The ebook includes of the interpretation of 2 Planck essays: 'Physikalische Gesetzlichkeit im Lichte neuerer Forschung (1926) and 'Das Weltbild der neuen Physik' (1929).
The first version of the English model used to be initially released in 1931. this is often additionally the version on which the resource experiment is based.
The booklet is a part of a five volumes [UL] 'series' of Max Planck's essays at the philosophy of physics on hand in English on P2P venues. In approximate chronological order, the 'series' includes of:

Where the masses in question have a certain magnitude, the effect of light upon the illuminated object may be disregarded. g. a single electron, is selected; because each ray of light, which strikes the electron and is reflected by it, gives it a distinct impulse; and the shorter the light-wave the more powerful is this impulse. Consequently, the shorter the light-wave the more accurately is it possible to determine position; but at the same moment measurement of velocity becomes pro portionately inaccurate; and similarly in analogous instances.
Accordingly the absolute value of the amplitude of the wave has no meaning whatever in a physical sense. If we imagine ψ to be selected in such a way that the square of the absolute value of ψ when integrated over the configura tion space, gives us the value 1, then we can also say that this square denotes the probability that the material system of particles is actually existing at the point in question within the configuration space. Thus we have found a vivid 35 expression for the physical meaning of the wavefunction ψ which we were looking for.
This observation is correct; but in itself it must not be considered a special advantage of the Quantum Theory as opposed to other theories. For the question whether a physical magnitude can in principle be observed, or whether a certain question has a meaning as applied to Physics, can never be answered a priori, but only from the standpoint of a given 4 6 theory. The distinction between the different theories consists precisely in the fact that according to one theory a certain magnitude can in principle be observed, and a certain question have a meaning as applied to Physics; while according to the other theory this is not the case.
