Turbulence: Suddenly It's Chaos, Nature
 









Excerpts: Injecting vortices into a rotating sample of superfluid helium-3 shows
a sudden switch from smooth to chaotic behaviour, and throws light on turbulence
- one of the last unsolved problems of classical physics. (...) 
This group is studying vortices in the simplest of fluids, superfluid helium. In
a normal liquid the constituent particles are distributed over many possible
quantum-mechanical energy states. Constant collisions ensure that the behaviour
on a microscopic level is a frantic redistribution of particles among the
available states.
