Chandrasekhara Venkata Raman was born in Tiruchirappalli in Southern India on November 7, 1888. His father was such a mathematician and physicist that from the beginning he was immersed in the spirit of education. He entered the Presidential College, Madras, in 1902, and in 1904 passed the B.A. testing, winning first place and a gold medal in physics; in 1907, he received his M.A. degree., received the highest division. His first research on optics and acoustics – two fields of research he devoted to all his work – was done while he was a student. Since at that time scientific work did not seem to offer very good opportunities, Raman joined the Indian Finance Ministry in 1907; although the work of his office took up most of his time, Raman had the opportunity to conduct experimental research at the Indian Association for the Cultivation of Science in Calcutta (he became its Honorary Secretary in 1919). Although much has been written about Sir C V Raman, a scientist, little is known about him as a man and a teacher.
Curiosity like a child – a desire to understand the things around him
Many people believe that Sir C V Raman was a born genius, which explains many of his achievements. While this is true, it is not the only reason. In his autobiography published by the Indian Academy of Sciences, author S Ramaseshan, also a scientist, writes, “For Raman, the work of science was to fulfil an inner need. His scientific approach was one of love, curiosity, and simplicity. It was an effort to understand. To him science was based on independent thinking, combined with hard work. Science was a personal endeavor, a pursuit of beauty and above all a pleasurable experience. ” Many reminders about Raman speak of his child-like curiosity about run-of-the-mill mirrors. For him, the simplest observation he could make by simply glancing around at her deserved deep scientific scrutiny. Through his many discoveries and successes, he repeatedly demonstrated that a deep understanding of these everyday events opened the way for the discovery of the basic laws of science.
Joie de vivre – the endless zest of life
We have all seen the sea appear blue, but we know from experience that life is completely colourless. Have we ever wondered why water appears to have this colour in rivers and seas? This was the line of thought that led to the discovery of the Raman effect. The highest civilian award of the Republic of India is known as BHARAT RATNA.
Sir CV Raman is known for his confidence and work ethic. In fact, Max Born, a German physicist, once said: “Raman’s instinct is to jump on the mat. No one can compare to him in power or strength. ” He was so famous for his infectious pleasure, that talking to him for a while was like taking a tonic. Those who knew him often spoke of his deep love and concern for the environment — the colors of birds, the beetles, the blue light, the spectacular colors of corona, the splendor of the sun and the moon. , as well as the amazing beauty of minerals, crystals and gems. This not only pleased him but also formed the basis for his scientific studies. Ramaseshan also mentions such an episode, writing ‘One night, while pointing to the sky, Sir C V Raman said: “Have you seen anything good?” Above, one saw small, multicoloured clouds pass over the Moon, which glistened on the shiny leaves of the trees. “This is a pleasure,” she said. “That we should live, and that we should naturally be given the ability to see.”

Sun Corona
The Corona of the Sun is the outer part of the Sun’s atmosphere. The corona is often obscured by the bright light of the Sun’s face. That makes it difficult to see without the use of special equipment. However, the corona can be viewed during a total eclipse.
The discovery of the Raman Effect is the story of a single-minded man who pursues his sacred wisdom through perseverance and perseverance that is rarely seen in humanity. On his first trip to Europe in 1921, the fascinating beauty of the Mediterranean fascinated him. Lord Rayleigh, a British scientist, was of the opinion that this blue colour was due to the blue light in the water. Raman denied this with a simple test he did on the ship. He saw a blue light with Nicol’s prism on Brewster’s angle and found that the colour blue was “far from being poor due to the pressure of the blue appearance has improved dramatically”. He pointed out, then, that blue is due to the scattering of cells. Man finds his life full of the same episodes. Episodes of not giving up his natural instincts, and incorporating hard work, time and thought into learning the truth.
It is believed that Sir CV Raman was probably the greatest science salesman he had ever been with. Many talented young men of his time took up science because they once listened to him once! As a teacher, he was well-known for his lectures. It was not just his habits or his grandeur — he made his audience roar with laughter. In his studies, he spoke only about the things he was feeling deeply about, the things he understood or wanted to understand. He saw things through their simple and basic elements. He made the audience feel like they could see for themselves (which they certainly did not see). When it came to teaching, he led by example. His talks opened the way for him to inculcate logical thinking in his students by engaging in discussions with students. The thing is that every good teacher lives to this day.
There are not enough words to describe the myth Sir CV Raman was. When you look closely at her life, it can be frustrating how all of her features are encouraging. Perhaps his most important health lesson would be – not to give up on me.
FAQs
What is the backstory for the origin of National Science Day?
At IACS, Raman conducted a challenging study that eventually won him the Nobel Prize in Physics on February 28, 1928. He found evidence of a quantum nature of light by observing the scattering of light, a known effect, as Raman Effect. This day is celebrated as National Science Day in India.
What do you think about Raman's Interest in the Dispersion of Light?
Fully educated in India, C.V. Raman made his first trip to London in 1921, when his reputation for the study of optics and especially acoustics was already well-known to English physicist J.-P. J. Thomson and Lord Rutherford, who gave him a warm welcome. Raman's speciality has been the study of vibration and sound of stringed instruments such as violin, Indian veena and tambura, and two distinct Indian percussion instruments, tabla and mridangam.
