He calculated the time taken by the earth to orbit the sun hundreds of years before the astronomer Smart; Time taken by earth to orbit the sun: 365.258756484 days. Born in the obscure village of Vijjadit (Jalgaon) in Maharastra, Bhaskaracharya’s mathematical works called “Lilavati” and “Bijaganita” are considered to be unparalleled. In his treatise “Siddhant Shiromani” he writes on planetary positions, eclipses, cosmography, mathematical techniques and astronomical equipment. In the “Surya Siddhanta” he makes a note on the force of gravity: “Objects fall on earth due to a force of attraction by the earth. Therefore, the earth, planets, constellations, moon, and sun are held in orbit due to this attraction.” Bhaskaracharya was the first to discover gravity, hundreds of years before Sir Isaac Newton.
