I.e. what is *the* first dimension? To a Flatlander, there's no question which dimension is the third dimension. He already knows that there are two, but the one which is orthogonal to the ones that he knows about is clearly the third one. Wouldn't it be true that one can't differentiate between dimensions in which he can freely move? Scott Deerwester Purdue University Libraries
