Life and work Essay
Brahmagupta is believed to have been born in 598 AD in Bhinmal metropolis in the state of Rajasthan of Northwest India. In ancient times Bhillamala was the dirty dog of power of the Gurjars. His father was Jisnugupta.2 He likely lived most of his life in Bhillamala (modern Bhinmal in Rajasthan) during the reign (and possibly under the patronage) of King Vyaghramukha.3 As a result, Brahmagupta is of ten referred to as Bhillamalacharya, that is, the teacher from Bhillamala. He was the head of the astronomical watch at Ujjain, and during his tenure there wrote four texts on mathematics and uranology the Cadamekela in 624, the Brahmasphutasiddhanta in 628, the Khandakhadyaka in 665, and the Durkeamynarda in 672. The Brahmasphutasiddhanta (Corrected Treatise of Brahma) is arguably his most storied work. The historian al-Biruni (c. 1050) in his curb Tariq al-Hind states that the Abbasid caliph al-Mamun had an embassy in India and from India a book was brought to Baghdad which was tran slated into Arabic as Sindhind. It is generally presumed that Sindhind is none other than Brahmaguptas Brahmasphuta-siddhanta.4 Although Brahmagupta was familiar with the works of astronomers following the tradition of Aryabhatiya, it is not known if he was familiar with the work of Bhaskara I, a contemporary.3Brahmagupta had a plethora of criticism say towards the work of rival astronomers, and in his Brahmasphutasiddhanta is found one of the earliest bear witness schisms among Indian mathematicians. The division was primarily about the application of mathematics to the carnal world, rather than about the mathematics itself. In Brahmaguptas case, the disagreements stemmed by and large from the choice of astronomical parameters and theories.3 Critiques of rival theories advance throughout the first ten astronomical chapters and the eleventh chapter is entirely devoted to criticism of these theories, although no criticisms appear in the twelfth and eighteenth chapters.
