„In the second place, and more important, no one really knows what entropy really is, so in a debate you will always have the advantage.“
Suggesting to Claude Shannon a name for his new uncertainty function, as quoted in Scientific American Vol. 225 No. 3, (1971), p. 180.
Контексте: You should call it entropy, for two reasons. In the first place your uncertainty function has been used in statistical mechanics under that name, so it already has a name. In the second place, and more important, no one really knows what entropy really is, so in a debate you will always have the advantage.
„A large part of mathematics which becomes useful developed with absolutely no desire to be useful, and in a situation where nobody could possibly know in what area it would become useful; and there were no general indications that it ever would be so.“
"The Role of Mathematics in the Sciences and in Society" (1954) an address to Princeton alumni, published in John von Neumann : Collected Works (1963) edited by A. H. Taub <!-- Macmillan, New York -->; also quoted in Out of the Mouths of Mathematicians : A Quotation Book for Philomaths (1993) by R. Schmalz
Контексте: A large part of mathematics which becomes useful developed with absolutely no desire to be useful, and in a situation where nobody could possibly know in what area it would become useful; and there were no general indications that it ever would be so. By and large it is uniformly true in mathematics that there is a time lapse between a mathematical discovery and the moment when it is useful; and that this lapse of time can be anything from 30 to 100 years, in some cases even more; and that the whole system seems to function without any direction, without any reference to usefulness, and without any desire to do things which are useful.

Джон фон Не́йман — венгеро-американский математик и педагог еврейского происхождения, сделавший важный вклад в квантовую физику, квантовую логику, функциональный анализ, теорию множеств, информатику, экономику и другие отрасли науки.
Наиболее известен как человек, с именем которого связывают архитектуру большинства современных компьютеров , применение теории операторов к квантовой механике , а также как участник Манхэттенского проекта и как создатель теории игр и концепции клеточных автоматов. Wikipedia
„Четырьмя параметрами он может описать слона, а с пятым — заставить его махать хоботом.“
Вариант: Четырьмя параметрами он может описать слона, а с пятым — заставить его махать хоботом.

„If people do not believe that mathematics is simple, it is only because they do not realize how complicated life is.“
Remark made by von Neumann as keynote speaker at the first national meeting of the Association for Computing Machinery in 1947, as mentioned by Franz L. Alt at the end of "Archaeology of computers: Reminiscences, 1945--1947", Communications of the ACM, volume 15, issue 7, July 1972, special issue: Twenty-fifth anniversary of the Association for Computing Machinery, p. 694.
„Любой, кто принимает во внимание арифметические методы получения случайных чисел, вне всяких сомнений, заблудшая душа.“
„I think that it is a relatively good approximation to truth — which is much too complicated to allow anything but approximations — that mathematical ideas originate in empirics.“
"The Mathematician", in The Works of the Mind (1947) edited by R. B. Heywood, University of Chicago Press, Chicago
Контексте: I think that it is a relatively good approximation to truth — which is much too complicated to allow anything but approximations — that mathematical ideas originate in empirics. But, once they are conceived, the subject begins to live a peculiar life of its own and is … governed by almost entirely aesthetical motivations. In other words, at a great distance from its empirical source, or after much "abstract" inbreeding, a mathematical subject is in danger of degeneration. Whenever this stage is reached the only remedy seems to me to be the rejuvenating return to the source: the reinjection of more or less directly empirical ideas.

„Any one who considers arithmetical methods of producing random digits is, of course, in a state of sin.“
On mistaking pseudorandom number generators for being truly "random" — this quote is often erroneously interpreted to mean that von Neumann was against the use of pseudorandom numbers, when in reality he was cautioning about misunderstanding their true nature while advocating their use. From "Various techniques used in connection with random digits" by John von Neumann in Monte Carlo Method (1951) edited by A.S. Householder, G.E. Forsythe, and H.H. Germond <!-- National Bureau of Standards Applied Mathematics Series, 12 (Washington, D.C.: U.S. Government Printing Office, 1951): 36-38. -->
Контексте: Any one who considers arithmetical methods of producing random digits is, of course, in a state of sin. For, as has been pointed out several times, there is no such thing as a random number — there are only methods to produce random numbers, and a strict arithmetic procedure of course is not such a method.
„Если люди отказываются верить в простоту математики, то это только потому, что они не понимают всю сложность жизни.“

Any one who considers arithmetical methods of producing random digits is, of course, in a state of sin.
When we talk mathematics, we may be discussing a secondary language built on the primary language of the nervous system.
In mathematics you don't understand things. You just get used to them.
You wake me up early in the morning to tell me that I'm right? Please wait until I'm wrong.
If people do not believe that mathematics is simple, it is only because they do not realize how complicated life is.

Quotes about von Neumann [ edit ]
I have sometimes wondered whether a brain like von Neumann's does not indicate a species superior to that of man.
A mind of von Neumann's inexorable logic had to understand and accept much that most of us do not want to accept and do not even wish to understand.
