Once there was a young boy. He had no family except for an old llama. Each day the boy and his llama walked many miles, looking for a home. Each night they curled up (赌缩)and slept. But on one starry (满天星斗的)evening, the old llama died. The boy buried (埋葬)his friend next to a small icy river. Then he sat under a tree and cried. What would he do? He had no family and no home.
The boy cried for a very long time. But there was no one to comfort (安慰)him. There were only the stars in the sky.
Suddenly, the sky filled with bright light. The boy held his breath. He was afraid to move. One bright star fell to the ground. Slowly, the star took the shape of the old llama. She bent her head and drank from the river. She looked at the boy and smiled. As she jumped back into the sky, bits of llama wool fell. As the sun began to rise, the boy picked up the soft, warm wool. It gave out light in his hands like starlight. He carried the wool to the city and sold it. With the money, he bought a house. He bought two young llamas. He never forgot the star llama. And he was never lonely again.
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. |
