Heisenberg picture formulation of matrix mechanics in an arbitrary basis, in which the Hamiltonian is not necessarily diagonal. It further serves to define a third, hybrid, picture, the interaction picture. In the Heisenberg picture of quantum mechanics the state vectors, |"ψ("t")"〉, do not change with time, while observables satisfy where is the Hamiltonian and <nowiki>[•,•]</nowiki> denotes the commutator of two operators (in this case and ). Taking expectation values automatically yields the Ehrenfest theorem, featured in the correspondence principle. By the Stone–von Neumann theorem, the Heisenberg picture and the Schrödinger picture are unitarily equivalent, just a basis change in Hilbert space. In
The Eyes of Heisenberg The Eyes of Heisenberg The Eyes of Heisenberg is a 1966 science fiction novel by American writer Frank Herbert. Originally serialized as Heisenberg's Eyes in "Galaxy" magazine between June and August 1966, it was issued by Berkley in the same year. The title refers to Werner Heisenberg's uncertainty principle, here applied both on the molecular (genetic) level (producing the atypical embryo the story hinges on) and on a macroscopic, societal level. The short novel takes places in an initially unspecified future in which society is rigidly stratified into two genetic and reproductive classes: the "Optimen" (who include women) and the
