Old Quantum Mechanics

Various perturbations of the Kepler and harmonic elliptic motions are considered in the frame of the old quantum mechanics. It is shown that the degeneracy of the unperturbed levels is entirely removed by these perturbations.

Quantum mechanics is more creativity than relativity theory. How does quantum mechanics impact the paradigm of classical physics? Although both Einstein and Bohr raised relatively vague questions about the old paradigm of physics, such as Einstein's question about differential equations and Bohr's use of "blind crutches" to question the cognitive function of experimental instruments. But there has been no outright skepticism.
