National Science Day 2022

On 28 February, every year National Science Day is celebrated to recognize the contributions of scientists towards the nation’s development.


  • On 28 February 1928, an important discovery in the field of spectroscopy was made by renowned Indian Physicist Chandrasekhara Venkata Raman. Later, this discovery was named after him i.e. the Raman Effect.
  • In 1930, CV Raman received the Nobel Prize in Physics for his work.

The theme of National Science Day 2022

‘Integrated Approach in Science and Technology for Sustainable Future’ is the theme for this year’s National Science Day.

History of this day

In 1986, National Council for Science and Technology Communication asked the Indian government to declare February 28 as the National Science Day. The day was named National Science Day after the government accepted the proposal. On February 28, 1987, the first National Science Day was observed in India.

Significance of this day

The objective of National Science Day is to increase awareness about the importance of science. Radio, public speeches, science movies, television, science exhibitions on various concepts and themes, quiz competitions, debates, science model exhibitions, and lectures are some of the ways that educational institutions celebrate National Science Day.

About CV Raman

CV Raman was an Indian physicist and is known for his work in light scattering under the fields of physics. He and his student K. S. Krishnan, using a spectrograph developed by Raman, discovered that when light passes through a transparent medium, the frequency, and wavelength of the deflected light change. They named this phenomenon “modified scattering” and was later termed the Raman scattering or Raman effect. In 1930, CV Raman received the Nobel Prize in Physics for this discovery and was Asia’s first person to receive a Nobel Prize in science.
