National Science Day 2023: It is observed on 28 February to commemorate the discovery of the  'Raman Effect'. In 1986, the Government of India designated 28 February as National Science Day (NSD). On this Day, Sir Chandrasekhara Venkata Raman, also known as CV Raman announced the discovery of the 'Raman Effect' for which he was awarded the Nobel Prize in 1930.

Union Minister of State (Independent Charge) Science & Technology; Minister of State (Independent Charge) Earth Sciences; MoS PMO, Personnel, Public Grievances, Pensions, Atomic Energy and Space, Dr Jitendra Singh said, "This is the best time to give a push to this integrative approach as all the ministries and departments have come together to work for the survival of humanity at the time of the pandemic crisis.”

National Science Day greetings to all scientists and science enthusiasts. Let us reaffirm our commitment towards fulfilling our collective scientific responsibility and leveraging the power of science for human progress.

Scientific development has changed the life of human beings many folds. Science has made lives better and easy for human beings. Robots, computers, Mobile, etc. have been invented with the help of science only. Therefore, science holds great importance in our lives. India has also contributed a lot to the field of science. Many great scientists were born in India and recognized India in the field of science and made a separate place too. 

In 1928 an Indian Scientist Sir Chandrasekhara Venkata Raman discovered a phenomenon known as  Raman Effect for his remarkable discovery in 1930, he was awarded a Nobel Prize, which was the first Nobel Prize in India in the field of Science and to mark this discovery every year National Science Day is celebrated.

Sir Chandrasekhara Venkata Raman was a Tamil Brahman who had worked from 1907 to 1933 at the Indian Association for the Cultivation of Science, Kolkata, West Bengal. Here, he had researched various topics of physics of which one is the Raman Effect, which marked the greatest discovery in the field of science in Indian History.
In 1986, the National Council for Science and Technology Communication (NCSTC) asked the Government of India to designate 28 February as National Science Day. The government had accepted it and declared 28 February as National Science Day in 1986. The first National Science Day was celebrated on February 28, 1987.

What is Raman Effect?

It is a phenomenon in which a change in the wavelength of light occurs when a beam of light is deflected by molecules. When a beam of light travels from a dust-free transparent sample of a chemical compound, then a small fraction of the light emerges in a direction other than that of the incident light. Most of the scattered light wavelength is unchanged and in small part, if the wavelength is different from that of incident light it is due to Raman Effect.

Awards which were won by CV Raman are Fellow of the Royal Society (1924), Knight Bachelor (1929), Nobel Prize in Physics (1930), Bharat Ratna (1954), Lenin Peace Prize (1957) and Fellow of the Royal Society (1924).

The entire nation celebrates it as a science festival by organising workshops, exhibitions of science movies, an exhibition based on themes and concepts, live projects, debates, quiz competitions, seminars, etc. Its main aim is to provide scientific temper in the minds of people of all age groups. A large number of people gather together and attend National Science Day celebrations with great enthusiasm and participate in activities like quiz competitions, debates, projects, etc.
Major scale celebrations held at The Indian Department of Science and Technology, The Giant Metre wave Radio Telescope (GMRT), The Councils of Science and Technology in every state, The Defence Research and Development Organisation (DRDO), The CSIR-National Environmental Engineering Research Institute (CSIR-NEERI) and at The Jawaharlal Nehru Planetarium.

Objectives behind the National Science Day celebrations are:

- To spread the message of the importance of science and its application in the daily life of people this is necessary to accelerate the pace of development.

- Invent and implement new technologies for the development of science.

- For human welfare also it is necessary to understand and display efforts and achievements in the field of science.

- To provide an opportunity for people who want to develop their carrier in the science field.

- To encourage people and popularise Science and Technology.

- Despite many significant achievements, certain sections of our society are still guided by blind faith and beliefs, which is reflected in the quality of decision-making on developmental issues that required change.

At last, let us find out some technologies that have transformed the lives of people specially-abled.

- There was a person named Neil Harbisson who was born with Achromatopsia condition in which he can only see black and white colours. Then, with the help of science, he created a camera that curls over the head like an antenna and converts colour inputs into some specific sounds that help people listen to colours. Isn’t it amazing!

- Liftware Company had created a magic tool for persons suffering from Parkinson’s disease. This machine uses hundreds of algorithms and helps people with this disease and supports their food consumption. The hand of the patient is monitored by this machine.

- Have you ever heard about Para Technology a Leicestershire-based firm that created a working prototype is called Anagraphs? It uses software-controlled heat to expand paraffin waxes in its screen, turning the material from liquid to solid and controlling the main features of the prototype, which are raised.

With all these examples we come to know that Science not only provides a good career opportunity but also is very useful in our daily life which transforms our lives and also provides a new direction to think, invent new technology as seen above etc.
