In this visionary look into the future, Freeman Dyson argues that technological changes fundamentally alter our ethical and social arrangements and that three rapidly advancing new technologies - solar energy, genetic engineering, and worldwide communication - together have the potential to create a more equal distribution of the world's wealth.

Dyson begins by rejecting the idea that scientific revolutions are primarily concept driven. He shows rather that new tools are more often the sparks that ignite scientific discovery. Such tool-driven revolutions have profound social consequences: the invention of the telescope turning the medieval view of the world upside down, the widespread use of household appliances in the 1950s replacing servants, to cite just two examples. In looking ahead, Dyson suggests that solar energy, genetics, and the Internet will have similarly transformative effects, with the potential to produce a more just and equitable society.

Written with passionate conviction about the ethical uses of science, The Sun, The Genome, and The Internet is both a brilliant reinterpretation of the scientific process and a challenge to use new technologies to close, rather than widen, the gap between rich and poor.
