accomplishments of aryabhatta
Answers
Aryabhata was an acclaimed mathematician-astronomer. He was born in Kusumapura (present day Patna) in Bihar, India. His contribution to mathematics, science and astronomy is immense, and yet he has not been accorded the recognition in the world history of science. At the age of 24, he wrote his famed “Aryabhatiya”. He was aware of the concept of zero, as well as the use of large numbers up to 1018. He was the first to calculate the value for ‘pi’ accurately to the fourth decimal point. He devised the formula for calculating areas of triangles and circles. He calculated the circumference of the earth as 62,832 miles, which is an excellent approximation, and suggested that the apparent rotation of the heavens was due to the axial rotation of the earth on its axis. He was the first known astronomer to devise a continuous counting of solar days, designating each day with a number. He asserted that the planets shine due to the reflection of sunlight, and that the eclipses occur due to the shadows of moon and earth. His observations discount the “flat earth” concept, and lay the foundation for the belief that earth and other planets orbit the sun
Aryabhata is credited to have set up an observatory at the Sun temple in Taregana, Bihar.
Some sources suggest that Kerala was Aryabhata's main place of life and activity but others refute this statement.
He served as the head of an institution (kulapa) at Kusumapura and might have also been the head of the Nalanda university.
Some scholars claim that the Arabic text ‘Al ntf’ or ‘Al-nanf’ is a translation of one of his works.
His most famous text, ‘Aryabhatiya’, consists of 108 verses and 13 introductory verses.
Aryabhata did not use the Brahmi numerals; he used letters of the alphabet to denote numbers.
It is probable that he might have come to the conclusion that 'pi' is irrational.
He discussed the concept of ‘sine’ in his work by the name of “ardha-jya”, which literally means "half-chord".
Calendric calculations devised by Aryabhata are used for fixing the ‘Panchangam’ (the Hindu Calendar).
He correctly stated that the earth rotates about its axis daily.
