@Dabbawal is the jesmond restaurant wheelchair accessible?

I have 2 bags of xbox games and dvds
Where's the best place in Newcastle to sell them? I'd rather not support Grainger Games' sketchy owners

@manutdjax I'm not feeling that charitable. Three big bags of other stuff just went to the charity shop

@Dabbawal thanks. Turns out my dad called to book anyway.

@vickytnz ooh, you got one. Where from?

@vickytnz cool. My gf wants to replace her laptop with a tablet, but a chromebook could also work

@Quendus @haggismaths but odd that it gets even "fit a quadratic through (1,1)" wrong

Scorpion Dagger is hilarious scorpiondagger.tumblr.com

@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

Wow, I don't miss downloading packages from sourceforge at all.

@standupmaths so a baby should live its first day as if it's its entire life?

So @TweetsofCushing is paying $50 to courier a cheque for $30 to UCSD because their graduate office only takes cash or cheques.

Which, for an office which has to deal with international students quite often, seems peculiar. Lucky his supervisor has a US bank account!

(Yes, I've suggested paying someone at UCSD $35 to walk over to the office with $30 cash)

A slow day at work, so I've set up a fabfile to automate @NclNumbas server tasks. It's pretty nice! fabfile.org

@madcaptenor we did have an abc channel for a short while a few years ago. It played endless terrible sitcom repeats.

@standupmaths Well done for making your MathsJam conference slides even more awkward than mine. OK if we just offer a zip file?

@standupmaths ... actually, never mind. I assumed the TIFFs were images to go in the slides, but they ARE the slides! #inception

@Moon0nASpoon hah! Where's that?

@standupmaths turns out Katie already had.

@bengoldacre is this just people in work, or all people?

@JanvierUK thanks! Did you get my text on your birthday?

Today, my birthday, my age is one less than the sum of the components of the DD/MM/YY date. Does anyone achieve equality on theirs?

Today's dress code MT @ChirurgeonsAppr: this flower is aptly named "Naked Hanging Men."

Cmder is a nice cmd.exe replacement for windows. bliker.github.io/cmder/

So far I'm the closest to being DD+M+YY years old on my birthday. There must be someone out there!

@hornmaths doiii

Even on my birthday, I can't find a new integer sequence. I'd've been offended if this wasn't already in, though: oeis.org/A131383

@DoctorLewney where did 46 come from?

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

Another @Christiansmas fact: this year, for the last time ever, I'm living up to my name since my age is a perfect number.

Oh, BOO. I'm never going to find a new sequence, am I? oeis.org/A000348 This one was the second article ever in J. Int. Sequences!

This URL describes itself in French …tteadressecomportecinquantesignes.com

Probably not my last @Christiansmas fact: (28!+1)/(28+1) has 28+1 digits and is prime.

This integer sequence won an award at #jmm14 and is also the shortest entry in the OEIS (I think) oeis.org/A235383

@ebuie no - the comments say Carmichael's theorem implies 8 and 144 are the only possible products

OH @TweetsofCushing: "Wow, it's independent of how big 1 is."

Newcastle @MathsJam is in a couple of hours. Charles Grey pub, 7pm, bring your thinkin' bits.

@encratica very nice!

Hey guys, @TweetsofCushing is so inbred his family tree is nonplanar.

@outofthenorm2 wow, you've got a proper board! Did you make it?

Finally, I have a sequence in the OEIS! oeis.org/A236322 - number of (potentially overlapping) occurrences of n in n^n. Big day for me

@evelynjlamb yeah, but it doesn't matter until n=99. I have a non-overlapping one proposed at oeis.org/draft/A236314

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

@evelynjlamb I tagged the sequence 'easy' at first because the algorithm is simple to write, but apparently computation takes time? #whoknew

Continued adventures in not finding a new integer sequence: oeis.org/A180039

I could tell myself I'm trying too hard, but the fact other people have put these in implies I'm not. oeis.org/A195835 #oeiswhacking

@icecolbeveridge I've moderated my position on that after my summer students pointed out how often \left( gets the size wrong

@ColinTheMathmo train joined a gang at its home station, but the following section of track is on the turf of a rival train gang?

@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

Good news, everyone! The first player wins Pentago: perfect-pentago.net/details.html#i…

I've got a new PC at work. It's called Tynemouth!

New keywords on the OEIS: "look" and "hear" mark sequences with good graphs or worth listening to, respectively. e.g. oeis.org/A007318

Friends, I took on the @aperiodical news queue and failed. The only new post you're getting is an integer sequence review tomorrow. Sorry.

@TweetsofCushing what is it?

@evelynjlamb yesss most definitely we should try to do this. Where will you be visiting?

@evelynjlamb btw, we did the last review over skype because Cushing's in San Diego for 6 months, so we could do this right now

@evelynjlamb Cambridge is a full day's travel from Newcastle. It's not far from London, so if I visit there we could meet...

literally just said the words "I got bored with it before you found out about it." It's true, I'm a massive hipster.

Script correctly recognises turtle is not a mathematician. Caption writer unclear on definition of "examine".

@TheJournalNews I've been saying hello to them every morning! I assumed they'd just fly back over.

@haggismaths ah yes, the islands which, along with the Inner Hebrides, make up the Auto Hebrides

@evelynjlamb unscrew your hard disk and run to someone with a disk enclosure to plug into their machine?

I think I might be this generation's Ramanujan. Did you know 10pi - sqrt(2) = 30 (to 3 d.p.)? CRAZY!

@debecca I meant 2dp... Maybe I'm not Ramanujan. It's 4sf though, isn't it?

@debecca round both sides to 2dp, and they're equal. Makes sense to me.

At my current rate of repayment my student loan will be paid off in about 400 years. Is this government prepared to keep me alive that long?

@stecks I reckon they're willing to keep some legally-responsible component of me alive in a jar for perpetuity

old insurer: "pay us £35 and we'll send your proof of no claims, but we'll only give you 4 years instead of 5, for cancelling early"

@evelynjlamb that's like the most mundane, annoying form of culture shock

@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?

@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

@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'?

@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

Why can't google resolve DOIs?

@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)

turns out I'm a trendsetter! We should all do four-day weeks, apparently theguardian.com/commentisfree/…

@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.

Interesting: a plane just dug a tunnel through a cloud. An inverse trail?

@GatesheadLibs @nclroblib apart from Quack Kerouac, no.

Waiting in a car park for my girlfriend and this guy decided to join me

Day 2: the cat is back!

Since I'm in a church against my will anyway, an idea: zero-knowledge protocol to allow querying prophecy without revealing what it says

@haggismaths you might have a rogue @TweetsofCushing at your mathsjam tomorrow. Please make him feel welcome!

@evelynjlamb I may or may not have written a javascript library called lissa.js just for the opportunity to say its name

So when's the post-ironic Quake 1 mod scene going to get going?

Just found this video on the @NCLMathsStats vimeo page: Prof Robin Johnson asks if the Angel of the North could fly vimeo.com/76605407

@WWMGT That link didn't quite work because of the space. Try henkxvisser.nl/Three%20square…

Happy ﬨ approximation day!

@numberphile I just made one: is this what you had in mind? jsfiddle.net/vRWG8/embedded…

Off to @MathsJam. Will anyone else be there? Do mathmos take summer holidays?

@evelynjlamb let dimensionsinfo.com help dimensionsinfo.com/egg-carton-dim… "because size matters"

My new favourite site: dimensionsinfo.com "because size matters"

Can you libel a black hole?

@andyjonescs no, there's just @MathsJam, and the mailing list which sends reminders before each meeting. Email newcastle@mathsjam.com

Delivery company again a paradox of precision: my package will be delivered between 12:24 and 13:24.

@fumbleweeds ooh, my girlfriend was just asking if we could play the sims!

@jamesgrime The Adventures of Young Alan Turing

I had no idea so many people felt this strongly about Benedict Cumberbatch.

@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

@jamesgrime I have not seen that review

@haggismaths ah yes, @TweetsofCushing said you weren't at mathsjam. Back to the fun maths coalface now?

Poppy the puppy is here! She is so beautiful and curly and good and we love her!

Zonked.

@sxpmaths what book is that?

@outofthenorm2 @stecks I fixed that on Tuesday!

@elinoroberts @jjsanderson that's more of a first-album title

OMG the puppy's toy is a dodecahedron. Six-coloured though. Does anyone have a five-coloured dodecahedral dog toy?

Dodecahedral dog toy update: it's already the subject of mathematical study! plus.google.com/u/0/+Christian…

Does anyone make a weather app that gives percentage probabilities of rain and confidence intervals?

Birthday present for my girlfriend: a ukulele so she can finally make use of her @helenarney songbook. It's a hit!

@katemath @LaMinda what would one of those look like, and what equipment would she have? Blackboard and oversized chalk to fit in her hand?

We're gonna need a bigger bowl.

@evelynjlamb well, Helen did. I was involved only in a support role

I just saw a bird of prey catch a tiny bird. The victim made pathetic noises as it was dangled about a foot above my head. #teamcarnivores

@Sara_Tindall Aww, oh dear!

This hexagonal daddy long legs loves his symmetry

@JanvierUK m&s do good ones

@semiBad I use w3totalcache, but made that decision about three years ago

Very pleasing.

@ColinTheMathmo I've just registered and paid!

@sxpmaths is that S the right way round?

I'm helping at this! MT @NCLScienceComic: Our free infographics workshop (age 14+) is on Saturday @ToonLibraries

@hughhunt Normandy has some of the weirdest pizzas I've ever eaten. I once had one with FOUR steak haché on top

Thompson's group F is currently not amenable arxiv.org/abs/1408.2188

@aperiodical @stecks is the auto-tweet still not working? I redid the connections

Come join me by the fire. #unnervinglylouchepuppy

@evelynjlamb I have the same thing with "amenable"

@robinhouston *shocked face*

Suppose I'd better tell twitter - I'm engaged! (hand belongs to my betrothed)

@ben_nuttall Ted's Montana Grill on Larimer St (next to Euclid Hall!) is very good

Cor, I've made a lot of birthday cards over the years flickr.com/photos/christi…

@JanvierUK thanks!

My favourite party trick that never works MT @numberphile: Wobbly table not a problem for mathematicians — youtu.be/OuF-WB7mD6k

@numberphile I'm not too great at applying the intermediate value theorem by eye

@numberphile +you normally want to apply it after everyone's sat down, which means they all need to shuffle round. Haven't watched the video

@numberphile well, I've watched it but with no sound because I'm at work. It *looks* good :)

The new version of knockout.js has custom elements. Here's one to do a tex input with @MathJax preview codepen.io/christianp/pen…

@Bishnavitch maybe: prions can't be killed by cooking, and thrive in the brain. Some think eating brains is what killed the neanderthals

@Bishnavitch (I assume you're eating human brains. Because otherwise you're totally fine)

@peterrowlett @stecks @aPaulTaylor there's an ongoing email discussion. I'm going to set up the redirect today

@peterrowlett @stecks @aPaulTaylor (turns out I'm not clever enough to set up the redirect and override wordpress's nonsense)

@C_J_Smith would you say this is the whole equation? checkmyworking.com/misc/makebigma…

@C_J_Smith supplementary beard-stroker question: which gives a lower bound for the date of burial, the equation or the quote?

Here's a new God's Number alternative: least complex set of instructions to perform a Hamiltonian cycle on a Rubik's cube

@helenarney @FitzMuseum_UK @whereiscampsite for all in tents, and porpoises?

@peterrowlett @stecks yerp

@evelynjlamb related is that AMS Notices cover with the deliberately-wrong 3/4/5 triangle made of pebbles

I am currently banned from using the AMS's mathematical imagery site?! ams.org/mathimagery/di…

@evelynjlamb finally found it! It wasn't the Notices, it was the College Mathematical Journal mathtourist.blogspot.co.uk/2009/02/ponder…

Here's a nice puzzle I thought up while in M&S: is there any base where "1248" is a power of 2?

Huge changes to the closest @MathsJam map with the addition of Taipei MathsJam mathsjam.com/closest-mathsj…

(if anyone wants to make a correct, spherical voronoi version of that map, please do!)

@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?

@evelynjlamb certain parties abused our free pads of paper policy and now each student gets issued one pad at the start of the year :(

@ben_nuttall all the names up to 2010 sound like things you should consult your doctor about before using

@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"

@ColinTheMathmo better medium: google+?

Formula for the perfect pizza cheese, non-nonsense edition: youtube.com/watch?v=AZOSTI…

@ruimvieira hah, that's great!

@eassessscotland did you pass on participant emails to your sponsors? Your registration form doesn't say you will

@standupmaths if you wanted a number around 3000, why not pick 3435? Or any of the other numbers on this page: mrob.com/pub/math/numbe…

Best part of waiting for a lift near a hospital: overhearing gnarly phone conversations as sick people walk past

SpringerLink still thinks my university is called "University of Newcastle upon Tyne". If you've already added value once, why add it again?

"No animals were harmed in the making of this site" in the footer of the site of a restaurant which serves meat.

@evelynjlamb it's the most useful list I've ever kept. Constantly referring to it.

Wow. Bold move to quote the film 'Network' in an advert selling furniture.

Legroom! Glorious, only-moderately-restricted legroom!

What are these mysterious bee images I see in the @aperiodical's media library. Could it be true? Is @outofthenorm2 finishing his bees post?

Instant embedding of videos in the new wordpress editor is the best thing.

@mike_geogebra is geogebra 5 the "official" latest geoebra? The main download page still gives you 4.4

@outofthenorm2 oh alright. Sorry, I'll let you get on.

@stecks I had gripes about the lack of links, and then I forgot all about it

Why did I just work out 17^2 = 16^2+16+17 instead of 17^2 = 10*17+10*7+7*7?

(It's true, I'm shaky on squares above 15^2)

@theoremoftheday thanks - I've updated a post with a link to your theorem of the day about it. Always handy!

@CCMathResources MathsJam isn't really a schools thing, so I don't think it's useful to use the hashtag for your links

@BrainyMisc @CCMathResources #mathsjam is related to @MathsJam, the monthly maths-in-a-pub meeting. Deliberately nothing to do with schools.

@lyd_w @MrGrahamPearce oh my god, our school motto of "Ewige Blumenkraft" suddenly makes a lot of sense!

@icecolbeveridge you'd have to inset a compass as well, wouldn't you?

@Bishnavitch wow, so it's finally gone through? Congratulations!

Worst. Shisen sho. Ever.

@evelynjlamb excellent explanation in "How to explain zero knowledge protocols to your children" pages.cs.wisc.edu/~mkowalcz/628.…

@peterrowlett @mathsarcade I just did the same thing but I didn't find the induction talk guy in time so none of the freshers knew about it!

@samholloway once, it meant "Let's meet at Costa".

@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…

@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.
