C. V. Raman: A Legacy of Discovery, Innovation, and Inspiration

November 10 – World Science Day for Peace and Development

Inspirational Desk, Delhi MagazineNovember holds a special place in the history of science, particularly for India. November 7 marks the birth anniversary of Sir Chandrasekhara Venkata Raman, one of India’s most distinguished scientists. His name was announced as the recipient of the 1930 Nobel Prize in Physics, and he passed away on November 21, 1970. November 10 is celebrated every year as World Science Day for Peace and Development. These important dates provide an excellent opportunity to remember the extraordinary life, scientific achievements and lasting legacy of C. V. Raman.

Early Life and Educational Achievements of C. V. Raman

C. V. Raman was born on November 7, 1888, in Tiruchirappalli, Tamil Nadu. His father was a lecturer in mathematics and physics, which provided him with an academic environment from an early age. Raman demonstrated exceptional intellectual ability during his school and college years.

He entered Presidency College, Madras, and secured first position in his B.A. examination in 1904, winning a gold medal in Physics. He completed his master’s degree in 1907 with outstanding academic distinctions. His interest in scientific research was evident even during his student days, when he began investigating subjects related to optics and acoustics.

At that time, opportunities for pursuing a career in scientific research were limited in India. Consequently, Raman joined the Indian Finance Department in 1907. However, his government responsibilities could not diminish his passion for science. While working in Calcutta, he continued conducting experiments at the Indian Association for the Cultivation of Science (IACS). His dedication demonstrates how determination and curiosity can help individuals overcome limitations.

Scientific Career and Research on Light and Sound

In 1917, Raman accepted the position of Professor of Physics at the University of Calcutta. This appointment marked a significant turning point in his scientific career. He devoted himself to research in several branches of physics, particularly optics and acoustics.

One of his interesting research areas was the science behind musical sounds. He investigated the vibrations and acoustic properties of traditional Indian musical instruments, including the veena and mridangam, as well as instruments such as the violin. His research helped explain the scientific principles responsible for the distinctive sounds produced by musical instruments.

Raman’s work demonstrated that science is not restricted to laboratories, complicated equipment or theoretical discussions. Even familiar objects and everyday experiences can become subjects of important scientific investigations when observed with curiosity and an analytical mind.

Discovery of the Raman Effect: A Landmark in Physics

One of the most remarkable achievements in the history of Indian science was Raman’s discovery of the phenomenon now known as the Raman Effect.

During his voyage to Europe in 1921, Raman became fascinated by the blue colour of the Mediterranean Sea. He questioned the commonly accepted explanations for the appearance of the sea and began investigating the scattering of light. This curiosity eventually contributed to a series of experiments that led to his historic discovery.

On February 28, 1928, Raman and his research collaborators, particularly K. S. Krishnan, observed an important phenomenon involving the scattering of light. They found that a small portion of light scattered by a transparent substance changes its wavelength or frequency. The change depends on the molecular properties of the substance through which the light passes.

This discovery provided scientists with a new method of understanding the interaction between light and matter. The phenomenon became internationally known as the Raman Effect. Raman and K. S. Krishnan published their research in the journal Nature on March 31, 1928.

The discovery became a milestone in spectroscopy and opened new possibilities for studying the molecular structure and properties of different materials.

C. V. Raman and the Nobel Prize in Physics, 1930

Raman’s groundbreaking research received international recognition in 1930 when he was awarded the Nobel Prize in Physics for his work on the scattering of light and the discovery of the Raman Effect. He became the first Asian scientist to receive the Nobel Prize in a scientific discipline.

The Nobel Prize award ceremony took place on December 10, 1930. His achievement was particularly significant because he had conducted much of his pioneering research in India, despite the limited scientific facilities available at that time.

One of the reasons I admire C. V. Raman so deeply is that he demonstrated how world-class scientific discoveries could emerge from India. His success challenged the belief that extraordinary scientific achievements were possible only in countries with advanced research facilities. His life continues to inspire Indian students, researchers and educators to pursue scientific excellence with confidence.

Contribution to Indian Scientific Institutions

Apart from his individual scientific achievements, Raman made remarkable contributions to strengthening the scientific research environment in India.

On March 31, 1933, he became the first Indian Director of the Indian Institute of Science (IISc), Bengaluru. He served as Director until July 19, 1937, and continued his association with the institution as a Professor of Physics until 1948.

Raman also played an important role in establishing the Indian Academy of Sciences in 1934. The Academy was registered on April 24, 1934, and formally inaugurated on July 31 of the same year. Its establishment reflected his commitment to promoting scientific research, encouraging intellectual discussions and creating opportunities for young researchers.

In 1948, he established the Raman Research Institute in Bengaluru. After leaving the Indian Institute of Science, he devoted himself to research at this institution. The institute continues to carry forward his scientific legacy through research in several areas of science.

Today, international research partnerships are creating new opportunities for Indian scientists, including the India-EU Horizon Europe research cooperation initiative.

His contribution to establishing scientific institutions is as significant as his own discoveries. He understood that the progress of science depends not only on individual brilliance but also on institutions that encourage research, innovation and the development of future scientists.

Raman’s Curiosity and the Importance of Scientific Observation

Another quality of C. V. Raman that I greatly admire is his extraordinary spirit of inquiry. He possessed the ability to look at ordinary things from an unusual scientific perspective.

The blue colour of the sea, which many people simply admire as a beautiful natural sight, inspired him to investigate the scientific principles behind it. His observations during his 1921 voyage to Europe became an important source of inspiration for his research on light scattering.

Encouraging scientific curiosity among young students is equally important, as demonstrated by the Vikram Sarabhai Space Exhibition at Pathania Public School, which introduced students to space science and India’s scientific achievements.

As a teacher, I believe that this is one of the most valuable lessons we can learn from his life. Education should not merely provide information or encourage students to memorise facts. It should develop their ability to observe, analyse, question and discover.

A good education system must encourage students to think independently and develop a scientific temperament. Raman’s life demonstrates that a simple question, when pursued with dedication and systematic investigation, can lead to a discovery of international importance.

Kamala Sohonie and the Importance of Equal Opportunities in Science

While remembering Raman’s contributions, it is also important to examine the historical challenges faced by women who wanted to pursue scientific education and research during his time.

The experience of Kamala Sohonie, a pioneering Indian biochemist, is particularly significant. Historical accounts indicate that when she sought admission to the Indian Institute of Science in the 1930s, she initially faced resistance because she was a woman. Raman, who was then Director of the institution, was associated with the opposition to women’s admission. She eventually secured admission under certain conditions.

Sohonie went on to make important contributions to biochemistry and became a pioneering woman scientist in India. Her experience reminds us that scientific progress must be accompanied by equal educational and research opportunities.

While appreciating the achievements of great scientists, it is equally important to understand the limitations and social attitudes of their historical period. The scientific community today must ensure that talent, dedication and intellectual ability receive equal recognition, irrespective of gender.

Bharat Ratna and Other Honours

In recognition of his outstanding contributions to science, C. V. Raman received several prestigious awards and honours during his lifetime.

In 1954, he was awarded the Bharat Ratna, India’s highest civilian honour. He was among the first three recipients of this prestigious award in the year it was instituted. The other recipients in 1954 were Chakravarti Rajagopalachari and Sarvepalli Radhakrishnan.

Earlier, he had been elected a Fellow of the Royal Society in 1924 and was knighted in 1929. His Nobel Prize, Bharat Ratna and other international recognitions reflected the importance of his contributions to physics and the development of scientific research.

C. V. Raman’s Death and His Lasting Scientific Legacy

C. V. Raman passed away on November 21, 1970. However, his discoveries, scientific institutions and intellectual contributions continue to inspire researchers and students across the world.

In India, February 28 is observed every year as National Science Day to commemorate the discovery of the Raman Effect in 1928. The occasion highlights the importance of scientific research, innovation and the contribution of science to national development.

The Raman Effect also continues to have practical applications in modern scientific research. Raman spectroscopy is widely used to study the molecular composition and properties of materials. Its applications extend to chemistry, physics, material science, pharmaceuticals, forensic investigations and several other research fields.

The continuing relevance of this discovery demonstrates how an important scientific observation can create opportunities for research and technological development long after the lifetime of the scientist who made it.
