National Science Day

National Science Day is celebrated annually on February 28.

National Science Day is celebrated to commemorate the discovery of Raman Effect by Nobel laureate, physicist CV Raman on this day in 1928.

Objective of NSD:

To bring awareness to people about the importance in our daily life and to encourage people by popularizing the Science and Technology. Every year, the day is celebrated with a particular theme.

The first National Science Day was celebrated in 1986. The National Council for Science & Technology urged the Government of India to designate February 28 as National Science Day. Since 1987, the event is now celebrated all over the country in schools, colleges, universities and other academic, scientific, technical, medical and research institutions.

The celebration also includes public speeches, radio, TV, science movies, science exhibitions, research demonstration, debates, and many more activities.

Chandrashekhara Venkata Raman was a physicist from Tamil Nadu. His work in the field of light scattering earned him Nobel Prize for Physics in 1930. This phenomenon was known as Raman effect. In 1954, he was honoured with India's highest civilian award, the Bharat Ratna. Awarded Noble prize in 1930.

He was the first Asian and first non-white to receive any Nobel Prize in the sciences.

In 1928 he found that when a transparent substance is illuminated by a beam of light of one frequency, a small portion of the light emerges at right angles to the original direction, and some of this light is of different frequencies than that of the incident light. These so-called Raman frequencies are the energies associated with transitions between different rotational and vibrational states in the scattering material.

The theme of the year 2021 is "Future of Science Technology and Innovation (STI): Impacts on Education, Skills and Work."
