Science / Tides and Currents / Ekmanspiral : A logarithmic spiral (when projected on a horizontal plane) formed by the heads of current velocity vectors at increasing depths. The current vectors become progressively smaller with depth. They spir MORE


Entertainment / Liquor / Mak-Keol-Li: Makkeolli is a crude, raw rice wine in Korea. It is very cheap and easily found at any market. It is of an opaque cream color with low viscosity and a pungent odor. MORE


Science / Geology / Amphibolite: Amphibolite is a non-foliated metamorphic rock that forms through recrystallization under conditions of high viscosity and directed pressure. It is composed primarily of amphibole and plagioclase, usu MORE

Newtonian Fluid

Science / Chemistry / Newtonian Fluid: A fluid whose viscosity doesn't depend on gradients in flow speed. Gases and low-molecular weight liquids are usually Newtonian fluids. MORE
