National Science Day 2026: Check Theme, slogans, speech ideas, The Raman Effect and everything you need to know

National Science Day is observed on February 28 every year across India to commemorate the discovery of the Raman Effect by eminent Indian physicist C. V. Raman in 1928. The Department of Science and Technology (DST), Government of India, has announced the theme for National Science Day 2026 as “Women in Science: Catalyzing Viksit Bharat.”

National Science Day is observed annually to celebrate the discovery of the Raman Effect by physicist CV Raman in 1928, a breakthrough that earned him the Nobel Prize and placed Indian science on the global map.

National Science Day 2026 Theme

The Government of India, through the Ministry of Science and Technology's Department of Science and Technology (DST), will host the national-level celebration at Vigyan Bhawan in New Delhi under the theme: "Women in Science: Catalyzing Viksit Bharat." The theme aligns scientific advancement with India's vision of becoming a developed nation while recognising the role of women researchers and innovators.

What is the Raman effect?

National Science Day is celebrated to commemorate Sir C. V. Raman’s groundbreaking discovery of the scattering of light, famously known as the Raman Effect, which he announced on February 28, 1928. This remarkable achievement later earned him the Nobel Prize in Physics in 1930, making him the first Asian scientist to receive the prestigious award in the field of science.

The day highlights the immense value of fundamental research and its lasting influence on technological and industrial advancement. Raman’s discovery demonstrated how light changes its properties when it passes through a transparent material, helping scientists understand the molecular structure of substances and opening new paths for scientific exploration.
