University of Chicago physicists working in the nascent field of experimental vortex dynamics have, with unexpected help from a Sharpie marker, achieved the first measurements of an elusive but ...

This week, physicists at the Division of Fluid Dynamics meeting in Minneapolis, Minnesota, exhibited their best experimental images in a “gallery of fluid motion” Air vortices often form around the ...

This article explores viscosity, covering definitions, measurement considerations, viscometer selection, and the symbiotic relationship between viscosity and rheology. The critical elements to ...
