India has a rich history of producing countless Great Indian Mathematicians and astronomers, since ancient times. Indians always contributed a vital role in the field of Mathematics to make a better world for human being.Whenever we will talk about the Great Indian Mathematicians, the list will always starts with Srinivasa Ramanujan because Ramanujan did it without having a training in Mathematics so its a power of God on him so here is the list of a few Great Indian Mathematicians –
1. Srinivasa Iyengar Ramanujan- Ramanujan gives more than 3900 results in the field of Mathematics and the all his claims have been proven correct. He lived during British rule between 22 Dec-1987 to 26 April-1920. Ramanujan Known for his ‘Ramanujan Constant’, ‘Mock Theta functions’, ‘Ramanujan Conjecture’, ‘Ramanujan Prime’, ‘Ramanujan’s Sum’, ‘Number theory’, ‘Infinite series’, ‘Continued fractions’ and many more results, mostly ‘identities’ and ‘equations’. The word Ramanujan means ‘Younger brother of God Rama’ and Srinivasa means ‘The place where the female energy of the God Lives’.
2. Aryabhata – Aryabhata (447 to 550 A.D.), one of world’s greatest mathematician and astronomer was born in Patliputra in Magadha (Now Patna in Bihar), India. Aryabhata becomes immortal after these contributions in mathematics – Discovery of place value system, Value of Pi (3.1416), invention of Trigonometry, Log tables, Formula for Arithmetic and Geometric Progressions, Heliocentric theory, Eclipses occurrence, Boolean logic, total length of the sidereal year as 365 days and many more.
3. C. R. Rao – Calyampudi Radhakrishna Rao born on 10 September 1920 in Karnataka, India and he was among the first few people in the world to hold a master’s degree in Statistics. Rao becomes a great Indian mathematician for his famous Estimation theory, Statistical interference and Linear models, Multivariate Analysis, combinatorial design, Orthogonal arrays, Biometry, statistical genetics, functional equations and many more.
4. D. R. Kaprekar – Dattathreya Ramchandra Kaprekar (1905-1986) was a school teacher in Nashik, Maharashtra. He described several classes of numbers like Kaprekar, Harshad, self numbers and discovered the kaprekar constant, named after him. Without any formal mathematical education and being a school teacher, Kaprekar became a great Indian Mathematician in recreational mathematics circles.
5. P. C. Mahalanobis – The Father of statistics and the founder of Indian Statistical Institute, Prasanta Chandra Mahalanobis (29 June 1893 – 28 June 1972) born in Calcutta, India. He is best known for his ‘Mahalanobis distance’ theory. He world for Indian government as a scientist and applied statistician.
6. Harish Chandra – An Indian American mathematician and physicist born (11 October-1923 to 16 October-1983) in Kanpur, Uttar Pradesh. He is known for his famous ‘Infinite dimensional group representation theory’, especially harmonic analysis on semisimple lie groups.
7. Satyendra Nath Bose – Bose was born (1 January 1894 to 4 February 1974) in Calcutta, India. He was best in quantum mechanics and also known for his collaboration with Albert Einstein and the theory of Bose-Einstein condensate.
8. Narendra Krishna Karmakar – Karmakar born in Gwalior, Madhya Pradesh, India and know for Karmakar’s Algorithm. Karmakar’s Algorithm solves linear programming problems in polynomial time.
9. Brahmagupta – Brahmagupta born in Bhinmal, Rajasthan, was a great Indian Mathematician and astronomer because he was the first one who invented ZERO. Countless invention by him made him immortal in the filed of Mathematics. The Concept of Negative numbers were given by him.
10. C. S. Seshadri – Seshadri born on 29 February 1932 in kanchipuram, Tamil Nadu. He is known for his outstanding contribution in Algebra geometry and invented Seshadri constant, Narasimhan-Seshadri constant and standard monomial theory.
There is countless list of Great Indian Mathematicians who have contributed a lot towards the field of mathematics and their great work will always continue to enlighten world. Without having a formal training, few of great Indian mathematicians shows that if you wants to get something with full devotion and dedication then nobody can stop you until and unless you will not give up.These mathematicians were not only a person, they were and always will be a great personality who did it for the whole world.
