Interesting facts about Nobel laureate CV Raman and why the day is important

The theme of the National Science Day this year is ‘Integrated Approach in S&T for a Sustainable Future’.

National Science Day (NSD) is celebrated on February 28 every year in memory of noted Indian physicist CV Raman. He won the Nobel Prize in Physics in 1930 for discovering the Raman effect, a phenomenon in spectroscopy.

India’s most respected scientist, Chandrasekhara Venkata Raman, also known as CV Raman, was born on November 7, 1888 in Tamil Nadu. His father, who was a teacher of mathematics and physics, had been a great influence on Raman to follow the scientific course.

From his early years, CV Raman was fascinated by the scattering of light, which led him to later discover the change in wavelength observed when a ray of light is deflected by molecules. This scattering phenomenon was called ‘Raman scattering’ or the ‘Raman effect’.


This year’s theme of the National Science Day is “Integrated Approach in S&T for a Sustainable Future”.

On the occasion of National Science Day 2022, here are some interesting facts about CV Raman:

– At the age of only 11, Raman passed the entrance exam because he was exceptional in his studies. He also passed the Intermediate exam and entered the Presidium College two years later in 1902.

– Raman then received his bachelor’s degree in 1904, where he obtained a first grade and a gold medal in physics. After his bachelor he also completed his master.

– Despite getting a government job in the finance department of the colonial government, Raman quit. He was then appointed as the first Palit Professor of Physics at the University of Calcutta in 1917.

– During his teaching period, he simultaneously conducted research at the Indian Association for the Cultivation of Science (IACS). In 1928, while experimenting with light scattering, he proudly discovered the ‘Raman effect’.

– A year later, Raman won the Knight Bachelor Award and became a Fellow of the Royal Society. In 1933, he was appointed as the first Indian Director of the Indian Institute of Science (IIS) for his hard work and contributions.

– When India gained independence in 1947, Raman was chosen as the country’s first national professor. He also received India’s highest civilian award, Bharat Ratna in 1954. Raman died in 1970.

– Years later, the country celebrated the first National Science Day on February 28, 1987.
