What is the significance of the odometer in ancient Chinese technology?
-The odometer, or rangefinder chariot, was an ancient device used to measure distances, similar to modern odometers in vehicles. It used a reduction gear train to signal the passing of every 500 yards with the banging of a drum, demonstrating an early understanding of gear systems and mechanical engineering.
What evidence suggests that the Chinese had a tradition of ingenious geared machines?
-The discovery of beautifully engraved jade rings from tombs dating back to 400 BC suggests the use of compound machines to create precision spiral designs. These machines synchronized rotational with linear motion, indicating a high level of mechanical sophistication.
How did the Terracotta Army demonstrate the capabilities of ancient Chinese engineers and craftsmen?
-The Terracotta Army, consisting of over 8,000 individually sculpted, cast, and polished warrior statues, each armed with fully functioning bronze weapons, demonstrated the ability to mass produce high-quality items on an enormous scale, showcasing the advanced production techniques of ancient China.
What was Su Song's most notable invention, and how did it reflect the technological expertise of ancient China?
-Su Song's most notable invention was the cosmic engine, a water-controlled astronomical computer that calculated time and the movements of the Earth and planets through space. It was a monumental feat of engineering and science, reflecting the advanced technological expertise of ancient China.
