This little book (124 pages of main text) contains an absolute gold mine of information on thermodynamics. With a minimum amount of mathematics, this captivating field is extremely well summarized and presented in a most elegant prose. Very little space is devoted to historical background, resulting in a book that is dense with scientific detail. As with most such books, some parts are a bit tough going and may need to be read more than once (as I did) for the points presented to better sink in. The author is truly gifted in explaining potentially difficult concepts, rendering them lucid, well-described and even quite exciting. Many practical examples are presented to illustrate the application of many (what many would call) very abstract concepts. Because of the very technical quantitative nature of its contents, I believe that this charming book can best be enjoyed by serious science buffs, by university students who would like an excellent complement to their main thermodynamics texts, and by scientists who would like a refresher on a subject that they loved in university but may never have used since.
