Klein bottle

The Klein bottle is a surface invented by the mathematician Felix Klein: it was the first example of a surface that is both without a boundary and non-orientable. The latter property consists roughly in saying that the Klein bottle has no inside or outside. However, this object only exists in four-dimensional space, and any three-dimensional representation is incorrect in so far as the intersection of the bottle with itself is merely an effect of perspective.
