What did Aryabhatta invented
Answers
.....Aryabhata gave the world the digit "0" (zero) for which he became immortal. His book, the Aryabhatiya, presented astronomical and mathematical theories in which the Earth was taken to be spinning on its axis and the periods of the planets were given with respect to the sun (in other words, it was heliocentric).
Aryabhata discovered an approximation of pi, 62832/20000 = 3.1416. He also correctly believed that the planets and the Moon shine by reflected sunlight and that the motion of the stars is due to Earth's rotation.
