Why donít we understand turbulence?

Help Desk A reader wrote in about an interesting Wired article: Why donít we understand turbulence?.
The trouble is complexity. When a stream of water or air goes turbulent, groups of molecules form vortices of widely varying sizes that interact in seemingly random ways. To determine the outcome, weíd have to measure the initial conditions to an impractical degree of precision. And in any case, tracking a zillion particles is beyond the reach of any conceivable computer.

Wonder if anyone might have something to add or comment? A wiki area is available to capture the debate.
