Bohr, Margrethe and Heisenberg are at the dinner table reminiscing about the old days, in the 20s, when Bohr and Heisenberg did some of their best scientific work together. Bohr suddenly becomes miffed because he remembers Heisenberg sent off his uncertainty principle paper to be published before Bohr had a chance to check his mathematics.
"It was not the way we worked!" Bohr chides him. Heisenberg snaps back, "The way we worked is that you drove me mad!"
Bohr retorts that the paper contained a fundamental error. This infuriates Heisenberg and then he tries to explain to his old mentor how correct his paper on the uncertainty principle actually was.
