For a long time Indian histroians were engaged in political, economic and cultural history. In the western circles. India was dismissed as "a spiritual but poor country". The western world boasted of their material development. During colonial rule the British authorities wanted India to be a supplier of raw materials and market for their manufactured goods. Therefore scientific and technical education was discouraged to arrest Indian material development, so that India would not be able to stage an Industrial Revolution. This book in its collection of thirteen learned essays explores the scientific and technological heritage of India during colonial days.
