"A monumental work on the flow of time, from the universe's creation to "Now," by the best-selling author of Physics for Future Presidents. "Now" is a simple concept--you're reading this sentence now. Yet a real definition of "now" has eluded even the great Einstein. We know that time stretches and is affected by gravity and velocity. Yet, as eminent physicist Richard A. Muller points out, it is only today that we have all the physics at hand--relativity, entropy, entanglement, antimatter, and the Big Bang--to explain the flow of time. With these building blocks in place, Muller reaches a startling conclusion: our expanding universe is continuously creating not only new space but also new time. The front edge of this new time is what we call "now," and this moment is truly unique--it is the only moment in which we can exercise our free will. Muller's thought-provoking vision is a powerful counter to established theories in science and philosophy, and his arguments will spark major debate about the most fundamental assumptions of our universe"-- Provided by publisher.

Another book written by a successful author about modern physics that contains a lot of rehashing of ideas, not explanatory in many areas, and some purely speculative and some non-scientific. If you are here to learn what “now” is, this book may leave you disappointed.
Examples: the author mentions absolute temperature, but does not define it as a negative 273 degrees below zero, centigrade, or why that scale is used, and its significance (molecular motion stops at zero absolute degrees). He mentions the mathematical function “cosine” (cos) but does not explain it. He states that he has a “soul,” a non-scientific idea by his own standards, which belongs in a book of religion, not science.
The science in the book jumps around in a jumbled way more suitable for a talk from an armchair than a book where the readers, presumably, want to learn about the ideas and hard facts that are known in an expository manner concerning the subject of time.
For “now,” as it were, skip this book and look elsewhere.

This is a thought-provoking and cognition-enervating book. Prof. Muller throws a lot of elegant stuff out there, sometimes I had to read a chapter over several times to glean his thoughts on the matter. If you have any interest in quantum physics (well explained) and the meaning of time, this is your book!
