I just heard on Twitter that it would have been Carl Sagan's 78th birthday today. He is a major inspiration for me and he's also the namesake of my blog. He was an astronomy professor and science popularizer. He published more than 600 scientific papers and articles. Carl Sagan was author, co-author or editor of more than 20 books.
"Somewhere, SOMETHING INCREDIBLE is waiting to be known." - Carl Sagan
Watch the tribute video below. You will probably not get those 5 minutes back, but you will be inspired and likely spend the day thinking about our place in the universe.
(If you are watching this with young children, the video has a short, but potentially disturbing series of clips featuring war.)
