Monetae cudendae ratio is a paper on coinage by which Renaissance- and Reformation-era mathematician and astronomer who formulated a model of the universe that placed the Sun rather than the Earth at the center of the universe?
Nicolaus Copernicus Nicolaus Copernicus ( ; Polish: "Mikołaj Kopernik" ; German: "Nikolaus Kopernikus; Niklas Koppernigk" ; 19 February 1473 – 24 May 1543) was a Renaissance- and Reformation-era mathematician and astronomer who formulated a model of the universe that placed the Sun rather than the Earth at the center of the universe, likely independently of Aristarchus of Samos, who had formulated such a model some eighteen centuries earlier.
Vera Rubin Vera Cooper Rubin (July 23, 1928 – December 25, 2016) was an American astronomer who pioneered work on galaxy rotation rates. She uncovered the discrepancy between the predicted angular motion of galaxies and the observed motion, by studying galactic rotation curves. This phenomenon became known as the galaxy rotation problem, and was evidence of the existence of dark matter. Although initially met with skepticism, Rubin's results were confirmed over subsequent decades. Her legacy was described by "The New York Times" as "ushering in a Copernican-scale change" in cosmological theory.
