Double Maths First Thing is halfway through Ouch to 5k.
Hello! My name is Colin and I am a mathematician on a mission to spread the joy of doing maths. And this week, I’ve been doing some cool maths, looking at Oskar van Deventer’s Blocks puzzle and models of crowd movement.
I’m also half-following the British & Irish Lions rugby tour: I’m told by reliable sources that no pair of the 47 squad members share a birthday. What are the chances?!

Since pi approximation day is coming up next week, let’s start by looking at pi’s evil twin, the lemniscate constant.
KMB, via a comment on last week’s post pointed me at the fun-but-infuriating Intvania
Tom Mellor has sent me an equally infuriating set of mathematical dingbats. Enjoy/suffer!
Bob Bosch is doing, as usual, lovely things with knight’s tours.
And to round off a mathstodon-heavy link section (with more to come), here’s Fractal Kitty with some origami butterflies.

Not only is Tuesday Pi Approximation day, it’s also the traditional date for MathsJams around the world, including my corner of it; find your local Jam, or details on how to start one, here.
If you or someone you know has recently finished a great dissertation, and wants to write an article about it for Chalkdust (a magazine, I understand, for the mathematically curious), the IMA are offering a £100 prize to the best submission. Learn more here.
And if you’re interested in mathematical animation, the June TMiP Animation Challenge playlist is live. Read more about the challenge here.
That’s all I’ve got for this week. If you have friends and/or colleagues who would enjoy Double Maths First Thing, do send them the link to sign up — they’ll be very welcome here.
If you’ve missed the previous issues of DMFT or — somehow — this one, you can find the archive courtesy of my dear friends at the Aperiodical.
Meanwhile, if there’s something I should know about, you can find me on Mathstodon as @icecolbeveridge, or at my personal website. You can also just reply to this email if there’s something you want to tell me.
Until next time,
