"The physical asymmetry of nature under time reversal is analysed in this essay. The author investigates the most important classes of phenomena that characterize a direction of time: radiation, thermodynamics, quantum phenomena, and the structure of spacetime. Their relations and the search for a cosmological common root of these "arrows of time" and of the traditional concept of causality are discussed. Particular emphasis is placed on quantum indeterminism. It is argued that a common root may be found in the properties of the time-independent wave function of the universe that arises from the quantization of general relativity. This requires that the physical concept of time is reduced to a correlation between physical states, including those characterizing clocks and observers. The description of irreversible phenomena is shown to be fundamentally "observer-related" in a way that can be formalized following Zwanzig. The book is aimed mainly at the student or scientist seeking an overview of the whole issue. Compared to the German version the book has been widely revised and extended."
"For this third edition H.D. Zeh has thoroughly revised his book to include important new results. At the same time it retains the features that make it a classic text on irreversibility, and one which clearly distinguishes the latter from time asymmetry. New findings are presented particularly in the chapters on the arrow of time in quantum mechanics and quantum cosmology. Concepts such as decoherence and timelessness are discussed. The book has gained a reputation for its thorough survey of what is known about irreversibility in physics. It investigates physical phenomena in classical, quantum and cosmological settings. Both physicists and philosophers of science who reviewed earlier editions considered this book a magnificent survey, a concise, technically sophisticated, up-to-date discussion of the subject, showing fine sensitivity to crucial conceptual subtleties."@en
"This book has been thoroughly revised to include important new results. At the same time it retains the features that make it a classic text on irreversibility, and one which clearly distinguishes the latter from those time asymmetries which may be compensated for by other asymmetries. The book investigates irreversible phenomena in classical, quantum and cosmological settings. In particular, this fourth edition contains a revised treatment of radiation damping as well as extended sections on dynamical maps, quantum entanglement and decoherence, arrows of time hidden in various interpretations of quantum theory, and the emergence of time in quantum gravity. Both physicists and philosophers of science who reviewed earlier editions considered this book a magnificent survey, a concise, technically sophisticated, up-to-date discussion of the subject, showing showing fine sensitivity to crucial conceptual subtleties."
"This thoroughly revised 5th edition of Zeh's classic text investigates irreversible phenomena and their foundation in classical, quantum and cosmological settings. It includes new sections on the meaning of probabilities in a cosmological context, irreversible aspects of quantum computers, and various consequences of the expansion of the Universe. Many other sections have been rewritten. In particular, the book contains an analysis of the physical concept of time, a detailed treatment of radiation damping as well as extended sections on quantum entanglement and decoherence, arrows of time hidden in various interpretations of quantum theory, and the emergence of time in quantum gravity. Both physicists and philosophers of science will find in this book a magnificent survey and a concise, technically sophisticated, up-to-date discussion which shows fine sensitivity to crucial conceptual subtleties. "The discussion is lucid and intuitive without glossing over the important details." Max Tegmark, MIT."@en
"This book arose from a series of lectures which I gave at the University of Heidelberg during the summer terms of 1979,1982 and 1986. They led in 1984 the publication in German of Die Physik der Zeitrichtung, which appeared to as Vol. 200 of the Springer Lecture Notes in Physics. The present English version is not merely a translation of these notes, but has been widely revised and extended. The number of changes and additions roughly increases with chapter number. Chaps. 5 and 6 have been completely rewritten (except for Sect. 5. 1, which is a revised version of the former {sect} 5. 2). The new title is intended to express the somewhat more ambitious program of this book as compared to its German predecessor. My interest in this subject stemmed originally from an attempt to place the quantum mechanical measurement process in its proper relation to other irreversible phenomena. It soon became evident that statistical thermody namics is too limited for the search for the common roots of the obviously related arrows of time. It is precisely the interconnectedness of many areas of physics, and not least their relation to some fundamental concepts (or per haps prejudices) of epistemology, which sustained my fascination with the subject of this book over many years. Thus it was not my intention to de scribe technicalities or mathematical problems, but to point out the essential physical ideas (which are often overlooked)."@en
"The asymmetry of natural phenomena under time reversal is striking. Here Zehinvestigates the most important classes of physical phenomena that characterize the arrow of time, discussing their interrelations as well as striving to uncover a cosmological common root of the phenomena, such as the time-independent wave function of the universe. The description of irreversible phenomena is shown to be fundamentally "observer-related". Both physicists and philosophers of science who reviewed the first edition considered this book a magnificent survey, a concise, technically sophisticated, up-to-date discussion of the subject, showing fine sensivity to some of the crucial philosophicalsubtleties. This new and expanded edition will be welcomed by both students and specialists."
