Frank Merle is used to confronting a messy world. A linear equation is something like y = 2x, which states that the value of ...

Nonlinear dynamics in fluids is a research area focused on the analysis and prediction of fluid flows governed by nonlinear partial differential equations, such as the Navier–Stokes and Euler ...
