Bhaskara II, also known as Bhaskaracharya, was one of the most well known and popular astronomers of 12th century who has been popularly known for his contribution in the field of astronomy where he has related the science of astronomy with more specific mathematical formulae which included algebra, pure arithmetic, Trignometry as well as old mathematic formula of Calculus. Bhaskara II born in 1114 AD in Bijapur
district of Karnataka
on the Western coast line of India wrote a number of books which can be compared on the same intensity with his predecessors in case of calculating the time, direction and place, the eclipse, setting and the conjunction of the planets.
Bhaskara II has been popularly known for his contribution which he made in the field of astronomy and mathematics. His observations are mainly included in his most celebrated work known as Siddhanta Shiromani which is further divided into four parts known as Lilavati, Bijaganita, Grahaganita and Goladhyaya. While Siddhanta Shiromany is written in Sanskrit it mainly includes the study of Arithmetic, Algebra, Mathematics of Planets and the study of Sphere. Bhaskara`s work on calcus can be dated even earlier tanthe work of Newton and Leibniz where Bhaskara has been mainly credited for introducing the study of calculus in computing the accuracy of the movement of the planets.
Bhaskara II compiled another book which included his own commentary on which he calls Vasanabhashya which was published with another work on the planetary movement known as Karanakutuhala. All his work both in its completeness as well as parts has been published in large numbers in all over the country which has invited large number of translations from a number of scholars of the medieval period.
Thus, Bhaskara II has been one of the most popular astronomer as well as mathematician of 12th century who could similar level of accurate calculations as well as prediction like his predecessors which could help him to calculate the right position of the Earth its longitude, and derive authentic knowledge regarding the time, distance and place.
