[quote=@Balance] It's something to do with chaotic systems. Those are when a small change in the initial condition makes a big change in the final result. It's not exactly random: like, for example, the double pendulum is chaotic, but everything it does makes sense and looks reasonable, you just can't calculate why. It's about that kind of predictable unpredictability. [/quote] That's a bit of an oxymoron.
