Dr CV Raman: The Celebrated Genius Summary

Dr. C.V. Raman, gone down in the annals of science (National as well as International) as celebrated genius rightly and deservingly so. He looked upon science as God and considered work as his religion. His unswerving dedication to the development of science and research in India (a county which did not figure anywhere on the map of science), is extremely laudable. He brought laurels not only to his own person but to India – an extremely backward country in science and this he did at a time when she (India) was panting under the colonial rule of the British.

Right from his early age, he displayed the signs of genius, and an undeniable fact evidenced by the fact that he passed his matriculation at the age of 11 with honors and graduated at 15-achievements almost unbelievable.

Hailing from extremely orthodox Brahman family of Tamil Nadu, he rose to the heights of occupying the Directorship of ‘The Institutes of Science and Technology’ at Bangalore— a post he held for 15 years till his retirement, needless to say, that he was the first Indian to occupy the post.

After having got his Masters in Physics and Literature and having qualified the competitive exams of Finance department– he started his career as assistant Account General in Calcutta – an extremely lucrative post that fetched him quite a handsome salary , but he did not feel contented as it pushed him away from his first and last love ‘science’.

It was his undying and never dwindling zeal and passion for science that bought him in contact with an institute named Indian ‘Association for Cultivation of Science’ at 210 street Calculate run by Amit Lal Sarkar. Such was his passion for science that he continued his research programme in the institute from six to nine in the morning and from five to ten in the evening, besides discharging his routine duties as Assistant Account General.

He was offered the Palit Chair of Physics AT Calcutta University by Dr. Mukherji and he accepted without sparing a moment’s thought — though the University paid him almost half the salary, he got from the government. It was as representative of Calcutta University that he had to make a voyage to Europe in 1921 to attend a science conference there and this voyage proved to be a turning point in his career as, having been inquisitive by nature since his birth. He was surprised by the deep blue coloration of Meditterian waters and his inquisitive mind ruled out the standing explanation that it must be due to the reflection of the blue sky. This triggered his exploring mind and ceaselessly for almost seven years to unravel the mystery and give the world his theory of Scattering.

The phenomenon of light while passing through different media, together with the Quantum theory of light which has gone under his name as ‘Raman Effect’. It was this discovery that won for him the much coveted and prestigious.

Nobel Prize. Thus he became the first Indian– nay Asian who rose to the status of Noble laureate. Raman had a very deep love for his country- India. This is evidenced by the fact that he suffered a nervous breakdown while receiving Nobel Prize from the hands the Swedish King Gustav and tears gushed down his cheeks when he realised that he was standing under the Union Jack (British Flag) and not the Indian tri-colour which meant that his poor country—India did not have a flag of her own. Besides, he never opted for a European hat and suit in place of a typical Madrasi dress.

It was in acknowledgment of his scientific genius that personalities like with great personality like Rutherford and Neil Buhr etc. established friendship with him.

C.V. Raman was so deeply obsessed by the passion of promoting science and research in India and setting up a research Institute of his own that he traversed the whole country, collecting money from every possible source.

This was necessitated by the unfortunate incident of his having lost the entire savings of his life in the ‘South Sea Babble’ catastrophe. He did not feel shy of it remarking that all great Indians like Shankara, Buddha, and Gandhi had been beggars. Finally, he did succeed in establishing the ‘Raman Institute’ on a piece of land (about 31 acres) donated by a local landlord who too had the similar desire to see India on the science map of the world.

Raman’s keen ear for music and it was this trait of his personality that brought him in touch with Lokasundri, a Vienna whom he finally wedded as a life partner. He confronted a lot of problems in his life, but never felt depressed and deterred. One of the major causes of these problems was his irritable temperament and too harsh a behavior.

He believed in simple living, close to Nature itself. His philosophy of life and concept patriotism were novelties and down to earth realistic. He believed in simple living and very high thinking. Patriotism for him meant the love of mother earth which could be exhibited by nurturing it, making it more and more productive without causing any damage to its texture. Simple things like a glass of plain water, a long walk in the woods, and a loaf of Ragi fascinated him more than anything else. He perceived Oneness in science and nature and never gave up serving them. He laid upon his countrymen to study science to be of some use to the country. He was a great and effective orator, educationist as well as a humanist. He preached that Indians needed to spend much of their time on the education of their children— spending money alone was not enough. To him, it was not just spending money that would transform the illiterate and scientifically backward India into the heaven of literacy. His speeches packed with wit and wisdom and spiced with humour inspired the youth all over the country and taught them not to lose heart and courage even in heavy odds– not to be deterred ever and never to say die.


1 How were the great men who Raman read about as a child reflected in the work he did later in life ?

He is both a savvy and voracious reader and anxiously pored over all the books in the collection of his father. Some of these are ‘ original writings of the exceptional scientists. He once said,“out of this welter of subjects and books, can I pick anything really mould my mental and spiritual outlook and determine my chosen path? Yes, I can and shall mention three books. These three were Edwin Arnold’s ‘Light of Asia’ which is the life story of Lord Gautama Buddha. Second one is titled ‘The Elements of Euclid’, is a treatise on Classical Geometry. ‘The Sensations of Tone’ is the last one and was authored by German scientist Helmholtz, on the properties of sound waves”.

Waves and Sound

These three were Edwin Arnold’s ‘Light of Asia’ which is the biography of Lord Gautama Buddha. Second one is titled ‘The Elements of Euclid’, is a treatise on Classical Geometry. ‘The Sensations of Tone’ is the last one and was written by German researcher Helmholtz, on the properties of sound waves”. These books have impacted Raman’s working style and critical thinking nature in his later life. It started with his Masters’ in Physics in Presidency school, Madras.

When there was a discourse hung on how light that fell on a screen placed in its way would get diffracted, or bent, when entering a tight slit in it. While the whole class was pre occupied with it, Raman thought about what might happen whether the light shone straight, not from an angle, on the screen. No student could show such elective reasoning as Raman. He contemplated it as well as published an research paper on it in Philosophical Magazine, a British Journal. He was the among the pioneer from Presidency school to publish an research paper. The sign of the extraordinary mind proceeded in his later research on melodic instruments.

Raman was entranced by waves and sounds and constantly carried in his mind the memory of reading Helmholtz’s book on ‘The Sensations of Tone’ in his school days. He got an opportunity to study and experiment in the IACS, he studied musical instruments first. He utilized a thought found in Helmholtz’s book, he clarified the working of the Ektara, which is a simple instrument made of a resonant box and a string extended to lie across the cavity. Beginning from his comprehension of this simple instrument, he created numerous thoughts that he called ‘remarkable resonances’. Amid this time, he took up the violin for study and built up a method for developing the quality instrument.

It was the first run a scientific understanding was built up, and it is utilized even today. Raman’s investigations on the violin were broad and published as a book entitled ‘On the Mechanical Theory of Musical Instruments of the Violin Family with Experimental Results: Part I.’ Raman’s revelation, while his voyage across the Mediterranean sea, that water molecules could scatter light simply like air molecules was essential and radical back then. It set him on the track to finding the popular Raman’s Effect. In 1922, he composed a splendid essay titled, “The Molecular Diffraction of Light”, in which he theorized that light may exist in quanta, that is, massless particles of energy. This is an acknowledged theory till today yet was most radical back then. In this way, the extraordinary personalities whom Raman read during his youth considered his scholarly and proficient career.

Ans. The day when Raman walked into the Indian Association for the Cultivation of Science a historic moment because the building that became the laboratory where he and his team performed the legendary experiments on light.

5. Outline the subject of the first research Raman conducted in the IACS ?

Ans. The first research Raman has chosen was studying musical instruments. He explained the working of the ektara. He developed several idea that he called, ‘remarkable resonances’. He took up a violin for study and developed a way of characterizing the quality of the instrument. This was the first time a scientific understanding was established, and it is used even today.

6. What discovery did Raman make during his voyage across the Mediterranean and how did it prove to be important ?

Ans. Raman discovered that water molecules could scatter light like air molecules, during his voyage across the Mediterranean. It set him on the track to discovering the famous Raman effect.
