The first of the Hindu mathematicians was ARYABHATTA who lived in or near the present city Patna on the Ganges, in Bihar state of India. He was born in Kusumpuram and wrote his famous work The Aryabhattiya in 499A.D at the age of 23. In addition to the other contributions of Aryabhatta this voluminous work is enough to place him among the first ranking astronomers and the mathematicians of the world.
From the writings of Bhaskara, it appears that Aryabhatta took up the profession of a teacher. He earned fame as a great scholar and a teacher of astronomy.
Aryabhatta's contribution to the field of mathematics is extremely significant. He gave a systematic approach to Arithmetic, Algebra and Trigonometry. He was the 1st mathematician who gave the value of ∏ (pi) correct upto four decimal places.
Aryabhatta gave a method to find the cube root of numbers and dealt with arithmetic,geometric and indeterminate equations in algebra. He dealt with square,cube,triangle,trapezium,circle and sphere in geometry.
Aryabhatta occupies the 1st position among the astronomers of not only India but the whole world by telling that Earth is moving around the Sun. This knowledge about the Earth given by Aryabhatta was much beyond the imagination of scholars even after 1000 years of Aryabhatta.
However, Parthdak Swami(860A.D) and Copernicus(1600A.D) supported Aryabhatta and his Principle of rotation of the Earth around the Sun.
