Every year, India celebrates National Science Day on February 28 to mark the discovery of the Raman Effect and reinforce the importance of science in our daily lives.
The news: On this day, in 1928, Indian Physicist Chandrasekhara Venkata Raman discovered the “Raman Effect”, for which he won the 1930 Nobel Prize in Physics.
- Prime Minister Narendra Modi today greeted the nation on the occasion of National Science Day and called for reaffirming commitment towards leveraging the power of science for human progress.
- “National Science Day greetings to all scientists and science enthusiasts. Let us reaffirm our commitment towards fulfilling our collective scientific responsibility and leveraging the power of science for human progress,” the Prime Minister tweeted.
- Before the discovery of the Raman Effect the scientific world believed that the ocean simply reflected the blue sky. In the year1921, while returning from London on a steamship, Sir CV Raman observed the ocean and questioned the hypothesis.
- Driven by this he began his research in the Molecular Diffraction of Light that eventually led him to discover the Raman Effect in February 1928, along with his fellow scientist KS Krishnan.
- Today, the Raman Effect is used widely in our daily lives.
Theme of National Science Day 2022
- The theme for National Science Day 2022 is, ‘Integrated Approach in Science and Technology for Sustainable Future’.
- India has made advancement in terms of technology and space missions. Recently The Indian Space Research Organisation (ISRO) on February 14 launched India’s Polar Satellite Launch Vehicle PSLV-C52 along with two smaller co-passenger satellites into an intended sun synchronous polar orbit of 529 km altitude at 06:17 hours IST from Satish Dhawan Space Centre, SHAR, Sriharikota.
- This was the 80th launch vehicle mission from SDSC SHAR, Sriharikota; 54th flight of PSLV; and the 23rd flight of PSLV in XL configuration (6 strap-on motors).
