Against the backdrop of India’s rich heritage and traditions, the day exists to highlight the country’s scientific prowess and ingenuity. Every February 28, the nation honors the remarkable achievements of scientists, recognizing their vital role in advancing progress and innovation.
But what is so special about this day and why is it celebrated as National Science Day? Below you will find answers to such FAQs.
Why is National Science Day celebrated?
India observes February 28 every year as National Science Day to commemorate the important scientific milestone of CV Raman announcing the Raman effect on February 28, 1928. This discovery, which earned Raman the Nobel Prize in Physics in 1930, was the scientist’s unforgettable contribution to the country’s development.
What is Raman effect?
At the heart of the Science Day celebrations is the Raman effect, a phenomenon in which light scatters after interacting with matter, resulting in a change in the color of the emerging light.
For decades after Rayleigh scattering was discovered in 1871, it was widely believed that the ocean’s blue color was due solely to reflections from the sky. However, Sir CV Raman challenged this concept during a voyage from London in 1921. His curiosity led him to study molecular diffraction of light, and ultimately to the breakthrough discovery of the Raman effect.
Since then, the Raman effect has supported numerous scientific advances and facilitated the development of essential technologies to address countless global challenges. From detecting bombs and analyzing pills, powders, and liquids to studying cancerous tumor cells and minerals on distant planets, scientists have used this principle to tackle important questions across a variety of disciplines. I did.
What is the theme of National Science Day 2024?
The theme chosen for this year’s National Science Day celebrations is ‘Indigenous Technology for Vikshit Bharat’ (Indigenous Technology for a Developed India). This underlines the country’s commitment to promoting indigenous technological solutions for the well-being of society.
According to a statement from the Ministry of Science and Technology, the theme aims to raise public awareness of science, technology and innovation while highlighting the achievements of Indian scientists who leverage indigenous technology to address pressing challenges. The purpose is
By highlighting the importance of indigenous technologies, this year’s celebrations aim to stimulate collaboration and collaboration between the people and the scientific community, promoting India’s progress and contributing to global progress.
