History of science in the Renaissance trained with the "Theoricae novae" and the "Epitome". Shortly before 1514 he began to revive Aristarchus's idea that the Earth revolves around the Sun. He spent the rest of his life attempting a mathematical proof of heliocentrism. When "De revolutionibus orbium coelestium" was finally published in 1543, Copernicus was on his deathbed. A comparison of his work with the "Almagest" shows that Copernicus was in many ways a Renaissance scientist rather than a revolutionary, because he followed Ptolemy's methods and even his order of presentation. In astronomy, the Renaissance of science can be said to have ended with the works
History of the center of the Universe the Sun" from the centre of gravity of the solar system. For Newton, it was not precisely the centre of the Sun or any other body that could be considered at rest, but rather "the common centre of gravity of the Earth, the Sun and all the Planets is to be esteem'd the Centre of the World", and this centre of gravity "either is at rest or moves uniformly forward in a right line" (Newton adopted the "at rest" alternative in view of common consent that the centre, wherever it was, was at rest). Before the 1920s, it was generally
