52: Fluid Dynamics
( \newcommand{\kernel}{\mathrm{null}\,}\)
Fluid dynamics, studies fluids in motion. It is a complex subject; in fact it's probably the most complex of the physical sciences. Even fairly simple physical systems can have very complicated solutions, and some subjects, such as fluid turbulence, are a long way from being well understood. The study of fluid flow is of great importance in fields like chemical engineering and meteorology.
