Great Chinese Invention

Here is a explanation about one of China's greatest Inventions; The Compass

Before the compass was invented ships where frequently lost in the middle of the ocean. Then the Chinese invented the compass and that solved the problem.

It's not possible to tell who actually invented the first compass. But the compass was used around the Qin Dynasty (221-206 BC).

Compasses are navigational tools that allow hikers and explorers to find their way in the wilderness by pointing the way to magnetic north. Compasses come in variety of different formats more expensive and more complicated compasses have advanced features. All compasses, however, have the same basic elements that make the devices to point the way to magnetic North.

A compass is important because it shows where North is. The compass can help hikers and explorers in the wilderness, help ships that are lost in the middle of the ocean and people who are lost in the wild or stranded on a island in the middle of nowhere, there are lots of different reasons where a compass can be used.

A compass points north because all magnets have to poles, a north pole and a South Pole, and the North Pole of one magnets is attracted to the south pole of another magnet. The Earth is a magnet that can connect with other magnets. The Earth's magnetic North Pole attracts the "north" ends of other magnets; it is technically the "South Pole" of our planet's magnetic field.

A compass is actually a navigational instrument that shows directions ina frame of reference that is relative to the surface of the Earth. A compass is a small magnet on a pivot.

The compass helps us with the navigational system. So when we are out lost in the middle of nowhere, but we have a compass we can find our way home. Another reason, you are ona cruise ship and the captain can't find his way back to the shore, but if you have a compass which can help him to help others find their way back to the shore. A compass helps lots of people including; explorers, hikers, ships, scuba divers, even famous people use the compass if they are lost in the wilderness.

In Conclusion, a compass is a great invention for the use of travelling around the world. As long as you have a compass you are safe, that's only if you know how to use it. Soon you'll get the hang of it.
