That's not a unique property of the Golden ratio though. The statement holds for every zero of a real polynomial, i.e. every complex number. So yes, it's neat, but not because of the Golden ratio involved!
i'm not sure i agree with that.. a second order homogenous differential equation has a unique characteristic polynomial, and there is only one polynomial equation for φ
I guess one can argue that the ODE looks nice, which comes from the polynomial having integer coefficients. But: Many other algebraic numbers have cool ODEs associated with them, not just phi.
yea! i actually got curious and exploring that now.. except i'm looking at recursively defined functions
