A revamped active exhaust system sends the V8's song exiting through cool side - exit pipes, with two
noise settings available for either a mellow rumble or something a bit louder.
In a system such as the climate, we can never include enough variables to describe the actual system on all relevant length scales (e.g. the butterfly effect — MICROSCOPIC perturbations grow exponentially in time to drive the system to completely different states over macroscopic time) so the best that we can often do is model it as a complex nonlinear
set of ordinary differential equations with stochastic
noise terms — a generalized Langevin equation or generalized Master equation, as it were — and average behaviors over what one hopes is a spanning
set of butterfly - wing perturbations to assess whether or not the resulting system trajectories fill the
available phase space uniformly or perhaps are restricted or constrained in some way.
