Question

hey friendz plz provide me small paragraph on great mathematicians (5)

Answer 1

Aryabhata (Sanskrit: आर्यभट; IAST: Āryabhaṭa) or Aryabhata I[2][3] (476–550 CE)[4][5] was the first of the major mathematician-astronomers from the classical age of Indian mathematics and Indian astronomy. His works include the Āryabhaṭīya (499 CE, when he was 23 years old)[6] and the Arya-siddhanta.

BiographyName

While there is a tendency to misspell his name as "Aryabhatta" by analogy with other names having the "bhatta" suffix, his name is properly spelled Aryabhata: every astronomical text spells his name thus,[7] including Brahmagupta's references to him "in more than a hundred places by name".[8] Furthermore, in most instances "Aryabhatta" would not fit the metre either.[7]

Time and place of birth

Aryabhata mentions in the Aryabhatiya that it was composed 3,600 years into the Kali Yuga, when he was 23 years old. This corresponds to 499 CE, and implies that he was born in 476.[5] Aryabhata called himself a native of Kusumapura or Pataliputra (present day Patna).[1]

Other hypothesis

Bhāskara I describes Aryabhata as āśmakīya, "one belonging to the Aśmaka country." During the Buddha's time, a branch of the Aśmaka people settled in the region between the Narmada and Godavari rivers in central India.[7][9]

It has been claimed that the aśmaka (Sanskrit for "stone") where Aryabhata originated may be the present day Kodungallur which was the historical capital city of Thiruvanchikkulam of ancient Kerala.[10] This is based on the belief that Koṭuṅṅallūr was earlier known as Koṭum-Kal-l-ūr ("city of hard stones"); however, old records show that the city was actually Koṭum-kol-ūr ("city of strict governance"). Similarly, the fact that several commentaries on the Aryabhatiya have come from Kerala has been used to suggest that it was Aryabhata's main place of life and activity; however, many commentaries have come from outside Kerala, and the Aryasiddhanta was completely unknown in Kerala.[7] K. Chandra Hari has argued for the Kerala hypothesis on the basis of astronomical evidence.[11]

Aryabhata mentions "Lanka" on several occasions in the Aryabhatiya, but his "Lanka" is an abstraction, standing for a point on the equator at the same longitude as his Ujjayini.[12]

Education

It is fairly certain that, at some point, he went to Kusumapura for advanced studies and lived there for some time.[13] Both Hindu and Buddhist tradition, as well as Bhāskara I (CE 629), identify Kusumapura as Pāṭaliputra, modern Patna.[7] A verse mentions that Aryabhata was the head of an institution (kulapa) at Kusumapura, and, because the university of Nalanda was in Pataliputra at the time and had an astronomical observatory, it is speculated that Aryabhata might have been the head of the Nalanda university as well.[7]Aryabhata is also reputed to have set up an observatory at the Sun temple in Taregana, Bihar.[14]

Answer 2

India is a country blessed with great mathematicians and scientists. In the rich heritage that India has, one such great mathematician is Srinivasa Ramanujan. He was born on December 22, 1887 at Kumbakonam in the city of Chennai, erstwhile Madras. He came from a very poor family.

At the age of five, Srinivasa Ramanujan made his first appearance in school as a student. It was only a matter of time before it came to be known that he had extraordinary talent. He showed flashes of brilliance which were not to seen in any ordinary kid at that age. Srinivasa Ramanujan

completed his primary education in a couple of years and then went to Town High School for further studies.

He showed extraordinary liking for mathematics. When he was yet in school, he mathematically calculated the approximate length of earth’s equator. He very clearly knew the values of the square root of two and the pie value. At the age of 16, Srinivasa

Ramanujan got scholarship. But his love only for mathematics cost him the scholarship as he neglected and failed in other subjects.

The scholarship was of a great help to him as he came from a poor family. But the love of mathematics was so acute, that he did not know any other thing in the world. Srinivasa Ramanujan literally breathed mathematics day in and day out.

His loss of scholarship was a great blow to Ramanujan. He could not afford to study on his own. Poverty got the better of him and he had to find work and leave studies for good.

However, where there is a will, there is a way. He found a job of an accounts clerk in the office of the Madras Port Trust. That was good to support him. But more importantly, it was the relief that he could get back to mathematics again.
