Carl Sagan - Marcadores

I used to watch Cosmos in an old b/w TV set. But it was magic and incredibly attractive for my young self. Sagan was a long distance teacher for me. 

I still enjoy the show. And I think every body should see it. But in the first episode he says some words I would like to share with you: (something like this, sorry) 

"humans are the attempt of the universe to know itself."
