Why this matters now
Ancient science and its scholars are prelims favourites and a recurring source of pride in S&T and culture answers.
Mathematics and astronomy
India gave the world the concept of zero and the decimal place-value system. Aryabhata (the Aryabhatiya) worked on the value of pi, trigonometry and the rotation of the Earth; Brahmagupta formalised rules for zero and negative numbers; Varahamihira (astronomy/Brihat Samhita) and Bhaskara II (Lilavati) advanced mathematics and astronomy.
Medicine
Indian medicine (Ayurveda) is among the oldest systems: Charaka (the Charaka Samhita — medicine) and Sushruta (the Sushruta Samhita — surgery, the “father of surgery”) made pioneering contributions. Yoga (Patanjali) is part of this heritage.
Metallurgy and technology
India excelled in metallurgy — the rust-resistant Mehrauli Iron Pillar (Delhi) testifies to advanced iron technology; wootz steel was prized worldwide. Achievements also spanned shipbuilding, textiles, architecture and town planning (from the Indus Valley onwards).
UPSC angle
Know contributions — zero & decimal system, Aryabhata (pi/rotation), Brahmagupta (zero rules), Bhaskara II (Lilavati), Charaka (medicine)/Sushruta (surgery), Ayurveda, and the rust-free Iron Pillar/wootz steel.
