While a good understanding of the onset of chaos has been achieved, using as a mathematical tool the geometric theory of differentiable dynamical systems, moderately excited chaotic systems require new tools, which are provided by the ergodic theory of dynamical systems.

Ruelle, D., 1982b, “Large volume limit of the distribution of characteristic exponents in turbulence,” Commun. Math. Unlike a normal attractor, a strange attractor predicts the formation of semi-stable patterns that lack a fixed spatial position. Phys. All this is of course very simplistic in comparison with the real weather phenomena, but it illustrates the fact that mathematicians love simple things. A phase space model of a pendulum will chart a series of points growing closer to the low point each time their trajectory takes them past it, until they cluster around the low point in a stable configuration. The notion of strange attractors and chaos goes further and suggests that no single mindset should be seen as the appropriate to all settings. Phys. Ressler, O.

This is another step towards understanding highly turbulent fluids.
