That's better: now the symbols don't look like the ghosts of overfull hboxes

Omg it draws TeX! #plotter

Today I have had a lovely time writing a Numbas extension for graph theory.

The 3-year-old asked for a rainbow heart.

Took a moment with the #plotter!

I think I got my #plotter to draw a rainbow!

A few days into #plotter fiddling, this is the first thing that has really made me go wow!

Excuse me for reading the first paragraph and assuming the investment in the north would be on the same order of magnitude as the one in the south

This is simultaneously objectively rubbish and subjectively lovely.

My 3-year-old would like to know what winter looks like around the world. Could you reply with a photo of what it looks like near you at the moment?

Here's what it looks like near us, in North-East England.

What's this a drawing of?

Is it just me or is this graph sad?

oeiswhack: enter a short, meaningful, sequence of integers into oeis.org, returning no results.

I think this is probably the best oeiswhack I'm ever going to get

I have a #puzzle in the current issue of New Scientist, thanks to Rob Eastaway for xoming up with clearer wording.
(Though that didn't stop my dad from getting it wrong and insisting that the puzzle was incorrect instead of his solution)

Paternity leave over. Yikes!

While the baby is sleeping, I'm having fun working through the Lean natural numbers game https://wwwf.imperial.ac.uk/~buzzard/xena/natural_number_game/ #math

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!

Chillies! Grown outside! In the North of England!#SpicyMiracle
