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

A chemist who does not know mathematics is seriously handicapped.

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

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.

Science, almost from its beginnings, has been truly international in character. National prejudices disappear completely in the scientist's search for truth.

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.
