A Tool That Changed Navigation
One of China’s greatest inventions was the compass. It helped sailors and travelers find their way and changed world history. The first compasses were made more than 2,000 years ago, during the Han Dynasty. They were not used for ships at first but for telling directions in building and fortune-telling.
The compass worked with a stone called lodestone, which naturally points north. Later, Chinese inventors discovered that they could make iron magnetic by rubbing it with lodestone. They placed the magnetic needle on water or inside a box so it could turn freely. The needle always pointed north-south.
By the Song Dynasty, around the 11th century, sailors used compasses to guide ships on the sea. Before this, people traveled by watching the stars or the sun. But in bad weather or on cloudy nights, this was difficult. The compass gave sailors a safe and reliable tool to travel farther than ever before.
The compass traveled along trade routes to the Middle East and Europe. There, it helped explorers like Christopher Columbus and Vasco da Gama. Without the compass, the Age of Exploration might never have happened. This Chinese invention truly connected the world.
Today, compasses are still used in hiking, camping, and the military, even though we now also use GPS. The story of the compass reminds us that one small tool can change the course of human history.
