Steven Weinberg

Science merely amplifies the capabilities of human beings. Science gives us the ability to do ill and to do good more than we had, and to question science in this respect is like questioning whether people ought to have two hands or just one, because with two hands they could do more evil than they can with just one.

I was born in 1933 in New York City to Frederick and Eva Weinberg. My early inclination toward science received encouragement from my father, and by the time I was 15 or 16, my interests had focused on theoretical physics.

I would say it's a lot easier to develop a decoy system than to develop the intercontinental ballistic missile itself. I would think that any country that could develop the missile could develop quite a decoy system. It doesn't have to be terribly sophisticated.

It's very difficult to convince other countries that they shouldn't pursue nuclear weapons programs if we ourselves are actively developing a component of a strategic defense system.

My Ph.D. thesis, with Sam Treiman as adviser, was on the application of renormalization theory to the effects of strong interactions in weak interaction processes.

My work during the 1970s has been mainly concerned with the implications of the unified theory of weak and electromagnetic interactions, with the development of the related theory of strong interactions known as quantum chromodynamics, and with steps toward the unification of all interactions.
