# Turbulence

- kind: problem
- status: open
- year: 1883

**Statement.** Can the statistics of turbulent flow be predicted from the equations of fluid motion?

Kolmogorov's 1941 theory predicts how energy cascades from large eddies to small ones, and measurements confirm it roughly but with systematic deviations called intermittency. Engineers rely on empirical models. Feynman called turbulence the most important unsolved problem of classical physics.
