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.

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.

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.

No single achievement in science is possible without the painstaking work of the many hundreds who have built the foundation on which all new work is based.

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.

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

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