Rare Manuscript Leaf Of Calculations, Written Entirely In Nobel Prize-Winning Physicist Richard Feynman’s Hand 18. FEYNMAN, Richard P. Manuscript leaf. No place, no date. Single unlined sheet of onionskin paper, measuring 8-1/2 by 10-3/4 inches; p. 1; floated and framed with a portrait, entire piece measures 22-1/2 by 18-1/2 inches. $12,500. Fascinating and rare manuscript leaf of mathematical calculations, very likely lecture notes for a graduate course that Feynman taught on the mathematical methods of physics at Caltech during the early 1970s, written on the recto entirely in Richard Feynman’s hand. In one of Feynman’s famous lectures, he remarked: “To summarize, I would use the words of Jeans, who said that ‘the Great Architect seems to be amathematician.’ To those who do not know mathematics it is difficult to get across a real feeling as to the beauty, the deepest beauty, of nature. C.P. Snow talked about two cultures. I really think that those two cultures separate people who have and people who have not had this experience of understanding mathematics well enough to appreciate nature once.” About-fine condition, with only mildest edge toning and rough top edge from notebook removal.
