Heisenberg reflects on the beginning of modern atomic physics he invented quantum mechanics while working with Niels in the 1920s. In this opening segment, Margrethe and Niels Bohr consider why Werner Heisenberg came to Copenhagen during the war the world remembers only two things about Heisenberg. In Frayn's play, Heisenberg meets Bohr and his wife Margrethe once again to look for the answers and to work out how we can ever know why we do what we do. The meeting was fraught with danger and embarrassment and ended in disaster. But now the world had changed and the two men were on opposite sides in a world war. Old friends and close colleagues, they had revolutionized atomic physics in the 1920s with their work together. This adaptation of the award-winning Michael Frayn play 'Copenhagen' is based on the true story of a trip the German physicist Werner Heisenberg made to Copenhagen in 1941 to see his Danish counterpart Niels Bohr.
