During the last twenty years, our understanding of quantum mechanics has made much progress and the formalism itself has been generalized. This is due to the efforts of four research groups, 1-4 which have studied different aspects of the theory. The groups of Marburg1 and Geneva4 have worked on the interpretation and the formalism of quantum theory itself. Randall and Foulis,3 on the other hand, have developed generalizations of the usual statistical formalism, while Mittelstaedt and his co-workers have concentrated on the philosophical aspect of quantum mechanics. As a result, during these last years, many small modifications have been introduced into quantum theory. Put together, these small changes define a quite different theory—the new quantum theory. We want to briefly review here some of these changes.
