India celebrates National Science Day on February 28 every year to mark the discovery of Raman Effect by Sir C V Raman. Sir Raman discovered the Raman Effect on Feb 28, 1928.
Wikipedia says Raman scattering or the Raman effect is the inelastic scattering of photons by matter, meaning that there is an exchange of energy and a change in the light’s direction. Typically this involves vibrational energy being gained by a molecule as incident photons from a visible laser are shifted to lower energy.
The theme of the National Science Day for the year 2018 was “Science and Technology for a sustainable future.” This year, the day was celebrated under the “Women in Science.”
National Science Day – History
The National Science Day was designated in the year 1986 and was celebrated for the first time in the year 1987.
Raman Effect Story
In the year 1921, on a boat trip back from England Indian physicist C.V. Raman, finding the answer to the question of why the sea is blue, started a research that led to the discovery of Raman Effect in February 1928.
- For this discovery C.V. Raman was also awarded Nobel Prize in 1930.
- The National Council for Science &Technology asked the Government of India to celebrate Feb 28 as the National Science Day.
- The National Council for Science &Technology works under the Department of Science & Technology, and is majorly involved in celebration of the Science Day.
