Sue,

I never expected to come across you here. By the way your book has been
sent. Good luck.

BTW, Dirk Van de moortel is some kind of psychotic that
thinks there are two posters on the n.g. himself and an imposter.
He even wagers with people they don't know their own Identity.
I think the bellhop paradox must have fried his brain.
I lucked out. He thinks I am Dennis McCarthy from USNO.

I don't mind being confused with Dennis but I doubt he wants
to be confused with me so you have my standard disclaimer
on Dennis' behalf.

I'd like to have some comments on this.

But I think the simple answer is that we can use special relativity as
long as no force fields are involved.

Any comments?

You use SR when there is significant motion in free-space
to cause Maxwell's time independent equations to exhibit
errors due to the finite speed of light. (PoR)
