I made a guest post at the n-Category Café, thanks to a kind invitation by John Baez! The plan is for it to be the first of a series:

I miss mathematics

Imagine if all numbers were only 1 digit long. Like they all had a unique digit so they'd be a lot shorter but you'd have to memorize a billion unique symbols.

@seldo you mean this? 😜

There! This is a 'proper' Delaunay Triangulation and Voronoi Diagram. I did mess up in a few places with the lines for the Voronoi part though, I was still freehanding it and not using pencil guidelines XD

Before I colour it, here's a thing :D #MastoArt

Had some paint left over this morning so did another little nebula, then this around it :D

On 220gm watercolour paper measuring 148x210mm. If you want to adopt it, \$25 USD which includes worldwide postage, for the signed original :)

I like Zeno's paradox because it could have gone either of two ways. Either you invent calculus and oh hey we can add infinite numbers of infinitely tiny things, or you invent the theory of atoms en.wikipedia.org/wiki/Atomism and end up with Minkowski's theorem en.wikipedia.org/wiki/Minkowsk thereby opening up algebraic geometry.

Hello, mathstodon! I am a master's student in mathematics finishing up this December. I like discrete math (particularly graph theory) and algebra. Hoping to teach college level and beyond - assuming I pick up the Ph.D later. Nice to meet you all.

Here's a fun TIL: Because the ratio of terms in the Fibonacci sequence approaches phi, and because phi is close to the ratio of km to miles, you can approximate conversion between distances with adjacent Fibonacci numbers.

So 2 km ≈ 1 mile, 3 km ≈ 2 miles, 5 km ≈ 3 miles, 8 km ≈ 5 miles, 13 km ≈ 8 miles, etc, etc

A Mastodon instance for maths people. The kind of people who make $\pi z^2 \times a$ jokes.
