According to this view, everything that takes place in the world could be explained, at least in principle, by the ultimate version of physics. But in truth, physics only reigns over small, easily modelled, subsections of reality. If we look at how science actually works when dealing with real-life, complex problems, we’ll see that physics plays only a small part, alongside a motley assembly of other natural and social sciences, engineering, and other disciplines, working together. The world is beautifully dappled, and requires a dappled science to explain it, argues Nancy Cartwright.  Physics, they say, is queen of the sciences.
