I felt like the middle of the post wandered around, but the final tirade felt suitably Feynmanish to satisfy me. It reminded me of some comments made about processes in his Challenger analysis. For instance, the bit about claiming a 3x safety margin on ring erosion while not establishing how it actually works to know whether that was a reasonable assumption.

Also, part of the assumption of these dialogs is not that Feynman is actually proposing these solutions, but that he is using them to Socratically establish to the listeners the flaws in their layout of the problem.
