Top 10 Greatest Indian Scientists and their Inventions

Invention – when we first heard about this word the very utmost thing strike in our mind is a method, an innovative process or composition in different fields like physics, medicine, mathematics, chemistry, and biology. Invention is basically the process of creating something that has never been created before (whether for self-knowledge or for the benefit of the society). With the expertise in one or more areas of science an individual who uses a scientific method by conducting experiments, defines as a scientist. Scientists are our pride whether we say it for our nation or in the world of any area, scientists are honored and recognize till date through our studies for their great research works and inventions. 

There are more than 100 renowned scientists from India but below we have listed top 10 greatest scientists of our nation, who devoted their lives in researches and inventions and made our India a proud nation. Whether it’s C.V Raman or Salim Ali, these scientists have proved, established themselves and are count amongst the GREATEST SCIENTISTS OF INDIA.

2.) Salim Ali

(12th November 1896 – 20th June 1987) – Know as “Birdman of India”, was a great scientist of birds although we can say an ornithologist and naturalist.

Later Millard kindled in his desire to learn about birds and the young Salim Ali ventured into ornithology.

  • He was the renowned ornithologist despite having any formal training in the subject. The popular Salim Ali was among the first Indians to conduct systematic bird surveys across India. In 1947 he became a key figure at Bombay Natural History Society where he was actively involved in the creation of Bharatpur bird sanctuary. He also honored of his life’s work which includes Padma Bhushan and Padam Vibhushan.

S. Ramanujan

3.)Srinivasa Ramanujan

(22nd December 1887- 26th April 1920) We saw a lot of scientists, in them the greatest Mathematician Srinivasa Ramanujan got fame at the age of twenty-six. He was born in Erode town in Tamil Nadu on 22nd December 1887. The surprising fact we get to know about his life that even his college education was not completed due to his illness. He was keen on mathematics at that level where he started learning on his own, with the theory of learning he found the new formulas for solving out mathematical problems and also wrote articles. One of the articles when saw by the professor hardy a scientist of Cambridge University he was impressed and got an invitation towards England.

He was also considered as the master of the theory of numbers. In 1914 the formula for p (n), the number of partitions of ‘n’ was his outstanding contribution. And also known for his one of the valuable contribution which he developed while working in Trinity College the ‘Number Theory’ and also elected a fellow of Trinity College on 18th October 1917.He passed away on 26th April 1920.

From this invention early in the 20th century he got a count the greatest scientist of India. He won 1930 Nobel Prize in physics for the “Raman Effect and become the first Indian to win Nobel Prize in sciences, and in 1954 he was also honored with Bharat Ratna.
