Happy Birthday Copernicus!
To know that we know what we know, and to know that we do not know what we do not know, that is true knowledge. ~ Nicolaus Copernicus
Born Feb 19, 1473 – Died May 24, 1543, Nicolaus Copernicus was a Renaissance mathematician and astronomer who’s heliocentric theory first proposed a mathematical model of the solar system with the sun at its center as opposed to the Earth. Copernicus along with Galileo Gallilee and Johannes Kepler are generally considered the fathers of modern astronomy. The publications, in 1543, of Copernicus’s De revolutionibus orbium coelestium (On the Revolutions of the Heavenly Spheres), along with Andreas Vesalius‘s De humani corporis fabrica (On the Fabric of the Human body) is often cited as marking the beginning of the Scientific Revolution.
