2. The Compass: Guiding Exploration and Technology
Ancient China’s invention of the magnetic compass in the Han Dynasty marked a turning point in world history. Initially used for feng shui and fortune-telling, the compass soon became essential for navigation, enabling sailors to traverse vast oceans and traders to map new routes. This pivotal device laid the groundwork for global exploration and cross-cultural exchange. Modern GPS systems are a technological descendant, continuing the tradition of helping humanity find its way—across both real and digital frontiers.
