Distinguished guests and my dear friends, today I feel honored to stand before you and speak on the occasion of National Science Day 2023.
Every year, February 28 is celebrated as the National Science Day to commemorate the discovery of ‘Raman Effect’ by the genius Indian scientist, Sir C.V. Raman. Since 1986, the year of adoption of February 28 as the National Science Day, we have witnessed major scientific achievements by Indian and Indian-origin scientists. But do you really know what Sir Chandrasekhara Venkata Raman has achieved in his life?
Coming from a small family in Southern India, Chandrasekhara Venkata Raman has brought great laurels to India. He was born in Tiruchirappalli, Tamil Nadu on November 7, 1888. His father was a lecturer in Mathematics and Physics and from there he developed an interest in science.
He studied at St Aloysius Anglo-Indian High School, Visakhapatnam, and Presidency College, Madras. In 1904, he obtained a BSC degree from the University of Madras, where he stood first and won the gold medal in Physics. In 1907, he completed an MSc degree at the University of Madras with the highest distinction.
From 1907 to 1933, he worked in Kolkata at the Indian Association for the Cultivation of Science, doing research on various topics in Physics.
On February 28, 1928, Raman led an experiment with Indian physicist KS Krishnan, on the scattering of light, when he discovered what now is called the Raman effect. Raman Effect explains the effect on the scattering of light when passing through different materials.
After his retirement, Raman established the Raman Research Institute in Bangalore. Raman passed away on November 21, 1970.
Sir C.V. Raman is credited for the growth of science in India. He was awarded the prestigious Nobel Prize in 1930 for the discovery of ‘The Raman Effect’.
