Neil deGrasse Tyson Tweets of the Day

Astrophysicist Neil deGrasse Tyson is best known for his musings on the space program, going to Mars, and James Cameron's issues with starmaps. But during last night's Major League Baseball All-Star Game, he shifted gears and instead commented on the big questions -- you know, things like "Why is it called the foul pole when it's fair territory?" and "How much force does it take to throw a 100 mph fastball?" Like most of deGrasse Tyson's everything, it was both informative and awesome. [thanks, nick!]
