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 knowledge and understanding of the world which science gives us and the magnificent opportunity which it extends to us to control and use the world for the extension of our pleasure in it has never been greater than it now is.

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.

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.

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.

I count myself fortunate to be able to participate in the life of science in this era.
