Bhaskaracharya
Mathematician and astronomer Sage Bhaskaracharya is well-known. He has published a number of books and proposed a number of ideas in math and astronomy that are even older than many other discoveries and inventions made by western scientists. He has demonstrated a number of theorems, similar to Pythagoras. He gave numbers, such as quadrillion and even more, new names. He has written a number of books on quadratic equations. His calculus works are regarded as highly intellectual. He recommended that the earth isn't level, and, surprisingly, upheld his thoughts with a few hypothesizes. He even provided the proposed orbital distance and the distance between each planet. He was in charge of India's educational hub, the "Astronomical Observatory in Ujjain." He has carried out his calculations and experiments with a variety of instruments. He emphasized that "Mind" is the great master and that it could use its mind to carry out a number of research and experimentations.
