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 ...

Scientists create toothless liquid gears that rotate on their own and could revolutionize modern industrial engines.

Rheology refers to the study of flow and deformation of materials under imposed stress. The limitations of material behavior are the ideal (Hookean) solid, which is distinguished by an elastic modulus ...
