The Exigencies of War and the Stink of a Theoretical Problem: Understanding the Genesis of Feynman’s Quantum Electrodynamics as Mechanistic Modelling at Different Levels

1. A Question of Style In 1949, Richard Feynman (1918–1988) published the essentials of his solution to the recalcitrant problems that plagued quantum theories of electrodynamics of his days (Feynman 1949a). The main problem was that the theory, that was considered to be correct and often led to correct observable consequences, also implied that some quantities should be infinite, while by common sense or empirical evidence they were finite. Feynman devised a method of solving the relevant theoretical equations in which particular combinations of elementary solutions yielded empirically adequate results even when applied to complex problems. The
