Tonight we welcome Sydney Weaver to Melbourne (in her awesome waistcoat!). Sydney Weaver is a world champion Rubik's cube speed solver. Here she is with Robert Webb sharing cube ideas.

We have a variety of mathscots tonight (Haggis, Harry and Tinkle provided by @haggismaths, RachelWright @[email protected] on Mastodon , Colin Wright (@[email protected])) plus geometry made by Robert Webb and a fun Maths Jam Shout provided by Ottawa MathsJam!

#sguquestions are you REALLY that excited about... Bombas socks? And do you have any interesting stories about the advertisers you reject?

Hello? Is this thing on?
