Birthday

On this date, in the year of our Lord 1473, Astronomer Nicolaus Copernicus was born in Torun,Poland. In Polish, his name was Mikolaj Kpernik.

It was he who developed the theory that the earth is a moving planet. As a result, he is considered the founder of present-day astronomy. Copernicus skillfully applied his new idea in his masterpiece, Concerning the Revolutions of the Celestial Spheres (1543). Copernicus' theory also laid the foundations for the telescopic discoveries of Galileo, the planetary laws of Johannes Kepler, and the gravitation principle of Sir Isaac Newton.
