Against the backdrop of India's rich heritage and traditions, there is a day that highlights the country's scientific ingenuity and creativity. On February 28 of each year, the country pays tribute to the remarkable achievements of its scientists and recognizes their pivotal role in driving progress and innovation.

But what is so special about this day and why is it celebrated as National Science Day? Listed below are answers to these frequently asked questions.

Why is National Science Day celebrated?

India celebrates National Science Day on February 28 every year to commemorate an important scientific event, namely the announcement of the Raman effect by C.V. Raman on February 28, 1928. This discovery, which earned Raman the Nobel Prize in Physics in 1930, is a testimony to the contributions of scientists That is indelible in the development of the nation.

What is Raman effect?

Central to Science Day celebrations is the Raman effect, a phenomenon in which light scatters after interacting with a substance, resulting in a change in the color of the resulting light.

For decades after the discovery of Rayleigh scattering in 1871, it was widely believed that the blue color of the oceans was due solely to the reflectivity of the sky. However, Sir C.V. Raman challenged this idea during a trip from London in 1921. His curiosity led him to explore molecular diffraction of light, which eventually led to the pioneering discovery of the Raman effect.

Since then, the Raman effect has fueled many scientific advances, facilitating the development of fundamental technologies to address countless global challenges. From discovering bombs and analyzing tablets, powders and liquids, to studying cancer cells and minerals on distant planets, scientists have harnessed this principle to address critical issues across diverse fields.

What is the theme of National Science Day 2024?

The theme chosen for this year's National Science Day celebration is 'Indigenous Technologies of Vixit Bharat' (Indigenous Technologies of Advanced India). It confirms the state's commitment to promoting local technological solutions for the well-being of society.

According to a statement issued by the Ministry of Science and Technology, the theme aims to enhance public appreciation for science, technology and innovation while highlighting the achievements of Indian scientists in leveraging indigenous technologies to address pressing challenges.

By emphasizing the importance of indigenous technologies, this year's celebration seeks to inspire collaboration between the public and scientific community, advance India's progress and contribute to global progress.
