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.

National Science Day
This year’s National Science Day, celebrated to commemorate the discovery of Dr. C V Raman’s ‘Raman Effect’, is themed around ‘Science and Technology for Specially Abled Persons’. One billion people, or 15% of the world’s population, experience some form of disability today, and the prevalence of disability is highest in developing countries like India. A report by World Bank estimates that about 110-190 million of them experience significant disabilities. ‘Persons with disabilities’ or PwDs include those who have long-term physical, mental, intellectual or sensory impairments which may hinder their full and effective participation in the society.
ISRO hit a century of sorts with its launch of 104 satellites in one go. This has been a world record and everyone is proud of ISRO for what it has achieved. Have you wondered what enabled this scientific and technological achievement? Much of the ground work happened at Indian Institute of Science in primarily three scientific and engineering departments - aerospace, materials and electrical communication engineering. Aerospace Engineering helped in building and launching the satellites. Materials Engineering, then Metallurgy helped in arriving at the right composites, alloys and materials for the outer cover for launch vehicles and satellites that helped them to weather extreme conditions. The Electrical Communication Engineering Department helped with the technology to control and communicate with the satellites. It is interesting to note that all three were established during 1940s and before India became independent in 1947. In many ways from the science and technology to building capacity, IISc has been playing a key role.
