A Major Scientific Statement by the Chief Architect of Quantum Theory – essentially an unpublished “essay” on the History of Quantum Physics. Heisenberg’s papers are institutionalized, and the present may well be the only Heisenberg manuscript of its kind in private hands.
Heisenberg here explores the particle’s historical conception — contrasting Bohr’s view with current “pictures” and noting the “mathematical complication” of the modern conception. Referencing Einstein and Newton, Heisenberg then proceeds to explore the meaning of “Unified Field Theory” and equates it with “Unified Particle Theory.” Heisenberg affirms that quantum theory is essential to such a unified formulation and further states that mathematical abstraction is indispensable to its achievement. After considering the meaning and implications of a “self-contained theory,” Heisenberg concludes with “a philosophical interpretation” — propounding a “Platonic” vision of particles as “mathematical forms.”
The present manuscript bears comparison with the lectures published in Heisenberg’s book Encounters with Einstein. Though different in content and approach from these published talks, the present manuscript is probably an early and preliminary form of such lectures.
