A crow (乌鸦) wants to drink, but he can't find water. He looks here and there. At last, he cries, "I can see a jar (罐子) and there is some water in it." He tries to get the water, but he can't. "How can I get the water?" he cries, "I can put my break (鸟嘴) quite close it." But still he cannot drink. "What can I do? I want to drink." He looks here and there, then he picks up a small stone (石头) in his break and carries it to the jar of water and drops it into the jar. "Soon the water will be high in the jar, and I can drink," says the crow. So he begins to do that until the water is high (高的) enough to drink.
Zhang Heng was a famous scientist in the history of China. His invention Hou Feng Seismometer was a great success and it helped us understand the world better.
(AD 78-139) | It was invented. Zhang Heng was born in Nanyang in the eastern Han Dynasty. At that time, there were many earthquakes every year. People thought they were from ghosts. Zhang Heng, however, didn't believe it. He tried to find ways to study earthquakes for many years and in 132 he invented the first seismometer in the world. |
It was used. But at first, people didn't believe it and all laughed at him. In February, 138, Zhang heng's seismometer told there was an earthquake in the west of Luoyang. After four days, three earthquakes really happened in Luoyang area. It was believed to be useful from then on. However, it was lost 1700 years ago. | |
It was reproduced(再生产). Scientists have been trying to reproduce one like that. In 2012, the latest reproduced seismometer was successfully listed in Shanghai museum. It was reported to have been a little helpful during the earthquakes in Tangshan, Yunnan and Sichuan. It is hoped to be improved better soon and be able to predict coming earthquakes one day. |
