Invented (發(fā)明) it. Zhang Heng was born in Nanyang in the Eastern Han dynasty.At that time,earthquakes (地震) happened every year.People thought they were from ghosts,but Zhang Heng didn't believe that.He studied about earthquakes for many years,and in AD 132 he invented the first seismometer (地動(dòng)儀) in the world. | |
Used it. At first,people didn't believe it.In December,AD 134,Zhang Heng's seismometer told that there would be an earthquake in the west of the country.After four days,three earthquakes really happened there.People believed that it was helpful from then on.But the seismometer was lost later. | |
Reproduced it. Scientists tried to reproduce a seismometer like Zhang Heng's in the past years.Now there is a reproduced one in Shanghai museum.Some people say it was a little helpful during the earthquakes in Tangshan.We hope it will be better soon and be really able to help people one day. |
