Celebrate National Science Day 2023: Here is What You Need to Know!
28-02-2023 10:48
National Science Day is celebrated in India on 28 February annually. This day is celebrated to mark the discovery of the Raman Effect by the genius scientist Sir C.V. Raman in 1928. Raman Effect is the 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.
The day is celebrated throughout the country by organizing various science-related activities.
Theme of National Science Day, 2023
The theme for National Science Day, 2023 is Global Science for Global Wellbeing. It is marked to raise awareness about the importance of science in the day-to-day lives of people and to celebrate the spirit of science and the incredible discoveries and inventions made by our scientists and researchers in the field of technology that help humankind.
Facts about Sir C.V. Raman that you must know
Son of a Mathematics and Physics lecturer, Chandrasekhara Venkata Raman was born in Tiruchirappalli, Tamil Nadu on 7th November 1888.
Raman was a very bright and intelligent student. In 1902, when he was just 14, got admitted to Presidency College, Madras, and in 1904, he won a gold medal in Physics. In 1907, he gained his M.A. degree with the highest distinction.
Sir C.V. Raman has started his research on optics and acoustics - the two fields of investigation to which he has dedicated his entire career.
Due to his father, Raman joined the Indian Finance Department in 1907. Though the job was very hectic, he managed to continue his research work at night. Sir C.V. Raman did his research in the laboratory of the Indian Association for the Cultivation of Science at Calcutta (of which he became Honorary Secretary in 1919).
He became a Professor at the Indian Institute of Science at Bangalore (1933 - 1948) and since 1948 he is the director of the Raman Institute of Research at Bangalore, established by himself.
He also founded and became the editor of the Indian Journal of Physics in 1926.
C.V. Raman discovered the non-linear scattering of photons which is named as Raman Effect or Raman Scattering.
In 1922, he published his work on the “Molecular Diffraction of Light”, which gained him the 1930 Nobel Prize in Physics. He became the first Indian to receive the Nobel Prize in Physics.
