Help @TweetsofCushing pick a maths book for his soon-to-be 14 cousin. Do there exist any books that teach you real maths, not just stories?

Like, Bellos and de Sautoy books are wonderful, but what about a book with theorems and proofs in it?

*du Sautoy, oops.

@suevanhattum @TweetsofCushing what's "Math Girls"? We're British, might be hard to get hold of

via @suevanhattum, "Math Girls" looks very interesting en.wikipedia.org/wiki/Math_Girls

@jjaron probably the latter

@standupmaths have you seen 2016 = 3³+4³+5³+6³+7³+8³+9³ yet? From Bob Lyons on the seqfan mailing list.

I've never seen such a straight banana!

I'm making a new year's resolution to eat more chocolate. Homing in on the stationary point of weight=f(chocolate) by bisection

The decimal digits of n appear n times in the decimal representation of n!.

This is good, but you can't filter by usage rights, which makes it difficult to use. Boo. twitter.com/monsoon0/statu…

The sky outside is an odd colour. Shades of William Gibson, "colour of a television tuned to a dead channel" etc.

@christianp all I can say is hooray for automatic colour correction. If I wasn't colourblind I'd describe it using words

@monsoon0 I've written a comment on their facebook page

@JanvierUK wordpress.com? Or if you want to do it by hand, github pages plus something like pancake.io

@monsoon0 they suggest I contact the IMU Archivist.

How do you feel about [k]_n as notation for "k modulo n"?

wow that's awful twitter.com/Tegglington/st…

@icecolbeveridge you might well ask!

@njj4 that may be where this particular person is coming from

@noneatnamesleft it's not normal trains though, so 3 minutes is reasonable

@monsoon0 I might ask the person involved why he thinks it's a good idea. It certainly doesn't look pretty!

just got the same bit of journal spam at both my uni address and my gmail. Wonder what could lead both to fall in the same database

@HilariousCow if you were doing it for someone else, they'd have to give you sick time. Not a waste!

One problem with writing worked solutions to lecturers' homework problems for a living is that I'm going to make rookie mistakes quite often

Like, we've got this huge bank of questions that nobody bothered to write answers to, so I've got to go and write explanations.

Inevitably, some of my explanations will contain some absolute howlers of fallacies or misunderstandings. My brain has a low melting point!

@helenarney @stecks @standupmaths imagine how the duvet could possibly end up outside the cover when you're done. QED!

@standupmaths there's no link to makeanddo4d.com on standupmaths.com that I can see! The book cover image links to itself

@standupmaths do you have a subroutine about VBA macros?

@aperfect bought it last time it was that price :)

Alphabetising my dvds. Very strong tendency towards the first third of the alphabet

@jamesgrime threw them all away when I moved in with my wife. Now everything we have fits in one bookshelf

Breakdowns by letter. Strong showings for B, M, T (helped by Band of Brothers, Modern Family and Tintin box sets)

Breakdowns by letter. Strong showings for B, M, T (helped by Band of Brothers, Modern Family and Tintin box sets)

WHY WOULDN'T YOU WRITE "Disc 2" ON DISC 2?!?!

@jamesgrime I've resisted alphabetising for years. It goes against every instinct. Mainly doing it as busywork on a rainy afternoon

Now: the sleeves for the DVD holder are numbered, and I just threw them in a pile. More sorting!

@evelynjlamb or by the 24th century, people have realised that "for he's a jolly good fellow" is the far superior song

Not long until @Christiansmas 30. What improbabilities will the people of the CP-celebrating world achieve this year?

@TheBardOfTysoe flattered, but looking at the replies it seems a couple of people have already solved it

Noticed a fact about oeis.org/A087192

Another nice way of writing 2016, from Simon Plouffe

Problem with writing number theory exercises: keep finding sequence to put in the OEIS

For example, this: oeis.org/A179195

Made a thing to explore a cool pattern found by Dan Asimov (among others) codepen.io/christianp/ful…

Suppose I asked you to find the inverse of an integer a, mod m. How would you do it? Some reasoning about the last digit?

@icecolbeveridge yes, turns out I've already written a worked solution doing exactly that, four years ago...

@jjaron when I was in 6th form I attended a cambridge open day where they showed off an Euler disc. I was like, "oiled disc?!"

@sxpmaths finding the intersection points is hard. Doing the integrals is easy.

It's a big deal. twitter.com/JanvierUK/stat…

@JanvierUK thanks!

I've updated my 30 second challenge game to let you change the time limit christianp.github.io/30secondchalle…

Put in order of who you would rather fight: 1 30-year-old, 2 15-year-olds, 3 10-year-olds, ..., 30 1-year-olds

If you filled in "4 7.5-year-olds" in the gap there, you lose the fight by default.

Not sure I agree. 10-year-olds are impressionable; I reckon I could turn at least a few of them to my side. twitter.com/robeastaway/st…

@icecolbeveridge those Terrible Twos, though!

no twitter.com/TweetsofCushin…

I had the idea for this game yesterday. Does it work? christianp.github.io/duopoly/

@ChrisHazell72 yes. Each end of your line butts against another line.

@icecolbeveridge @ChrisHazell72 I'll add a diagram

@peterrowlett @ChrisHazell72 @icecolbeveridge it needs to be in the same row

@peterrowlett @ChrisHazell72 @icecolbeveridge I was thinking of changing the wording to "if you draw a line between two existing lines"

@peterrowlett @ChrisHazell72 @icecolbeveridge yeah, was thinking of doing that too

@peterrowlett @ChrisHazell72 @icecolbeveridge I've added little protruding willies when lines connect. Better?

@SLSingh I feel like just this was a minor plot point in Good Omens. Or was it another comedy apocalypse novel?

@peterrowlett chuck in a couple of gradians too en.wikipedia.org/wiki/Gradian

Association of Train Operating Companies is called "ATOC", which I read as "A to C", i.e. where British trains tend to go instead of B.

ATOC, where you must change to a bus replacement service for your onward journey to B

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

@mathforge no, and don't have access to a mac, sorry!

@mathforge Ahh, I always forget which of that and textContent is the real one. Will fix I'm the morning.

@standupmaths thanks! If it gets too easy, try isthisprime.com/game/?difficul…

@MathsInspiratn thank you very kindly! I was wondering how I could fit in seeing Colin. Can I come to the first show?

@sxpmaths that's had me the last few times as well

@MathsInspiratn @ColinTheMathmo I meant outside the show, but another viewing of the jugglenaught is always welcome

@ajkiddle we're always happy to publish anything you write on @aperiodical. Will get a large-ish audience.

@CantabKitty @alexbellos whoops! Should work now. Amazingly, your the first of thousands to try it on IE.

@CantabKitty commiserations

@peterrowlett I will be talking about... basically the same thing!

@peterrowlett I've planned mine, just need to make some slides. Had an encouraging chat with @ColinTheMathmo today to set myself at ease

@for_the_winn yeah! I really want to change my login screen background. No .tar.gz is understandable-ish.

@peterrowlett it leads up to that, yes

@peterrowlett maybe continue this on the slack channel

@blathersmaths17 pretty well!

Have a gander at some stats isthisprime.com/game/record.php

@lazymarky good luck with that! Have you played the game? It starts showing numbers above 100 at around 20 score @icecolbeveridge

@StevenD1974 sort of,yes - three.onefouronefivenine.com

@KristianStill @mathsjem it makes me so happy to read that. Thank you!

@Calculord @MrDownin really? It shouldn't do. I wonder what I've done wrong.

@alexbellos I've collected some stats about the primes game - thought the list of final numbers would interest you isthisprime.com/game/record.php

@aPaulTaylor looks like it

@AdamCreen that's ridiculous

@icecolbeveridge OK, I don't know what a chess is. oeis.org/A083276

@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?

Opportunity missed: they haven't issued a 90p coin for the queen's birthday. Or, even more commemoratively, a £90 note.

Eugh, the @aperiodical news queue is so long, and I won't have time to do any posts this week.

The most important website of our time standerorsitter.com

@TweetsofCushing yes, that's why I said it was a missed opportunity. PS £1.40 can already be done in 3

I'm going to be in Pretoria, South Africa, for June's @MathsJam night. Who's up for a southern hemisphere jam? @Pyfagorass?

@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!

Finished half of my to-do list. As a reward, I'm going to spend some more trying to get Clever Hans to connect to eduroam

@robinhouston your ships thing is on metafilter! metafilter.com/158885/Interac…

Have I broken isthisprime.com/game on phones, or is mine just being rubbish?

@samholloway now that's weird, and not the problem I'm having

@samholloway ?!?! I don't understand this. On wifi or cell?

@samholloway phew!

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

If I've done things right, you can now add isthisprime.com/game/ to your phone's homescreen, just like an app!

@samholloway can you add it to your homescreen? (settings menu, then "Add to home screen")

Just tried to type "cd localhost" in a terminal. I have no idea why. What was I trying to do? Are my hands trying to usurp my brain, badly?

@robinhouston Oh, I made a mistake! I started from not-a-solution to end up at rest must be your solution. Oops

@robinhouston s/rest/what. Crikey, not doing well tonight.

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

@JDHamkins @NemoPublius @robinhouston I would say "an arithmetic sequence of three integers". Anyway, glad we're all on the same page now

How many of you know the convention that in men's tops, the label either goes on the back of the neck or at the bottom left?

@C_J_Smith time to talk about globally unique identifiers

Auth code suddenly stops working because of timestamp mismatch. Turns out when I suspended my laptop, the VM's clock stopped

@peterrowlett I only have knowledge of men's tops, and assume women's are as inconsistent as all other women's clothing

@peterrowlett you're the first (of ~10) person I've mentioned this to who recognised it. Weird!

@peterrowlett yeah, I assumed VirtualBox was providing a "hardware clock" that follows the real one

Yep, that's its intestine

@robeastaway on Saturday I had an awkward moment in B&Q because I'd forgotten the PIN for my new account, paying for a new bathroom!

A short poem about the programming language Ruby

@standupmaths I'm sure your publisher has an XML version of your book somewhere. That would look similar.

@stecks not impressive. Helen's grandma is 95 next month

@robeastaway I was within an hour's drive of Newcastle Wyoming once, and didn't visit. Still regret it, even if it had turned out rubbish

.@ben_nuttall @stecks so we can continue this arithmetic progression either way: does anyone have a grandma who'll be 85 or 105 this year?

@ben_nuttall @stecks mine was 84 in January - close, but no cigar! (no cigar being the secret to a long life)

@AdamCreen very interesting, since I'm having my summer holiday in Ireland this year

@AdamCreen that would be helpful!

Pretty hugely misleading diagram on @BBCNews. I assume this is percentage of votes released?

@Andrew_Taylor grey bit is a circle section proportionate to number of votes released, party's colour fills proportion of that

@Andrew_Taylor I don't know where the data's coming from. Do you?

I would love to know, in seats where leaflets claimed party X "can't win here", how often party X did in fact win there. @icecolbeveridge

This election's probably not a good one to look at that though, because so little has changed

@Andrew_Taylor yeah, I can't see a way of finding out. I see what you mean about the turnout, but a guess would be less misleading than this
