Overview: Interview with Freeman Dyson, British/American theoretical physicist (in the living room of his home in Princeton, New Jersey). Dyson talks about gamma-ray bursts, the secrets of the universe, solar eclipses (an example of pure beauty, according to Dyson), Stephen Hawking (also a theoretical physicist), the lack of a scientific understanding of beauty, the complexity of the brain, and the question of whether animals have a sense of beauty.
