Using centuries old equations of fluid motion, supercomputers can be used to simulate turbulent flow in fine detail. But theoretical physicists are still unsure as to how these equations actually work ...

Astronomical measurements of motion frequently utilize the Doppler effect, observing shifts in wavelength (or frequency) of emitted waves from moving sources, analogous to a changing siren pitch.
