Biography
Aryabhata was a pioneering 5thcentury Indian mathematician and astronomer who revolutionized scientific thought with groundbreaking work in trigonometry, algebra, and celestial mechanics. He calculated pi to four decimal places (3.1416) and provided compelling evidence for Earth's rotation, concepts that wouldn't gain widespread acceptance in Europe for over a thousand years. His mathematical innovations established foundational principles still taught today.
