The Theory of Everything

The Theory of Everything

Stephen Hawking's The Theory of Everything is a short book that can act as an introduction to the subjects of cosmology raised by modern science, but the book is only that; I preferred his Brief History of Time to this work because it was longer, more detailed, and covered more ground. If you are looking for a very basic introduction to the current thinking of astrophysicists, this is a good book; if you really want to wrestle with the subject at length, you should buy a Brief History of Time, or one of Paul Davies works, such as About Time. If you are looking for a good lecture series on physics, Richard Feynman's Six Easy Pieces and its sequel, Six Not So Easy Pieces is really the finest of this genre. That being said, the book does a good job in outlining the basic subject matter, discussing the development of the Big Bang theory, and the implications of both the general theory of relativity and quantum physics on the formation of the universe. Hawking is at his best when discussing singularities -- the points of the universe, such as black holes, where the laws of physics break down. --By D. W. Casey on June 27, 2002

This is a collection of seven related lectures by Hawking originally published in 1996 under the title, The Cambridge Lectures: Life Works. He does not cover as much ground here as in did in A Brief History of Time, but what he does cover he does so in a charming and engaging style. There are some few statements here that could be interpreted as less than modest--although not by me--and a mistaken prediction or two, which may be a reason that Hawking is not pleased with this book's publication. He might also object to the title, since neither a "Theory of Everything" nor a conclusive answer to the origin and fate of the universe are presented. However, Hawking does address these questions, and his expression is interesting to read and has the agreeable characteristic of being laconic. There are no equations in the book, no mathematics as such, and everything is explained in language that would be intelligible to a high school student. There are the usual droll Hawking jokes about God and His intentions, facetious, epigram-like understatements (I have done a lot of work on black holes, and it would all be wasted if it turned out that black holes do not exist. p. 66) and witty asides about the convergence of politics on physics, as when he mentions a particle accelerator the size of the Solar System that "would not be funded under current economic conditions." --By Dennis Littrell on March 23, 2003
