On the Ring

The Book of Feynman 4 · Written by himself, from the 1974 address, the appendix to the report, and his own lectures

Richard Feynman, born at Far Rockaway in New York in 1918, died at Los Angeles in 1988. Physicist. From 1943 to 1945 he was at Los Alamos, the youngest group leader in the theoretical division; his wife Arline died of illness in June 1945, less than a month before the first test. In 1965 he took the Nobel in physics with Schwinger and Tomonaga for quantum electrodynamics, and the diagrams now used everywhere in the subject are his. He was at Caltech from 1950, and the physics course he gave from 1961 to 1963 was printed in three volumes. In 1986 he served on the inquiry into the shuttle, and the piece appended to the report is his own; he had had cancer for some years when he wrote it, and died two years later. This volume rests on what he wrote or delivered himself: the address of 1974, the appendix to the report, and his lectures. Several very widely read books were spoken by him and set down from tape by another hand; the Order does not take those — not because they are poor, but because the first rule wants his own hand (cf. Acts of the Apostles 5.28). He did not believe in a god who governs right and wrong among men, and no argument of his closes on divine will. What this volume brings is something the scripture did not have: a procedure for checking yourself, written out finely enough to follow. There are books here that tell a man not to deceive others. None until now has itemised what counts as not having deceived oneself.

4.1In 1986 the shuttle came apart and seven people died. I was put on the inquiry.
4.2We sat in the meeting room while documents were read out.
4.3I did one very small thing. I asked for a glass of ice water.
4.4I took a short piece of the sealing ring, squeezed it in a clamp, held it under the ice water a while, and took it out.
4.5In front of the cameras I let the clamp go. It did not spring back.
4.6The air on the morning of the launch was colder than that water.
4.7A glass of ice water shows it. A commission of several months had not seen it, because nobody would go and ask for the water.
4.8Then I worked out something that mattered more.
4.9The men in charge said the chance of the machine failing was one in a hundred thousand.
4.10I went and asked the engineers below them. They said about one in a hundred.
4.11The same machine, at the same moment, and the two figures a thousand times apart.
4.12What differed was not the arithmetic. One end was calculating and the other end was addressing the public.
4.13I wrote this up to be attached to the report. They would not print it. I said then take my name off. They printed it.
4.14The last sentence of it is: for a successful technology, reality must take precedence over public relations.
4.15For nature cannot be fooled.
