Carl Sagan is known world-wide for being the most effective teacher ever. This series is based around his novel by the same name, which is the the best selling science book of all time. He explains how life works and how we are trying to find life elsewhere in the cosmos, how the laws of physics govern everything, how we must take care of ourselves and the earth, and so much more.
Sagan shares a sense of wonder that is both intelligent and humorous, while occasionally warning us of our capabilities of self-destruction. Though Cosmos was made during the height of the cold war, it still stands as a reminder of global problems and dangers we still need to resolve.
