So far the only thing I know we will cover in 139B is pertibation theory. Do you know of any topics in this course that would help us prepare for next quarter? We spent a couple days on solving the PDE for the hydrogen problem and we went over a little bit about angular momentum a combinations of orbitals. (I've been talking to a few chemists about s,p,d,f orbitals and we talked about them in class, but I still feel a bit rusty.) Have we covered angular momentum matrices yet or will that be next quarter?
it would be cool to see why all the elements want to be like the noble gasses i.e. why a valence shell of 8 electrons is so wonderful, thus the nature of favorable chemical bonds ( something to do with lowering their energy, i suspect?).
might beyond the scope of the class and a 2 hour class, though.
I agree with Wilson. I'm having some trouble with #8 and #9 as well. Could we go over superposition of eigenstates tomorrow? Why was my earlier comment removed?
Yes, I agree. Time dependence with mixed states can get tricky when trying to solve analytically, even with our clever Dirac notation. I'm still pretty confused about the 1-d infinite number of delta functions problem. A tying together of sorts would be cool too.
Angular momentum (different operators), Lz eigenstates.

Yeah. Definitely the Lz eigenstates and how you get the matrix. I'm still lost about that.

ReplyDeleteLets go over #8 and #9 from HW9
