Reconstruction of Quantum Mechanics
The historical development of quantum mechanics offers a rather heterogeneous picture, a large variety of interpretations, goals, and philosophical classifications. Quantum mechanics was understood as a theory in the spirit of positivism, operationalism, and empiricism, - to mention here only a few of numerous interpretations. Neither the main protagonists of quantum mechanics, Bohr, Heisenberg, Schrödinger, and Pauli agreed completely about the understanding of the new theory, nor represent individual scientists permanently the same philosophical position. As an outstanding example, we mention here Heisenberg, who changed his assessment of quantum mechanics several times.
