In which John Green teaches you about the beginning of the so-called Age of Discovery. You've probably heard of Christopher Columbus, who "discovered" America in 1492, but what about Vasco da Gama? How about Zheng He? Columbus gets a bad rap from many modern historians, but it turns out he was pretty important as far as the history of the world goes. That said, he wasn't the only pioneer plying the seas in the 1400s. In Portugal, Vasco da Gama was busy integrating Europe into the Indian Ocean Trade by sailing around Africa. Chinese admiral Zheng He was also traveling far and wide in the largest wooden ships ever built. Columbus, whether portrayed as hero or villain, is usually credited as the great sailor of the 15th century, but he definitely wasn't the only contender. What better way to settle this question than with a knock-down, drag-out, no holds barred, old-fashioned battle royal? We were going to make it a cage match, but welding is EXPENSIVE.
All humans explore the world around them to make sense of his or her surroundings. These are some of the most famous explorers in human history. It is by no means a complete list.
In the late 1400s, several developments in Europe paved the way for European exploration in the Americas. In this video, Kim discusses how Portugal led the charge with new navigation technology, and how the unification of Spain set the stage for Columbus's voyage in 1492.

Exploration is the act of searching for the purpose of discovery of information or resources. Exploration occurs in all non-sessile animal species, including humans. In human history, its most dramatic rise was during the Age of Discovery when European explorers sailed and charted much of the rest of the world for a variety of reasons. Since then, major explorations after the Age of Discovery have occurred for reasons mostly aimed at information discovery.
In scientific research, exploration is one of three purposes of empirical research (the other two being description and explanation). The term is often used metaphorically.
