In that period, Niels Bohr was on a lecture engagement at the Princeton University and I remember one afternoon Willis Lamb came back very excited and said that Bohr had leaked out great news.
Damals hielt Niels Bohr Vorlesungen an der Princeton University, und eines Abends kam Willis Lamb begeistert zurück und erzählte, dass Bohr große Neuigkeiten verkündet hatte.
