This series of cassettes on Science & Discovery recreates one of history's most successful journeys -- 4,000 years of scientific efforts to better understand the physical world. Science has often challenged and upset conventional wisdom of accepted practices; these are the stories of vested interests and independent thinkers, experiments and theories, change and progress. Aristotle, Copernicus, Kepler, Galileo, Newton, Darwin, Einstein, and many others are featured. Narrator Edwin Newman is a celebrated journalist, author, and lecturer. He was for 35 years a television jouranlist for NBC News, and he's familiar to millions as a moderator of presidential debates.
