Etc.  Scott, don't you imagine this whole tempest-in-a-teapot is the old
confusion over "relativistic mass" versus "rest mass"?  Bondi probably
said that mass is conserved, meaning relativistic mass, which is just a
statement of conservation of energy less a factor of c squared.  Rest
mass isn't conserved.

To the original poster, it's all very easy to blame your problems on
the nasty, horrible, mediocre American university system.  Especially when
you're writing from Britain, where the universities are all gleaming
castles-on-a-hill, which are so well funded that they actually lure
American faculty away!!!  (Sorry to be mean, but motes in the eye and
all that)
