copernican system

İngilizce - İngilizce

copernican system teriminin İngilizce İngilizce sözlükte anlamı: Term used to describe the theory (now a fact) that the earth and other planets revolve around the sun. Named after Polish astronomer Nicolas Copernicus, who challenged the reverse, that means the sun revolved around the earth; (Astronomi) (also Copernican theory) The theory proposed by Nicolaus Copernicus that the sun is the centre of the solar system, with the planets (including the earth) orbiting round it. Compare with Ptolemaic system; the idea, first suggested by Copernicus, that the Earth and the other planets all travel in circles around the sun. Before this it was believed, according to the Ptolemaic system, that the Earth was at the centre of the universe. or Copernican principle Model of the solar system centred on the Sun, with Earth and other planets revolving around it, formulated by Nicolaus Copernicus in the mid 16th century. Having the Sun in this central position explained the apparent motion of planets relative to the fixed stars and was truer than the Earth-centred Ptolemaic system (see Ptolemy). Scientifically, the Copernican system led to belief in a much larger universe than before (because, if the Earth revolved around the Sun, the stars would have to be very distant not to appear to alter their position); more broadly, the Copernican principle is invoked to argue against any theory that would give the solar system a special place in the universe. Dethronement of Earth from the centre of the universe caused profound shock: the Copernican system challenged the entire system of ancient authority and required a complete change in the philosophical conception of the universe; model of the universe developed by Nicolaus Copernicus in which the earth and other planets revolve around the sun; Copernicus' astronomical model in which the Earth rotates around the sun
