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

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.

If, on occasion, the knowledge brought by science leads to an unhappy end, this is not to the discredit of science but is rather an indication of an imperfect ability to use wisely the gifts placed within our hands.

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

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.

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.

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