National Science Day: 28th February
National Science Day: 28th February
National Science Day is celebrated in India every year on February 28th. It commemorates the day in 1928 when the Indian physicist Sir C.V. Raman discovered the "Raman Effect," a breakthrough in the field of light scattering that earned him the Nobel Prize in Physics in 1930.
Today, the day serves as a national festival of science to promote scientific temper, recognize the efforts of the scientific community, and inspire the next generation of innovators.
Theme 2026: "Science and Technology for a Sustainable Future"
The theme for National Science Day 2026 is "Science and Technology for a Sustainable Future." Building on the previous year's focus on youth leadership, the 2026 theme emphasizes that scientific innovation is our most powerful tool for survival and growth in a changing world. The campaign is structured around four critical areas:
1. Climate Resilience and Green Tech
A major focus is on developing "Indigenous Technologies" (Home-grown tech) to combat climate change. This includes breakthroughs in:
-
Green Hydrogen: Making India a global hub for clean energy.
-
Smart Agriculture: Using AI and satellite data to help farmers adapt to unpredictable weather patterns.
2. The "Viksit Bharat" 2047 Vision
As India marches toward becoming a developed nation by 2047, the 2026 theme highlights the role of science in economic sovereignty. It focuses on reducing dependence on imports by innovating in critical sectors like semiconductors, space exploration, and deep-sea mining.
3. Women in STEM (Science, Technology, Engineering, Mathematics)
The 2026 observance places a heavy emphasis on "Gender Parity in the Lab." Programs like WISE-KIRAN (Women in Science and Engineering) are spotlighted to encourage more girls to pursue high-level research careers, recognizing that a sustainable future requires 100% of the nation's talent.
4. Scientific Temper vs. Misinformation
In the age of AI and social media, the theme promotes "Critical Thinking." The government and educational bodies use this day to teach citizens how to verify facts, use evidence-based reasoning, and reject superstitions.
The Discovery: What is the Raman Effect?
In simple terms, the Raman Effect is the change in the wavelength of light that occurs when a light beam is deflected by molecules.
When you shine a light through a transparent medium (like water or a crystal), most of the light passes through unchanged. However, a tiny fraction of that light "scatters" and changes color. This color change tells scientists exactly what kind of molecules are inside that substance.
Fun Fact: C.V. Raman was inspired to study this after he was mesmerized by the deep blue color of the Mediterranean Sea while traveling to London by ship. He realized the sea's color wasn't just a reflection of the sky—the water molecules themselves were scattering the light!
