Query: Protective measurements of the wave function of a single system   My view on the meaning of the quantum wave function and its connection to
protective measurements is described. The wave function and only the wave
function is the ontology of the quantum theory. Protective measurements support
this view although they do not provide a decisive proof. A brief review of the
discovery and the criticism of protective measurements is presented. Protective
measurements with postselection are discussed.
