Dear Mike,

Thank you for your patience.

I've had a chance to read up on Zeno's Stadium Paradox, and I'm
comfortable with his ideas, as you've outlined them above. At no time
does any one body actually move faster than one position in a single
moment.

As far as the *relative* motions are concerned, I think I can address
that issue to everyone's satisfaction in a future posting to this
thread.
