National Science Day (NSD) is celebrated on February 28th each year to commemorate the renowned Indian physicist CV Raman. He received the 1930 Nobel Prize in Physics for discovering the Raman effect, a phenomenon in spectroscopy.
India’s most revered scientist Chandrasekhara Venkata Raman aka CV Raman was born on November 7, 1888 in Tamil Nadu. His father, a math and physics lecturer, was a major influence in encouraging Raman to pursue the science course.
CV Raman was fascinated by light scattering from an early age, which later led him to discover the change in wavelength observed when a beam of light is deflected by molecules. This scattering phenomenon has been termed “Raman scattering” or “Raman effect”.

This year the 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 just 11 years old, Raman passed matriculation as he was exceptional in his studies. He also passed the Intermediate Level Examination and two years later, in 1902, entered the Presidency College.
– Raman then got his bachelor’s degree in 1904, where he earned a first place and a gold medal in physics. After his bachelor’s degree, he also completed his master’s degree.
– Although Raman landed a government job in the colonial government’s finance department, he resigned. He was then appointed the first Palit Professor of Physics at the University of Calcutta in 1917.
– While teaching, he also conducted research at the Indian Association for the Cultivation of Science (IACS). In 1928, while conducting experiments on 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 the first Indian Director of the Indian Institute of Science (IIS) for his hard work and contribution.
– When India gained independence in 1947, Raman was elected the country’s first national professor. In 1954 he was also awarded India’s highest civilian honor, Bharat Ratna. Raman died in 1970.
– Years later, on February 28, 1987, the country celebrated the first National Science Day.
