Thanks, Youngjin, another'thought provoker'! I recall the analagy of a mite on a ball of string. It moves in 2 dimensions - in 'a line', but to us seeing the mite, it moves around and round in 3 dimensions... ain't that so?
Exactly! We encounter such cases of "pseudo-dimensions" in our everyday life. For example, a railroad is practically a one-dimensional space (because a train can only move either forward or backward), even though it is technically three-dimensional.
