Destined to be a timeless classic Introducing Time is one of the Introducing series most popular selections. For an Introducing book it is also one of the most detailed, thought provoking, wide-ranging and heady science volumes around. If you want to know anything about time then Introducing Time does just that and then some more, but be prepared for lots of difficult diverse thinking.
In most cases the first 100 pages will be more than enough for most people and the Introducing series could easily have made this book 200 pages long with that material alone but instead has condensed the opening philosophical thought on time into a shorter amount and goes straight into Einstein, relativity, lots on time travel and a great finish on entropy. Most of these topics are actually books in their own right such as Introducing Relativity and Introducing Einstein so Introducing Time really is good value for money.
If you are thinking about starting a collection of science titles from the Introducing series then you would do well to get this book or add it to your collection for two reasons. First of all, Introducing Time includes the best explanation of Boltzmann's statistical mechanics and entropy I have read anywhere. It could be worth it for that alone. You may not expect entropy to have such an impact on the topic of time and that can be a very nice surprise when reading that it does. The second is really just the breath of the coverage that time gets in this book. Even those who have read Stephen Hawking's `A brief history of time' will come away from this one with a whole lot more than thought possible.

This is far from an easy book but time is a detailed topic and should get the full treatment if it should be treated at all. For this reason Introducing Time is quite simply one of the most important and revealing books on something that people take for granted. It's the kind of book you come away with a mind full of awe. If Introducing Time doesn't change your worldview then nothing will.
a surprisingly in depth introduction to time Introducing Time starts off with Aristotle's view on time then goes on to talk about many philosophical and scientific views of time. It includes Newton's absolute time, Einstein's special and general relativity as they relate to time, including Godel Universes, and also Boltzman's statistical mechanics based view of time. All in all a lot of information in such a short book.
A highlight of the series Great book. By the time you get to the end, you'll know quite a lot about this topic and the whole theory, but you'll be pretty confused. Why confused? Because it's a hard topic to understand or interpret. And the book explains that as well as it can. But it sure will make you think.
Time is easy to understand, until you start to think about it. These authors did that, they thought about it Time is a concept that all humans have a fundamental grasp of. We all know that there is a direction to the events of our lives and that once an event happens, to the best of our knowledge it will always have happened. We break it down into units of years, days, hours, and minutes and in the last minute of some sporting events, tenths of seconds. However, when we really try to get a precise intellectual handle on it, time becomes fuzzy and it is very difficult to be precise. The passage of time is also relative to the situation; a few minutes in a dentist chair can appear to be much longer, yet a few hours with our true love can seem like minutes. In this book, Callender and Edney describe some of the attempts by scientists and philosophers to precisely define what time is. Some argue that to be logically consistent, time cannot exist. That of course seems absurd, whatever else we may know, at least locally, time does have an existence and a direction. Newton, Einstein, Godel and others have refined the concept, Einstein in particular demonstrated that the passage of time is slowed when the objects are traveling at high rates of speed. Although the authors do an excellent job using cartoons and other visual devices, the true nature of time is a difficult topic. Like the apparent fate of the universe, in the end, time simply comes down to an overall increase in entropy, for that is the way we recognize the passage of time. This is an excellent book about an apparently simple, yet very complex subject. Time is a subject that we all think we know, until we really start to think about it.
Proof that "Time" is interpretive, thus not understandable-- I purchased this book because I hoped to gain a deep or profound insight about Time from educated, intellectual minds. And while I did in fact achieve this goal, it was not thru the manner that I expected.
I support the entire "Introducing..." series by Totem because their illustrations along with genuine, serious educational content make the books highly appealing, attractive and inspiring. And this one was no exception -- in terms of doing its best to present, primarily chronologically, what informed minds from involved and associated fields had to say, or present as theory, about "Time." But -- and this is meant to have a dramatic impact -- BUT... it was through reading what these thinkers and scholars had to say about time that verified to me that nobody knows what it is. Which is a good thing; a great thing! To me this means that a little boy or girl living out in the middle of nowhere has just as much right -- and is equally "correct" -- in whatever they feel or suppose "time" is. After reading this book, I realized that nobody can 'know' what Time is, but rather they attempt to define it in ways, that when one looks at it clearly, should come to see as solely based on the way 'time' is measured. Again, time is not definable; it is open to interpretaion; one must be wary of definitions that purport to define, but really do nothing more than present notions based upon how 'time' is measured. A person who sees "time" as seconds, minutes, hours, days, months and years is no more correct than a person who experiences time as an independent, deeply-personal intuitive experience.
The best part of the book is the brief area where Einstein's theories of relativity are introduced. As for the rest, to this reader, it was truly great minds "mentally masturbating." The question is: Do these great minds know they're "m.m-ing" or do they truly believe they are offering a profound contribution to the study of Time?
But, in all fairness to the book, it was not until I read it that I came to understand what I have attempted to present here. And what I would like to say to any person wondering if they should read this book: Yes, do so; but be confident in whatever you get out of the experience, in terms of your idea of time, do know that you too are equally correct!
Nobody knows or understands time. It is open to interpretation. And that is what makes it a beautiful phenomenon. "Time" has not given its secrets over to any one.
