From Publishers Weekly

Nobel Prize-winning physicist Weinberg's quest for a final explanation of the laws of nature displays a scientist's sense of wonder and an artist's love of beauty.
Copyright 1993 Reed Business Information, Inc.

From Library Journal

In his celebrated book The First Three Minutes (Basic, 1977; 1988, reprint) Nobel laureate Weinberg wrote the ominous and oft-quoted remark "The more the universe seems comprehensible, the more it seems pointless." This book can be seen as his response to that remark after 15 years of reflection and scientific progress. Weinberg writes with great hope and clarity about the possibility that science can find a universal theory uniting the laws of nature into a single statement that is mathematically, philosophically, and aesthetically complete. His writing is technical in places, and some of the first-person narratives come off as less than humble, but overall Weinberg offers excellent insights on how such a theory could be realized and what it would mean. Especially engaging are his chapters, "Beautiful Theories" and "What About God?" Other books have been written on this subject (e.g., Paul Davies's Superforce , LJ 11/15/84; John Barrow's Theories of Everything , Oxford Univ. Pr., 1991; and Barry Parker's Search for a Supertheory , Plenum, 1987), but Weinberg's is likely to have the highest demand. Highly recommended.

Ce commentaire fait r�f�rence � cette �dition : Dreams of a Final Theory (Broch�)

Steven Weinberg is one of twentieth century's greatest theoretical physicists. He is one of the codiscoverers of the Electroweak Theory, an important piece of the puzzle that describes all of the fundamental forces of nature. He is also a very prolific writer, with several important textbooks and a few books that aim to popularize Physics and make it accessible to the general audience. The theme of this book is the long standing problem in Physics, and that is the one of unification of all forces under a single set of laws. Weinberg is as big of an authority on this subject as they come, as he has contributed and worked on various aspects of unification throughout his professional career. In this book he tries to explain what exactly is meant by "Final Theory." He is equally critical of opponents of this approach to science who deride it as overly reductionist, as he is of those who think that the discovery of final laws will in some way be the end of science. In some sense he is staking a middle ground between these two extremes.

This book was written in the years when the prospect of building the Superconducting Super Collider (SSC) was still tenable. SSC was supposed to be the largest particle collider in the world, and had it became operational it would have provided new data and insights into the mysteries of fundamental Physics. Or so we believed. Weinberg was one of the most prominent scientific proponents of this project, and he testified often in US Congress in its favor. Many of those encounters with politicians are discussed in this book. They provide a valuable and fascinating insight into how "big science" gets done. For one thing, scientific viability and value of any given project is only one of the important criteria that are considered when the pricetag for a project exceeds the entire budget of a small country. In the end SSC did not get the funding, and for better or worse our search for the ultimate laws of nature has since been almost exclusively a theoretical endeavor. This may change with the advent of Large Hadron Collider (LHC) in Switzerland, which is supposed to start taking data any moment now.

Throughout this book Weinberg touches on many philosophical themes, which in some sense is inevitable when one discusses such a vast topic as the ultimate theory of nature. Weinberg is rather dismissive of philosophical and religious considerations. This may be respectable insofar as his intellectual honesty is concerned, and we as readers at least know where he is coming from. However, the vast majority of people hope to understand the questions of the ultimate meaning in broadly philosophical terms, and it would be useful if scientists who are the most invested in the search for the final theory would at least try to present that search in some more accessible categories. Especially if they hope to have the general public on board when it comes to funding exceptionally large scientific projects.
