Hi, This might be an ignorant question but I have to ask it. The exclusion principle forbids particles from existing with the same quantum numbers, like, if you had 2 electrons, they have quantum numbers n, l, ml and ms, and one out of those 4 has to be different, right? What I was wondering was how close do two particles have to be before the exclusion principle starts working? obviously two electrons in different atoms can have all the same quantum numbers, but I ask this because I'm reading about quarks in baryons, and apparently they violate the principle, so how come they can get close enough to each other to be in the same particle? I get the feeling theres something huge here that I don't quite understand yet.
