A few general characteristics of nonlinear open systems are described.
A turbulent fluid is one such system which exhibits order by supporti
ng structures in an otherwise random medium through the transfer of en
ergy from small spatial scales to large spatial scales. The spatial di
stribution of energy so derived is found to account well for two dispa
rate situations like the solar granulation and the rotation curves of
galaxies. Encouraged by these successes, one wonders if the spatial di
stribution of energy at the largest scales, i.e. V(L) proportional to
L has anything to do with the Hubble flow.
