On Sunday night Radio 3 broadcast a long radio play (2 hours) about a meeting during the Second World War between two of the greats of quantum physics, Niels Bohr, who was Danish, and Werner Heisenberg, who was German. The meeting took place in the capital of Denmark, hence the title. It is an important incident for the ethics of science. No one really knows exactly what happened but Heisenberg seemed to want to talk to Bohr about the German atomic bomb programme. I had always thought Heisenberg was regarded as dodgy for continuing to work in Germany at this time, but a bit of Internet research suggests that his "crime" may well have been to avoid becoming a martyr and refusing to defect to America. Here's the link. Listen and see what you think.
