[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.

Train yourselves. Don't wait to be fed knowledge out of a book. Get out and seek it. Make explorations. Do your own research work. Train your hands and your mind. Become curious. Invent your own problems and solve them. You can see things going on all about you. Inquire into them. Seek out answers to your own questions. There are many phenomena going on in nature the explanation of which cannot be found in books. Find out why these phenomena take place. Information a boy gets by himself is enormously more valuable than that which is taught to him in school.

A chemist who does not know mathematics is seriously handicapped.

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

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

And literature frequently rises to heights that make it international.

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.
