Copernicus
Nicolaus Copernicus was the scientist who wrote the book "De Revolutionibus Orbium Coelestium" (On the Revolutions of the Celestial Spheres) in 1543, in which he proposed the heliocentric model of the universe with the sun at the center.
It is about the Revolutions of the Heavenly Spheres, it is by Nicolaus Copernicious.
In 1543 Nicolas Copernicus changed the way the universe was viewed. He published a paper called De Revolutionibus Orbium Coelestium (The Revolution of Celestial Spheres). In this paper, he told of a whole new universe and galaxy that no one had known before. He introduced the heliocentric model.
Nicolaus Copernicus, in 1543 , proposed his version of the heliocentric (Sun-centered) organization of the universe.(from De revolutionibus orbium coelestium)Finally we shall place the Sun himself at the center of the Universe.All this is suggested by the systematic procession of events andthe harmony of the whole Universe, if only we face the facts,as they say, 'with both eyes open'.
Nicolaus Copernicus was a Renaissance astronomer and the first person to formulate a comprehensive heliocentric cosmology, which displaced the Earth from the center of the universe. Copernicus dedicated the book to Paul III who was known for his astrological predilection. De Revolutionibus was a book and when he published it the gov't didn't want to get rid of the Earth-Centered (Geocentric) Theory so before they published De Revolutionibus, they wrote in the beginning of the book that the stuff written in the book was all fictional. The book was published in March 1543.
The publication of Copernicus's book, "De Revolutionibus Orbium Coelestium," was important because it presented the heliocentric model of the universe, placing the Sun at the center with planets orbiting around it. This challenged the geocentric view that had prevailed for centuries and laid the foundation for modern astronomy and our understanding of the universe. Copernicus's work revolutionized our understanding of the cosmos and paved the way for later scientific advancements.
That the universe was heliocentric, not geocentric. He disproved the fact that everything revolved around the Earth (geocentric). Instead he came up with the heliocentric theory; everything revolves around the sun.
He was Mexican - That is answer is wrong. In 1532 Copernicus had basically completed his work on the manuscript of De revolutionibus orbium coelestium; but despite urging by his closest friends, he resisted openly publishing his views, not wishing, as he confessed, to risk the scorn "to which he would expose himself on account of the novelty and incomprehensibility of his theses."
Nicolaus Copernicus showed that our universe is heliocentric.
The concept of helio centric motion of the earth and planets was proposed by Nicolaus Copernicus (1473-1543) in his works 'De Revolutionibus Orbium Coelestium'- (About the revolutions of The heaveanly Spheres.).
