Celebrating 84 Years of 'Raman Effect'

India celebrated 84 years of ‘Raman Effect’ yesterday on 28th February to mark the achievement by Nobel laureate CV Raman. Seminars, lectures and symposiums were organized reportedly in Lucknow to commemorate this National Science Day.

Raman scattering or the Raman Effect is named after the great scientist of India, CV Raman, who first propounded the theory. It is the inelastic scattering of a photon. It was discovered by Raman and K S Krishnan in liquids and by Grigory Landsberg and Leonid Mandelstam in crystals. He eventually got the Nobel Prize for this.

In 1922, Raman published his work on the "Molecular Diffraction of Light," the first of a series of investigations with his collaborators that at last led to his discovery of the radiation effect on 28 February 1928 which is called ‘Raman Effect’.

Celebrating the occasion at the Regional Science City, BN Dhawan, former director, Central Drug Research Institute (CDRI) presented an excellent speech. He wanted the students to follow the footsteps of the ancient Indian eminent scientists like Aryabhatta, Ramanujam, Sushrut and Charak.

He commended the legendary inventions and discoveries of these great scientists with the limited resources and scopes available then.

In Amity University the event was also celebrated to promote the scientific and innovative abilities of the students and teachers. 'Clean energy options and nuclear safety' was this year’s topic to be focused.

On this occasion, Prof Kripa Shankar presented his speech on renewable energy and energy efficiency and another learned Professor P K Seth orated on India’s prospect in Biotechnology.
