5.0 out of 5 stars
String theory for the layperson, August 15, 2003
This review is from: Our Superstring Universe: Strings, Branes, Extra Dimensions and Superstring-M Theory (Paperback)
An excellent introduction to string theory and the ideas and the problems that led up to it. The book starts off with basic concepts of time, space, matter, and energy and then develops a timeline of the universe from the big bang onward to the present that incorporates these concepts and speculates on the ultimate fate of the universe using the ideas of dark matter and dark energy. In addition, Mr. Lewis goes into the fundamental incompatibility between quantum mechanics and general relativity at the atomic scale and how string theory might resolve this. He also puts forth a unique and (as far as I know) original idea on a possible afterlife and how string theory could be used to preserve essential information about a person's life (which the author calls humanessence) through the holographic principle. Mr. Lewis develops his ideas very logically and concisely and provides plenty of illustrations which clarify his explanations. As a bonus, he even provides a glossary at the end of the book for the beginner. I would strongly recommend this book to anybody who has an interest in science and ideas and who wants to be introduced to what may be the ultimate theory of our universe.

1.0 out of 5 stars
Not much real science in this booklet, October 31, 2004
This review is from: Our Superstring Universe: Strings, Branes, Extra Dimensions and Superstring-M Theory (Paperback)
The pictures and tables are so poor in quality and printing that would have been wiser not to include them.
To make matters worst, the author attempts but completely fails to explain anything in this booklet.
There are websites built and maintained by amateurs and enthusiasts that are far better sources.
If you're looking for good books on M-Theory and related subjects, buy "The Elegant Universe" and "The Fabric of the Cosmos".

1.0 out of 5 stars
Grade-school prose, very short, yet padded, March 15, 2005
This review is from: Our Superstring Universe: Strings, Branes, Extra Dimensions and Superstring-M Theory (Paperback)
This little book has 128 pages of text. After some cosmology and particle physics, discussion of string theory commences on pages 53-57, conintuing on 73-102, 110-111, and 115-125, for a total of 48 pages. Subtract maybe another 25% for amateurish diagrams that do nothing but repeat the text, massive white space, and constant repetition, and you end up with about 36 pages of content on the subject of the title of this book.
I'm not sure who the target audience is for this work. It contains no mathematics beyond addition. It contains sentences such as this: "The nine planets of our solar system, in order of distance from the sun are: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto." Or: "Dividing by a number greater than one yields a smaller number." What do you think, maybe 5th graders?
The content is necessarily shallow, tossing out buzzwords, with no continuity, no real explanations. Branes are never actually defined. M-theory is never defined beyond being the theory that ties together all the other string theories. Somehow. I wonder what the "M" stands for.
