National Science Day is celebrated every year on 28 February. It is an important milestone in the field of Indian science and research. The day is dedicated to Indian scientist Sir Chandrashekhar Venkataraman’s great discovery, Raman effect. The aim of this day is to spread awareness about science and promote scientific outlook in society. Since 1986, this day is celebrated as National Science Day all over India.
