"Ben, we're starting now" - his colleague in a recording for a @threadsandtangents.bsky.social music round🤣

@bigmathsjam.bsky.social is officially over! Many thanks to everyone who organised, contributed to it, maintained the Gather town remote space etc. #mathsjam #remoters 👏👏👏

Naturally Colin Wright is our last @bigmathsjam.bsky.social speaker. He's discussing geometric construction of the 17-gon, going much further than Euclid's equilateral triangle one seen on the CERN sculpture #mathsjam

Nancy Blachman of JR Math Festival found a guess the number magic trick...and a variant. She then made another variant with animal faces + colours no the numbers! She's also got an animal video to demonstrate the trick #mathsjam

Raphael Colman brought his #Haskell logo knitted jumper to @bigmathsjam.bsky.social, he even has a stitch diagram for making one, and wanted to write a program in Haskell for making said diagrams. #mathsjam

Barney Maunder-Taylor says a square-based pyramid is exactly twice the volume of a triangular-based one (same side length). He doesn't want the tedious trig approach to proving it though, he wants a more intuitive route. He'll try the usual proof by @geogebra.org instead #mathsjam

Vanessa Madu is seeking chains of consecutive semi-primes, e.g. (9, 10) is a short one. Can't do a chain longer than four, sadly. No worries about the text overwhelm, Vanessa! #mathsjam

A #mathsjam #origami winner earned the competition organiser's origami paper that's been in her cupboard for 35 years 🤣

Competition competition time, @mscroggs.co.uk understandably uses the term "meta winners" to refer to competition competition winners #mathsjam #competition #competitioncompetition

Ben Handley has a follow-up on Chalkduster Clare's Skittles talk. He's been running his own skittle sims! #datascience #mathsjam

@mikegeogebra.bsky.social if you're not sure on covalent bonds, go get my handler, it came up in her GCSE & A-Level Chemistry (she's joined remotely) #mathsjam

@mikegeogebra.bsky.social likes stellated icosahedrons. Turns out 3D printing the ideal magnetised modules for putting them together is not as easy as it looks. #mathsjam

Kristin Ohlmann apparently used to decorate her unicycle. More recently, she used python code to calculate the area of her unicycle wheel covered by her reflective rope #mathsjam

Martin Whitworth says passports are size A6.5 #mathsjam

My handler had a itinerary for our Geneva trip this summer too, Chalkduster Ashleigh! #mathsjam

@mscroggs.co.uk found your solutions to the partridge puzzle #mathsjam zenodo.org/records/1705... ...do you need my handler to help refactor your code?

Niall Cardin is looking into neural nets playing board games. Apparently AlphaGo's inner workings aren't that advanced... I hear loss functions! #mathsjam

Fredrik Motland Kirkemo seems to be wanting volunteers...looks like his trick will feature some clown cards (not to be confused with Clow Cards from Cardcaptors) #mathsjam

Wii party, Paul Taylor? You're making me wonder if my handler should look into one of the Super Mario Party Jamboree minigames next year! #mathsjam #WiiParty #SuperMarioPartyJamboree

Ally Stanley mentioned Ben from @threadsandtangents.bsky.social in his @bigmathsjam.bsky.social talk #mathsjam

Ally Stanley referenced @threadsandtangents.bsky.social regular, Ben Ashforth, in his @BigMathsJam talk #mathsjam

My handler will be talking about the metal sculpture we saw at CERN soon on @BigMathsJam, after Miles Gould & @zoelgriffiths.bsky.social #mathsjam

Woke up to find the kids squabbling over who gets to watch the @bigmathsjam.bsky.social stream on the Nintendo Switch today #mathsjam

@robeastaway.bsky.social showing 16th century engravings including some maths in their art, including, the magic square in the Melncholia, and another engraving with a sad-looking Pythagoras "because he's 2,000 years old" 🤣 #mathsjam

Simon Allen showed a 1902 math puzzle column. Apparently the weekly prize money at the time, half a guinea, is worth £75 in today's money #mathsjam

Bob Huxley...hang on...3D jigsaws? 🤯 #mathsjam

James aka AJP is introducing @bigmathsjam.bsky.social to wikisim.org #mathsjam

Nettie has a trick for differentiating inverse functions, she'll demonstrate for F(x)=2x^2...already started by writing its inverse in three different ways. #mathsjam

Did look like you had some Laplace transforms for those systems' differential equations in your talk, Gavan Fantom! There might even be one on your T-shirt! #mathsjam

Izzy Whistlecroft likes hand-made logic puzzles, e.g. Toketa, Pulze, World Puzzle Grand Prix (with a 3D Sudoku), GMPuzzles, Sudokuvania... #mathsjam #puzzles Has anyone told her about @chalkdustmag.bsky.social's hand-made crossnumber?

David Lyford-Tilley is introducing abductive reasoning: en.wikipedia.org/wiki/Abducti... #mathsjam #bigmathsjam

Tarim's top 3 laws of physics at @bigmathsjam.bsky.social: ⭐ Law of gravity ⭐Theory of relativity ⭐Law of conservation #mathsjam #bigmathsjam

My handler spotted the red stripy SET in your slide, John Read! #mathsjam #bigmathsjam

@steckl.es bring on the fridge magnets! #mathsjam #bigmathsjam

Anindya Sharma has two terms for folder structure - "starriness" (breadth of your folder structure") and "pathiness" (depth). I try to find a balance between the two for my files, but that's not always easy! #mathsjam #bigmathsjam

Sounds like @steckl.es will get to chuck Laurence O'Toole's penguin across the @BigMathsJam room! #mathsjam #bigmathsjam

Knight + king chesspiece = nightking says Philipp Reinhard. He sketches some patterns of this chesspiece making only knight or king hops across all the cells in a magic squaree, and the paths make pretty patterns #mathsjam #bigmathsjam

Jørn Hafver is collectively referring to🪨📜✂️ as "symbols" on @bigmathsjam.bsky.social. I've heard of them being called "weapons" before... #mathsjam #bigmathsjam #rockpaperscissors

Hexagonal polyominoes on @bigmathsjam.bsky.social! Trust Dave Budd to put them in a puzzle on @chalkdustmag.bsky.social's latest issue #bigmathsjam #mathsjam And his contribution to OEIS: oeis.org/A378169

And Berkson's Paradox: en.wikipedia.org/wiki/Berkson... #bigmathsjam #mathsjam

I spy hypothesis testing on @bigmathsjam.bsky.social! #bigmathsjam #mathsjam

The @bigmathsjam.bsky.social staff managed to fix the stream in time for Brigitte Stenhouse discussion of the two Nepali translations of a classic Sanskrit math text #bigmathsjam #mathsjam. Turns out both texts had contributions from both the husband & wife translators.

@robinhouston.mathstodon.xyz.ap.brid.gy is intersecting prisms to get new 3D shapes, starting by intersecting three square cuboids #mathsjam #bigmathsjam

Tiago Hirth is still wearing his signature red scarf in his @bigmathsjam.bsky.social talk today 🧣🃏 #mathsjam #bigmathsjam

Team #Remoters @bigmathsjam.bsky.social #Mathscots has grown! #BigMathsJam

🦂🚨🦂 New Chalkdust alert! 🦂🚨🦂 DNA origami, tracks and an interview with El Nombre feature in our AW25 issue! Plus all your favourite puzzles & columns. Read the entire new issue now at chalkdustmagazine.com

@marharstar.bsky.social attempting to settle a @threadsandtangents.bsky.social question by saying he wouldn't normally turn the #Monopoly board while playing it 🤣

Absolute no to that plan! And my old Mathsjam mate, @treacherousbuzz.bsky.social, is on the same side! (She comes up near the end of the long Daily Mail article) www.dailymail.co.uk/sciencetech/...
