Maths Week England happened a couple of weeks ago. I had put my name on the speaker directory, and sure enough a maths lead from a primary school in County Durham emailed me to ask if I could go in and do something for them.

Double Maths First Thing: Issue 3F
Double Maths First Thing needs to collect its tickets, don’t let it forget.
Hello! My name is Colin and I am a mathematician on a mission to spread the joy and delight of maths as far and wide as possible.
This week, I’m steeling myself up for a double whammy of a long train journey and trusting the computer shop to repair my power supply, both of which are enormously stressful.

I’m not on BlueSky (I lose enough time to mathstodon, thank you very much), but some of the prolific ex-Twitterers are still doing whatever you do on BlueSky these days. Andrew Stacey has collated what he thinks is a complete collection of Catriona Agg’s geometry puzzles. Catriona is a superstar. Andrew’s a good egg, too.
In the good place, Amapanda cracks her knuckles and finds the towns furthest from a Wetherspoons. The interesting thing for me is the discussion about “what does town mean?” and “what does furthest mean?”.
Modelling sport mathematically always seems fraught with problems – the difficulty with humans is that they get all emotional and don’t follow the model – but Gabel and Redner have found that they can model “essentiall all statistical features of basketball” with a random walk model. Cool!
Need a random number and don’t have a die to hand? Jon Bentley in Programming Pearls has some ways you can code something up, assuming you’re too good for random.random().
Finally, a puzzle game: Ain’t It Funny How The Knight Moves?, a challenge to visit every square on the board that isn’t attacked by a queen.
Currently
There may be a few tickets left for Big MathsJam in Milton Keynes this weekend (November 21-23) – online attendance is available and I’m pretty sure that if you like DMFT, you’ll love MathsJam.
I’ve not yet got my hands on a copy of the new Chalkdust magazine (I’ll put that right this weekend), but on Tuesday 25th their book club will be discussing Matt Parker’s Humble Pi.
You’ll want to submit anything for the next Carnival of Maths, hosted by Tom Briggs, via the Carnival submission page.
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,
C
Carnival of Maths #241
Welcome to the 241st Carnival of Mathematics, hosted here at the home of the Carnival, The Aperiodical. The Aperiodical is a shared blog written and curated by Katie Steckles (me), Christian Lawson-Perfect and Peter Rowlett, where we share interesting maths news and content, aimed at people who already know they like maths and would like to know more. The Carnival of Maths is administered by the Aperiodical, and if you’d like to host one on your own blog or see previous editions, you can visit the Carnival of Maths page.
Mathematical Objects: Parallelepiped with Ayliean MacDonald

Hidden in Plane Sight
This is a guest post by Elliott Baxby, a maths undergraduate student who wants to share an appreciation of geometrical proofs.
I remember the days well when I first learnt about loci and constructions – what a wonderful thing. Granted, I love doing them now; to be able to appreciate how Euclid developed his incredible proofs on geometry.
Mathematically Gifted
Between the three Aperiodical editors (myself, Christian Lawson-Perfect and Peter Rowlett), there’s a developing tradition of excellent mathematical gift-giving. This year, Christian has excelled himself by designing and creating a brilliant mathematical hoodie, which features a meme about an in-joke (and who can resist either a meme or an in-joke?)
Mathematical Objects: Spirograph
A conversation about mathematics inspired by a Spirograph set. Presented by Katie Steckles and Peter Rowlett.
