This chapter describes the realistic interpretation of realism and quantum mechanics. Quantum mechanics is considered a theory of the microworld. The philosophical notions about quantum mechanics held by many philosophers and theoretical physicists are incompatible with the actual practice of the working scientist. The lack of a well-founded philosophical discourse on quantum mechanics has harmful consequences in research and in teaching. Nevertheless, quantum theory is by no means in a state of crisis. In quantum system, the measuring apparatus is described positively in terms of classical or engineering physics. In quantum physics, man's consciousness does not enter the physical discourse in any other way than in classical physics. Contemporary quantum mechanics requires an engineering approach with a division into a part “that sees” and a part “that is seen.” According to the formalism of quantum mechanics, this cut is context dependent and not identical with the Cartesian cut. The Cartesian separation would require an intrinsic separation of the whole reality into res extensa and res cogitans, while engineering quantum mechanics requires a contextual subject-object tensor-product decomposition of the whole reality such that there are no Einstein-Podolsky-Rosen correlations between the observed object and the observing tools.
