If there is anything truly random, surely it is roulette, right? Wrong. It turns out that using chaos theory allows us to discover patterns in roulette -- such pronounced patterns that the odds increase dramatically. Nevertheless, you have to have a lot of equipment available to be able to make the more accurate predictions, so even Mandelbrot's odds wouldn't have been able to have increased under normal conditions.
Does this suggest that there is no such thing as true randomness?
