The increase of scientific knowledge lies not only in the occasional milestones of science, but in the efforts of the very large body of men who with love and devotion observe and study nature.

Science is the greatest creative impulse of our time. It dominates the intellectual scene and forms our lives, not only in the material things which it has given us, but also in that it guides our spirit.

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.

We live, I think, in the century of science and, perhaps, even in the century of physics.

I feel, sometimes, as the renaissance man must have felt in finding new riches at every point and in the certainty that unexplored areas of knowledge and experience await at every turn.

The increase of scientific knowledge lies not only in the occasional milestones of science, but in the efforts of the very large body of men who with love and devotion observe and study nature.

The destiny of our society is yours to make and you have a vastly greater importance to the world than we do.
