While quantum theory has been used to study the physical universe with great profit, both intellectual and financial, ever since its discovery eighty-five years ago, over the last fifty years we have found out more and more about the theory itself, and what it tells us about the universe. It seems we may have to accept non-locality - cause and effect may be light-years apart; loss of realism - nature may be fundamentally probabilistic; and non-determinism - it seems that God does play dice! This book, totally up-to-date and written by an expert in the field, explains the emergence of our new perspective on quantum theory, but also describes how the ideas involved in this re-evaluation led seamlessly to a totally new discipline - quantum information theory. This discipline includes quantum computation, which is able to perform tasks quite out of the range of other computers; the totally secure algorithms of quantum cryptography; and quantum teleportation - as part of science fact rather than science fiction. The book is the first to combine these elements, and will be of interest to anybody interested in fundamental aspects of science and their application to the real world.

This book offers a comparative analysis of the experiences, responses, and adaptations of people to climate variability and environmental change across the Americas. It foregrounds historical ecology as a structural framework for understanding the climate change crisis throughout the region and throughout time. In recent years Indigenous and local populations in particular have experienced climate change effects such as altered weather patterns, seasonal irregularities, flooding and drought, and difficulties relating to subsistence practices. Understanding and dealing with these challenges has drawn on peoples’ longstanding experience with climate variability and in some cases includes models of mitigation and responses that are millennia old. With contributions from specialists across the Americas, the volume will be of interest to scholars from fields including anthropology, archaeology, geography, environmental studies, and Indigenous studies.

This book presents an account of all aspects of Einstein 's achievements in quantum theory, his own views, and the progress his work has stimulated since his death. While some chapters use mathematics at an undergraduate physics level, a path is provided for the reader more concerned with ideas than equations, and the book will benefit to anybody interested in Einstein and his approach to the quantum.

John Stewart Bell (1928-1990) was one of the most important figures in twentieth-century physics, famous for his work on the fundamental aspects of the century's most important theory, quantum mechanics. While the debate over quantum theory between the supremely famous physicists, Albert Einstein and Niels Bohr, appeared to have become sterile in the 1930s, Bell was able to revive it and to make crucial advances - Bell's Theorem or Bell's Inequalities. He was able to demonstrate a contradiction between quantum theory and essential elements of pre-quantum theory - locality and causality. The book gives a non-mathematical account of Bell's relatively impoverished upbringing in Belfast and his education. It describes his major contributions to quantum theory, but also his important work in the physics of accelerators, and nuclear and elementary particle physics.

James Clerk Maxwell (1831-1879) had a relatively brief, but remarkable life, lived in his beloved rural home of Glenlair, and variously in Edinburgh, Aberdeen, London and Cambridge. His scholarship also ranged wide - covering all the major aspects of Victorian natural philosophy. He was one of the most important mathematical physicists of all time, coming only after Newton and Einstein. In scientific terms his immortality is enshrined in electromagnetism and Maxwell's equations, but as this book shows, there was much more to Maxwell than electromagnetism, both in terms of his science and his wider life. Maxwell's life and contributions to science are so rich that they demand the expertise of a range of academics - physicists, mathematicians, and historians of science and literature - to do him justice. The various chapters will enable Maxwell to be seen from a range of perspectives. Chapters 1 to 4 deal with wider aspects of his life in time and place, at Aberdeen, King's College London and the Cavendish Laboratory. Chapters 5 to 12 go on to look in more detail at his wide ranging contributions to science: optics and colour, the dynamics of the rings of Saturn, kinetic theory, thermodynamics, electricity, magnetism and electromagnetism with the concluding chapters on Maxwell's poetry and Christian faith.

This book gives a readable non-mathematical account of the upbringing, education and academic achievement of John Stewart Bell, the celebrated physicist from Belfast, who was born in 1928. Bell has become famous for what he described as his 'hobby', analysing the fundamental aspects of quantum theory, where he clarified a long-standing debate between the two most important figures of twentieth century physics, Albert Einstein and Niels Bohr, and showed that, contrary to belief over the previous thirty years, quantum theory could be supplemented with extra 'hidden variables'. His crucial 'Bell's Theorem' or 'Bell's Inequalities' demonstrated a contradiction between quantum theory and local causality. This relation has been tested with increasing rigour over the next years, and quantum theory has triumphed. His ideas were also important in the development of quantum information theory, which covers quantum computation, quantum cryptography and quantum teleportation. The book covers his earlier work at Harwell, where he worked on the design of accelerators, making extremely important contributions to the physics of strong focussing. He later moved to CERN in Geneva where he carried out highly significant work in the fields of elementary particles and quantum field theory. It also covers some details of Bell's personal life, including his marriage while he was at Harwell to Mary Ross, who also worked in the physics of accelerators, and also describes his career decade by decade, and sums up his importance to twentieth-century physics.

Quantum theory, the most successful physical theory of all time, provoked intense debate between the twentieth century's two greatest physicists, Niels Bohr and Albert Einstein. Quantum information theory has emerged from intensive study of the structure and interpretation of quantum theory to become one of the fastest growing areas of twenty-first century science. This second edition has been extensively revised and updated to cover recent developments, including the findings of papers published since the well-received first edition. A substantial new chapter is devoted to the development and structure of quantum information theory. Developments in the experimental and theoretical study of Bell's Theorem are also covered in detail, and the accounts of ongoing work have been brought up to date. A fascinating account of the development of quantum theory, this book will appeal to anyone with an interest in the fundamental questions of physics, its philosophy and its history.
