Is this a nephroid?

I've made a clock which runs through every permutation of a deck of cards, swapping one pair every second.
It's not very useful.

mathstodon.xyz now has a live preview and completion of LaTeX!
This has been on my to-do list for a long time. You no longer need to worry if LaTeX will display properly or not.

This is pretty dire, from a closed-access journal: these matrices are typeset using \array{cc} environments, but they just used a horizontal space instead of a column separator, so nothing is aligned.
Value added!

I'm sure this must already be a thing, but I can't come up with the right google words to find it, so I've made my own:
A tool to take a subtitles file and a video and make a page showing the transcript alongside the video itself.

At the moment it just copes with Vimeo, because that's where the two videos I want it for are hosted.
Here's one of them: http://www.numbas.org.uk/talks/numbas-training-2020-07-15/

I have a load of EAMS talks on YouTube, so I'll support that next

I've seen some combinatorial underestimates on packaging before, but this one looks particularly low.
#TheyDidntDoTheMath

That's nowhere near an accurate transcription of this video but now I've got the opening lyrics for my new album

Not a single place name on this map sounds real.

My 'mathematicians for change' and 'mathematicians for inclusion' stickers have finally arrived!

If you feel like you need to make a visual statement of (1) your beliefs and (2) your mega-nerdity, Kate Poirier's brilliant "Math for equality" badges and shirts are just the thing: https://www.zazzle.co.uk/store/mathforequality
They're expensive but that's because the proceeds go to https://www.beammath.org/

Google Maps has sent me my "April timeline update".

Alright @mscroggs and @Pecnut, which one of you broke into my house?

Spent too long making this

You, a coward: Python doesn't have a switch statement

Me, a modern-day Galileo:

tfw a pure mathematician tries to write a motivational message

I've made an absolutely huge memory game (https://absolutely-huge-memory.glitch.me).
It wasn't straightforward to implement; here's a little explanation of how it works

yesssss

Couldn't do anything else, so made a wobbly clock

Back on my animations nonsense.
The toddler came to look:

"You doing maths, daddy?"
"I like that maths!
"How is that maths?"
