(September 30, 2013) Leonard Susskind presents an example of
rotational symmetry and derives the angular momentum operator as the
generator of this symmetry. He then discusses symmetry groups and
Lie algebras, and shows how these concepts require that magnetic
quantum numbers - i.e. spin - must have whole- or half-integer
values. Originally presented by the Stanford Continuing Studies
