IRB Media Summary of Richard A. Muller's Now

Annotation

Please note: This is a companion version & not the original book. Book Preview: #1 The meaning of now is one of the many mysteries of time. It is a simple yet fascinating and mysterious concept. Now refers to a specific time, but the time it refers to is constantly changing.#2 The rate of time is not just a quandary of science fiction. It is difficult for humans to detect the difference between the flow of time when it moves at a slower rate and when it moves at a faster rate.#3 The concept of now is extremely difficult for humans to understand. We know what time is, but we can't describe it. We know that there is no past or future, but only three presents: a present of things past, memory; a present of things present, sight; and a present of things future, expectation.#4 The flow of time is an aspect of reality that the physicist sometimes seems inclined to neglect. However, there is hope that physicists will address the now conundrum in future theories.
