Turning a sphere inside out!

kind of makes sense to me, but i mean visualizing something in 3d just makes my head hurt, especially when it's complex like that..
 
Unless you can pass normal materials seamlessly through another, no. But applied to fields of energy and magnetism, pretty cool.
 
I wonder if i ever could have learnt this without the visual representation. I can imagine it would have taken years to learn if you didn't have any illustration at all (straight number crunching). And now, 20 minutes, and you still get a bit annoyed by the overly pedagogic narration.

 
That was awesome. I feel like I understand the idea of it but there is no way I could explain it.

If you understood that fully you should become a mathematician. If you can manage your Aspergers haha.

the math behind it is pretty complex. i'm a math major going into my senior year of undergrad, and i don't understand a word of that wikipedia article.
it's a result from a branch of math called topology, which deals with surfaces and maps between them in different dimensions. pretty cool, but it requires a lot of background (that i don't have) to really grasp.
the videos are just a way to visualize the result. proving it is much more difficult, i would imagine.
 
the only sphere i turn inside out is one of these so i can jack off with it.i have a yellow one thats longer, kinda shaped like a catterpiller.

Sooooooo, it can theoretically happen but has absolutely no rational use, at least that I can think of. They basically just said "here is how you turn a sphere inside out, but you need this super sphere that cannot exist" Fuuuuuuuuu
