Great Astronomers: Nicolaus Copernicus: Annotated

eBook ( Jan. 21, 2019)
Nicolaus Copernicus (1473-1543) was a scientist and uranologist UN agency developed a comprehensive Copernican model that placed the Sun, instead of the world, at the middle of the universe, contrary to the prevailing thought at his time that placed the world at the middle.
The publication of Copernicus' book, Diamond State revolutionibus orbium coelestium (On the Revolutions of the Celestial Spheres), simply before his death in 1543, is taken into account a significant event within the history of science.
This eBook in short tells the lifetime of Copernicus and explains his key theories: that the rotation of the world causes the apparent daily motion of the objects within the sky, not that the universe rotates round the Earth; that the motion of the planets is healthier explained with the Sun at the middle and therefore the Earth and planets rotating around the sun, instead of the Sun, planets, associate degreed stars rotating round the earth; that the sometimes-retrograde motion of Mars is an illusion because of the world rotating round the Sun faster than Mars will, not that Mars truly reverses its travel.
Although Copernicus properly deduced that the planets rotate round the Sun, he preserved the concept that the orbits were circles. This concept was later overturned by Kepler, who computed that the orbits were elliptical based on accurate measurements of the planets' positions in the sky that were made by Tycho Brahe. (See the volumes concerning astronomer and Brahe during this eBook series on nice Astronomers.)
