" ... The strangest and most subtle of the properties of spin has to do with what happens when you rotate these particles. If you take something with ordinary angular momentum, like a spinning molecule. and apply torques to it that rotate the direction of its axis through 360 degrees, at the end of the process, you're back to where you started: the wavefunction for the particle after a 360 degree rotation is mathematically identical to the wavefunction before the rotation. Do the same thing to an electron spin, though, and you don't end up back where you started-- the wavefunction of a spin after a 360 degree rotation is the negative of what you started with. You need to rotate through 720 degrees-- two full rotations of the spin axis-- before you return to the original state. ... "
