Introduction to Fluid Turbulence

Fluid turbulence is one of the great unsolved problems

of theoretical physics. This talk begins with a short review of some basic properties of fluids and fluid flows that highlights the intrinsic calculational difficulties. Then examplesof various flows are shown including naturally-occurring turbulent flows spanning more than 23 orders of magnitude in scale size. Finally, a brief description is given of a methodology based on the Feynman Path Integral

formulation of statistical dynamics that appears capable

of surmounting some of the technical challenges.
