In condensed matter physics, there is an area called turbulence that has wide practical application: weather, golfing, navigation, bridges, , boats, and planes.
(Most of you know turbulence from .)
But for theoreticians, turbulence is different.
In 1941, some Russian guy wrote a theory for the dissipation of vortices in highly turbulent flows:
Since then…nothing. Any significant contribution to turbulence has been beyond smartest minds in theoretical physics, despite discovered by 19th century classical physics.
In physics, we like to say:
Turbulence is the graveyard of great physicists.
