- WJW 1y agoHow about things like Klein bottles that have no edges? (Although I guess that unlike a Mobius strip it's not possible to make a real one here on Earth so the quote from OP still holds)
- tines 1y agoYou can make it out of some other material that you can smooth, i.e. so that it doesn’t have edges.
- tines 1y agoCome to think of it, doesn't a sphere have only one side?
