A number of scientists with greatly different backgrounds can come up with completely different assessments. The discussions or controversies are endless. Once a year we try to bring the most important discoverers together to exchange their experiences and knowledge.

The real difference between a man's scientific judgments about himself and the judgment of others about him is he has added sources of knowledge.

To my knowledge I was the first guy really to do what I do. And then later on different comedians started trying doing it.

You go to college not only for the latest knowledge but also to meet people from different backgrounds. That's the genius of the American higher-education system compared with the Europeans'. We don't simply skim the elite.

The difference between a successful person and others is not a lack of strength not a lack of knowledge but rather a lack of will.
