Newtons methodology is significantly richer than the hypothetico-deductive model. It is informed by a richer ideal of empirical success that requires not just accurate prediction but also accurate measurement of parameters by the predicted phenomena. It accepts theory mediated measurements and theoretical propositions as guides to research Kuhn has suggested that along with revolutionary changes in scientific theory come revolutionary changes in methodology. I will argue that, when Einstein found his theory could handle the Mercury perihelion problem, Einsteins theory was doing better than Newtons theory on Newtons standard. The richer themes of Newtons methodology continue to be strikingly realized in the testing frameworks for General Relativity.
