Aryabhata's Aryabhatiya

Aryabhatiya is an ancient Indian mathematical and astronomical treatise written by the scholar Aryabhata around 500 CE. It compiles mathematical techniques, including methods for solving problems related to angles, circles, and spheres, and presents early concepts of zero and place value. It describes planetary motions, eclipses, and the Earth's rotation with remarkable accuracy for its time. The text significantly influenced Indian mathematics and astronomy, and many of its ideas laid foundations later adopted by other cultures. Overall, Aryabhatiya is a profound work combining practical calculations with theoretical insights into astronomy.
