There are models I've come across in physics involving things such as a 4 dimensional surface of a 5 dimensional sphere. The reasons for that are not important, but it has always given me pause.
I can imagine such things readily enough, but I am stuck on one small thing: Is the surface of (say) a 3 dimensional sphere really only 2 dimensions? Even if an [infinitely thin] surface, can it really be 2 dimensions if bent through out 3 dimensional space?
