"Physics leaves big questions unanswered. For example, why does time seem to move only from the past toward the future? In fact, there is no good definition of past, present, and future. Experiments show there is no universal "flowing river of time." Is time "the fourth dimension?" Is there a "place" we can visit called "the past?" Is there no unifying theory to join the theories of quantum mechanics and relativity? The nature of time is critical in answering these questions. Physics is not wrong - simply incomplete. More facts have been learned about our universe in the last thirty years than have been learned in all of previous history. Mostly what has been learned is how little we actually know. The nature of time is a good example. This book describes experiments that have proved that gravity, velocity, and acceleration slow time. Analysis shows that (1) perception of distance and time depends on relative velocity, (2) time can slow and stop, (3) time gets really strange near black holes, (4) photons traveling toward each other at the speed of light see the other moving only at the speed of light, due to time effects; and there are other strange effects. The truth is that most time experiment results have no real explanation. In physics there is no good definition for time and no logic foundation for a definition of time - until this book. Enter the new science and technology of time. Here the relatively new sciences of computer technology and communication theory have an important contribution to make. At the heart of the science we find the computer logic of state machines and the physical structure of information as a physical entity. In this world, "state change" is the pivot around which the world turns. We learn that logic is essential for understanding how time works. We discover how state change is essential for the very existence of time! Logic symbols provide a framework for thought about time. We even find a basis for some of the definitions physics has been searching for. We find an information-based state- transition-based definition of time. There is a way to define past, present, and future. In this book we find very compelling motivation for some interesting conclusions. For example, time is essentially the result of state transitions. If nothing happens, there is no evidence of time passing. We find that energy exchange motivates time. There is no experience of time without sequence of events. Could the new science and technology of time be the next leap forward in physics? Many current science writers seem to think so"--

We say that the processes going on in the world about us are asymmetric in time or display an arrow of time. Yet this manifest fact of our experience is particularly difficult to explain in terms of the fundamental laws of physics. This volume reconciles these profoundly conflicting facts.

A series of classic lectures, delivered in 1960 and recorded for the BBC. This is Feynman's unique take on the problems and puzzles that lie at the heart of physical theory - with Newton's Law of Gravitation; on whether time can ever go backwards; on maths as the supreme language of nature. Demonstrates Feynman's knack of finding the right everyday illustration to bring out the essence of a complicated principle - eg brilliant analogy between the law of conservation energy and the problem of drying yourself with wet towels. 'Feynman's style inspired a generation of scientists. This volume remains the best record I know of his exhilarating vision' - Paul Davies

Advances made by physicists in understanding matter, space, and time and by astronomers in understanding the universe as a whole have closely intertwined the question being asked about the universe at its two extremesâ€"the very large and the very small. This report identifies 11 key questions that have a good chance to be answered in the next decade. It urges that a new research strategy be created that brings to bear the techniques of both astronomy and sub-atomic physics in a cross-disciplinary way to address these questions. The report presents seven recommendations to facilitate the necessary research and development coordination. These recommendations identify key priorities for future scientific projects critical for realizing these scientific opportunities.

One of TIME’s Ten Best Nonfiction Books of the Decade "Meet the new Stephen Hawking . . . The Order of Time is a dazzling book." --The Sunday Times From the bestselling author of Seven Brief Lessons on Physics, Reality Is Not What It Seems, Helgoland, and Anaximander comes a concise, elegant exploration of time. Why do we remember the past and not the future? What does it mean for time to "flow"? Do we exist in time or does time exist in us? In lyric, accessible prose, Carlo Rovelli invites us to consider questions about the nature of time that continue to puzzle physicists and philosophers alike. For most readers this is unfamiliar terrain. We all experience time, but the more scientists learn about it, the more mysterious it remains. We think of it as uniform and universal, moving steadily from past to future, measured by clocks. Rovelli tears down these assumptions one by one, revealing a strange universe where at the most fundamental level time disappears. He explains how the theory of quantum gravity attempts to understand and give meaning to the resulting extreme landscape of this timeless world. Weaving together ideas from philosophy, science and literature, he suggests that our perception of the flow of time depends on our perspective, better understood starting from the structure of our brain and emotions than from the physical universe. Already a bestseller in Italy, and written with the poetic vitality that made Seven Brief Lessons on Physics so appealing, The Order of Time offers a profoundly intelligent, culturally rich, novel appreciation of the mysteries of time.

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. In particular, the book offers an analysis of the physical concept of time.

This book on the structure and role of time in physical theories addresses itself to scientists and philosophers intereste:'i in the 'no man's lard' between science and philosophy, in particular between physics and philoso phy. The p:lint of departure is physical time, Le. time as usErl 1: physicists in their theories; but the analysis is not oonfined to a purely physical level but caries the problem into the domain of philosophical in quiry. Altoough the book presupp:lses some knowledge of physics, I have avoided, wherever p:lssible, the use of advanced mathematics and technical details. Of all the people woo have been of help in writing this book, I would first of all like to mention Paul Scheurer and Guy Debrock who were my primary mentors in science and philosophy. This sttrly is a revision of my dissertation [Kroes 1982a] which I wrote under the stimulating guidance of Scheurer; many of the ideas ex posed here have their origin in his work and were developErl in frequent discussions with him. Guy Debrock not only stimulated my interest in philosophy but also made valuable suggestions. Witoout any overstatement, I dare say that without their assistence, this book would never have been written. Furthernore, I would like to thank D. Dieks, J.J.C.
