The Han Invented the Seismoscope? Zhang Heng's Bronze Machine
Om avsnittet
In 132 AD, Zhang Heng, a polymath of the Han court, presented Emperor Shun with a bronze device that could detect an earthquake hundreds of miles away. It was the world's first seismoscope, and its workings were so precise that when it first alerted officials to a tremor, no one in Luoyang felt a thing — until a messenger arrived from Longxi days later. In this special 200th episode of Fexingo History, Lucas and Luna explore the life of Zhang Heng, the man who also mapped the heavens, built an armillary sphere, and calculated pi. They unpick the mechanics of the seismometer, its eight dragons and bronze toads, and the controversy over whether it actually worked as described. They also touch on the Han dynasty's scientific culture, the imperial observatory, and the fate of Zhang's inventions after his death. It's a story of bronze, earthquake, and the quiet genius of a court bureaucrat who looked to the skies and the shaking earth.
