“The way things move in a fluid is an extremely complex, dynamic thing that's characterized and defined in many different ways. But the most useful description for us is what's call the Reynolds number, which tells us whether or not the movement we're interested in is dominated by inertia or viscosity. When the Reynolds number is higher, the inertial forces dominate, which means that an object of fluid that is gliding is more likely to keep on gliding. And when the Reynolds number is lower, the viscous forces dominate, and that bring things to a halt.”
