Renting vs. Buying This Textbook

Renting is usually cheapest if you only need the book for one term: you return it with a free prepaid label when the term ends. Buying used can beat renting when the sell-back price is high, so compare the sell-back price with the rental price before you decide. An eTextbook arrives instantly but usually expires. Rentals and used copies rarely include working access codes.

Always match the ISBN on your syllabus (9780195158335) before you order; different editions have different ISBNs.

About This Book

The book emphasizes physical appreciation of concepts through heuristic reasoning, metaphors, analogies, and creative explanations. Such an approach is different from a purely deductive technique that uses mere mathematical manipulation of symbols and ignores the physical meaning behind various derivations. This deprives a student of the enjoyable experience of logical uncovering of the subject matter. Here the author uses mathematics not so much to prove axiomatic theory as to support and enhance physical and intuitive understanding. Wherever possible, theoretical results are interpreted heuristically and are enhanced by carefully chosen examples and analogies.
