Heisenberg group by 90°. The other reflections are "xyx" and "yxy", and rotation by 180° is "xyxy" (="yxyx"). The Lie algebra formula_16 of the Heisenberg group formula_1 (over the real numbers) is the space of formula_18 matrices of the form with formula_20. The following three elements form a basis for formula_16: The basis elements satisfy the commutation relations: The name "Heisenberg group" is motivated by the preceding relations, which have the same form as the canonical commutation relations in quantum mechanics: where formula_25 is the position operator, formula_26 is the momentum operator, and formula_27 is Planck's constant. The Heisenberg group formula_1 has
The Eyes of Heisenberg Pringle rated "The Eyes of Heisenberg" two stars out of four. Pringle described the book as "a provocative novel of ideas written in this author's usual style". 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
