On the way to Chicago's O'Hare airport for my flight to Afghanistan I visited the "South Side" to take in some of it's attractions... starting at the lakefront with The Museum of Science and Industry (aerial view). One of the exhibits on mathematical probability, something they called Pascal's Triangle", looked like it was made of billiard balls. I couldn't figure it out, so I asked them to rack it up again. How are you supposed to bet on this f*ing thing?
