he could've saved a lot of time if he had said cube and asked you to figure out things for a cube or sphere rather than something i had to search the internet to find what it was

well a cube is easy to deal with, a parallelepiped is something different so it makes for a more interesting example of how to approaching a thing you aren't sure about. the book is called how to solve it, not h*w*l

thanks... nerd

it is written for a teaching perspective, like you're supposed to know what these things are already if i remember correctly

i'm really bad at higher level math and am trying every day to get better, but i run into these incredibly frustrating levels of abstraction or assumption on the reader constantly

well, there's never been a better time to try and get better at this stuff. it's maybe not super fun to have to stop and look a thing up on the internet, but we can and that's great. it's tough when you don't know what you don't know, and sometimes you have to go back and check out the fundamentals. what kinda math are you looking at?

monty hall also always reminds me of my other favorite non-intuitive probability question:

you meet a couple who tells you that they have two children, at least one of whom is a boy. assuming boys and girls are equally likely, what is the probability that the other child is also a boy?

1/3

1/3 boy
1/3 girl
1/3 doesn't subscribe to your gender binary

solution:

with no information, there are four options
1) girl/girl
2) girl/boy
3) boy/girl
4) boy/boy

since at least one child is a boy, option 1 is eliminated. there are now three remaining options, of which only one has both children being boys. the intuitive answer, 1/2, is true only if the couple specifies which child is a boy


oh neat

if 0.99999.... = an airplane on a treadmill transporting a helicopter on a turntable, and monty picks a door that has a blue-eyed person, who leaves the island that night if both prisoner A and prisoner B remain silent?

ok so dance is important for ~reasons~ but how geometry works on a sphere is just plain frivolous. let me just write this down.

more rear end-shaking in dance than in geometry

i hated the horrible reasonless memorization and it was boring

i have really benefited from teachers that go through proofs and derivations to show how everything works, and then it winds up all being connected and making sense *~WOW~*

also i am bad keeping everything memorized so knowing where a formula comes from helps me tease it out when i can't straight up remember it
