“It helps to imagine under what conditions a man would be swimming at, say, the same Reynolds number as his own sperm. Well you put him in a swimming pool that is full of molasses, and the you forbid him to move any pare of his body faster than 1 cm/min. Now imagine yourself in that condition; you’re under […]

Sheep are a fluid (as will be explained tonight in Washington)
Nicole Sharp explains, in FYFD, how sheep are, more or less, a fluid: Not all fluids are, well, fluid. Traffic, flocks of birds, ants, and even sheep can behave like fluids. This video shows an aerial perspective on sheep being herded, and despite the four-legged nature of these particles, they have a lot of fluid-like characteristics.… […]
The Rheology of Ant Swarms
Room 007 of the Love Building at Gatech, Atlanta, Georgia is the home of the Hoogle Lab. It’s run by David L. Hu (Assistant Professor of Fluid Mechanics) who is the corresponding author for the robotic jumping-beans study which Improbable recently profiled. But the Hoogle Lab doesn’t exclusively focus on jumping beans, it also investigates the […]
Birth-Fluid Dynamics, and the Splashy Hydrodynamics of Urination
Aatish Bhatia (of Empirical Zeal) alerts us to an outpouring of soon-to-be-announced birth-centric and micturation-modulation fluid dynamics insights. Anne Staples [pictured here], of Virginia Polytechnic Institute and State University, will chair a session on “Pumping Phenomenon“, at the American Physical Society’s 66th Annual Meeting of the APS Division of Fluid Dynamics,in Pittsburgh, Pennsylvania, on Sunday, […]
