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.

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

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.

Indeed science alone may perhaps be sterile when pursued without an understanding of the world in which scientific knowledge is created and in which the fruits of science are used.

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.

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.

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