Ensembles take advantage of this by making multiple runs with slightly altered initial states to define the envelope of possibilities. That is the short version.
Just for some masochistic fun, I scrolled through the Wikipedia page on Navier-Stokes. That there are humans walking among us that "get" that stuff boggles my mind. How do you find anybody to talk to?? :-)
