Summary: Stunning
Review: I was absolutly bowled over by the magnificent theorys that einstein portrayed in his study the shear magnitude of this piece of work left me quivering in my little cotton socks!i am absolutly thrilled that you have published this book and it has, quite frankly made my life more inriched and compleate!Its a jolly good read and being a proffessor of quantum Physics myself at cambridge university i can quite understand the complexity of the theorys produced in the stunning piece of work you are all jolly good chaps and i will be pleased if i could meet ip with the authors at next years boat race. thank you again. best wishes to all the boys at the boating yours faithfully Cha Cha Dimagio PhD gsa bof

Summary: To [e-mail] from Canada
Review: Though the book maybe was not a linguistically correct, the theory is. Einstein's theory has been tested and retested hundreds of times in the past eighty years and it has never once failed yet. Also, time and not just the clock, run slower as the observer speeds up. Experiments performed with atomic clocks; one being on earth and the other flown on a rocket ship show that. Each clock uses the same radiactive element that has a known decay rate. The one that is flown on a rocket or spaceship is space runs slower than the one on earth, in other words the element decays slower than the one on earth.

Summary: Why can't I get a banana milkshake in this damn country?
Review: I fell hurt, the monster towering above me, and I began to wonder why I don't like Mondays. Anyway I was suprised at the story about the Rabbi and his gerbil, who would have thought. Mr Einstein may be a genius, but he still has my laundry ticket from 1937, and I need that smoking jacket back.

Summary: If you don't already know the theory, don't bother...
Review: I hate to be the only one to not give the book "5 stars", but this is simply not the best book to buy if you want to learn the theory of relativity. The book is certainly worthwhile if you want something simply because it was written by Einstein, but God bless him, the old guy just couldn't put the idea accross as well as many modern authors. Maybe something is just lost in the translation, I don't know...

Summary: ABSOLUTE GENIUS
Review: The ideas may be hard to comprehend at times, but this work illuminates the real genius of Albert Einstein. If for nothing else this read allows you to get into the mind of a genius and see how he thinks. Definately worth while.

Summary: For science curious people w/a slight mathematics background
Review: An interesting and in-depth view of relativity. A slight mathematics background is very helpful with understanding some of the equations. The concept is clear and well articulated. It leaves you wanting a deeper knowledge of physics and Einstein.

Summary: A masterpiece written by a genius.
Review: The author of the theory of relitivity offers a clear explination of this complicated concept.All mathematical and technical aspects were clearly defined.Anyone interested and attentive could easily understand this book.Although short in length,it requires the reader to ingest the information slowly in order to obtain its full value.I would not recommend this book to anyone who has not graduated high school.

Summary: A staple of physics
Review: What can you say about einstein's relativity? well a lot. Einstein spearheaded the revolution of physics with his annus miribalis (1905) papers. You can't study physics without reading this book and taking in its profound effect on the universe as we know it.

Summary: Best description I have ever read on this subject
Review: This is a book writtenby someone who knows his subject and knows how to explain it in simple terms. If you want to do the math its in the back in appendicxes (there are some awful typos in the Lorentz transform appendix but not so bad you can't work out where the missing x is and that the gamma is really lambda).

But don't be put off by that. This is the best book to start with. By far.

Summary: Einstein had a language problem.
Review: I believe Einstein had a language problem. As an example, please pay attention to his demonstration of relativity of simultaneity. He mixed up [seeing by the observer] with [occurrence at the origin]. Therefore Einstein had no right to say that the two events did not occur simultaneously when the observer did not [see] them simultaneously. Let us say, we saw an explosion(A) of a star in 1998, and it was recorded that there was another explosion (B) many years ealier. An observer on earth could only say that he saw B earlier and A later; he could not say B exploded earlier and A later; nor could he say B and A did not explode simultaneously. Einstein's demonstration of his relativity of simultaneity was therefore neither convincing nor fundimentally sound. Einstein's language problem could also be seen in his free switch between the words [clock] and [time]. A clock may and can slow down, but can time slow down? Unless we get this language problem cleared up I believe Einstein's theory will remain controversial.
