Fun and interesting story around a friend and colleague of mine about the World Cup ball. He has been on TV a lot lately...CNN, BBC, Bloomberg, and many others. BTW, he has published extensively on the aerodynamics of all kinds of balls including baseballs. He's even talked to our younger son about things he can do with a baseball.
Fun stuff!
