The book presents the three laws of thermodynamics: the first law (conservation of energy)in chapters 1-4, the second law (dispersal of energy) in chapters 5-9, and the third law (low temperature behavior) in chapter 14. Other chapters apply thermodynamics to light, chemistry, biology, geology, and cosmology. The authors present thermodynamics using both classical and statistical mechanical arguments. References are listed for further study of topics.Although the book is intended for a general audience, the book will be interesting even to a reader who already has some familiarity with thermodynamics because the book probably treats at least a few applications with which he is unfamiliar. The book also makes a number of refreshing admissions about the limits of thermodynamics; for example, thermodynamics can't be strictly applied to living organisms (p. 297), and in general relativity, energy need not be conserved (p. 370).The book requires a knowledge of simple algebra and logarithms; however, a tutorial on these subjects is presented in an appendix.
