India has been a cradle of mathematics and astronomy since ancient times. Among the many brilliant scholars India has produced, Bhaskaracharya II, also known as Bhaskara II, stands as a towering figure in the world of science and mathematics. His exceptional contributions laid the foundation for many modern mathematical and astronomical principles long before the Western world even discovered them. Here we explore his life, works, and legacy of this great Indian mathematician and astronomer.
Who Was Bhaskaracharya II?
Have you ever wondered who laid the early foundations of advanced mathematics and astronomy in India, the answer lies in the life and work of Bhaskaracharya II – a great scholar whose genius continues to influence science today.
Bhaskaracharya II, also known as Bhaskara II or Vidwan Bhaskara, was born in 1114 AD in a small village called Vijjadavida (present-day Bijapur, Karnataka, India). He was born in a Brahmin family which was famous for its strong tradition of education and spiritual knowledge. His father, Maheshwara, was a reputed astrologer and mathematician, and it was under his guidance that the mind of the young Bhaskara was molded in the ancient Vedic sciences.
From an early age Bhaskara displayed an extraordinary aptitude for numbers, astronomical patterns and abstract thinking. His home environment, full of scrolls, debates and calculations, provided the perfect atmosphere to nurture a future genius. He did not just learn; he absorbed complex knowledge of astronomy (jyotish) and mathematics (ganit) and soon surpassed his teachers.
As Bhaskara’s intellect matured, his works reflected not just calculations and observations, but also philosophy, logic and poetic beauty. His extraordinary brilliance earned him the title of ‘Acharya’, which means “great teacher” in Sanskrit. This is why history remembers him as Bhaskaracharya – a name that signifies both knowledge and respect.
What makes Bhaskaracharya II truly remarkable is that he had made important mathematical and astronomical discoveries centuries before they were discovered in Europe. In fact, his ideas anticipated many theories of calculus, algebra and planetary motion that became mainstream in the West much later.
About Bhaskaracharya II
- Bhaskara’s birth date is recorded as 1114 AD precisely because he is mentioned in his texts.
- Bhaskara II rose to the position of head of the famous astronomical observatory at Ujjain, the center of ancient Indian science.
- Many modern scholars consider him to be one of the earliest known thinkers to explore concepts such as calculus, long before Newton or Leibniz.
Major Works of Bhaskara II
Bhaskaracharya’s magnum opus is “Siddhanta Shiromani”, a comprehensive treatise that reflects his deep understanding of both mathematics and astronomy. This masterpiece is divided into four parts:
- Lilavati (Arithmetic)
- Bijaganita (Algebra)
- Grahaganita (Mathematics of Planets/Astronomy)
- Goladhyaya (Spherical Astronomy)
These works stand out not just for their content but also for their elegant presentation in poetic Sanskrit verse.
Lilavati: The Foundation of Arithmetic
The Lilavati work is perhaps the most famous of all his works. It explores various mathematical concepts, such as:
- Arithmetic operations
- Fractions
- Square roots and cube roots
- Rule of three
- Interest calculations
- Geometry and area formulas
What makes Lilavati special is that it uses methods to solve real-life problems, often written in a poetic and charming way. According to legends, Bhaskar named this book after his daughter Lilavati and wrote it to console her when she missed her wedding due to wrong timing.
Bijaganita: The Science of Algebra
In Bijaganita, Bhaskara II takes algebra to new heights:
- Solving quadratic equations
- Introducing the concept of zero and infinity
- Interpreting positive and negative numbers
- Using Chakravarti method to solve indeterminate equations
His algebraic techniques were centuries ahead of European mathematicians, and the Chakravarti method was later praised by the famous German mathematician Carl Friedrich Gauss.
Astronomical Brilliance: Grahaganita and Goladhyaya
Bhaskaracharya was also a pioneer of astronomy. The astronomical sections of his Siddhanta Shiromani – Grahaganita and Goladhyaya – deal with the following:
- Planetary motions
- Eclipses
- Celestial spheres
- Time calculations
- Solar and lunar eclipses
His calculation of the Earth’s revolution around the Sun, 365.2588 days, was incredibly precise, differing only slightly from today’s accepted value of 365.25636 days.
Key Contributions of Bhaskaracharya II to Mathematics
Concept of zero: He was among the first to clearly explain the mathematical properties of zero.
He explored the concept of infinity and its mathematical significance.
Calculus theory: Some historians believe that Bhaskara’s work hints at the concepts of differential calculus centuries before Newton and Leibniz.
Indeterminate equations and indeterminate equations: He dealt systematically with irrational numbers and complex equations.
Algebraic notation: He used symbolic representations for unknown quantities.

Legacy and Impact
Bhaskaracharya II’s legacy is enormous and enduring. His books were used as textbooks in India and Middle Eastern countries for many centuries. His clear explanation of complex subjects, poetic style, and practical approach made his works invaluable to learners and scholars.
In honour of his contributions, the Indian Space Research Organization (ISRO) named India’s satellite studying the solar corona “Bhaskar”.
Conclusion
Bhaskaracharya II was not just a mathematician or astronomer – he was a visionary genius whose work laid the foundations of modern science. His life is a testament to India’s rich heritage of knowledge and wisdom. By understanding and appreciating his work, we not only honor a great scholar, but also draw inspiration from a time when India led the world in intellectual achievements.
