1) Advances in mathematics and astronomy — e.g., Aryabhata (c. 5th century) wrote the Aryabhatiya, used the decimal place‑value system with zero as a placeholder, gave an accurate approximation of π (≈3.1416), produced sine tables, and proposed that the earth rotates on its axis to explain day/night. These ideas greatly advanced calculation, trigonometry, and astronomical models.
2) Metallurgy — exemplified by the Iron Pillar of Delhi (erected in the Gupta period). The pillar’s high‑purity, rust‑resistant iron and advanced forging techniques show sophisticated knowledge of iron smelting, alloying and corrosion resistance long before similar European technologies.
