We're stepping off Twitter - it's been fun, but it's no longer a viable forum to remind people about our maths meetups.

Keep in touch & keep mathing on!

The tenth month is October, but you wouldn't guess it by the name...
For more number-related controversy, puzzles and general fun with maths in the pub, come to Christchurch MathsJam.
We'll be meeting from 7pm this Tues 15th, at our usual spot in the Craft Embassy. See ya there!

Here's the challenge mode for all you math whizzes. Sample three numbers x, y, z uniformly at random in [0, 1], and compute (xy)^z. What distribution describes this result?

Answer: It's uniform!

I know how to prove it, but haven't yet found the "aha" style explanation where it feels expected or visualizable. If any of you have one, please send it my way and I'll strongly consider making a video on it.

h/t @alonamit for this one.

A Möbius strip walks into a bar, looking dejected. The bartender asks "what's wrong?" and the Möbius strip wails "where do I even BEGIN?"

Here's a math problem that I came up with during work on my newest math popularizing article.

Of course it can be solved mathematically, but you can also treat it as a coding challenge. Have fun!

A pirate walks into a pub with his bird screeching "Pieces of nine!"
He shrugs and explains: "Yarr, it's a parroty error."

My daughter had a nice problem in her high-school math club. Suppose you have 1000 white points and 1000 black points in the plane, no three collinear. Can you draw segments connecting them in pairs, from white to black, using each point just once, without any edges crossing?

A joke from one of our 'Jammers: if the only even prime is two, then what's all this monkey business about prime-eights? 🙈🙉🙊
