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'streatment 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 andextends 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 therole 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 withquantum mechanics. Harvey Brown' s new interpretation of relativity theory will interest anyone working on these central topics in modern physics.

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.

A noted preacher, college administrator, and father of an "all-American" family- what more could a man want? But when God struck the match that set Harvey Brown ablaze, it ignited a passion for holiness and renewal in his heart that led him into a head-on encounter with the consuming fire of God. This true story of a Christian professional's quest for God will touch you and change you. Discover how a visitation of the Holy Spirit and the miracle of grace transformed one life- and allow Him to do the same in yours!
