In India, February 28 is celebrated every year as 'National Science Day'. On the same day in 1928, the great scientist Chandrasekhar Venkataraman (CV Raman) discovered the unique 'Raman effect' in the field of physics. Raman's discovery was a clear demonstration of the Quantum Theory of Light.

The decision to celebrate National Science Day was taken by the Government of India in 1986. Science Day is associated with a theme every year by the Government of India. The role of women in the country's prestigious space missions Chandrayaan and Mangalyaan has been crucial in the last few years.

The theme of National Science Day 2020 is 'Women in Science'. The main objective of this theme is to further promote the participation of women in the field of science dissemination, promotion, dissemination and research.

What is the theme of National Science Day 2021?

This year, the theme of National Science Day 2021 is "The Future of STI: Impact on Education, Skills and Applications"

What is the purpose of National Science Day?

The purpose of this day is to motivate students to try their hand at science.

CV Raman was the first Indian scientist to win the Nobel Prize in Science. This great scientist was born on 7 November 1888 in the small town of Tiruchirappalli (Tamil Nadu) in southern India. Raman's father was a professor of mathematics and physics at the college. Raman passed the FA exam at the age of 11 with a tenth and at the age of 13 with a scholarship.

After completing his primary education, he joined AVN College, Visakhapatnam (Andhra Pradesh). At the age of fifteen, CV Raman earned a BA degree and finished first in his class. At the age of eighteen, he earned his M.A. Received Honors degree. During his student days, he conducted research on many scientific subjects at his own level and one of his research papers was published in 1906 in Philosophical Magazine, London.

Raman married Lokasundari Ammal (1892-1980) on 6 May 1907. He had two sons, Chandrasekhar and Radio Astronomer Radhakrishnan. CV Raman Subramanian was one of Chandrasekhar's uncles who won the Nobel Prize in Physics in 1983. Of course the CV. Raman showed his expertise in science but was not encouraged to choose science as a profession at that time and at the behest of his father, he appeared for the entrance examination in 'Indian Financial Civil Services'.

After passing the examination, he got a job as Assistant Accountant General in the Revenue Department. While working in the Calcutta office of the department, he met Amrit Lal Sirkar, Honorary Secretary, Indian Association for Cultivation of Science. At the behest of the government, Raman started doing research in the association's laboratory. While working here, he wrote about 30 research papers.

His research was published in some of the best science journals such as Nature, Physics Reviews and Philosophical Magazine. He was also transferred twice during this period but continued his research work.

When the great scientist Ashutosh Mukherjee became the Vice-Chancellor of Calcutta University in 1917, he was. Also. Raman was offered a professorship, which he gladly accepted. Although his salary was half of his first job, he did not take a minute to quit his job in the revenue department. The Revenue Department did not want to let him leave because he was one of the best officers.

When he went to England in 1921 to work at the university, he was fascinated by the deep blue oceans there. Looking at these oceans, CV Raman came up with the idea of doing research on the subject of light scattering. In 1924 he was elected a Fellow of the Royal Society of London.

Four years later, in 1928, at a joint meeting of the Institute of South Indian Sciences and the Science Club of Center College, Bangalore, he announced his discovery of the Raman effect. For his research work in the field of science, he was awarded the title of 'Sir' in 1929 and the Nobel Prize in 1930. In 1934, he became the Director of IISC, Bangalore where he remained till his retirement.

After his retirement, he established the Raman Institute in Bangalore and later the Indian Academy of Sciences. He was awarded the Bharat Ratna in 1954 by the Government of India for his scientific contribution. He died on November 1, 1970.

According to his wishes, his activities were performed in the garden of Raman Institute. He was a simple, passionate man. He was of the view that the solution to India's problems lay only with science and that we should not look to the West for solutions to our problems but should find solutions to them ourselves.

Raman was not only a great scientist but also a staunch patriot. Throughout his life, Raman had amassed a collection of nuggets, minerals and other interesting items which are on display at the Raman Research Institute where he taught and worked.
