Hello
Do you you who is the first person (an Indian) to propose that the earth is spherical and rotated on its axis?
It was Aryabhatta. He was an astronomer and one of the earliest Indian mathematicians and wrote Aryabhatiya in 499 A.D, which was written in verse couplets and summarized mathematics known in his time. He was one of the first to use Algebra also.
