Mathematical Supplement,nctions ψ(., .) are not orthogonal, but the eigendifferentials Δψ(., .) are. Furthermore, because the Δψ(., .) have finite spatial extension, they can be normalized. Then in the limit Δ.→ 0, a meaningful normalization of the functions ψ(., .) themselves follows: the normalization on δ-functions.

,The Schr?dinger Equation,ch an equation, not derived but guessed at intuitively, would then be a postulate of the new theory, and its validity would have to be checked by experiment. This equation for the calculation of quantum-mechanical states is called the . .; let us now “derive” it.

Identical Particles,s we will not be able to establish later on whether particle no. 1 or no. 2 or another particle can be found at the point in space .. Because of the possible interaction (momentum exchange etc.), dynamical properties cannot be used to distinguish between them, either.

Conceptual and Philosophical Problems of Quantum Mechanics,ion made by quantum mechanics has been disproved experimentally. In spite of this success, conceptual problems of the theory exist; in fact, there have been many attempts to interpret quantum mechanics in a new way or even to replace it by another theory based on a more obvious conceptual and philosophical foundation.

A number of misprints and minor errors have been corrected and a few clarifying remarks have been added at various places. A few figures have been added or
