Sir C.V. Raman - A tribute to an great scientist

This article is about a person who has started as an genius in the tender age of 13 and completed his M.A. [Hons.] in the age of 15 and both the degrees with gold medals, appointed as Assistant Accountant General at Kolkata at the age of 18, it is about Sir C.V.Raman of 'Raman's Effect' discovery.

He was born in the year 1888 in the month of November on 7th, he was in Tiruchirapalli in Tamil Nadu, he have an immense influence from his father as his father was an lecturer in mathematics and physic due to this fact he was immersed in an academic atmosphere. He was brilliant from his childhood, he had finished secondary education at an early age of thirteen, later he joined Mrs. A.V.N.College at Vishakapatnam in Andhra Pradesh, after two years he joined the famous Presidency College in Chennai, when he received his B.A. Degree with honours in Physics and English with distinction along with a gold medal, at that time he was just fifteen years old, later he continued his studies at Presidency College itself and received his M.A. in honours, later he joined Indian Audit and Accountant General in the Finance Department at Kolkata, this was the place where he got his interest of working with the subject science, he started attending the Indian Association for the Cultivation of Science and in the spare time he used to spend time studying physics or with stringed instruments and drums.

C.V.Raman’s elder brother was in services at Indian Audit and Accounts Service, as this influence Raman also to do that, he took up that competitive exam, the previous day of this exam he got his results of M.A. Honours, he had passed in the first class and recorded the highest marks scored by ever till that period in the Madras University, and later he passed I.A.A.S. examination too in distinction.

In the year 1907, he got married to Lokasundari Ammal, at the age of only nineteen he was in a high profiled job as Assistant Accountant General in the Finance Department in Kolkata.

In the year 1917 he gave his job with finance department and joined as Professor of Physics in the University of Kolkata, where has made numerous experiments and made enormous contributions.

Till the year 1909, Burma was part of India and Raman got transferred to Rangoon, he came back to Madras as his father was passed away, later he continued his research work in the laboratories of Madras University.

In the year 1915 the Kolkata University stated a Science College, a physics chair was also established and Raman appointed as Professor there, this was the reason for the leaving away his high profiled and powerful job, which brought him a high salary to him

In the year 1913 the Indian Science Congress was started and the main aim was to bring all scientists together who are engaged in research work, this was a platform to exchange their ideas for research work, Raman was the president of this congress at that time, he has presided over the annual congress meetings from 1929 to 1948.

Raman went to England in the capacity as the representative of Kolkata University in the year 1921 and incidentally this was his first visit to abroad, he gave brief lecture at Physical Society, later he was introduced to J.J. Thomson and Rutherford, both of them were British Physicists.

Raman’s journey to England was by sea, in the leisurely hours he was sitting on the upper deck and used to enjoy the beauty of the water in the vast sea, the blue color of the water in the Mediterranean sea grabbed his interest, later he thought is that blue color due to reflection of the sky, if not he it would be blue even in the absence of light, later he though it is due to scattering of the sun and its light absorbed by water molecules. When he returned to Kolkata, these ideas pushed him to spend more time in laboratories, he took a month’s time to prepare a research paper and sent that to Royal Society of London, and later it was published as a lengthy article on the molecular scattering the light.

Kolkata laboratory contained several scholars to unlock the sound and light secrets, but to all of them Raman was the mentor and the leader, later along with his students he had several research work on scattering of light in the liquids like pre water and also alcohol and also in vapors and gases.

Later in the year 1926 he started the publication of his research papers and he wanted the youngsters to work with him and he used to asked them to take up independent positions and to serve the nation as well, his research work on sound became famous globally, a German Encyclopedia in Physic, published his research works in the year 1927 and he was the first and the only foreign scientist who was invited to publish his article in that book.

Many times when a rainbow appears and which delights our eyes, but we used to see the shades of red, orange, yellow, green, blue, indigo and violet, as the while ray of the sun which includes all these colors, and a sunlight bean passes through a glass prism a combination or a patch of these colors are seen, this is called as spectrum, and an device called spectrometer which is used to study the spectrum, Raman spent a lengthy day to study and came to the conclusion that the incident light may be monochromatic as the scattered light passed through that transparent substance, in the year 1928 the South Indian Science Association and Science Club of Central College in Bangalore organized a meeting and Raman was the chief guest, he explained the phenomenon of his discovery in detail which later became the most famous ‘Raman Effect’, the scattered lights which contained spectral lines called as ‘Raman Lines’. His research and discovery confirmed that the light was made up of several particles known as protons, later this discovery helped to study the crystal structures in different substances.

After several experiments and discoveries the word Laser which literally means Light Amplification by Stimulated Emission of Radiation come in to effect in the year 1960, as this research helped to get monochromatic light of intensity in very high range for the sake of experiments.

Several honors for his greatest achievements came to him from all over the world, in the year 1928 the Science Society from Rome awarded him the prestigious Matteucci Medal in the year 1929 the British Government knighted him with ‘Sir’ hood, then the next day onward he became ‘Sir C.V.Raman’. The Hughes medal was awarded to him by the Royal Society of London and several honorary doctorates from Glasgow, Paris, Bombay, Banaras, Dacca, Patna and Mysore.

A writer can get a highest award is Nobel Prize, Raman awarded with this prize award in the year 1930, till that time no Indian or Asian has received that award, in that award ceremony he used alcohol to demonstrate his Raman effect.

In the year 1933 he came to Bangalore as the Director of Tata Institute which is now called as the Indian Institute of Science, there he studied the theory of crystals, the diffraction of light by ultrasonic waves.

To accomplish his studies the Government of Mysore granted 24 acres of land for the promotion of his activities in the academy, he established a research institute at Hebbal in Bangalore, he gave away all his property to this Institute, later this academy called as ‘Raman Research Institute’.

The Government of Mysore granted 24 acres of land to promote the activities of the Academy. It was his earnest desire 'to bring into existence a centre of scientific research worthy of our ancient country, where the keenest intellectuals of our land can probe into the mysteries of the Universe'. He fulfilled his wish by establishing a Research Institute at Hebbal, Bangalore. He did not seek help from the Government but have away all his property to the Institute. The Executive Committee of the Academy named the centre 'Raman Research Institute'.

In the year 1984, he was honored with the highest civilian award one can get as an Indian, the ‘Bharata Ratna’ from the Government of India.

A few days later in the year 1970, due to relentless and restless researches and discoveries he got an heart attack, but later at the age of 83 Sir. C.V.Raman passed away in the year 1970 on 21st day of November.

Raman as a little boy possessed curiosity to know everything and that intuition of a great genius to understand everything behind the nature which was hidden as secret till then, the life of this greatest scientist of all times was truly the life of an great seer.

There would not have been any child who had not asked at least once to his parents why the sky is blue or why the sea is blue. He probably would have got the answer for sea. They would have told him that the blue of the sky is reflected in the sea. But then what about the blue of sky? Probably it would have taken a few more years until his science teacher would have cleared his doubts and telling him about the 'Raman effect'.

After Isaac Newton, probably it would have been C.V.Raman who would have kindled the scientific mentality of an Indian student. Newton because the falling apple is taught well, before Raman Effect.

Even though India has a very large source of scientific talents, it is irony that there is no Nobel Prize to India in physics after C V Raman.

C V Raman is still shining as a beacon to Indian science. The author deserves sincere thanks for this article as tribute to the great scientist.
