Nicolaus Copernicus<span> 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. </span>
<span>Publication of De Revolutionibus </span>
<span>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.</span>
Northern Ireland, is situated in the northeastern portion of the island of Ireland. Northern Ireland is bounded on the north and northeast by the North Channel, on the southeast by the Irish Sea, and on the south and west by the Republic of Ireland. It includes Rathlin Island in the North Channel and several smaller offshore islands. It is also known as Ulster, because it comprises six of the nine counties that constituted the former province of Ulster.<span>The total area of Northern Ireland is 14,148 sq km. The shoreline is characterized by numerous irregularities and is about 530 km (about 330 mi) long. The major indentations are Lough Foyle in the north and Belfast, Strangford, and Carlingford loughs in the east. A striking feature of the northern coast is the Giant's Causeway, a rock formation consisting of thousands of closely placed, polygonal pillars of black basalt. The country consists mainly of a low, flat plain in the approximate center of which is Lough Neagh, the largest lake in the British Isles. Other important lakes are Lough Erne and Upper Lough Erne.</span>
