Aryabhata ( ISO: Āryabhaṭa) or Aryabhata I [3] [4] (476–550 CE) [5] [6] was the first of the major mathematician-astronomers from the classical age of Indian mathematics and Indian astronomy. His works include the Āryabhaṭīya (which mentions that in 3600 Kali Yuga , 499 CE, he was 23 years old) [ 7 ] and the Arya- siddhanta .
Following the Ganitapada, the next section is the "Kalakriya" or "The Reckoning of Time." In it, Aryabhata divides up days, months, and years according to the movement of celestial bodies. He divides up history astronomically; it is from this exposition that a date of AD 499 has been calculated for the compilation of the Aryabhatiya. [4]
Note that it may still be copyrighted in jurisdictions that do not apply the rule of the shorter term for US works (depending on the date of the author's death), such as Canada (70 years p.m.a.), Mainland China (50 years p.m.a., not Hong Kong or Macao), Germany (70 years p.m.a.), Mexico (100 years p.m.a.), Switzerland (70 years p.m.a.), and other countries with individual treaties.
Further translation of Indian works on astronomy was completed in China by the Three Kingdoms era (220–265 CE). [49] However, the most detailed incorporation of Indian astronomy occurred only during the Tang dynasty (618–907 CE) when a number of Chinese scholars – such as Yi Xing – were versed both in Indian and Chinese astronomy .

Aryabhata was India's first satellite, [2] named after the astronomer. [3] It was launched on 19 April 1975 [ 2 ] from Kapustin Yar , a Soviet rocket launch and development site in Astrakhan Oblast using a Kosmos-3M launch vehicle.
Aryabhata used this number system for representing both small and large numbers in his mathematical and astronomical calculations. This system can even be used to represent fractions and mixed fractions. For example, nga is 1 ⁄ 5, nja is 1 ⁄ 10 and jhardam (jha=9; its half) = 4 + 1 ⁄ 2. [further explanation needed]
Aryabhata gave the algorithm for solving the linear Diophantine equation in verses 32–33 of Ganitapada of Aryabhatiya. [1] Taking Bhāskara I's explanation of these verses also into consideration, Bibhutibbhushan Datta has given the following translation of these verses: Description of Kuttaka as given by Aryabhata in Aryabhatiya
Like Brahma-gupta, Varāhamihira rejects Aryabhata's view (now universally accepted) that the earth revolves around the sun. [13] Utpala suggests that Varāhamihira wrote an abridged version of the Pancha-siddhantika, but that work is now lost. [8] Shatananda based his Bhasvati-karana (c. 1098 CE) on the Surya Siddhanta section of the Pancha ...
