We've already talked about the Monty Hall problem in 21. But what I don't really understand is why does this math whiz want to be a medical doctor? Is it just a given that this is a better direction in life than getting a Ph.D? Not that card counting has anything to do with real math.
There has been quite a bit of talk of game theory in the Batman movie (e.g. here, here and here). But the whole point was that the people did not play to their own self interests, it was more of a psychological/moral study. It did remind me of the best strategy in the game of chicken, to tear out one's steering wheel and throw it out the car (making sure the other person sees you doing it).
For anyone who lives in Chicago, Gotham City was Chicago in the movie, not really hidden at all. In fact one could consider this movie the best Chicago movie since the Blues Brothers. This caused some confusion in the plot. After all where are those ferries going to? Michigan? No I had to remind myself this was Gotham, not Chicago, and those ferries must be going to, um, New Jersey.
