A Quote by Edsger Dijkstra
John von Neumann draws attention to what seemed to him a contrast. He remarked that for simple mechanisms, it is often easier to describe how they work than what they do, while for more complicated mechanisms, it is usually the other way around.

John von Neumann gave me an interesting idea: that you don't have to be responsible for the world that you're in. So I have developed a very powerful sense of social irresponsibility as a result of von Neumann's advice. It's made me a very happy man ever since. But it was von Neumann who put the seed in that grew into my active irresponsibility!
There was a seminar for advanced students in Zürich that I was teaching and von Neumann was in the class. I came to a certain theorem, and I said it is not proved and it may be difficult. Von Neumann didn't say anything but after five minutes he raised his hand. When I called on him he went to the blackboard and proceeded to write down the proof. After that I was afraid of von Neumann.
People often criticize my films for being pessimistic; there are certainly many reasons for being pessimistic but I don’t see my films that way. They’re founded in the belief that revolution doesn’t belong on the cinema screen but outside in the world. Never mind if a film ends pessimistically but exposes certain mechanisms clearly enough to show people how they work and the ultimate effect is not pessimistic. My goal is to reveal such mechanisms in a way that makes people realize the necessity of changing their own reality.
No one has characterized market mechanisms better than Friedrich von Hayek.

To produce a really good biological theory one must try to see through the clutter produced by evolution to the basic mechanisms lying beneath them, realizing that they are likely to be overlaid by other, secondary mechanisms. What seems to physicists to be a hopelessly complicated process may have been what nature found simplest, because nature could only build on what was already there.
He [John von Neumann] had the invaluable faculty of being able to take the most difficult problem and separate it into its components, whereupon everything looked brlliantly simple.
The type of adverts to be found on television and in glossy magazines are visually designed to have a power over the mind before they can even be questioned. The dark side of my work, primarily concerns the internal mechanisms of visual imagery and how these mechanisms address the mind.
It's possible to let technology absorb what we know and then re-express it in intricate mechanisms - parts and circuit boards and software objects - mechanisms we can use but do not understand in crucial ways. This not-knowing is fine while everything works as we expected.
... The approach of von Neumann and Connes to the use of non-commutative algebra in physics is naive, the situation is much more complicated.
My greatest concern was what to call it. I thought of calling it 'information,' but the word was overly used, so I decided to call it 'uncertainty.' When I discussed it with John von Neumann, he had a better idea. Von Neumann told me, 'You should call it entropy, for two reasons. In the first place your uncertainty function has been used in statistical mechanics under that name, so it already has a name. In the second place, and more important, no one really knows what entropy really is, so in a debate you will always have the advantage.'
The ability of nonintelligent people to understand the most complicated mechanisms and to use them has always been to me a cause of astonishment: their inability to understand simple questions is even more astonishing. The general acceptance of simple ideas is difficult and rare, and yet it is only when simple, fundamental, ideas have been accepted that further progress becomes possible on a higher level.
John von Neumann was the only student I was ever afraid of.
It's the willingness on the part of people who seek personal enrichment to destroy other human beings… And because the mechanisms of governance can no longer control them, there is nothing now within the formal mechanisms of power to stop them from the creating, essentially, a corporate oligarchic state.
The only way for errors to occur in a program is by being put there by the author. No other mechanisms are known. Programs can't acquire bugs by sitting around with other buggy programs.
She couldn't think of anyone else who remotely resembled him. He was complicated, almost contradictory in so many ways, yet simple, a strangely erotic combination. On the surface he was a country boy, home from war, and he probably saw himself in those terms. Yet there was so much more to him. Perhaps it was the poetry that made him different, or perhaps it was the values his father had instilled in him, growing up. Either way, he seemed to savor life more fully than others appeared to, and that was what had first attracted her to him.
