Paulis exclusion principle hold only for FERMIONS that is paricles with half spin. For bosons there is no such exclusion principle and thus any number of particles can occupy the given state for BOSONS.
But for fermi particles, no two particles can occupy the same state with all the set of four quantum numbers (n, l, m and s) identicle.

The Scientist does not study nature because it is useful; he studies it because he delights in it, & he delights in it because it is beautiful. If nature were not beautiful, it would not be worth knowing, life would not be worth living. Ofcourse I do not here speak of that beauty that strikes the senses, the beauty of qualities & appearances; not that I undervalue such beauty, far from it, but it has nothing to do with science; I mean that profounder beauty which comes from the harmoniuos order of the parts, & which a pure intelligence can grasp. |
