"A good scientist is a person in whom the childhood quality of perennial curiosity lingers on. Once he gets an answer, he has other questions."

"Life's a hazard. If you cut back on the economy intentionally, you run into enormous troubles."

"The trouble is that you won't get the scientists to agree on a course of action. It is almost instinctive in science to accept contrary views, because disagreeing gives you guidance to experimental tests of ideas — your own and those offered by others."

"Things that people learn purely out of curiosity can have a revolutionary effect on human affairs."
