Unconscious bias (which is rubbish anyway) isn't unconscious if you know about it. So here goes... yet again. I've only watched about half an hour of gymnastics so far, but I've clocked "elegant, graceful, elegant and smooth, full of grace, etc." for white gymnasts and...

x.com/baystastic/sta… Excited to be giving a talk on how maths shapes our everyday lives at the British Science Festival! If you’re around, come join us for an insightful session👇 🎟️ bit.ly/45EnOQB Looking forward to seeing you there! #BSF24 #maths #stats #datascience

I have no doubt that @Benorlin's new book (Math for English Majors) will be excellent (as all his others have been), but it's a pity that Amazon don't render equations correctly in their blurb:

Session 2c will start with Tony Mann introducing a huge number called TREE(3), which has formerly appeared in a Numberphile episode Maybe he should make it appear in chalkdust's next issue! youtube.com/watch?v=3P6DWA…

We start this session with Tony Mann, who has recently learned about the remarkable number TREE(3), and shares his findings - enjoy these Numberphile videos: youtube.com/watch?v=3P6DWA… youtube.com/watch?v=IihcNa… 1/4

Tony Mann Next up, it's Elizabeth Brocklebank, who's been playing bingo using the Microsoft Authenticator app. Because why not? Next is Alex Bolton, who asks, how many points must be placed in the plane so that no collection of disjoint (non-overlapping) unit discs can cover them? 2/4

Tony Mann Alex Bolton Alex shows using a probabilistic method that 10 points can always be covered, and shares a set of 45 points that cannot be covered. For more, read this paper: 2012.cccg.ca/papers/paper13… 3/4

Tony Mann Alex Bolton Then we end with Mathsnetty, who advocates for a better narrative in probability puzzles: rather than it always being coloured sweets in bags, what other examples can we use? 4/4

Big MathsJam Tony Mann I really enjoyed Tony's talk! The kids often ask about TREE(3), and I didn't have a good explanation of it until now.

Once again I had a wonderful weekend at Big MathsJam, seeing old friends and making new ones. Lots of exciting and inspiring maths to think about! Huge thanks to Colin Wright and the MathsJam team for all their hard work which made it such an enjoyable event.

Flattered that a puzzle I've been giving students for some years has been posted here.
