Hi All,

I rescanned p114 (corrected typos), p115 and p 132a (scan was
not complete). I also added the summary of lecture 27 (p140a).

Thanks, Harry. This happens as a result of cut and paste. Now
the problems are all different.

hi jac,

you have two identical problems on the latest homework if i'm not mistaken

For example in the book of Itzykson and Zuber, you can find
a chapter on the quantization of constrained systems. If you
have questions please ask me.

I want to know if we can see how to construct Hamiltonians for the Schrödinger equation, how to introduce constraints to the QM Hamiltonians. Is there a Lagrange Multiplier method for QM Hamiltonians?

Dear All,

As many of you already noticed, in the first problem of
set 3 the $1/\lambda$ in front of the exponent should
be $1/\sqrt(\lambda).


Best, Jac

This question is about the historical and experimental relevance of h-bar. Basically, I am wondering how a constant that was originally used to explain blackbody radiation has anything to do with spin. Sakurai shows that there needs to be a constant relating K to p but only says this "turns out to be the same as the constant h-bar." Why? Then when we define the momentum operator, again h-bar seems to pop up without explanation. Why is "the" constant, the same as Planck's constant. Thanks. -Nick L.
