You are now partially of a group of navigators that goes back hundreds of years. research dates the practice of the magnetize mineral lodestone as a compass all the way back to the year 1,000. ancient taiwanese explorers learned that they could float the stone on a little piece of forest in a cup of water and the stone would always point to the north pole. Sailors late discovered that rubbing a needle against a piece of lodestone made the needle charismatic and the evolution of the modern scope began, along with superstitions. Prior to the scientific explanation, sailors thought the grok was a charming object that could tell fortunes and cure illness. They besides thought that onions and garlic could block the magnetic force, so those ingredients never boarded their ships .
fortunately, we know that compasses today are useful tools that help us find our bearings – no magic trick required. Congratulations on joining the club of compass navigators !
