Brahmagupta

Brahmagupta, born in the year five hundred ninety-eight, was a pioneering Indian mathematician and astronomer whose contributions have left an indelible mark on the fields of mathematics and astronomy.

He is renowned for being the first to formalize the concept of zero, a revolutionary idea that transformed mathematical thought. His seminal works include the Brāhmasphuṭasiddhānta, a theoretical treatise dated six hundred twenty-eight, and the Khandakhadyaka, a practical text from six hundred sixty-five.

In addition to his groundbreaking work on zero, Brahmagupta was the first Indian scholar to articulate the concept of gravity as an attractive force, coining the term 'gurutvākarṣaṇam' in Sanskrit. His insights into the nature of gravity and motion were ahead of his time.

Furthermore, he provided the first clear description of the quadratic formula in his main work, the Brāhmasphuṭasiddhānta, showcasing his profound understanding of algebraic equations.
