A Quantum Mechanics without Subjective Element

Abstract

It is not easy for practicing physicists to keep track of the ongoing philosophical debate concerning the "reality'' of the entities they manipulate or the "objective validity'' of the results of their work. In addition, the role of the observer and the theory of the measuring process seem to be themselves controversial. Therefore it may be appropriate to present an interpretation of quantum mechanics which corresponds to the perspective of most practicing physicists, although the author makes no claim to possessing any particular knowledge of the literature in this domain. The final four sections present some more specific descriptions of the concepts used, so that they may also serve for more philosophical discussions.
