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.
