10 Famous Things That Were Invented Way Earlier Than You Think

8. The Seismoscope: Ancient China's Earthquake Detector

The seismoscope, invented by the Chinese polymath Zhang Heng in 132 AD, was an early device for detecting earthquakes. This ingenious invention consisted of a large bronze vessel with eight dragon-shaped tubes, each holding a small ball. When an earthquake occurred, the vibrations would cause a ball to drop from the mouth of one of the dragons, indicating the direction of the seismic activity. The seismoscope demonstrated a sophisticated understanding of seismic phenomena and provided a means of detecting earthquakes long before modern seismology was developed. Zhang Heng's invention highlights the advanced scientific knowledge of ancient China and their ability to create practical solutions to natural challenges. The seismoscope serves as a testament to the enduring human quest to understand and mitigate the forces of nature. By exploring the history of this remarkable device, we gain a deeper appreciation for the innovative spirit that has driven scientific discovery throughout the ages.
