Newton’s Football (start time 5:45)  This Sunday the Denver Broncos face the Seattle Seahawks in the Super Bowl, so we thought we’d bring you a scientific perspective on the game of football. How on Earth’s Ted Burnham talks with the co-authors of the book Newton’s Football: The Science Behind America’s Game, journalist Allen St. John and science evangelist Ainissa Ramirez.
