I was impressed by this bit:
- [W]hen Feynman was mortally ill with cancer, he served on the NASA commission investigating the Challenger disaster of 1986. He undertook this job reluctantly, knowing that it would use up most of the time and strength that he had left. He undertook it because he felt an obligation to find the root causes of the disaster and to speak plainly to the public about his findings. He went to Washington and found what he had expected at the heart of the tragedy: a bureaucratic hierarchy with two groups of people, the engineers and the managers, who lived in separate worlds and did not communicate with each other. The engineers lived in the world of technical facts; the managers lived in the world of political dogmas.
He asked members of both groups to tell him their estimates of the risk of disastrous failure in each Space Shuttle mission. The engineers estimated the risk to be of the order of one disaster in a hundred missions. The managers estimated the risk to be of the order of one disaster in a hundred thousand missions. The difference, a factor of a thousand between the two estimates, was never reconciled and never openly discussed. The managers were in charge of the operations and made the decisions to fly or not to fly, based on their own estimates of the risk. But the technical facts that Feynman uncovered proved that the managers were wrong and the engineers were right.
Any thoughts on the article about Feynman?
