Aryabhata , also called Aryabhata I or Aryabhata the Elder , born , possibly Ashmaka or Kusumapura, India , astronomer and the earliest Indian mathematician whose work and history are available to modern scholars. He is also known as Aryabhata I or Aryabhata the Elder to distinguish him from a 10th-century Indian mathematician of the same name. He flourished in Kusumapura—near Patalipurta Patna , then the capital of the Gupta dynasty —where he composed at least two works, Aryabhatiya c. Aryabhata became famous as a mathematician and astronomer. In his only surviving work, Aryabhatiya , he covered a wide range of topics, such as extracting square roots , solving quadratic equations , and predicting eclipses.

Timeline Index. Aryabhata is the first of the great astronomers of the classical age of India. Aryabhata gave the world the digit "0" zero for which he became immortal.

His book, the Aryabhatiya, presented astronomical and mathematical theories in which the Earth was taken to be spinning on its axis and the periods of the planets were given with respect to the sun in other words, it was heliocentric. This book is divided into four chapters: the astronomical constants and the sine table mathematics required for computations division of time and rules for computing the longitudes of planets using eccentrics and epicycles the armillary sphere, rules relating to problems of trigonometry and the computation of eclipses.

In this book, the day was reckoned from one sunrise to the next, whereas in his? There was also difference in some astronomical parameters. Aryabhata also gave an accurate approximation for Pi. In the Aryabhatiya, he wrote: "Add four to one hundred, multiply by eight and then add sixty-two thousand. By this rule the relation of the circumference to diameter is given.

As we know zero has formed the basis for the evolution of modern mathematics. Pi has applications in mathematical calculations and various aspects of science and engineering. Ancient India in Vedic Times The Vedic period was a particularly golden period in Indian history, flush with discoveries and inventions in various areas of science, mathematics, arts and culture. And when the western world discovered these concepts, they were hailed as breakthroughs, with no one suspecting that the knowledge was already present in India ages ago.
