This book was originally published in 1980. Theoretical physics makes extensive use of models to test and develop intuition. This monograph seeks to provide an introduction to high-energy model making. Its aim is to explain the basic ideas in a form accessible to graduate students and other readers who have acquired a first-hand knowledge of quantum field theory and basic particle physics, including the elements of Regge theory. It describes major calculational techniques together with sufficient physical applications to illustrate their utility. No attempt has been made to be encyclopaedic, for an exhaustive treatment of every application would have created a volume too large for the simple pedagogic purpose intended.

Certain interactions, such as nuclear forces and the forces of ‘high-energy’ physics, which arise in the theory of elementary particles, cannot be described successfully by quantum field theory. Considerable interest has therefore centred on attempts to formulate interactions between elementary particles in terms of the S-Matrix, an operator introduced by Heisenberg which connects the input and output of a scattering experiment without seeking to give a localized description of the intervening events. In this book four authors, who are together responsible for many of these developments, set out a theory of the S-Matrix starting, as far as possible, from physically plausible assumptions and investigate the mathematical consequences. The least understood of these assumptions is the vital postulate of analyticity; much insight can however be gained into its working by a study of the Feyman integrals and the book describes what is known about their analytic and high energy properties. Originally published in hardback in 1966.

The development of kenotic ideas was one of the most important advances in theological thinking in the late twentieth century. In The Work of Love eleven foremost theologians and scientists discuss the kenotic view of creation, exploring the implications of this controverial perspective for Christian doctrine and the scientific enterprise generally. The authors' backgrounds are diverse-ranging from systematic theology to neuropsychology-yet each agrees in seeing creation as God's loving act of divine self-restriction. The key concept, kenosis ("self-emptying"), refers to God's voluntary limitation of his divine infinity in order to allow room for finite creatures who are truly free to be themselves. This engaging formulation of God's creative work challenges the common conception of God as a divine dictator and provides a more satisfying response to the perplexing problem of evil and suffering in the world. The fruit of discussions sponsored by the John Templeton Foundation, these stimulating chapters bring a needed interdisciplinary approach to this weighty new trajectory in Christian thought.

John Polkinghorne dares to ask the questions that would seem to be too dangerous to ask--and he comes up with some answers which are deeply satisfying to both mind and heart.

Although now an Anglican priest and head of one of the prestigious colleges in Cambridge University, John Polkinghorne has spent most of his adult life working as a theoretical physicist. He is therefore uniquely qualified and frequently called upon to set forth the relationship between science and theology in a way that takes the two disciplines seriously. Polkinghorne argues that the habits of thought that are natural to the scientist are the same habits of thought that can be followed also in the search for a wider and deeper kind of truth about the world. He calls this bottom-up thinking, that is starting not with general principles but with the particularity of experience, and then asking what is sufficient to explain the phenomena and give an understanding of what is going on. Portions of this book were delivered as the Pascal Lectures at the University of Waterloo (1992) and as the William Belden Noble Lectures at Harvard University (1993). The first half of the book seeks to establish an acceptable meeting point for science and religion. The second half looks at some specific theological issues approached creation, the role of chance, God s engagement with time, the anticipation of a destiny awaiting humanity beyond death, and the end of the universe. John Polkinghorne is President of Queens College in Cambridge University. He is the author of many books, including Reason and Reality, published by Trinity Press International.

The dialogue between science and theology has grown to mammoth proportions over the past decade. These two disciplines search continually to discover their common ground. Each discipline is anxious to warrant its own truth claims concerning the nature of reality and the nature of God. In order to be fruitful, such dialogue, argue the authors of this collection, should focus on one subject. In this volume, 16 scientists and theologians contend that eschatology provides a common concern for both theology and the sciences. Eschatology, they claim, will help clarify and cultivate the differences between truth claims in both fields. Moreover, a focus on eschatology offers an opportunity to examine the reasons people can be hopeful and optimistic even in the face of physical death and the finitude of the universe. Included in this provocative collection are essays on eschatology and the natural sciences, eschatology in cultural sciences and ethics, eschatology in the biblical tradition, and eschatology and theology. John Polkinghorne is the president of Queens College, Cambridge and the author of Reason and Reality (Trinity) and Serious Talk: Science and Religion in Dialogue (Trinity). Michael Welker teaches at the University of Heidelberg. Contributors to the volume include William R.
