Стани́слав Ма́ртин У́лам — польский и американский математик еврейского происхождения.
Член Национальной академии наук США .
Окончил Львовскую Политехнику, ученик Банаха. Переехал в Принстон в 1936 году и позднее участвовал в создании водородной бомбы в рамках ядерного проекта Лос-Аламосской лаборатории; внёс большой вклад в развитие математических методов, доказал множество теорем, предложил вычислительный метод Монте-Карло, выдвинул теорию ядерного ракетного двигателя. Также им сформулирована известная теорема Борсука — Улама.
Совместно с Энрико Ферми, Джоном Паста и Мэри Цингу сформулировал парадокс в теории хаоса, сейчас называемый парадокс Ферми – Паста – Улама – Цингу. В теории чисел известна т. н. скатерть Улама.
Брат Станислава — Адам Улам — профессор истории, политических наук и государственного права Гарвардского университета, автор знаменитой книги «Идеологии и иллюзии».
“For a few years I had an off-and-on romance with her.”

Контексте: 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.”

Контексте: 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.

Контексте: 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.”

Контексте: 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.
“In mathematics, as in physics, so much depends on chance, on a propitious moment.”
