Navigating the Age of Exploration

The video discusses the European exploration era starting in the 1400s, highlighting the role of technological advancements in navigation. Key tools like the compass, astrolabe, quadrant, and caravel are explored, detailing their origins, development, and impact on exploration. The compass, originating from China, was crucial for navigation when celestial bodies were not visible. The astrolabe, used for determining latitude, was introduced to Europe from the Arabic world. The quadrant, a more practical tool, replaced the astrolabe in the 1600s. The caravel, a ship with advanced design, facilitated long-distance trade and exploration. These tools were vital for European exploration, enabled by cultural exchanges from Asia.
