me, age 18: i will simply use math to understand all truth!

me learning about tarski's theorem: what da

for soe reason i spent my lunch hour making this out of the defunct "Matt Parker Speaks Binary Dot Com" source code and @christianp's logic:

Dr.-ed again, this time by a colleague rejecting an internal funding application, who should really know better.

So I'm really getting the full academic experience, without a tiresome PhD!

Prove that for every n, every polygon (even if it has holes) can be partitioned into n connected pieces of the same area

The "is this prime?" game ( recently passed 3 million attempts, which I might not have noticed if Siobhan Roberts hadn't written this lovely article about it:
I like how they embedded the game in the post!

Preparing a presentation on decolonising the curriculum for tomorrow.

I'm... not speaking from experience, let's say that.

Two gardeners had a duel:
Trial by combat.
Each chose their favourite tool:
Combat by trowel.

Thanks to everyone who's written something on so far.

I'm gathering ideas and some questions about how the site should be organised, at

I've made a change to LaTeX editing on unicode equivalents outside maths delimeters are no longer automatically inserted. Instead, when you select a LaTeX autocompletion, if it can be rendered using just unicode, that's inserted instead of the LaTeX code.

For example:
𝑓 : 𝑋→𝑌 = sin(θ²)
was produced by writing
\( f: X \to Y = \sin(\theta^2)
and pressing enter.

well, today I *was* going to add a nice feature to, but an hour later I can't get my mastodon environment to even connect to the database, so that's not happening

Why is there no mathematical italic small h in unicode? The rest of the alphabet is there! This is madness

Here's a question: is it OK to omit parentheses around the argument to a non-standard function?

Like, "sin x = sin(x)" and "log z = log(z)" are common, but what about "f x = f(x)"?

Does the function name need to be more than one letter?

"flop x = flop(x)"

Mathematicians: variables are named using Latin, Greek, Fraktur, Hebrew and Linear B letters in bold, italic, script, sans-serif and serif forms.

Also mathematicians: I need some brackets. Guess I'll use good ol' parentheses again! 😎
