Every so often I pick up a book that I wish I read 10 years ago. Feynman's Lectures on Physics and Van Hess's Thermodynamics are among these, as well as Polya's How To Solve It for those more mathematically inclined. These would have certainly saved me from much confusion during my college engineering curriculum, for they focus on teaching the material to the reader, as opposed to masking it in the equations of a textbook. Some lucky folks have the ability to glance at equations and immediately grasp their meaning; for the other 99.99% of us, an intuitive explanation replete with real-world analogies helps to bring the meaning to life.
With a presentation both unique and entertaining, Lewis Carroll Epstein's Thinking Physics has certainly claimed a rightful seat at the roundtable of wonderful didactic books. Every page poses a question that challenges the reader on his view of the physical world, and nearly every answer tears down the fallacies of his intuition. Socrates would have been proud of the format, with each new question expanding on concepts developed in earlier answers. One of the 1-star reviews mentioned a lack of organization. This criticism completely misses the point. It is NOT a textbook, so "obviously" it will lack some of the rigorous development of concepts and precise organization that you would expect in a physics text. It IS a popular physics book with lots of cartoony pictures that a kid in elementary school could both enjoy and understand. At the same time, the insights will help build anyone's physics intuition, regardless of age. I read this book when I was 30. I have since started going through problems in Kleppner and Kolenkow and some other more advanced texts, and I really think this book helped.
