About this listen

“Now” is a simple yet elusive concept. You are reading the word now right now. But what does that mean? What makes the ephemeral moment "now" so special? Its enigmatic character has bedeviled philosophers, priests, and modern-day physicists from Augustine to Einstein and beyond. Einstein showed that the flow of time is affected by both velocity and gravity, yet he despaired at his failure to explain the meaning of now. Equally puzzling: Why does time flow? Some physicists have given up trying to understand and call the flow of time an illusion, but the eminent experimentalist physicist Richard A. Muller protests. He says physics should explain reality, not deny it.

In Now, Muller does more than poke holes in past ideas; he crafts his own revolutionary theory, one that makes testable predictions. He begins by laying out - with the refreshing clarity that made Physics for Future Presidents so successful - a firm and remarkably clear explanation of the physics building blocks of his theory: relativity, entropy, entanglement, antimatter, and the big bang. With the stage then set, he reveals a startling way forward.

Muller points out that the standard big bang theory explains the ongoing expansion of the universe as the continuous creation of new space. He argues that time is also expanding and that the leading edge of the new time is what we experience as now. This thought-provoking vision has remarkable implications for some of our biggest questions, not only in physics but also in philosophy, including the ongoing debate about the reality of free will. Moreover, his theory is testable. Muller's monumental work will spark major debate about the most fundamental assumptions of our universe and may crack one of physics' longest-standing enigmas.

Critic reviews

"Mind-blowing…[Muller] posits a theory that seems at once plausible and - surprisingly, for a book with equations - one worth not spoiling." (Time)

"[A] concise master class in understanding the essentials of physics." (Lisa Jardine-Wright, Science)

"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)

I'm an artist and writer, very right-brained, sadly inept in mathematics and the sciences. Yet I have always been fascinated by Physics. Physics has remained a bewildering foreign language to me. Over the years, I thought if I listened to enough words spoken in the language Physics, I would suddenly understand it. Until this book, my hope has been unfulfilled. However, about half way through this book, my brain experienced an awakening to the notion of symmetry. I can't explain it, but from that moment forward, I understood, haltingly it is true, how and why Physics reveals and predicts the universe and life. I am going to listen to this book from the beginning again and again.

Bewildering, mind blowing, ultimately enlightening

I like Richard Muller and love Physics for Future Presidents. He jumps out on a limb in the book but unfortunately fails to make his case.

The best I can say is that he is clever to a point with semantics but really doesn't open the doors to a great, or as he would say, a more correct interpretation of time. Because entropy is a fluid process that cannot define 'now' is no reason to toss entropy as a means of defining time as best we are able. Really, time is fluid and there is no now. Before you can say now, the time has past. There is not frozen moment of time.

The book is interesting but I would not say it's ground breaking.

No. Sorry, Just No

I now understand why we can't travel to the future and why the past cannot be changed. The author assumes that no one would want to travel to an immutable past but just to see it and be there would be better than anything - yes, even set. The person reading did an amazing job - he read with an understanding of the material that could only be exceeded by the author. Great book!

Extremely informative....

This audible is definitely worth a listen if you want to gain further insights into fundamental physics. The author, who is a highly-cited physicist in his practice, doesn't go super deep into any one topic, and not all critical topics of relevance are covered; but he does give what I consider to be really good, extensive explanations regarding entropy, quantum particles/fields, quantum gravity, etc.

It might fizzle out somewhat in the end; but it's not because of topics irrelevant to physics. He ends up digging further into borderline-metaphysics than most of his intended audience might appreciate, assuming that audience to be science-minded people who only respect falsifiable hypotheses. But eventually physicists will have to explain the borderline physics that he mentions. Besides, he never suggests pursuing any studies that can't be tested and falsified, so it's not "spiritual clap-trap".

Great insights in real physics; some "metaphysics"

One of the better popular audience books written by active researchers: Muller includes a lot of relevant detail while keeping the narrative accessible and enjoyable. I enjoyed the historical perspective and liberal use of personal anecdotes. The philosophical sections can drag a bit, but cover important epistemological topics that modern scientists often paper over. Overall, an excellent synthesis with broad scope.

Excellent and accessible review of modern physics

This book goes through a number of scientific areas which are interesting but ends up not delivering the answer to the question of now.

Besides describing time expansion being similar to space expansion, it seemed to me that now is a topic for further study, waiting for someone to come along and figure it out.

What did you love best about Now?

A great summary of the history as well as the latest thinking about time and physics. Great

BEST PHYSICS BOOK I HAVE READ

Written for someone with a strong grasp on physics and physical concepts. Requires higher than average working knowledge of theoretical physics and mathematics.

Overly technical

.. and a lot of room for more lucidity.

Unsurprisingly the overarching question of the time remained deprived of a compelling answer, and the proposed theory of its direction lacked some essential details, and neglected to fill in some fundamental gaps, e.g. if the creation of new spacetime puts a mandatory direction on time, then why does it not put a similar direction on space? If newly created space doesn't stop us from moving to and fro in each of its 3 dimension then why the newly created time doesn't allow that? The whole basic question of the direction of time remained unsatisfied IMO.

Some good science - some bad philosophy - ...

Really need to see the equations and figures. The reader tried, but it doesn't work

Great book, but does not work well as an audio
