Exploration is the process of exploring, an activity which has some expectation of discovery. Organised exploration is largely a human activity, but exploratory activity is common to most organisms capable of directed locomotion and the ability to learn, and has been described in, amongst others, social insects foraging behaviour, where feedback from returning individuals affects the activity of other members of the group. [1]
Geographical exploration, sometimes considered the default meaning for the more general term exploration, is the practice of discovering lands and regions of the planet Earth remote or relatively inaccessible from the origin of the explorer. [2] The surface of the Earth not covered by water has been relatively comprehensively explored, as access is generally relatively straightforward, but underwater and subterranean areas are far less known, and even at the surface, much is still to be discovered in detail in the more remote and inaccessible wilderness areas.
Two major eras of geographical exploration occurred in human history: The first, covering most of Human history, saw people moving out of Africa, settling in new lands, and developing distinct cultures in relative isolation. [3] Early explorers settled in Europe and Asia; about 14,000 years ago, some crossed the Ice Age land bridge from Siberia to Alaska, and moved southwards to settle in the Americas. [2] For the most part, these cultures were ignorant of each other's existence. [3] The second period of exploration, occurring over the last 10,000 years, saw increased cross-cultural exchange through trade and exploration, and marked a new era of cultural intermingling, and more recently, convergence. [3]
Early writings about exploration date back to the 4th millennium B.C. in ancient Egypt. One of the earliest and most impactful thinkers on exploration was Ptolemy in the 2nd century AD. Between the 5th century and 15th century AD, most exploration was done by Chinese and Arab explorers. This was followed by the Age of Discovery after European scholars rediscovered the works of early Latin and Greek geographers. While the Age of Discovery was partly driven by land routes outside of Europe becoming unsafe, [4] and a desire for conquest, the 17th century also saw exploration driven by nobler motives, including scientific discovery and the expansion of knowledge about the world. [2] This broader knowledge of the world's geography meant that people were able to make world maps, depicting all land known. The first modern atlas was the Theatrum Orbis Terrarum , published by Abraham Ortelius, which included a world map that depicted all of Earth's continents. [5] : 32
Underwater exploration is the exploration of any underwater environment, either by direct observation by the explorer, or by remote observation and measurement under the direction of the investigators. Systematic, targeted exploration, with simultaneous survey, and recording of data, followed by data processing, interpretation and publication, is the most effective method to increase understanding of the ocean and other underwater regions, so they can be effectively managed, conserved, regulated, and their resources discovered, accessed, and used. Less than 10% of the ocean has been mapped in any detail, even less has been visually observed, and the total diversity of life and distribution of populations is similarly incompletely known. [6]
Space exploration is the use of astronomy and space technology to explore outer space. [7] While the exploration of space is currently carried out mainly by astronomers with telescopes, its physical exploration is conducted both by uncrewed robotic space probes and human spaceflight. Space exploration, like its classical form astronomy, is one of the main sources for space science.
While the observation of objects in space, known as astronomy, predates reliable recorded history, it was the development of large and relatively efficient rockets during the mid-twentieth century that allowed physical extraterrestrial exploration to become a reality. Common rationales for exploring space include advancing scientific research, national prestige, uniting different nations, ensuring the future survival of humanity, and developing military and strategic advantages against other countries. [8]
Urban exploration is the exploration of manmade structures, usually abandoned ruins or hidden components of the manmade environment. Photography and historical interest/documentation are heavily featured in the hobby, sometimes involving trespassing onto private property. [9]
The activity presents various risks, including physical danger and, if done illegally and/or without permission, the possibility of arrest and punishment. Some activities associated with urban exploration violate local or regional laws and certain broadly interpreted anti-terrorism laws, or can be considered trespassing or invasion of privacy. [10]
Traditionally, mineral exploration relied on direct observation of mineralisation in rock outcrops or in sediments. More recently, however, mineral exploration also includes the use of geologic, geophysical, and geochemical tools to search for anomalies, which can narrow the search area. The area to be prospected should be covered sufficiently to minimize the risk of missing something important, but it can take into account previous experience that certain geological evidence correlates with a very low probability of finding the desired minerals. Other evidence indicates a high probability, making it efficient to concentrate on the areas of high probability when they are found, and for the skipping areas of very low probability. Once an anomaly has been identified and interpreted to be a prospect, more detailed exploration of the potential reserve can be done by soil sampling, drilling, seismic surveys, and similar methods to assess the most appropriate method and type of mining and the economic potential. [11]
In all these definitions there is an implication of novelty, or unfamiliarity or the expectation of discovery in the exploration, whereas a survey implies directed examination, but not necessarily discovery of any previously unknown or unexpected information. The activities are not mutually exclusive, and often occur simultaneously to a variable extent. The same field of investigation or region may be explored at different times by different explorers with different motivations, who may make similar or different discoveries.
Explorers:
Amerigo Vespucci was an Italian explorer and navigator from the Republic of Florence, from whose name the term "America" is derived.
Christopher Columbus was an Italian explorer and navigator from the Republic of Genoa who completed four Spanish-based voyages across the Atlantic Ocean sponsored by the Catholic Monarchs, opening the way for the widespread European exploration and colonization of the Americas. His expeditions were the first known European contact with the Caribbean and Central and South America.
Dom Henrique of Portugal, Duke of Viseu, better known as Prince Henry the Navigator, was a central figure in the early days of the Portuguese Empire and in the 15th-century European maritime discoveries and maritime expansion. Through his administrative direction, he is regarded as the main initiator of what would be known as the Age of Discovery. Henry was the fourth child of King John I of Portugal, who founded the House of Aviz.
The history of North America encompasses the past developments of people populating the continent of North America. While it was commonly accepted that the continent first became inhabited by humans when individuals migrated across the Bering Sea 40,000 to 17,000 years ago, more recent discoveries may have pushed those estimates back at least another 90,000 years. People settled throughout the continent and, over time, developed into diverse communities, from the Inuit in the far north to the Mayans and Aztecs in the south. These complex communities each developed their own unique cultures and ways of life.
During the Age of Discovery, a large scale colonization of the Americas, involving a number of European countries, took place primarily between the late 15th century and the early 19th century. The Norse explored and colonized areas of Europe and the North Atlantic, colonizing Greenland and creating a short term settlement near the northern tip of Newfoundland circa 1000 AD. However, due to its long duration and importance, the later colonization by the European powers involving the continents of North America and South America is more well-known.
Giovanni da Verrazzano was an Italian (Florentine) explorer of North America, in the service of King Francis I of France.
Geographical exploration, sometimes considered the default meaning for the more general term exploration, refers to the practice of discovering remote lands and regions of the planet Earth. It is studied by geographers and historians.
Conquistadors or conquistadores is the term used to refer to Spanish and Portuguese soldiers and explorers who carried out the conquests and explorations of the Age of Discovery. Conquistadors sailed beyond the Iberian Peninsula to the Americas, Oceania, Africa and Asia, establishing new colonies and trade routes. They brought much of the "New World" under the dominion of Spain and Portugal.
Stephen J. Pyne (1949–present) is an emeritus professor at Arizona State University, specializing in environmental history, the history of exploration, and especially the history of fire.
The Age of Discovery, also known as the Age of Exploration, was part of the early modern period and largely overlapping with the Age of Sail. It was a period from approximately the late 15th century to the 17th century, during which seafarers from a number of European countries explored, colonized, and conquered regions across the globe. The Age of Discovery was a transformative period in world history when previously isolated parts of the world became connected to form the world system and laid the groundwork for globalization. The extensive overseas exploration, particularly the opening of maritime routes to the Indies and the European colonization of the Americas by the Spanish and Portuguese, later joined by the English, French and Dutch, spurred in the International global trade. The interconnected global economy of the 21st century has its origins in the expansion of trade networks during this era.
Felipe Fernández-Armesto is a British professor of history and author of several popular works, notably on cultural and environmental history.
Big History is an academic discipline which examines history from the Big Bang to the present. Big History resists specialization, and searches for universal patterns or trends. It examines long time frames using a multidisciplinary approach based on combining numerous disciplines from science and the humanities, and explores human existence in the context of this bigger picture. It integrates studies of the cosmos, Earth, life, and humanity using empirical evidence to explore cause-and-effect relations, and is taught at universities and primary and secondary schools often using web-based interactive presentations.
Between 1492 and 1504, the Italian navigator and explorer Christopher Columbus led four transatlantic maritime expeditions in the name of the Catholic Monarchs of Spain to the Caribbean and to Central and South America. These voyages led to the widespread knowledge of the New World. This breakthrough inaugurated the period known as the Age of Discovery, which saw the colonization of the Americas, a related biological exchange, and trans-Atlantic trade. These events, the effects and consequences of which persist to the present, are often cited as the beginning of the modern era.
Atlantic history is a specialty field in history that studies the Atlantic World in the early modern period. The Atlantic World was created by the contact between Europeans and the Americas, and Atlantic History is the study of that world. It is premised on the idea that, following the rise of sustained European contact with the New World in the 16th century, the continents that bordered the Atlantic Ocean—the Americas, Europe, and Africa—constituted a regional system or common sphere of economic and cultural exchange that can be studied as a totality.
William Harry Goetzmann was an American historian and emeritus professor in the American Studies and American Civilization Programs at the University of Texas at Austin. He attended Yale University as a graduate student and was friends with Tom Wolfe while there. His work on the American West won him the highest prizes for historians, the Parkman Prize and the Pulitzer Prize. He has written and published extensively on American philosophy, American political history, and the American arts. An advocate for the importance of history as a public discussion, he has served in various capacities in television and film production, notably for PBS. He was most recently the Jack S. Blanton Sr. Chair Emeritus in History and American Studies. His last book published during his lifetime was Beyond the Revolution: A History of American Thought From Paine to Pragmatism (2009).
The exploration of North America by European sailors and geographers was an effort by major European powers to map and explore the continent with the goal of economic, religious and military expansion. The combative and rapid nature of this exploration is the result of a series of countering actions by neighboring European nations to ensure no single country had garnered enough wealth and power from the Americas to militarily tip the scales over on the European continent. It spanned the late 15th to early 17th centuries, and consisted primarily of expeditions funded by Spain, England, France, and Portugal. See also the European colonization of the Americas.
Walter Scheidel is an Austrian historian who teaches ancient history at Stanford University, California. Scheidel's main research interests are ancient social and economic history, pre-modern historical demography, and comparative and transdisciplinary approaches to world history.
This prize should not be confused with the Watson Davis Award from the Association for Information Science and Technology.
The Watson Davis and Helen Miles Davis Prize of the History of Science Society is awarded yearly for a book published, during the past three years, on the history of science for a wide public. The book should "introduce an entire field, a chronological period, a national tradition, or the work of a noteworthy individual." The book can be written by multiple authors or editors and is required to be written in English and suitable for an audience including undergraduates and readers without specialized, technical knowledge. The author receives 1,000 U.S. dollars and a certificate. The prize, established in 1985, is named in honor of Watson Davis and Helen Miles Davis who were science popularizers in the USA.
Amerigo Vespucci's Letter from Seville, written to his patron Lorenzo di Pierfrancesco de' Medici, describes experiences on Alonso de Ojeda's May 1499 voyage. Vespucci's findings during the Age of Discovery led Spain people to believe that North and South America were not connected to Asia, which was a common belief at the time and was even held by Vespucci himself. Despite the surrounding controversy among many historians about which Vespucci letters were real, and which ones were forged, this particular letter of Vespucci's is notable for its detailed description of the Brazilian coast and its inhabitants.
