No problem. If I get nabbed, then I am taking you down with me since you mentioned it here as well. < bg >

Updated: Ooops, I guess I can't since you did capitalize it. :o

>Be careful with the word < censored >. Dupont will be after you. It is a trademark and should always be capitalized. You think they won't find it here on the UT, think again. A friend's wife got a letter from Dupont for a term paper she wrote. That was years ago, before the Internet. Ever since then, I've used the generic term, polystyrene.

>>To prove this to yourself, all you need are a bunch of evenly spaced spokes around a hub. You could do this with popsicle sticks in a < censored > ball. Now "roll" the sticks across a counter top. The tip of the stick in contact with the counter is the one that is motionless for an instant while the rest move. The "contact spoke" does not really move until the spoke ahead of it contacts the counter. Using the model you wrote about, I guess you could say change and the advancement of time does not occur until the next "point of contact" hits the counter, or "when the rubber hits the road". < bg >
