Problems In Quantum Physics Ii; Gdansk 89 - Recent And Future Experiments And Interpretations

The papers in this volume discuss both the theoretical concepts and experiments of the fundamental problems associated with the interpretation of Quantum Mechanics. The major theme is the continuation of the discussion between Bohr and Einstein in the light of modern technology which can turn gedanken experiments into realizable ones. Differences between various interpretations, and results of recently performed experiments (tests of Bell's inequalities, neutron interferometry, fourth order interferometry) are presented. A wide scope of possible intepretations or views are covered but no preference is given to any particular one. In addition, philosophical problems associated with the question of foundations of quantum mechanics are also discussed.
