First of all, a disclaimer. I am making NO vouch for the validity of this paper. I just found it an amusing read and thought it's a twist from what normally happens. Typically, we tend to think that classical mechanics, even classical statistics, is completely deterministic, and that only when we get to the quantum scale would such thing be an issue for debate. But here, it seems to also apply to classical mechanics, where you get rather "predictable" dynamics even when one do not start off with a deterministic system. http://arxiv.org/abs/quant-ph/0505143 Have a go at it and see what you think...
