Some people are just cool. Like Neil DeGrasse Tyson! Not only is he the director of the Hayden Planetarium at the Natural History Museum in NYC, but he is also the author of books like: Death By Black Hole and The Sky is Not the Limit: Adventures of an Urban Astrophysicist.
He's been interested in astronomy since he was a kid, and was actually attempted solicited by Carl Sagan to attend Cornell instead of his later decided Harvard. Also, he was selected as the sexiest astrophysicist by People Magazine in 2000. Nice. He's got charisma.
He makes for a great evening of watching on YouTube. And, he said this:
"Of course I let my toddler play with spilled milk. It's obvious she is studying fluid dynamics."
