New Delhi: The progress of human civilisation has always depended on the progress of science, making them directly proportional to each other. Throughout the history, the evolution of science has resulted in the production of improved technologies which, in turn, has improved the comfort of our lives. Science is essential for the advancement of our society, for without it, we would still be in the ancient times.
Every year on February 28, National Science Day is celebrated to mark the discovery of the Raman effect by Indian physicist Sir CV Raman on February 28, 1928. Since 1986, the day has been celebrated every year. In this article, we will take a look at the theme of this day.
What is the theme of National Science Day this year?
This year, the theme of National Science Day is ‘Empowering Indian Youth for Global Leadership in Science and Innovation for Viksit Bharat’. In Delhi, the Department of Science and Technology (DST) will organise a day-long celebration on February 28. The theme highlights the need to empower the young citizens of our country and prepare them to take on a prominent role for global leadership in science and innovation which will result in the development of India, fulfilling the dream of a Viksit Bharat.
Prime Minister Narendra Modi has encouraged young students to live the day as a ‘scientist’ by spending time in research laboratories, visiting planetaria, and exploring space and science centres. Among the many events on the day to showcase the various facets and importance of science, a science quiz competition on the national level named Vigyanotsav will take place. The day will be celebrated by various scientific institutions across the country.
What is Raman effect?
Raman effect or Raman scattering is defined as the inelastic scattering of photons by matter, which means that there is both an exchange of energy and a change in the direction of light. Typically this effect involves vibrational energy being gained by a molecule as incident photons from a visible laser are shifted to lower energy and is known as Stokes-Raman scattering. In 1928, legendary Indian scientist CV Raman discovered it with the help of his student KS Krishnan. In 1930, Raman was honoured with the Nobel Prize in Physics for this discovery. In 1923, Adolf Smekal predicted the effect theoretically.
National Science Day, celebrated annually on February 28, commemorates CV Raman’s discovery of the Raman effect in 1928. This year’s theme, Empowering Indian Youth for Global Leadership in Science and Innovation for Viksit Bharat, emphasizes nurturing young scientists. knowledge Knowledge News, Photos and Videos on General Knowledge
