Pick up a copy of New Scientist this weekend, or go to the website (subscription or via your library), and you’ll find me writing about Snakes and Ladders and analysis of games of chance.

The next episode of the Mathematical Objects podcast, in which we chat to the lovely @nhoskee.bsky.social about what objects we consider mathematical, and why, is out now!: aperiodical.com/2026/01/math...

The Little Event was my 1st #SciComm Event back in 2016 when I still wasn't quite sure if it was for me. 10 years & 10 BIG Events later and I've carved out a place for myself in SciComm - including now as Chair of @big-stem-network.bsky.social! Where could #LittleEvent26 take you?

Another episode of our podcast is out today! Listen to me and @peterrowlett.net chatting about A Taxicab (in both of the ways you might possibly imagine): aperiodical.com/2026/01/math...

Very excited for Mystery Hunt this weekend!

Let's see if this will cheer you up - Valais Blacknose sheep in the snow. They're from the Valais region of Switzerland. Known for their unique appearance, they have contrasting black patches with a shaggy white coat. Both male & female sheep of this breed grow spiral-shaped horns. #sheep #cute

You're not ready for the name of the energy transition specialist at Heat Pump Association UK

Excited that the next Finite Group livestream will be @mscroggs.co.uk giving the behind-the-scenes scoop on his 2025 Advent Calendar. Will what I did to solve the puzzles match what he expected people would do? Attend live and get your scroggsvent questions answered! www.patreon.com/posts/upcomi...

Having fun planning the next few livestream events for our online community for maths fans - join the Finite Group, and you can watch interesting people chat maths one hour a month, and be part of our Discord community all year round! finitegroup.co.uk

Seriously though could you not have stretched to 26%

Merry Christmas! I’ve enjoyed the @mscroggs.co.uk puzzle advent calendar - prizes to be won if you complete the puzzles this year www.mscroggs.co.uk Something else I’ve enjoyed being part of: the Mathematically extra-complicated Secret Santa 2025 — @tomvii.bsky.social’s video: youtu.be/4pG8_bWpmaE

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!

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 🫦

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...
