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).<p>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 &#x27;white waistcoats&#x27; and people leaving who didn&#x27;t have to leave, thus reducing the number of overseas jobs available to people who did have to leave (i.e. German Jewish academics).<p>What I&#x27;m thinking here is; How do you see the end of the wedge when it is very thin?
