Having covered electron spin in the previous episode, now turn to orbital angular momentum. Again, a phenomenon familiar in classical physics relating to planets has an analogue in the quantum domain (although with profound differences). This leads to a discussion of permanent magnets, which Professor Carlson calls “a piece of quantum physics that you can hold in your hand.”
