I read this book 25 years ago, yet it remains the single clearest explanation of Einstein's theories, particularly the theory of relativity, that I have ever read. Of particular note, the explanations usually employ the same mental pictures that were used by Einstein to develop the theories, e.g., an elevator moving through space, with no reference points. This is a particularly appropriate book to give to a high school student who has an interest in science but who may not yet have progressed through the basics of physics. I read it at that age, and it sparked an interest in physics, particularly light theory, that exists to this day

7 years ago. I went to a small section of the science-translate books. I got this book in Thai version (Thank you for whom translate this). Up to now. this is one of the books I re-read most frequently. I might not smart enogh though I will get new idea from reading it every time. This book contain a simplified idea and give you the concept of Einstein most acknowledge theory. It's not purely science but include some kind of philosophy which let me think along whether it's true or not. Though it is still very readable and understandable.

I feel that this book is a must for any home library. If you are experienced in physics, this book is extremely interesting because it delves deaply into the philosophy that brought Dr. Einstein to his great accomplishments. For those that have little knowledge of relativity, the universe, and quantum matters it offers a great introduction with a minimum of complex math. A simple way to understand how Dr. Einstein changed the entire universe. I have studied Albert for years. This is the first time I have read anything that gave me such an insight to his personality and thought processes. HONESTLY, the best book I have ever read.
