(Phys.org)—An airplane's vortex generators, which look like small fins on its surface, improve the plane's aerodynamics similar to the way in which the dimples on a golf ball improve the ball's aerodynamics: by delaying ...
(Phys.org)—When you open your door on a cold winter day, the warm air from your home and the cold air from outside begin to mix and evolve toward thermal equilibrium, a state of complete entropy where the temperatures outside ...
It's widely known that thick, viscous liquids—like honey—flow more slowly than low-viscosity liquids, like water. Researchers were surprised to find this behavior flipped on its head when the liquids flow through chemically ...
