Introduction
"It is science alone that can solve the problems of hunger and poverty,
of insanitation and malnutrition, of illiteracy and obscurantism of superstition
and deadening customs, rigid traditions, and blind beliefs, of vast resources
going to waste of a rich country inhabited by starving millions." These words
of India's first Prime Minister Jawaharlal Nehru, while delivering the
convocation address of Allahabad University in 1946, indicates the importance
of science in human life.
