Aryabhata  ( IAST Āryabhaṭa Sanskrit आर्यभट ) (476–550  CE ) was the first in the line of great  mathematician - astronomers from the classical age of  Indian mathematics  and  Indian astronomy . His most famous works are the  Āryabhaṭīya  (499 CE, when he was 23 years old) and the  Arya-siddhanta . Aryabhata mentions in the   Aryabhatiya   that it was composed 3,630 years into the   Kali Yuga , when he was 23 years old. This corresponds to 499 CE, and implies that he was born in 476

Aryabhata was born in Taregna (literally, song of the stars), which is a small town in Bihar, India, about 30 km (19 mi) from Patna (then known as Pataliputra), the capital city of Bihar State. Evidences justify his birth there. In Taregna Aryabhata set up an Astronomical Observatory in the Sun Temple 6th century[1].

There is no evidence that he was born outside Patliputra and traveled to Magadha, the centre of instruction, culture and knowledge for his studies where he even set up a coaching institute. [3]  However, early Buddhist texts describe Ashmaka as being further south, in dakshinapath or the Deccan, while other texts describe the Ashmakas as having fought Alexander.

[1]  Kalam played a pivotal organizational, technical and political role in India 's  Pokhran-II  nuclear tests in 1998, the first since the original nuclear test by India in 1974. Kalam has even been circled with various controversies as many scientific experts called him a man with no authority over "nuclear physics" and a man who just carried on the works of Homi J. Bhabha and Vikram Sarabhai. [2]

He is currently a visiting professor at Indian Institute of Management Ahmedabad and Indian Institute of Management Indore,Chancellor of Indian Institute of Space Science and Technology Thiruvananthapuram, a professor of Aerospace Engineering at Anna University (Chennai), JSS University (mysore), and an adjunct/visiting faculty at many other academic and research institutions across India.
