A chemist who does not know mathematics is seriously handicapped.

[There] are cases where there is no dishonesty involved but where people are tricked into false results by a lack of understanding about what human beings can do to themselves in the way of being led astray by subjective effects, wishful thinking or threshold interactions. These are examples of pathological science. These are things that attracted a great deal of attention. Usually hundreds of papers have been published upon them. Sometimes they have lasted for fifteen or twenty years and then they gradually die away.

And literature frequently rises to heights that make it international.

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.

To my mind, the most important aspect of the Nobel Awards is that they bring home to the masses of the peoples of all nations, a realization of their common interests. They carry to those who have no direct contact with science the international spirit.

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

[In the case of research director, Willis R. Whitney, whose style was to give talented investigators as much freedom as possible, you may define "serendipity" as] the art of profiting from unexpected occurrences. When you do things in that way you get unexpected results. Then you do something else and you get unexpected results in another line, and you do that on a third line and then all of a sudden you see that one of these lines has something to do with the other. Then you make a discovery that you never could have made by going on a direct road.
