This collection of essays by leading philosophers of physics offers philosophical perspectives on two central elements of modern physics, quantum theory and relativity. The topics examined include the notorious "measurement problem" of quantum theory and the attempts to solve it by attributing extra values to physical quantities, the mysterious non-locality of quantum theory, and the philosophical aspects of the search for a theory of quantum gravity. Together the essays represent some of the most recent research in philosophy of physics, and break new ground within the philosophy of quantum theory. "This collection of nine essays by leading philosophers of physics offers philosophical perspectives on two of the central elements of modern physics, quantum theory and relativity." Book News "The authors are well acquainted with both philosophical argumentation and mathematical formalism, and following the lead by Professor Redhead, they combine these in intricate and suggestive ways...I enjoyed reading the book immensely...[it] is really what the title promises: a guide from physics to philosophy." Contemporary Physics "This admirable volume...is a good place to find out what contemporary philosophers of physics regard as important problems. It is good, not just because of the breadth of topics discussed, and the fact that, without exception, the articles are well written and stimulating, but because some contain important results I have not seen elsewhere." Studies in History and Philosophy of Modern Physics "...this is a fine collection of articles....They reveal the remarkable depth of knowledge of current philosophers of science..." Philosophy in Review These essays by leading philosophers of physics offer philosophical perspectives on quantum theory and relativity.
