The Measuring Process in Quantum Mechanics (On the 30th Anniversary of the Meson Theory by Dr. H. Yukawa, 1965) [1965c]
The attempt to develop a consistent theory of atomic processes has disclosed reciprocal limitations of the applicability of classical concepts, the occurrence of which can only be understood by a deeper analysis of the definition of these concepts than was necessary in classical physics. This analysis has been carried out by Niels Bohr, to whom we owe the complete elucidation of the epistemological aspect of the theory. Bohr’s approach is quite straightforward and does not appeal to any principle which is not either immediately obvious from everyday experience or well established by experiment; and his argumentation is conducted with full logical rigour. Nevertheless, it is understandable that in order to exhibit more directly the link between the physical concepts and their mathematical representation, a more formal rendering of Bohr’s argument should have been attempted, as part of an abstract formulation of the whole theory by the method of axiomatization of modern logic Such axiomatization of a physical theory would indeed be harmless if it were properly handled; but unfortunately this is still more difficult to achieve in physics than in mathematics, and in either domain, the attempt generally leads not to clarification, but to confusion.
