Legendary physicist Freeman Dyson talks about math, nuclear rockets, and astounding things about the

Mathematician and physicist Freeman Dyson has had a career as varied as it has been successful. A former professor of physics at Princeton's Institute for Advanced Study, he has worked on the unification of the three versions of quantum electrodynamics invented by Richard Feynman, nuclear reactors, solid-state physics, ferromagnetism, astrophysics, biology, and the application of useful and elegant math problems. One of his ideas, the Dyson Sphere, was featured in a "Star Trek" episode....
