Physical Relativity explores the nature of the distinction at the heart of Einstein's 1905 formulation of his special theory of relativity: that between kinematics and dynamics. Einstein himself became increasingly uncomfortable with this distinction, and with the limitations of what he called the 'principle theory' approach inspired by the logic of thermodynamics. A handful of physicists and philosophers have over the last century likewise expressed doubts about Einstein's treatment of the relativistic behaviour of rigid bodies and clocks in motion in the kinematical part of his great paper, and suggested that the dynamical understanding of length contraction and time dilation intimated by the immediate precursors of Einstein is more fundamental. Harvey Brown both examines and extends these arguments (which support a more 'constructive' approach to relativistic effects in Einstein's terminology), after giving a careful analysis of key features of the pre-history of relativity theory. He argues furthermore that the geometrization of the theory by Minkowski in 1908 brought illumination, but not a causal explanation of relativistic effects. Finally, Brown tries to show that the dynamical interpretation of special relativity defended in the book is consistent with the role this theory must play as a limiting case of Einstein's 1915 theory of gravity: the general theory of relativity. Appearing in the centennial year of Einstein's celebrated paper on special relativity, Physical Relativity is an unusual, critical examination of the way Einstein formulated his theory. It also examines in detail certain specific historical and conceptual issues that have long given rise to debate in both special and general relativity theory, such as the conventionality of simultaneity, the principle of general covariance, and the consistency or otherwise of the special theory with quantum mechanics. Harvey Brown' s new interpretation of relativity theory will interest anyone working on these central topics in modern physics.

BL Contains a hitherto untranslated paper by Einstein. The vacuum is fast emerging as the central structure of modern physics. How is this possible? What is the vacuum concept, and why is it so important? This collection brings together philosophically-minded specialists who engage these issues in the context of classical gravity, quantum electrodynamics, and the grand unification programme. The vacuum emerges as the synthesis of concepts of space, time, and matter; in the context of relativity and the quantum this new synthesis represents a structure of the most intricate and novel complexity. The Philosophy of Vacuum is unashamedly a project in metaphysics. The science of our time has transformed the concepts of space and time and of force and matter, yet the philosophy of Bohr and his school has found small purchase on the contemporary concerns of physics, and there are few guidelines to be found within the empiricist tradition of contemporary philosophy. However slippery the conundrums of metaphysical realism, the message of contemporary science remains the same: concepts and heuristics are grounded in consideration of what exists in the world. Here, then, is a work in modern metaphysics, in which the concepts of substance and space interweave in the most intangible of forms, the background and context of our physical experience: vacuum, void or nothingness.

Quantum field theory is not only one of the most rapidly developing areas of contemporary physics, but it is also full of problems of great theoretical and philosophical interest. This collection discusses quantum field theory from a wide variety of standpoints. The contributors explore its mathematical structure extensively and work through its metaphysical and methodological implications in detail. The contributors are Michael Redhead, James T.Cushing, Robert Weingard, Rom Harre, Paul Teller, Gordon N.Fleming, Tian-Yu Cao, Ray F.Streater and Simon Saunders.

Forgiveness is simple, but not easy. Many Christians have heard that they are forgiven, but still feel like there is a shadow cast over their lives. Others have difficulty realizing the freedom God offers through forgiveness. Using a conversational and straightforward tone, Dr. Harvey R. Brown, Jr. introduces the Christian concept of forgiveness and outlines how this powerful idea can change your life for the better. God's grace and forgiveness are not just at the moment of conversion. They should become part of your every day life as you learn to forgive family, friends, enemies, past hurts, and yourself as well.
