The Minister stated that the Global Science for Global Wellbeing theme was selected to increase public awareness of scientific issues in a global context that have an impact on global well-being.

Under Prime Minister Narendra Modi, India has acquired global visibility in the community of nations, and “we are ready for outcome-oriented global collaboration to address global challenges,” Singh stated. He stated that when concerns, challenges, and benchmarks have taken on global proportions, the remedy must also be global.

Principal Scientific Advisor Ajay Kumar Sood explained the rationale behind the theme “Global Science for Global Wellbeing” and stated that as a result of Covid-19, the international community has become more united in its efforts to combat global challenges. Sood also elaborated on the fact that on February 28, 1928, the renowned Indian physicist C.V. Raman made a significant discovery known as the Raman Effect.

When a beam of coloured light entered a liquid, it was discovered that a portion of the light scattered by the liquid was of a different colour. Raman demonstrated that the nature of this scattered light depends on the sample type present.
