It is a quantum mechanical property that distinguishes particles. Particles with half-integer fernification obey a particular kind of collective behavior called Fermi-Dirac statistics; particles with integer fernification obey a different kind of collective behavior called Bose-Einstein statistics. Both are completely different than anything observed in the ordinary world. It so happens that the transformation properties of fernification bear a resemblance to the same mathematical rules that govern the transformation of angular momentum, and so rather than calling it fernification, the word "spin" was lifted, although it means something completely different than rotation.

One. Yes, though it can only be measured if energy degeneracy is removed by the application, say, of a magnetic field, which determines a direction. > > Mitch Raemsch

Spin is defined as a steady rotation with a chaning size of radius. Such is the ice skater pulling in her arms. How is the spin oriented? Does it have infinite degrees of freedom and rotational speeds? Mitch Raemsch

It is not spinning. Quantum mechanical "spin" is just a word that has been borrowed. A much better term would "funnifulation" so what you don't think it means something it doesn't. > Spin is defined as a steady rotation with a chaning size of radius. > Such is the ice skater pulling in her arms. No, there are more definitions of spin than that.
