This is the only book to chart the history and development of modern probability theory. It shows how in the first thirty years of this century probability theory became a mathematical science. The author also traces the development of probabilistic concepts and theories in statistical and quantum physics. There are chapters dealing with chance phenomena, and current major mathematical theories, together with their foundational and philosophical problems. Among the theorists whose work is treated at some length are Kolmogorov, von Mises and de Finetti.

What can emission lines tell us about an astrophysical object? A workshop at the Space Telescope Science Institute was dedicated to address just this question - for a host of objects (including planetary nebulae and active galactic nuclei) across a broad range of wavelenghts (from the infrared through to gamma-rays). Sixteen review articles are presented in this volume. They provide an overview of technical data, techniques in and applications of the study of emission lines from a variety of objects.

This timely volume presents specially written articles by world experts at an international conference at the Space Telescope Science Institute. The goal of the meeting was to assemble physicists and astronomers working on all aspects of dark matter and theories of gravity. Topics covered include Nucleosynthesis, Hot Gas in Clusters, MACHOs, WIMPs, Rotation Curves, Gravitational Lensing Neutrinos, Large Scale Flows, Dwarf Spheroidals, Cosmological Parameters from Supernovae, the Cosmic Microwave Background, the Cosmological Constant, and Theories of Gravity.
