Topology is extremely fascinating.
Also, why does everyone say that it hurts their head? Didn't hurt mine :|
Because not everyone is very good at moving 3D shapes in their minds.
Not everyone is very good at doing the same thing as others in their mind.
For example, I get 3D shapes very easily in my head and can picture them fairly well, normally.
But I am completely stuff at doing mathematical arithmetic in my head.
And I know people who are the complete opposite.
It's the same with people who get confused by physics. There's too many things for them to do in their head.
It's all very interesting, but I can't help but think that it seems slightly pointless, when it has no real-world version to it.
If it's not physically possible due to the need for things to pass through themselves, then what is the point in having the ability to turn a sphere inside out, so long as it's physical properties are custom-made by yourself?
