Timothy S.: Well potential has become kinetic, but what of vector ??? Kenneth Udut* Ah - well the thing with vector is backdrop.* (frames, theater stage, spacetime, piece of paper) : Are you drawing on the paper, or is the paper moving around and the pencil standing still? [or there is something behind the paper that is causing the marks that has nothing to do with the pencil at all and the connection is just coincidental] So, vector, while useful, is somewhat of an illusion, considering a) there's no lines, not really b) well, that's really about it.
