Surely you're serious, Mr. Feynman
Richard Feynman's Lectures on Physics is probably the best introductory physics book, bar none. I have been reading the copy that I checked out from my local library, and the explanation is so much clearer than the book that we use in school. Feynman understands that physics is very easy when you know math (this is also where many pop-sci physics books go wrong). As Pythagoras said (well, kind-of), “Philosophy must be pursued in such a way that its inner secrets are reserved for learned men, trained in math.”
I guess my ultimate goal in learning physics is to understand all the stuff that's in SICM. Nothing more, nothing less. Guan != physicist.
