Remember that Einstein *never did* show that >"God doesn't play dice with the universe." I doubt quantum uncertainty has much effect on unpredictability of the human mind. Chaos, however, does. Each neuron is a non-linear unit, and we have 10^10 to 10^11 of them, which makes the situation so Chaotic that long term predictions (more than a half a second) would be unfeasable. But, the fact remains your hand touched the lever of your candidate. Your hand was positioned by nerves extending back to your brain. Your brain outputed nerve impulses to your hand. Those impulses cam from neurons excited by other neurons' impulses, ad almost infinitum. > Science asserts the exact opposite: That everything can be explained, that > everything can be modelled, and that the way to gain knowledge is to seek > these explanations and models. > >Whether it is indeed true that everything can be explained is another >question and once again in the philosopher's ballpark. It always seemed to me that science examined evidence, and based on that evidence cam up with ways of organizing information and making predictions. Chaos, interestingly enough, says that although you can make micro-level predictions, and it predicts that macro-level predictions of large non-linear systems is very difficult, but that all non-linear systems have certain universal characteristics. -Thomas G.
