Neil deGrasse Tyson
What's cooler than being cool? How about being an astrophysicist who's quick with a joke, into fine wines, and once won a medal in Latin Ballroom dancing? The director of the Hayden Planetarium and host of Fox's rebooted Cosmos has proven that it's possible to explain life, the universe and everything with a sense of humor and zero condescension; his frequent appearances on The Daily Show, The Colbert Report, and Reddit have made him the face of brainiac science made accessible for the general public. Make that the "handsome face": Tyson was even named "Sexiest Astrophysicist" by People back in 2000.
