Conclusion
Aryabhata changed his world as well as ours through his discoveries in the field of mathematics as well as astronomy. Without Aryabhata many of the things we take for granted may not have been here. His estimate of pi, sidereal year, and use of zero greatly changed the world. Each one of his achievements had a great impact. Aryabhata deserves to win the Nobel Prize for all the tremendous work he did that changed his world as well as ours.
