[SciPy-User] How to estimate error in polynomial coefficients from scipy.polyfit?

I'm no expert, but the power required to overcome aerodynamic drag varies with the cube of speed -- though the physics behind that is pretty well understood.
I guess if you were doing a bulk estimate of all of the other factors (fluid density & viscosity, drag coeff, etc) this would be an applicable use case.
Like I said, I'm hardly an expert...

On this note, perhaps some of our experts might care to comment: what "physics" (in a generalized sense) gives rise to a polynomial dependency of degree higher than two? The only generic thing I can think of is something where third or higher order derivatives proportional to the independent variable are important, and those are pretty uncommon.
