I was on More or Less this week with @timharford.ft.com talking about primes and the strange but beautiful Ulam Spiral www.bbc.co.uk/sounds/play/...

An Ulam Spiral is made by writing whole numbers in a spiral and shading the prime numbers.

Someone (or specifically Yves Chamberland) has made this lovely piece of music called "Squaring the Circle" with a bit of my voice in it. I love that sort of thing. And here is it www.youtube.com/watch?v=tOMZ...

Tom Lehrer RIP. I went through a big Tom Lehrer phase at one point. And him being a mathematician was just incidental, but also fun. What shall I share on the event of his passing? One of his satirical songs? One of his maths songs? Nah, I'll share this with everybody www.youtube.com/watch?v=2t7p...

Back in the dark days of 2020, me and some other maths YouTube people did a MegaFavNumber project where we asked people to make a video about their favourite number over 1 million. We had 277 entries and this guy has watched them all and made a video about it youtu.be/5YiD0wjEWeo?...

I watched all 270 #MegaFavNumbers videos so you don’t have to

Do you have a spare 3-4 minutes to be part of a daft online thing? We're collecting YouTube videos of people saying chunks of digits of the recently discovered Mersenne prime - and we'll keep going until we've got them all (or they find another one). Find out more at saytheprime.com

Say the Prime

We're attempting to get a collection of humans to say every digit of the newly-discovered (and currently largest-known prime number) Mersenne prime M136279841, and hope to achieve this before another…

What an event. We had 700 y12/y13 students batting around giant inflatable dice for legitimate mathematical reasons. I loved it.

Hello. It's James Grime. In exile from the other place because, unlike the harmonic series, I have my limits.
