在指南针发明之前 人类辨别方向主要靠太阳,月亮等天体,或者山石树木等标志物,然而,这些辨别方向的手段都有其局限性:靠天体辨别方向 在恶劣的天气环境下就无法实现,比如雨天,雾天,阴天.而靠标志物辨别方向 只能局限于小的范围内.
后来 人们发现磁石的南北极特性而发明了指南针.从而可以在任何环境下准确的辨别方向.
指南针最大的贡献是促进了航海的发展,海上运输的发达以及发现新大陆等指南针都功不可没.

The mankind take the bearings to mainly depend the sun before the mariner's compass invent,moon etc.heavenly body,perhaps mountain stone tree etc.marking thing,however,these meanses for taking the bearings all has it to limit sex:is taken the bearings by heavenly body under the bad weather environment and then can't carry out,for example rainy day,fog day,cloudy day.But depend marking a thing to take the bearings can limit at inside small scope.
Afterwards people discover the south North Pole characteristic of loadstone but invented mariner's compass.Can take the bearings accurately under any environment thus.
Mariner's compass the biggest contribution is to promote maritime development,transport at the sea of flourishing and discover New Continent etc.the mariner's compasses all perform feats

Before compass invention the humanity takes one's bearings mainlydepends on the sun, heavenly body and so on the moon, or sign and soon mountain stone trees, however, these take one's bearings the methodall has its limitation: Depends on the heavenly body to take one'sbearings under the bad weather environment is unable to realize, forinstance rainy day, foggy day, cloudy day But depends on the sign totake one's bearings only can limit in the small scope
Afterwards the people discovered the magnet the south North Polecharacteristic has invented the compass Thus may accurate take one'sbearings under any environment
The compass biggest contribution promoted the navigation development,the sea transportation the new continent compass and so on wasdeveloped as well as discovered all had lasting achievements

before the invention of the compass, people decided the directions mainly by the sun, the moon, and other asteral bodies, or landmarks such as mountains, stones, and trees. but, these methods has their restrictions:you cannot depend on a asteral body when the weather is bad, for instance, during rain, fog,and overcast days. while using landmarks only work within a small area.
Later, people discovered the polarity of magnets and invented the compass and can now determine directions under any circunstances. the compass's greatest contribution is that it promoted marine development, transportation by sea and the discovery of new continents are all achievements of the compass.
