Happy Birthday, Carl
Carl Sagan was born today in 1934, in Brooklyn.
I'm sure I don't have to say anything about him, but if I did, besides Cosmos and The Demon-Haunted World and The Dragons of Eden, I'd mention his insistence on putting cameras on space probes. Imagine Cassini without cameras...
He was a national treasure, no, a global - no, a specific treasure and he's missed.
