Arrived at #MathsJam on Friday to find my front door key tangled up in my keyring. Many mathematicians (>10) had a go at untangling it. No go.
Stupid o'clock Sunday morning, heading to check out as I had to miss the final day, I pull my keys from my back pocket. All untangled. #MathsJam trolling me.

Big #MathsJam -ers who took the train home today and are also movie fans might have recognised the railway station building from 1987's Superman IV.

Had a lovely weekend at @bigmathsjam.bsky.social getting lots of mathsy inspiration from all the best people, but I'd be lying if I said that I wasn't also glad to be going home to destimulate!! Thanks so much to Colin Katie, Scroggs and everyone else who helped for a brilliant time! #Mathsjam

Starting the penultimate session of #mathsjam 2025, Kristin Ohlmann showed us how the digits of pi and tau can be used to improve visibility of her unicycle. And she's actually brought it with her to MathsJam! Here's her Python code:
