Biography Of CV Raman
Nobel Prize winner; Bharat Ratna Sir Chandrasekhar Venkataraman was a great physicist. His research in the field of light scattering means that when light passes through a transparent object, the wavelength of deflated light changes somewhat. This process is known as Raman effect. Come, today, on the occasion of his birth anniversary, November 7, we know about his great life.

Birth and Education
Chandrasekhar Venkataraman was born on 7 November 1888 in Tiruchirappalli, Tamil Nadu. His father Mr. Chandrashekhar Iyer was a lecturer in mathematics and physics. His mother, Mrs. Parvati Ammal was a woman from a cultured family. Hence, from the very beginning there was an educational atmosphere in the house which attracted the boy Venkat towards science. Venkataraman's primary education took place in Visakhapatnam. While for higher education he went to the Presidency College in Madras.
Chandrasekhar Venkataraman was a student of sharp intellect since childhood. He passed the matriculation examination at the age of 11 and the intermediate examination at the age of 13.
In 1904, he passed the B.A. examination from the University of Madras. He not only came first in this examination but he was also awarded a gold medal in physics. After this, in 1907, he completed his M.Sc.
While studying M.Sc, he wrote a paper on the subject of acoustics and optics which was published in London Philosophical Magazine in 1906. At that time, he was only 18 years old.
Government Job
At the time of Sir CV Raman, more Indians were not interested in science. Chadrashekhar Venkataraman had not even thought of becoming a scientist yet. That is why he sat in one of the most difficult competitive examinations of that time and came first. As a result, he was elected to a prestigious post like Assistant Accountant General.
Love Marriage
One day cv Raman saw a girl playing Veena. The name of that girl was Lok Sundari. He liked the melodious Veena of Lokasundari so much that he gave him his heart. He expressed his desire to marry Loksundari and wanted to meet her parents next day without any delay.
CV Raman was a public servant, so immediately her parents became agree for their marriage, and soon both of them got married . Cv Raman moved to Calcutta after along his wife . Loksundari was a skilled housewife and always kept her husband free from the worries of the house which led to Sir C.V. Raman was able to concentrate his research in physics.
Moved Toward Science
If Raman wanted, he could do this job of rest and status all his life. But it says -
‘’The greatest identity of a great man is that he does not remain satisfied and sit.’’
CV Raman was also a person of such mood, he was not satisfied with his government job because his destination was different.
While returning from office, one day he suddenly noticed an institution, and he just went to meet that organization, that name was "The Indian Association for the Cultivation of Science". In those days, Dr. Ashutosh Dey took over the charge of that institution. This institution was founded by the Amritlal government.
In the first meeting after with CV Raman, the Amritlal government had guessed that C.V. Raman is a high-profile scientist. He immediately gave Raman the key of the institution, and from the very next day he started doing his research work in that institution.
CV Raman Resigns From Government Job
In the year 1917 after working for ten years, C.V. Raman said goodbye to the government job. At that time he got a proposal for teaching physics in a new science college in Calcutta, which he accepted and he got involved in that work. Working with science related college , Raman got a lot of satisfaction. The students of that college were also very impressed with Raman's education. In a short time he became the favorite teacher of all the students.
While in college, CV Raman started calling talented students from every corner of the country and gave them guidance. Apart from teaching work, he also spent a lot of time in the laboratory.
CV Raman's aim was that if he stay in a college related to science, then he will be able to do my research work very easily. While doing laboratory management and teaching work, he got the facility of staying in the same college housing area.
Discovery of Raman Effect - 1928
The Raman effect was the discovery for which the world still remembers Sir CV Raman and for which he was awarded the Nobel Prize. He made this discovery on 28 February 1928 after years of research with some of his disciples.
This discovery revealed that -
‘’When light passes through a transparent medium, whether solid, liquid or gas, its nature and behavior changes.’’
This discovery is used to understand the internal structure of various chemical compounds.
A German scientist Peter Pringsheim called this process as ‘’Raman Effect’’.
He was awarded the Nobel Prize in Physics in 1930 for this great discovery.
Raman Research Institute
Sir CV Raman founded Raman Research Institute, Bangluru in 1948 to promote scientific thinking and research. He spent a large part of his life in the laboratories here and he later died in this institution.
Sir C.V. 10 interesting things related to Raman's life:
1. In the year 1922 C.V. Raman published a monograph titled "Molecular Radiation of Light". In this study, he studied the changes in the colors of light to investigate the scattering of light.
2. In the year 1924, his disciple S. Krishnan noticed the dim fluorescence. Then cv Raman entrusted his disciple Venkateswaran to work out the details of his order, but for some reasons he could not fulfill this responsibility.
3. In the year 1927 C.V. Raman went to Waltair, where he wrote an article about Crompton's influence. After returning to Calcutta, he was entrusted with the task of monitoring the activity of fluorescent and light scattering to his disciple Venkateswaran. Venkateswaran's experiments proved that dim fluorescence was more pronounced in glycerin. This important Taran proved that this incident involving light is not just fluorescent.
5. Krishnan's many experiments were carried out by C.V. Raman investigated and on 28 February 1928, his research work was completed. This greatest discovery of his life was known as "Raman Effect".
6. His most famous discovery was the "Raman Effect". This invaluable discovery was made by him on the day of February 28, so that auspicious day is celebrated every year as National Science Day.
7. In the year 1930 C.V. Raman was selected for the Nobel Prize. CV for the most prestigious Nobel Prize Raman's name was proposed by renowned scientists such as Nils Boer, Ruther Ford, Charles KB, Eugene Lak, and Charlson.
8. In the year 1952 C.V. There was a proposal to elect Raman for the post of Vice President of India. He also got unquestioned full support. He was almost certain to be sitting on this post. But C.V. Raman had no interest in politics and did not even crave rest, so he respectfully refused to accept this glorious post.
9. In the year 1954 C.V. Raman was awarded the Bharat Ratna Award.
10. In the year 1957 C.V. Raman was awarded the Lenin Peace Prize of Russia.
The Death
Even at the age of 82, Sir CV Raman was working in his lab in Bangalore and suddenly succumbed to a heart attack. The doctors made it clear that they now have only a few days left to live and advised them to stay in the hospital. But he wanted to spend his last time on the campus of Raman Research Institute and went there. This great figure died on the morning of 21 November 1970. Two days before he died, he said-
Do not let the journals of this academy die, because they are sensitive indicators of the science being done in the country and whether the roots of science are strengthening in it or not.
Cv Raman may not exist among us today but his invaluable achievements and scientific discoveries are immortal. His life character will remain an ideal model and inspirational for many new science students and scientists to come.
