The Song Dynasty: Innovation Before the Modern World — Fexingo History
In this episode, Lucas and Luna return to the towering figure of Su Song—the Song dynasty polymath who built a 12-meter astronomical clock tower in Kaifeng around 1090. They explore how Su Song's Xin Yi Xiang Fa Yao (New Design for an Armillary Clock) described an escapement mechanism and a chain drive centuries before they appeared in Europe. The conversation touches on the clock's water-wheel power, its rotating armillary sphere and celestial globe, and the bureaucratic and technical challenges Su Song faced. They also consider why this engineering marvel was dismantled by the Jin invaders and why its principles were not revived for centuries. Along the way, they connect Su Song's work to earlier Song innovations in timekeeping and astronomy, and reflect on what the loss of such knowledge means for our understanding of medieval Chinese science. #SuSong #SongDynasty #CosmicClock #XinYiXiangFaYao #Kaifeng #Astronomy #HistoryOfScience #Escapement #ChainDrive #ArmillarySphere #CelestialGlobe #WaterClock #BencaoTujing #SongZhezong #ChineseInvention #MedievalChina #History #FexingoHistory Keep every episode free: buymeacoffee.com/fexingo [https://buymeacoffee.com/fexingo]
