[Phys-L] Re: "moving clock runs slower" (not)

----- Original Message -----
From: "John Denker" <jsd@AV8N.COM>

I know how to do the demonstration Rick describes, i.e. I know
how to calculate d(t)/d(tau) ... but I don't think it demonstrates
that the moving clock runs slower. We agree about the equation,
but we appear to disagree about the interpretation of the equation.

Is the twin who made the near-light-speed trip really younger when he
returns? If he is, didn't his clock HAVE to run slow (again relative to
that of his brother--since their clocks ran at the same speed just before
and just after his trip)? Something real has happened to create the
biological age difference!
