In a science career that has spanned more than 60 years, Freeman Dyson has worked alongside some of the greatest minds in theoretical physics, including Albert Einstein, Edward Teller, Hans Bethe, and Richard Feynman.
Of course, Dyson, 90, is himself a mathematical physicist of almost legendary status. He made his name with a brilliant 1948 paper on quantum electrodynamics and went on to do pioneering work in a dizzying array of disciplines, including astronomy, spaceflight, and nuclear engineering.
In recent years Dyson has come under fire for his contrarian views on climate change. He’s been labeled a heretic–and worse. Yet he sees an important role for scientists who hold views that are unpopular or out of the mainstream.
