Although the mathematical formalism of quantum mechanics was established by Heisenberg und Schrödinger as early as 1925/26 and soon led to dramatic progress in atomic, molecular and solid-state physics, the interpretation of the theory remains to this day by far the most controversial problem in the foundations of physics. This book deals with the more philosophical question of how the formalism of quantum theory should be interpreted. The book has two parts. Part 1 is concerned with the usual view of quantum theory. Schommers introduces the foundations, mostly from a historical point of view. Eberhard gives an introductory account of the Einstein-Podolsky-Rosen paradox and Bell's celebrated inequalities. D'Espagnat discusses realism and separability and concludes that contemporary physics does not lead to a definite conception of the world. Part 2 deals with the new aspects of quantum theory.
Eberhard shows how a modell consistent with Bell's theorem can be constructed by admitting faster-than-light action at a distance. Schommers discusses the structure of space-time and argues that physically real processes do not take place in but are projected on space-time. Selleri discusses the idea that objectively real quantum waves exist and could in principle be detected.
