### Rotations in Quantum Mechanics

Here is a summary of rotations in quantum mechanics from a first year graduate quantum mechanics course. This is a summary and will be most useful to those who already understand rotations.

### Topics in condensed matter physics

As a TA for an undergraduate course in condensed matter phyiscs, I made this review sheet for the second half of the quarter.

### Physics applets

Physics students often have difficulty getting intuition for quantum mechanics. Get a feel for 1-D quantum mechanics with this applet by Paul Falstad.
