- compass:
The compass was invented in China. As early as in the Warring States Period (450 B.C.-221 B.C.), a magnet was used as a device that pointed to magnetic north, and this device was named “Si Nan” by the ancient Chinese. In the Northern Song Dynasty (960 A.D.-1127 A.D.), another device was invented with a magnetic iron needle that pointed to magnetic north, and this device was later used in navigation. The compass was introduced to Europe in the 13th century.
中国首先发明指南针。 战国时期,中国已经用磁石制成了指南的仪器,古人称它为“司南”。 北宋时,又发明了用天然磁石摩擦钢针制成的罗盘针,即真正的指南针,并应用于航海。 13世纪指南针传到欧洲。
