Query: Physics

I have studied physics using several different text books. Without question this is the most down to earth, easy to understand, user-friendly text I have come across. This is one of the few text books I have used that is actually written FOR a student and not to impress experts in the subject, other text book authors should take lessons from this book. I completed physics in a class that depended heavily on self study, this book not only made it easy but it was also pretty decent reading, not just a compilation of physics formulas and derivations. Anyone wanting a physics book you can actually make sense of, in my opinion, you can do no better than this.
