Über den anschaulichen Inhalt der quantentheoretischen Kinematik und Mechanik

Heisenberg’s 1927 Über den anschaulichen Inhalt der quantentheoretischen Kinematik und Mechanik, published in Zeitschrift für Physik, is one of the program’s working technical references. Cited in Book IV (Categorical Microcosm), Part 2, Chapter The Address-Obstruction Theorem, where the program draws on it in the context of “Historical Context Heisenberg’s 1927 paper introduced uncertainty through a gedankenexperiment: measuring an electron’s position with a γ-ray microscope disturbs its momentum.”
