“If people do not believe that mathematics is simple, it is only because they do not realize how complicated life is.”
― John von Neumann

“Young man, in mathematics you don't understand things. You just get used to them.”
― John von Neumann

“Everyone knows that debugging is twice as hard as writing a program in the first place. So if you're as clever as you can be when you write it, how will you ever debug it?”
― Brian Kernighan

“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, with the addition of certain verbal interpretations, describes observed phenomena. The justification of such a mathematical construct is solely and precisely that it is expected to work - that is correctly to describe phenomena from a reasonably wide area. Furthermore, it must satisfy certain esthetic criteria - that is, in relation to how much it describes, it must be rather simple.”
― John von Neumann
