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."

Every time you tear a leaf off a calendar, you present a new place for new ideas and progress.

People are very open-minded about new things - as long as they're exactly like the old ones.

Problems are the price of progress. Don't bring me anything but trouble. Good news weakens me.

We work day after day, not to finish things; but to make the future better ... because we will spend the rest of our lives there.

Great steps in human progress are made by things that don't work the way philosophy thought they should. If things always worked the way they should, you could write the history of the world from now on. But they don't, and it is those deviations from the normal that make human progress.

It is man's destiny to ponder on the riddle of existence and, as a byproduct of his wonderment, to create a new life on this earth.
