The theme for this year is 'Science and Technology for Specially-Abled Persons.' In essence, this year the thrust is on how to make the lives of the differently-abled better with the use of science and technology.

It is celebrated in honour of CV Raman, who discovered the Raman Effect — for which he was awarded the Nobel Prize in Physics in 1930. The phenomenon — which deals with how photons, or quantum measures of light, scatter when they are excited to a higher level — and its derivations and modifications are used to analyse solids, liquids and gases as well as their components.
