The celebration of National Science Day consists of public speeches, science movies, science exhibitions, events based on science themes, concepts, and many more activities
Each year, February 28 is celebrated as National Science Day to commemorate the discovery of the ‘Raman Effect’ by Indian physicist CV Raman. This year, the theme of the celebrations is ‘Integrated Approach in Science and Technology for Sustainable Future’
The government of India felicitates scientists who have contributed immensely in the field of science to mark the anniversary of India's greatest discovery- the 'Raman effect.
The Raman Effect is a change in the wavelength of light that occurs when a light beam is deflected by molecules.
Raman had a great fascination with gemstones and he loved to study the optical characters of opals, moonstones, agates, rubies and diamonds in his laboratory.For his study and research, C V Raman needed a large piece of diamond and he came to know that one such piece was in the possession of the Maharaja of Darbhanga, Rameshwar Singh. He immediately contacted the Maharaja who generously lent him two pieces of diamond. One was a 20-carat colourless and flawless stone. The other was an extraordinary gem of 140 carats-clear, pale yellow and about 3 cm in linear dimension. This diamond was supposedly the ‘Peshwa Diamond’, a diamond originally owned by Peshwa Bajirao and which Maharaja wore as a ring on his finger.
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 that of the incident (incoming) beam.
Most of this scattered light is of unchanged wavelength. A small part, however, has wavelengths different from that of the incident light; its presence is a result of the Raman effect.

- Humankind has the science and technology to destroy itself or to provide prosperity for all. But while science offers us these opportunities, science will not make that choice for us. Only the moral power of a world acting as a community can-Margaret Beckett.

Prime Minister Narendra Modi on Monday greeted scientists and science enthusiasts on the occasion of National Science Day and called for reaffirming commitment towards leveraging the power of science for human progress. This day commemorates the discovery of the 'Raman effect', for which Indian physicist C V Raman won the Nobel Prize.
Modi tweeted, "National Science Day greetings to all scientists and science enthusiasts. Let us reaffirm our commitment towards fulfilling our collective scientific responsibility and leveraging the power of science for human progress."
He had urged families to make efforts to develop a scientific temperament in their children.
