National Science Day 2025, Overview, Theme, Day

National Science Day 2025 is celebrated on 28 February 2025 every year. This year the theme is “Empowering Indian Youth for Global Leadership in Science and Innovation for Viksit Bharat.” The day aims to honour scientific achievements like “Raman Effect” and inspire innovation among young minds. In this article, we are looking into the significance, objectives and contributions of this day. 

National Science Day 2025 Overview 

National Science Day 2025 is the day when the Raman Effect was discovered by Sir C.V. Raman in 1928. The goal is to promote science and technology, scientific thinking skills through conducting various events like debates, exhibitions, quizzes, and seminars. The day highlights the scientific advancements and inspires future generations to take up careers in science. 

National Science Day 2025 Theme 

National Science Day is celebrated every year with a new unique theme. The theme for the year 2025 is “Empowering Indian Youth for Global Leadership in Science and Innovation for VIKSIT Bharat.” The theme provides the outline of course of action for seminars and discussions to be held at the Vigyan Bhawan.

History of National Science Day 

The National Science Day was observed for the first time in 1987, proposed by the National Council for Science and Technology and Communications. The proposal was accepted by the government and 28th February was declared National Science Day to highlight the discovery of Raman Effect. 

India celebrates the day annually to honor the importance of science in progressing the society and serving a reminder of Indian scientific heritage and the contributions of scientists in global knowledge.

What is the Raman Effect?

Founded by C.V Raman and K.S. Krishnan in 1928, under the Raman Effect, the light underwent a shift in wavelength when interacting the molecules of substances. In this discovery, the effect demonstrated that light can be scattered, carrying valuable information about molecular vibrations. Ever since the discovery, this discovery has become an important tool in medicine, chemistry, physics and material composition and properties. This discovery helped him win the Nobel Prize in Physics in 1930.

Who Was C.V. Raman? 

Sir Chandrasekhara Venkata Raman, also remembered as C.V. Raman was an Indian physicist who made big contributions to spectroscopy and optics. He won a Nobel prize in 1930 for the discovery of the Raman Effect. He happened to be the first Indian scientist to receive a Nobel Prize in Physics and laid the foundation of modern spectroscopy. The Raman Research Institute was founded in 1948 and he also served as the Director of the Indian Institute of Science, Bangalore.

C.V. Raman’s Contributions 

Sir C.V. Raman made groundbreaking contributions to physics and scientific research, leaving a lasting impact across multiple domains:

• Raman Effect (1928): Explained the scattering of light and its interaction with molecules, earning him the Nobel Prize in Physics (1930).
• Acoustics: Conducted in-depth studies on musical instruments and wave propagation.
• Molecular Structure: Advanced the understanding of crystals and liquid structures.
• Diamonds & Iridescent Substances: Researched the structure of diamonds and the optical properties of iridescent materials.
• Literary Contributions: Authored key works, including Molecular Diffraction of Light, Acoustical Memoirs, and Why the Sky is Blue (co-authored).
• Institution Building: Founded the Raman Research Institute to foster scientific progress in India.

Significance of National Science Day 2025

National Science Day 2025 is a key event in fostering scientific awareness and innovation in India. Here’s why it matters:

• Honoring Scientific Excellence: Celebrates the contributions of Indian scientists, especially C.V. Raman.
• Inspiring Scientific Curiosity: Encourages students to explore science and research.
• Advancing Science & Technology: Showcases breakthroughs across various fields.
• Connecting Science & Society: Enhances public understanding of scientific progress.
• Strengthening Research & Education: Motivates young minds to pursue STEM careers.

This year’s celebration will highlight India’s scientific achievements and the lasting impact of the Raman Effect. By observing National Science Day, India reaffirms its commitment to scientific thinking and innovation.
