Bhaskaracharya, also known as Bhaskara II, was one of the most brilliant mathematicians and astronomers of ancient and medieval India. Born in 1114 AD in the Bijjadavida region (modern-day Vijayapura/Bijapur in Karnataka), he belonged to a traditional family of scholars. He learned mathematics and astronomy from his father, Mahesvara, who was a renowned astrologer and scholar.
At the young age of 36 (around 1150 AD), Bhaskaracharya completed his monumental work, the Siddhanta Shiromani. This massive treatise is divided into four major parts, each dealing with specific branches of mathematics and astronomy: Lilavati (arithmetic), Bijaganita (algebra), Grahaganita (astronomy/planetary mathematics), and Goladhyaya (spherical trigonometry and the celestial globe).
-Bhaskaracharya made revolutionary contributions that predated Western discoveries by several centuries. He was the first to state that any number divided by zero becomes infinity (Khahara). In his work Bijaganita, he solved indeterminate quadratic equations of the type $Nx^2 + 1 = y^2$ (later known in the West as Pell's equation) using the ingenious Chakravala method (cyclic method).
Centuries before Sir Isaac Newton and Gottfried Leibniz developed calculus, Bhaskaracharya formulated concepts of differential calculus. He introduced the concept of instantaneous motion (Tatkalika-gati) to measure the precise velocity of planets. Furthermore, in Goladhyaya, he described the Earth's inherent attractive force (Gurutvakarshan), explaining that the Earth pulls objects toward itself due to its natural power long before Western science formalized the law of gravity.
Recognizing his unparalleled genius, Bhaskaracharya was appointed as the head of the historic astronomical observatory at Ujjain, which was the premier center for mathematical and astronomical research in ancient India. He passed away around 1185 AD, leaving behind a profound scientific legacy that continues to inspire the world.
