Top 10 Indian Scientist Who Changed The World

Indians have contributed immensely in the field of science and technology. This article takes us down the memory lane of some of the brilliant minds in India.

Looking around you will find Indians reaching heights in every area. With the ease of accessibility of information, improvement in technology and the growth of quality institutions, Indians are able to use their capability and mind to its best. But even during British India, Indians were responsible for contributing and developing in the field of science and getting honors and awards for the same. Amongst the many here is a list of 10 Indian scientists who succeeded in changing the world.

Raman has conducted a lot of research and experiment and the most known discovery was his “Raman effect”.
He was awarded Noble Prize in 1930 for “work on the scattering of light”.
Raman showed that the energy of photons scattered inelastically serves as a ‘fingerprint’ for the substance the light is scattered from.
Apart from Noble prize he also received the prestigious Bharat Ratna Award for the Raman Effect.
He became the director of the Indian Institute of Science, Bangalore, India’s first National Professor and founded the Raman Research Institute, Bangalore.

He was known for his work in quantum mechanics and one of the two classes of particles in quantum mechanics was named “Bosons” after him.
He also worked on the Planck’s blackbody radiation law.
Later he also worked with Albert Einstein and they formed some ideas which were known as Bose-Einstein Statistics.
He was given the title of Padma Vibhushan in 1954.
Further Rabindranath Tagore dedicated his only book on science, ‘Visva–Parichay’, to Bose.
