Live with purpose. Don't let people or things around you get you down.

Necessity is the mother of all invention.

My sense of god is my sense of wonder about the universe.

Mankind must give up war in the Atomic Era. What is at stake is the life or death of humanity.

The only real valuable thing is intuition.
