Quote by Richard P. Feynman

“It is to be emphasized that no matter how many [amplitude] arrows we draw, add, or multiply, our objective is to calculate a single final arrow for the event . Mistakes are often made by physics students at first because they do not keep this important point in mind. They work for so long analyzing events involving a single photon that they begin to think that the arrow is somehow associated with the photon [rather than with the event].”

“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!”

“The only way to have real success in science, the field I'm familiar with, is to describe the evidence very carefully without regard to the way you feel it should be. If you have a theory , you must try to explain what's good and what's bad about it equally. In science, you learn a kind of standard integrity and honesty .”

“When I was very little, say five or six, I became aware of the fact that people wrote books. Before that, I thought that God wrote books. I thought a book was a manifestation of nature, like a tree. When my mother explained it, I kept after her: What are you saying? What do you mean? I couldn't believe it. It was astonishing. It was like--here's the man who makes all the trees. Then I wanted to be a writer, because, I suppose, it seemed the closest thing to being God.”

“I have a real aversion to machines. I write with a pen. Then I read it to someone who writes it onto the computer. What are those computer letters made of anyway? Light? Too insubstantial. Paper, you can feel it. A pen. There's a connection. A pen goes exactly at your speed, whereas that machine jumps. And then, that machine is waiting for you, just humming "uh-huh, yes?”
