Here in North Carolina, for many sports fans, it's considered common knowledge that basketball referees don't call fouls against Duke. The reasons for the supposed bias vary from racism, to payoffs from wealthy alums, to the intimidating atmosphere at Duke's legendary Cameron Indoor Stadium, but…
So, why math? The short version of the answer is remarkably simple: math provides a tool where you can, without ambiguity, prove that something is true or false. I'll get back to that - but first, I'm going to make a quick diversion, to help you understand my basic viewpoint on things. This…
