The World's First Automatic Crossbow- The Chu-Ko-Nu

Rare Folio on Instagram: "The post's animation depicts two points on a circle rotating with angles based on 100 × 3.14 radians, forming a closed star-like path that symbolises inevitable reunion, contrasting the infinite, non-repeating nature of true π. Mathematically, using the rational approximation 3.14/π leads to periodic orbits that close exactly after finite steps, unlike irrational π which produces dense fillings of the circle, a concept rooted in ergodic theory and proven by Lambert's 17
