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...
