Computers are like humans - they do everything except think.

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

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

You insist that there is something a machine cannot do. If you tell me precisely what it is a machine cannot do, then I can always make a machine which will do just that.

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

I am thinking about something much more important than bombs. I am thinking about computers.

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