Electron spin is an intrinsic form of, for 10 points, what rotational physical parameter defined in vector form as r cross p.
One variety is calculated as the square root of the azimuthal quantum number times the quantity azimuthal quantum number plus one times h bar squared. Its total variety's z component is important in the Zeeman Effect, and it is quantized in units of n times h bar. Classically, it explains why neutron stars often rotate rapidly as they condense. Its time derivative is torque, which explains why this quantity is conserved when the net torque acting on a system is zero.
