Al-Biruni has not helped in understanding Aryabhata's life, for he seemed to believe that there were two different mathematicians called Aryabhata living at the same time. He therefore created a confusion of two different Aryabhatas which was not clarified until 1926 when B Datta showed that al-Biruni 's two Aryabhatas were one and the same person. We know the year of Aryabhata's birth since he tells us that he was twenty-three years of age when he wrote Aryabhatiya which he finished in 499. We have given Kusumapura, thought to be close to Pataliputra (which was refounded as Patna in Bihar in 1541), as the place of Aryabhata's birth but this is far from certain, as is even the location of Kusumapura itself. As Parameswaran writes in [26]:- ... no final verdict can be given regarding the locations of Asmakajanapada and Kusumapura. We do know that Aryabhata wrote Aryabhatiya in Kusumapura at the time when Pataliputra was the capital of the Gupta empire and a major centre of learning, but there have been numerous other places proposed by historians as his birthplace. Some conjecture that he was born in south India, perhaps Kerala, Tamil Nadu or Andhra Pradesh, while others conjecture that he was born in the north-east of India, perhaps in Bengal. In [8] it is claimed that Aryabhata was born in the Asmaka region of the Vakataka dynasty in South India although the author accepted that he lived most of his life in Kusumapura in the Gupta empire of the north. However, giving Asmaka as Aryabhata's birthplace rests on a comment made by

Aryabhata II Born: about 920 in India Died: about 1000 in India Previous (Chronologically) Next Biographies Index Previous (Alphabetically) Next Main index Essentially nothing is known of the life of Aryabhata II. Historians have argued about his date and have come up with many different theories. In [1] Pingree gives the date for his main publications as being between 950 and 1100. This is deduced from the usual arguments such as which authors Aryabhata II refers to and which refer to him. G R Kaye argued in 1910 that Aryabhata II lived before al-Biruni but Datta [2] in 1926 showed that these dates were too early. The article [3] argues for a date of about 950 for Aryabhata II's main work, the Mahasiddhanta, but R Billiard has proposed a date for Aryabhata II in the sixteenth century. Most modern historians, however, consider the most likely dates for his main work as around 950 and we have given very approximate dates for his birth and death based on this hypothesis. See [7] for a fairly recent discussion of this topic. The most famous work by Aryabhata II is the Mahasiddhanta which consists of eighteen chapters. The treatise is written in Sanskrit verse and the first twelve chapters form a treatise on mathematical astronomy covering the usual topics that Indian mathematicians worked on during this period. The topics included in these twelve chapters are: the longitudes of the planets, eclipses of the sun and moon, the projection of eclipses, the lunar crescent, the rising and setting of the planets, conjunctions of the planets with each other and with the stars.

Autores: História da Matemática na Índia Aryabhata I Aryabhata nasceu na Índia em 476. É também conhecido por Aryabhata I, para o destinguir de outro matemático hindu como o mesmo nome que nasceu cerca de 400 anos mais tarde. Aryabhata tinha 23 anos quando escreveu o seu tratado Aryabhatiya terminando-o no ano de 499. O livro contém 118 versos, e está dividido em quatro partes: uma introdução de 10 versos, a segunda parte - Ganitapada - era um resumo da matemática hindu do seu tempo. Nos 32 versos de Ganitapada fala de aritmética, álgebra, trigonometria plana e esférica, fracções continuas e equações do 2º grau. A terceira parte contém 25 versos sobre o cálculo do tempo e modelos planetários, e a parte final contém 50 versos sobre a esfera e eclipses.

Starejši indijski matematik in astronom Ašmaka Indija Āryabhata je najzgodnješi indijski matematik, katerega delo in življenje nam je še znano. Bil je (verjetno) učitelj Bhāskari I., ki je navedel, da je Āryabhata živel v Kusumapuri in jo enačil s Pātaliputro, kar je danes Patna . Arabci so Āryabhato poznali pod imenom Arjehir in je s svojim delom zelo vplival na njih. Okoli leta (499) je napisal matematično delo Āryabhatija v štirih delih. To je edino njegovo znano delo. Je zbirka do tedaj znanih hindujskih astronomskih in matematičnih pravil, pisana v sanskrtu v enako dolgih in rimanih stihih. Vsebuje snov iz astronomije sferične trigonometrije aritmetike algebre in ravninske trigonometrije . Nekatere njegove enačbe so pravilne, nekatere pa tudi ne.
