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.

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.

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

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 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 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.

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