A research problem is not solved by apparatus; it is solved in a man's head.

I expect to spend the rest of my life in the future, so I want to be reasonably sure of what kind of future it's going to be. That is my reason for planning.

Learn how to fail intelligently.

When I was research head of General Motors and wanted a problem solved, I'd place a table outside the meeting room with a sign: "Leave slide rules here." If I didn't do that, I'd find someone reaching for his slide rule. Then he'd be on his feet saying, "Boss, you can't do it."

A problem well stated is a problem half-solved.

All human development, no matter what form it takes, must be outside the rules; otherwise we would never have anything new.

The sure ways to create new ventures of discovery are to keep an open mind.
