Popular search engine Google doodle on Tuesday celebrated the 540th birth anniversary of Renaissance mathematician and astronomer Nicolaus Copernicus by decorating its homepage with an animated doodle.
Netizens could see the sun placed at the centre of the universe while other planets are revolving around it. The moon is revolving around the earth.
The doodle also features the then known other five planets - Mercury, Venus, Mars, Jupiter and Saturn - revolving around the sun.
In the doodle, the sun has replaced the second ´o´ of the word Google.
Born on 1473 at the city of Toruń (Thorn) in the province of Royal Prussia in the Crown of the Kingdom of Poland, Nicolaus Copernicus formulated a comprehensive heliocentric model which placed the Sun, rather than the Earth, at the center of the universe.
The publication of Copernicus´ epochal book, De revolutionibus orbium coelestium (On the Revolutions of the Celestial Spheres), just before his death in 1543, is considered a major event in the history of science. It began the Copernican Revolution and contributed importantly to the rise of the ensuing Scientific Revolution.
