OK, so I'm a nerd who doesn't shut down his computers at night. Might as well donate computational time to a worthy cause.
I first heard of Carl Sagan and SETI when I watched 'Cosmos' in high school. I happened to go to Cornell as an undergrad, and have watched him speak a couple of times. I've read a few of his essays, and believe in his vision to raise the scientific consciousness of the public masses through enlightened education. His office was an unmarked office in the Astronomy building. I found that out when he actually offered a 700-level class on extraterrestrial life; it would have meshed perfectly with my undergrad project focused on the Secret of Life, however, so many people signed up for the class that he had to weed out students. Ah well.
I was saddened to hear of his passing, and now find it an honor to crunch numbers in his name. Hope we find something, out there; we can't be the only ones out there.
