EYNMAN SOLVED THAT PROBLEM
: Feynman and Welton 1947, a book-length report, draws together the chief findings of Feynman and his group on critical-mass calculations and neutron scattering. Feynman’s own contribution to the version of the problem in which neutrons are assumed to have a single characteristic velocity—a practical simplification of methods developed by others— appears in Feynman 1946b.

HAT SEEMED AN IMPOSSIBLE LEAP
: Ashkin, Ehrlich, and Feynman 1944. Welton recalled wryly (1983, 14): “Only a short period of reflection was … required before Feynman announced that we were going to take the accumulated computational results from T-2. put them through the meat grinder, season them with some further insights (yet to be produced) and extrude this mixture as a handy interpolation-extrapolation formula.”

EYNMAN THOUGHT AT FIRST
: F-H, 55–56: “We discovered a very annoying thing that we didn’t understand…. When we set up the differential equation, we solved it numerically and the numbers seemed to come out irregularly. Then we would check and it would be the same thing…. The points would sort of wiggle around irregularly, and [von Neumann] explained that that was correct, that was all right, that was very interesting…. And there was nothing we could do about it. We just had to live with it, and we did…. We were terribly surprised by the fact that we would do the numbers over again, and it was the same crazy irregularities.”
