Abstract

We have to distinguish between the scientific revolution which was bound on the work of Copernicus and the cultural-ideological changes that have accompanied and framed this revolution. The "Copernican" revolution was in the beginning a constituent of cultural and ideological changes at the end of Renaissance but it became a scientific revolution only with Galilei and Kepler. This was the first scientific revolution which inagurated the internal dynamics of the scientific development. A necessary condition of that revolution was the incorporation of a consistent physical dynamics into astronomy. This happened with the formulation of Kepler's laws and the Galilei's postulates of relative movements, the law of inertia and of free fall, which are valid for all physical cosmos.
