A philosophical perspective to statistical mechanics for graduate students and researchers in the foundations and philosophy of physics.

"Time asymmetric phenomena are successfully predicted by statistical mechanics. Yet the foundations of this theory are surprisingly shaky. Its explanation for the ease of mixing milk with coffee is incomplete, and even implies that un-mixing them should be just as easy. In this book the authors develop a new conceptual foundation for statistical mechanics that addresses this difficulty. Explaining the notions of macrostates, probability, measurement, memory, and the arrow of time in statistical mechanics, they reach the startling conclusion that Maxwell's Demon, the famous perpetuum mobile, is consistent with the fundamental physical laws. Mathematical treatments are avoided where possible, and instead the authors use novel diagrams to illustrate the text. This is a fascinating book for graduate students and researchers interested in the foundations and philosophy of physics."--

About 120 years ago, James Clerk Maxwell introduced his now legendary hypothetical "demon" as a challenge to the integrity of the second law of thermodynamics. Fascination with the demon persisted throughout the development of statistical and quantum physics, information theory, and computer science--and linkages have been established between Maxwell's demon and each of these disciplines. The demon's seductive quality makes it appealing to physical scientists, engineers, computer scientists, biologists, psychologists, and historians and philosophers of science. Until now its important source material has been scattered throughout diverse journals. This book brings under one cover twenty-five reprints, including seminal works by Maxwell and William Thomson; historical reviews by Martin Klein, Edward Daub, and Peter Heimann; information theoretic contributions by Leo Szilard, Leon Brillouin, Dennis Gabor, and Jerome Rothstein; and innovations by Rolf Landauer and Charles Bennett illustrating linkages with the limits of computation. An introductory chapter summarizes the demon's life, from Maxwell's illustration of the second law's statistical nature to the most recent "exorcism" of the demon based on a need periodically to erase its memory. An annotated chronological bibliography is included. Originally published in 1990. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

You arrive at your office and unpack your breakfast from the local deli. The piping-hot coffee and chilly orange juice you purchased just minutes ago are now both disappointingly lukewarm. Why can't the coffee "steal" heat from the juice to stay hot? Why does even the most state-of-the-art car operate at a mere 30 percent efficiency--and why can't Detroit ever better the odds, no matter what space age materials we invent? Why can't some genius make a perpetual motion machine? The answers lie in the field of thermodynamics, the study of heat, which turns out to be the key to an astonishing number of scientific puzzles. If you want to know what's happening in the physical world, you've got to follow the heat. In Maxwell's Demon: Why Warmth Disperses and Time Passes, physics professor Hans Christian von Baeyer tells the story of heat through the lives of the scientists who discovered it, most notably James Clerk Maxwell, whose demonic invention has bedeviled generations of physics students with its light-fingered attempts to flout the laws of thermodynamics. An intelligent, submicroscopic gremlin who could sort atoms as they flew at him, Maxwell's Demon would effectively make an impossible task--forcing heat to flow backward--possible. Explaining why the Demon can't have his day has been an intellectual gauntlet taken up by a century and a half of the world's most brilliant scientists, whose discoveries Professor von Baeyer vividly etches. The centuries-old discipline of thermodynamics informs today's most cutting-edge research in chaos, complexity, and the grand unified theory of everything--physics' Holy Grail. Even more amazing, the study of heat turns out to explainsomething seemingly unrelated--time, and why it can run in only one direction. With his trademark elegant prose, eye for lively detail, and gift for lucid explanation, Professor von Baeyer turns the contemplation of a cooling teacup into a beguiling portrait of the birth of a science with relevance to almost every aspect of our lives. Readers will find themselves rooting for Maxwell's ever-mischievous Demon even as they come to appreciate that he is doomed to failure.

This autumn, life is catching up with Thomas Quinn. Five years ago, his sometime friend Andrew Black wrote a mystery novel that sold a million copies and then disappeared. Now could it be that Quinn is being stalked by the hero of Black’s book? His wife, Imogen, usually has the answers, but she’s working on the other side of the world and talking to her on webcam just isn’t the same. Quinn finds himself in a world that might well be coming apart at the seams. If he can find Black, he might start finding answers. Maxwell’s Demon forges an entirely new blend of mystery—somewhere between detective fiction, ghost story and philosophical quest. Providing the same white-knuckle thrills as Hall’s first novel, The Raw Shark Texts, this new book is also a freewheeling investigation into the magic power locked inside the alphabet, love through the looking glass, the bond between parents and children and, at its heart, the quest for meaning in a world that, with each passing season, seems to become more chaotic and untidy.

In this collection of short stories, Ken Kesey challenges public and private demons with a wrestler's brave and deceptive embrace, making it clear that the energy of madness must live on.

How scientists through the ages have conducted thought experiments using imaginary entities—demons—to test the laws of nature and push the frontiers of what is possible Science may be known for banishing the demons of superstition from the modern world. Yet just as the demon-haunted world was being exorcized by the enlightening power of reason, a new kind of demon mischievously materialized in the scientific imagination itself. Scientists began to employ hypothetical beings to perform certain roles in thought experiments—experiments that can only be done in the imagination—and these impish assistants helped scientists achieve major breakthroughs that pushed forward the frontiers of science and technology. Spanning four centuries of discovery—from René Descartes, whose demon could hijack sensorial reality, to James Clerk Maxwell, whose molecular-sized demon deftly broke the second law of thermodynamics, to Darwin, Einstein, Feynman, and beyond—Jimena Canales tells a shadow history of science and the demons that bedevil it. She reveals how the greatest scientific thinkers used demons to explore problems, test the limits of what is possible, and better understand nature. Their imaginary familiars helped unlock the secrets of entropy, heredity, relativity, quantum mechanics, and other scientific wonders—and continue to inspire breakthroughs in the realms of computer science, artificial intelligence, and economics today. The world may no longer be haunted as it once was, but the demons of the scientific imagination are alive and well, continuing to play a vital role in scientists' efforts to explore the unknown and make the impossible real.

What is the role and meaning of probability in physical theory, in particular in two of the most successful theories of our age, quantum physics and statistical mechanics? Laws once conceived as universal and deterministic, such as Newton‘s laws of motion, or the second law of thermodynamics, are replaced in these theories by inherently probabilistic laws. This collection of essays by some of the world‘s foremost experts presents an in-depth analysis of the meaning of probability in contemporary physics. Among the questions addressed are: How are probabilities defined? Are they objective or subjective? What is their explanatory value? What are the differences between quantum and classical probabilities? The result is an informative and thought-provoking book for the scientifically inquisitive.

Mixing myth, entropy, and Angry Birds, Randall Schweller brings a novel perspective to international studies. Just what exactly will follow the American century? This is the question Randall L. Schweller explores in his provocative assessment of international politics in the twenty-first century. Schweller considers the future of world politics, correlating our reliance on technology and our multitasking, distracted, disorganized lives with a fragmenting world order. He combines the Greek myth of the Golden Apple of Discord, which explains the start of the Trojan War, with a look at the second law of thermodynamics, or entropy. "In the coming age,” Schweller writes, “disorder will reign supreme as the world succumbs to . . . entropy, an irreversible process of disorganization that governs the direction of all physical changes taking place in the universe.” Interweaving his theory of global disorder with issues on the world stage—coupled with a disquisition on board games and the cell phone app "Angry Birds"—Schweller’s thesis yields astonishing insights. Maxwell’s Demon and the Golden Apple will appeal to leaders of multinational corporations and government programs as well as instructors of undergraduate courses in international relations.

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
