In this touching video, Carl Sagan reads from his book Pale Blue Dot. Director Michael Marantz shot time-lapse video and composed beautiful music under Sagan's narration. Please have a look -- it'll put your Tuesday into perspective. It begins:
We were hunters and foragers. The frontier was everywhere. We were bounded only by the Earth, and the ocean, and the sky. The open road still softly calls.
Our little terraqueous globe is the madhouse of those hundred thousand millions of worlds.
We, who cannot even put our own planetary home in order, riven with rivalries and hatreds; are we to venture out into space?
