This snapshot of the future of physics comprises contributions from recognized authorities inspired by the pioneering work of John Wheeler. Quantum theory represents a unifying theme within the book, as it relates to the topics of the nature of physical reality, cosmic inflation, the arrow of time, models of the universe, superstrings, quantum gravity and cosmology. Attempts to formulate a final unification of physics are also considered, along with the existence of hidden dimensions of space, hidden cosmic matter, and the strange world of quantum technology.

Anybody who is not shocked by quantum theory has not understood it. Niels Bohr's dictum bears witness to the bewildering impact of quantum theory, flying in the face of classical physics and dramatically transforming scientists' outlook on our relationship with the material world. In this book Paul Davies interviews eight physicists involved in debating and testing the theory, with radically different views of its significance.

A comprehensive review of gravitational effects in quantum field theory. Treatment is general, but special emphasis is given to the Hawking black hole evaporation effect and to particle creation processes in the early universe.

This is a new edition of Paul Davies' very highly regarded text on high-energy particle physics aimed at the scientifically educated general reader. Since the appearance of the first edition in 1979 there have been many major developments in the field, and the author has taken this opportunity to bring the text completely up to date. Paul Davies includes details of one of the most significant of these developments, the experimental discovery in 1983 of the W and Z intermediate vector bosons, and discusses the implications for the eventual unification of the four forces of nature. In addition to this, the discovery of the top and bottom quarks, the details and predictions of modern grand unified theories (GUTs), and the application of the results of high-energy physics to studies of the very early universe are all included.

Geared to the layperson, a clear, concise, non-mathematical explanation of the "Theory of Everything" and its profound implications is followed by transcripts of interviews with most of the physicists involved in its development.

In The Accidental Universe renowned expositor Paul Davies grapples with the most fundamental questions of all. What is our purpose and the purpose of the universe? Are both an accident of nature? Paul Davies guides us through the mysterious coincidences underlying the structure and properties of the universe we inhabit. He sets out the intriguing hypothesis that the appearance of the universe and its properties are highly contrived. Paul Davies gives a survey of the range of apparently miraculous accidents of nature that have enabled the universe to evolve its familiar structure of atoms, stars, galaxies and life itself. This remarkable book concludes with an investigation of the anthropic principle, which postulates that much of what we observe around us is a consequence of the presence of observers in the universe. This thesis of a cosmic biological selection effect is fiercely debated among scientists and is here set out clearly for a general readership.
