"Scientific Issues for Development of the Nation"

NATIONAL SCIENCE DAY 28 FEB.2016

1. Sir Chandrasekhara Venkata Raman was awarded the Nobel Prize in Physics in 1930 for his ground-breaking achievement of the Raman effect in 1928.

2. The Raman effect was discovered during Raman's tenure at the Indian Association for the Cultivation of Science, Kolkata from 1907 to 1933.

3. The Raman effect is defined as "a change of wavelength exhibited by some of the radiation scattered in a medium."

4. In other words, Raman discovered that when light passes through a transparent medium, some of the deflected light changes its wavelength.

5. This phenomenon came to be known as Raman scattering, from which results the Raman effect.

6. In 1986, The National Council for Science and Technology Communication (NCSTC) had urged the Indian government to declare February 28 as National Science Day.

7. Every year the day is assigned a theme. For 2016, the theme is "Scientific Issues for Development of the Nation".

8. In 1954, Sir C V Raman was awarded the highest civilian honour, the Bharat Ratna.
