National Science Day is celebrated in India on February 28th each year to commemorate the discovery of the Raman Effect by Sir C.V. Raman. This day is dedicated to the promotion of scientific activities, awareness, and understanding of the importance of science and technology in the country.
On February 28, 1928, Sir Chandrasekhara Venkata Raman announced the discovery of the Raman Effect, for which he was awarded the Nobel Prize in Physics in 1930. The Raman Effect refers to the inelastic scattering of light by molecules, which provides valuable information about the vibrational and rotational modes of molecules. This discovery was a significant achievement in the field of physics and brought international recognition to Indian science.
National Science Day is an occasion to celebrate scientific accomplishments and to encourage scientific thinking among the youth. Various scientific institutions, schools, and colleges organize events, seminars, workshops, and exhibitions to mark the day. The day also serves as a reminder of the importance of fostering a scientific temper in society and promoting scientific research and innovation. Each year, National Science Day is celebrated with a specific theme that highlights a particular aspect of science and its role in society.
