Let’s face it, the universe is messy. it is nonlinear, turbulent and chaotic. It is dynamic.It spends time in transient behaviour on its way to somewhere else, not in mathmatically neat equilibria. It self-organizes and evolves. It creates diversity, not uniformity.That’s what makes the world interesting, that’s what makes it beautiful, and that’s what makes it work”. (Donella Meadows.)
