This 1968 edition, published by "Mir", presents the final major intellectual endeavor of Werner Heisenberg (1901–1976)—the founder of matrix mechanics, author of the uncertainty principle, and 1933 Nobel Prize laureate. The book summarizes Heisenberg’s work from 1957 to 1966 on his ambitious and controversial Nonlinear Spinor Theory, which sought to achieve the ultimate goal of physics: a single, unified description of all elementary particles.
In this work, Heisenberg moves away from the idea that the universe is composed of many distinct "fundamental" particles. Instead, he treats all known particles as quantized excited states of a single, self-interacting universal spinor field. The cornerstone of this theory is a fundamental nonlinear equation—often called the "world formula"—which Heisenberg believed could derive the masses and interaction constants of all particles from basic symmetries.
The monograph explores deep concepts of spontaneous symmetry breaking, the role of the vacuum state, and the mathematical challenges of non-perturbative methods in quantum field theory. Heisenberg provides a rigorous defense of his "Indefinite Metric" in Hilbert space, a daring mathematical departure from standard quantum mechanics intended to resolve the infinities that plagued the physics of the time.
This 1968 Russian translation captures a unique historical moment in theoretical physics, reflecting Heisenberg’s relentless pursuit of a "Theory of Everything." While the scientific community eventually moved toward the Standard Model, Heisenberg’s unified field theory remains a masterpiece of physical intuition and mathematical boldness. For the collector and the professional physicist, this volume is an essential record of one of the greatest minds of the century attempting to unlock the final secrets of the microcosm.
