LMS Women in Mathematics Day

The London Mathematical Society has announced that this year’s Women In Mathematics Day will take place on April the 18th and 19th at the Isaac Newton Institute in Cambridge. It’s free for students and £5 on the door for everyone else.

The event provides an opportunity to meet and talk with women who are active and successful in mathematics. While this is an occasion particularly for women active in mathematics to get together, men are certainly not excluded from this event.

The deadline for poster and talk submissions is March 15th 2013 (contact Beatrice Pelloni); if you’d like to register as a delegate, get in touch with Katy Henderson by April 1st 2013.

The perfect formula for mathsiness

It’s mid-January, which means it’s time for the tabloids to trot out their annual “this is the most miserable day of the whole year!” story — before they spend the rest of the year blaming immigration, youth and political correctness for problems they’ve spent the last year stoking up.


What I did on my holidays, by Colin (aged 35 and a bit)

We’re all back from the big MathsJam weekend. We’ve got loads of material which we’ll start putting up once we’ve recovered our energies. Meanwhile, Colin Beveridge has sent in his report of the event.

Last weekend – as I’m sure all Aperiodical readers know – was the MathsJam annual gathering in Cheshire.

Now, I’ve always hated conferences. Loathed the bloody things. I resented travelling to them, resented preparing talks, resented the uncomfortable beds, the politics, the enforced niceness. I resented the nod-along-and-pretend-you-understand, the gabble-away-with-your-head-down-so-you-can-say-you-gave-a-talk, the questions-for-the-sake-of-advancing-pet-theories, the sessions that lasted weeks. I resented the trying-to-find-veggie-food-in-New-Orleans, the being-expected-to-show-up-for-everything, the having-to-keep-receipts, all of it.

I could have just stayed at my desk and played Tetris. But MathsJam is different.

The Super Subtraction Feat


How I Unofficially Broke The World Record That Never Was

One of the 70-digit subtraction sums I did for training purposes.

In April, a gentleman called B. Sai Kiran became, briefly, internet-famous for doing arithmetic. In Hyderabad, he subtracted a 70-digit number from another in the barest smidgen over a minute – 60.05 seconds, at the second attempt.
