Only a small part of scientific progress has resulted from planned search for specific objectives. A much more important part has been made possible by the freedom of the individual to follow his own curiosity.

Many of the things that have happened in the laboratory have happened in ways it would have been impossible to foresee, but not impossible to plan for in a sense. I do not think Dr. Whitney deliberately plans his serendipity but he is built that way; he has the art-an instinctive way of preparing himself by his curiosity and by his interest in people and in all kinds of things and in nature, so that the things he learns react on one another and thereby accomplish things that would be impossible to foresee and plan.

The scientist is motivated primarily by curiosity and a desire for truth.

A chemist who does not know mathematics is seriously handicapped.

Happy indeed is the scientist who not only has the pleasures which I have enumerated, but who also wins the recognition of fellow scientists and of the mankind which ultimately benefits from his endeavors.

History proves abundantly that pure science, undertaken without regard to applications to human needs, is usually ultimately of direct benefit to mankind.

Medicine also disregards national boundaries.
