The 9th Conference, held September 1990, was organized around four main themes: general relativity and classical theories of gravitation, relativistic astrophysics and cosmology, experimental and observational gravitation, and supergravity and quantum gravity. Some 70 papers (both invited and contributed) are collected. No index. Acidic paper. Annotation copyrighted by Book News, Inc., Portland, OR

This is the proceedings of the 9th conference in this series. In addition to papers presented at the conference proper, it contains some papers delivered at Peter G Bergmann's 75th Birthday meeting (Capri, 24 Sept 1990). Among the subjects covered are cosmology and astrophysics, both theoretical and experimental.

This book is for physicists, historians and philosophers of physics as well as students seeking an introduction to ongoing debates in relativistic and quantum physics. This title covers the recent debates on the emergence of relativity and quantum theory. It includes chapters with an introductory character, comprehensible to students and science teachers. It strengthens the bonds between the communities of scientists, historians, and philosophers.
