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.

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

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

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.

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.

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.
