The Not So Random Coin Toss
NPR has a great audio segment on the randomness of the coin toss. They also interview statistician Persi Diaconis who asked Harvard University engineers to build him a mechanical coin flipper (seen below) that can always make the perfect coin flip. It appears that the randomness in a coin toss is introduced by sloppy humans.
They also bring up the issue of American Football games that are started with a coin flip. Listen to the segment in Real or Windows Media formats.
