[General] relativistic mass

[Adam K]

With the danger of producing the impression that I have only read one book,
Martin I thought you would enjoy this quote:

*The deflection of light rays that pass near the sun is not a purely
gravitational phenomenon, it is due to the fact that an electromagnetic
field possesses energy and momentum, hence also mass.*
