The Order of Time

The Order of Time PDF Author: Carlo Rovelli
Publisher: Penguin
ISBN: 073521610X
Category : Science
Languages : en
Pages : 258

Book Description
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.

The Physical Basis of The Direction of Time PDF Author: H. Dieter Zeh
Publisher: Springer Science & Business Media
ISBN: 3662027593
Category : Science
Languages : en
Pages : 194

Book Description
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.

Time's Arrows Today

Time's Arrows Today PDF Author: Steven F. Savitt
Publisher: Cambridge University Press
ISBN: 9780521599450
Category : Science
Languages : en
Pages : 348

Book Description
While experience tells us that time flows from the past to the present and into the future, a number of philosophical and physical objections exist to this commonsense view of dynamic time. In an attempt to make sense of this conundrum, philosophers and physicists are forced to confront fascinating questions, such as: Can effects precede causes? Can one travel in time? Can the expansion of the Universe or the process of measurement in quantum mechanics define a direction in time? In this book, researchers from both physics and philosophy attempt to answer these issues in an interesting, yet rigorous way. This fascinating book will be of interest to physicists and philosophers of science and educated general readers interested in the direction of time.

Time and Chance

Time and Chance PDF Author: David Z Albert
Publisher: Harvard University Press
ISBN: 0674020138
Category : Science
Languages : en
Pages : 188

Book Description
This book is an attempt to get to the bottom of an acute and perennial tension between our best scientific pictures of the fundamental physical structure of the world and our everyday empirical experience of it. The trouble is about the direction of time. The situation (very briefly) is that it is a consequence of almost every one of those fundamental scientific pictures--and that it is at the same time radically at odds with our common sense--that whatever can happen can just as naturally happen backwards. Albert provides an unprecedentedly clear, lively, and systematic new account--in the context of a Newtonian-Mechanical picture of the world--of the ultimate origins of the statistical regularities we see around us, of the temporal irreversibility of the Second Law of Thermodynamics, of the asymmetries in our epistemic access to the past and the future, and of our conviction that by acting now we can affect the future but not the past. Then, in the final section of the book, he generalizes the Newtonian picture to the quantum-mechanical case and (most interestingly) suggests a very deep potential connection between the problem of the direction of time and the quantum-mechanical measurement problem. The book aims to be both an original contribution to the present scientific and philosophical understanding of these matters at the most advanced level, and something in the nature of an elementary textbook on the subject accessible to interested high-school students.

A Sense of Direction

A Sense of Direction PDF Author: Gideon Lewis-Kraus
Publisher: Penguin
ISBN: 1594631492
Category : Biography & Autobiography
Languages : en
Pages : 386

Book Description
In medieval times, a pilgrimage gave the average Joe his only break from the daily grind. For Gideon Lewis-Kraus, it promises a different kind of escape. Determined to avoid the fear and self-sacrifice that kept his father, a gay rabbi, closeted until midlife, he has moved to anything-goes Berlin. But the surfeit of freedom there has begun to paralyze him, and when a friend extends a drunken invitation to join him on an ancient pilgrimage route across Spain, Lewis-Kraus packs his bag, grateful for the chance to wake each morning with a sense of direction. Irreverent, moving, hilarious, and thought-provoking, A Sense of Direction is Lewis-Kraus’s dazzling riff on the perpetual war between discipline and desire, and its attendant casualties. Across three pilgrimages and many hundreds of miles, he completes an idiosyncratic odyssey to the heart of a family mystery and a human dilemma: How do we come to terms with what has been and what is—and find a way forward, with purpose?

From Eternity to Here

From Eternity to Here PDF Author: Sean Carroll
Publisher: Penguin
ISBN: 0452296544
Category : Science
Languages : en
Pages : 466

Book Description
"An accessible and engaging exploration of the mysteries of time." -Brian Greene, author of The Elegant Universe Twenty years ago, Stephen Hawking tried to explain time by understanding the Big Bang. Now, Sean Carroll says we need to be more ambitious. One of the leading theoretical physicists of his generation, Carroll delivers a dazzling and paradigm-shifting theory of time's arrow that embraces subjects from entropy to quantum mechanics to time travel to information theory and the meaning of life. From Eternity to Here is no less than the next step toward understanding how we came to exist, and a fantastically approachable read that will appeal to a broad audience of armchair physicists, and anyone who ponders the nature of our world.

What Makes Time Special?

What Makes Time Special? PDF Author: Craig Callender
Publisher: Oxford University Press
ISBN: 0192517856
Category : Science
Languages : en
Pages : 336

Book Description
As we navigate through life we instinctively model time as having a flowing present that divides a fixed past from open future. This model develops in childhood and is deeply saturated within our language, thought and behavior, affecting our conceptions of the universe, freedom and the self. Yet as central as it is to our lives, physics seems to have no room for this flowing present. What Makes Time Special? demonstrates this claim in detail and then turns to two novel positive tasks. First, by looking at the world "sideways" - in the spatial directions — it shows that physics is not "spatializing time" as is commonly alleged. Even relativity theory makes significant distinctions between the spacelike and timelike directions, often with surprising consequences. Second, if the flowing present is an illusion, it is a deep one worthy of explanation. The author develops a picture whereby the temporal flow arises as an interaction effect between an observer and the physics of the world. Using insights from philosophy, cognitive science, biology, psychology and physics, the theory claims that the flowing present model of time is the natural reaction to the perceptual and evolutionary challenges thrown at us. Modeling time as flowing makes sense even if it misrepresents it.
