Copenhagen interpretation

Show Summary Details

Quick Reference

The anti-realist interpretation of quantum mechanics championed by the physicist Niels Bohr (1885–1962) who worked in Copenhagen, and the subject of extended debate with Einstein. According to Bohr, there is no deep quantum reality, no world of electrons and photons. There is only description of the world in these terms: quantum mechanics affords us a formalism that we can use to predict and manipulate events described in everyday languages, or the language of classical physics, but it is misguided or senseless to postulate a quantum reality answering to the description. Problems such as the wave-particle duality, or the problem of Schrödinger's cat, suggest that there is no reality behind our observations.
