Stanisław Ulam citáty

Stanisław Marcin Ulam bol poľský matematik. Spolupracoval na vývoji americkej atómovej bomby. Spoločne s Edwardom Tellerom je pôvodcom Tellerovho-Ulamovho dizajnu termonukleárnych zbraní.

V matematike sa zaoberal predovšetkým teóriou čísel, teóriou množín, teóriou miery, ergodickou teóriou, dynamickými systémami a algebraickou topológiou. Po druhej svetovej vojne sa viac než rigoróznou matematikou zaoberal skôr rôznymi špekulatívnymi úvahami, napríklad ohľadne aplikácií matematiky vo fyzike, či biológii. Je po ňom pomenovaných viacero viet a matematických konceptov. Wikipedia

Stanisław Ulam: Citáty v angličtine

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

Zdroj: Adventures of a Mathematician - Third Edition (1991), Chapter 2, Student Years, p. 45 (On Ada Halpern...)
Kontext: 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 was not so much that I was doing mathematics, but rather that mathematics had taken possession of me.”

Zdroj: Adventures of a Mathematician - Third Edition (1991), Chapter 3, Travels Abroad, p. 52

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

Zdroj: Adventures of a Mathematician - Third Edition (1991), Chapter 15, Random Reflections on Mathematics and Science, p. 274

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

Zdroj: Adventures of a Mathematician - Third Edition (1991), Chapter 2, Student Years, p. 34
Kontext: 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".”

Zdroj: Adventures of a Mathematician - Third Edition (1991), Chapter 6, Transition And Crisis, p. 119
Kontext: 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.”

Zdroj: Adventures of a Mathematician - Third Edition (1991), Chapter 10, Back At Los Alamos, p. 208
Kontext: 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.”

“Mathematics may be a way of developing physically, that is anatomically, new connections in the brain.”

Zdroj: Adventures of a Mathematician - Third Edition (1991), Chapter 15, Random Reflections on Mathematics and Science, p. 277

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

On the Ergodic Behavior of Dynamical Systems (LA-2055, May 10, 1955) in [Stanisław Marcin Ulam, Analogies between Analogies, The Mathematical Reports of S.M. Ulam and His Los Alamos Collaborators, University of California Press, 1990, http://ark.cdlib.org/ark:/13030/ft9g50091s/]

“According to recent studies, at least one star out of three is multiple.”

“It is most important in creative science not to give up. If you are an optimist you will be willing to "try" more than if you are a pessimist.”

Zdroj: Adventures of a Mathematician - Third Edition (1991), Chapter 3, Travels Abroad, p. 55

“Whatever is worth saying, can be stated in fifty words or less.”

as quoted by Gian-Carlo Rota in Words spoken at the memorial service for S. M. Ulam (The Lodge, Los Alamos, New Mexico, May 17, 1984), published in The Mathematical Intelligencer, Volume 6, Number 4 / December, 1984

“Do not lose your faith. A mighty fortress is our mathematics. Mathematics will rise to the challenge, as it always has.”

In Heinz R. Pagels, The Dreams of Reason: The Computer and the Rise of the Sciences of Complexity, Ch. 3, p. 94; as quoted in Gaither's Dictionary of Scientific Quotations (Springer, 2008), p. 861

“Thoughts are steered in different ways.”

“The first sign of senility is that a man forgets his theorems, the second sign is that he forgets to zip up, the third sign is that he forgets to zip down.”

Attributed in Paul Hoffman, The Man Who Loved Only Numbers: The Story of Paul Erdős and the Search for Mathematical Truth (1998)
This has also been attributed, with variants, to Paul Erdős, who repeated the remark.

“I am always amazed how much a certain facility with a special and apparently narrow technique can accomplish.”

“I'm an agnostic. Sometimes I muse deeply on the forces that are for me invisible. When I am almost close to the idea of God, I feel immediately estranged by the horrors of this world, which he seems to tolerate…”

as quoted by Olgierd Budrewicz in The melting-pot revisited: twenty well-known Americans of Polish background http://books.google.com/books?ei=jntPUNaTMafZ0QHMloGQBQ&id=pc51AAAAMAAJ&dq=Olgierd+Budrewicz%7C&q=Sometimes+I+muse#search_anchor, publish by Interpress, page 36, 1977.

“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.”

“I thought that the description of Don Quixote's fight with the windmills the funniest thing imaginable.”

Zdroj: Adventures of a Mathematician - Third Edition (1991), Chapter 1, Childhood, p. 12

“I am turned off when I see only formulas and symbols, and little text.”
