Quantum Mechanics: Philosophy & Interpretations

Abstract

We discuss and review the philosophy and interpretations of quantum mechanics.Technically, QM is a set of mathematically formulated prescriptions that serve for calculations of probabilities of different measurement outcomes. The most serious problem has been the inability to demarcate with mathematical precision just where microscopic processes leave off and where macroscopic processes begin. The fact that observers report definite outcomes of experiments has, therefore, been a mystery. Explanations of this mystery have supplemented QM with a wide variety of additional assumptions.
