The book was enjoyable and covered the first and second law of Thermodynamics in an easily accessible manner. I especially like the retelling of the sugar-cube story first related by Richard P. Feynman. The book also discusses the Carnot Cycle in an interesting way. The only problems I have with the book are that it is so short and that there aren't any problems to solve. However, the length is such that it is easy to leaf through and find a particular item, so I am rather torn on that. ( )
