National Science Day is celebrated in India every year on February 28 to mark the discovery of the 'Raman effect' by Indian physicist Sir C. V. Raman for his discovery. The government of India thus designated the day as National Science Day in 1986. C.V Raman was awarded a Nobel Prize in Physics in 1930 for the discovery of the Raman Effect.
Raman effect is the inelastic scattering of photons by matter, which means that there is an exchange of energy and a change in the light's direction. Of the 607 Nobel medals awarded so far in scientific disciplines globally, just 20 have gone to women.
