On 7 November 1888, an extraordinary mind was born in Thiruvanaikoil, near Tiruchirappalli in present-day Tamil Nadu. His name was Chandrasekhara Venkata Raman, popularly known as C. V. Raman. He would go on to become one of India’s greatest scientists, win the Nobel Prize in Physics and bring international recognition to Indian scientific research. But beyond his discoveries and awards, Raman’s life offers a much deeper lesson: the pursuit of truth requires curiosity, courage, independent thinking and the willingness to reject what is false, even when doing so challenges established beliefs. His birth anniversary is an opportunity to remember not just a Nobel laureate, but an Indian who believed that science could create a fellowship among human beings that divisions of religion and creed often fail to achieve.
Raman was born into a family where education and intellectual curiosity were valued. His father taught mathematics and physics, and young Raman developed an interest in scientific subjects at an early age. He was an exceptionally bright student, completing his undergraduate studies at Presidency College, Madras, in 1904 and his master’s degree in 1907. At a time when opportunities for pursuing scientific research in India were limited under British rule, he initially entered government service in the Finance Department in Calcutta. However, a secure government position could not take away his passion for science. Even while working as an Assistant Accountant General, he continued conducting scientific research whenever he could find the time. His dedication eventually led him to leave government service and accept a professorship in physics at the University of Calcutta in 1917. This decision marked the beginning of one of the most remarkable chapters in Indian scientific history.
An interesting episode that reveals Raman’s curiosity took place during a voyage from England to India in 1921. While travelling by ship, he began wondering why the sea appeared blue. Rather than simply accepting the commonly offered explanation that the sea reflected the blue colour of the sky, he wanted to investigate the phenomenon himself. Carrying simple optical instruments, including a pocket spectroscope and a prism, he examined the light coming from the water. His observations encouraged him to investigate the scattering of light further. This curiosity eventually contributed to a line of research that culminated in one of the most important discoveries in modern physics. It demonstrates something fundamental about scientific thinking: a question that others might overlook can become the beginning of a discovery when someone has the courage to investigate it rather than accept an explanation without examination.
On 28 February 1928, Raman and his research collaborators, including K. S. Krishnan, observed a phenomenon in which a small portion of light scattered by molecules emerged with a different wavelength from the incoming light. This became known as the Raman Effect. In simple terms, light interacting with molecules can exchange energy with them, resulting in a change in the wavelength of some scattered light. This discovery opened new possibilities for understanding the molecular structure of substances and laid the foundation for Raman spectroscopy, which is now used in chemistry, physics, medicine, pharmaceuticals and materials research. What began with curiosity about light and the natural world became a discovery of international scientific importance.
The recognition that followed was extraordinary. In 1929, the British Government conferred a knighthood upon Raman, giving him the title ‘Sir’. This is why he came to be known as Sir C. V. Raman. The following year, in 1930, he received the Nobel Prize in Physics for his work on the scattering of light, becoming the first Indian Nobel laureate in science. It was a remarkable achievement for an Indian scientist working in a country that was still under British colonial rule. His recognition demonstrated that scientific excellence was not the property of any particular nation or civilisation. An Indian researcher, working with his own intellectual determination and scientific methods, could make a discovery that the entire world would recognise. In 1954, independent India honoured him with the Bharat Ratna, the country’s highest civilian award. He also helped establish important scientific institutions, including the Indian Academy of Sciences and the Raman Research Institute in Bengaluru, ensuring that scientific inquiry would continue to grow in India beyond his own lifetime.
Yet one of the most meaningful aspects of Raman’s thinking is found not in a laboratory, a medal or a scientific paper, but in a conversation involving Mahatma Gandhi and a Swiss scientist, Dr. Rahm. During their meeting, a discussion arose about conflict in the world, competing religious beliefs and atheism. Raman offered a perspective that deserves particular attention even today. He argued that religions could not unite humanity in the way science could. He expressed the view that science offered the best opportunity for complete fellowship and declared that all men of science were brothers. Gandhi responded humorously by asking whether those who were not men of science were therefore not brothers. Raman replied that all could become men of science.
This exchange reveals something important about his understanding of science. He was not suggesting that only scientists deserved brotherhood or that ordinary people should be excluded from scientific thinking. Rather, he believed that the scientific attitude was something every human being could develop. It did not require a particular religion, race, nationality, caste or social background. Anyone willing to observe, question, investigate and accept evidence could participate in the search for truth. Scientific inquiry does not ask which religion a person follows before examining an observation. It does not change the laws of nature according to nationality or social identity. The same evidence and principles can be examined by people across the world. In this sense, science offers a common ground where intellectual honesty can become more important than inherited divisions.
Raman expressed this philosophy beautifully in his words: “Science is nothing but a research for truth — truth not only in the physical world, but in the world of logic, psychology, behaviour, and so on.” He went further, explaining that the virtue of a truly scientific frame of mind lies in the readiness to reject what is false and untrue. He believed there was no virtue in sticking to untruth. These words are particularly relevant in a world where people sometimes defend an opinion simply because it belongs to their group, community, religion or political side. A scientific mind must be prepared to question even its own assumptions. It must have the courage to accept a fact even when that fact is uncomfortable. Truth should not become different depending on who speaks it or who benefits from it.
There is also a profound connection between this approach and spirituality. Science and spirituality are often presented as opposing paths, but the deeper purpose of both can involve the search for understanding, the examination of existence and a sense of wonder about the universe. Science investigates the natural world through observation, experimentation and evidence, while spirituality explores questions of meaning, consciousness and our place in existence. Raman’s own remarks about the universe and the discoveries of astronomy and physics revealing more about the mysteries of existence show his sense of wonder. Although he should not be quoted as declaring science and spirituality identical, his outlook allows us to appreciate how scientific curiosity can deepen our sense of awe towards the universe. When the pursuit of knowledge is accompanied by humility, honesty and openness, it can become a deeply meaningful human journey.
India also remembers Raman every year on 28 February as National Science Day, commemorating the discovery of the Raman Effect on that date in 1928. The Government of India designated the day in 1986, and the first National Science Day was celebrated in 1987. Its purpose is to promote scientific awareness and encourage people, especially young minds, to understand the importance of science in everyday life. Raman’s Nobel Prize in 1930 and Bharat Ratna in 1954 remain milestones in India’s scientific history, but perhaps his greatest contribution was demonstrating what an Indian mind could achieve through curiosity, discipline and independent thought.
For readers interested in exploring Raman’s thoughts beyond this article, we recommend reading C. V. Raman: A Memoir by Dr. A. Jayaraman, published by the Indian Academy of Sciences.

On his birth anniversary, let us remember C. V. Raman not merely as the scientist whose name became attached to a remarkable discovery, but as a thinker who recognised the importance of truth beyond the boundaries that divide humanity. His message remains relevant: do not accept something merely because it is popular, do not defend falsehood because it is convenient, and never stop questioning in the pursuit of knowledge. A truly scientific mind is not simply one that knows many facts; it is one that remains willing to discover, reconsider and correct itself. Perhaps that is one of the most valuable lessons we can take from his life: the search for truth belongs to everyone, and when humanity learns to pursue it together, science can become a powerful bridge between people.
