I just wanted to add two interesting facts:
1-Galileo was also very near to demonstrate the Earth’s movement thanks to the pendulum. Unfortunately he died before it (not executed as some people believe, but from old age). I find it amazing to see the direction of his investigation in the last period of his life, as he could never demonstrate heliocentrism and it was necessary to wait until 1851(two centuries!) when Foucault could finally present the final proof of the Earth’s movement, which, even being the most plausible theory was just indeed an unproven theory until then.
2-Precisely, Galileo changed the physics studies completely, but as some people consider it a revolution, I think it is precisely the contrary: the extension, or even more, the reaffirmation of the path that the Greeks started, thus not a revolution, but the application of the known way better than anyone. And of course, following previous scientists, without loosing any merit from this. The problem is the lack of history knowledge might present the period after the Greeks as completely sterile, and later the Middle Ages, precisely when the new germ that transformed, thanks to Galileo, into modern science was formed. What I mean is that behind him there was a chain of people who more or less contributed (true that with not so much enthusiasm as Galileo) to the discoveries that he later made. His starting point then was the work of the usually forgotten Domingo de Soto about gravity and inertia, probably the most relevant of Galileo’s predecessors.
