National Science Day Why is National Science Day celebrated on 28 February?

Science News Desk – It may come as a surprise that the National Science Day in India is not dedicated to the birthday or death anniversary of a great scientist. Not only this, in fact it is not dedicated to any scientist but the achievement of a great scientist. The day of 28 February is recorded as a very important day in the history of India. On this day in 1928, the first major scientific discovery was made in India, due to which National Science Day is celebrated in India on 28 February because on this day Indian scientist CV Raman made the biggest discovery of his life, on which he was awarded the Nobel Prize.

what was that discovery
This was the first time that an Indian had received the Nobel Prize for Science. His discovery is known as Raman Effect. In honor of this discovery of Dr. CV Raman, National Science Day is celebrated with the aim of encouraging the young scientists and children of the country.

who recommended
In 1986, the National Council for Science and Technology Communication recommended to the Government of India that National Science Day should be celebrated in the country on 28 February every year. Today this day is celebrated in all the schools, colleges, universities and other educational, scientific, technical, medical and research institutions of the country.

multiple programs
This day is being celebrated across the country since 28 February 1987 and from the year 2020, scientific awards are also given for making special contributions in the field of science and communication to encourage science in the country. On this day many activities like public lectures, science related programs on Radio TV etc., science films are shown and scientific exhibitions are organized across the country.

But why the discovery of CV Raman?
CV Raman discovered the Raman effect in 1921 while returning from Bombay by ship to London, without extensive research and expensive equipment, while searching for an answer to a very simple question, whose impact was so profound in the science world that the British Nobel Committee could not hesitate to award the Nobel Prize to

what was that question
Returning to India from London on the fifteenth day of the journey, CV Raman was doing some contemplation in the evening. Then he was attracted by the deep blue color of the Mediterranean Sea and the question arose in his mind as to why this color is blue. This question was deeply seated in Raman’s mind. He did many experiments to get the answer and finally got success on 28 February 1928.

what is the raman effect
The Raman effect is actually the process of scattering or scattering of light due to the particles of the medium. It occurs when light enters a medium which changes its wavelength. When a ray of light passes through a transparent chemical, a part of the light changes its direction. This effect is called Raman effect.

Due to the scattering of these light, the lines formed in the spectrum were later called Raman lines, which are actually made of Raman effect. The Raman effect made its way into spectrometry, giving rise to Raman spectrometry, which has many uses in physics and chemistry. The scientists of the world readily accepted the Raman effect. The Raman effect was mentioned in nearly 700 research papers in the first seven years of its discovery. This is a very inspiring discovery which proves that a scientific attitude in every individual can make great discoveries.
