National Science Day 2025: Theme, Significance, Quotes And More

National Science Day 2025: National Science Day is observed annually in India on February 28 to commemorate the groundbreaking discovery of the scattering of photons by Indian scientist Chandrasekhara Venkata Raman in 1928. This phenomenon, later known as the "Raman Effect," earned Raman the Nobel Prize in Physics in 1930. On this day, educational institutions, research centres, and scientific organisations across the country host quiz competitions, seminars, and various events to celebrate scientific achievements.

What is the Raman Effect?

According to the website of the Ministry of Culture, the Raman Effect is a phenomenon in spectroscopy, which is defined as the scattering of photons by excited molecules at higher energy levels. In simple terms, it is the change in the wavelength of light that occurs when a light beam is deflected by molecules.

When a beam of light traverses a dust-free, transparent sample of a chemical compound, a small fraction of the light emerges in directions other than those of the incident (incoming) beam. Most of this scattered light is of an unchanged wavelength. A small part, however, has wavelengths different from those of the incident light; its presence is a result of the Raman Effect.

History of National Science Day

The National Council for Science and Technology Communication (NCSTC), in 1986, asked the Government of India to announce February 28 as National Science Day. The government accepted and declared the day as National Science Day. The first National Science Day was celebrated on February 28, 1987.

Theme for National Science Day 2025

The theme for National Science Day 2025 is "Empowering Indian Youth for Global Leadership in Science & Innovation for Viksit Bharat". The theme will focus on encouraging young minds, recognising groundbreaking contributions, and celebrating India's scientific achievements.

National Science Day 2025: Here are some of the inspirational quotes by CV Raman.

• The essence of science is independent thinking, hard work, and not equipment. When I got my Nobel Prize, I had spent hardly 200 rupees on my equipment.
• We must teach science in the mother tongue. Otherwise, science will become a highbrow activity. It will not be an activity in which all people can participate.
• It is not often that the idealism of student days finds adequate opportunity for expression in the later life of manhood.
