HRD Launches STARS scheme on National Science Day

The Union Human Resource Minister Prakash Javadekar launched the STARS scheme on National Science Day (28th February).

STAR Scheme

  • STARS is an acronym for Scheme for Translational and Advanced Research in Science to fund Science projects.
  • The scheme will be implemented at the cost of Rs 250 crores.
  • Under the scheme 500 science projects will be funded whose selection will be made based on competition.
  • IISC will be the coordinator of the scheme.

National Science Day: 28th February

The National Science Day is celebrated on 28th February every year in the memory of Indian physicist and a Nobel laureate Sir C.V. Raman. The National Day of Science is celebrated on 28th February to commemorate the discovery of Raman Effect for which he was awarded Nobel Prize in the year 1930. The theme of the 2019 National Science Day is Science for people and people for science.

Raman Effect

Raman Effect refers to the inelastic scattering of a photon by molecules which are excited to higher vibrational or rotational energy levels. Part of the light beam after passing through transparent medium gets scattered and the wavelength of these scattered rays is different from that of the incident rays of light. This phenomenon of scattering of light is termed as Raman Scattering and the cause of scattering is called the Raman Effect.

28 February: National Science Day

In India February 28 is celebrated as the National Science Day i.e. Rashtriya Vigyan Diwas (राष्ट्रीय विज्ञान दिवस) every year.

Significance of Day: It aims to impart scientific temper in the minds of people of all age groups.

The theme for year 2016 is “Scientific Issues for Development of the Nationthat aims at raising public appreciation.

This day is celebrated as science festival in the entire nation by organising science exhibitions, seminars, workshops, symposiums and many other activities.

Why National Science Day is celebrated?

  • This day marks the epoch-making discovery of Raman Effect by Indian physicist Chandrasekhara Venkata Raman (CV Raman) on February 28, 1928.
  • This discovery was awarded with the Nobel Prize in Physics in 1930.
  • In 2013, the American Chemical Society designated the ‘Raman Effect’ as an International Historic Chemical Landmark.

Background

In 1986, National Council for Science and Technology Communication (NCSTC) had demanded Union Government to assign February 28 as the ‘National Science Day’ for India. The first National Science Day was celebrated on February 28, 2000.

The Raman Effect: Some part of light beam after passing through a transparent medium gets scattered. This phenomenon of scattering of light is termed as Raman Scattering and the cause of scattering is called the Raman Effect. The wavelength of these scattered rays is different from that of the incident rays of light.
