Book Description

Energy is typically regarded as understandable, despite its multiple forms of storage and transfer. Entropy, however, is an enigma, in part because of the common view that it represents disorder. That view is flawed and hides entropy’s connection with energy. In fact, macroscopic matter stores internal energy, and that matter’s entropy is determined by how the energy is stored. Energy and entropy are intimately linked.

Energy and Entropy: A Dynamic Duo illuminates connections between energy and entropy for students, teachers, and researchers. Conceptual understanding is emphasised where possible through examples, analogies, figures, and key points.

Features:

  • Qualitative demonstration that entropy is linked to spatial and temporal energy spreading, with equilibrium corresponding to the most equitable distribution of energy, which corresponds to maximum entropy
  • Analysis of energy and entropy of matter and photons, with examples ranging from rubber bands, cryogenic cooling, and incandescent lamps to Hawking radiation of black holes
  • Unique coverage of numerical entropy, the 3rd law of thermodynamics, entropic force, dimensionless entropy, free energy, and fluctuations, from Maxwell's demon to Brownian ratchets, plus attempts to violate the second law of thermodynamics

Biography

Harvey S. Leff is Professor Emeritus of Physics at California State Polytechnic University in Pomona, California and Visiting Scholar at Reed College in Portland, Oregon. He has published widely in thermal physics, writing primarily for physics and chemistry teachers and students. With Andrew Rex, Leff co-edited Maxwell's Demon 2: Entropy, Classical and Quantum Information, Computing. He served as President of the American Association of Physics Teachers, and is a Fellow of the American Physical Society and the American Association of Physics Teachers, and a Consulting Editor for the American Journal of Physics. When not doing physics, Leff plays drums in two bands, The Leff Trio and Jazz Up, and he is the former drummer in The Out-Laws of Physics.

Reviews

"Not often does one have the chance to read a book that is the result of a lifetime of productive thought about an important subject, but such is the case with Harvey Leff’s Energy and Entropy.  One is astounded by the depth and breadth of this book.  And, what is more, Professor Leff has a deft way of appealing to various kinds of readers:  professionals who want to see the mathematics and those who desire a more conceptual understanding.  If you have room on your bookshelf for only one volume on thermodynamics, (and I don’t say this lightly) your choice should be Energy and Entropy."

— Don S. Lemons, Professor of Physic Emeritus, Bethel College, North Newton, Kansas

"Harvey Leff has used his lifelong interest and expertise in thermodynamics and statistical mechanics to write a delightful monograph on the relation between energy and entropy. The author explains the relation with thoughtful explanations including detailed examples, many of which are glossed over in most thermodynamics texts. Although most of the text is intended to expand on traditional material, more advanced topics such as the Jarznski equality are also discussed. The text should be of particular interest to students who are puzzled by the many subtleties of thermodynamics and by instructors who wish to offer a deeper understanding of the subject."

Harvey Goud, Clark University


"In this volume Harvey Leff has made a unique contribution by illustrating many connections between entropy and energy in a wide range of contexts, both theoretical and practical. The book begins with what is essentially a review of the laws of thermodynamics, with energy featured in connection with the first law and entropy in connection with the second. Although Leff includes the historical underpinnings of thermodynamics going back to the 19th century, he also addresses more contemporary topics such as black hole entropy, Landauer’s principle, the entropy of information and computation, and recent efforts to find violations of the second law. The book contains numerous simple but effective illustrations and graphs. A pedagogical feature that many readers will find effective is the use of “key points” that give a brief synopsis of the preceding section of text. I found that the key points often provide a bridge from one section to the next. This book is highly recommended as a learning tool for professionals and graduate students who seek a more comprehensive and wide-ranging treatment of entropy in its many forms and applications."
