Two by Feynman: Occasional pieces add up to an autobiography

 

Feynman explaining one of his diagrams, and s couple of helpful hints for his students

Richard P. Feynman. Surely You’re Joking, Mr. Feynman? (1985) Feynman’s memoirs, recorded, assembled and edited by his student and friend Ralph Leighton.
     Feynman is one of my heroes. Ever since I heard his anecdote about how his father showed him the difference between knowing words and knowing things, I’ve been hooked on his straightforward common sense. I don’t understand his contributions to quantum mechanics, because I can’t do the math of quantum mechanics. But I understand that his approach to making sense of the world works.
     He was an intensely curious man. If he came across something he didn’t understand, he tried to figure it out. The puzzles that he loved most were about physics, but he also strove to make sense of art (he learned to draw, which trained his perception well enough that he could tell the difference between a Raphael and painting by one of Raphael’s students). He wanted to understand dreams, and how we can make images when we don’t have sensory stimuli to prompt perception (he died before fMRI scans provided the basis for an answer). He wanted to understand hallucinations, and spent several sessions in Dr Lilly’s sensory deprivation tanks.
     He liked mastering gadgets, earning pocket money as a boy by fixing broken radios. He wanted to master drumming, so he practiced, practiced, practiced. He did the same with combination locks used on file cabinets at Los Alamos when he worked at the Manhattan Project, demonstrating how insecure they were, which eventually prompted the authorities to buy better safes. (He tells how a big-wig colonel who wanted the best safe for himself didn’t bother resetting the combination from the factory setting, thus proving well before computers that the greatest weakness in any security scheme is the human being). When he discovered something that mattered to him, he changed his behaviour: when he was still a young man he stopped drinking because he didn’t want to screw up his thinking machine.
He didn’t suffer fools gladly, especially when they came on stage with pompous claims to scientific rigour. His Caltech commencement address dissected “cargo cult science”, of which he found depressingly many examples in the social sciences. He didn’t like what receiving the Nobel Prize did to his reputation: he found his fame was used by many institutions to attract audiences. To have a Nobelist as a guest speaker reflected glory on the sponsor. Feynman hated that.
     I’ve heard Feynman speak on recordings and in videos available on YouTube. Reading this book, I heard his voice again. A wonderful book by a wonderful human being. ****


Richard P. Feynman. “What Do You Care What Other People Think?” (1988) More memoirs, lectures, and anecdotes, as well as letters, sketches, and reports. Part 1 includes the title piece,  Feynman’s memoir of his first wife Arlene, who died of tuberculosis of the lymph glands. Part 2 is a dossier of his participation in the Challenger investigation. His key insight, that the rubber sealing rings in the booster joints could not adapt to cold temperatures, was prompted by his Pentagon minder, a General Kutyna, who was savvy in the ways of Washington, and so was able to give Feynman the hint that set him on the trail. The book also includes photographs, badly printed, but good enough to get an impressions of people and the occasion.
     Two things stood out for me. First, that Feynman was a private man, who took great care in showing only what he wanted to show of his inner life. His love for his wives and his family nevertheless comes through, as do his essential playfulness, and his fierce love of the truth. Then there’s his integrity. He won’t fudge the truth as he sees it, nor will he pretend certainty where there is none. A remarkable man. ****
