How does fractional spin effect the symmetry of combined wavefunctions?



Why is Planck constant the universal anchor for determining if a particle is a Boson or a Fermion?

          The relation between spin and the exclusion principle is called the spin statistics theorem, but I don't think there is an elementary explanation for it (other than doing the math).

            There is the elementary handwaving that exchanging two particles is half a rotation. At least in 3D, a full rotation gives the state that one started with, but in 2D one can have anyons (fractional quantum Hall effect).
