Many people know Chandrasekhara Venkata Raman (more popularly known as C.V. Raman) because he was the first Indian Nobel Laureate in science. Till date Raman remains the only Indian to receive a Nobel Prize in science. There are two Indian-born scientists viz., Har Gobind Khorana and Subrahmanyan Chandrasekhar (who became US citizens) got Nobel Prizes in science. Raman was also the first Asian to get Nobel Prize in science. Raman's celebrated discovery, the Raman Effect, experimentally demonstrated that the light-quanta and molecules do exchange energy which manifests itself as a change in the colour of the scattered light. However, this phenomenon was earlier predicted theoretically by Hendrik Anthony Kramers (1894-1952) and Werner Heisenberg (1901-76). It was the most convincing proof of quantum theory of light. This does not diminishes the importantce of Raman's discovery. As Albert Einstein (1879-1955) wrote : "C.V. Raman was the first to recognize and demons...
