https://en.wikipedia.org/wiki/Rudolf_Peierls https://en.wikipedia.org/wiki/Rudolf_Peierls When I was a postgrad at Birmingham University, around 1982/3 ish we had a talk by Peierls. He discussed his feelings about Heisenberg joining the Nazi party (you had to join the Party to continue to be a University lecturer in the late 1930s - that was when Einsten resolved to leave Berlin). My recollection (reaching back 30+ years here folks) is that Peierls did not blame Heisenberg- it was how it was. Peierls recollected Heisenberg talking about 'white waistcoats' and people leaving who didn't have to leave, thus reducing the number of overseas jobs available to people who did have to leave (i.e. German Jewish academics). What I'm thinking here is; How do you see the end of the wedge when it is very thin?
