I have just started reading Brian Greenes "The Elegant Universe"
One part in particular I thought incorrect was his explanation of the time dilation effect in Relativity.
On page 38 he introduces the reader to a clock which consists of two mirrors facing each other.
A photon is then bounced between them in order to achieve the time intervals necessary.
A second, similar clock which is moving is then compared and the claim is made that the second clock is
recording a slower time because the timing photon has to travel further to complete its journey between
the plates.(Because it has to travel diagonally). Therefore Time has slowed down for the second clock.
He then adds a normal clock(rolex) to the moving photon clock and makes the astonishing claim that
the rolex mustslow down in order to avoid discrepancies between it and the photon clock.
I consider this to be wrong for several reasons and it does put me off reading the rest of the book.
Has anyone else read this book and what do they think?

If you're not supposed to ride faster than your guardian angel can fly then mine had better get a bloody SR-71.
