Objects in 2 dimensions
[QUOTE=LBloom;3758446]When it comes to dimensions, you have to think a little differently. When you hear of a two dimensional object you're probably thinking of a infinitely thin flat sheet of paper. It has no depth, just length and width.
More nitpicking: an infinitely thin flat piece of paper is also an idealism.In my mind it is 3- dimensional no matter how thin it is.
At no point does it become 2 dimensional except as a mathematical abstraction.
