the Einstein theory of gravitation, which explained how all former definitions of the space-time continuum by means of rigid measuring rods, watches, light rays, and paths of inert bodies might satisfy the laws of Euclidean geometry in narrow and restricted fields, but that on the whole a more comprehensive theory of space needed to be set up.
The progress of the quantum theory exhibits the same characteristic process of transformation. The first models of atoms seemed to satisfy the demand for sensible representation in the most gratifying way. They were believed to afford a more or less direct view of the atomic world, and the microcosm appeared in exactly the same form as the macrocosm. The atom became a planetary system in which the planets were electrons revolving around a central body, the nucleus. But the simplicity of this picture was lost as the theory developed, and it was Niels Bohr himself, one of the earliest creators of the atmic model, who warned aginst overvaluing it as a representation. In his essay of 1925,"Atomtheorie und Mechanik," he expressed the conviction that the general problem of the quantum theory was not concerned with a modification of mechanical and electrodynamic theories that could be explained on the basis of ordinary physical concepts but involved a radical denial of the spacetime ideas by means of which a description of natural phenomena had previously been attempted. Atomic physics cannot be constructed "without resignation of the wish for sensuous presentation."
Quantum mechanics achieved herewith a character wholly different, in epistemological respects, from that of classical physics and mechanics. It required the development of new symbolic methods. Heisenberg relied on a new algebra, for which the symbolic character of the theory was strikingly evident in the appearance of imaginaries in the law of commutation.So the quantum theory retained indeed a mathematical schema, but this could not possibly be interpreted as
