtrack though youtu.be/BL_xPZzSd8Q
I don't think Mr. Pea Sheller is the answer youtube.com/watch?v=Pk9arl…
This chap is also proud of his homemade pea sheller. youtube.com/watch?v=6bTRO6… In other news, American peas look weird. Are they really beans?
@evelynjlamb Mr. Pea Sheller is the answer to a different question
@evelynjlamb we call big ones 'garden peas' and small ones 'petits pois'
@evelynjlamb I think so? Don't make me do more googling, Helen's already had enough pea factoids for one morning
In conclusion, peas is a land of contrasts. Thank you.

@divbyzero @katemath (lost track of the replies thread) - that blog could absolutely go in the @aperiodical. As infrequent as you like :)
@brittneybean so by implication the other parties have bigger black holes, or the IFS expects the government to change their spending plans?
@MouldS what does "opposite" mean, if the face is not a regular polygon?
@MouldS do you want a vertex to be on the normal out of (your choice of) centre of the face, or just inside the polygon when projected down?
@MouldS wasn't there a reason the trick for general polygons doesn't work on polyhedra? Otherwise, a method to make them is pretty obvious
@MouldS given an hour or so with a 3d modeller tomorrow I reckon I could have a go at one

@jjsanderson that's my plan
This morning: booking in a hip replacement, keyhole heart surgery and some depression therapy while they're still free
After that, off to the pond to pick out the swans I'm going to buy on the cheap when they're privatised
Hard-working families can still look at my swans for free, or now they can join Swan Plus+ for a fee and feed them anything they like
I'd like to reiterate that should I win the swan franchise, I have no plans to sell them to a French butcher and replace them with mallards.
Yes I have advised the government that demand for swans is at a historic low so they should be priced accordingly, but there's no conflict
The part of my personality which independenty advises the government about swans and the part that wants to buy them are completely separate
still tweeting nonsense about swans to distract from the dystopia
The law to forbid geese and all waterfowl other than swans from using Britain's waterways will be a key plank of the government's programme
Obviously nobody will buy the swans if anyone can just look at a goose, which is basically a short fat swan, for free
In order to protect swan owners' investments, I have advised the government to allow them to impose a charge for looking at swans
Britain's benefits claimants are workshy scroungers. That's why they'll be required from June to show they've looked at 5 swans each week
Oh god, they're actually going to sell off the swans, aren't they? I don't think I can be hyperbolic enough today.

@robeastaway @curious_nick "real world maths"
After too long playing the others, I've made my own numbers-in-a-grid game. It's about sequences christianp.github.io/sequences/
@theoremoftheday any arithmetic sequence will do. Doesn't matter where the numbers are in the grid
@theoremoftheday yeah, I can't think how to word it without using mathmo terms
@mutedestro Use the number which is your current level (ie to move to level , use a 5)
@noneatnamesleft yes :)
@noneatnamesleft or if you get 1..n and n is your current level, it's n^3. Might get rid of that - it was better in an old version
@noneatnamesleft indeed. I was surprised how little tuning it took once I noticed that was a good tension
@noneatnamesleft no, it doesn't. Interesting question if it's possible to have no legal moves - difference of 0 is allowed
@noneatnamesleft something something Tao-Green theorem? I know @TweetsofCushing spent a long time thinking about progression-avoiding sets
@ronalddotgl @noneatnamesleft you could if those were all on the board
OK, it looks like the game is playable to non-me humans. Here's a target.
@jiyameng 24 (if you reload the page, I've just added the level to the game over screen)
@jiyameng use your current level number in a sequence
@noneatnamesleft sadly, no
Oh my twitter.com/jiyameng/statu…
@ronalddotgl well done :)

@thomas_bland @jiyameng hm. I'm still missing a key ingredient
Nearly! @thomas_bland @jiyameng
@jiyameng @thomas_bland I tried, but didn't have enough moves left. This was my last move
I've added (local) high scores to #sequencesgame christianp.github.io/sequences
@jiyameng no, I'll add one
Wahey! I'm feeling good about this one @jiyameng @thomas_bland

@elinoroberts for some reason I read that as "aurochs watch". Not sure why. Very different.
The Dutch are lovely but when they talk it's like this youtu.be/FcUi6UEQh00
@robeastaway to some more decimal places, the rate required to lose 50% is 2.734% per year, so it's not so bad to round down.
@robeastaway and 2.34 leaves <55%, which you couldn't be blamed for rounding off to nearest 10%. So double rounding error is to blame
@robeastaway well yes, I did think of that but hesitated to say

Challenge: label train carriages so that it is easy from any position to work out which way your carriage is, relative to the nearest
A, B, C, D,... is no good because is A at the front or back? And where's the front?
Maybe segments of a wedge - thick end at one end of the train, thin at the other, so one carriage's symbol points to the thin end
How do you refer to that though? Maybe do the same in letters: carriages labelled AB, BC, CD,... except the other side goes DC, CB, BA...
@icecolbeveridge yeah, that would also work. But I'd like what's on the ticket to match what's on the carriage
@icecolbeveridge so can we think of an ordering in space that doesn't bring to mind direction of movement?
@icecolbeveridge yeah, well, if you're adding embellishments, you can just draw little arrows labelled with the other carriage letters
@icecolbeveridge oooooh, VERY nice!
@icecolbeveridge yes, the ordering needs to be independent of the direction of travel of the train. That's the whole problem!
Unexpectedly at East Midlands Parkway. They've erected a hyperboloid in my honour. Good work!

@C_J_Smith someone did some maths for the Robert Downey Jr film a few years ago newscientist.com/blogs/culturel…
@icecolbeveridge "The research, commissioned by" appears in... the third paragraph! That's earlier than usual
@icecolbeveridge actually, searching for that phrase is a good way of finding nonsense PR stories google.com/search?hl=en&g…
@icecolbeveridge my wife's a massive Poirot fan. I sort of feel like doing this properly
@JanvierUK lies!
In the English language, does the letter K have a silent majority? Or is it pronounced more often than (k)not?
@samholloway anywhere. There are word lists with the kind of data you'd need to answer this, but I don't know how to use them
@ChrisMaslanka good question. It's not really the kind of thing I was thinking of there, so no
@samholloway corpuses and wordlists exist in that weird half-open world of "email these academics and we'll give you access". Hard to use.

@ColinTheMathmo if you can track down "enlightening symbols" by Joe Mazur, there are good examples in there
@ColinTheMathmo (it's a cracking read anyway, and does a really good job of pinning down the evolution of algebra)
@MEIMaths that doesn't seem to be in the OEIS! Do you agree 1000-01-03 is the first prime number day?
@MEIMaths is there a way of linking just to this item of the month?
@ColinTheMathmo if I remember when I get home, I'll try to scan some in for you
@ColinTheMathmo and of course, if you ask Singmaster he'll have thousands
The 29th of February 2028 (20280229) will be a prime number day. SO WILL THE NEXT DAY, the first of March (20280301)!!! @MEIMaths
You can make an arithmetic out of this, right? Bonus points for working out what it is
@ColinTheMathmo yes!
@poveryant @MEIMaths very nice indeed!
@ColinTheMathmo @JSEllenberg I'll guess it's an automatic script that inserts the conversions
@alexbellos @mathemaniac @BioGraphica1 I've philosophical objections to the no fractions rule. They're in there even if you don't see them!

@ben_nuttall I'd always go for dict.get or dict.setdefault. Say what you mean, and so on
@ben_nuttall that's what setdefault does. What else do you need?
@ben_nuttall a = dict.setdefault(b, lookup(b)). I suppose if lookup has side effects that's bad.

@icecolbeveridge oh, do you not have a tiebreak in the fifth set? How does it work?
@noneatnamesleft I've identified all odd-numbered tiebreak points, so I suppose I'd do the same for the fifth set
friends, it's becoming obvious I don't know tennis very well. I'll get rid of the fifth set tie break
@aPaulTaylor @icecolbeveridge yes, that's what wikipedia is telling me
OK! I've got rid of the fifth set tiebreak. But now I have lines intersecting circles, which I'm not happy with. checkmyworking.com/misc/tennis.svg
@icecolbeveridge hmm. Maybe. I prefer a finite graph.
@icecolbeveridge and also, I'd have to draw a filled triangle for all the lines that lead to the next set
@icecolbeveridge no, but if you identify "advantage" points in tiebreaks, you can make a finite state diagram
@icecolbeveridge they do.
@icecolbeveridge hmm. If I'm doing curved edges, I might as well keep it as I've got it

Leaving my office for the last time before big @MathsJam. How many things have I forgotten to pick up?

@theoremoftheday is that the smallest number not in the a-line of a sequence in the OEIS?
@icecolbeveridge @theoremoftheday depends on what you mean - everything's in implicitly because the natural numbers is in
@icecolbeveridge @theoremoftheday but each sequence lists ~240 characters as its "A" line, so later terms don't show up in search
@icecolbeveridge @theoremoftheday or, if I parse your question differently - I guess that sequence starts at 14972 and gets dense quickly

TeX might be Turing complete, but that doesn't mean it's possible for *me* to make it compute any function

@mathforge yeah, but I'm making a system that's supposed to integrate with any lecturer's notes. Some are still on vanilla TeX!
@mathforge ... yes
@mathforge thanks. I feel like I'm just missing one simple idiom for what I want to do. If I could spend a day fiddling about, I'd have it
@mathforge it's to do with reading label definitions in from an aux file, then writing something else out to a different file
@mathforge my line of thinking is, leave parsing TeX up to TeX, and write out something in a format my other tool can use
@mathforge oh no, the external tool is the destination. I take in tex files and need to give the other tool a list of labels in the document
@mathforge anyway, I got it working hackily earlier, but I'd like to see if I can do it better

Success! (#spoilers)
@C_J_Smith that's some good dadding!
Yesterday I got the computer to decide if a number is prime, today it is YOU who must decide! isthisprime.com/game/
@KristianStill done! Add ?max=N to the end of the URL, e.g. isthisprime.com/game/?max=50
Teachers who liked the prime game: I've added an option so you only get numbers up to a certain maximum. E.g. isthisprime.com/game/?max=50

@mscroggs @chalkdustmag @icecolbeveridge put me out of my misery. Chess is rubbish.
@icecolbeveridge yes, I think: I pick random # and give to you to add to your answer and hash. You send hash back and I compare with mine
@icecolbeveridge e.g. md5(colin+n) = md5(cp+n)
@icecolbeveridge well, if the hashes disagree then that just says your claimed answer is different to mine. If you lie, what's the point?
@icecolbeveridge I don't give you my hash
@icecolbeveridge we could make mine symmetrical by sending each other numbers to add
@icecolbeveridge OK, I'm ready to check we have the same sum of across clues
@icecolbeveridge right, my hash is f581d1f504c23bfc2d5e6a6715f03d41. (And for sanity, the hash of "1" is c4ca4238a0b923820dcc509a6f75849b)

@kaysuza @ColinTheMathmo I'll see if I can do a drawing or video at lunchtime
@ColinTheMathmo my method eventually falls foul of the "can't fold over more than X times" rule of thumb. Sound familiar?

@Pyfagorass not yet. I know I get into Jo'burg in the morning and have to do things at Pretoria Uni in the day. I leave SA on the 23rd.
@Pyfagorass is Pretoria close enough for you to travel to just for the evening?
@aperfect I am indeed! Doing training at the university
@aperfect 16 hours each way though. Horrific.
@icecolbeveridge several sub/sup brace errors around the sums. #texsupport
@aperfect first flight is via Paris with 4 hour layover so 2h+10h30, second via Dubai for 2 hours, so 8h+7h40. :(
@aperfect nope. I don't have trouble with noise on flights, just my legs!

@MouldS which other letters' dot matrix glyphs are subsets of another's? Could have some fun with this

@robinhouston @JDHamkins @NemoPublius so, I was going to say the same sequence backwards, but the question asks for three integers

@mike_geogebra no dice. This is just a worksheet with some axes in space, embedded in a page. Dragging just scrolls the containing page.

@RobJLow how does sitcking a % on the end of a number differ from sticking 'cm' on?
@RobJLow yep. But it changes the meaning of a number in some other way, while acting a lot like a unit
Next question: when does % vanish? Sometimes '4 times 20%' is '0.8', sometimes it's '80%'. What about '40 times 20%'?
@ElzbthMcCrthy uh huh... but sometimes after multiplying a percentage you're still talking about percentages, and sometimes not

@icecolbeveridge but what about kids who don't know 'integer'? Is this a losing battle?
Am I on the right side of history by saying 'whole number' is a synonym for 'integer'? If kid rounds -2.3 to 1, they learn a valuable lesson

@RobJLow ... so?
@RobJLow yeah, I abused notation
@RobJLow maybe: roll a 3-sided die. I say "something a 1/3 chance of happening happened once" with probability: (?)
@RobJLow the difference is whether you're watching for a *particular* thing to happen 10 times, or any one thing with prob 1/3 to happen 10x

Link in the post goes to NYU, which I can't see
@NYULibraries I don't! Thanks though. Is there a URL the post author could have used to show non-privileged people metadata about the paper?
@evelynjlamb Read the paper, I'm even less happy. Better stated as "no correlation between weight and poo time". Observed times between 2 and 27 seconds!
@NYULibraries I've got a copy now, thanks. Showing what I've been directed to before asking for a login would be good UX.
@haggismaths And here's the paper itself epubs.siam.org/doi/abs/10.113…
Is there such a thing as cat's cradle with two strings? (or, in this case, laccy bands)
@icecolbeveridge huh? It's just a sign error: -10T=-17.5T etc. means distance travelled is in the same direction as initial velocity. Should be -10T=17.5T...
@icecolbeveridge and the acceleration is in the same direction as the distance travelled, so should be negative. Who sold you this formula? Get a refund!
@icecolbeveridge ah, I used u and didn't spot you hadn't. So is it a coincidence that 5/7 turns up both ways round? I'm lost in a maze of signs
@icecolbeveridge That's what I first thought, but I convinced myself it wasn't quite it. I think I meant changing v without changing u or s, but that breaks
@GirlGeekUpNorth @ben_nuttall @Raspberry_Pi Is that photo of @ThinkPhysicsNE in Northumbria Uni? I got excited and then noticed the event is in Manchester :(

@reflectivemaths @srcav @icecolbeveridge The most charitable I can be is to interpret "x^2 - y^2" as "x^2 to y^2", and the factorisations would range from x*x to y*y.
Did I dream about voting yesterday, or has BBC News forgotten that North Tyneside had a mayoral election? bbc.co.uk/news/topics/42…
Oh look, an article titled "Council and mayoral elections: Are they being forgotten?" on... BBC News!

@peterrowlett @icecolbeveridge @reflectivemaths in that case, [stuff] would be "this part of the expression"
@warwick_hunt79 But there are "not yet declared" entries for other elections
North Tyneside maybe-a-dream-election update: our (good) Labour mayor was re-elected with a swing away from the Tories. Hooray!

As an academic, my pay offer this year is 1.7%, while my teacher wife's is 1%. In 29 years, my 0.8 FTE salary will catch up with hers
(ignoring pay scales, and assuming the rates of increase stay the same, which they defo won't)
But thanks to inflation at 2.9%, our combined pay will by then only be worth 64% of what it is today
Supplementary question: have I given enough information for you to work out the ratio of our salaries?

I think now is the time to write a @NclNumbas extension which gives you a random name and pronoun, picking uniformly from gender and culture twitter.com/ajk_44/status/…

@Andrew_Taylor deprecated in ES2017
@Andrew_Taylor I just meant the message is deprecated...
@Andrew_Taylor a linter is like someone who insists on applying Latin grammar to English. Once you know enough to be confident, safely ignore.
@Andrew_Taylor but I would recommend looking for a way of doing things that doesn't involve extending built-in prototypes
Rejecting the gender binary is leading me down some funny paths, such as this stackoverflow question stackoverflow.com/questions/2161…
OK, how about this? Have I got the rule for gender-neutral verb conjugation right?
@DavidKButlerUoA @samholloway @ajk_44 I wrote this in the readme to the extension. There are more categories than just gender, so let the computer take it out of your hands
@DavidKButlerUoA @samholloway @ajk_44 Furthermore, if you only ever use gender-neutral names, they can feel artificial. Sometimes the surgeon *should* be called Chantelle!
@DavidKButlerUoA @samholloway @ajk_44 Oh sorry, I ended up writing an extension to @NclNumbas which picks random people for you github.com/numbas/numbas-…

@RobJLow @panlepan ahh, but five rows of holes. Looks more encouraging now
@sxpmaths ooh, now I can't look at it an not want them lined up
@peterrowlett I'm going to be pedantic! Things become less true when we generalise axioms, e.g. anything following from the parallel postulate
@peterrowlett no, but "lines cross once or never" is a different statement to "lines on a Euclidean plane cross once or never", though... (1/2)
@peterrowlett ... people before non-Euclidean geometry would've been happy saying they're effectively the same
@peterrowlett right! So theorems don't always stay as big: by generalising, the part of the mathematical world they apply to gets smaller
@peterrowlett my point is that Euclid's axioms were the only game in town. I'm getting at the idea that something that always applied becomes less so
Not a day goes by that I don't internally thank @peterrowlett for asking for the 'except' operator in @NclNumbas
@peterrowlett stick that on your REF
@be4zley @kevinrutherford Yes. I had half a thought that you can concoct some kind of 'derivative world' with base unit per-seconds, where it isn't dimensionless

Uni is collecting data on disabilities so it can comply with non-discrimination law: 😊
Form only lets you pick one disability: 😒
oh, it's a SAP form. Which means they've paid a huge amount of money for the form to be useless.
And it doesn't even save, anyway.
seems HR's solution is an option "two or more disabilities".
So the form might as well be a checkbox "I'm disabled in some way".
If someone's making the effort to tell you about their disability, why would you not want as much information as they're willing to give?
What can you usefully do to help, knowing that X % of your research employees have "a specific learning difficulty" (but not which one)
@JamesMoosh Quite. But this information won't help them comply, since they need to know exactly what's up so they can accommodate and adjust

Pick x,y.

b=a+x=2x+y
c=b+x=3x+y
d=c+x=4x+y
e=c-a=2x
f=d-a=3x
g=e/x=2
h=f/x=3
1=3-2
@DavidKButlerUoA @RogoNic If zero is a number, you need a first step to check x isn't zero by checking if x+y = y.

@WoollyBenguin such as?

@WoollyBenguin I agree about £0, 0s, 0d. '0' as a number is a different thing from including leading zeros.

Solution: holes a, b, c and d are mutually exclusive options for where the middle shelf goes. So you only need 6 of part D
If there had been fewer options, there wouldn't coincidentally been as many potential holes as screws in the pack (there are two sides)

A day late and in the wrong year, I've come up with a notation idea for #mathsjam: there should be a different zero symbol to show (lack of) precision.
e.g. 3xxx instead of 3000 when figure is correct to the nearest 1000.

or, since you're rounding after a particular digit, a separator would do, like 3~000
@HilariousCow Why it works:
If A and B are both >= 0, then
(1) A > B
is true if and only if
(2) A^2 > B^2
so if you check (2), then you also know (1), and vice versa

@DavidKButlerUoA @rak_1507 here's one: ssf!ssf!ssf, where s is square root, f is floor, and ! is factorial, evaluated from left to right
@DavidKButlerUoA @rak_1507 here's the python script I wrote to play about with this: gist.github.com/christianp/2bd…
@icecolbeveridge @MrChaconMath @DavidKButlerUoA @rak_1507 I've crunched the numbers and can do 4 in 28 steps: ssf!sf!ssssf!sssssf!sssssssf
By the way, I'm also delivering a workshop so you're all slowpokes
@icecolbeveridge @MrChaconMath @DavidKButlerUoA @rak_1507 It looks like no new values < (100000!) after 64 steps, unless some gimongous factorial would eventually collapse
@DavidKButlerUoA @icecolbeveridge @MrChaconMath @rak_1507 here's my python notebook:
gist.github.com/christianp/f8b…
basically, keep track of shortest sequences to produce unique values, and try adding operations to the end
@DavidKButlerUoA @icecolbeveridge @MrChaconMath @rak_1507 Yep. And only show values less than 10^5
@DavidKButlerUoA @icecolbeveridge @MrChaconMath @rak_1507 I have a sequence of operations to apply, e.g. "sf!" is "square root then floor then factorial".
If a long sequence produces a result I've already made with a shorter sequence, obviously no point in looking at it any more.
@DavidKButlerUoA Fairly easily done, since you've got the list of steps for each number. Missing cycles of course
@rak_1507 @DavidKButlerUoA @MrChaconMath @icecolbeveridge Ah, you're allowing non-integer factorials, aka the gamma function. Lots shorter solutions if you do that

@darrenjw I can make a devil's advocate case for them all being the same thing if you only look at multiplication: the product of any matrix with the empty matrix is the empty matrix
@darrenjw Only so that the result is well-defined. But here it is: it's always the empty matrix

How can you write a whole article about 'shrinkflation' and not look at price per gram?
Just saying that some products are smaller and some have gone up/down in price and joining the two misses the point entirely.

"While price cuts for products are not always in proportion to size reductions - it is not the case that customers are being short-changed all the time."
15 out of 19 sweets are worse value now. So by and large, customers *are* being 'short-changed'.

@OlafDoschke Yes, the hard part is putting them in order
little Easter egg: you can keep adding digits to the URL - three.onefouronefivenine.com/twosixfivethre… - but it'll give you a 404 if you get it wrong - three.onefouronefivenine.com/twosixfivethre…
I also made these slides to go with a talk for #piday 2016, about different ways of calculating π: checkmyworking.com/misc/pi-day-20…

@EuclidAcademy "0 is not a number" went out of fashion in the Renaissance.

@SparksMaths @EuclidAcademy I think the sense @EuclidAcademy is going for is: if I say "there are a number of people in this room", negative numbers, 0 and 1 are all invalid quantities of people satisfying that statement.
That's just one context in which "number" is used, though

What does it mean when you've peer-reviewed tons of papers but only published one?
Is there such a thing as PhD-by-standing-in-community?
I've made a thing which draws diagrams to compute divisibility by N in any base, using @glitch.
divisibility-diagrams.glitch.me
@cameronesfahani @theoremoftheday start at 0. Dotted line leads back to 0. First digit 1, move 1 green arrow round to 1. Dotted line leads to 2. Next digit 2, move 2 green arrows round to 0. Dotted line leads to 0. Final digit 0, don't move.
You finished on 0, so 120 is divisible by 4
@cameronesfahani @theoremoftheday It's awkwardly worded to save space. I'll have another go
I think the rectangular pattern in that divisibility by 22 diagram should be much better known. Would you have expected it?
This is divisibility by 98 in base 66. That's an interesting shape!
@cameronesfahani @theoremoftheday I've changed the wording - any clearer now?
@willkirkby @glitch like, technically, or the maths?
@willkirkby @glitch you're interested in the remainder when dividing k by N. Start with remainder 0. For each digit in k, multiply your current remainder by 10 (i.e. shift all previous digits left 1 space), then add the digit. Work mod N. If you end up back at 0, you've got a multiple of N
@willkirkby @glitch Dotted blue lines from space i point to (10*i) mod N. Solid green lines point to (i+1) mod N
@willkirkby @glitch I've written this, but in more detail, at divisibility-diagrams.glitch.me/what.html
@Tony_Mann @mathsjem Yellow card: simulation. Play on.
The best part of the #bigmathoff is the top-notch game show host patter I use in emails that only the competitors see.

@CPANJGamble The vertices represent remainders. Like divisibility by 12 in base 10 has 12 vertices.

@OlympicsProf @colourblindorg Pedantry: I'd expect there to be a selection effect leading to that stat being lower. Could say that 1 player on every team *should* be colour blind

The second #bigmathoff semi-final is starting in 10 minutes. Meanwhile, we're at the halfway point in the @ch_nira v @ZoeLGriffiths match and it's close! This one could go either way
@mscroggs @ColinTheMathmo @ZoeLGriffiths there have been a few swapped leads, but most notable was @ch_nira overtaking @jamestanton late in round 1. Was fairly close before that, but James was mostly ahead.
@mscroggs @ColinTheMathmo @ZoeLGriffiths @ch_nira @jamestanton the @Gelada v @ColinTheMathmo round 1 match also turned round after about 6 hours, and never really looked back. (This one's a percentage chart because the gradient went crazy)
@ZoeLGriffiths @mscroggs @ColinTheMathmo @ch_nira @jamestanton I see the rumour that I'm a magic graph fairy is spreading. Kiddle v Chamberlain was close, but Nira was basically always in the lead
@AliDaliBee @MathsJam Assuming equal numbers of each colour, and enough sweets to ignore change in proportions, 6/125, or just over 4%. Three 1 in 5 picks, and 6 orders the colours can appear.

@ColinTheMathmo @ajk_44 @mscroggs @ch_nira @aperiodical I'm glad the #bigmathoff made this conversation happen.
(I won't be at MATRIX because it clashes with the tiniest L-P's birthday. Nira, come to big mathsjam!)
@peterrowlett @ajk_44 @ch_nira but Zoe's name has an odd number of letters, while all the others in the semis have an even number. If you care about diversity *at all*, you should vote Zoe.

A notational conventions question:
It's common to write "sin(x)" as "sin x", omitting the brackets. It's not just laziness: it makes the text less busy. "log log n" is easier to parse than "log(log(n))".

@sxpmaths I have protanopia (bad red cones), so basically no combination of colours works for me. I can use labelled pens, but they don't help me. All my schoolwork was in one colour. 1 in 12 boys are colourblind, so expect a couple in each class.

And in "absurdly precise numbers suspiciously close to 100,000 / 6" news... twitter.com/qikipedia/stat…
So, apart from my perennial gripes about @qikipedia's continuing citation-free problems with numeracy, this begs a question: what does a cheeseburger weigh six times as much as, or have six times as many calories as?
@Wolfram_Alpha says a cheeseburger weighs 200g or 7.1oz, which isn't six times anything, but it give 548 calories, which is close to 540 or 600. So a blue whale needs 9 or 10 million calories a day? Wikipedia says it's 1.5 million.
However, Wikipedia says a blue whale *sometimes* eats up to 3,600kg of krill in one day. 16667*200 is about 3,333kg, so we might be going by weight. But that's not every day!
Assuming krill have roughly the same caloric content as cheeseburgers (@Wolfram_Alpha doesn't know it), it looks like whales can eat 6 or 7 times their daily energy needs in one day. Wikipedia says they eat seasonally.
So that fact looks...
fishy.
😎
Actually, I'm not done with this yet: is 16,667 cheeseburgers more or less than I'd expect a blue whale to eat? Me to @itabn_andrew, which tells me 3,333kg is a bit more than an adult giraffe and a bit less than a shipping container. Or, excitingly, about 2500 human brains
And lots more comparisons besides: isthatabignumber.com/itabn/compare?…
It also tells me that 1 million calories is about 500 times a woman's recommended daily intake. So 10 million is enough for 5,000 women. That does seem like a lot!

That's really clever - this bottle of olive oil also has an expiry date for the prime minister. I wonder how they do that?
A few years ago, the BBC reported that Opeyemi Enoch had proved the Riemann hypothesis, and we (@aperiodical) immediately said "no, he hasn't" - aperiodical.com/2015/11/rieman…
Now, Sir Michael Atiyah claims he's proved it and we said "well, let's see".
Why the difference?
@aperiodical Enoch looked like any crank: went straight to the wrong venue - BBC News, not other mathematicians - didn't publish his proof in the open, and presented it at a very scammy looking conference run by Nina Ringo, who we've encountered before.
@aperiodical And we'd never heard of him. The false-positive rate for "anyone on the planet" with a claimed big proof is much, much higher than for, say, professors of maths in big universities.
@aperiodical So for all those reasons, we were fairly sure he hadn't done it, like I can fairly confidently say you're not holding a winning lottery ticket right now.
@aperiodical Atiyah, on the other hand, has a Fields medal, an Abel prize, and a very long list of publications. We still think he probably hasn't proved it, based on his other recent pronouncements, but he says he's going to present his proof, so we give him the benefit of the doubt.

I've just finished "Inventing the Mathematician" by Sara N. Hottinger. It's about how we construct the idea of who can be a mathematician. I didn't need convincing, so I was hoping for some good ideas to counter the straight-white-male norm, which I sadly didn't find!
There was lots of "in the following chapter/section I will show ..." and "in the previous chapter I showed ...", which felt like it actually made the gist of the book harder to follow. My wife the sociology graduate says this is quite common, and it used to annoy her too.
The majority of the book is about mathematical 'subjectivity' - for those like me who don't know the way that word's used here, it's not the opposite of 'objectivity', it means "what kind of person we think about when we think about maths"
It's made me more aware of all the situations in which we reinforce a fairly exclusive idea of math subjectivity:
* textbooks mainly feature famous male mathmos, fine, we already knew that
* exercises rarely feature female/BME characters (I'm on top of that in @NclNumbas: numbas-editor.readthedocs.io/en/latest/exte…)
@NclNumbas * textbooks specifically aimed at girls and women help to include them as math subjects, never mind "girlification" - I *think* I already agreed with that
* for women, there's a tension between being 'feminine' and being 'mathematical', which is unnecessary
@NclNumbas That's made me think more about the contexts we use in exercises and examples: 'neutral' contexts are often coded more as 'male' than I had appreciated. We should more often use explicitly 'female' contexts.
The last couple of chapters, about mathematicians on postage stamps, and ethnomathematics, didn't do much for me. I'm not sure what the point was - just saying "lots of people see stamps, so that's an important factor shaping their impression of mathmos" would've done.
And I really didn't get the bit about ethnomathematics. She talks about how it's rooted in anthropology and all its colonialist baggage (no surprise), and gives a good example of a more reflective and collaborative study, but doesn't really offer ideas for how it should be done
Like, how *should* we incorporate maths outside the standard Western narrative in the story of maths?

I'm looking in A-Level textbooks for examples of "simplification".
On the first page of content in this EdExcel C1 book, this made me so cross: you're not applying the rule (a^m)^n=a^(mn), you first need (ab)^n=a^n b^n, but that rule isn't even listed!
This is more what I was looking for: in the C3 book, they ask you to simplify "sin(θ)cos(θ)(sec(θ)+cosec(θ))". The answer they give is "sin(θ)+cos(θ)".
So do they mean "put it in terms of sin and cos"?
I suppose @sangwinc has written something about this. Must get his book out...

Could this be a thing: lottery arbitrage, exploiting the difference between expected return and maximum reward.
Someone who was going to spend £5/week on the lottery instead gives that to me. I don't buy lottery tickets, but occasionally they 'win' a prize, with expected value greater than the real lottery. I make sure I stay in profit. Win/win, right?
Alternately, I offer a bigger amount of money than the real lottery, just less likely. Caters to people who play the lottery for the possibility of winning big, not the expected return.
@aperfect yep
@aperfect I think the 'lying to the person who thinks they're buying tickets' part is novel, though
My dad have the tiny one a 'tablet' which is actually some kind of slate - pressure makes marks appear, and the 'bin' button clears it with some kind of electrostatic thing?

@DavidB52s @robeastaway and the follow-up probability puzzle, "one of David's answers is correct; what's the probability of picking the correct answer at random?" also submits to your method

I've just spotted this question in an Edexcel GCSE maths paper (1MA1/3H from June 2017).
If the table showed 'penis length' v 'number of men', what would your first thought be?
oh, and the range of lengths is between, let's say 5 and 7 inches
elsewhere in the paper:
* 'Daniel' bakes 420 cakes.
* We compare the amount spent on holiday by males and females, and decide if 'Chris' is correct to say "female students spend more money than the male students"
* 'Naoby' invests £6000
* 'Jeff' is choosing plants for his garden
* 'Jake' makes an incorrect assumption about measuring the length of a train track
Years after impishly proposing a 'unary division' operator at big #mathsjam, I find myself actually needing to introduce one in my real work.
Here's an untrue statement:
An even three-digit number is divisible by 6.
What's the best statement like this that *is* true?
@robeastaway No. Were you of the 'each bag has an equal chance of being' picked school, or 'each n-tuple has an equal chance'?
@DannyKodicek @ChrisMaslanka Just so.
@knightofmaths @ChrisMaslanka It's subjective, clearly. I'd interpret it as something like 'most satisfying'

I would like it if there was a 'member of' symbol which doesn't need to name the element in question.
That is, something like x ∈ ℝ but without the 'x'.
Something like '∈ℝ' would be confusing. Maybe above the set instead?
What symbols other than ∈ could I use?
@pippinsboss better because it's fewer digits?
@SaucySigma For things like:
(∈ℝ)^2 >= 0,
∈ℝ + ∈ℝ ∈ ℝ (hence why I want the symbol above the set's name, not to its left)
But the thing I'm thinking about at the moment is pattern matching, where I want to write something like x^(∈ℤ) or x^(∈ℚ) for integer or rational powers of x
@SaucySigma so basically statements of the form "f(x,y,z) where x,y,z ∈ ℝ" would be replaced with "f(∈ℝ,∈ℝ,∈ℝ)"

You can get a rough idea of if this is fair by modelling it:
Suppose Bercow picked order of questions at random. About 1 in 6 questions on the 26th were supportive. A geometric distribution gives the expected number of non-supportive questions before a supportive one (1/) twitter.com/MattChorley/st…
Probability of success, p = 1/6. The expected number of failures before a success is (1-p)/p = 5. So 31 questions before a supportive MP was called suggests that Bercow wasn't picking questions at random. (2/2)
Picking at random isn't a good way of doing things, as a speaker. I know next to nothing about parliamentary procedure, but I assume he'd use some judgement to pick questions so as to ensure the range of opinions is heard. There might be lots of competing non-supportive views

This feels like terrible communication of risk to me:
"Most adults living unhealthy lifestyle"
bbc.co.uk/news/health-46…
"The data from the Health Survey for England showed nearly nine in 10 had at least one unhealthy trait."
How unhealthy is unhealthy?
Smoking and drinking too much are some of the traits, as you'd expect, but so are "don't eat 5 fruit or veg a day" and "low rates of physical activity", which are in a completely different league of risk.
No link to more information, of course, because this is BBC News, and the "related internet links" seem to have been picked by a robot: a link to a random GP practice, the YMCA, and a community garden. No explanation of how those are relevant.
I've tracked down the summary of the HSE report; it's at files.digital.nhs.uk/5B/B1297D/HSE%…
As I expected, 71% of adults don't eat five portions of fruit and veg a day. Half of those have one or more other risk factors. Not convinced this categorisation is helpful
Oh, that's not necessarily true - 36% of people have only one risk factor, which I incorrectly assumed was always not enough fruit and veg.

Since the value the company is adding seems to consist of the automatic marking and LMS interoperability software, which isn't open, what have they added that allows them to put a different licence on the material?

I don't want to pooh-pooh that boy: he's quick at doing sums, which is a fun skill to have.
But the reporter picks big numbers with lots of zeros on the end. Tonnes of 10 year olds would be able to do the sums shown.
So the video demonstrates the reporter's poor number sense, and then who knows how many layers of editors who either didn't know or didn't care whether there was anything worthwhile in the report at all. Would they run a "boy finds rare animal" video showing a kid with a rabbit?
Or gobsmacked reaction shots as a child recites "she sells seashells by the seashore"?
The kid can probably do lots more (I hope so!)

@sxpmaths Coefficient of friction between the tyres and the ground isn't given, and you'd expect it to be much less than the friction on the skip, so can infer it's negligible. They should definitely have said that explicitly, though.
@sxpmaths it's like those geometry puzzles where an important length isn't given, so you can sometimes find an answer by inferring it's independent of the solution and setting it to 1
@sxpmaths @themathdiva but famously, wheels mitigate friction

.@My_Metro I'm having trouble with the smart bike lockers. I'm colourblind, so can't tell between red, green and amber lights. (cc @colourblindorg)
The info page says bikes at most 1720mm fit - which dimension is that? Surely all of width, height and length are constrained
@My_Metro @colourblindorg Just left Monkseaton. Chained my bike to the rack
@My_Metro @colourblindorg ... so, what are the maximum dimensions? It looked like my bike was too tall and the handlebars too wide, but 1720mm must be the length
@My_Metro @colourblindorg that doesn't contain any information about the maximum dimensions that will fit. If you can't answer the question, that's OK.
Now a moot point: it's been stolen. twitter.com/christianp/sta…

@icecolbeveridge @ajk_44 @RobJLow @reflectivemaths @Pecnut Less obliquely: there are some cool new tools that fairly easily take LaTeX and produce both printable PDFs and web pages.

@B_u_r_t_o_n yeah, another point against it. Stick www in front of it
@CounterOfSheep I wonder how I was supposed to hear about it in order to comply. I can't imagine it being upheld if ever challenged.
this has completely nerdsniped me. The statisticsviews article cites an article in SE London local paper "News Shopper" for the majority of its factoids. That article, of course, gives no references.
But we can do carbon-dating on the milk in swimming pools factoid! It says 2 pancakes per person, or 117 million pancakes. So the population of the UK was 117/2 = 58.5 million. That was around the turn of the Millennium (the population stat would be a year or two old when used)
Or, the author of the factoid had a really really out of date reference book. I can't find any hits for "117 million pancakes" before 2014, so that's probably the right explanation.
And lo, as surely as the sun rises in the east, I've found the source of the stat: an infographic released by Asda. visual.ly/community/info…
Actually, there are two figures at play: '117 million pancakes' is oddly precise, but '2 pancakes each' could be anything between 1.5 and 2.5!
Dividing 117 million by the population of the UK in 2014, 64 million, gives 1.8 each, which does indeed round to 2
So we're already 10% off. If you're filling swimming pools with milk, that could lead to an unfortunate spillage.
Now, swimming pools. An Olympic pool is about 2.5 million litres big, according to google. 93 swimming pools makes 232.5 million litres. That's more than a litre per pancake!
The recipe I use (Delia Smith's, obv.) asks for 200ml milk per batch, to make about a dozen pancakes. That's 1.95 million litres for the UK, or 78% of a single Olympic swimming pool.
So where did 93 Olympic swimming pools come from? It's a factor of about 100 off. Centimetres instead of metres on one dimension? Misinterpreted a percentage as a real number?
The figure for the amount of flour is easier to approximately check: 117 million is almost 10 times bigger than 13 million, so that'd be about 100g of flour per pancake.
I love pancakes more than anyone else I know, and I have never eaten a pancake that big.
If you're sharing this article with students as a source of fun real-world stats and your prompt isn't "do these stats make the slightest bit of sense?", please reconsider.

@SLSingh I'd be surprised if not - it's something we (at my uni at least) have been expecting for a few years, and experienced this year
@kyledevans @SLSingh It's what you said: the new maths GCSE
@SLSingh Mainly the new maths GCSE (and did that cohort do the new A level?), as far as I know. At Newcastle we weren't as badly hit as we feared, which our recruitment people take credit for
@SLSingh I half remember about there just being fewer 18 year olds this year, too. Engineering was very down on last year, again not unexpectedly
@paulscoombes @SLSingh I am not a recruitment officer, so I don't want to say anything authoritative. All I know for sure is we were expecting the drop

@robeastaway Hmm, I'm trying to articulate what's surprising about this. Is it that at each iteration sqrt(n) is a suffix of n?

The #PuzzleForToday is rubbish, for a variety of reasons. Yesterday's was particularly egregious - more a "guess what I'm thinking" riddle.
What would a positive version of the segment look like?
My starting point: 30 seconds of maths that you can think about for up to 10 minutes
Puzzles are fun, but unless you do lots of them, the vast majority of the time you'll bounce straight off them.
It's too easy, as seen in the Puzzle for Today, to dress up a fun maths fact as a puzzle, when just saying the fact would be just as satisfying.
However, puzzles give you a way of taking a family of problems that is completely understood in the abstract, and picking particular instances that still take some brainpower to solve. For example, I can write a general algorithm to solve sudokus, but I still enjoy them
If you just want to share a maths fact, it's very hard to boil it down to 30 seconds in a way that both gets the point across and motivates it
@blatherwick_sam Something like:
Suppose x=a^m and y=a^n.
Then xy=a^(m+n) .
And log xy = m+n = log x + log y.
Whether that's a "proof" in that it says something you didn't already know is debatable.

@ch_nira @aperiodical I had that thought just last night! This year, just keeping up with getting the pitches on the site has used up a lot of my time. I'll see if I can do something at some point.
@ch_nira @aperiodical I have a feeling I set up a JSON endpoint for @mscroggs's ceefax page. Fancy whipping up a graph, Matthew?
@mscroggs @ch_nira @aperiodical Almost definitely
@mscroggs @icecolbeveridge @stecks I'm enjoying the stickers though
@colinjcotter Yeah, but it feels a bit closer than what he's said before
@mscroggs @ch_nira @aperiodical Try this: aperiodical.com/wp-json/wp-pol…
@johndavidread @aperiodical Yeah, I think 24 hours is a bit too short. I only needed an extra day to allow 48 hours in the group stage, but that pushed the final into August, when I'm on holiday. The other option was more than one match starting per day, which I think is too much to keep up with
@johndavidread @aperiodical Yeah, that's what I meant - it entails another day before the result is known, which pushes the schedule into August
@matheknitician @johndavidread @aperiodical Exactly
@mscroggs @ch_nira @aperiodical @honeypisquared @3blue1brown and here it is a graph of percentages! I just got back to my desk and found my old Jupyter notebook.
#BigMathOff twitter.com/JimPropp/statu…
Here's a #math #3dprint I've just made.
What can you say about these pieces?
When I stack them on top of each other, this is what it looks like.
What do you notice?
@honeypisquared Farts-in-waiting
@benjamin_leis @honeypisquared Uhhh, you mean @SophieBays
@SophieBays @honeypisquared @benjamin_leis We've already got one competitor made of two people, so two competitors made of one person wouldn't be a huge upset
@kyledevans @aperiodical @becky_k_warren Every day! Time to take a hatchet to the polls plugin
@honeypisquared @SophieBays @benjamin_leis Does that mean... eeeeee!!!
Has anyone been following along with the #BigMathOff using a screenreader or other assistive tech? Was anything important inaccessible? Please say it was worth my while writing out all that alt text, I feel bad I haven't had time to check YouTube captions.
We're halfway through the group stage of the #BigMathOff! Whoop!
Why did I volunteer to do this much admin?
@JimPropp I think @alexcorner can teach you a thing or two about brevity
@metroapologises Have some ambition: faulty aircon might interfere with the wifi
@peterrowlett Crikey! Lends new meaning to the phrase 'railway sleeper'.
@panlepan There's a site called aperiodical.com that will publish anything you write about your favourite maths, any time of year. 😉
The math-off provides motivation, though, which is 90% of the battle
@becky_k_warren @panlepan would it help if I shared figures like number of readers, at the end?
They're quite good
I needed to get this out of my head @standupmaths
@ajk_44 @becky_k_warren @easternmaths ahh, is that what it is? I'll change it to a link
@ajk_44 @becky_k_warren @easternmaths I've updated the post so you have to press a button before the geogebra app loads. Please tell me if that fixes it
@ajk_44 @becky_k_warren @easternmaths you discovered my secret middle name, revealed only when my name is spoken backwards
As promised, I have taken a hatchet to the wordpress plugin powering the #BigMathOff polls. Hopefully they'll all behave from now on.
@peterrowlett Are you still on the train?
@honeypisquared @JimPropp If you haven't read Jim's blog, please do. He's one of my favourite writers about maths.
@umbernhard @standupmaths I originally had it that way round, but then I thought someone would point out that his hair was quite glossy
@SophieBays @aperiodical YouTube can do it automatically. I just need to go through and check the maths words

@icecolbeveridge Wait until I tell you about the absolutely brilliant tournament structure I've come up with for next year's #BigMathOff

Newcastle pals who work near the centre for life: is there a toddler friendly cafe nearby? (I'm not going in the fun bit, to head off the obvious answer)
I'm preparing the #BigMathOff posts for the week. You've got so many treats coming your way!
And the silly sports have all finished today. We're only halfway through!
@matheknitician @srcav @RealityMinus3 @icecolbeveridge @aperiodical @becky_k_warren @bluecombats I've just sent you 50 bonus stickers. Hope it's in there!

HOW DO YOU PASTE A BACKSLASH INTO THE NEW WORDPRESS EDITOR
@PaulsPrattle guess again! It strips them out, for reasons that I'm sure sounded good at the time
(you're also in for a treat tomorrow, and have had indistinguishably brilliant treats for the previous fortnight!)
@DrCaroSummers Of course a linguist would know all the alt codes! I can type a single backslash, but they get stripped out when I paste a block if text in.
In case you didn't see me at work today, it was a lot like this twitter.com/northumbriana/…

@kyledevans Now you mention it, a super over isn't a bad idea for the Extremely Fair Tiebreaker
Well, gang, I lasted half an hour doing real work before nerdsniping myself. Might have pretty pictures to share in a mo
So, @robeastaway tweeted, which made me think about zequals.
It's his brilliant time-saving device: when doing arithmetic, forget about all the digits after the first one.
For example, 123 z≈ 100.
You can look at the relative error of zequals compared to doing it precisely
If even the different kinds of digit are too much to keep in your head, you can also do zequals in binary. Here's what that looks like:
But I'm always looking for ways to do worse. So, what if you did zequals, but instead of keeping the most significant digit, you kept the least significant (non-zero) one? I'll call that 'meequals',
For example, 123 m= 300.
What does the relative error of that look like?
It looks like this! The error changes drastically from one number to the next, but you can still see the fractal-ish pattern. That's interesting!
But don't let the scaling on the plot fool you: this method is way, way worse than zequals.
@robeastaway Good point! Will modify my code after this graduation ceremony
@becky_k_warren @helenarney we had that! And a Europe one too

@HigherGeometer Elsevier is Dutch, so the GDPR should allow you to ask for your email address to be removed from their database

I've had a couple of student interns, Holly and Alex, working with me on #3dprinted #math for the last few weeks. They've done some brilliant work, which we'll be sharing. For now, I want to show you this kaleidocycle designed by Alex. It printed as one piece - that blew my mind!
The question I have at the moment is: what's the locus of the points on this thing?
@matheknitician Of course!
@soupie66 How weird! It's just a 3d printed thingy rotating. My hands are in shot, so maybe it thought it was a nudey show
@k_houston_math Yes!

@elinoroberts so he can't pretend in his first speech that he's going to be able to govern, I suppose
@icecolbeveridge I don't think that's quite it - the distances between the points aren't constant - but it makes a nice shape
@icecolbeveridge You must be right that the centres are always in the same plane. So does that mean that the hinges don't move in circles?
I feel like the author of this form and I disagree on some major aspects of ontology
@icecolbeveridge I did some fiddling to get it to work, and the middles don't seem to stay in the same plane. It confused me so I stopped!

I've just realised the train I've booked for #tmip2019 at the end of August leaves Newcastle at 05:58.

@robeastaway Lots of (most?) cafes, restaurants, and other places with taps in the centre of Newcastle have stickers up saying they'll fill your water bottle for you. A big public water fountain would be helpful too
I've had a coupe of days to think about @honeypisquared's #BigMathOff pitch, and I'm still not completely sure how I feel.
I'd like to hear your opinions! twitter.com/aperiodical/st…
@KarenCampe @aperiodical @samjshah2 but the whole thing's about working out why that pattern breaks, right? Anyway, if I'm going to change it I had esprit d'escalier this morning and realised "chord progressions" would've been way better
@KarenCampe @aperiodical @samjshah2 I've changed it to "an unexpected chord progression". Hooray compromise!

I've finally completed the #BigMathOff sticker book. I didn't have time to trawl through making swap requests, so I've just been accepting requests other people send me.
I've got 39 spare stickers left. If you're still playing, send me a swap request: mathoffstickerbook.com/friend/Md7OU4G…
While investigating this, I made this lovely plot, which I want on a t-shirt or a poster or something twitter.com/david_cobac/st…
@stecks I am currently moving at about 50mph away from the code that made it happen
@samjshah2 Is it true that any permutation of the columns (or rows) would produce another grid with the same property? In that case, I want to do something like sort the columns, and see if that looks nice.
@samjshah2 Want to hear my argument?
@samjshah2 Suppose swapping columns A and B introduces a bad rectangle.
Then at least one side of the rectangle must be in column A or B, say A w.l.o.g.
Then swapping the columns back puts that side of the rectangle in column B. But that's the initial arrangement, which had no rectangles
@samjshah2 I think you can express this as "the number of bad rectangles is invariant under permutations of the rows and columns"
@icecolbeveridge Don't make me write a rulebook
@icecolbeveridge I've just realised that every game of cricket ever has been played on the surface of a sphere, so one team could just stand on the other side of the boundary and declare the other team out of bounds

@icecolbeveridge @hartkp I'm not against it, but I'm not all for it either.
The Maclaurin series for e^x, in RPN, is:
1 x x 2 ^ 2 ! / x 3 ^ 3 ! / ... + + + ...
@honeypisquared @panlepan Welcome to the fraught world of gendered nouns in French
@icecolbeveridge @hartkp it could, but my point was about how awkward expressions with lots of terms look. I'm sure there's been some cognitive science done about this.
@icecolbeveridge @hartkp You also encounter problems when trying to write down the general formula: how do you write the differential operator? And then, how do you write the derivative of the composition of two functions? I think you end up needing a function application operation
@northumbriana we sold our house to him. Very nice man
@SheckyR man, I wish I was getting paid for this
@samjshah2 as a consolation prize, here's a 40x40 image of you that is also a prime number (I think)
@JulianMaths @mathsjem yes, it's really good. Properly hard though!
@samjshah2 @Gelada @zacharyabel ahhh, so sorry! I actually made the image data for the en-primed version, but that's the original. Hang on...
grep "simply" -r instructions_written_by_student
find instructions_written_by_student -type f -exec sed -i "s/ simply//g" {} \;
@samjshah2 @Gelada @zacharyabel Here you go. Not quite as nice this time. It seems to occasionally get lucky and find a prime without changing too much, and other times messes things up. I'm sure I could apply some simple divisibility tricks to the last few digits to make it quicker
@jjsanderson I had two students spend six weeks writing some instructions on 3d printing. They did some great stuff, but I now realise I should've kept a closer eye on their writing style
@samjshah2 @Gelada @zacharyabel ah! It found this one after only changing 104 pixels. That's pretty much ideal
@jjsanderson sub-editing doesn't currently feel like it'd be any quicker than just writing it myself. I know that's not true, though. They were really good!

95% of the work is typesetting the pitches in wordpress, and I couldn't work out a good way of sharing that even with Katie. I'd have to have much bigger lead times, which wouldn't be fair on the competitors. I'll do some thinking

@ShriramKMurthi Clearing is for students who didn't get the grades necessary for the unis they got offers from. In England and Wales, unis make offers before you've got your grades. When results come out, there's a mad dash to find a place
@ShriramKMurthi Unis below the top tier, i.e. not Oxford or Cambridge, try to get students who didn't apply to them but are at least as good as the students who did (and now, just try to bulk out their numbers with students they can just about justify taking)

They did lots of good work making mathematical things, and then I asked them to put together this guidebook in the last couple of weeks.

It could do with more care, but it's passable right now.
The #3dprinting #math material that my summer students Holly and Alex created is now online at mas.ncl.ac.uk/3dprintguide/
Finally, that site was created with the same system we use to turn LaTeX course notes into accessible web pages.
Not quite the right tool for the job, but it meant the tool got some much-needed improvements.
It'll be open source... at some point. Not mine to release!
One of the most important bits is the "things we've made" page - mas.ncl.ac.uk/3dprintguide/i… - with source files and thingiverse links for all the objects they produced.
@MouldS very nice Steve but my mug is round, I want a circled circle
Maths vocab question: when do two variables represent the 'same' value?
Let x be the number of biscuits in my left hand, and y the number of biscuits in my right hand.
If I have two biscuits in each hand, do x and y represent the same value, or are they still different 'things'?
@Helen31098957 not currently
@samholloway But x isn't identically equal to y, right?
@agbuckley @samholloway I very deliberately said two of the same kind of thing. I think there's still a difference between them to be preserved
@apgox Is that what that is?
I'll add some context: I was writing about algebraic simplification. I wanted to say that x and y represent different values, so they can't be collected together, e.g. 'x+y" can't be rewritten '2x'. But x and y might *coincidentally* have the same value.
So how do you describe the 'differentness' of x and y without talking about what they represent? They are different, but in what ways?
@elinoroberts Oh, now I do too

@OlafDoschke @stecks @k_houston_math Well, it doesn't do implicit multiplication, so what you really got was '4, 4' in the first case.

@OlafDoschke @stecks @k_houston_math Yeah, I wasn't sure if that'd be accessible to kids. I suppose it would
@OlafDoschke @stecks @k_houston_math It knows about prefix unary plus and minus
@OlafDoschke I need to write some text about how it works. I just wrote what you've seen on a train, and wanted to get it out. The idea is to think about what "order of operations" means. This is one interpretation

Oh no, I've deliberately obscured large portions of this ruler and I need to make sure these vegetables are whole numbers of inches long or my toddler will eat me instead: a #RealWorldMaths thread
As you might know, my daughter is both a very fussy eater and a superhero whose superpowers are an unbounded appetite and precisely eyeballing lengths.
Everything she eats needs to be a whole number of inches long (thanks for telling her about inches, grandad!)
When I stand up straight I'm exactly 6'5" tall.
I need to get these measurements exactly right, and I don't want to think about the alternative.
Only the 0, 1, 4 and 6 marks are visible. So I can definitely cut sticks that are 1, 4 and 6 inches long, like this:
But how can I measure 2, 3 or 5 inches?
Fun maths fact: 2 = 6 - 4. So to make sure something is 2 inches long, I just need to line it up with the 4 and 6 marks.
I can use some more Advanced Maths Theorems such as 3 = 4 - 1 and 5 = 6 - 1 to measure the two other lengths, like this:
Rulers with this property - as many distinct lengths as possible for a given number of marks - were investigated by a few people, including Simon Sidon, Wallace Babcock, Sophie Piccard and Solomon Golomb, in the 1930s.
Ready for the punchline?
Hooray, all the food is the right length and I will live to see another meal time!
But have you noticed that there are 4 × 3 ÷ 2 = 6 ways of picking two marks from 4? So this ruler gives me as many different lengths as it possibly can!
If you find that hard to believe, like I do, you can read a proof on Justin Colannino's page about Golomb rulers: cgm.cs.mcgill.ca/~athens/cs507/…
It's full of facts about all sorts of fruity variants on the setup, like circular rulers and modular rulers.
This is the best you can do!
There's no ruler with more than four whole-number marks that can measure every possible length up to the distance between the lowest and highest mark.
That's a lemma, a theorem, and a stone cold fact.
If you're relaxed about measuring *every* length and just want a ruler that measures more different lengths than any other, nobody knows a formula for making one!
At the moment, we know the best rulers for up to 27 marks. After that it's all conjecture.
And if you were keen to get involved with the burgeoning field of Ruler Maths but are sad that it's been entirely resolved, take heart: there's still something we don't know and that you can help with!
To take part in the OGR project (distributed.net/OGR) you just need to run a little program on your computer. It'll churn away, looking for rulers that do as well as they can, even though we already know they're not going to be perfect.
And isn't that all you can ask for?
So you can either sit down and do some hard thinking and come up with a formula, or you can join the distributed effort to check ever bigger rulers using computers.
(One of these is easier than the other)

@callmemeowskr If you don't like maths, you're not going to like the answer
@I8icecream @tweetsauce I wish!
@matheknitician I do now!
@tinysepticfan @tweetsauce Yes, but there are rulers with that many marks that can measure even more different lengths.
This is the idea: suppose that making marks in rulers is really, really expensive. What's the best value you can get by creatively using a limited number of marks?
@tinysepticfan @tweetsauce With more marks, you can make a ruler that measures lots of different lengths, but there'll always be some lengths you can measure in more than one way, so there's in a sense some wastage.

Ideas to use up the end of this spool of filament?
Art* is going on walls!
On the right is one of the Truchet pieces I shared above, and the other is made up of handwriting samples I gathered from colleagues. It feels good to finally put something out with this!
Here's a closeup of the handwriting one. I wandered round @NCLMathsStats knocking on doors, asking people to write some mathematical notation. It was fascinating seeing the different symbols and conventions used in different disciplines.
What can you spot in this snippet?
My idea was to have something that gives you an idea of notation used by mathematicians, but better than the 'cumulonumbers' nonsense you normally get.
There's just enough coherence to identify subdisciplines, but I didn't worry about keeping whole formulas intact
To make this, I took photos of all the handwriting samples, then used inkscape to convert them to vector images. I separated out individual characters, then wrote code to lay out characters along line segments making up a hexagonal tiling.
I wanted it to have a dark background so it would look like writing on a blackboard, but I was told I can't print a 99% black page at A0
Everyone loves talking about the subject they're interested in, and maths is a truly enormous subject!
Eventually, I want to put the original handwriting samples on the school website, along with links to the authors' homepages and short explanations of what they're about.
I learnt a lot about what my colleagues do just by asking them to write a line or two of maths!
Behold, the squircle-oid!

Another one. Here, flocks of arrowheads are tracing out the Herschel graph.
The Herschel graph is something I keep returning to, because our building is named after its inventor.
There's an easy proof of this: you can colour the vertices red and blue so that no vertices joined by an edge are the same colour, and there are an odd number of vertices.
So any lap visiting each vertex once has to end on a different colour to the start.
It's the smallest non-Hamiltonian polyhedral graph - you can't draw a path on it which visits each vertex exactly once, and it corresponds to a polyhedron.
There's no such thing as a "lap" of this graph which doesn't cross itself somewhere.
Here's an image showing the colouring property, by David Eppstein. If you start on blue, you have to finish on red, and vice versa.
How do you convey non-hamiltonianicity? I've got flocks of boids endlessly trying to trace out the graph. They're chasing (invisible) rabbits which are randomly walking the graph.

@DavidKButlerUoA @sxpmaths I like this puzzle. I feel like you should be able to get all algebraic numbers, but haven't worked out how yet
@DavidKButlerUoA if we're talking about the original problem where all the real numbers are dressed up, you can defo find all the rationals in finite time. It takes 2*max(m,n) moves to find m/n, when m and n are coprime.

ln is monotonic increasing on its domain, the positive numbers.
At x=1, we have ln(1)+ln(2) = ln(2).
So 0<x<1.
Do any of my @NCLMathsStats colleagues also grind their teeth when @My_Metro announces that "no trains will be running in both directions"?
@DavidKButlerUoA Yeah. And I think this is less clear than the ln(x)+ln(x+1) = ln(x*(x+1)) solution, because I got x=1 by inspection.
@NewcastleUniUCU and when I moved up to G recently, I was surprised to learn that didn't include the compulsory 20 minute lunch break, which they factored into my part-time calculation to reduce my pay even further.

@honeypisquared do you know of a decent taxonomy of mathematical topics, covering as wide a range as possible but particularly secondary and HE? At the moment I'm using the mathcentre taxonomy (mathcentre.ac.uk/types/communit…) which is old and missing lots of things
@honeypisquared I want a set of categories to describe what ideas a question assesses. The mathcentre taxonomy is a hierarchical thing with entries like "Numbers and Computation -> Arithmetic -> Operations -> Multiplication".
I don't think a hierarchy is correct, but (1/2)
@honeypisquared I want someone else to have thought about all the concepts involved in maths at the level I'm working in, and how they relate to each other, so I can have a standard way for question authors to say "this question is about factorising quadratics" without making up their own tags

Is this @My_Metro stat misleading? Does "escalators were working" mean:
- every escalator was working
- every station had a working escalator
- every station had working escalators in both directions
- they measured time each escalator was running, and took the mean
The first two options are straight out, because one of the escalators at Haymarket has been broken for weeks. And if it's the mean, should it be weighted by usage?
@Smylers2 That's the most pessimistic option, which I didn't even want to think about

V satisfying to shout when annoyed.
Mrs L-P has also banned "it should work" for similar reasons.
I'm not sure I've seen this puzzle before, and I really like it:
We have n keys and n boxes. Each key fits only one box. We shuffle the keys and put one in each box. Then we randomly break open 1≤k≤n boxes. What is the probability that we can unlock all the other boxes?
I'm trying to see if I can turn this into an intuition-challenging result, like the birthday paradox.
"100 boxes, I open 99 of them, prob you can open the last one?" (really high, not surprising)
"100 boxes, I open 1, prob you can open all the rest?" (higher than you'd think?)
The birthday paradox works as a demo because you can engineer an astonishingly high probability from what looks like a small part of the probability space.
Maybe this is the one probability puzzle that *does* match our intuitions.
@PetersenGraph that's certainly true!
@victorolosaurus @stevenstrogatz A key can be in the box that it unlocks. If you're worried about that happens practically, maybe a box snaps locked when you push its lid down.
I've been thinking about the fact that an n×n square grid has as many cells as a triangular lattice with n triangles on each side.
Is there a nice continuous bijection between them? When n is odd, you can at least keep one line of symmetry throughout.
Here's the same thing for a 2×2 grid. The triangle in the middle has to go one way or the other, so you have to break the vertical line of symmetry

I want as many different conventions for writing numbers as you can give me. I'm interested in contexts where there are different rules for how numbers are written, e.g. scientific notation, percentages, currencies.
I'm also interested in 'optional' things like grouping digits
Which numbers can you represent with different notations? For example, decimals represent numbers of the form a×10ᵇ, so not even all of ℚ!
What fruity sets can we find a corresponding notation for?
@semiBad that's a brilliantly lateral way of finding some! I've looked at the source code for a few internationalisation formatters though, so cut out the middleman
I've seen gas stations in the US show the tenths part with a fraction instead of a decimal.
Have you seen any other signage with a fixed denominator that isn't 10?
Or, more thrillingly, are there contexts where numbers are written as decimals, but some decimals are illegal?
This is sometimes true for currencies: a price like £1.054 would normally be rounded to the nearest penny. But if it's a price per unit, you might need that extra digit
@LearningMaths that's exactly what I'm looking for! Thanks!
@miclugo that rings a faint bell! Thanks!
@UD_engr88 thanks! Do you know roughly when it changed?
@DavidKButlerUoA @LearningMaths ahh, I knew I'd seen that kind of thing recently! Thanks
I've just seen that @mickaellaunay is doing daily fun maths livestreams: youtube.com/watch?v=J6tcnc…
Is anyone doing something similar in English?
@boss_maths @UD_engr88 yess, this is the kind of knowledge I need!
Percentages highlight an often-ignored point about rounding: if you've got a boundary, rounding to it can be very misleading.
For example, if something works 999 of 1000 times, it's not correct to say it's 100% effective. 99% is further from the true value, but shows the failure.
@jonpenguin oh, that's new to me. Thanks!
@oscarwlog Yes, that's a good vein of odd notation. Have you seen fractional numbers in hex or octal notation? I've definitely seen binary fractions, but can't think where I might have seen a fractional hex value
@CPANJGamble ... how did that help?
@poveryant As in 3,300? That's new to me, thanks
@EmJayLambert @icecolbeveridge That intrigued me greatly, but this page - metricviews.org.uk/2012/05/fire-h… - says the top number is the size of the mains, and the bottom is the distance to it, so it's just a scalar

@bbarber_ Could you do it online?
Slowly becoming more and more annoyed that the android and web-based versions of @msonenote don't have the "insert space" tool.

@dennisprangle Are you in the MSP online teaching group on Teams? We've been looking into that
@k_houston_math @_jcken @stecks It's very good for self-service formative use, and doesn't need anything installed to use. We're doing all sorts to support online teaching here, but early next week I should have a simple LTI solution which doesn't need installation but allows reporting score back to your VLE
@k_houston_math @_jcken @stecks VLEs with built in SCORM players such as Moodle and Blackboard (but BB is full of bugs) can also put scores from Numbas directly into their grade books without any software setup.
@k_houston_math @_jcken @stecks On the subject of exams: we're still thinking this through ourselves. Exams could happen in Numbas, but because everything has to be auto-marked, you're a bit limited in what you can ask. Randomisation reduces the efficiency of copying answers, though.
@k_houston_math @_jcken @stecks You can set questions creatively to test student understanding of concepts, but you can't ask for a proof. So, good for things like service courses and applied subjects, but less so for pure maths
@k_houston_math @_jcken @stecks One feature of Numbas' design will come in very handy: it runs entirely on the client, so not affected by poor Internet connections when submitting answers or rendering maths.
@k_houston_math @_jcken @stecks No problem, go ahead!
@poveryant So the games like NBA 2K3 conflict with that
@honeypisquared @asharpeducator And here's me with my own stupid name as a username!

@GhostMutt More tins of veg means either 2 or 3 veg.
Prob(3 veg) is easy, because there's only one way of doing it: 5/9 * 4/8 * 3/7.
Prob(2 veg) is a bit harder: either VVT, VTV, or TVV. So 3*(5/9 * 4/8 * 3/7)
Add those together to get total prob
@GhostMutt You could work out the probs for VVT, VTV, and TVV separately, but it works out the same (try proving that!)
PS: what system is that?
@GhostMutt A rule of thumb is: if you write more than a page of working for one calculation, consider looking for a one-liner
Liven up lock-down: it's not social distancing, it's Covid Ops.

A few years ago, we paid a web developer to make a website for us. The HTML uses single quotes for attributes, and is double-spaced throughout - there are two linebreaks after every line of code!
Just why.
@wordsandbuttons what's TFS?
@jjsanderson sed would fix it for me. It just boggles me that anyone would write code that way
@pimbellinga What do you do if a student can't explain their work? Write off the whole test?
@honeypisquared Very erudite.
Verudite.
@pimbellinga If you're only checking a sample of students, and one or some of them fail your check, you have to assume some unchecked students also cheated, so punish the whole class. I can't imagine students will think that's fair

Nice to have this tested in the real world: a student doing a @NclNumbas test lost internet connection halfway through the test. Fortunately, all data is duplicated in local storage, so later that evening they re-entered the test and all the data was saved back to the DB. Phew!

Finally got a quiet moment to record a #BigMathOff pitch.
Big fan of whatever this is that my face has decided to do

Now up to 7 #BigMathOff pitches. Nearly time to start!
An interesting example of Brouwer's fixed point theorem: I think the tummy button of the snowman on the girl's PJs lines up with her own tummy button.

@peterrowlett the two-year-old version of this is that things in the gardens have numbers, and we take turns shouting "run to 3!", "run to 1!" and so on. Recently she introduced number 7, which turned out to be "behind the little tikes car"
@peterrowlett I think so. I haven't pushed her to derive an incompleteness/inconsistency result

Do they not know that you can put links in emails? I get people putting screenshots in powerpoints, but this is a step beyond
Now imagining the cursed corporate email system that forbids links in emails "for security", but allows powerpoint attachments so anyone can get their work done.
@panlepan @ColinTheMathmo I also do this, and am also quickly shouted down
Simon Plouffe has found a sequence of 565 primes in 'geometric progression' (meaning they're the closest integers to the first 565 terms of a geometric sequence)

Where do UK people buy computer bits from when avoiding amazon? Specifically, I want a USB webcam. Options less heinous than Argos and Curry's, please. Back in the day it was dabs, but that seems not to exist any more

@matheknitician Yeah, I did but the framerate was quite low. I have a webcam on my laptop but I want something higher quality
I'm going to try making plaited bread. This will involve some group theory.
Follow along with me!
First, here's some dough that I've left to rise and just knocked back
I've divided it into 8 by cutting in half three times
Now I've rolled the bits into strands of equal length.
OK, similar length.
Next I have to connect them up like this, which reminds me of that puzzle about the hydra that I can never solve.
Your man Paul says: "Step 1: place 8 under 7 and over 1 Step 2: place 8 over 5 Step 3: place 2 under 3 and over 8 Step 4: place 1 over 4 Step 5: place 7 under 6 and over 1"
I need to label these tentacles
That looks like this. I think. I might not have done exactly the right thing, but I've definitely done some overs and unders.
To answer a comment: the numbers refer to positions, not tentacles, so you relabel after each step
So the immediate question is: where did each strand end up?
The steps are, in permutation notation (I say where each strand ends up) :
(2,3,4,5,6,7,8,1)
(1,2,3,4,6,7,8,5)
(1,8,2,3,4,5,6,7)
(2,3,4,1,5,6,7,8)
(2,3,4,5,6,7,1,8)
You can work out the final permutation by applying those in turn, to get:
(8,4,5,6,7,1,2,3)
So things don't end up where they started.
So... how many times do I have to do this to get them back where they started?
(brief intermission while some parenting happens)
One dance recital, one full potty and a cuddle later, I'm back!
This cycle includes every strand, so I don't get to do a fun bit of maths. I was hoping it'd be several disjoint cycles - cycles that don't share any strands.
This cycle is 8 elements long, so if I apply it 8 times I get back where I started.
You can write that permutation, (8,4, 5,6,7,1,2,3) as a cycle: now (a, b, c) means "a goes to b goes to c goes to a"
That is:
(1,8,3,5,7,2,4,6)
If the permutation *had been* a product of disjoint cycles, I could use a cool fact to work out how many times I need to apply it: the least common multiple of the lengths of all the cycles.
That's what I get for trying to apply maths in the real world...
Fans, I forgot to keep count. Let's say I did it a multiple of 8 times so everything's back where it started.

When we started planning to run @EAMSConf online this year, one of my main reasons was how hard it is for many to travel to the UK.
We've had more international registrations than normal, but still largely UK, EU and USA.
I want to do more to reach outside this bubble.
So, please spread the word: @EAMSConf is a free, entirely online conference about e-assessment in mathematical subjects, largely focusing on open source software. It starts 22nd June. More info at eams.ncl.ac.uk
@chalkdustmag @SparksMaths sorry, the version of me that has abundant spare time isn't on twitter
I keep seeing photos of 'packed' beaches and parks in the news. I'd like to see how that compares to the density of people in a terraced street. If the walls weren't there, what would it look like?
Problem: people signing up for a conference sometimes make typos in their email address.
Solution: bulk email the entire participant list, and wait for "message undelivered" responses.

The council cabinet has 10 members. "Balance" would be 5 men and 5 women (assuming a gender binary...)
What are the chances of exactly that happening in a meritocracy? Just under 25%. Far from odds on! (wolframalpha.com/input/?i=10+tr…)
Let's take Greg in good faith and suppose he wants a meritocracy, where gender isn't considered.
So each position has a 50% chance of being filled by a woman. (1/N)
twitter.com/nick_forbes/st…
Of course, there is widespread gender bias, in favour of men, so this cherry-picking is either ignorant or dishonest. It's certainly not evidence that there's a problem of too many women.
You can make just about any stat you like with a small enough sample.
The chance of having 7 or more women is just over 17%. (wolframalpha.com/input/?i=10+tr…)
So even if there was no gender bias, you'd expect 1 in 6 councils in the country to look this imbalanced (or 1 in 3 if you include imbalance the other way, with 7 or more men)

I'd like to share some thoughts from @EAMSConf, which ran a couple of weeks ago, to help anyone else running an online conference.
We were lucky that we'd decided to do everything online back in January, so all the hard thinking was done before lockdown started.
We decided to go online because of the subject of the conference (e-assessment) but also in order to include more people around the world who would find it hard or impossible to get to Newcastle for a physical conference.
Having decided to move online, we realised that the normal format of a couple of days packed with activities wasn't necessary or even desirable. Unlike travelling to another city, there's nothing stopping you just abandoning an online conference halfway through.
Travelling for a conference is a huge burden in time, energy and money, even when you don't need a visa. Personally, I'm restricted in what I can attend because Ehlers-Danlos syndrome leaves me shattered after a day of travel and standing talking.
So, we set a hard rule of two one-hour live sessions each day, at 9am and 4pm, spread across eight days instead of the normal two.
I think that worked really well, and the feedback from attendees agrees.
And, as most of us have discovered since, staring at a video call all day is knackering. There's also a timezone problem: there are only short times in the day when the UK working day overlaps with the Americas or the far east.
All questions were taken through the course website using a stackoverflow-like interface, rather than Zoom. This worked brilliantly. It let moderators carefully pick and reword questions, rather than the mess of unmuting people, and conversation could continue afterwards.
In the live sessions, we had a chair who introduced speakers and read out questions at the end, and someone else (always me) who played out pre-recorded videos via screen share. This worked better than expected! I forgot the sound a couple of times, but nothing terrible happened.
A lot of the talks were pre-recorded. I think maybe they should all have been. A couple of the non-recorded talks had technology problems, in spite of our efforts to rehearse beforehand.
We initially planned for more interactive sessions, such as workshops for the popular systems, but they made way for more talks. I think we should have made sure to keep them. There was very little of the sort of casual discussion you get at break times in a physical conference.
(We used the MoodleOverflow plugin: moodle.org/plugins/mod_mo…)
"Main", for conference info, general discussion, and reference. The general questions MoodleOverflow was used a bit, but the standard forum and wiki-style reference not at all.
There was an "introduce yourself" glossary which a few dozen people used, but nothing happened with it.
For non-Zoom activity, we set up a Moodle environment. It worked brilliantly, but some bits were used less than I hoped. We really wanted to give attendees an opportunity to see in action the systems we were talking about.
I set up four areas:
"Talks", with a link to the zoom meeting, recordings of all the sessions and individual talks, the question areas, and associated material such as slides. This worked very well.
"Play area", where everyone was enrolled with teacher privileges. I hoped that people would use this to try out the systems we had access to or show off things arising in discussion, but nobody touched it. We'll have to rethink how this should work next time.
"Software demos", with a course for each system being presented. There was a MoodleOverflow questions section for each system, which was well-used.
The stats show that only a couple dozen attendees clicked on anything in these sections.
I don't know how much people who didn't attend live sessions engaged with the non-live material. None of the recordings had more than 60 views at the end of the conference.
We were advised to expect about a quarter of people who signed up to actually attend live sessions.
We kept registration open throughout the conference. We had just over 300 registrations on the morning it started, and 420 by the end. Attendance in the live sessions was in the 80s early on, down to around 60 by the end.
Feedback from attendees: they really liked the stretched-out format, and the short sessions. Most made use of the recordings. Many missed the ad hoc discussion you get in person.
All the videos went on a YouTube channel (youtube.com/channel/UCMN_1…). Every video was initially unlisted, available only through the conference website. Now they're published and linked from the conference website: eams.ncl.ac.uk/programme/
In conclusion: A++ would do it this way again.

A helpful message added by IT to the bottom of an email thread in my inbox: "Warning: this message came outside from the university".
One problem: my university, or theirs?
I have a user interface problem that I hope isn't only solved by adding yet another option for authors to understand.
Student types a mathematical expression. We want to allow implicit multiplication, so `xy` is interpreted as `x*y`.
What to do about `pi`? Is it `p*i` or `π`?
My guess is that most of the time, you'd expect it to be interpreted as π. But it's completely reasonable that you might be doing something with complex numbers, and `p*i` is really what you meant.
I suppose rendering π would at least give you a hint to add the * symbol
@GhostMutt It doesn't replace what they type - there's a plain text input field, and a graphical rendering of the interpreted expression next to it. The interpreted expression is then marked.
@GhostMutt I do, but that's not something I want to do

For reference, @Desmos does implicit multiplication for most letter pairs, but replaces 'pi' with the symbol π. Pressing backspace just deletes the entire symbol. You have to type 'p*i' to get the product of p and i.
@Desmos @geogebra also does implicit multiplication most of the time, and 'pi' is interpreted as 3.14... but it isn't replaced with the symbol.
I've got a half-written @aperiodical post titled "The Enormous Difficulty of Telling the Truth with Statistics" that was mainly about @My_Metro escalators. The alevelgorithm might prompt me to finish it.
@marcuswu I think you're solving the parsing problem, which isn't as hard. What I'm concerned about is the practicality of students using this - they shouldn't be expected to understand how the parser works. They're often shown juxtaposed letters meaning multiplication, so they do it too

@NclNumbas This is a convenience feature that arose from writing this year's exams - quite often we had questions with several scenarios, each with multiple corresponding bits of data.
@NclNumbas The variable generation consisted of making lists of the values for each scenario, picking a list at random, then assigning each item from the chosen list to a different variable. This change makes it possible to do all of that in one go.

@ColinTheMathmo @icecolbeveridge without strings: max(n for n in range(100) if factorial(100)%(10**n)==0)
@icecolbeveridge @ColinTheMathmo is @ColinTheMathmo's point that the question is "how many zeros on the end?" and your code doesn't do that directly, it uses a theorem which avoids writing out the zeros
@icecolbeveridge @ColinTheMathmo I was getting at that from the other direction - computing for 100 in the most brute way I could think of

@jjsanderson the year of our lord two thousand and twelveteen
@DanielTruchet Ideally yes, but knowing the way "people services" works, they probably meant 1st October, leaving me 24 hours to use my 10 carried over days
@lukejanicke Fair enough
@mayhematics Opinion on that differs!
@alisonkiddle @peterrowlett My firstborn is currently stuck on "three months ago" as a way of referring to any moment in the past. If she wants to be more specific, "three months ago before bad germs" or "three months ago before the baby was here"

@Whitehughes Well, it's in the OEIS, but nobody has felt moved to write any interesting comments on it: oeis.org/A039703

@kyledevans That's weird, it's also my mother's maiden name!
Galaxy brain twitter.com/Oktahedro/stat…
@neil_calkin @Quelklef I do! Lovely sequence.
This was prompted by me thinking that there's a huge gulf between binary-ish sequences that only use 0 and 1 or 1 and 2, and others with much bigger range. I should have asked for sequences with between 3 and 5 distinct elements.
@neil_calkin @Quelklef Hmm.. The Wikipedia illustration for the Calkin-Wilf tree only uses the numbers 1 to 5 😉
@Kit_Yates_Maths "Call My Bluff Routine"
the first sequence in the OEIS with 5 distinct values in its a-file (but more in the whole sequence) is oeis.org/A000091. If you can work out what it's about, please enlighten me
The first sequence just using the numbers 1,2,3,4,5 in its a-file is oeis.org/A007001, which combines a nice entry number with a charming simplicity.

Monday morning. 62 unread emails in my inbox.
Why have I been having stress dreams?
It's "tell me not to use ambiguous notation" time!
Context: I have to interpret students' ambiguous notation.
I want to interpret `xy` as `x*y`.
Should `x/yz` be `(x/y)*z` or `x/(y*z)`?
Yes, it's ambiguous, but of the two options, which would be the least surprising?
@AndreasVohns @NclNumbas Bitte darf ich über diese Fragen im Numbas-blog schreiben?
@mathforge Both those cases match the behaviour I currently have, so I'm glad we agree
@SdixonSharon You can follow the order of operations for x/y+z. Do you think there's another way of interpreting it?
... now I have vague memories of seeing a comment along the lines of "juxtaposition binds more tightly than operator symbols" somewhere in someone else's code
@knightofmaths as typed on a keyboard, so the four characters x/yz
@robinhouston so how would you interpret it?
Really annoying follow-up:
Is `xy!` equivalent to `(x*y)!` or `x*(y!)` ?
@robinhouston The reason I'm thinking about this is that you might type something like `xy^2` to mean `x*y^2`.
I think in that case the juxtaposition doesn't bind more tightly - the exponentiation should happen first. Maybe juxtaposition is a way of breaking ties for ops with equal precedence?
@robinhouston I'll... inform my colleague who just wrote xy^2 that they're in the wrong timeline
@robinhouston yes, this is for my job writing e-assessment software.
@peterrowlett @icecolbeveridge Yeah, they get a live 2D rendering so *in theory* they can check it's been interpreted as they intended.
@Sally_Keely That's true if you apply the normal order of operations after inserting the missing multiplication symbol, but most people replying interpret x/yz as x/(y*z). I think the intuition is that juxtaposition is a bit stronger than using the * symbol
@virtualcourtney @Sally_Keely I think this is a prescriptivist/descriptivist argument.
Is now a good time to link to the thing I made that lets you make up your own order of operations? checkmyworking.com/misc/samdob/
@virtualcourtney @Sally_Keely well, people wrote prescriptive rules saying you shouldn't split an infinitive or end a sentence with a preposition, but that's something up with which many people will not put
@bwebste @pkrautz Does this work when you replace letters with numbers, or are there different rules?
How do you feel about:
x/2z
3/4z
1/yz
@virtualcourtney @Sally_Keely I suppose I'm willing to go with "the rules are wrong", based on how people use this notation in practice
I'm getting some very authoritative answers in both directions to this. twitter.com/christianp/sta…
@bwebste @pkrautz so 3/4z is 3/(4*z)?
@virtualcourtney @Sally_Keely I have yet to encounter a situation where adding parentheses made things worse

I've got a new sequence in the OEIS. It's to do with a really simple number game I made up. Here's a video explaining the rules
youtube.com/watch?v=ZtGcd0…
Which starting numbers eventually get to 1? In the video, it looks like starting at 4 doesn't, but starting at 2 does.
My new sequence, oeis.org/A338807, lists the numbers that eventually reach 1. I'd love to know if there's a pattern!
Think of a number, and keep a running total starting at 0. Each turn, add your number on to the total. Then, if the old total was a multiple of your number, add one to your number. Otherwise, subtract 1.
The game ends when your number is 1.
You could think of this game as "the Collatz sequence with a running total" - what happens next doesn't just depend on which number you're on now, it also depends on all the numbers you've seen before.
(my enemies might like to look at the editing history of the OEIS entry to see what a mare I had trying to compute it correctly and then format it properly)
@BEBischof nope
What's not in an encyclopedia?
Wikipedia: all the right facts, not necessarily in the right order
@BEBischof yeah, I think so: call your number at step i N_i, and the total T_i. Consider the set of triples (N_i, N_j, T_i mod N_j) for all j<=i. If at some step all those triples are ones you've seen before, nothing new is going to happen so you'll never reach N = 1

Can someone save my sanity: I can't believe this isn't in the OEIS, I must have made a mistake.
"a(n) = the first column of Pascal's triangle in which n does not appear".
Labelling the first column 0 and starting at n=2, I get

There's making a rounding error, and then there's rounding off to two decimal places after each step of the calculation. And a PhD student did this!
@KarenCampe this situation involved exponentials. I'm quite concerned!
@eqdynamics I've already got that set to true, and it still happens
Is there a gpiozero-style Python package for sending gcode over a serial connection? I can find a lot of hacked-together scripts, but no nice reusable package so far.

@robinhouston I voted "finite state machine" but my actual first thought was "is this one of those weird kink acronyms I have to be careful not to google?"

For _reasons_, I want to know what the densest British coin is. I'm astonished that google doesn't already have the answer, but it does have this table.
Finally, a reason to use a spreadsheet!
So for reference, the 20p is the densest coin, with pretty much everything except 1p and 2p tied for second place.
@bbarber_ no, but my first guess is that the metal mix of the 50p is more hard-wearing, but too expensive for the 20p
@lukejanicke I got an EleksDraw, a v v shonky alternative to the AxiDraw, but about 25% of the price.

@standupmaths Did you do what I did, and on reading 'once every 200 years', scroll through your calendar app to find the previous and next years?
@standupmaths because there's no way that factoid was worth doing the quick maths to work the dates out without looking at a calendar
@desdotdev @standupmaths the leap year rule is more complicated: year N is a leap year if N is divisible by 400, or by 4 but not 100.
@peterrowlett at that point, you need to ask what's the compressive strength of a numberblock?
@peterrowlett On a related note, I thought recently about how @numberblocks could talk about infinity not being a number. If you had an infinitely big numberblock, you could maybe say where its feet are or where the symbol on top are, but not both at the same time. So not a numberblock, QED

@der_flow_ I bought an EleksDraw recently. I've got it working, but it's taken loads of work and the build quality isn't great.
@artandtech @der_flow_ Eleksdraw, not eleksmaker. Main problem is that the rail for the pen holder was incredibly stiff, even after lubrication. I've stuck some weight on it to overcome friction, but that means it tips a bit when fully extended.
The screw thread on some of the plastic died quickly, too
@artandtech @der_flow_ It didn't come with a socket adaptor for the power supply, just the generic part, so I had to buy one. The assembly instructions are absolutely awful. Eventually found a YouTube video describing how the delivered kit differs from the one in the instructions

The names in this question were chosen by @NclNumbas at random, based on ONS data.

@DavidKButlerUoA Nice! Though I think I'd measure that in giganewtons per hectare, unless it was a very shallow lake
A herd of cows coming in for milking.
A cow weighs about a tonne, or 1000kg, so a herd of 100 cows would apply a force of about 1 meganewton to the ground. When they're coming in for milking , I reckon they could all fit in a 100m×100m area, or a hectare.

I've been thinking about the best way to present a mathematical thought in a tweet. When I tweet a prompt or question, it's often hard for you to determine:
* do I have an answer in mind?
* do I believe there's a correct answer?
* is this a serious question?
...
* how much thought have I done about this so far?
* how much do I care about the answer?
For example, this recent question: twitter.com/christianp/sta…
The answer I had in mind was "no", if philosopher-kings are playing, but I was interested in whether you could ignore that and have a go at playing anyway.

I'm not sure if I should add something to this kind of tweet to let you know where I'm coming from.
I like how @jamestanton often tweets thought-provoking questions, and it's rarely clear if James knows the answer, or if there even is an answer. Sometimes it's a well-known theorem, other times something that just occurred to him.

It's extremely on brand that the mathematical postcards I sent have all had "World Autism Week" printed on them in the postmark
@Cshearer41 Glad you like it! I sort of ran out of time to make it non-shoddy.
Anyway, I looked in Mathographics for ways of drawing eggs, and didn't find anything easy. I've just picked it up again and noticed the cover
@Cshearer41 It claims it's fancy, but the batteries gaffer taped to the pen holder as counterweights undermine that somewhat
@LoveInner @Cshearer41 that is just the equation of an ellipse: you've got pi/4 instead of x/4 in the exponential, so it's constant.
I also realised after putting the card in the postbox that it should be 5/4
@ilarrosac @Cshearer41 Yes, I realised I had it the wrong way round after I'd posted the card!

Hello, @glitch! My 3-year-old wants to know if your fish have names
@BernhardWerner @JavieRonquillo yeah, I get that
@peterrowlett good point about the aspect ratio. I've changed it to make it 16:9. We'll see if this is any better.
I have the same problem with the link in firefox on my desktop, but not on my phone.
@glitch She suggests Martha and Dee
@standupmaths Did you see the artisanal integers sites, back in the day?
@DanielColquitt Well done! I dug a much smaller border than that last year and I decided to quit gardening afterwards
@nhoskee @BernhardWerner @JavieRonquillo Now it's pointed out, I get that, but I'd have to delete the original tweet
My first tweet about this contained an example using pictures of humans. A couple of people rightly pointed out that that could lead to some unwanted reactions to the prompt, which I hadn't realised. I've deleted it, so here's another attempt
I've made a tool for making "Which One Doesn't Belong?" pictures.
You can put text or pictures in each square, and change the colours of the background and text.

It's a good thing the universe is eventually going to fizzle into nothingness, because otherwise someone would be born in a year that would take more than their entire lifetime to write down on the birth certificate, and that's no way to live
@icecolbeveridge @madebyburton @WhiteRoseMaths @rekenrek101 @aperiodical Can't remember if it's in the post, but once I bought the domain hotmathematicians.com so I could have the email address christian@hotmathematicians.com, and similar for anyone else who wanted one.

@bethanyaus @hvhuizen62 @ionicasmeets You read from bottom to top. It baffled me for a while too
@bethanyaus @hvhuizen62 @ionicasmeets Although it looks like the i and j diagrams are the wrong way round. Oops!
@jonathanavt @ionicasmeets The i and j diagrams are accidentally swapped, and you read from bottom to top. Does that help?
@TedG @aperiodical A few minutes
@Kit_Yates_Maths At least you didn't make the other classic mistake and microwave some metal
@DrEugeniaCheng Same! My wife took our daughter into hospital yesterday for minor surgery, so I started packing her lots of tasty snacks. She said "I won't be able to eat, I'll be too worried."
We're similar in lots of ways, but that just didn't compute for me.

Do some big companies buy blocks of mobile numbers for company-provided phones?
@kyledevans I was halfway through factorising 810 before I realised I'd misread the first one
@soupie66 @MathematicsUCL yeah, there are a few more in Unicode, at least:
ↁ = 5,000
ↂ = 10,000
ↇ = 50,000
ↈ = 100,000
Whether those are the same as D and M is maybe up for debate
@peterrowlett plot twist: the bookmark is a USB key containing thousands of digital books
Here's a thing: while writing a document about decolonising our curriculum, Word's "Editor" feature popped up. It gave me a low spelling score because of...
all the foreign names it didn't know!
What a great example to include.
Dear Word,
"In formal writing, try spelling out the words" is unwanted advice. I rarely write formally.

I remember seeing a map of the world (or just Europe?) showing the standard form of the equation of a straight line in different countries.
I can't think what to put into google to find it again. Can anyone help me?
@ch_nira is there a canonical version of your "Black Heroes of Mathematics" talk online anywhere? Or if not, where's the most recent recording?
@BernhardWerner not the one I can remember seeing, but I wouldn't be surprised if one is a knock-off of the other.
Which formula did you learn?
@BernhardWerner thank you for that link, by the way. How did you find it?
@El_Timbre that's great, thanks!
@El_Timbre You might know this: has (y-y1) = m(x-x1) replaced y=mx+c in the national curriculum? If so, when did that happen?
@El_Timbre Ah, so our maths undergrads would have learned the other form in maths a level, but someone with just GCSE would only have y=mx+c?
I'm surprised! The coordinate form seems much more useful
@ch_nira Thanks! That's what I thought was the most recent one

@stem_wales already in progress, thank you
@ZoeLGriffiths When I'm in charge the green bottles fall off in Zeckendorf numbers.
The three-year-old is completely uninterested in maths and can't count past 15, so it's a solitary pursuit
@stem_wales yeah, I saw that, and wasn't surprised to see Nim turn up given the rule behind my sequence, but it diverges quite early
@nicole_cozens I agree!

π can stand for a variety of things in maths, but is 3.14159... the only constant it's conventionally used for?
and the same question, but for e
@ben_nuttall My first go at that tweet asked "is that all it can be used for", but I stared at it for a while before changing to "is conventionally used for", and your reply is why
@GoranNewsum yes, that's something I'm also interested in at the moment: different names for the same thing
@ben_nuttall For constants?
@njj4 none of those are constants though, right? In the sense that if we're both doing topology, my π might not be the same projection map as your π
@Mat_Hunt thanks!
I'm also interested in any non-number constants with conventional names that you're aware of. At the moment I've only got ∅, for the empty set, and e for the identity permutation
ooh! i, j and k basis vectors!
@ZenoRogue it does for my purposes, and is in fact the example that prompted this train of thought
@virtualcourtney that stretches my understanding of what a constant is, but it's in the same sort of area, isn't it?
@mattmcirvin thanks for these! I guessed that physics would have a lot of constants, but I wasn't aware of any non-number ones. I'll go and look those up
@mattmcirvin I'd be more inclined to call the Kronecker delta a function
@sarahlovesmaths yeah, I'll take the named number sets.
I is tricky: you need a bit of context to say what dimension it lives in, unless you define matrix multiplication more expansively than the usual textbook definition
@sarahlovesmaths and I wonder if there's a list somewhere of all the different conventions for the standard basis vectors
@sarahlovesmaths how have I not watched that yet!
Complete graphs! K₅ etc
@odedude but those are both variables, right?
@alisonkiddle @edsouthall This morning my daughter asked me "why have you got so old?" as if it was a conscious tactic on my part
@ben_nuttall yes, I've always had to go to the website. I think the app says somewhere it only takes PCR tests
Time for another round of "when is it OK to omit the multiplication symbol?"
I think for powers of numbers, it's fine to omit, e.g.
2²3² = 36.
What about subscripts, for the number base, e.g.
12₅23₅ = 331₅,
or do I need a multiplication symbol:
12₅ × 23₅ = 331₅.
Or, less esoterically, when I've got a subscripted variable followed by a number, e.g.
x₂4
(I will not accept "put the 4 first" as an answer)
@jjaron I think one reason this is worth noting is that it's easier for one huge company to take action to reduce plastic use than for thousands of small companies to coordinate

On those occasions I high-five the wall.

Today in dysautonomia: had to abort my shower because I couldn't stand up long enough
@MarcusduSautoy but marcus they're so annoying
I tweet things like this because the ways in which I'm disabled are all pretty much invisible, and I think it's important to know that healthy-looking people live with these sorts of problems.
I usually include a medical name for the condition I think is most relevant because otherwise "I couldn't stand up long enough" might be interpreted as "I had a big sesh last night" or something else that I could mitigate.
But it's tricky, because I've been diagnosed with like a dozen things that overlap with each other in many ways, and nobody seems to understand what they really are, or what causes them.
So today is it dysautonomia, or dyspraxia, or Ehlers-Danlos?
I'm fairly sure it wasn't colourblindness, at least!
I don't really like having this long list of really rare things - it looks implausible. But they all overlap, so P(dysautonomia | dyspraxia) is pretty big, I think
@icecolbeveridge Thanks! Glad it's not just me
@icecolbeveridge ooh, the game is coming up to 3 million attempts!
Update: I mowed the lawn. My autonomic system is a land of contrasts 🤷

As part of running @NclNumbas at Newcastle, we get copies of students' accommodations, as agreed with the disability office.

@NclNumbas I don't think we have a bad disability office. But I do think we could be doing more to establish what would particularly help students for each assessment method.
I've just merged branches from the past year's development work on @NclNumbas together.
Incredilbly, all the tests pass!
Going for a victory lap, Jonathan Edwards style
@DeathCab4Callie My experience as a disabled student was that most lecturers were happy to go along with what the disability office said, but a couple insisted it would compromise their teaching style. In effect this excluded me from their courses.
@DeathCab4Callie As a staff member, I advocate for students when I know what they need, but the information we get from the disability office is so minimal and written only with standard assessment methods in mind.

I've made a game where you're shown a random unicode character and have to guess its name.
unicode-guessing-game.glitch.me
I used @elmlang on @glitch.
@cs_kaplan @elmlang @glitch I don't think so. There isn't a direct method, and I'm wary of doing something like trying to display it and measure against something I know will be displayed as a box.
Weirdly, my android phone which should use Google's Noto font displays far fewer characters than my Ubuntu PC
@cs_kaplan @elmlang @glitch So I suppose its a team game, with you and your browser against the Unicode consortium
@cs_kaplan @elmlang @glitch Well, I reckon the GNU unifont (unifoundry.com/unifont/index.…) would do it, but I like seeing what characters I'm missing
@CardColm Aahhhh that's just reminded me I forgot to marinade my pork for tonight!
@JanvierUK so how did it go?
@d_yellowlees I saw this and I thought of you: whatismote.com
Have you seen it before?
@cs_kaplan @benjymous @elmlang @glitch The fact that they display on my PC suggests that I can put together a webfont to make them work for everyone.
But is this how I should use my time? 🤔

@standupmaths You're wrong, Matt, but the word that is tha maximum amount of fun to type is currently my password, so I won't be telling you what it is
Here's a question: is it OK to omit parentheses around the argument to a non-standard function?
Like, "sin x = sin(x)" and "log z = log(z)" are common, but what about "f x = f(x)"?
Does the function name need to be more than one letter?
"flop x = flop(x)"
@BernhardWerner what do you mean by linear? I wouldn't say sin and log are linear.
@BernhardWerner Aha!
@pwr2dppl I can forward you some heated arguments for both sides of this question that I've received, if you want to lose the will to ever think about it again
@GoranNewsum Interesting! Can you remember which subjects?
@dginev That's excellent work, thanks!
@dginev How did you find these? Looking through a few of them, I haven't found one yet where f is a function, and "f x" can only mean "the application of the function f to x".
@dginev Ooh, that one looks good, thanks
Why is there no mathematical italic small h in unicode? The rest of the alphabet is there! This is madness
@FakeUnicode what's the deal? There's a bold italic small h, and even a bold sans-serif italic small h, but no plain old italic small h!
There's a free codepoint for it between g and i, so WHAT'S THE UNICODE CONSORTIUM TRYING TO HIDE?
@jontix no, that's specifically sans-serif. There are implicitly serif 𝑔 and 𝑖 at U+1D454 and U+1D456, respectively
@robinhouston I spotted that, but it doesn't look the same as the other mathematical italics in my default font. So maybe that's a problem with my font.
@robinhouston I'm sure the unicode people have had this argument millions of times, but this feels to me like the problem with having a mix of characters named for their meaning and characters named for their appearance
@robinhouston Yeah. I expect a screen reader would read out "planck constant" though, which is no good if I mean something else
@benorlin I like it. Nobody notices how quiet it is in the newsroom whenever there's an emergency
@robinhouston you're right: "Arimo" has ℎ but it uses "Latin Modern Math" for the rest of them, and forcing Latin Modern Math gets a matching ℎ

Is there a name for units of measurement that you can't reasonably add or subtract?
Examples: temperatures in Celsius; UK shoe sizes (a size 9 shoe is not as long as a size 4 and a size 5 shoe laid end to end)
@BlindMath Hmmm, I think that might be too strong - without context, is interpret that as meaning two measurements can't be compared
@joshbfitzgerald Shoe sizes are linear - the length of a shoe is (12 inches - size×barleycorns)
@sarahlovesmaths Good suggestion! I can't prove it but I just had exactly the same thought while putting the baby to bed
@BlindMath @joshbfitzgerald Ah! I guessed that there's a different definition of 'nonlinear' to my fuzzy understanding
@johnharvey_math I wasn't sure about what degrees Kelvin represent. Does something at 200K have as much energy as two things at 100K?
@johnharvey_math Yes, that sounds right to me. Always worth hedging your bets on twitter though!
@johnharvey_math Oh, but maybe something at 200K gives off as much energy as two 100K things next to each other? Is that how temperature is defined?
@johnharvey_math @langtoneagle Shoe sizes also have both of these properties
@shin_dmitry Nice, thanks!

Is there a name for the way you order titles of things like books, where you ignore words like "The" at the start?
e.g. "Anteater, The; Bees Are Great" instead of "Bees Are Great; The Anteater".
It's weird being asked to make a certificate of participation for someone who gave a talk at a conference.
Like, their employer won't accept seeing a recording of them giving the talk on the conference website, but will accept a PDF I knocked up in a few minutes?
Bureaucracy!
A strong part of me wanted to make something really snotty, to show my objection, but this is someone's job so instead I have to work out how fancy it needs to look in order to appease whoever has to approve it
@njj4 indeed. Someone last year asked for the certificate to be stamped and signed by university officials.
I was like, 1) I wouldn't know where to begin with that, even if 2) there's a pandemic on and I haven't physically seen a colleague in months
@ascii_only thanks! From that page, it doesn't seem there's a specific name for the convention of ignoring common words from the start

@Tom_Ruen @panlepan @akivaw @standupmaths or, a colourblind person's perspective: don't use colours at all
Looking at Canvas's (old) quiz engine.
For a numerical question, you can set an "answer with precision": you give a decimal answer, and an integer precision.
It looks like "precision" means "significant figures", since 12.345 gets rounded down to 12.34.
But...
The marking is also confusing. "12.34" is marked correct, as I expected, but so is "12.340", which doesn't represent the same precision.
While the QTI export's marking condition just says 12.335 < answer <= 12.345, that's not how Canvas marks it: "12.33888" is marked incorrect.
Nobody told the person who made the front-end, because when I write 12.345 in the box it's immediately replaced by 12.3400, implying "precision" means "decimal places".
This stuff isn't simple: @NclNumbas has a tonne of options for how to mark a single number (docs.numbas.org.uk/en/latest/ques…)
It feels like Canvas makes every mistake it can, resulting in contradicting at least one assumption anyone might make

At the moment we use the mathcentre taxonomy, which has big gaps and is weirdly specific in other places.
@honeypisquared @Samuel_Hansen @NclNumbas Questions I want to answer:
* Hierarchical, or something more complex?
* Just objects, e.g. 'quadratic equations', or just tasks, e.g. 'factorise a quadratic', or a mix of both? (mathcentre is a mix, but heavily objects)
* How to relate to standards such as GCSE and Common Core
@honeypisquared @Samuel_Hansen @NclNumbas @CambridgeMaths can I see that?
@honeypisquared @Samuel_Hansen @NclNumbas @CambridgeMaths but you're focused on primary and secondary, right?
@honeypisquared @Samuel_Hansen @NclNumbas @CambridgeMaths are you free either today before 3pm, or Wednesday or Thursday morning?
@Samuel_Hansen @honeypisquared @NclNumbas @CambridgeMaths thanks!

@honeypisquared at #TMiP2019 @ZoeLGriffiths had the idea for a show where you talk about maths in the kitchen, so I suppose I can offer talking about maths in the... loft?
I remember in 2010, thinking "how will I put up with five years of this lot?"
Happier times.
@pwr2dppl Unless it came from the Équation region of France, it's just a sparkling relation.
@pwr2dppl Seriously, my gut feeling is that for many people's definitions of 'equation', whether this is one depends on where x and y came from
A notation question: how often do you use square brackets for grouping, with exactly the same meaning as parentheses?
Do you use them differently in handwritten vs typeset notation?
@icecolbeveridge because it's hard to reliably draw parentheses of different sizes?
@wspr That would certainly get round the problem of "is this function application or implicit multiplication?" (whystartat.xyz/wiki/Juxtaposi…) but it's the opposite of what Mathematica does. I'd go with your way round if I had to choose, though
There's lots of mockery of this error (possibly made in bad faith) but I can see how, knowing nothing, you could interpret it to mean "47% of adults are less likely".
The way English handles percentages isn't exactly rigorous. twitter.com/soapachu/statu…
@icecolbeveridge Absolutely
@icecolbeveridge "the dude from Right Said Fred is overconfident" isn't exactly news, like
@RichardElwes It's hard to know where the balance is. Everyone's suddenly aware of the downsides of open-book assessment, but timed, invigilated exams also have well-documented problems with fairness and reliability.
@RichardElwes OK, I had "at-home, open-book" but removed "at-home". I suppose the statement is good in that it doesn't knee-jerk say that at-home assessment shouldn't happen at all, which I've seen some institutions say.
@DavidKButlerUoA Is your point that people don't engage with your feelings about it, or that saying "that's easy" and referring to something you haven't heard of makes you feel worse?
@DavidKButlerUoA Thanks! I saw a lot of people responding to the funny words, and wanted some discussion of your actual point.

@peterrowlett @Samuel_Hansen @honeypisquared @NclNumbas @CambridgeMaths Can't you remember the trouble I caused last time I wrote a paper for Connections?
@MiniGirlGeek I was in a similar position when I graduated (I'm autistic and dyspraxic, are my main employability issues)
I got a job in my uni's maths support centre, by asking if there was any hourly work in the department I could do. I was lucky to be able to take my time finding something
@MiniGirlGeek I've always been up front with my disabilities and asking for accommodations, but I've only ever worked at this university, which is good about that sort of thing
@peterrowlett @Samuel_Hansen @honeypisquared @NclNumbas @CambridgeMaths I was very unhappy about having to make a word document. Maybe I kept that go myself!

Some more playing with @CuttleXYZ. I've written a modifier to weave two paths together.
I think I'm in the categorical dual of a zoom meeting: someone just said "this is not so much a comment as a question"!!
A notation question:
The polar form of a complex number is r⋅exp(i⋅θ).
Which, if any, of these are in polar form?
A) 5⋅exp(2i)
B) 2⋅exp(i⋅π)
C) (4+√2)⋅exp(i)
D) exp((4+√2)⋅i)
E) exp(0i)
F) exp(0)
G) 1
@RichardElwes Even G?
@htfb @RichardElwes the \cdots are just to give a little bit of space, really! Mathematical notation in plain text is hard
@htfb @RichardElwes would you really distinguish between E and F?
@htfb @RichardElwes interesting - so you distinguish between the real zero and the imaginary zero?
@sangwinc ah yes, I meant to!
@RichardElwes I suppose my perspective is that the point of saying something is in 'polar form' is that you can read off the magnitude and argument.
'1' is equivalent by algebraic shuffling to '1⋅exp(0i)', but you have to know some facts about 1 to know what the argument is.
@tausbn @CuttleXYZ Yeah, I spotted that but decided I'd keep quiet about it!
@dginev even G?
@gregeganSF LA and Houston are pretty spread out. Looking at google maps, I can get distances between 2160km and 2278km by picking different points on the city limits. So Mathematica is still probably wrong, but maybe not as wrong as you'd think
@gregeganSF is that calculation in one of your screenshots?
@jjaron You need to start the supply chains newsletter. If not you, who?
@peterrowlett that desk is giving me palpitations!
@dginev yes, I think that the relation between notation and quantities with types is something that most mathematicians don't really think about, but becomes a big problem when computers get involved
@dginev in this instance, I'm specifically interested in the notation

In my continuing quest to boil the concept of a 'game' down to its minimum, I've made the "is this prime" game easier and much much harder
Video description: starting with a screen titled "Is this a quiz?", a series of questions: Is 7 a number? Is 0 a number? Is 9 a number? Is 3 even? Is 6 even? Then "Game over", and I let out a deep sigh.
@modeltheorist I don't, and I spent a long time looking for any last year
@modeltheorist although @pkrautz might know of some that aren't completely terrible
@sigfpe I don't think I agree with this. There can absolutely still be gatekeeping even if the person being kept out has a good understanding of the topic they're being kept out of.
@Desmos is desmos.com/accessibility the same page that used to be at learn.desmos.com/accessibility ?
@sigfpe I suppose it depends on whether the question is "Can I learn this?" or "Can I talk with someone else about this?" For the latter, you can gatekeep by rejecting someone if they learnt the thing from blog posts or whatever.
Me, every few months: I should make the @NclNumbas look more like these cool edtech things I keep seeing!
Moments later: oh, they're terrible for accessibility
@aperfect what did you think caused CSS resources to be loaded, or had you just never thought about it?
@aperfect yeah, it definitely doesn't happen when the CSS is read, because then you wouldn't need to think about pre-loading
(and you'd need to have the stuff to handle resources references in an element's style attribute anyway)
@aperfect while we're talking about frontend matters: I just decided to look at a domain I used to own, takenot.es. The right-pointing arrow is implemented as a ligature of the text 'arrow_forward' a custom font!!

Gang, I think I'm going to start putting a little bit of space between things that are multiplied together
@sangwinc let's not get ahead of ourselves!
I've been thinking about how sensitive we are to spacing as providing semantic information. I expected adding a bit of space to look completely wrong, but it was the opposite!
@sangwinc ta!
@MathsTechnology @geogebra interesting! Do you know if it's always done that?
@MathsTechnology @geogebra aha! Numbas does the same, but students continually get tripped up by it. I suppose the immediate feedback of the geometry bit not looking right is more noticeable than just the rendering of the notation
@RyanTinsleyPhys No?
@apgox @MathsTechnology @geogebra I think Mathematica is forced to do this because it doesn't do as much with spacing in its rendering as TeX does.
Now I wonder if Knuth has written anything on the subject

In Python, you can filter a list comprehension by adding an if statement to the end, e.g.:
[x for x in list if x<y]
I wish you could do the same in a for loop, e.g.:
for x in list if x<y:
...print(x)
@pippinsboss @Mathematical_A Nice!
@Mathematical_A your website is down: I get "The service is unavailable" when I try to load m-a.org.uk, or any page under it.
@dginev yes!
@bbarber_ I don't like the two instances of 'for', and there's a reason comprehensions replaced filter and map
@MathsImpact I've actually had people tell me quite firmly that • shouldn't be used for scalar multiplication at certain levels in order to avoid confusing students when they see vector dot product

@JM_Field5 I got a leaflet through the door for a company offering this, and I was like - when in this geological epoch has there not been enough water to grow grass in the north of England??

Are there any more too-clever acronyms for nerdsports around the world?
@Mathematical_A thanks!
@pippinsboss @Mathematical_A is there any chance you could send me a copy of that article?
@pippinsboss @Mathematical_A done!
@DavidB52s @MathsImpact I don't agree with this attitude. If the notation doesn't make the difference clear, we should try to improve the notation
@SpookySpctrlSeq @pwr2dppl The correct answer is "problems"
@robinhouston @LucasVB 'Shortlex' is what I've always used

I'm trying to do some writing about the design of @NclNumbas.
So far, I've written drafts of two articles.

University homepages should make it easy to check if a certain person still works there. Academics move around so much, and the continued existence of a personal homepage on the uni's domain isn't always evidence they're still there!

If I said "the gender pay gap is 15%", does that mean men are paid 15% more than women, or women are paid 15% less than men?
(assume wlog men are paid more than women)
@linguanumerate @phc27x @sam_power_825 yes, that's how I've always interpreted it.
It just occurred to me that someone wanting to make more of an impact would use percentage of women's pay, which would give a bigger number. But "pay gap of 200%" when men earn 3× as much would raise eyebrows, so maybe that's why
Following on from this: should percentage differences always be given in terms of the bigger quantity, unless you explicitly use the words "more" or "less"?
@piplustwo how do you make the distinction? You could say salaries are positively biased towards men.
That would make sense if looking at a job traditionally performed by women, which men start doing, and they get paid more. Programming could be an example of that.

18 months in, I still don't know how to end a work video call in a non-awkward fashion

People who say ambiguous equations should just have more symbols in them: what do you do about this?
@JDHamkins @pkrautz Or the other option is to introduce a symbol separating columns in a matrix
@hartkp ooh, here's a challenge then: categorise these as column vector, square matrix, or invalid due to spacing
@BernhardWerner @JDHamkins so in a world where a small unary minus means negation, are the left-hand sides of my equations in the picture above equivalent?
@JDHamkins @pkrautz I have a feeling @howie_hua has tweeted something about this in the past and I sort of agreed with it but couldn't quite be bothered to actually follow through and do it
@JDHamkins @BernhardWerner how do you resolve these ambiguities in handwriting?
@Smylers2 @JDHamkins @pkrautz my thoughts exactly!
@JDHamkins @BernhardWerner I think my point is, given that reliably getting spacing right is hard: shouldn't we do make a mark like sticking a comma between entries in a row, to make it clearer?
@JDHamkins @pkrautz @howie_hua Here's Florian Cajori on the subject. I endorse none of these solutions!

@logopetria There are often alternatives to sub/superscripts: some people write exp(long thing) instead of e^{long thing}, for example, to avoid putting too much in a superscript.
Is there an alternative notation for this situation?
This thread brought to you by whystartat.xyz/wiki/Space_is_….
Summary of solutions offered:
* use a smaller dash for "negative" and longer for "minus"
* superscript dash for "negative"
* get really good at judging spacing by eye
* go big on column padding

are there other sequences of operations built by repeating the previous one that are all commutative?

Suggestions for mathematical diagrams that you might want to assess a student's interaction with, please. Interaction could be moving objects in the diagram, typing a number or formula in a box, or ticking checkboxes.
So far I've got...
Placing objects on a Venn diagram: drag a point to an appropriate position, or tick boxes representing membership in each of the sets.
Move a point to given coordinates: drag a point on a grid, or type in Cartesian coordinates
I suppose I should just take a wander round geogebra.org...
Make a spanning tree: include/exclude edges of a graph by clicking them or toggling checkboxes.
Label parts of a diagram: move labels next to the corresponding objects
@BernhardWerner at the moment I'm looking at stuff that can be assessed, i.e. cases where you give the student a score based on what they did

International Tell Someone You Love That Excel Is Not The Right Medium For Forms Day
@chadtopaz @pwr2dppl I'm intrigued by the possibility of other chicken recipes that don't involve killing it first.
this form contains checkboxes (reasonable: it's a form) which web excel doesn't support (reasonable: spreadsheets are for text) so I have to log in to the Virtual Desktop to load desktop Excel (unreasonable: we have like three official ways of making forms, one made in-house)

Before I click on this headline: mean or median?
And follow-up question: how far apart are they?
I'll click on the link at midday. My mind is a blur of possibilities!
In the vein of artisanal integers, such as brooklynintegers.com, I'd like to start producing artisanal proofs, where "wlog" stands for *with* loss of generality!
Anyone want to take median and enrich Paul? twitter.com/ptwiddle/statu…
Just typed the sentence "in this measurement, large outliers are common".
How do I phrase that so it's not an oxymoron? Like, quite often when you collect this data, there's an outlier.
well, I've clicked on the link: bbc.co.uk/news/business-…
It doesn't specify mean or median, but gives a more precise figure of £78.54, which couldn't be the median unless there are some very fancy ATMs
@PaulsPrattle I'm describing what you're likely to see in a scatter graph, so not that
@dandersod I like the way you think
Currently in the audience of a Zoom talk. The number of different notifications coming through the speaker's mic are stressing me out.
Dude, I think you're too busy to speak to us!
whoah, I've just noticed that Neil Sloane mentioned one of my integer sequences in a talk at Doron Zeilberger's experimental math class! oeis.org/A268176/a26817…
If coming up with questions was as hard as answering them, I'd feel a real sense of achievement now
and looking through the history, I see it's a classic CLP OEIS submission: I was fiddling around following an aesthetic, and the incredibly patient editors fixed it until it was presentable.
@jjsanderson Would you like someone to talk it through with?
While trying not to scratch the chicken pox I've somehow caught for the second time, I wondered why so many medically unlikely things happen to me.
But then I channelled my inner @d_spiegel and thought: how many rare illnesses should I expect to have in my lifetime?
How many "1 in 1000" illnesses should I expect to have? If they're independent of each other and I'm no more susceptible than average, it still depends on how many different illnesses they are.
If there are 1000, I should expect to catch 1, and shouldn't be surprised if I catch 2
A list of all the characters you can use to write words is called an alphabet or a syllabary.
What is the list of characters you can use to write numbers called? Is there a name?
first algebraist to say 'alphabet' is getting blocked
@madebyburton I only know that as an adjective. Is it also a noun?
@BernhardWerner following 'syllabary', I think I like 'digitary'
Challenge: starting from durham.ac.uk, get to durham.ac.uk/departments/ac… only by clicking on links.
There *must* be something I'm missing!
Expanding the challenge to typing in the search box, even "mathematics department" doesn't get it on the first page of results!
@JonathanHoefler ah yes, thanks. I spent a while trying to remember if I know the difference between 'digit' and 'numeral', and forgot about 'figure'.
So is there a name for the set of figures?
@SimonVonDulwich ahhh, that's where it's hiding! Thanks!
Did you do this on mobile? I think on desktop the large nav at the top is much more prominent than those links in the footer
@JonathanHoefler thanks!
I'm still not sure if this scratches my itch: I can say "the figures", but I can't say "a figures".
Like: "the Welsh alphabet has no X", vs "the Roman <set of figures> has no 0". I want one word for "set of figures", and apparently I'm willing to waste a day finding it
@JonathanHoefler can you explain how it's imprecise? I know nothing and I don't think I can see the distinction you're making
@mathzorro ah! I did just miss a link in the right place, then
@jjsanderson yes! I've yet to find someone who's happy with the way sharepoint works.
I think we should put the librarians in charge of the intranet.
@JonathanHoefler Thanks for indulging me with your expertise! I think I agree with most of that.
I'd consider √ more like punctuation than a letter of the alphabet.
I didn't really start with the "what's in the alphabet" question -
@JonathanHoefler ... it was more: when writing my salary, I use the 'digitary' 012345678798. When writing a binary number, I use the 'digitary' 01.
It's not about what they mean, it's about which digits can come up.
@JonathanHoefler me too! Have you seen my site whystartat.xyz ?
If you have any typography-related qualms to record there, I'd love to see them

TeX is a markup language for mathematics designed to be easy to type on a standard US physical keyboard.

I have protanopia: I'm really colourblind. I have a couple of apps on my phone which claim to name colours, but they don't work very well.
So I've had a go at making my own, as an easy to remember web page: what-colour-is-that.glitch.me
all the apps I've used before make the same few mistakes: they give only one colour name, with no confidence estimate, and the list of colours is often _way_ more specific than I can deal with
my page takes a rolling average over the last few frames, so it doesn't bounce around so much. It shows the top 5 guesses, along with bars showing how confident it is. I've limited the list of colour names to those from simple wikipedia: simple.wikipedia.org/wiki/Colour
I went further and weighted some of the colour names, so you have to be _really_ close to 'teal' for that to be the best guess, but 'red', 'green' and 'blue' come top more easily.
I suspect that the apps I've used in the past just use Euclidean distance in RGB colour space to work out closeness. I've used the CIEDE2000 metric, which is supposed to better match how humans with normal colour vision perceive difference
the last thing is that the camera display only takes up a small portion of the screen; the rest is filled with whatever colour it's naming at the moment - it really helps to check that it's working properly!
@CharlesDWimmer Yeah, next time the baby has a nap I'm going to look into whether I can control the camera's exposure

#GoodAtMyJob
#BadAtReadingEmails
is there a word for when a term signifying a divisive topic becomes acceptable, and then starts being used for so many different things it loses almost all meaning?
A recent example I'm thinking of is 'decolonisation', and I suppose before that 'diversity'.
it seems like all of a sudden decolonisation has become A Thing We Are Going To Do, but I don't get the sense that many people saying that have a clear idea what they mean
I first heard it in South Africa in 2016, where students were trying to force their universities to examine where the material they taught came from, and use traditionally local ways of knowledge more. That felt easy to understand, and definitely didn't have institutional support
now here in Newcastle, I've been in so many meetings and events where decolonisation was mentioned, and it seems to be boiling down to 'teach history', and the people talking about it are largely like me, white and British.
@linguanumerate my first feeling was that it's some kind of saturation: the sum of everyone's understanding of what the term means eventually encompasses everything
I think this also happens a lot in tech, whenever there's a buzzword that is good to be associated with.
'The cloud' feels like it's lost whatever loose meaning it originally had.
'Hipster' has had a long and varied history, but it had a fairly specific meaning in the early 2000s, before expanding to mean 'anything new I don't like'
@linguanumerate I agree!
@GwendolynHuot thanks! I'll use that
oh, 0 unread emails at 10:00, but then I had a zoom meeting and forgot to tweet.
I drastically overestimated the importance of the emails I hadn't read!
@sarahlovesmaths hah, that's a good way of viewing it!
Do my literature review for me before I do this experiment:
ask students to write out a proof, then show them a marking rubric and ask them to mark their own proof. Compare against a normal marker's marking. Are the students' marks fair and reliable at all?
Has anyone done this before? I've seen peer grading, but can't remember seeing self-marking for mathematical proofs. I reckon it's probably been done, though.
@sangwinc ?
@heavymetalmaths That's a much posher cover than the one on my copy!
@chadtopaz I'd like that on a t-shirt (on the back, obv)
What tool should I be using for this job?
I'm conducting a survey of things, to compare with each other. For each thing, I record a name and some arbitrary notes, then I have a long list of yes/no questions to answer.
(1/n)
For a given set of answers to some of the questions, I'd like to be able to quickly see which things match. Additionally, some questions only make sense if the answer to another question was 'yes', so I'd like not to see them for things where the answer is 'no'.
(2/n)
At the moment, I've got a spreadsheet. I don't think I can do the grouping easily, and it's hard to store and read long passages of text for the notes.
In the 90s, I'd consider using something like Access. Can a diagramming tool like Miro do the automatic grouping?
The other option I can think of is to have a load of pieces of paper that I shuffle about, but:
1) I want a tidy desk
2) this feels like the one job that computers were invented for.
All suggestions welcome!

@DavidKButlerUoA Here's what I think is an OK proof. It took me a bit of thinking, and you'll note this is a day after I first saw your tweet! But I don't think it's obtuse. I can remember seeing a problem like this in the past that made thinking in vectors 'click' for me.

@DavidKButlerUoA I can't immediately think of a way of proving it without vectors, by the way. It's just what you're familiar with, I reckon

@DavidKButlerUoA @Whitehughes in your video it felt like you spent ages not noticing that you had an equation for MC that you could rearrange.
I think my internal monologue looks for paths between two points, and then you write down the path as a sum of the vectors along it.
@icecolbeveridge @DavidKButlerUoA I think you have in spirit the same solution as me. I spent most of my time unsure if I could expand out the dot product, and then wondering where I'd used the isosceles property before remembering a.a = |a|², so I need |a| = |b| (I first had a.a = 1)

@madebyburton would you mind having a go at something a bit harder?
@DavidKButlerUoA @Whitehughes I had a strong sense while going through my solution that I was really just repeating a similar example I'd seen before. I tried to mention the points where I'd made a decision or needed to check something, but I definitely skipped explaining some bits
@DavidKButlerUoA @Whitehughes I suppose mathematical fluency is having that stock of stuff you use without really thinking about it
@peterrowlett how are you delivering your coursebuilder stuff to students? Do you just upload it to some webspace? Do you do anything to control access?
@peterrowlett yes please! Actually, are you free now to join a zoom call?
@madebyburton Thanks, that's really helpful!
@DavidKButlerUoA @Whitehughes I agree, but given that exams exist, my perspective is that producing a proof demonstrates fluency, which is what you want students to end up with. It's a high bar to clear, so in a large general service course it shouldn't make up too much of the available credit
@madebyburton Ooh, now I'd be very interested in seeing what trouble you had

Europeans! You use a comma for the decimal separator, like π = 3,14159... which is FINE.
But what do you do for functions of more than one variable?
Like: f(x,t) = t(1,23, 4,56) ???
@BarbaraFantechi So you'd use a comma unless there's a non-integer number as one of the parameters?
@villares Always, or just when a comma would cause a problem?
So far, the answers here are much more consistent with each other than on mastodon: mathstodon.xyz/@christianp/10…

A little thread about an extremely simple web-based slideshow I made for my @BigMathsJam talk yesterday.
You can see it at somethingorotherwhatever.com/each-edge-peac…
I wanted to show a little bit of text next to a graphic that changes on each slide.
reveal.js is 10 years old now, and the way it works has changed a bit to keep up with new stuff in browsers. So each time I make a presentation, I have to decide if I'm going to update reveal.js, and see if it's got a way of doing something I had to hack in before
For years I've been using reveal.js for presentations, because I do _not_ get on with powerpoint, and I often want to embed web stuff. It's really good, but there's always a point where I get frustrated trying to lay stuff out.
What do you do when you don't understand how a complicated bit of software works? Write your own copy from scratch!
Then you have only yourself to blame.
My solution lately has been to use CSS display: grid on slides, because I know how to centre stuff and share out space in a fairly straightforward manner.
But it's always a faff, and reveal.js is now so big I spend a lot of time trying to understand how it works
I came up with something very simple: each slide is a <section> tag, styled to 100vh height and laid out vertically, so you only see one at a time. They have tabindex="0" so you move between them by pressing Tab.
The thing that got me this time was having the same graphic displayed on a range of slides, and updating it depending on which slide is shown. I spent a couple of hours fiddling with reveal.js's events API before giving up.
To update the graphic, I added a 'focus' event listener to each <section> tag, calling a function 'update_graph' with the index of the tag among its siblings.
That's it! It worked brilliantly.
I was expecting to have to write a thing to call scrollIntoView on the next slide, but Firefox automatically scrolls an element into view when you focus it, so I got the fundamentals of a slideshow without any JS!
This time, there were no links or interactive bits in the slides that people might want to access on their own, do I just needed it to work for me during the presentation.
I think for a set of slides I want other people to be able to use, it'd need more stuff: at the moment it only knows which slide is shown from focus events, but it should really pay attention to scrolling too.
Anyway, I'm not going to make any effort to share this system for other people to make presentations with.
The point is that it's idiosyncratic, a product of exactly the things I know how to do and don't know how to do.
@pwr2dppl I think the answer is to have 8 hours of sleep, but I get the feeling that's not the answer you want

@alisonkiddle the livestream broke during your talk yesterday. I have a backup recording of my screen, but it turns out the audio is just of my mic, so there's lots of typing noise on top of your speech. Do you want me to put it up with the stream for 72 hours, or just forget it?
@alisonkiddle okie dokes!
@Tony_Mann the livestream broke during your talk yesterday. I have a backup recording of my screen, but it turns out the audio is just of my mic, so there's lots of typing noise on top of your speech. Do you want me to put it up with the stream for 72 hours, or just forget it?
@Tony_Mann if you want a permanent recording, best to do it again, but just for the 72 hours the livestreams are available, I reckon my recording is good enough
thanks to @pkrautz for telling me about CSS scroll-snap, which lets me insist that you can't scroll halfway between slides. I've replaced the focus listener with a scroll listener, so this now works nicely with just scrolling!
I have an HTML question I either don't know how to google or nobody has asked before:
I have a web-based editor for a content bank. Users can write HTML descriptions for items, which will be shown on a details page. They might want to use heading tags in their description. (1/2)
What should I do with heading tags so they don't mess up the page navigation when the description is embedded in a page? Shift everything down, so h1 → h3, h2 → h4, ...? Just leave them as they are? (2/2)
@jtombs could do, but I feel like assuming the text will always be displayed under a certain heading level is wrong

@DavidKButlerUoA My immediate reaction to this "brainteaser" was that it's one of those "invent and prove the theorem I'm thinking of" ones, and it doesn't look like I was wrong!
I have a feeling @robeastaway has a name for these
Here's how it looks now. I hadn't realised at first that the order of the inputs matters!
@ben_nuttall Elm
@eigenbros Well, both. I want to see if it's easier to use on my phone than a standard calculator, for situations where you want to repeat a calculation with different inputs
@onio72 Elm. I've put the code on @glitch: floating-point-calculator.glitch.me
@howie_hua This might be your best one yet
I've put this on @glitch at floating-point-calculator.glitch.me
It now works with touch screens. Next is to add keyboard input
@KangarooPhysics @glitch Yeah, arrows would be helpful. Solving backwards is an interesting idea!

Just discovered that on Ubuntu if you press the play media button on your keyboard after failing to pick up a MS Teams call, it plays the ringtone on loop despite there being no call any more.
@Htbaa I think this is a "hastily put together an Electron app" bug rather than a linux problem
@Htbaa oddly, I wasn't motivated to find out
Tomorrow I'm giving a maths talk to a load of 15/16 year olds. It's a talk I last gave in 2014, so I've updated it a bit.
I've put my slides online at staff.ncl.ac.uk/christian.perf….
What do you think? (Obviously you don't know what I'll say about them!)
The talk went really well last time, so I didn't want to change too much. One thing I'm really struck by now is that every character in the story, including me, is a white man. I'm not sure what to do about that.
I'll tell the kids that the story took place in a time when you pretty much had to be a well-off white man to dedicate time to maths and have me end up knowing about it.
@PaddyMaths Yes, I suppose quickly showing a couple of contemporary people would get that point across, even if I'm not showing any maths attributed to them
December
For comparison, here are the slides I used in 2014: staff.ncl.ac.uk/christian.perf…

@neheritagelib My parents moved to Washington ~40 years ago because they thought the metro was going there. Alas not!
@CMoore_84 That's really nice to hear, thanks!
Just for a laugh,
Let G be a graph,
With points called P
And edges called E.
Now draw a line
(just anywhere's fine)
And split up P,
Some for you, some me.
Now look at E,
And how it links P.
If every line
Connects yours to mine,
That graph called G?
Bipartite. QED!
@RichardElwes Ahh, you're right! I tried to avoid exactly that, but clearly failed in the last iteration
Pals, @Tegglington has just told me that in Japan they don't use ✓ for "correct", they use 〇.
What other symbols for "correct" and "incorrect" are used around the world?
@BernhardWerner What's in the lookup tables?
@evelynjlamb @yenergy Whoah, now there's an idea!
@evelynjlamb @yenergy though if you're looking for uses for leftover fat, look no further than British cooking
@john_overholt I did, one year
It now looks like this. It takes physical and on-screen keyboard input. I spent a fruitless hour trying to get pinch-to-zoom to work.
@mathforge Yes, @KangarooPhysics asked for arrows too. Will do
@mathforge @KangarooPhysics like this?

People with working colour vision who use the web-based Outlook: is the "selected email" colour easy to distinguish from the normal white background? I've just scrolled up and down my inbox half a dozen times trying to find the email I'm looking at!
I've set up a blank page with the left half that colour, and I honestly couldn't tell if I'd set it up properly! It all looks flat white to me.
Naming Your Child After Irish Counties
Clare: lovely
Kerry: also fine
Mayo: audacious
between 1996 and 2015, the only Irish county names given to children born in the UK were:
Cavan (572)
Clare (1062)
Kerry (38)
Tyrone (1445)
I know many Clares and zero Cavans. Are regional averages on the primary SPaG test published, so I know where to look for them?
@suedepom was it immediately clear there are two parts, or did you have to stare for a bit?
@sxpmaths ooh, is that a thing? Thanks for the hint!

Exciting unintended typography! Using the League of Moveable Type's Junction font, the word "office" looks like "offfice", I guess because it applies an ff ligature and then an fi ligature.

An unexpected logic puzzle, thanks to the baby: can you say how many lids are in the wrong place?

What should I change A to so that the number at the top is an integer?
Or what should I change B to? Or C?
@jjaron is anyone maintaining a page listing the day's scandals, like the one for Trump?
@Smylers2 there's a solution for B that you might call trivial. Or: nobody said B has to be an integer
@Smylers2 if you do want B to be an integer, then does B = (A-1)·C feel justifiable?

I have five stacks of three blocks. I can join two stacks together, or split a stack.
How many splits and joins do I need to do to end up with three stacks of five blocks?
My real question is: for A stacks of B blocks into B stacks of A blocks, is it ever the case that the strategy that minimises joins is not the same as the strategy that minimises splits?
@eduardojdiniz Yes - to go backwards, swap splits and joins

@wtgowers here's the Numbas Eukleides code I wrote to produce the diagram: gist.github.com/christianp/278…

@DrJessBoland (I have a budget, obv)
I've realised that I don't know what this shape looks like. I will tweet first, make a guess, then do some simulations.
You launch a projectile into the air. If you only know the launch angle and speed roughly, where could it be after T seconds?
My thoughts:
T=0: at the origin.
T→∞: An interval around a point on the ground.
Other T: something like an ellipse, maybe squashed against the ground. I don't think it has to be convex.
@BernhardWerner yes!
I've made a @geogebra worksheet. Point A is the position of the projectile, and B controls the launch angle and speed. I've turned on trace for both.
When B traces a square, A traces a windscreen wiper shape. Makes sense!
Here's the geogebra worksheet: geogebra.org/calculator/gfg…
I couldn't be bothered to work out how to repeat the calculation over many points in geogebra, so here's a video from a different tool, showing a smattering of points over time. I wasn't sure before seeing this whether the shape changes before and after the top of the parabola

@DavidKButlerUoA Interesting! Maybe I got lucky with my line of thought then.
Since those triangles are right-angled and congruent, I thought you can make a rectangle from two of them. From there I was confident I'd have everything I needed after writing down the rectangle's area
@DavidKButlerUoA Sides of the rectangle are cos(x) and sin(x).
Its area is 1/4.
So sin(x)cos(x) =1/4.
Doible angle formula: sin(2x)=2sin(x)cos(x)
So sin(2x)=1/2.
Used a calculator to find x=15°
@DavidKButlerUoA Bits I used from memory:
When you have right-angled triangles, try making a whole rectangle.
sin(x)cos(x) has something to do with double angle formulas (had to look up if it was sin or cos)
Couldn't be bothered to work out arcsin(1/2), so used a calculator
@DavidKButlerUoA Exactly!

@zithral Can you make table of which tin each mix will go into? I'm colourblind so never learnt!
@zithral The model I imagine is: colours are triples (r, y, b), with white = (1,1,1). Mixing colours is taking the minimum of each component.
Is that what you thought?

@DavidKButlerUoA What's yours? Mine was ODEs
"1 garlic clove, halved"
Whoah, slow down there, cowboy!
@zithral @DavidKButlerUoA I think the numbering normally goes in the order the matches happen, so \1 is the first group matched, \2 is the second, and so on
@zithral @DavidKButlerUoA so if the input is "hello hell" and the regex is "(he)(l+)o \1\2", then \1 matches the other instance of "he" and \2 matches the other instance of "ll"
@DavidKButlerUoA @zithral I have seen that somewhere, but can't think where!

Since John found this, it reminds me of a question about it: following the rules of this game, is it true that any division of the square into rectangles can be draggy-boxed back to the whole square? twitter.com/mathhombre/sta…
@Skippa23 I just loaded it on my phone and realised that I never added support for touch screens! So if you're on a phone too, that'll be why
@Skippa23 now fixed!
and now I've played the game again, I have an answer to my question. I won't put it here, in case anyone else wants to think about it
@htfb literally just adding in touch screen support now. Try reloading, and tell me if it's any better?
you: python lists are zero-indexed

@NclNumbas Well, big shot, if seq[0] gets the first item in the list, why doesn't seq[-0] get the last item?
@NclNumbas having a totally normal one
@pwr2dppl it's a song by Des'ree
@htfb yeah, it needs a bigger margin of error for touches.
That wikipedia page doesn't give an explicit answer either way, does it?
I have a v simple example in mind
@htfb yep
@htfb next question: given an initial division which can be reduced to the whole square, is it possible to merge rectangles so that you get stuck?
Again, I have a simple example in mind
@TimHarford I think you have to declare your colour model before that question can be answered. You could justify saying the average would be white, or grey, or even black, depending on how you combine colours

@stecks @blatherwick_sam oh yikes, me too!
@stecks @blatherwick_sam yeah, and I meant to add in some weighting to it so the expected number of rectangles is finite
@blatherwick_sam @DavidKButlerUoA No, it wouldn't! I was hoping someone would notice that
"Subtract a from b" = "b - a"
"Divide a by b" = "a ÷ b"
Is there a phrase equivalent to "b ÷ a" where a occurs before b?
@Cshearer41 I've never understood what that means! Thanks!
@mathsjem so "divide three into six" gives 2?
I've never understood "divide into" so avoid it. Is "divide six into threes" a thing, and does it give 2?

Not sure how to feel about the fact that the rate at which I make things, as measured by my homepage, has been pretty much constant since 2011
@stecks That wasn't an 'if and only if', so there's still a chance you're happy
@zithral I think 125 = 5³ is the smallest integer with an abbreviation:
Smallest such integer must have at least 3 digits. Abbreviations must have at least 2 digits. All products and squares of two digits < 100. All higher powers of 2,3,4 are > 125
@zithral Is this question related to Kolmogorov complexity?
@htfb @zithral This has rung a faint bell about how you can make everything from a single 4, with repeated factorials, roots, and rounding
Suppose you have all the numbers, but the only thing you know how to do with them is
m(x, y, z) = min(x+y, x+z, y+z)
Given any x and y, can you produce x+y using only m?
#IHaveAnAnswer
(no, infinity is not a number you can put into m)
@langtoneagle Yes, you can name any constant
@langtoneagle Maybe the most straightforward way of stating that constraint is: you have to commit to which other numbers you're going to use before I give you x and y
@yet_so_far After how many steps?
@mscroggs Nice! And what if you can only check for equality with x or y? Or can't check for equality at all?
@yet_so_far In order to know when to stop, you have to know how to compare two numbers. If you can't do that, is it still possible?
@yet_so_far @virtualcourtney I deliberately left it vague! I like how there are different answers for different sets of numbers
I have half a joke in my head, but I can't remember the rest of it.
It's something like: <famous mathematician X> said they could tell me all the digits of pi. It went:
3 <wait a second>, 1 <wait 2 seconds>, 4 <wait 4 seconds>, ...
Does that ring any bells with anyone?
@logopetria Yes! That's it!
@icecolbeveridge oh yes, I think I've heard that one too.
But $1 after 1 day, another dollar two days later, then three days later, ... would avoid paying impossibly small amounts

@DavidKButlerUoA You've certainly spent longer thinking about it than I did! Thanks for having a go.
I hope you have less tough days ahead of you
@zithral or, you could repeatedly pick from a range that might contain non-abbreviable numbers, until you get one that is abbreviable
@DavidKButlerUoA You're not going to like it! I'm pretty sure you need some way of comparing numbers or testing for equality.
The answer I had starts with m(x, y, 0) and either give you min(x, y) or x+y. So if you can test for equality you can pick one of m(x, y, x), m(x, y, y) or m(x, y, 0)

Then <dead_greek> <p> gets π

@jtombs I think I remember @howie_hua or @JimPropp tweeting about this in the past. We should form a club
@howie_hua @jtombs @JimPropp yes!
Thinking about the Lousy Labelling puzzle that @DavidKButlerUoA tweeted about. It can't be a coincidence that there are 6 permutations of three boxes, and this table has 6 entries
Can it? Maybe it is!
Anyway, this puzzle also reminds me that derangements - permutations where nothing stays still - are hard to count

@peterrowlett Not pictured: the tile picturing all sets not pictured on any tile
@peterrowlett Uh oh. I verbed 'picture' too much and now I don't know what I can verb any more
@henryseg @MathMechs @willsegerman That is really cool!
@peterrowlett Well obviously the episode I was on was no good, so I'm gratified to hear that other guests did a better job

I use an OTP app for two-factor authentication for all sorts of things.
It comes up with a new 6-digit code every few seconds.
This question occurred to me: is it possible for it to come up with the same code twice in a row?
@mountain_ghosts 6 digits is only a million possibilities, so in absolute terms it must be quite common, even if I personally am unlikely to see it, right?
@mountain_ghosts what do I look like, some kind of curious person with both the means and know-how to investigate this? I'll stick to idle speculation on twitter.com thank you
I found an OTP library to test this, and you do indeed get repeats! You'd expect to repeat the last code once in a million times. Codes normally last 30 seconds, so expect 1 repeat per ~348 days, so just about once a year.
I'm now convinced that someone will see this happen.
@icecolbeveridge I've got about a dozen services in my OTP app, so it actually works!
@schrisomalis I'd always thought it was a regional thing from some region I'm not familiar with. I hadn't considered that it might just be a global change!
@peterrowlett Oh, good point - two accounts making the same code at the same time would be easier to notice

Can't believe it's been 10 years. Feels like both forever and no time at all. twitter.com/aperiodical/st…
My favourite bits on The Aperiodical that I was responsible for:
1) It all started with a column on @Samuel_Hansen's blog, The Internet Maths Aperiodical - a collection of random maths stuff I'd seen. I moved those over to aperiodical.com: aperiodical.com/category/colum…
2) The integer sequence reviews I did with @TweetsofCushing: aperiodical.com/category/colum…. Pure delight! Completely self-indulgent, although it led to..
.. a @numberphile video!
youtube.com/watch?v=VDD6FD…
We weren't prepared for how seriously people took the competition, and I think fiddling the winner so it'd fit on a trophy might have been the wrong thing to do
3) The #BigMathOff: aperiodical.com/category/the-b…
Plan: get people to tell me fun maths facts.
Result: I can call @ch_nira The World's Most Interesting Mathematician and everyone else goes along with it?
4) This gif, on the "Riemann hypothesis not proved" post, which continued to get a steady stream of attention for several years.

5) The Nonsense Formula Disapprove-o-Matic 3000, which would be wheeled into action whenever the words "formula for the perfect ..." appeared in a newspaper.
It hasn't disapproved of anything in a while, but it is ready and waiting aperiodical.com/?s=disapprove-…
6) My post on the lullaby sequence. @aap03102 said "The way Christian tells this is completely charming". I don't think I'll do any better than that.

I don't have much time to write my own stuff these days, but I hope the site keeps going as a place for keen maths fans to put stuff and have a load of other maths fans see it.
But those are just the things I did. The thing I'm most proud of is the huge gang of other people who have used the site to share their own fun maths over the years, and the connections it's helped to make.

@chris_fairless That's vacuously correct?
A while ago over on Mastodon @davidphys1@mathstodon.xyz asked why nobody had made animations of the shunting yard algorithm with cutesy trains.
There is no surer way to summon me!
I've spent some of my spare time over the bank holidays making exactly that: somethingorotherwhatever.com/shunting-yard-…
The core problem is that you need to work out what just what an operator applies to: with the order of operations, it might be just one number, or it might a large sub-expression.
The algorithm solves this by holding operators on a separate stack until they're needed.
The shunting yard algorithm neatly solves the problem of translating a mathematical expression written in infix notation (operators go between the numbers/letters) to postfix notation (operators go after the things they act on).
youtube.com/watch?v=gHniHE…
Here are some animations to illustrate.
In the first, operations happen left-to-right, so they appear in the same order in the output as in the input.
In the second, the addition must happen after the multiplication, so it's held back.
In the third, brackets ensure that the addition happens first.
The last wrinkle for standard arithmetic is that exponentiation is right-associative: while for the other operations you work left-to-right:
1 − 2 − 3 = (1 − 2) − 3,
the order goes the other way for exponentiation:
1 ^ 2 ^ 3 = 1 ^ (2 ^ 3)

Near me, Newcastle and Teesside International airports are 60km apart. Flying between them in a private jet would take about 4 minutes
@yet_so_far I've seen elsewhere that the owners probably aren't on these flights: the planes are being moved either for maintenance or to be closer to the passengers.
I suppose if you've got money to literally burn, saving yourself a 40 minute drive to the big airport is worthwhile

"average person proves 3 theorems a year" factoid actualy just statistical error. average person proves 0 theorems per year. Carl Gauss, who lives in cave & proves over 10,000 each day, is an outlier adn should not have been counted
@ZoeLGriffiths @edsouthall We said that about my daughter, and at nearly 5, she's still got very blonde hair
@edsouthall My sister-in-law, during the short time that she was a barmaid, poured a pint of whiskey.
@josstified I just can't see whose vote he's trying to get. Mean-spirited people who voted Tory last time, but somehow would switch to labour instead of the lib dems?
There's no angle from which a dodecahedron looks like a regular solid.
I'm organising a series of online public maths talks through @NCLMathsStats to be delivered by disabled presenters, taking place this December.
Talks can be any mathy topic, or about your experience as a disabled mathematician.
I need speakers: dm me if interested!
@NCLMathsStats To give some idea of what I'm looking for, I'll use myself as an example.
I count myself disabled at least four ways: I'm colourblind, autistic, dyspraxic, and have Ehlers-Danlos.
I might talk about:
@NCLMathsStats 1) use of colour in mathematical communication; how red chalk makes chalk-and-talks inaccessible
2) how ambiguously-worded maths problems have stymied me in the past, and how to write them more clearly
3) the word problem in group theory, which is just something I'm interested in
@OUMathsStats @NCLMathsStats yep: christian.perfect@ncl.ac.uk
@NCLMathsStats This came about because I and some other disabled people who do maths talks got tired of missing out on opportunities to do outreach because it involves travelling.
If you're interested in taking part, either dm me or email christian.perfect@ncl.ac.uk
@rasjor That's new to me, thanks!
@neheritagelib It's a superb name
@DrCaroSummers @scienceatlife Thanks for reminding me that we talked about going this summer! I haven't been in years, and none of the other L-Ps have been at all
@HedronApp Nah, looks weird
@stecks are you aware of this robot-themed diner? twitter.com/MrPJEvans/stat…
@SophieBays Deservedly so! I still dig out your videos to talk about probability things with non-maths people

@CardColm with the graphicx package, you can do \rotatebox, but why do you want to do this?

@ch_nira @aperiodical Best poorly-thought-out plan I've ever put into action. You've made it your own thing!

@gazza_d crikey, how fast do you pedal? It takes me over an hour to do the 8ish miles into Newcastle from Whitley Bay
@gazza_d hat's off to you!
Does anyone know if it's possible to get google maps or openstreetmap or similar to plot a route between two places, and show where you'd be at regular time intervals? Like, where you'd be after 5 mins, 10 mins, etc.

@SparksMaths @panlepan degenerate, naughty hexagons
@SparksMaths @panlepan @geogebra is there an easy way in geogebra of creating a periodic tiling of a given shape?
@panlepan @SparksMaths @geogebra thanks!
@panlepan @SparksMaths @geogebra is there a way to make the algebra editor not hateful? Like, don't delete everything between parentheses when I delete one parenthesis, and move sensibly with the arrow keys? It's set up for moving around 2D notation, but doesn't really manage it
@SparksMaths @panlepan @geogebra I think the root of the problems with the app's input is that it won't allow a syntactically incorrect expression at any point, so if you write or delete one parenthesis it necessarily has to add or remove the matching one. An incorrect constraint, I'd say!
@pwr2dppl I don't think I've seen that format, so I'm confused squared
@pwr2dppl My experience of following you here is like 50% "oh, that's an interesting point" and 50% no idea even what realm of human endeavour it's about!
@pwr2dppl (not a complaint)

@jjsanderson @DrLucyRogers I was about to make a quip about finding a public transport service using vehicles older than the tyne and wear metro, but wikipedia says they're still making new hovercraft!
@jjsanderson @DrLucyRogers I heard the first one's starting in October. Can't wait!
@jjsanderson this page says the first new train will run in November: nexus.org.uk/newmetrotrains
@jjsanderson oh no it doesn't, I can't read. It arrives for testing in November this year, and enters service November next year. Good grief!
@MattPDickinson lucky dog! Ours surprised us by having a lovely snooze in the car the whole way.

@Smylers2 I've noticed nationwide have started doing lots more authentication checks recently. I'll take an abundance of caution, given the arms race of ways to scam online payments
@Smylers2 I agree it seems to do the wrong thing fairly often, but I can believe it's a really hard thing to get right, and being more transparent about how it works would only help scammers.
Frustrating all round!
@HigherGeometer if you're using wordpress.com, you won't be able to use that plugin. And if you're on a host that can use plugins, you might as well use MathJax
@HigherGeometer having said that, something's not right on your site: wordpress is adding the fg and bg parameters to your latex, which suggests it's trying to automatically work them out. Is there anything in the appearance tab of the admin to set fg and bg colours?

What is ableism? It's this line on Alnwick Gardens's "visit us" page:
"you are able to park anywhere other than the first tier which is reserved for Blue Badge holders only"
Do Blue Badge holders infer that the rest of the page isn't written for them, either?
(By all accounts they do a very good job of inclusion and accessibility once you're there. This just leapt out at me as badly written copy!)

Zoinks! I just checked my salary. If UK higher education salaries had increased with inflation since 2009 I would now be earning £9,768.25 more per year. ucu.org.uk/HEpaymodeller #ucuRISING
(challenge for the keen beans: work out my current pay)
I did it again with the same current salary but 40 hours per week, and it said the same amount more. So I think it only asks for your hours worked to calculate an hourly rate. I wonder why it doesn't say what your hourly rate should be if it kept up with inflation
@LotoshaBrown @wacnt nice! Well done digging this up
In case you were wondering, 153 is the smallest integer whose factorial has two zeros after the leading digit. It *just* fits in a tweet - see below twitter.com/LotoshaBrown/s…
153! = 200634390509568239477828874698911718566246149616161171934231099284840946025238092339613294062603588435530393145048663047173051913507711632216305667129554900620296603188543122491838966881134795135997316305640071571629943041039657861120000000000000000000000000000000000000

@icecolbeveridge you're right, I only need an approximation!
@icecolbeveridge but Stirling's approximation doesn't seem to be close enough, unless I've misunderstood. And Python doesn't like making massive floats, so I have to be clever twice
@icecolbeveridge can I see your code?
@icecolbeveridge flaunting your coding skills and your kids' reasonable breakfast time at me. The cheek!
@icecolbeveridge oh, of course!
@icecolbeveridge could you make the counting-zeros bit quicker by chopping off the leading digit, then computing log10 of what's left?
@icecolbeveridge so what you're saying is you don't have seven 9s uptime?
@icecolbeveridge can you add any extra terms you get to oeis.org/draft/A356739 ?
@gregeganSF having spent most of yesterday watching dd copy 1TB of empty data from one disk to another, this is weirdly relatable
@icecolbeveridge I have half a mind to try this in constructive real arithmetic, where you say how many decimal places you want, and it automatically does the calculation only to the required accuracy. My implementation isn't designed for speed, though
@algorithmachine "how could we possibly reduce our APC????"
@NTCouncilTeam I had no idea there were places to recycle small electricals apart from the big tip. Thanks!
The problem with recycling batteries is that I get through them so slowly that by the time I've got enough to justify a trip to the recycling point, they've been sat on the shelf so long I feel I'll miss them when they're gone.

I'm not saying I expect the author, Alexander Huber, to fix this - I think this was just made for fun.
But when you're making stuff like this for work, you really need to consider basic accessibility problems like this.

@JanvierUK It's an any% run, that's for sure
A striking intervention by the 4-year-old following last night's scenes in Westminster.
Could this be the final straw for the tories?
I for one would like to welcome our new lettuce overlord
it worked! Fear the power of L-P 3!
@CardColm I was mistaken for an American outside that SPAR, by some actual Americans. Had to say "sorry, I'm one of the bad guys"
Just under a week to go until this happens. I've done some coding for the Guess Who game at 06:00, and I'm hosting "Blockbusters of Interesting Maths" at 09:00, with @stecks, @ColinTheMathmo and @alexcorner twitter.com/24hmaths/statu…
@jamestanton Are all the sentences red?
@edsouthall Someone found a worse use for rubber stamps than the Coordinate (aperiodical.com/2015/02/coordi…)
Just to clarify, because some confusion has arisen: the baby doesn't have a poo in his nappy, but his Duplo girl does. So if you can smell a poo, it's the Duplo girl who needs a change, not him.
Another avoidable maths accident. Don't let this happen to you.

@MrsDMaths @SamHartburn @SparksMaths there have been a few talks on Dobble at @BigMathsJam. The first one was @MB_Whitworth in 2012: mathsjam.com/assets/talks/2…
@pwr2dppl Replay the horrible real scenarios?
HIGNFrY! twitter.com/haveigotnews/s…
@24hmaths @stecks @ColinTheMathmo @alexcorner @mathmats It was a lot of fun!
The maths blockbusters board is online at maths-blockbuster.glitch.me, for anyone who wants to play at home
The 5-year-old wanted to ride her bike into Whitley Bay town centre. Going at her speed really makes it clear how difficult cycling is here. By the time we got to Station Road, I told her to go on the pavement because it's just not safe.
(I got off and walked)
@NTStreetLife
She really wanted to go along Park View and look at the shops (and maybe spend some money!) but she wouldn't be safe in the road, and I'd be a danger to pedestrians on the pavement. I really wish @NTCouncilTeam had kept the pedestrianisation - it was such a nice place to be
@sophiethemathmo massive high fives next time I see you. (and if you're not asleep yet: go to sleep!)
@pwr2dppl Our keyboard has a demo button which plays a synth-trumpet version of Livin La Vida Loca. It's the only sound it ever makes
@pwr2dppl Yeah, mathstodon.xyz
We've had a huge influx of people leaving twitter, so now's as good a time as any to give it another go
@SLSingh D. R. Kaprekarrefour
@ben_nuttall Because the generation that grew up reading Harry Potter are now in their 30s and kitting out their kitchens, so someone saw a buck to be made
@MathsTechnology @icecolbeveridge intriguingly, (-8)^0.333333333333333 works (15 3s), but (-8)^0.33333333333333 (14 3s) doesn't.
@MathsTechnology @icecolbeveridge and spot a pattern in this!
@icecolbeveridge @MathsTechnology 🤷♂️
