You should not fool the laymen when you're talking as a scientist... . I'm talking about a specific, extra type of integrity that is not lying, but bending over backwards to show how you're maybe wrong, [an integrity] that you ought to have when acting as a scientist. And this is our responsibility as scientists, certainly to other scientists, and I think to laymen.

Science alone of all the subjects contains within itself the lesson of the danger of belief in the infallibility of the greatest teachers of the preceding generation.

It is necessary for the very existence of science that minds exist which do not allow that nature must satisfy some preconceived conditions.

If you think you understand quantum mechanics, you don't understand quantum mechanics.

Of course, you only live one life, and you make all your mistakes, and learn what not to do, and that's the end of you.

The exception tests the rule.
