National Mathematics Day is celebrated every year on 22 December to mark the birthday of Srinivasa Ramanujan, who is reckoned as one of the greatest mathematicians that India has ever produced. Mathematics has been a significant field since ancient times in India, having great cultural as well as academic value. In the present era, a number of Indian mathematicians have contributed to the world of mathematics right from ancient explorations.
This blog will pay tribute to twenty of India’s most famous mathematicians, exploring the discoveries they made, the lives they led, and the role they played in shaping the course of mathematics.
1. Srinivasa Ramanujan (1887–1920)
Srinivasa Ramanujan, whose birthday is commemorated as National Mathematics Day, is undoubtedly the most celebrated Indian mathematician. Ramanujan worked together with G.H. Hardy and came up with more than 3,900 mathematical solutions including the finite and infinite series and theories on numbers among other disciplines.
Key Contributions:
- Ramanujan’s Theta Function
- Partition functions and infinite series
2. Aryabhata (476 CE)
Aryabhata is considered one of the first great mathematicians of the Indian subcontinent; he is credited with having given the world the numeral zero and an estimation of the value of pi (π). Aryabhata was one of the most renowned scholars of ancient India whose book Aryabhatiya gave the initial framework to Indian astronomy and mathematics.
Key Contributions:
- Sine tables in trigonometry
- Methods for solving quadratic equations
3. Brahmagupta (598–668 CE)
Brahmagupta, often regarded as the father of algebra, was the first to define zero as a number. He also introduced rules for arithmetic operations involving zero and negative numbers.
Key Contributions:
- Brahmasphutasiddhanta
- Formulas for cyclic quadrilaterals
4. Bhaskara I (600–680 CE)
A 7th-century mathematician, Bhaskara I was one of the earliest to use a symbol for zero in mathematical calculations. He also wrote commentaries on Aryabhata’s works.
Key Contributions:
- Approximation of sine functions
- Development of mathematical astronomy
5. Bhaskara II (1114–1185 CE)
Popularly known as Bhaskaracharya, Bhaskara II was a pioneer in calculus and algebra. His works include Lilavati, which remains a cornerstone of mathematical education in India.
Key Contributions:
- Concepts of differentiation and integration
- Solutions to quadratic, cubic, and quartic equations
6. Ramachandra Rao (1870–1936)
Ramachandra Rao was an important figure who recognized Ramanujan’s genius and helped him connect with the mathematical community. While not a mathematician in the traditional sense, his contributions to promoting mathematics were vital.
7. Narayana Pandit (1340–1400 CE)
Narayana Pandit’s work Ganita Kaumudi provided solutions to magic squares and combinatorics. He is considered a pioneer in mathematical puzzles and recreational mathematics.
8. P.C. Mahalanobis (1893–1972)
P.C. Mahalanobis, the founder of the Indian Statistical Institute, made significant contributions to statistics, particularly with the Mahalanobis distance.
Key Contributions:
- Sampling techniques
- Development of statistical methods for economic planning
9. D.R. Kaprekar (1905–1986)
Kaprekar discovered fascinating properties of numbers and is best known for the Kaprekar constant (6174). His work on recreational mathematics continues to inspire enthusiasts worldwide.
10. Harish-Chandra (1923–1983)
A theoretical physicist and mathematician, Harish-Chandra made groundbreaking contributions to representation theory and harmonic analysis.
11. Shakuntala Devi (1929–2013)
Popularly known as the “Human Computer”, Shakuntala Devi was celebrated for her extraordinary mental arithmetic skills. She even found a place in the Guinness World Records for her achievements.
12. C.R. Rao (1920–2023)
Calyampudi Radhakrishna Rao, or C.R. Rao, is one of the greatest statisticians of the 20th century. His contributions to multivariate analysis are widely recognized.
Key Contributions:
- Rao-Blackwell Theorem
- Contributions to linear statistical inference
13. Manjul Bhargava (1974–present)
A Fields Medalist, Manjul Bhargava is renowned for his work in number theory. His innovative approaches have transformed algebraic geometry.
14. K.S. Chandrasekharan (1920–2017)
Chandrasekharan’s work in analytic number theory and modular forms has been instrumental in advancing modern mathematics.
15. Satyendra Nath Bose (1894–1974)
Although known more for his work in physics, Bose’s contributions to mathematics, particularly in quantum statistics, are monumental.
16. T. Vijayaraghavan (1902–1955)
An expert in algebraic geometry, T. Vijayaraghavan is known for his work on sequences and metric geometry.
17. Vashishtha Narayan Singh (1942–2019)
Often called the “Indian Einstein,” Vashishtha Narayan Singh contributed significantly to number theory and algebra.
18. R. Balasubramanian (1949–present)
A renowned mathematician in the field of number theory, R. Balasubramanian’s contributions include work on the Riemann zeta function.
19. Neena Gupta (1984–present)
An emerging mathematician, Neena Gupta has gained international recognition for her work in algebraic geometry, earning the prestigious Ramanujan Prize in 2021.
20. Ashoke Sen (1956–present)
While known as a physicist, Ashoke Sen’s work in string theory has mathematical implications, particularly in topology.
