Source: Based on Ganitapāda verses 19–24 of Aryabhata’s Aryabhatiya
SummaryIn Episode 16, Harsh Rain unlocks Aryabhata’s 499 CE mastery of numbers, following his shadow triumphs in Episode 15. From a merchant tallying 325 saffron sacks with arithmetic sequences (Verse 19) to builders stacking triangular (n(n+1)/2) and tetrahedral (n(n+1)(n+2)/6) piles (Verse 20), Aryabhata’s formulas shaped trade and architecture. Squares (n(n+1)(2n+1)/6) and cubes ([n(n+1)/2]²) fueled star-tracking (Verse 22), while geometric riddles—like a king’s 100-coin puzzle (Verse 21) or a trader’s 50-coin gems (Verse 23)—revealed hidden values. This ancient code, chanted in Sanskrit, wove order into chaos, bridging Pataliputra’s markets to the cosmos.
