I never went into business to make money.

I really wanted to do research. That has never changed.

Invention is arrived at by intelligent stumbling.

At MIT, I had the good fortune for seven years to teach network theory, which is basic to many disciplines, to one-third of the undergraduate student body. It was an experiment to see how high we could bring their level of understanding, and it exceeded all of my expectations.

If you think something is impossible, don't disturb the person who is doing it!

The prejudice was so bad in the United States at that time that a dark person with a white person would not be served in a restaurant. My father, mother, and I would try it occasionally. We would sit there, and the food would never come.

Research in this country is going down.
