Beyond Einstein: The Cosmic Quest for the Theory of the Universe

I really liked this book. It found it easier to understand (and less gee-whiz) than Brian Greene's The Elegant Universe (paperback and CD). Kaku and his co-writer presented a very clear description of what hyperspace would look like to four-dimensional creatures such as ourselves. (This was the first clear layman's description I have read.) I only wish I understood better the quantum mechanics that "vanquished" Newton's and Einstein's propositions about gravity in very small spaces; perhaps some drawings would have helped. In addition, perhaps a chart or diagram of basic sub-atomic particles would have helped. Nevertheless, I was intrigued by the book. Thompson's co-writing makes it intelligible to lay persons such as myself. The one element that Kaku leaves out is whether string or superstring theory is "testable." In dimensions of the size of 10^-18 cm, perhaps we cannot really make testable predictions, as Greene asserts in his book and CD.

If you have even the slightest interest in theoretical physics, astronomy, or cosmology, READ THIS BOOK. Michio Kaku continues with "Beyond Einstein" in the proud tradition of its predecessor, "Hyperspace;" I read it as a sophomore in high school and couldn't put it down, and "Beyond Einstein" was no different. No prior knowledge of physics or mathematics is assumed; all you need is curiosity about how the world around you works. It is well-written and easy to understand, with just enough history to set the reader up for the science. This book will absolutely DAZZLE YOU!

As an engineer I like to keep up with things, plus I've always enjoyed Physics. This book easliy brings you up to date with modern Physics, and has many interesting stories about many of the great men and women in Science. It doesn't grind you through lengthy equations and it doesn't cost $50. Highly recommended.

This book was extrememly well written, I am 15 years old and understood everything clearly. A must for anyone interested in physics and to what regions physics is heading into the future.

Although not as well written as, 'Hyperspace,' Michio Kaku has put complicated aspects and terms of cosmology and quests for unified field theories into a simple, easy to follow book by using many similies and metaphores. The book totally avoided explaining the concept of superstring theory, but instead it gave a lot of information that lead up to it. Nevertheless, I thoroughly enjoyed reading Dr. Kaku's new book because it gave lots of information about different theories that lead to superstring theory, such as: special relativity, general relativity, Maxwells theories, Newtons theories etc. The book also grasped the concept of understanding the beginning of the universe before and after the big bang, although not going into it in much scientifical detail. However, the big bang is totally theoretical and hard, infact impossible to explain omnisciently. The book has some diagrams; resultingly, making the comprehension of some ideas much easier. Dr. Kaku is indeed capable of better work, (not that this isn't good) he is by far one of the best autors of the understanding of space, in my opinion the only better autor is Steven Hawking himself. Dr. Kaku is an inspirational role model to me and I hope others agree. His books can be read by anyone from elementary school students to top physicicists, due to the simplification of the terms of thought. The only people that I don't recomend this book to are the people totally interested in the science and detailed decriptions of superstring theory. Otherwise a Must to read!!!!!!!!!!!!!
