Antiquity. Tszu Chunchzhi

It is necessary to note and Tszu Chunchzhi (420-500) which has invented and has introduced a calendar, has calculated size of lunar month and cycle times of planets with surprising the then accuracy. On the basis of supervision it has defined duration drakonicheskogo month in 27,21223 days that differs from true value of all on one hundred-thousandth.

Whether At calendar drawing up ' Damin ' it had been considered the phenomenon pretsessii, opened in China irrespective of Europeans in the beginning of our era, and, as consequence, - a difference between duration tropical and sidereal year. The calendar has been entered into action by the son of the scientist - Tszu Henchzhi.

Approximately for the millenium has outstripped the time And the Blue (683-727) which has opened own movements of stars, having expressed together with Ljan Litszanem opinion on variability of distances between ' motionless ' stars. And the Blue has designed bronze armilljar th sphere for definition of co-ordinates of heavenly bodies, and also has made the star globe rotating by means of water which movement corresponded to daily movement of heavenly sphere.

The Indian astronomer and mathematician Ariabhata (476-?) Pataliputry was born in Kusumapure near. Us has reached only one or the other his compositions - ' Ariabhatiam ' where the mathematical data necessary for astronomical calculations, and also decisions of the equations, including the linear equation with two unknown persons, the way similar to a modern way of continuous fractions are resulted. Ariabhata to an explanation of non-uniformity of an apparent motion of planets has applied the theory epitsiklov.

He also has stated a guess that rotation of heavens is the seeming phenomenon, actually the Earth about the axis rotates, substituting a surface under beams of the Sun and stars. Through 1,5 thousand years one of the first Indian artificial companions of the Earth has been named by a name of Ariabhaty.
