Source sentences:
text: The electron and the proton have angular momentum, called "spin," that is a consequence of relativity.
text: In the quantum mechanical treatment, the electron in a ground state hydrogen atom has no angular momentum at all—illustrating how the "planetary orbit" differs from electron motion.
