National Science Day 2023: In India, National Science Day is observed on February 28 to commemorate the discovery of the Raman effect by physicist Sir CV Raman on the same day in 1928. In 1930, he was awarded the Nobel Prize in Physics for this discovery.

The Raman effect, also known as Raman scattering, is the change in wavelength that occurs when a light beam is deflected by molecules.

The National Council for Science and Technology Communication (NCSTC) requested that February 28 be designated as National Science Day in 1986, and the Centre agreed. The event is now celebrated in schools, colleges, universities, and other educational and research institutions throughout India to inspire and encourage children to pursue careers in science.

National Science Day 2023 : Role of CV Raman, what is Raman Effect?

The Raman Effect was named after Chandrasekhara Venkata Raman, also known as CV Raman, who made an important discovery in the field of spectroscopy. CV Raman received the prestigious Nobel Prize in Physics in 1930 for his work.


Every year, National Science Day revolves around a theme; this year, the National Council for Science and Technology Communication (NCSTC) of the Department of Science and Technology chose “Global Science for Global Wellbeing” as the official theme for National Science Day 2023. (DST).

In recent years, themes such as “Science and Technology for Sustainable Development,” “Science and Technology for Indigenous Development,” and “Women in Science” have been used.

Students presenting science projects and national and state science institutions presenting their most recent findings are among the activities planned to commemorate National Science Day. Public speeches, radio-TV talk shows, science movie exhibitions, science exhibitions, stargazing, live projects, debates, quiz competitions, lectures, and a variety of other activities are also included.

CV Raman finished his master’s degree at the age of 19 and had established himself as a leading scientist in both India and the West. He made his first trip to England in the same year, 1921. On the way back, Raman noticed the Mediterranean Sea’s stark blue colour and wondered why it was blue rather than green. He hypothesised that the blue colour of the sea was caused by light being scattered by water molecules, and this hypothesis led him to further investigate light scattering.
