Contribution of Indian Scientists in Science and Technology


Indian scientists have played a major role in helping the world advance scientifically by making some of the revolutionary inventions in the fields of mathematics, physics, nuclear energy, space research as well as agriculture. And it is through Ramanujan theories in mathematics and the outlook Vikram Sarabhai had on space that India has taken a prominent position on the world scientific horizon. These pioneers transformed their industries in their lives even though they had few resources or recognition during their youth. They have stories of great dedication to knowledge and national development. His legacy motivates the new generation of Indian scientists even now.

Conclusion for RPSC
India has a well-documented history of scientific-minded thinkers, not only developing the global science, but also working towards national tasks and problems, food security, space exploration, etc. Their cross-disciplinary contributions, which ranged between Ramanujan glamorous theorems to the Kurien milk revolution, demonstrates how scientific innovation can change things in societies. These heroes still motivate India to become a world leader in the knowledge and technology sector in the 21st century.
