Paul Dirac

The strange world of Paul DiracDirac was a peculiar man. Stories of his eccentricities abound.When Dirac first visited Niels Bohr’s institute in Copenhagen, his utterances consisted almost entirely of three phrases: “Yes”, “No” and “I don’t mind”.Later, he became more flexible. When astrophysicist Subrahmanyan Chandrasekhar expounded his views, Dirac repeatedly interjected with “Yes” but explained, “When I say ‘yes’, it does not mean that I agree; it means only that you should go on.”In 1929, Dirac sailed from America to Japan with Werner Heisenberg. During the trip, Heisenberg spent the evenings dancing while Dirac looked on, puzzled. Eventually Dirac asked his friend why he danced.Heisenberg replied: “Well, when there are nice girls it is a pleasure to dance.”After thinking for five minutes, Dirac said: “But how do you know beforehand that the girls are nice?”
