Every year on February 28th, India observes National Science Day to commemorate the discovery of the Raman Effect by renowned physicist Sir Chandrasekhara Venkata Raman, better known as CV Raman.
This day commemorates his groundbreaking contributions to science and technology, which have left a legacy that inspires generations around the world.
C.V. Raman, born on November 7, 1888, in Tiruchirappalli, Tamil Nadu, had a strong interest in science and education from an early age. His path to scientific excellence began with a bachelor’s degree in physics from Presidency College in Chennai, followed by a master’s degree from the University of Calcutta.
He then pursued doctoral research at the University of Cambridge, where his exceptional intellect and curiosity propelled him to extraordinary discoveries.
Raman’s most significant breakthrough occurred while he was a professor at the Indian Association for the Cultivation of Science (IACS), in Kolkata. In 1928, while conducting experiments on light scattering, he discovered an unexpected phenomenon that would change the course of physics. The Raman Effect demonstrated the inelastic scattering of photons by molecules, revealing important information about molecular structure and dynamics.
C.V. Raman became the first Indian to receive the Nobel Prize in Physics in 1930 after discovering the Raman Effect. His pioneering work not only improved our understanding of light-matter interactions, but also paved the way for numerous scientific and technological advances in fields such as spectroscopy, materials science, and telecommunications.
Other notable contributions include his work on musical instrument acoustics, in which he investigated the physics behind the sounds produced by various instruments. Raman also made significant contributions to the field of crystal physics, elucidating how light behaves when passing through transparent materials like crystals and gemstones.
Beyond his scientific achievements, C.V. Raman was a visionary leader who helped shape India’s scientific landscape. He advocated for the establishment of research institutes and laboratories to promote scientific inquiry and innovation in the country.
His efforts resulted in the establishment of the Indian Academy of Sciences and the Raman Research Institute, both of which continue to honor his legacy by encouraging excellence in scientific research and education.
Furthermore, C.V. Raman was deeply committed to science outreach and education, recognising the importance of nurturing young minds and instilling a scientific mindset in the masses. He believed in the democratisation of knowledge and worked hard to make science accessible to all segments of society, inspiring countless people to pursue careers in science and engineering.
As we commemorate National Science Day, we must reflect on C.V. Raman’s enduring legacy and invaluable contributions to the field of science. His insatiable curiosity, relentless pursuit of knowledge, and unwavering dedication inspire scientists, researchers, and students alike.
Furthermore, C.V. Raman’s legacy highlights the importance of investing in scientific research and innovation as drivers of socioeconomic development. By remembering him and celebrating his accomplishments, we reaffirm our commitment to fostering a culture of scientific inquiry, creativity, and excellence in India and beyond.
National Science Day honors C.V. Raman’s remarkable legacy, whose brilliance and passion continue to illuminate the path of scientific discovery. As we honor this visionary Nobel Laureate, let us renew our commitment to pushing the boundaries of science and creating a better future for future generations.
