Editorial Reviews Review

An Amazon Best Book of September 2016: Are you ready to have your mind blown? The topic of time and the theory of relativity sounds, well, merely theoretical until you realize upon reading Now that our GPS satellites have to compensate for time dilation constantly—otherwise they’d send us a location that’s inaccurate by almost a mile and a half. Muller’s enthusiasm for physics propels the reader through complex ideas such as space-time, entropy, the flexibility of space, lightspeed loopholes, and his dislike of string theory. Calvin and Hobbes cartoons and Terminator references sit side by side with equations such as Entropy = k log W—but don’t let that alarm you. The best nonfiction books expand your knowledge, and Now takes that effort one step further by expanding how you actually think about so-called reality. Muller’s love of physics will charm even those who want nothing to do with the subject, and even more engaging is his humility about the extent of our current understanding of how the universe works: “I think we can take joy in the speculation that we are not running out of important things to discover.” With Now, readers will find plenty that will expand their brains and prepare them for that next amazing discovery. --Adrian Liang, The Amazon Book Review --This text refers to the hardcover edition.


“Mind-blowing ideas demand to be shared.…[Muller] posits a theory that seems at once plausible and―surprisingly, for a book with equations―one worth not spoiling.”
- Time

“Richard Muller is a leading physicist, but he’s also intellectually restless. That’s a potent combination, with the power to generate transformative ideas about ourselves and our relationship to the universe. In Now: The Physics of Time, Muller hypothesizes how time itself might be created or destroyed. Maybe it’s right. Maybe it’s wrong. But along the way he’s given you a master class in what time is and how and why we perceive it the way we do.”
- Neil deGrasse Tyson, astrophysicist and host of Cosmos: A Spacetime Odyssey

“Muller has taken a remarkably fresh and exciting approach to the analysis of time. With his usual clarity and wit, he proceeds from solidly established principles―each a fascinating story in its own right―but when he gets to the meaning of the flow of time and now, he forges a new path. I expect controversy!”
- Saul Perlmutter, winner of the Nobel Prize in Physics

“Can science shed light on time’s dark mysteries? Richard Muller thinks it can, making his case in this clear, evocative, and wide-reaching investigation of how nature may generate the flow of time. Must-reading for all concerned with the why behind when.”
- Timothy Ferris, author of Coming of Age in the Milky Way

“A provocative, strongly argued book on the fundamental nature of time. As an experimental cosmologist who has initiated some of the most important experiments of our time, Muller knows well where the limits of science are, and he keeps us interested by his ability to work close to that edge.”
- Lee Smolin, author of Time Reborn

“The strength of this book lies in Muller’s experience as a lecturer and teacher, which has enabled him to describe and explain difficult concepts with simplicity.… [Now] provides a concise master class in understanding the essentials of physics.”
- Science

“Time spent with Muller will transform readers' understanding of time itself.…A mind-expanding venture to the frontiers of science―and beyond!”
- Booklist (starred review)

“The kind of mind-expanding read that will give you something to think about late at night. Muller's passion for his topic shines through on every page.”
- The Independent --This text refers to the hardcover edition.
