Imagine that two people have been chosen to be observers in a scien tific experiment involving two photons, or quanta of light. These pho tons originate from a single source and travel in opposite directions an equal distance halfway across the known universe to points where each will be measured or observed. Now suppose that before the pho tons are released, one observer is magically transported to a point of observation halfway across the known universe and the second ob server is magically transported to another point an equal distance in the opposite direction. .The task of the observers...

The brightest supernova explosion since the invention of the telescope has led to a corresponding explosion in research activity. This volume presents the papers from the Fourth George Mason University Workshop, held in the fall of 1987. There are numerous descriptions of the latest observations of this supernova and of the implications for theory. The book is an essential reference for all professional astronomers in stellar and galactic research who need the latest information on this fascinating phenomenon.

Bell's Theorem and its associated implications for the nature of the physical world remain topics of great interest. For this reason many meetings have been recently held on the interpretation of quantum theory and the implications of Bell's Theorem. Generally these meetings have been held primarily for quantum physicists and philosophers of science who have been or are actively working on the topic. Nevertheless, other philosophers of science, mathematicians, engineers as well as members of the general public have increasingly taken interest in Bell's Theorem and its implications. The Fall...
