The aim of this paper is to give a brief account of the development of the mathematical equivalence of quantum mechanics. In order to deal with atomic systems, Heisenberg developed matrix mechanics in 1925. Some time later, in the winter of 1926, Schrodinger established his wave mechanics. In the spring of 1926, quantum physicists had two theoretical models that allowed them to predict the same behaviour of the quantum systems, but both of them were very different. Schrodinger thought that the empirical equivalence could be explained by means of a proof of mathematical equivalence.

This article attempts to present brief outlines of the leading interpretations of quantum mechanics. Many-worlds, relational, von Neumann–Wigner, Copenhagen and hidden variable are examined. Arguments in favor of the many-worlds interpretation are put forth, stressing the importance of further research into the fundamentals of quantum mechanics during work on quantum gravity. The history and fundamental principles of each interpretation are briefly given.
