\Aabstract{%
We present computational and analytical evidence that
potential (inviscid, incompressible, irrotational)
flow around a bluff body with zero drag, is
unstable and over time develops into a non-smooth turbulent solution
of the incompressible Euler equations with substantial drag.
We thus propose a resolution of dīAlembertīs paradox and
the Clay Millenium Problem on Navier-Stokes equations.
