Any fan of determinism would need to tackle quantum physics and what seems like unavoidable randomness in it (and there are such theories, but they offer little hope of getting around the randomness from our point of view, since they hide the order from us). The typical example of a random phenomena in nature is radioactive decay. You can't predict when any given nucleus will decay, only the probability that it will happen (which gives the half-life).
