Sir C.V Raman’s 132nd Birth Anniversary: A Leader Of India’s Early Scientific Movement
Remembering the eminent Physicist, Nobel Laureate & Bharat Ratna Sir C.V Raman on his 132nd Birth Anniversary.
An enthusiast of physics from a very young age, Sir Raman completed his Master’s in Physics from Presidency College of Madras in 1907, at the age of 19, with the highest distinctions. It was in the college itself where his potential and self-will were recognized and he was given unlimited access to the laboratories.
“The Raman Effect, whose explanation agrees so well with quantum theory, will undoubtedly become a vital source in growing our knowledge of the states of atoms or molecules in transitions, between which their characteristic spectra are emitted.” – Niels Bohr
The observations were first published in 1928 titled ‘A New Radiation’ in the Indian Journal of Physics (Volume 2, 1928). What came to be known as The Raman Effect is a colour change accompanied by the polarization of light, never before was this ever phenomenon recorded.
The discovery earned CV Raman the 1930 Nobel prize in physics, the first in Asia.
In 1933, Sir C.V Raman became the first Indian director of the Indian Institute of Science, Bangalore. He was a patron of scientific research in India and has contributed towards the building up of nearly every Indian Research Institution in his time. Sir Raman has been honored with a number of honorary doctorates and memberships of Scientific Societies.
- Experimental and theoretical studies on the differentiation of light by acoustic waves of Ultrasonic and Hypersonic frequencies.
- Effects produced by X-rays on infrared vibrations in crystals exposed to ordinary light [fundamental problems of crystal dynamics.]
- Structure and properties of diamonds.
- The optical behavior of numerous iridescent substances (labradorite, pearly feldspar, agate, opal, and pearls.)
- Optics of Colloids.
- Electrical and Magnetic anisotropy.
- Physiology of Human vision.
He was honored with Bharat Ratna (India’s Highest Civilian Award) in 1954.
“I strongly believe that fundamental science cannot be driven by instructional, industrial and government or military pressures. This was the reason why I decided, as far as possible, not to accept money from the government.”
– C. V. RAMAN
