Carl Sagan teaching school kids.

You'll want to watch that video with Carl Sagan, (1934-1996). It's just GREAT! Interesting, fascinating,puzzling, amazing, enlightening! Many thanks to you Carl Sagan.You were among the best and brightest in the sweetest of ways. One quote:"We make our world significant by the courage of our questions and by the depths of our answers. Another one from his official website: "We are a way for the Cosmos to know itself." http://www.carlsagan.com/ You can also listen to him talking to Martians in case we made it there: http://www.carlsagan.com/media/GreetingSagan64k.mp3
