Afterword: Memories of Richard Feynman

ByRichard P. Feynman

This chapter outlines how Richard Feynman first started on his attempt to answer the challenge of Dirac concerning the troublesome infinities that plagued relativistic quantum mechanics. James Gleick memorably summed up Feynman's philosophy towards science with the following words: "He believed in the primacy of doubt, not as a blemish upon on our ability to know but as the essence of knowing." Feynman was actively working with two of them — Finn Ravndal and Mark Kislinger, who had just been awarded his Ph.D. Feynman's 'parton model' was sweeping all before it, much to Murray's annoyance. Feynman's Nobel Prize lecture should be required reading for all aspiring scientists. In it, Feynman forgoes the customary habit of removing the scaffolding that was used to construct the new theory. Feynman was never restricted to research in any one particular field: it is to the exercise of just the freedom that people owe the Feynman Lectures on Computation.
