Issac Asimov 's Understanding Physics is an extensive three volume survey of the subject but it is not s formal textbook. The copies that I have were published by George Allen and Unwin Ltd, London in 1966. It is, rather, an informal, even anecdotal inquiry into this central branch of science.

Physics for Entertainment by Yakov Perelman is a classic physics book. For me it was the first physics book that I laid my hands on. The one that I have was published by MIR Publishers, Moscow. Actually many editions of the book exist, varying in size and design. Its just the right book for introducing physics. Perelman is prolific writer when it comes to the extent of the topics he covers. The examples that he takes you can readily relate to, and they are presented in a way that almost anybody can understand. Diagrams from the book are fun. This I guess is the first science popularization book that has come out. Perelman has other gems to offer too. They include Mathematics for Entertainment Fun with Maths and Physics Astronomy for Entertainment and many others...
