Let the sun shine . . .

Today is the birthday of a great polymath, Nicolaus Copernicus (February 19, 1473 – May 24, 1543). He was a mathematician, astronomer, jurist, physician, classical scholar, governor, administrator, diplomat, economist, artist, translator and soldier. 

Nicolaus Copernicus is remembered for the Copernican heliocentrism theory of the solar system. He provided the first modern formulation of a heliocentric (sun-centered) theory of the solar system in his epochal book, De revolutionibus orbium coelestium (On the Revolutions of the Celestial Spheres).

"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
