With Cosmos, Carl Sagan and his wife and co-writer, Ann Druyan, brilliantly illustrated the underlying science of his same-titled book, placing the human species within a space-and-time context that brought the infinite into stunningly clear view. The series, which originally aired in 1980 on PBS, has been seen by more than 700 million people worldwide and remains a high-water mark in miniseries history.Sagan lucidly explains such topics as Einstein's theory of relativity, Darwin's theory of evolution, and the greenhouse effect, bringing the mysteries of the universe down to a layman's level of understanding. The footage in these remastered, seven-DVD or seven-VHS sets is as fresh and riveting as it was two decades ago and is certain to fire the imaginations of a whole new generation of viewers. This is THE GREATEST television series ever.Its original airing in 1979 inspired me to a love of science, learning, and freedom of inquiry that have shaped both my interests and intellectual curiosity. Of the hundreds of high-quality science doc series released in the interim, none approach the majesty and depth of this one. An elegant and artisitc enterprise for a well-organized, self-correcting way of reasoning and thinking about the universe/time we occupy. After a quarter of a century, this series is as captivating as it is an education.
