Amazing: due to github.com/python/cpyth..., once you've updated to Python 3.14, you can use the command πthon to run your code

Python 3.14 is released today. Happy πthon Day everyone!

I'm home from #TMiP25. Was great to catch up with a lot of old faces and meet many new faces. I'm very very tired, but not the most tired I've ever been after working on an event with @steckl.es (see 24hourmaths.com)

In the last few weeks, I made the first issue of my new puzzle zine, Puzzlebug. You can buy a printable PDF from ko-fi.com/s/9f1f1875c4 if you like puzzles.

MathsJam (UK) Gathering aka Big MathsJam is always an excellent event and well worth coming to if you've not been before.

If you're coming to TMiP, do this session then do the puzzle hunt that I've written quickly afterwards and you should just about get back in time for lunch

Printed this puzzle to do at #mathsjam yesterday. It's a great puzzle mathstodon.xyz/@OscarCunnin...

Having a clear out of some old computer equipment that's been cluttering up my place for a couple of decades. It's absolutely SPARCtastic. All free to a good home. r/vintagecomputing are all over it, but if any of my friends here want something then just ask.

I'm very glad that the Switch version of Final Fantasy 12 has a 4× speed mode

Happy π Approximation Day!

We are finally ready to announce that EMF 2026 will happen on July 16-19, 2026, at Eastnor Castle Deer Park, Herefordshire. Expect more updates soon as we start spinning up the organisation again.

The comma caterpillars in the garden have started turning into chrysalises.

Some comma caterpillars have made their home in our garden

Forgot to go buy all the newspapers this weekend to get all the wall charts but thankfully Tesco had one copy of Match of the Day magazine left

Happy new paper on arΧiv day to me! arxiv.org/abs/2506.20188

Time Mime with Jrimes Gimes.

I'm chatting maths and games with @jamesgrime.com next Wed 25th June 2-3pm BST. Sign up at finitegroup.co.uk#join Either join a paid tier to watch live or join for free & get the option to pay one-off for the recording. Either way gets you into our Discord chat community, a lovely place to be.

Excited that #SciCompInRust25 is starting in a couple of minutes!

I refined my talk for the Scientific Computing in #rust workshop today! It's a lot of fun, and covers the things that I think #science (🧪) can learn from #gamedev. My slides are public (with full speaker notes): docs.google.com/pres... But there's still space! Sign up at: scientificcomputing....#rust

Video of me making this animation: youtu.be/EtKy0XBwgyY #MathsAnimationTMiP

I made an animation of a visual proof of Pythagoras's theorem for #MathsAnimationTMiP (using LaTeX and TikZ). Video of how I made it coming very soon

If you're interested in #ScientificComputing and/or #RustLang, you should come to #SciCompInRust25 next week. It's taking place virtually and is free to attend. Timetable at scientificcomputing.rs/2025/timetable. Register at scientificcomputing.rs/2025/register.

Had a fun day playing noughts and crosses against MENACE at @aiatkings.bsky.social AI Festival today

Clopen Mic Night (a maths variety evening that I'm doing the tech for) is live on YouTube right now at www.youtube.com/watch?v=JVu2.... Watch along now, or watch the recording whenever you like.

Am I the first person to solve ophex 1 (www.andrewt.net/puzzles/ophex/)? #StecksConf

Me: Hello ticket machine. Two return tickets from Peterborough to Manchester please. Ticket machine: printing 1 of 12

Pro top: make repetitive tasks more interesting by recording them and uploading them to YouTube as speedruns youtu.be/OYRmo7d4Ddo

As promised, here's a video of how I made this animation youtu.be/EctOgaLqGnw #MathsAnimationTMiP

I made an animation of a cube folding from a net for #MathsAnimationTMiP. Video of me making this using TikZ coming once I've had time to edit it.

I've been writing a website widget thing that we're now using to display puzzles on the Chalkdust website (eg chalkdustmagazine.com/regulars/cry...). If you're trying to solve one of these puzzles and it doesn't behave as expected, send me a bug report at github.com/mscroggs/cro....

I think Issue 21 is up there with the best issues of Chalkdust (and that's not just because I wrote an article for it)

Finally got round to uploading a video of my #BigMathsJam talk from last year. In the talk, I showed off the databet: my collection of 26 data sets that resemble the alphabet. www.youtube.com/watch?v=9bxG...

Happy τ-ϕ Approximation Day!

Exciting news: Chalkdust issue 21 is coming on 17 March! chalkdustmagazine.co...

Great to see these Animation Generation Collaboration videos start coming in! Find out more about the collaboration at www.talkingmathsinpublic.uk/animation/ #MathsAnimationTMiP

I made an animation of a point on a circle tracing out a sine wave for #MathsAnimationTMiP youtu.be/UW8m1nZ0lK4

Happy #worldbookday to an incredibly niche group of people, specifically @mscroggs.co.uk

Really hope someone somewhere has sent their kids to school dressed up as a Springer graduate text for #WorldBookDay

Project ideas I have no time for #385: Make a YouTube video of me and someone else performing the example screenplay from the Wikipedia screenplay article (en.wikipedia.org/wiki/Screenp...)

The pre-recorded voice at Cambridge Station just said "because a tractor has broken down on a level crossing". Is there any eventuality that they didn't record a voice clip for?

If my #mathsfest2025 talk goes wrong, it's because Matt made me stare at this for 2 minutes instead of getting ready
