Abstract
It is argued that quantum mechanics must be interpreted according to the Copenhagen interpretation. Consequently the formalism must be used in a purely operational way. The relation between realism, hidden variables, and the Bell inequalities is discussed. The proof of impossibility of local hidden-variables theories (Bell's theorem) is criticized on the basis that the quantum mechanical states violating local realism are not physically realizable states.
“Einstein had great difficulty in reaching a sharp formulation of Bohr's meaning. What hope then for the rest of us.”—John S. Bell (Ref. 1, p. 189).
