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

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

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.

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.

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.
