Theme of National Science Day 2022
The theme of National Science Day 2022 is ‘Integrated Approach in S&T for a Sustainable Future’. The theme follows a four fold approach consisting of integration of all the scientific departments which can work on theme based approach and extended scientific integration encompassing engineering, medical, and other institutions.
History of National Science Day
In 1986, the National Council for Science and Technology Communication (NCSTC) asked the Government of India to designate February 28 as National Science Day. The event is now celebrated all over India in schools, colleges, universities and other academic, scientific, technical, medical and research institutions. The first NSD was celebrated on 28 February 1987.
Significance of National Science Day
National Science Day is celebrated in India on 28 February each year to mark the discovery of the Raman effect by Indian physicist Sir C. V. Raman on 28 February 1928. For his discovery, Sir C.V. Raman was awarded the Nobel Prize in Physics in 1930.
National Science Day is celebrated to spread a message about the importance of science used in the daily life of the people. To display all the activities, efforts and achievements in the field of science for human welfare. It is celebrated to discuss all the issues and implement new technologies for the development in the field of science. To give an opportunity to the scientific minded citizens in India. To encourage the people as well as popularize science and technology.
What is the Raman Effect?
Raman Effect is a phenomenon in spectroscopy discovered by the eminent physicist while working in the laboratory of the Indian Association for the Cultivation of Science, Kolkata.
Raman Effect, change in the wavelength of light that occurs when a light beam is deflected by molecules. When a beam of light traverses a dust-free, transparent sample of a chemical compound, a small fraction of the light emerges in directions other than that of the incident (incoming) beam. Most of this scattered light is of unchanged wavelength. A small part, however, has wavelengths different from that of the incident light; its presence is a result of the Raman Effect.
Conclusion
National Science Day is celebrated all over India in remembrance of great scientists, the students of the schools and colleges demonstrate various science projects as well as national and state science institutions demonstrate their latest researches. The celebration also includes public speech, radio-TV talk shows, exhibitions of science movies, science exhibitions based on themes and concepts, watching night sky, live projects and research demonstration, debates, quiz competitions, lectures, science models exhibitions and many more activities.
