Main Question or Discussion Point
Are Maxwell's equations thought to be exact? I realize this question is very open-ended and loosely-phrased.
lz, be careful.Yes they are. But keep in mind that each one of maxwell's equations inevitably contains some sort of fundamental constant (mu or epsilon usually; not to mention electric charge etc etc) which are measured quantities and therein not exact.
Well, if you take into account the masses of the apples, which is what is physically relevant when you buy apples, then you have less mass when the two apples are together, right ?
by the way, that'sEpsilon-not.
Mu-not is defined. At least, that's what my professor said.
I guess so :rofl:so, that applies, too, when two physicists get together?
They have gravitational biding energy, don't they ?Umm--what? Are you using special relativity?
