National Science Day is celebrated in India on 28 February

National Science Day is celebrated every year on February 28 to commemorate the discovery of ‘Raman Effect’ by Indian physicist Sir C. V. Raman on 28 February 1928.

The National Council for Science and Technology Communication (NCSTC) proposed to the central government that National Science Day should be celebrated on February 28 every year to mark this discovery. After that, the Government of India accepted that proposal, and the first National Science Day was celebrated on February 28, 1987.

What is the Raman Effect?
The Raman Effect is a 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 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.

NATIONAL SCIENCE DAY QUOTES

• Science knows no country, because knowledge belongs to humanity, and is the torch that illuminates the world-Louis Pasteur
• The most beautiful thing we can experience is the mystery. It is the source of all true art and science-Albert Einstein
• Science without religion is lame, religion without science is blind-Albert Einstein
• An experiment is a question that science poses to Nature and a measurement is the recording of Nature’s answer-Max Planck
• One machine can do the work of fifty ordinary men. No machine can do the work of one extraordinary man-Elbert Hubbard
• 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.
