If people do not believe that mathematics is simple, it is only because they do not realize how complicated life is.

Science, as well as technology, will in the near and in the farther future increasingly turn from problems of intensity, substance, and energy, to problems of structure, organization, information, and control.

Young man, in mathematics you don't understand things. You just get used to them.

There is no point in being precise if you do not even know what you are talking about.

Any one who considers arithmetical methods of producing random digits is, of course, in a state of sin.

Problems are often stated in vague terms... because it is quite uncertain what the problems really are.

The most vitally characteristic fact about mathematics is, in my opinion, its quite peculiar relationship to the natural sciences, or more generally, to any science which interprets experience on a higher than purely descriptive level.
