"Science shows us truth and beauty and fills each day with a fresh wonder of the exquisite order which governs our world."

"To those of you who study history, economics, sociology, literature and language I present the challenge of the utilization of the enormous resources in our grasp to the problem of creating a genuinely good life for yourselves and your children."
