The compass is a device that shows which direction you are going using a magnet and needle.
The compass is essential for sailing in cloudy skies or in winter to safely get to your destination without having to guess were to go. The compass is very useful when adventuring too. If you are exploring, bring a compass, because it will help you find your way around.
Before the compass, Polynesians used stars and waves to see where they were going. The Europeans used stars, landmarks and familiar winds to navigate where to go, but sailing on the open-ocean would be challenging without a compass. It would be practically impossible in winter. The Chinese believed in Chi. Chi was a life force that flowed through the body. And finding due North would maximize Chi. The compass was invented in China during the Han Dynasty between the 2nd century BC and 1st century AD, where it was called the “south-governor”.
The main difference between the way Europeans and Chinese used the compass is that the Europeans used the compass is to sail and go around the earth and the Chinese used the compass to maximize their Chi.
