@jessfraz welcome to mathstodon! In addition to MathJax, we have automatic TeX-to-unicode if you type macros outside delimiters, e.g. π ≈ ²²/₇

@pkra a big list of replacements copied from unicodeit.net. Here's the code: https://github.com/christianp/mastodon/blob/mathstodon/app/javascript/mastodon/features/compose/util/autolatex.js

@bmreiniger it's three because on a Fano plane each point lies on three lines. In the projective plane, there'd be as many colours as pictures on a single card (is it 7?)

@bmreiniger sorry, misread your post!

... and some more.

Doing some artistic thinking because I've got to fill a lot of picture frames in the department in a hurry.
Ignoring the colours, which ones do you like the most?
No image descriptions because these are all pretty abstract!

You'll like this puzzle that I made recently: https://www.thingiverse.com/thing:3856293
That axiomatization is an encapsulation of why the game Dobble (Spot-It in the USA) works.

Just published a new thing to thingiverse: the Seven Triples puzzle

This is how grownups move things around, right?

@pkra XSLT is a brilliant tool with awful syntax. It's worth knowing about, but so awkward to use.

@halcy I'm more surprised that cigarette vending machines are still legal!

There's some significant Weather hanging above Newcastle at the moment!

@kat you're right, non-negative k would do

Let \(a(1) = 1\).
Define \(a(n) = a(n-1) + n^k\), where \(k\) is the lowest positive integer such that \(a(n-1)+n^k\) has more decimal digits than \(a(n-1)\).

Is it always true that \(a(n)\) has \(n\) digits?

@jennytrustad yep, and I agree wholeheartedly

Hello dragons, thanks for inviting me today. I'm here to pitch my new range of sportswear for mathematicians, "Left As An Exercise".
I'm looking for £100k for a non-measurable subset of the business, which I believe we can double within a year.
