Thanks, that's a very useful resource, though I was looking for a list, analogous to a Table of Integrals.

Does anyone know where I can find a list of Christoffel Symbols for various metrics? Metrics of general forms, as well as famous ones like Schwarzschild and Robertson-Walker? Yes, I can calculate them all if I really need to, but it's pretty tedious.

Ah, that makes more sense. Thanks!

I think I understand your reasoning, but something still isn't adding up. I found another problem (with solution) in another test, as follows. An elephant on a cliff is attempting to pull up a bag of peanuts (M1) vertically with a constant force (F0). Squirrels are attempting to prevent him from...

Homework Statement This is not a homework problem, just a question from an old exam I'm looking at. You have an elephant (M1) hanging on a sling, connected by a string and two pulleys to a hanging bucket of water (M2). The string doesn't stretch, so if you pull down on either the elephant or...

So the selection rules in that table do not account for matrix elements vanishing? I was under the impression the selection rules were derived from the CG coefficients.

The transition in the n=2 state of Helium from 3P1 (m=0) to 3S1 (m=0) is forbidden. I know this, because I went to a lecture where a group measured the fine structure constant very precisely using this fact. However, as far as I can see, according to atomic selection rules (available here...
