Top 10 Indian Mathematicians of Modern Times

Indian has a rich history of great mathematicians/astronomers in ancient times, the likes of which include Brahmagupta, Varahamihira, Aryabhata, Baudhayana, who penned great mathematical and astronomical marvels. In modern times, however, mathematics has become highly specialized and abstract. In the last century or two India has produced a number of world-renowned mathematicians. Here is a compilation of top 10 Indian mathematicians of modern times.

Shakuntala Devi-Top 10 Indian Mathematicians


Shakuntala Devi is a world renowned mathematical genius. She has been nicknamed ‘Human Computer” because of her innate ability to solve complex mathematical problems without using any kind of aid. Among her other feats, her two most outstanding feats fetched her a place in the 1995 Guinness Book of World Records. The first one was in January of 1977, at the Southern Methodist University in Dallas, Texas, when she extracted the 23rd root of a 201-digit number, at the fifty-second mark, with the correct answer being ’546372891′. She had beaten the then fastest computer, UNIVAC’s time of 62 seconds. Her second feat was in June of 1980 when she demonstrated the multiplication of two 13-digit numbers: ’7,686,369,774,870 x 2,465,099,745,779′, picked randomly by the Computer Department of Imperial College of London. She produced the correct answer of ’18,947,668,177,995,426,462,773,730′, in just 28 seconds.

  1. I like the helpful info you supply to your articles. I will bookmark your blog and check again here frequently. I’m fairly sure I will be told a lot of new stuff proper here! Good luck for the next!

  2. there should be also Aryabhatt

  3. I remembering reading about Shakuntala Devi in my school days. She is truly a genius. But Srinivasa Ramanujan is a gem that comes about once in a century.

  4. I have personally met C.S. Seshadri as he was my brother’s professor at chennai mathematical institute. Truly a mathematical genius.

  5. I read somewhere that Hanuman or some other God used to come in the dreams of Ramanujan to teach him some of this theories.

  6. i aggree with aryan

  7. good i found what i want. ;)

  8. Good i found it :) :)

  9. is it so very very important that you mention ‘brahmin’?

  10. Shakuntala Devi is not a mathematician but a human number cruncher. Huge difference between the two.

    SN Bose is again not a mathematician. You are also missing MS Narasimhan and Abyankar’s names both leading figures in last 50 years of Indian mathematics.
