So I get the gist of Chaos Theory, and I read through another thread on this forum stating that Chaos does exist, which quotes Chaos Theory. Does this not seem to be a tad counter intuitive ? Chaos theory simply states not knowing the starting attributes of a mathematical system that you can't really predict the outcome. Thing is, Chaos doesn't seem to be a fitting adjective, it just sort of reasserts that we have no real clue LOL Correct if I'm misunderstanding but there are ALOT of things we don't know, however what we do know seems to be rather provable and reproducible mathematical systems of describing behavior under certain conditions. Of course we can write a system of equations to describe how a feather would fall in IDEAL conditions, but real conditions are never ideal. But lets say we did have the ability to measure and predict every aspect of air flow and the initial starting point of the feather etc. It could be said that in that case we could predict its landing spot from a certain height, at a certain gravity, given its mass, volume, shape and initial displacement above the ground, and any other factor that would even affect it, like the sun shining more or less, no matter how small of an effect that would have. Point is, I don't feel in an ordered universe that Chaos really exists, its just a concept that is thoroughly human relating to our lack of ultimate knowledge causing something to go other than expected. So I suppose my question is, does any branch of science really have any way of proving the existence of randomness ?
