The current issue of Physics Today has an article by Graham Farmelo about the physicist Paul Dirac that contained an interesting quantum idea. He quotes Dirac:"The quantum jumps now form the uncalculable part of natural phenomena, to replace the initial conditions of the old mechanistic view". Farmelo then quotes another physicist Arkani-Hamed: "This is an amazing insight. Although Dirac didn't know the details of how the universe develops . .. he got the overarching concept dead right. So he was a bit like Darwin, coming up with evolution by natural selection without knowing anything about the underlying genetics".
To that I would add that 'the old mechanistic view' of weather and climate is probably adjusting to this quantum concept as we learn more from glacial ice cores about sudden changes in state of climate over the few hundreds of thousands of years. I'm thinking about those rapid warm spikes in the Northern Hemisphere near Lower Dryas time (ca. 14,000 years ago), and how our precarious civilization would (or wouldn't) adapt to such a readjustments. Even more challenging, perhaps, is the thought of how we'll adapt to climate forcing imposed by deforestation and CO2 release.
