" If the world behaved classically and predictably, the billion euros invested in LEP would have underwritten a very boring machine: every collision would just reproduce the result of the first one, and there'd be only one photograph to look at. Instead, our quantum-mechanical theories predict that many results can emerge from the same cause. And that is what we find. We can predict the relative probabilities of different results. Through many repetitions, we can check those predictions in detail. In that way, short-term unpredictability can be tamed. Short-term unpredictability is, in the end, perfectly compatible with long-term precision. "
