National Science Day

In 1986, India's National Council for Science and Technology Communication (NCSTC) asked the Government of India to designate February 28th as National Science Day. First held in 1987, National Science Day marks the discovery of the Raman effect, also known as Raman scattering, which is a scattering of photons or a "change in the wavelength of light that occurs when a light beam is deflected by molecules." Sir Chandrasekhara Venkata (C.V.) Raman, an Indian physicist who worked with light scattering, discovered the effect on February 28, 1928. Raman was awarded the Nobel Prize in Physics in 1930 for this work.

National Science Day aims to inform people of the importance of science in their daily lives. It is celebrated all over India, including in schools at all grade levels, and at other academic, research, scientific, medical, and technical institutions. It is marked with public speeches, lectures, science films, science exhibitions, television and radio events, debates, quiz competitions, and more. The National Science Popularization Awards, a part of the day, recognize "outstanding efforts in the area of science and communication." Each year there is a different theme for the day.
