For this year's MathsJam UK Gathering, the early-bird cutoff is a number of tickets - the first 101 people to book will get a discount, so don't miss out! The Graph of Doom is already looking quite steep, and more than half the early-bird spaces are gone already...
A graph showing bookings for MathsJam 2026. The graph has a line for 'Attending' which goes up steeply from 0 at -160 days to just over 50 at -135 days, and a line for 'Remote' that's still fairly low. There is a faint diagonal line which the 'Attending' line is currently above.

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.
