I wrote many physics notes over the years. These notes do not contain new discoveries, nor do I believe that I am any better at explaining things than professional physics educators. These are merely my personal study notes. That said, some may find them useful. These notes are not formal; although I try to make sure that the mathematics contained therein is correct, by no means do I attempt to prove every theorem, and yes, I admit I sometimes make leaps that would be unacceptable in more formal texts. The real purpose of these notes, then, is to provide an outline, a roadmap of sorts to help one truly understand what's happening, on the phenomenological level. Some of these notes, in fact, began their existence as comments in my somewhat eclectic Day Book.
