Nicolaus copernicus was the first astronomer to formulate a scientifically-based heliocentric cosmology that displaced the earth from the center of the universe. his epochal book, "de revolutionibus orbium coelestium" - on the revolutions of the celestial spheres - is often regarded as the starting point of modern astronomy and the defining epiphany that began the scientific revolution. publication of de revolutionibus although greek, indian and muslim savants had published heliocentric hypotheses centuries before copernicus, his publication of a scientific theory of heliocentrism, demonstrating that the motions of celestial objects can be explained without putting the earth at rest in the center of the universe, stimulated further scientific investigations and became a landmark in the history of modern science that is known as the copernican revolution. among the great polymaths of the renaissance, copernicus was a mathematician, astronomer, physician, classical scholar, translator, catholic cleric, jurist, governor, military leader, diplomat and economist. among his many responsibilities, astronomy figured as little more than an avocation - yet it was in that field that he made his mark upon the world.

johnny depp, my favorite actor
i think johnny depp is the coolest actor in the hollywood. he acts so well in his every movies. born in owensborn, kentucky on june 9,1963, johnny depp was raised in florida.the young john cristopher depp really want to be a rock musician. but, this brought him to the movie world. his first film debut was a nightmare on elm street in 1984.johnny depp has played many characters in his career. but the most interesting action for me is pirates of the caribbean : the curse of the black pearl. he acted so well in that movie. he was so perfect being a charming, conniving roughish captain. i think he is the only actor who can do that.in his real life he was married with lori anne allison in 1983 but then divorced in 1985. now, he’s living with vanessa paradise, a french singer and actress. they have to children, lily rose melody(1999) and jack (2002). he has dated several female celebrities and has been engaged to jennifer grey, wyona ryder and kate moss.depp is now one of the most versatile actors of his day in hollywood. well done, depp. keep on doing your best. we are waiting for your next movie.
