Current Interpretations of Quantum Mechanics

Different interpretations of quantum mechanics are presented and discussed, comparing and contrasting the various approaches to understanding the formalism of the theory.  We begin with “textbook quantum mechanics” and then discuss the Copenhagen view, operationalist quantum mechanics, hidden variable theories, Bohm-de Broglie theory, consistent histories, relational quantum mechanics, relative state approaches (many minds and many worlds), QBism, the interactional interpretation, and collapse theories.
