What one reviewer at amazon said about Relativity: The Special and the General Theory:
This book is truly a scientific gem. Not only did the brilliant Einstein envision the theory of relativity, but he also felt compelled to inform non-scientists by writing this "less" technical explanation of his theory. The book's section on Special Relativity is not too difficult to grasp. However, having some basic understanding of algebra and classical mechanics is helpful. On the other hand, the section on General Relativity is quite profound, requiring the reader to imagine new concepts of space and time that are alien to one's sense of reality. Indeed, I had to read this section several times and I'm still not sure if I completely understand it. However, this is more of a function of my imagination skills rather than Einstein's literary abilities. For he uses an abundance of familiar terms and analogies to simplify the understanding of some of the more "unusual" implications of General Relativity. I would not recommend this book to someone averse to technical subjects. However, I do recommend it to those wishing to learn the basics of relativity theory.
