From Syd Curtis
Dean Ware makes the point that a piece of paper, being made of atoms, has
depth and is in fact a cuboid, topologically equivalent to a solid sphere. Thus,
it has only one side
(10 February, p 57). That side, however, may more logically
be considered a surface.
If we stick with sides, then semantically the piece of paper has eight sides:
outside (the surface), inside, left, right, top, bottom, front and back
sides.
