The 28th of February every year is celebrated across the country as ‘National Science Day’ to commemorate the discovery of ‘Raman effect’ by Sir C V Raman. About 90 years ago, Sir Chandrasekhara Venkata Raman, had a ‘eureka moment’ when he discovered how light scattered when it travelled in a transparent medium. After two years, this discovery won India her first Nobel Prize in Physics, for a work that was carried out entirely in India.
