Lewis Carroll Epstein explains deep ideas in physics in an easy-to-understand way. Thinking Physics is a perfect beginner's guide to an amazingly wide range of physics-related questions. The book targets topics that science teachers and students spend time wondering about, like wing lift. Epstein elucidates the familiar but misunderstood — such as how tides work — along with more obscure but fascinating phenomena like the "Bernoulli sub" and the "artificial aurora" created by hydrogen bombs. Broken into many short sections and peppered with Epstein's own playful hand-drawn illustrations, the book does not simply give the right answer: It also goes into the answers that seem right but are wrong and shows why they are wrong — a rarity in science books. Thinking Physics is a rigorously correct, lighthearted, and cleverly designed Q and A book for physicists of all ages.

It's a little bit like The Little Schemer in that it often asks you a question and expects you to try to answer it before turning the page (or turning it upside down). The problems tend to go like "if you did this, would that (A) increase (B) decrease (C) stay the same" or "(A) increase by one (B) double (C) quadruple" -- to minimize technical machinery while still engaging you with genuine problems, not vague analogies.
The same author has a book on relativity which looked very good from the first couple of chapters I read.
