Power is the by-product of understanding.

Knowledge is an unending adventure at the edge of uncertainty.

The values by which we are to survive are not rules for just and unjust conduct, but are those deeper illuminations in whose light justice and injustice, good and evil, means and ends are seen in fearful sharpness of outline.

The most wonderful discovery made by scientists is science itself.

After I finished my degree in India in 1980, I came to the U.S. to get a master's, and I was teaching quantum physics to freshmen. As I got my bearings as to what goes on in labs, I understood that to teach, you have to learn.

I spent most of my career doing high-energy physics, quarks, dark matter, string theory and so on.

At a time when science plays such a powerful role in the life of society, when the destiny of the whole of mankind may hinge on the results of scientific research, it is incumbent on all scientists to be fully conscious of that role, and conduct themselves accordingly.

I think British science is becoming more like American science - and then there is everybody else, I'm afraid.
