A bit of an exaggeration, perhaps, but the point was that even in the theoretically deterministic world of Newtonian mechanics, only a small amount of complexity is needed to make practical prediction well nigh impossible. Thus it is perhaps not as far-fetched as it sounds to suggest that the collision 160m years ago of two space rocks, albeit quite large ones, resulted in the stormy death almost 100m years later of the dinosaurs and many other species on Earth. For although the orbits of the planets look to astronomers like a model of regular, Newtonian clockwork, on a scale of millions of years, the solar system is every [ Full article ] |
