Physics of Scale Activities

Advanced Quantum Mechanics

The Dyson lectures



One of Freeman Dyson's first tasks as a newly-minted professor of physics at Cornell in the fall of 1951 was to offer a course on quantum electrodynamics that incorporated many of the new techniques which he, Feynman, Schwinger, Tomonaga, and others had been developing. Dyson wrote up the notes to these lectures, variously titled Advanced Quantum Theory or Advanced Quantum Mechanics in mimeograph form. The mimeographs of these lecture notes are made available for viewing here.
