According to some researches and studies it was found that at some point of time, Aryabhatta went to Kusumapura for advanced studies and lived there. He studied both Hindu as well as Buddhist tradition there. It is believed that Aryabhatta might have been the head of the Nalanda University, as it had an astronomical observatory at the time. Aryabhatta set up an observatory at the Sun temple in Taregana, Bihar.
Aryabhatta’s major work is comprises of Mathematics and Astronomy. Most of the Aryabhatta’s work can be known from Aryabhatiya. His work in mathematics and astronomy is extensively referred in Indian mathematic literature and able to be part of modern mathematics also. If we see the mathematical section of Aryabhatiya , we will see his work in arithmetic, algebra, plane trigonometry and spherical trigonometry. Along with these major sections of mathematics it also contains the work done by him in continued fraction, quadratic equations, sums-of-power series and sine tables.
The Aryabhatiya also contains description of various astronomy instruments invented by Aryabhatta like the gnomon (shanku-yantra), a shadow instrument (chhaya-yantra), possibly angle-measuring devices, semicircular and circular (dhanur-yantra / chakra-yantra), a cylindrical stick yasti-yantra, an umbrella-shaped device called the chhatra-yantra, and water clocks of at least two types, bow-shaped and cylindrical. He also described the Motion of Solar System, details of Eclipses, Sidereal Rotation periods and Heliocentrism.
It is also believed that some of the Aryabhatta’s work of that time is lost.
