geocentric system of the world - this is such a concept structure of the universe, according to which the central body in the universe is our Earth and the Sun, the Moon, as well as all the other stars and planets revolve around it.Earth since ancient times was considered the center of the universe, having a central axis and the asymmetry of the "top - down".According to this concept, the Earth is held in a space with a special support, which in the early civilization is huge elephants, whales and turtles.
geocentric system as a separate concept appeared thanks to ancient Greek mathematician and philosopher Thales of Miletus.He represented as a pillar of the Earth oceans, and suggested that the universe has a center-symmetrical structure and has no preferred direction.For this reason, the Earth, at the center of the cosmos, is at rest without any support.The student Anaximander of Miletus Anaximenes of Miletus distanced himself from some conclusions Thales of Miletus, assuming that the Earth is held in the space of the cosmos by compressed air.
geocentric system for many centuries, is the only correct representation about the world.The point of view of Anaximenes of Miletus shared Anaksogor, Ptolemy and Parmenides.Which view is taken Democritus, history is unknown.Anaximander asserted that the shape of the Earth corresponds to a cylinder whose height is three times smaller than the diameter of its base.Anaksogor, Anaximenes and Levkill argued that the Earth was flat.The first person to put forward the assumption that the Earth is a sphere, was a Greek mathematician, mystic and philosopher - Pythagoras.Next to his point of view joined the Pythagoreans, Parmenides and Aristotle.Thus, the geocentric system was designed in a different context, it appeared the canonical form.
Later canonical form representations geocentric actively developed by astronomers of ancient Greece.They believed that the earth is spherical in shape and occupies a central position in the universe, which also has the shape of a sphere, and that the cosmos revolves around the axis of the world, causing the movement of the heavenly bodies.The geocentric system is constantly perfected new discoveries.So Anaximenes it has been suggested that the higher the position of the light, the greater the period of its revolution around the Earth.The arrangement of the light was built as follows: first there was the Moon from the Earth, for her - the Sun, followed by the Mars, Jupiter and Saturn.Regarding Venus and Mercury there were differences based on the contradiction of their location.Aristotle and Plato placed Venus and Mercury of the Sun, and Ptolemy claimed that they are between the moon and the sun.
geocentric coordinate system used in the modern world in the study of the motion of the moon and spacecraft around the Earth, as well as to determine the geocentric position of the moving celestial bodies around the sun.An alternative theory is geocentric heliocentric system, under which the central celestial body is the Sun and the Earth and other planets revolve around it.
