“Ada came from Lwów. She was a very good looking girl who was studying mathematics at the University of Geneva. For a few years I had an off-and-on romance with her.”

“It is not so much whether a theorem is useful that matters, but how elegant it is.”

“What exactly is mathematics? Many have tried but nobody has really succeeded in defining mathematics; it is always something else.”

“The mathematicians know a great deal about very little and the physicists very little about a great deal.”
