The National Council for Science and Technology Communication approached the Center in 1986 to designate February 28 as National Science Day.
India will celebrate National Science Day on Monday, February 28 – the day scientist CV Raman invented his breakthrough Raman effect in 1928. Raman won the Nobel Prize in Physics for his landmark discovery in 1930.
The National Council for Science and Technology Communication approached the Center in 1986 to designate February 28 as National Science Day. The government accepted the proposal and the first National Science Day was celebrated on February 28, 1987.
The aim of National Science Day is to encourage young Indians to take an interest in science and understand its importance. On this day, students from all over the country present scientific projects and innovations in national and national competitions.
The Center also commends scientists who have contributed to the field of science.
2022 NATIONAL SCIENCE DAY THEME
This year, National Science Day 2022 will be themed “An Integrated Approach to Science and Technology for a Sustainable Future”.
Raman scattering or Raman effect is a phenomenon of spectroscopy discovered by Raman while working at the laboratory of Indian Association for Culture of Science in Kolkata. The Raman effect describes how the wavelength of light scatters when it is deflected onto a particular object.
Raman first observed the phenomenon in 1921 while traveling in Europe. Noticing the blue color of the Mediterranean Sea and the icebergs, he wanted to understand the reason for this striking phenomenon. He began experimenting with transparent blocks of ice and light from a mercury arc lamp. He recorded the change in wavelength after shining the light through ice cubes.
Although not the first person to observe the phenomenon, Raman was the first to publish the observations in 1928. Russian physicists Grigory Landsberg and Leonid Mandelstam first observed the effect just a week before Raman. However, they released their results months after Raman.
This was an important discovery that paved the way for several future scientific developments. National Science Day honors the iconic physicist and calls on India’s youth to follow in his footsteps.
