Guided Readings in Elementary Quantum Mechanics - Contains guided readings in Advanced Physical Chemistry and Theoretical Chemistry, specifically, Quantum Mechanics and Statistical Mechanics, with an emphasis on chemical applications. Notice that Guided Reading means what it says, you can not simply read the material contained in this site, you must answer questions about the material as you proceed. These notes constitute a general, non-calculus introductory physics course. Long and detailed. Particles, Special Relativity and Quantum Mechanics - Explains some of the more interesting results and predictions of modern physics.
All lecture notes are online, and include material on relativity and quantum theory.
Physics Tutorials - Math and some basic physics concepts requiring math or understanding of vectors. All topics can be downloaded as word files. Large file to download. Students - Geared towards teachers so they can in turn teach others about superconductivity. Detailed, and a good read for anyone interested in the topic.
