Further evidence the tiny L-P is a mathematician, at bathtime last night:

* holding a bottle full of water *
"Can you put some water in the jug, please?"
* stands bottle upright in jug, spilling none *

Must learn to speak more precisely __to my 1 year old__

reading Latin like, "superbum? more like super bum amirite"

Choose a random graph with countably infinite vertices by flipping a coin to decide whether to include each edge. Or, construct a graph with binary numbers as vertices, with an edge \(x\)—\(y\) when \(x<y\) and the \(x\)th bit of \(y\) is one. Or, construct a graph on primes congruent to 1 mod 4, with an edge when one is a quadratic residue mod the other. They're all the same graph, the Rado graph (en.wikipedia.org/wiki/Rado_gra)! It has many other amazing properties. Now a Good Article on Wikipedia.

@JordiGH I think they're auto-spamming lots of people. The emails are usually worded in a way that makes it look like they're not specifically targetting Mastodon. I'd be surprised if a human with any kind of influence on the system ever sees your response,

I wrote a bit about a bisection of a triangle's area which, when I read it, made me lower the book and call it a rotten liar. (It wasn't lying.) The thing might be old hat to you, but it startled *me*.

(I have a follow-up post to it scheduled to post later today.)

@nebusj I enjoyed reading that, and I'm going to try it. Morley's theorem is bad voodoo, true.

Learning fixed points and stability might be the happiest moment of this course.
Soon everything’s going to chaos. Literally, chaos.

@autumnaterr yes, but it's strictly virtual: nice-calculator.glitch.me/
I've never had any luck with soldering seven segment displays. Maybe one day!

@autumnaterr I made my own calculator recently, so the way they work was on my mind

@autumnaterr and tonnes of people in offices or non-automated shops have a basic add-subtract-multiply-divide calculator hanging about

@autumnaterr well, casio scientific calculators are what almost everyone uses. The ones they use these days can compute all sorts of statistics and do some light algebra, but the input method is the same.
