Ancient Indian Science and Technology
What the topic is and why it matters for UPSC
The chapter “Ancient Indian Science and Technology” traces the evolution of scientific thought, engineering prowess, and technological innovations from the Harappan (Indus Valley) civilization through the Mauryan, Gupta, and early medieval periods. It showcases how Indian scholars pioneered mathematics, astronomy, metallurgy, medicine, and engineering long before similar breakthroughs in the West. For a civil‑service aspirant, this subject is a window into India’s indigenous knowledge systems, the cultural foundations of modern scientific temper, and the historical continuity that underpins contemporary policy debates on indigenous technology, heritage conservation, and science‑education reforms. Understanding these achievements also helps answer questions on India’s contribution to global civilization—a recurring theme in both prelims fact‑based queries and mains essay/discussion topics.
Constitutional / Legal foundation
The Constitution of India, under Article 48A (Fundamental Duty), enjoins every citizen to develop scientific temper, humanism and the spirit of inquiry and Article 51A(k) mandates the duty to protect and preserve the cultural heritage of the nation. These provisions underscore the relevance of ancient scientific heritage as a living legacy that the state must safeguard and promote.
