The Seismoscope: A Revolutionary Invention
Let’s delve into the remarkable legacy of Zhang Heng, particularly focusing on his groundbreaking invention: the **seismoscope**. Picture a sophisticated device capable of detecting earthquakes long before the advent of contemporary technology. This is precisely what Zhang Heng accomplished with his innovative creation!
### Design and Functionality
The seismoscope was ingeniously designed as a cylindrical apparatus embellished with eight dragon heads, each one clutching a ball in its mouth. Beneath each dragon, there was a frog positioned to catch the ball if it were to fall. This clever design allowed the device to indicate the direction from which an earthquake originated. When an earthquake struck, a ball would drop from the mouth of one of the dragon heads, effectively signaling the occurrence of the seismic event. It resembled a game of catch, but with a significant and serious purpose behind it!
### How It Worked
