Feynman is well-known for his TV appearance where he dramatically demonstrated what happened with the O-rings, live...but in his memoir, &quot;What Do You Care What Other People Think?&quot;, he credits being inspired by General Kutyna, who had asked him to join the commission. Feynman describes that a random comment from Kutyna led him down the path of revelation:<p>&gt; <i>Then he says, “I was working on my carburetor this morning, and I was thinking: the shuttle took off when the temperature was 28 or 29 degrees. The coldest temperature previous to that was 53 degrees. You’re a professor; what, sir, is the effect of cold on the O-rings?” “Oh!” I said. “It makes them stiff. Yes, of course!” That’s all he had to tell me. It was a clue for which I got a lot of credit later, but it was his observation. A professor of theoretical physics always has to be told what to look for. He just uses his knowledge to explain the observations of the experimenters!</i><p><i>However</i>, Feynman admits at the end of his multi-chapter account of serving on the commission that Kutyna had coyly <i>played</i> Feynman:<p>&gt; <i>Another thing I understand better now has to do with where the idea came from that cold affects the O-rings. It was General Kutyna who called me up and said, “I was working on my carburetor, and I was thinking: what is the effect of cold on the O-rings?” Well, it turns out that one of NASA’s own astronauts told him there was information, somewhere in the works of NASA, that the O-rings had no resilience whatever at low temperatures—and NASA wasn’t saying anything about it. But General Kutyna had the career of that astronaut to worry about, so the real question the General was thinking about while he was working on his carburetor was, “How can I get this information out without jeopardizing my astronaut friend?” His solution was to get the professor excited about it, and his plan worked perfectly.</i><p>If we take Feynman at his word, to me this is a great description of how science and bureaucracy and invention (and, sometimes, disaster) works: it&#x27;s not always just random eurekas, or study-real-hard-and-you&#x27;ll-figure-it-out...sometimes the information is already well-known, and obvious, but for various logistical&#x2F;political&#x2F;bureaucratic reasons, it isn&#x27;t immediately disseminated or explored.<p>via: Feynman, Richard P.
