Summary: Delightfully Enlightening.
Review: For anyone who wishes to gain a deep and true understanding the meaning of General Relativity's space-time, this a book to read. And that this understanding is gained with mathematics no more sophisticated than high school geometry and algebra tells you that the author is not only a master, but also a superb expositor, of this subject. A highschooler having a passion for Physics to a Graduate Student struggling to "internalize" the meaning of her complex equations will be delightfully enlightened reading this book.

Summary: Verbal Description of General Relativity
Review: The author presents fundamental ideas of theory of relativity in a non-mathematical form using conversation approach to readers with little science background. The book is highly descriptive and the reader is bound to get bored since this is a discussion of about basic ideas about space and time using two-dimensional space-time diagrams. The first part of the book describes the notion of space and time in terms of Aristotelian and Galilean view points. The second half describes how the idea of spatial distance and elapsed time (interval) are incorporated into space time as geometrical entity. The author uses a general framework in this book for explaining general relativity. This is done by describing an event and assemble them into space-time (in a space-time diagram) and describe what is going-on in the physical world in terms of collection of events, and relationships between events is evaluated using measuring instruments such as light pulses and clocks. The intrinsic relationship between two events is described by interval (measured by physical experiences of observers). From the interval, one determines how light goes and how clock move and tick. The author eventually explains how equating intervals leads to relationship between 'real' physical measurements. The interval is a sort of misty thing that stands in the background and integrates into space-time. In the final chapter the author discusses an application of general relativity to understand the properties of blackholes: It is here that the readers appreciate the importance relativity. The reader must have patience to read this book and he/she must be prepared to read chapters 5 and 6 second and perhaps third time to understand the underlying concept. If you do not have patience you will be lost and you will dislike this book

Summary: Very simple introduction
Review: This book is not a college book on relativity. it is written for curious mind who wants to know something about the relativity and author gives a very layman introduction to it.It starts with space-time concept of Aristotelian, Galilean view and than slowly enters into relativistic view. A lot of space has been delegated to definition and explanation of the concept of Iterval and than jumps into physical meaning of the concepts. It is only as the author says from A to B and no more.

Summary: A Grand First Step. Well, maybe a quarter step..
Review: This still ranks as one of my favorite relativity books. There is virtually no math to speak of. Yet, the author in a very descriptive way, will take you from Aristotelian view to the Galilean view and finally to the relativistic paradigm. Concepts such as events, event horizons, interval etc. are explained quite beautifully. The idea of the interval and the physics and geometry of the same is shown in a most interesting way. The chapters are organized very well and the writing is very good. To follow the text a certain degree of concentration is required because the diagrams need to be checked as one proceeds. This text is quite suitable for junior high and high school students not to mention college graduates who wish to know something beyond the cursory in relativity theory. I happened to come across this book at a used bookstore in 1979. Very few of my friends were even aware of this book. It was one of those sleepers so much so that a while back this volume had gone out of publication. However, now it's back, thank God. If you want a non-technical but quite thorough peek into Special Relativity get this book. If you are one of those who would prefer a tad more math and a less wordy introduction go with James A. Smith's An Introduction To Special Relativity, published by Dover.
