I hold the opinion that Richard Feynman was the best physics teacher of all times. I keep his three red volumes always at the main position of my bookshelves, aside Dirac's "Principles of Quantum Mechanics" and the Landau-Lifshitz collection. What is it that puts them in a class apart from every other introductory text? A Nobel-prize winner, Giaever, I think, said that he seldom had to reach for other book of physics than Feynman's. On the other hand, the very respected mathematician Gian Carlo Rota gave it a bad review, orienting students to go instead to Halliday-Resnick for help. Perhaps these opposite opinions give us a clue: Feynman's "Lectures" are the sole book to present basic physics as a living subject, as real physics, that thing that researchers slowly build in their day-to-day toil.For the author, as always, strived to rebuild everything almost from scratch, sometimes with great originality. This explains why we never grow tired of it. It explains too why it "lacks" the organization of a text designed solely by pedagogical purposes. It's an asset, rather than a liability. If you are a beginner, use both (Feynman and Halliday-Resnick). In Feynman you'll see the magic and understand the beauty of a career in physics, as in nowhere else.
