Every fluid—from Earth's atmosphere to blood pumping through the human body—has viscosity, a quantifiable characteristic describing how the fluid will deform when it encounters some other matter. If ...

In everyday life, all matter exists as either a gas, liquid, or solid. In quantum mechanics, however, it is possible for two distinct states to exist simultaneously. An ultracold quantum system, for ...

Physics is often about recognizing patterns, sometimes repeated across vastly different scales. For instance, moons orbit planets in the same way planets orbit stars, which in turn orbit the center of ...

(Upper) Drag is zero without quantum vortices at T = 0. (Lower) Coarse-grained quantum vortices can reproduce the prediction of the Reynolds similitude by forming a turbulent wake with high Reynolds ...
