Lagrangian geometry of flows Fluid flows are usually described from a fixed point in space, while Lagrangian methods that follow the fluid often rely on particle trajectories embedded in a prescribed geometry. We develop a geomet...

A new study shows how “riding along” with a fluid changes the view: the flow can seem still, #waves appear, and even fluid between two sliding plates (Couette flow) stays stable.
