Bored over the festive season? We're still seeking contributions to our ridiculous saytheprime.com video project: sign up and make a 5-minute video of yourself saying a chunk of digits of the largest known prime number. Can we finish before they discover a bigger one? It's a race against maths!

Looking for some nerdy drawing fun over the next few weeks? My Xmas & New Year zines are available to download for £1 (or more) and you’re welcome to print as many copies as you want! They’re A4 but I’m told can be printed on Letter paper & trimmed #SciArt ko-fi.com/hanaayoob/shop

Another Mathematical Objects podcast episode is out! Find out about the interesting maths behind a slice of pizza: aperiodical.com/2025/12/math...

New Mathematical Objects podcast episode: @steckl.es tells me about the maths behind a slice of pizza!

It's tonight! Who's joining us for a #scicommburrito in Manchester? scicommburrito.co.uk

Learned today that “Galápagos” comes from a Spanish word for tortoise, meaning that “Galápagos Tortoise” is, in fact, a tortology

I hate how much I enjoyed this BIG NERD DESIGN ENERGY 🫦

OMG have you seen Robin's new pin badges

I'll be giving the Liverpool Maths Society's Newstead Memorial Christmas Lecture, on 9th December where I'll be talking about fractals and the lovely maths behind them. Tickets are free here: www.eventbrite.co.uk/e/fractals-j...

In case you missed it, we've added a new activity to the 15minutemaths.com shop, which involves cellular automata and some relaxing and mindful colouring patterns. Check it out!

#64 is a power of two, so I am fortifying myself with the power of two post-donation snacks (obviously, Orange Club and ready salted Seabrooks, the best snacks). #GiveBlood #NHSBT

I had fun joining @peterrowlett.net and @steckl.es recently on their mathematical objects podcast, talking about my wood puzzle collection. Most of the time was spent struggling desperately to describe a highly visual topic in an audio-only context. open.spotify.com/episode/0rRM...

It's been a while, but over the summer we recorded another series of our podcast Mathematical Objects, and the first episode is out today! Find episode 1 here, or look for Mathematical Objects wherever you usually listen to podcasts: aperiodical.com/2025/11/math...

Oh no

I'll be speaking at Maths in Action on 26th November (and at the one on 10th December as well) - still spaces to book for A-level maths students who want a fun day out with some wonderful maths speakers! educationinaction.org.uk/study-day/ma...

Have spent an enjoyable hour wrestling with LaTeX/Beamer and now my slides have numbers how I want them to and everything I've been copying and pasting is now a \newcommand and I'm very happy

If you missed it last Thursday, I'm on Radio 4 again this evening at 8.30pm on Inside Science, chatting about the latest science news and how I can always manage to relate everything back to maths. You can listen on Sounds here, or live on the radio tonight: www.bbc.co.uk/sounds/play/...

In case you missed it: I'm part of the Finite Group, an unholy alliance of mathematicians with a free Discord community and monthly livestreams with great people about cool bits of maths. Our next livestream is 27th November and involves robots! Find out more and join at finitegroup.co.uk

Recently I was playing with the Square-Sums Puzzle (as explored previously by @standupmaths.bsky.social on Numberphile) and realised it would be fun for schools. So here is a FREE teacher resource: think-maths.co.uk/square-sums (and enjoy its use being modelled by my in-house mathematician below).

New maths resources alert! We now have a cellular automata activity on 15minutemaths.com, made by the lovely @alisonkiddle.bsky.social - grab yourself some printables, slides and session leader notes to run an interesting and mindful maths activity!

TLDR; The PSF has made the decision to put our community and our shared diversity, equity, and inclusion values ahead of seeking $1.5M in new revenue. Please read and share. pyfound.blogspot.com/2025/10/NSF-... 🧵

A reminder for UK residents

Salt and vinegar square and circular crisps, on a cheese topped bap (with a slice of salami, not visible) #CrispSandwichDay

Have been stocking up for #CrispSandwichDay tomorrow, and now have all three shapes of 2D crisps (Discos, Square Crisps and Doritos) as well as some Monster Munch (the most 3D crisp)

This will be a fab day! Maths Week England is a great excuse to do some maths in England - more info at mathsweekengland.co.uk

What a weird name for a dog. But sorry for their loss.

Thoroughly deserved recognition for nuSTEM, who have done fab work for many years. And a lovely bunch to boot.

Today's #hackjam successes: no actual machine knitting, but made a new handle for the knitting machine case as the plastic one had snapped, and also did a bit of crosswords, a bit of hand knitting and changed the batteries in the doorbell.

Excitingly, Today's the opening day of MathsWorld, the new hands-on maths museum in London. I've really enjoyed visiting MathsCity in Leeds, but they've now got a London location too! Details at mathsworld.com

Our show on the scientific secrets of games - and why we love to play them - is on @BBCRadio4 1630 today. With the brilliant @gillyforrester.bsky.social @steckl.es and #TheTraitorsUK ‘s Jazatha Christie himself - Jaz Singh. So much fun to make. Hope you enjoy! www.bbc.co.uk/programmes/m...

Earlier this summer I recorded a live episode of BBC Inside Science, chatting with a psychologist and a contestant from The Traitors about the science of games, and how mathematical thinking comes into it. The show's on Radio 4 from 4.30pm, or you can listen back here: www.bbc.co.uk/programmes/m...

Me [in a nail bar]: pint of nails, please

I'm looking forward to Inside Maths again! Maths enrichment day, 9 Feb 2026, for year 5 and their teachers, at the Ri, London. Featuring @robeastaway.bsky.social and Fran Watson, hands-on activity and puzzles. Feedback from last year: insidemaths.co.uk/feedback Book here: insidemaths.co.uk/booking

If anyone needs me I will be in the museum, lying down next to the bog bodies.

It's tonight! Who's joining us for a #scicommburrito in Tortilla Manchester Arndale from 6pm?

Me, looking at the listing for the #crispsandwichday mug: "Ooh look, it also comes in ready salted, cheese and onion, and salt and vinegar... and prawn cocktail!" shop.vole.wtf/en-gbp/produ...

Want to run a short fun maths activity with 10-14 year-olds, but not sure what to do? At 15minutemaths.com we've written up some of our fave 15-minute activities, with explanations, slides and printables, and a set of three is £2.50. There's Möbius Bands, binary numbers & mindfulness - more soon!

Amazing: due to github.com/python/cpyth..., once you've updated to Python 3.14, you can use the command πthon to run your code
