The foundations of quantum mechanics has acquired tremendous importance in recent years for three reasons: First, a large number of experiments have tested concepts which previously were purely theoretical. Second, ideas from the foundations of quantum mechanics are being applied now to many fields such as condensed matter physics, quantum statistics, quantum cosmology and quantum gravity. Third, difficulties in constructing a quantum cosmology and theory of gravity have made many theorists examine the foundations of quantum theory to see if quantum mechanics itself needs to be modified. Very distinguished physicists from around the world gave talks on their recent research on a variety of theoretical and experimental aspects on these subjects at this conference.Contents: The Berry Phase as an Appropriate Correspondence Limit of the Aharonov-Anandan Phase in a Simple Model (J Christian & A Shimony)On the Nature of the Transition in Quantum Field Theory from Flat to Curved Space-Time (P J Camp & J L Safko)The Aharonov-Bohm Effect without Gauge Fields – A Paradox (I Klebanov & L Susskind)Geometrical and Topological (AN)Holonomies in Optical Experiments (R Y Chiao)Some Global Problems in Gauge Theories (F Wilczek)Experimental Verification of the Aharonov-Casher Effect for Neutrons with a Crystal Interferometer (G I Opat et al.)Fundamental Aspects of Quantum Theory Related to the Problem of Quantizing Black Holes (G ' t Hooft)A Suggested New Translation Gauge Invariance for Space-time (D Bohm)Spin and the Aharonov-Bohm Effect (C R Hagen)The Aharonov-Bohm Effect in Small Resistive Devices (R A Webb)Wave Geometry: A Plurality of Singularities (M V Berry)Analogue of the Aharonov-Bohm Effect for Black Holes and Strings (S B Giddings)Closing in on a Renormalizable and Unitary Point-Local Quantum Field Theory of Gravity (Y Ne ' eman & C-Y Lee)Gravitational Chern-Simons Term, Anyons and AB (S Deser)Experimental Confirmation of the Aharonov-Bohm Effect by Electron Holography (A Tonomura)A Geometric View of Quantum Mechanics (J Anandan)Towards a Two Vector Formulation of Quantum Mechanics (Y Aharonov & D Rohrlich)Musings on Quantum Statistics (A Zee)Topology, Quantum Theory and Dynamics (E C G Sudarshan)and other papersReadership: Experimental and theoretical physicists.Key Features:Aims to be the start of a fruitful exchange of methods and ideas on production in industrial and biological networks
