C V Raman

Sir Chandrasekhara Venkata Raman, commonly known as C V Raman, was an Indian physicist who made groundbreaking contributions to the field of light scattering, earning the Nobel Prize in Physics in 1930 for his discovery of what is now called the Raman Effect. Born on November 7, 1888, in Tiruchirapalli, Tamil Nadu, Raman demonstrated exceptional academic brilliance from childhood, completing his master's degree in physics at age 18. Despite initially working in the Indian Finance Service, his passion for scientific research led him to conduct experiments in his spare time at the Indian Association for the Cultivation of Science in Kolkata, where he made his famous discovery in 1928.

The Raman Effect describes how light changes its wavelength (and therefore energy and color) when passing through a transparent medium due to interactions with molecules, providing crucial information about molecular structure and chemical composition. This discovery revolutionized molecular spectroscopy and has applications in chemistry, physics, biology, and materials science—modern Raman spectroscopy is used in pharmaceutical quality control, gemstone identification, forensic analysis, and studying biological tissues. Raman was the first Asian to receive a Nobel Prize in any science category, bringing immense pride to India and inspiring generations of scientists. He founded the Indian Academy of Sciences and the Raman Research Institute in Bangalore, contributing significantly to building India's scientific infrastructure. National Science Day is celebrated on February 28th each year in India, commemorating the date of Raman's discovery. His legacy extends beyond his scientific contributions to demonstrating that world-class scientific research could be conducted in India despite limited resources, inspiring the development of indigenous scientific traditions and institutions.
