John von Neumann
“The sciences do not try to explain; they hardly even try to interpret; they mainly make models.”
“All stable processes we shall predict. All unstable processes we shall control.”
“Anyone who attempts to generate random numbers by deterministic means is, of course, living in a state of sin.”
“Young man, in mathematics you don’t understand things. You just get used to them.”
“If people do not believe that mathematics is simple, it is only because they do not realize how complicated life is.”
“There’s no sense in being precise when you don’t even know what you’re talking about.”
