Cumberbatch possesses a deep and rich voice and reads the text in a precise but unhurried manner, with the result that we feel as if we are getting an exposition by an erudite but gentle teacher…Chapter by chapter, Rovelli shows how modern physics has annihilated common understandings of time. And both the writing and vocal delivery are beautiful…Some elements of Rovelli's narrative, like the material on light cones and loop quantum gravity and spin networks, many readers will find incomprehensible. But the many other excellent explanations of science, the heart and humanity of the book, its poetry and its gentle tone raise it to the level and style of such great scientist-writers as Lewis Thomas and Rachel Carson. Listening to Rovelli's book, as read by Cumberbatch, we hear the warm voice of a modest man searching to understand not only the physical world but also how he, and we, perceive it.

In this far-reaching text rife with references to poets, artists, and philosophers, as well as scientists, theoretical physicist Rovelli (Seven Brief Lessons on Physics) takes readers through the current scientific understanding of time, stating that “we inhabit time as fish live in water.” Rovelli begins with a look at why time, Rainer Maria Rilke’s “eternal current,” only flows forward. Humans can see the past but not the future, he writes, because of how heat flows, from hot to cold. He states that “only where there is heat is there a distinction between past and future,” using as an example a film of a rolling ball gradually slowing, due to heat-producing friction; if run backwards, the film becomes absurd. Entropy, “the quantity that measures this irreversible progress of heat in only one direction,” provides the direction of “time’s arrow.” Meanwhile, the human perception of simultaneity, the idea of “now” in two different locations, is an illusion, an insight that Rovelli calls “perhaps the greatest and strangest of Einstein’s discoveries.” In considering time, Rovelli also explores quantum time, loop theory, and the nature of memory. As much philosophy as physics, this accessible study introduces the complex questions behind the perception and study of time. (May)

Highly original. . . . Chapter by chapter, Rovelli shows how modern physics has annihilated common understandings of time. . . . the many other excellent explanations of science, the heart and humanity of the book, its poetry and its gentle tone raise it to the level and style of such great scientist-writers as Lewis Thomas and Rachel Carson.” —Alan Lightman, New York Times Book Review

“ An elegant grapple with one of physics’ deepest mysteries. . . .A masterly writer. . . . In this little gem of a book, Mr. Rovelli first demolishes our common-sense notion of time. . . .an ambitious book that illuminates a thorny question, that succeeds in being a pleasurable read.” —Wall Street Journal

“No one writes about the cosmos like theoretical physicist Carlo Rovelli. . . Rovelli’s new story of time is elegant and lucidly told, whether he is revealing facts or indulging in romantic-philosophic speculation about the nature of time.” —The Washington Post

“An incredible book. . . [Rovelli] manages to communicate some of the most complex and inspiring ideas we have about time with a poetry, charm and wit that is infectious.” —Benedict Cumberbatch

“Rovelli has crafted an accessible, mind-­expanding read that challenges our perceptions of time, space and reality.” —TIME

“A deep—and remarkably readable—dive into the fundamental nature of time. . . written with enough charm and poetry to engage the imagination of anyone who reads it.” —Financial Times 

“The Order of Time, by Carlo Rovelli, hardly seems like pool-side reading, but anyone with the least interest in the science of the physical world will be by turns astonished, baffled and thrilled by what Rovelli has to say about the true nature of time, which has little in common with our everyday conception of it. Rovelli is the poet of quantum physics.” —John Banville

“We live in an age of wonderful science writing, and Carlo Rovelli’s new book, The Order of Time, is an example of the very best. Time is something we think we know about instinctively; here he shows how profoundly strange it really is.” —Philip Pullman 

“Mind-bending.” —Michael Pollan

“Rovelli is a wonderful writer, and so even when you (or perhaps I should just stick to the first-person singular) don’t know what’s going on, he comes up with enjoyable, occasionally beautiful metaphors to help you (me). . .  The ideas in The Order of Time are extraordinary, and I rather fear you should read it” —Nick Hornby, The Believer

“The Order of Time is a little wonder of a book. It provides surprising insights into an increasingly mysterious world, offers warmly humane reflections on our existential condition, and sustains a virtual conversation that will continue long after the reading has ceased.” —PopMatters

“A dizzying, poetic work” —The Guardian

“A compact and elegant book” —Nature

“Rovelli, a physicist and one of the founders of loop quantum gravity theory, uses literary, poetical and historical devices to unravel the properties of time, what it means to exist without time and, at the end, how time began.” —Scientific American

“Physics' literary superstar makes us rethink time . . . The Order of Time will surely establish Rovelli among the pantheon of great scientist-communicators . . . More of this please” —New Scientist

“Where other writers struggle to get their complex ideas across, Rovelli introduces profound notions with ease, using simple but evocative language . . . He also has a knack for mixing his serious enterprise with a sense of humor.” —Science Magazine

“In this fascinating new book, Carlo Rovelli weaves together physics, philosophy, and art to explore the enduring mystery of time itself.” —Bustle

“An elegantly concise primer makes theoretical physics intelligible . . . it would be to do a disservice to Rovelli and this stunningly written book, to say that brevity is its main virtue.” —The Times (UK)  

Keep your finger near the rewind buttons as you listen to this stunning exploration of the physics and philosophies of time. Rovelli is a patient teacher, but the subject matter is very difficult to grasp. Fortunately, we have narrator Benedict Cumberbatch’s talents to carry us along. His velvety bass voice is a delight to listen to—comforting and companionable, with perfect cadences to signal when the difficult concepts he’s speaking about need extra attention (or a 30-second skip-back to hear again). The result is a performance that feels like a conversation with Professor Rovelli himself steadily guiding you as he dismantles all notions of time and helps you rebuild your understanding of it.

Undeterred by a subject difficult to pin down, Italian theoretical physicist Rovelli (Reality Is Not What It Seems: The Journey to Quantum Gravity, 2017, etc.) explains his thoughts on time.Other scientists have written primers on the concept of time for a general audience, but Rovelli, who also wrote the bestseller Seven Brief Lessons on Physics, adds his personal musings, which are astute and rewarding but do not make for an easy read. "We conventionally think of time," he writes, "as something simple and fundamental that flows uniformly, independently from everything else, uniformly from the past to the future, measured by clocks and watches. In the course of time, the events of the universe succeed each other in an orderly way: pasts, presents, futures. The past is fixed, the future open….And yet all of this has turned out to be false." Rovelli returns again and again to the ideas of three legendary men. Aristotle wrote that things change continually. What we call "time" is the measurement of that change. If nothing changed, time would not exist. Newton disagreed. While admitting the existence of a time that measures events, he insisted that there is an absolute "true time" that passes relentlessly. If the universe froze, time would roll on. To laymen, this may seem like common sense, but most philosophers are not convinced. Einstein asserted that both are right. Aristotle correctly explained that time flows in relation to something else. Educated laymen know that clocks register different times when they move or experience gravity. Newton's absolute exists, but as a special case in Einstein's curved space-time. According to Rovelli, our notion of time dissolves as our knowledge grows; complex features swell and then retreat and perhaps vanish entirely. Furthermore, equations describing many fundamental physical phenomena don't require time.As much a work of philosophy as of physics and full of insights for readers willing to work hard.
