Citações Stanislaw Ulam

„For a few years I had an off-and-on romance with her.“

—  Stanislaw Ulam

Fonte: Adventures of a Mathematician - Third Edition (1991), Chapter 2, Student Years, p. 45 (On Ada Halpern...)
Contexto: 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.

„I never really experienced a breakdown, but have felt "strange inside" two or three times during my life.“

—  Stanislaw Ulam

Fonte: Adventures of a Mathematician - Third Edition (1991), Chapter 2, Student Years, p. 34
Contexto: Thinking very hard about the same problem for several hours can produce a severe fatigue, close to a breakdown. I never really experienced a breakdown, but have felt "strange inside" two or three times during my life.

„It is like hidden parameters in physics, this ability that does not surface and that I like to call "habitual luck".“

—  Stanislaw Ulam

Fonte: Adventures of a Mathematician - Third Edition (1991), Chapter 6, Transition And Crisis, p. 119
Contexto: There may be such a thing as habitual luck. People who are said to be lucky at cards probably have certain hidden talents for those games in which skill plays a role. It is like hidden parameters in physics, this ability that does not surface and that I like to call "habitual luck".

„Given this optimistic nature, I feel this way even now when I am past sixty.“

—  Stanislaw Ulam

Fonte: Adventures of a Mathematician - Third Edition (1991), Chapter 10, Back At Los Alamos, p. 208
Contexto: I was still very hopeful that much work lay ahead of me. Perhaps because much of what I had worked on or thought about had not yet been put into writing, I felt I still had things in reserve. Given this optimistic nature, I feel this way even now when I am past sixty.

„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.“

—  Stanislaw Ulam

„As one sharpens a knife on a whetstone, the brain can be sharpened on dull objects of thought. Every form of assiduous thinking has its value.“

—  Stanislaw Ulam
