The Classical Limit of Quantum Mechanics
If the theory of quantum mechanics is correct, then when quantum mechanics is applied to big things, it
must give the results of classical mechanics.

In Physics 110 you learned about space and time in relativity. Now we turn to things like momentum
and energy in relativity.
Summary of quantum mechanics ideas
Spin
In general, a state | doesnt have a projection on the z axis. But the states |z+ and |z do have
such projections, and
the amplitude for | to have Lz = + /2 is z
