In the ever-evolving realm of scientific exploration, certain discoveries stand out as monumental milestones, illuminating the path for future generations of researchers. Among these luminaries is Sir Chandrasekhara Venkata Raman, whose groundbreaking work revolutionized our understanding of light and matter.

Born on November 7, 1888, in Tiruchirappalli, Tamil Nadu, CV Raman emerged from an academic lineage. Despite health constraints, Raman's academic brilliance propelled him to graduate from Presidency College in Madras at just 16, earning a physics gold medal.

Raman's insatiable curiosity led him to explore the science behind musical instruments, publishing prolifically even while working as an assistant accountant general in Calcutta. His seminal visit to London in 1921 marked a turning point, where he garnered acclaim for his contributions to acoustics.

However, it was during his voyage back to India aboard the SS Narkunda that Raman's profound inquiry into the colors of the sky and sea ignited. In the interplay of light and atmosphere, blue light scatters more in the sky, making it look blue to us. Lord Rayleigh proposed that the sea looks blue because it reflects the color of the sky. This was widely accepted, but Dr. CV Raman thought differently. He believed that water molecules might be scattering the light to make the sea blue. However, he needed to prove his idea with experiments to be sure.

Raman embarked on a journey of experimentation that would ultimately culminate in the discovery of the Raman Effect—a phenomenon that revolutionized our understanding of molecular interactions with light.

The Raman Effect, elucidating how light interacts with molecules in any form, solid, liquid, or gas, revolutionized physics, chemistry, and bioscience. Raman's discovery not only garnered him the Nobel Prize in Physics in 1930 but also established India's scientific eminence on the global stage. Since the Raman effect was found on February 28, this day has been celebrated as the National Science Day.

Beyond its foundational impact, the Raman Effect continues to shape modern scientific endeavors. From identifying chemicals in laboratories to probing the atmospheres of distant celestial bodies, Raman's legacy endures as a beacon of scientific inquiry and national pride.

CV Raman's pioneering spirit extended beyond his scientific achievements. Instrumental in founding institutions like the Indian Institute of Science (IISc), Bangalore, and the Raman Research Institute, he nurtured a culture of scientific excellence that continues to inspire generations.

On National Science Day, as we honor the pioneering spirit of CV Raman, who dared to challenge the boundaries of human understanding. As we look to the future, let us draw inspiration from Raman's remarkable journey and continue to nurture a culture of curiosity, discovery, and collaboration. For in the realm of science, every day offers new opportunities to unlock the mysteries of the universe and shape a brighter, more enlightened tomorrow.
