IMPORTANT NOTE: For those of you following my class, this video is horribly out of sequence. We basically jumped ahead 20 or so lectures. Thus, if you've never seen any Bayesian games before, you are going to be horribly lost, especially because I don't do much explaining in the video. However, I needed to upload it for another side project I'm working on. So if you've seen Bayesian games before, consider it more practice. If you haven't, think of it as a horrendously complicated preview of ...

William Spaniel explores the proof for geometric series, which are necessary for games that model time in the interaction. However, this video is suitable to students of calculus exclusively. The Burning Question: In the movie IQ, Meg Ryan is standing 2 feet away from Tim Robbins. She tells him that he can walk half the distance to her. Then, he can walk half the remaining distance. Then he can walk half the remaining distance again. And so forth. If he ever reaches her, he may kiss her ...

The Transportation Security Administration (TSA) recently announced new flight restrictions--to prevent attacks similar to the incident in Detroit, no one can get out of their seats or have anything on their laps for the last hour of a flight. Unfortunately, this is a ridiculous restriction that won't stop any terrorists and only annoy passengers needlessly. In this video, I explain why terrorists will still be successful despite the new restrictions using a simple game theoretical model and ...
