Yet we still hold on to our belief that the law of equilibrium is absolute. We cling to it because the entire Newtonian system, of which equilibrium is one part, has been our model for how to think about the world for three hundred years. Letting go of such deeply embedded ideas is not easy. However, in the spirit of Newton, Galileo, and Copernicus, we must be willing to see the world as it is, and that means making room for new ideas.
