Dr Christmas posted:Imagine telling them at the angles on the triangle don’t always add up to 180 degrees anymore. It's just an extremely simple edge case - 2-dimensional flat plane. We make these simplifications all the time with other things, too. Electrical engineers will tell you about the power triangle: S^2 = P^2 + Q^2 It's a fundamental relationship that's pervasive in power engineering around the globe. Except, it's not accurate except in the simplest of cases where is only one fundamental frequency, no harmonics, and perfect phase balance (i.e., something that never happens in real-world conditions). This can lead to 10 different residential power meters providing 10 wildly differing energy readouts for weird loads like LED lighting.

I remember doing incredibly bad during that part of 10th grade geometry because it wasn't enough to know how to get to the answer. We also had to write the name of the proof or theorem we used at each step of the problem and I already struggled remembering formulas now you're adding an additional layer of poo poo to remember on top of that? gently caress you Mr Yoder.

I took a stats class once and struggled to get a D, then I hit Quantitative Methods (stats with a fancy name) and she said "if you get a job running numbers in a lab you will never do any of this math. Here's hand-outs, you can bring a calculator and notes, and also every formula will be on the exam"

I think kids should be exposed to mathematics outside what's gonna be required of them because it forces you to think in different ways, but memorizing formulas is mostly useless. If you need them you'll memorize them from shear repetition.

I do math, and I don't remember anything that I don't frequently use. I do know where to look things up, though. That's a crucial skill.

Being able to memorize things isn't a useful skill in terms of job availability. A waiter who doesn't need to write down your order when it's a large table and there's multiple substitutions is still a waiter and doesn't have an easier time getting a better waiter job than the guy who has to write poo poo down but still gives good service.

They tend to be when you get to more advanced courses in college/grad school, but it's way more difficult to teach a group of kids deductive reasoning, conceptual thinking, and creative problem solving than it is to make them memorize a bunch of formulas.

when Lovecraft said 'non-euclidean' he meant impossible space kind of poo poo, like you walk across a room and go through a door and you end up back where you started at the other side of the room. Yes he used the wrong term but its loving obvious he didn't mean you should be scared of bendy lines you goddamn nerds

lovecraft used the phrase "non-euclidean" like less than five times total, the word he used for scary poo poo he didn't understand about ten times more often than that is "cyclopean" dunno why all the hangers-on latched on to non-euclidean though

Much of Lovecraft's work was done for magazines that paid by the word, and that explains a lot about his prose.

Hemingway's writing was done for magazines that paid by the word, too. Most American magazines, to this day, pay by the word.

Yeah, if I could bring back Lovecraft to life for like five minutes I'd spend four just terrorizing him with facts about famous black people, then the last just saying "Cyclopean just means made of stone blocks, non-Euclidean just means curves, and Chthonic just means subterranean."
