# isn't there a momentum term?
I'm pretty sure there is.

Please tell me the equation, I don't feel like digging through my books :)

# I'll have a quick dig
bloody uni...hang on...

# ah yes :)
E^2 = p^2c^2 + (mc^2)^2

# so E does equal mc squared
as long as the particle is weightless (like a photon) or perfectly still

# Aha
I'm doing a masters, so I'd be pretty upset if what they're teaching me is wrong ... e=mc squared is the rest energy of a particle, so therefore no momentum factor is in it. Momentum when it's moving, obviously. Yeah, therefore the p :-)

EDIT: e=mc^2 for a photon ; wouldn't that be zero?

# hooray
we were both right :)

I'm doing a master's in electrical engineering. :)

edit:
I think that's why they're trying to come up with quantum relativity

neither works in the other's domain

# Masters
in astrophysics for me :-)

# I know a lot more about quantum
than I do about relativity

# other way round for me
actually, the thing uni's taught me most profoundly is:

1) long-distance relationships do not work
2) take full advantage of student bar prices

# hehehe :)
I haven't learned either of those

of course the second isn't applicable...
