The complementarity principle is one of the most important methodological and heuristic principles of science, as well as one of the most important principles of quantum mechanics, formulated in 1927 by Niels Bohr. According to this principle, for a complete description of quantum-mechanical phenomena, it is necessary to use two mutually exclusive (“additional”) sets of classical concepts, the totality of which provides comprehensive information about these phenomena as integral ones.
