If a guy tells me the probability of failure is 1 in 100,000, I know he's full of crap.

In fact the total amount that a physicist knows is very little. He has only to remember the rules to get him from one place to another and he is all right.

Science is a way to teach how something gets to be known, what is not known, to what extent things are known (for nothing is known absolutely), how to handle doubt and uncertainty, what the rules of evidence are, how to think about things so that judgments can be made, how to distinguish truth from fraud, and from show.

While I am describing to you how Nature works, you won't understand why Nature works that way. But you see, nobody understands that.

This is not very important what I'm doing. I'm just proving something.

I couldn't claim that I was smarter than sixty-five other guys--but the average of sixty-five other guys, certainly!

I don't think that the laws can be considered to be like God because they have been figured out.
