Answers
Although Atreya and Agnivesa dealt with the principles of Ayurveda in 800 BC, Charaka Samhita is credited with the first Ayurvedic compilation. He was the first physician to posit the concepts of digestion, metabolism and immunity. He studied the human body and offered various remedies for numerous diseases.
Science is a dynamic, expanding body of knowledge, covering new domains of experiences. It is a human endeavour to understand the world by building - up conceptual models on the basis of observations and thus arriving at theories, laws and principles. In a progressive society, science can play a truly liberating role, helping people escape from the vicious cycle of poverty, ignorance and superstition. People today are faced with an increasingly fast - changing world where the most important skills are flexibility, innovation and creativity. These different imperatives have to be kept in mind in shaping science education. Good science education is true to the child, true to life and true to the discipline.
