Truth is much too complicated to allow anything but approximations..

The total subject of mathematics is clearly too broad for any of us. I do not think that any mathematician since Gauss has covered it uniformly and f….

Computers are like humans - they do everything except think..

You don't have to be responsible for the world that you're in..

Science, as well as technology, will in the near and in the farther future increasingly turn from problems of intensity, substance, and energy, to pr….

All stable processes we shall predict. All unstable processes we shall control..

When we talk mathematics, we may be discussing a secondary language built on the primary language of the nervous system..

Technological possibilities are irresistible to man. If man can go to the moon, he will. If he can control the climate, he will..

The calculus was the first achievement of modern mathematics and it is difficult to overestimate its importance. I think it defines more unequivocall….

There's no sense in being precise when you don't even know what you're talking about..

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

I would like to make a confession which may seem immoral: I do not believe absolutely in Hilbert space any more..

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

Anyone who attempts to generate random numbers by deterministic means is, of course, living in a state of sin..

It is exceptional that one should be able to acquire the understanding of a process without having previously acquired a deep familiarity with runnin….

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

It is just as foolish to complain that people are selfish and treacherous as it is to complain that the magnetic field does not increase unless the e….

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 th….

There probably is a God. Many things are easier to explain if there is than if there isn't..

With four parameters I can fit an elephant, and with five I can make him wiggle his trunk..

The sciences do not try to explain, they hardly even try to interpret, they mainly make models. By a model is meant a mathematical construct which, w….
