Webb18 jan. 2024 · This approach, a least-action principle analogous to Fermat's principle of least time, was dubbed the “sum-over-histories” method by Wheeler. The absorber theory, which became Feynman's thesis, was eventually published in a Festschrift volume dedicated to Niels Bohr in the spring of 1945. WebbThe Principle of Least Action A.

Webbquantum theory made use of the Principle of Least Action and led to methods for the very accurate calculation of quantum electromag-netic processes, as amply confirmed by experiment. These methods rely on the famous “Feynman diagrams,” derived originally from the path integrals, which fill the pages of many articles and textbooks.
