Hello #maths fans! There is a competition starting today involving 16 mathematicians showcasing topics they think are interesting. Round 1 Match 1 is open until 0800BST (0700 UTC) tomorrow morning - take a look at https://aperiodical.com/2024/07/the-big-internet-math-off-2024-round-1-match-1/ and vote for your favourite!

I'm taking part in this but you'll need to wait until Friday to see my entry. But do check back in the days between now and then to see what others have to offer.

Good luck to the #BigMathOff competitors!
