The Han Dynasty is considered a golden age in Chinese history, especially in art, politics, and technology. Let us know about some of the great discoveries made by the Han Dynasty in this article.

1. Seismograph:-

Chinese scientist Zhang Heng worked from astronomy to watchmaking, but he is best known for making the first instrument to detect distant earthquakes. Zhang Heng introduced this device to Han's court in 132 A.D. 

Seismograph-INVENTION

This device was simple an urn equipped with a pendulum. Whenever this dragon type instrument feels an earth vibration, it used to drop a ball from the mouth of a metal dragon into a metal frog, creating a loud clang that cautions the occurrence of an earthquake somewhere in the country.

2. Suspension Bridge:-

According to Robert Temple, the Genius artisans of the Han Dynasty carried out the development of the suspension bridge. This was a flat roadway suspended from cables, which probably evolved from simple rope bridges made to cover small gorges.

The suspension bridge developed around 90 A.D and later on became more sophisticated structures with wooden planks.

Such a suspension bridge is still built in the northeastern states of India with ropes and roots of plants.

3. The invention of Paper:-

Cai Lun, a eunuch in the Han court in 105 A.D., is credited to be the inventor of the first high-quality writing paper.

The earliest scrap of paper still exists, this scrap was found in 1957 in a tomb found in China. Investigation revealed that this scrap was dated to 140 and 87 BC. 

Cai Lun used hemp, linen rags, crushing and combining tree bark and scraps from fishing nets and then treating the mixture with lye to break it down into finer fibers.
