India’s National Science Day and the Researcher Behind the Raman Effect

Last updated: October 13, 2026

Every February 28, India runs science fairs, school exhibitions, and award ceremonies to mark National Science Day. The date commemorates a single 1928 experiment in Calcutta that earned a Nobel Prize and gave the country something to celebrate each year. According to a Firstpost feature on the day, 2022's theme — "Integrated Access at S&T for a Sustainable Future" — sits on top of a much older and more interesting story about the man whose discovery started the tradition.

At a glance:

• National Science Day is observed in India on February 28 each year.
• The date marks the 1928 discovery of the Raman Effect by physicist CV Raman.
• Raman received the Nobel Prize in Physics in 1930.
• The 2022 theme was "Integrated Access at S&T for a Sustainable Future."
• The first National Science Day was held on February 28, 1987, after the National Council for Science and Technology Communication proposed the date to the government in 1986.

Who CV Raman was

According to the Firstpost piece, Chandrasekhara Venkata Raman was born on November 7, 1888, in Tamil Nadu. His father, a mathematics and physics lecturer, pushed him toward science early. By 11, he was already at college. He earned his bachelor's in 1904 with a first-rank gold medal in physics, completed a master's, and — in a bit that ages well — turned down a colonial government finance job to stay in science. He became the first Palit Professor of Physics at the University of Calcutta in 1917 and ran research on the side at the Indian Association for the Cultivation of Science.

The Raman Effect, in one paragraph

While experimenting with light scattering at IACS in 1928, Raman observed a shift in wavelength that occurred when a beam of light was deflected by molecules. The phenomenon — where scattered light changes frequency depending on what it bounces off — was named the Raman Effect. It became a workhorse technique in spectroscopy and material analysis. Two years later, the Nobel committee agreed it was a big deal.

How the day became a national fixture

The National Council for Science and Technology Communication proposed February 28 as National Science Day in 1986. The government accepted, and the country observed the first one in 1987, according to Firstpost. Schools, colleges, and research institutes now run exhibitions and demonstrations every year. The government also uses the day to honor Indian scientists with national awards.

Why it matters, briefly

The Raman Effect is not a historical curiosity. Raman-based spectroscopy is still used in chemistry labs, pharmaceuticals, forensics, and materials science to identify molecular fingerprints without destroying the sample. So every February 28 has a working scientific reason attached to it, not just a ceremonial one.

Say you teach high school chemistry

Say you teach high school chemistry and want a hook for a spectroscopy unit. The Raman Effect is a good one — it is the kind of experiment a decent undergraduate lab can replicate with a laser, a cuvette, and a spectrometer. Tying it back to National Science Day gives students a concrete reason to remember the date and the physicist.

What to watch next

The theme changes each year. The 2021 theme — "The Future of STI" — and the 2022 theme on integrated sustainable access suggest a slow pivot toward science-policy framing. Worth keeping an eye on whether subsequent themes lean harder into sustainability or back into pure research recognition.

Key takeaways

• February 28 marks the 1928 discovery, not Raman's birthday.
• Raman won the Nobel two years after the discovery, in 1930.
• The Indian government formalized National Science Day starting in 1987.
