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.
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 behavior 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.
Physical Relativity is an original, 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.
