Hi,

That would still be

T^2 = 1/(c^2 - v^2)

= 1/[(c+v)(c-v)]

as RobF suggested

but 1/(c+v)^2 = 1/(c^2 + 2cv + v^2) , which is different

All this looks like the transformation for relativistic time dilation, but not quite the same, as there seems to be a factor c^2 missing.

This book by Prof Cox could be required reading, especially for those doing long time exposures where time dilation could be a factor I'm going to order it now.

Are there photos of PBC?

Cheers
