An immortal fumble by kk (aka Brian D. Jones, Cadwgan Gedrych, Martin Miller, Edward Travis, Ron Aikas, Roy Royce, John Reid, ...) (10-May-2006)

The mathematical proof revisited

A mere glance at the site shows that Dirk is simply wrong.

It is easy to see that a the following single picture can
show the entire experiment:
(Note: a clock reading zero is shown as [0].)

Primed Frame            x=1
E2                         E1
Unprimed Frame          x=1

Note that - just as was said - the unprimed frame's origin
clock reads zero as event E1 occurs at t = 0.6 and at x = 1.

All readings and distances are given per the relativistic
transformation equations.

Contrary to Dirk, there is no clock which reads two different
times at once.
