Once again I had a wonderful weekend at @BigMathsJam, 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.
Our final session of MathsJam 2024 begins with @Pecnut, who tried to compare packs of tomatoes in a Californian supermarket and got confused - in the US, pre-packed fresh veg can be sold by both mass and volume inconsistently, including the use of the perplexing "dry pint"!

And for our final MathsJam talk of 2024, it's @meredith_martyn, who wonders how many of the 2,200 passengers on the Titanic shared the same birthday? Was there one birthday which gave passengers increased survival odds? And most importantly, how many of them were called Sam?!

Huge thanks to everyone who was involved in making this year's MathsJam UK Gathering happen - we hope you had a great time, and we look forward to seeing people again next time! Safe travels home everyone!

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.…

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?

Starting the next session, @Andrew_Taylor shares some quirks of the way computers do arithmetic - including a value called "minus zero", and another that's not equal to itself. He looks at how and why compromising on the normal rules can actually make computers more useful...

Our next talk is from @Keke_Thom, sharing a series of Venn Diagram poems linked to a DARE art residency with Opera North, University of Leeds and the National Science and Media Museum.

Lastly, @IceColBeveridge has been playing the roguelike hyperbolic-space game HyperRogue, and has been stuck on the "Camelot" puzzle, in which the player needs to find a holy grail at the centre of a 28-cell circle. It's harder than it looks!
