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.
On the Universe De mundo (Greek: Περὶ Κόσμου ), known in English as On the Universe, is the work of an unknown author who wrote under the name of Aristotle. Because of this, the author is referred to as a Pseudo-Aristotle. The date of the work is uncertain; it has been argued that it was composed before 250 BC or between 350 and 200 BC. It is found under the Bekker numbers 391–401. It should not be confused with "On the Heavens".
