More About the Author

Paul Davies is an internationally acclaimed physicist, cosmologist, and astrobiologist at Arizona State University, where he runs the pioneering Beyond Center for Fundamental Concepts in Science. He also chairs the Search for Extraterrestrial Intelligence Post-Detection Taskgroup, so that if SETI succeeds in finding intelligent life, he will be among the first to know. The asteroid 1992OG was officially renamed Pauldavies in his honor. In addition to his many scientific awards, Davies is the recipient of the 1995 Templeton Prize--the world's largest annual prize--for his work on science and religion. He is the author of more than twenty books, including The Mind of God, About Time, How to Build a Time Machine, and The Goldilocks Enigma. He lives in Tempe, Arizona.

5.0 out of 5 stars "ingenuity and subtlety . . . unity, order and harmony", November 28, 2005

Noble physics laureate Abdus Salam calls this book "heady stuff" and says, "Davies has established himself as one of the most felicitous writers on physics at the frontier."

Over the years I've become something of a Paul Davies connoisseur, having read many of his books. Among noted scientists writing popularizations, Davies is the reigning gold-standard. This is the best of his early works. When it was published in 1984, Davies had achieved some acclaim for his previous book 'God and the New Physics' but 'Superforce' is a far superior work (GatNP was perhaps his worst book). Superforce is not only one of Davies best books, in some ways it's one of the best physics popularizations ever published. Although the thesis is the deepest [expected] 'law' of nature (the superforce, supersymmetry, unified field, ToE, GUT, call it what you will) the first three chapters are as concise an explanation of quantum theory as a novice could hope for. If you don't get a glimpse of the "weird" quantum world from the first 50 pages, you probably never will ("The apparently concrete matter of experience dissolves away into vibrating patterns of quantum energy"). Perhaps the most significant consequence of the quantum theory is the insight that mind is a fundamental component of our world, not, as some had expected, a secondary phenomenon arising from mere mechanism. And Davies' exposition has just begun.

With the groundwork established, Davies begins toward the heart of the matter in chapter four, exposing mathematical and gauge symmetries and the fascinating role of aesthetics, i.e., beauty, in nature (and thus in theoretical physics). Treated next are; the four supposedly fundamental forces, the particle "zoo" including messenger particles, QED, and the not-so-empty vacuum populated with "temporary particles whose visit is financed by the Heisenberg loan." And then a return to symmetry -- and hidden symmetries and symmetry breaking. Moving forward systematically, the going gets tougher. With electricity, magnetism, and the weak nuclear force mathematically combined, the next force to be included in the expected 'superforce' is the strong (glue) force, and this presents several problems, to put it mildly. Davies discusses the challenge of developing gauge field theories for quarks and gluons and how it has been met by QCD (quantum chromodynamics). With the expectation of a GUT now explained, what remains is to look at the contending variations (to explore the precise fit of QCD in a GUT by way of direct experiment, "we should have to build an accelerator larger than the solar system", to experimentally establish a GUT complete with gravitation, we would have to construct an accelerator larger than our galaxy!). Obviously mathematics is now the only tool available.

Having already explained how the quantum theory has dispelled prospects for a strict reductionism wholly succeeding, Davies now develops the argument (chapters 9 - 12) that a single physical theory will eventually explain, yes -- everything (sort of). If this apparent turnabout has your head spinning, well, Davies isn't finished. He goes on finally to explain that such a theory of "everything," astounding and useful as it may be, has little, if any, hope of actually being an explanation of everything (chap 14). Like Stephen Hawking and perhaps most theoretical physicists in 1984, Davies anticipated a more or less completed Grand Unification Theory within a few years.

When Davies wrote this book it was cutting edge stuff, reporting and analyzing very recent developments. Of course, a few things are now a bit dated: Davies (in 1984) expected that the universe was 18 billion years old, while something like 12 to 13 billion is now thought. And at one point he says that 'evidence' indicates "Earth is a typical planet." This was a particularly popular view 20 years ago, but today I think Davies view is rather different, amenable to better and more recent data (see, for example, the books 'Rare Earth' and 'The Privileged Planet'). But most of the science here is still accurate (and "literally boggles the mind"). The discussion of the relationship of thermodynamics to the 'rolled up' dimensions of string theory in the context of the early universe is excellent.

In the concluding chapter, Davies asks if there is a 'cosmic plan' and if so what is then implicit. "The new physics and the new cosmology hold out a tantalizing promise; that we might be able to explain how all the physical structures in the universe have come to exist . . . as a result of natural processes. . . Nevertheless, though science may explain the world, we still have to explain science. The laws which enable the universe . . . seem themselves to be the product of exceedingly ingenious design. If physics is the product of design, the universe must have a purpose, and the evidence of modern physics suggests strongly to me that the purpose includes us." All in all, this is one of Davies' best books. Five solid stars, even if a final GUT is not as closely anticipated as it was in the 80's, even if not quite perfect, and even after 20+ years.

5.0 out of 5 stars fabulous populariser of physics, September 4, 2004

By

This review is from: Superforce (Paperback)

This is an astonishingly lucid and consistently fascinating look at the scientific search for the single force that is purported to unite all the forces of nature - the reader gets a review of the known forces as well as the new ideas emerging from chaos and complexity theories. Davies is one of the great popularisers who NEVER indulges in hype or wild speculation, but instead sticks to the science. While his books may seem austere, they are clearer and more precise than a myriad of other science writers, who puff up meagre results with pseudo-science.

Warmly recommended.

4.0 out of 5 stars a capable and ambitious explainer, January 17, 2011

By 

Nigel Kirk (Canberra, Australia) - See all my reviews

This review is from: Superforce (Paperback)

Davies has managed a masterly survey of modern physical theory. He covers a lot of area, so the treatment of some topics is brief. Always the teacher, he props up concepts with good models and examples. Davies has, in this and other books, registered as one of the best explainers of quantum concepts. Superforce includes an engaging description of the importance of mathematics as the language of physics. It also explains why some slightly opaque terms such as `fields' and energy' are useful in explaining physics mathematically.
