Significance of National Science Day 2025

National Science Day, observed every year on February 28, celebrates the groundbreaking discovery of the Raman Effect by Sir C.V. Raman in 1928—a discovery that earned him the Nobel Prize in Physics in 1930. This day serves as a tribute to India's scientific advancements and aims to inspire innovation and curiosity among students, researchers, and science enthusiasts.

In 2024, National Science Day focused on promoting scientific temper and recognising the Significance of National Science Day in shaping India’s progress. From its historical roots to this year’s theme, celebrations, and impact, let’s explore why this day holds immense importance in fostering a culture of scientific excellence.

History of National Science Day

In 1986, the National Council for Science and Technology Communication (NCSTC) asked the Government of India to declare 28th February as National Science Day (NSD). This was done to honour Sir C.V. Raman’s discovery of the Raman Effect and to recognise the efforts of other Indian scientists in the field of science.

The government approved the request, and the first National Science Day was celebrated on 28th February 1987. Since then, it has been observed in schools, colleges, universities, and research centres across India. To encourage more people to talk about science, NCSTC introduced the National Science Popularisation Awards, which reward those who help spread knowledge about science.

National Science Day reminds us of the importance of science in daily life and encourages young minds to explore and learn. 

The Raman Effect

The Raman Effect is a scientific phenomenon discovered by Sir C.V. Raman on 28th February 1928. It refers to the scattering of light when it passes through a transparent substance, such as a liquid or gas. Some of the scattered light changes its wavelength due to interactions with the molecules of the substance.

Key Points About the Raman Effect:

• When light passes through a medium, most of it scatters without any change in wavelength.

• However, a small part of the light changes wavelength due to energy exchange with the molecules in the medium.

• This shift in wavelength is known as the Raman Shift, and it helps scientists study the composition and properties of materials.

Why is it Important?

• The Raman Effect proved that light can interact with matter in new ways, leading to advancements in physics and chemistry.

• It is widely used in Raman Spectroscopy, a technique that helps identify substances based on their molecular structure.

• The discovery earned Sir C.V. Raman the Nobel Prize in Physics in 1930, making him the first Indian to win a Nobel Prize in science.

The Raman Effect remains a crucial concept in scientific research, with applications in medicine, material science, and space exploration.
