In fracture mechanics, the theory of local symmetry predicts that, for example, a crack in a wall will grow in a direction in which the surrounding stress is symmetric around the crack's tip. Scientists at MIT have now applied this theory to the growth of river networks, finding that as a river fed by groundwater ... read more
