India’s great scientist Sir CV Raman emerged as the first Nobel Prize winner in Physics from across the Asian continent. He discovered the Raman effect on 28 February 1928 which is now celebrated as the National Science Day. The entire nation expresses gratitude to Sir CV Raman and to all the scientists on this day for their discoveries and inventions.

Raman was born on 8 November 1888 in Madras. He was a bright student and started his career with Financial Civil Services as an Assistant Accountant- General in Kolkata. Later on, he also started to work with Indian Association for the Cultivation of Science in his spare time in the field of acoustics. He worked on his own for next 10 years and established himself as a scientist not just in India but also in Europe. In 1917, Raman was appointed as the lecturer in Kolkata University.

During his tenure, he did a lot of experiments and also published a note on “The colour of the sea”. Before Raman introduced his theory, it was believed that the sea gets its blue colour from the sky or due to the suspended matter in the water. But, Raman denied this theory and figured out that the blue colour of the sea was obtained from the molecular diffraction. Then he came up with an experiment on the scattering of light which led to further developments and hence Raman effect was discovered.

Later, 28 February was declared as the National Science Day which was wholly dedicated to science. All the schools and science colleges organise events related to science on this particular day and are also inspired to work in the field of science and technology.
