>w-what do you mean you can just push it through to the other side?! that's cheating! uuuhhh... t-the theoretical material that I made up for this can't be bent too far, or it will be destroyed! yeah that's right!

Why does this make me so enraged

this math is for mathematicians not faggots 4chaners stick with calculus and high school algebra

The YT algorithm has showed me this video twice in my lifetime. Once when I was doing my bachelor's, and during the pandemic. It's always interesting to watch.

I'm with you, OP. The third movement in that GIF the two materials phase through each other. You might as well create a movement where they automatically go through each other.

The real world use for this math simply hasnt been invented yet.
Many such cases

The full video is much longer. My kid was super keen on it when he was two; used to watch it often. It was blurry as hell, like ancient public television. Seems they've released a sharp version since then:

I'm not a mathematician; the rules seem arbitrary to me, too. The material can pass through itself, but not kink. There's probably a reason this makes the problem valid and interesting, but I don't know it.

It's only weird because you're probably a pleb who only works with two-dimensional matrices.

This is math for people in first year of gradschool, would hardly call them "mathematicians".
