A physical map of Earth

Geography (from Ancient Greek γεωγραφία geōgraphía; combining gê 'Earth' and gráphō 'write') is the study of the lands, features, inhabitants, and phenomena of Earth. Geography is an all-encompassing discipline that seeks an understanding of Earth and its human and natural complexities—not merely where objects are, but also how they have changed and come to be. While geography is specific to Earth, many concepts can be applied more broadly to other celestial bodies in the field of planetary science. Geography has been called "a bridge between natural science and social science disciplines."

Origins of many of the concepts in geography can be traced to Greek Eratosthenes of Cyrene, who may have coined the term "geographia" (c. 276 BC – c. 195/194 BC). The first recorded use of the word γεωγραφία was as the title of a book by Greek scholar Claudius Ptolemy (100 – 170 AD). This work created the so-called "Ptolemaic tradition" of geography, which included "Ptolemaic cartographic theory." However, the concepts of geography (such as cartography) date back to the earliest attempts to understand the world spatially, with the earliest example of an attempted world map dating to the 9th century BCE in ancient Babylon. The history of geography as a discipline spans cultures and millennia, being independently developed by multiple groups, and cross-pollinated by trade between these groups. The core concepts of geography consistent between all approaches are a focus on space, place, time, and scale.

Today, geography is an extremely broad discipline with multiple approaches and modalities. There have been multiple attempts to organize the discipline, including the four traditions of geography, and into branches. Techniques employed can generally be broken down into quantitative and qualitative approaches, with many studies taking mixed-methods approaches. Common techniques include cartography, remote sensing, interviews, and surveying. (Full article...)

  The Maya civilization (/ˈmaɪə/) was a Mesoamerican civilization that existed from antiquity to the early modern period. It is known by its ancient temples and glyphs (script). The Maya script is the most sophisticated and highly developed writing system in the pre-Columbian Americas. The civilization is also noted for its art, architecture, mathematics, calendar, and astronomical system.
  
  The Maya civilization developed in the Maya Region, an area that today comprises southeastern Mexico, all of Guatemala and Belize, and the western portions of Honduras and El Salvador. It includes the northern lowlands of the Yucatán Peninsula and the Guatemalan Highlands of the Sierra Madre, the Mexican state of Chiapas, southern Guatemala, El Salvador, and the southern lowlands of the Pacific littoral plain. Today, their descendants, known collectively as the Maya, number well over 6 million individuals, speak more than twenty-eight surviving Mayan languages, and reside in nearly the same area as their ancestors.

  Portrait by Ferdinand Krumholz, 1850

  
  Dom Pedro Afonso (19 July 1848 – 10 January 1850) was the Prince Imperial and heir apparent to the throne of the Empire of Brazil. Born at the Palace of São Cristóvão in Rio de Janeiro, he was the second son and youngest child of Emperor Dom Pedro II and Dona Teresa Cristina of the Two Sicilies, and thus a member of the Brazilian branch of the House of Braganza. Pedro Afonso was seen as vital to the future viability of the monarchy, which had been put in jeopardy by the death of his older brother Dom Afonso almost three years earlier.
  
  Pedro Afonso's death from fever at the age of one devastated the Emperor, and the imperial couple had no further children. Pedro Afonso's older sister Dona Isabel became heiress, but Pedro II was unconvinced that a woman could ever be accepted as monarch by the ruling elite. He excluded Isabel from matters of state and failed to provide training for her possible role as empress. With no surviving male children, the Emperor came to understand that the imperial line was destined to end with his own death. (Full article...)

  The Willamette passing through Downtown Portland in the 1980s

  
  The Willamette River (/wɪˈlæmɪt/ wil-AM-it) is a major tributary of the Columbia River, accounting for 12 to 15 percent of the Columbia's flow. The Willamette's main stem is 187 miles (301 km) long, lying entirely in northwestern Oregon in the United States. Flowing northward between the Oregon Coast Range and the Cascade Range, the river and its tributaries form the Willamette Valley, a basin that contains two-thirds of Oregon's population, including the state capital, Salem, and the state's largest city, Portland, which surrounds the Willamette's mouth at the Columbia.
  
  Originally created by plate tectonics about 35 million years ago and subsequently altered by volcanism and erosion, the river's drainage basin was significantly modified by the Missoula Floods at the end of the most recent ice age. Humans began living in the watershed over 10,000 years ago. There were once many tribal villages along the lower river and in the area around its mouth on the Columbia. Indigenous peoples lived throughout the upper reaches of the basin as well. (Full article...)

  Ford Island, located within
  Pearl Harbor, Oahu, Hawaii

  
  Ford Island (Hawaiian: Poka ʻAilana) is an islet in the center of Pearl Harbor, Oahu, in the U.S. state of Hawaii. It has been known as Rabbit Island, Marín's Island, and Little Goats Island; its native Hawaiian name is Mokuʻumeʻume. The island had an area of 334 acres (135 ha) when it was surveyed in 1825, which was increased during the 1930s to 441 acres (178 ha) with fill dredged out of Pearl Harbor by the United States Navy to deepen the harbor.
  
  The island was the site of an ancient Hawaiian fertility ritual, which was stopped by Christian missionaries during the 1830s. The island was given by Kamehameha I to Spanish deserter Francisco de Paula Marín, and later returned to the monarchy. After the island was bought at auction by James Isaac Dowsett and sold to Caroline Jackson, it became the property of Dr. Seth Porter Ford by marriage and was renamed Ford Island. After Ford's death, his son sold the island to the John Papa ʻĪʻī estate and it was converted into a sugarcane plantation. (Full article...)

  The Three Sisters, looking north

  
  The Three Sisters are closely spaced volcanic peaks in the U.S. state of Oregon. They are part of the Cascade Volcanic Arc, a segment of the Cascade Range in western North America extending from southern British Columbia through Washington and Oregon to Northern California. Each over 10,000 feet (3,000 meters) in elevation, they are the third-, fourth- and fifth-highest peaks in Oregon. Located in the Three Sisters Wilderness at the boundary of Lane and Deschutes counties and the Willamette and Deschutes national forests, they are about 10 miles (16 kilometers) south of the nearest town, Sisters. Diverse species of flora and fauna inhabit the area, which is subject to frequent snowfall, occasional rain, and extreme temperature variation between seasons. The mountains, particularly South Sister, are popular destinations for climbing and scrambling.
  
  Although they are often grouped together as one unit, the three mountains have their own individual geology and eruptive history. Neither North Sister nor Middle Sister has erupted in the last 14,000 years, and it is considered unlikely that either will ever erupt again. South Sister last erupted about 2,000 years ago and could erupt in the future, threatening life within the region. After satellite imagery detected ground inflation near South Sister in 2001, the United States Geological Survey improved monitoring in the immediate area. (Full article...)

  Bottled maple syrup

  
  Maple syrup is a syrup made from the sap of maple trees. In cold climates, these trees store starch in their trunks and roots before winter; the starch is then converted to sugar that rises in the sap in late winter and early spring. Maple trees are tapped by drilling holes into their trunks and collecting the sap, which is processed by heating to evaporate much of the water, leaving the concentrated syrup.
  
  Maple syrup was first made by the Indigenous peoples of Northeastern North America. The practice was adopted by European settlers, who gradually changed production methods. Technological improvements in the 1970s further refined syrup processing. Almost all of the world's maple syrup is produced in Canada and the United States. The Canadian province of Quebec is the largest producer, responsible for 70 per cent of the world's output; Canadian exports of maple syrup in 2016 were C$487 million (about US$360 million), with Quebec accounting for some 90 per cent of this total.

  Tiruchirappalli (Tamil pronunciation: [ˈt̪iɾɯtːʃiɾaːpːaɭːi] , formerly called Trichinopoly in English, also known as Tiruchi or Trichy), is a major tier II city in the Indian state of Tamil Nadu and the administrative headquarters of Tiruchirappalli district. The city is credited with being the best livable city, the cleanest city of Tamil Nadu, as well as the fifth safest city for women in India. It is the fourth largest city as well as the fourth largest urban agglomeration in the state. Located 322 kilometres (200 mi) south of Chennai and 374 kilometres (232 mi) north of Kanyakumari, Tiruchirappalli sits almost at the geographic centre of Tamil Nadu state. The Cauvery Delta begins 16 kilometres (9.9 mi) west of the city where the Kaveri river splits into two, forming the island of Srirangam which is now incorporated into the Tiruchirappalli City Municipal Corporation. The city occupies an area of 167.23 square kilometres (64.57 sq mi) and had a population of 916,857 in 2011.
  
  Tiruchirappalli's recorded history begins in the 3rd century BC, when it was under the rule of the Cholas. The city has also been ruled by the Mutharaiyars, Pallavas, Pandyas, Vijayanagar Empire, Nayak Dynasty, the Carnatic state and the British. The most prominent historical monuments in Tiruchirappalli include the Rockfort at Teppakulam, the Ranganathaswamy temple at Srirangam dedicated to the reclining form of Hindu God Vishnu, and is also the largest functioning temple in the world, and the Jambukeswarar temple at Thiruvanaikaval, which is also the largest temple for the Hindu God Shiva in the world. The archaeologically important town of Uraiyur, capital of the Early Cholas, is now a neighbourhood in Tiruchirappalli. The city played a critical role in the Carnatic Wars (1746–1763) between the British and the French East India companies. (Full article...)

  The Empire of Brazil was a 19th-century state that broadly comprised the territories which form modern Brazil and Uruguay until the latter achieved independence in 1828. The empire's government was a representative parliamentary constitutional monarchy under the rule of Emperors Pedro I and his son Pedro II. A colony of the Kingdom of Portugal, Brazil became the seat of the Portuguese Empire in 1808, when the Portuguese Prince regent, later King Dom John VI, fled from Napoleon's invasion of Portugal and established himself and his government in the Brazilian city of Rio de Janeiro. John VI later returned to Portugal, leaving his eldest son and heir-apparent, Pedro, to rule the Kingdom of Brazil as regent. On 7 September 1822, Pedro declared the independence of Brazil and, after waging a successful war against his father's kingdom, was acclaimed on 12 October as Pedro I, the first Emperor of Brazil. The new country was huge, sparsely populated, and ethnically diverse.
  
  Unlike most of the neighboring Hispanic American republics, Brazil had political stability, vibrant economic growth, constitutionally guaranteed freedom of speech, and respect for civil rights of its subjects, albeit with legal restrictions on women and slaves, the latter regarded as property and not citizens. The Empire's bicameral parliament was elected under comparatively democratic methods for the era, as were the provincial and local legislatures. This led to a long ideological conflict between Pedro I and a sizable parliamentary faction over the role of the monarch in the government. He also had to face other obstacles. The unsuccessful Cisplatine War against the neighboring United Provinces of the Río de la Plata in 1828 led to the secession of the province of Cisplatina (later to become Uruguay). In 1826, despite his role in Brazilian independence, he became the king of Portugal; he abdicated the Portuguese throne in favor of his eldest daughter. Two years later, she was usurped by Pedro I's younger brother Miguel. Unable to deal with both Brazilian and Portuguese affairs, Pedro I abdicated his Brazilian throne on 7 April 1831 and immediately departed for Europe to restore his daughter to the Portuguese throne.

  Michael was born near Apex, Iqaluit.

  
  Simonie Michael (Inuktitut: ᓴᐃᒨᓂ ᒪᐃᑯᓪ; first name also spelled Simonee, alternative surnames Michel or E7-551; March 2, 1933 – November 15, 2008) was a Canadian politician from the eastern Northwest Territories (now Nunavut) who was the first Inuk elected to a legislature in Canada. Before becoming involved in politics, Michael worked as a carpenter and business owner, and was one of very few translators between Inuktitut and English. He became a prominent member of the Inuit co-operative housing movement and a community activist in Iqaluit, and was appointed to a series of governing bodies, including the precursor to the Iqaluit City Council.
  
  After becoming the first elected Inuk member of the Northwest Territories Legislative Council, in 1966, Michael worked on infrastructural and public health initiatives. He is credited with bringing public attention to the dehumanizing effects of the disc number system that was used in place of surnames for Inuit, and with prompting the government to authorise Project Surname to replace the numbers with names.

  Mount Mazama collapsed into a caldera, which filled with water to form Crater Lake

  
  Mount Mazama (Tum-sum-ne in the Native American language Klamath) is a complex volcano in the western U.S. state of Oregon, in a segment of the Cascade Volcanic Arc and Cascade Range. The volcano is in Klamath County, in the southern Cascades, 60 miles (97 km) north of the Oregon–California border. Its collapse, due to the eruption of magma emptying the underlying magma chamber, formed a caldera that holds Crater Lake (Giiwas in the Native American language Klamath). Mount Mazama originally had an elevation of 12,000 feet (3,700 m), but following its climactic eruption this was reduced to 8,157 feet (2,486 m). Crater Lake is 1,943 feet (592 m) deep, the deepest freshwater body in the U.S. and the second deepest in North America after Great Slave Lake in Canada.
  
  Mount Mazama formed as a group of overlapping volcanic edifices such as shield volcanoes and small composite cones, becoming active intermittently until its climactic eruption 7,700 years ago. This eruption, the largest known within the Cascade Volcanic Arc in a million years, destroyed Mazama's summit, reducing its approximate 12,000-foot (3,700 m) height by about 1 mile (1,600 m). Much of the edifice fell into the volcano's partially emptied neck and magma chamber, creating a caldera. The region's volcanic activity results from the subduction of the offshore oceanic plate, and is influenced by local extensional faulting. Mazama is dormant, but the U.S. Geological Survey says eruptions on a smaller scale are likely, which would pose a threat to its surroundings. (Full article...)

  Australia, officially the Commonwealth of Australia, is a country comprising the mainland of the Australian continent, the island of Tasmania and numerous smaller islands. Australia has a total area of 7,688,287 km² (2,968,464 sq mi), making it the sixth-largest country in the world and the largest country by area in Oceania. It is the world's oldest, flattest, and driest inhabited continent, with some of the least fertile soils. It is a megadiverse country, and its size gives it a wide variety of landscapes and climates including deserts in the interior and tropical rainforests along the coast.
  
  The ancestors of Aboriginal Australians began arriving from south-east Asia 50,000 to 65,000 years ago, during the last glacial period. They settled on the continent and formed approximately 250 distinct language groups by the time of European settlement, maintaining some of the longest known continuing artistic and religious traditions in the world. Australia's written history commenced with Dutch exploration of most of the coastline in the 17th-century. British colonisation began in 1788 with the establishment of the penal colony of New South Wales. By the mid-19th century, most of the continent had been explored by European settlers and five additional self-governing British colonies were established, each gaining responsible government by 1890. The colonies federated in 1901, forming the Commonwealth of Australia. This continued a process of increasing autonomy from the United Kingdom, highlighted by the Statute of Westminster Adoption Act 1942, and culminating in the Australia Acts of 1986. (Full article...)

  The Central European borders of Brandenburg–Prussia (blue-green) and the Habsburg monarchy (red) in 1756, after Prussia's seizure of Silesia in the First Silesian War

  
  The Silesian Wars (German: Schlesische Kriege) were three wars fought in the mid-18th century between Prussia (under King Frederick the Great) and Habsburg Austria (under Empress Maria Theresa) for control of the Central European region of Silesia (now in south-western Poland). The First (1740–1742) and Second (1744–1745) Silesian Wars formed parts of the wider War of the Austrian Succession, in which Prussia was a member of a coalition seeking territorial gain at Austria's expense. The Third Silesian War (1756–1763) was a theatre of the global Seven Years' War, in which Austria in turn led a coalition of powers aiming to seize Prussian territory.
  
  No particular event triggered the wars. Prussia cited its centuries-old dynastic claims on parts of Silesia as a casus belli, but Realpolitik and geostrategic factors also played a role in provoking the conflict. Maria Theresa's contested succession to the Habsburg monarchy under the Pragmatic Sanction of 1713 provided an opportunity for Prussia to strengthen itself relative to regional rivals such as Saxony and Bavaria.

  Columbia Slough near mouth

  
  The Columbia Slough is a narrow waterway, about 19 miles (31 km) long, in the floodplain of the Columbia River in the U.S. state of Oregon. From its source in the Portland suburb of Fairview, the Columbia Slough meanders west through Gresham and Portland to the Willamette River, about 1 mile (1.6 km) from the Willamette's confluence with the Columbia. It is a remnant of the historic wetlands between the mouths of the Sandy River to the east and the Willamette River to the west. Levees surround much of the main slough as well as many side sloughs, detached sloughs, and nearby lakes. Drainage district employees control water flows with pumps and floodgates. Tidal fluctuations cause reverse flow on the lower slough.
  
  The Columbia floodplain, formed by geologic processes including lava flows, volcanic eruptions, and the Missoula Floods, is part of the Portland Basin, which extends across the Columbia River from Multnomah County, Oregon, into Clark County, Washington. Five percent of Oregon's population, about 158,000 people, live in the slough watershed of about 51 square miles (130 km²). Municipal wells near the upper slough provide supplemental drinking water to Portland and nearby cities. The cities, the drainage districts, the county, and a regional government, Metro, have overlapping jurisdictions in the watershed. A regional agency operates Portland International Airport along the middle slough and marine terminals near the lower slough. The Oregon Department of Environmental Quality (DEQ) and the city's Bureau of Environmental Services (BES) deal with environmental issues. (Full article...)

  The Count of Porto Alegre around age 61, c. 1865

  
  Manuel Marques de Sousa, Count of Porto Alegre (13 June 1804 – 18 July 1875), nicknamed "the Gloved Centaur", was an army officer, politician and abolitionist of the Empire of Brazil. Born into a wealthy family of military background, Manuel Marques de Sousa joined the Portuguese Army in Brazil in 1817 when he was little more than a child. His military initiation occurred in the conquest of the Banda Oriental (Eastern Bank), which was annexed and became the southernmost Brazilian province of Cisplatina in 1821. For most of the 1820s, he was embroiled in the Brazilian effort to keep Cisplatina as part of its territory: first during the struggle for Brazilian independence and then in the Cisplatine War. It would ultimately prove a futile attempt, as Cisplatina successfully separated from Brazil to become the independent nation of Uruguay in 1828.
  
  A few years later, in 1835 his native province of Rio Grande do Sul was engulfed in a secessionist rebellion, the Ragamuffin War. The conflict lasted for almost ten years, and the Count was leading military engagements for most of that time. He played a decisive role in saving the provincial capital from the Ragamuffin rebels, allowing forces loyal to the legitimate government to secure a key foothold. In 1852, he led a Brazilian division during the Platine War in an invasion of the Argentine Confederation that overthrew its dictator. He was awarded a noble title, eventually raised from baron to viscount and finally to count. (Full article...)

  Map of Lajjun Sanjak, the territory governed by the Turabay dynasty for most of the 16th and 17th centuries

  
  The Turabay dynasty (Arabic: آل طرباي, romanized: Āl Ṭurabāy) was a family of Bedouin emirs in northern Palestine who served as the multazims (tax farmers) and sanjak-beys (district governors) of Lajjun Sanjak during Ottoman rule in the 16th–17th centuries. The sanjak (district) spanned the towns of Lajjun, Jenin and Haifa, and the surrounding countryside. The progenitors of the family had served as chiefs of Marj ibn Amir (the Plain of Esdraelon or Jezreel Valley) under the Egypt-based Mamluks in the late 15th century.
  
  During the conquest of the Levant and Egypt by the Ottoman Empire in 1516–1517, the Turabay chief Qaraja and his son Turabay aided the forces of Ottoman Sultan Selim I. The Ottomans kept them in their Mamluk-era role as guardians of the strategic Via Maris and Damascus–Jerusalem highways and rewarded them with tax farms in northern Palestine. Their territory became a sanjak in 1559 and Turabay's son Ali became its first governor. His brother Assaf was appointed in 1573, serving for ten years before being dismissed and exiled to Rhodes for involvement in a rebellion. His nephew Turabay was appointed in 1589 and remained in office until his death in 1601. His son and successor Ahmad, the most prominent chief of the dynasty, ruled Lajjun for nearly a half-century and repulsed attempts by the powerful Druze chief and Ottoman governor of Sidon-Beirut and Safed, Fakhr al-Din Ma'n, to take over Lajjun and Nablus in the 1620s. He consolidated the family's alliance with the Ridwan and Farrukh governing dynasties of Gaza and Nablus, which remained intact until the dynasties' demise toward the end of the century.

A city is a human settlement of a substantial size. The term "city" has different meanings around the world and in some places the settlement can be very small. Even where the term is limited to larger settlements, there is no universally agreed definition of the lower boundary for their size. In a narrower sense, a city can be defined as a permanent and densely populated place with administratively defined boundaries whose members work primarily on non-agricultural tasks. Cities generally have extensive systems for housing, transportation, sanitation, utilities, land use, production of goods, and communication. Their density facilitates interaction between people, government organizations, and businesses, sometimes benefiting different parties in the process, such as improving the efficiency of goods and service distribution.

  Typhoon Noru

  Photograph credit: NASA; edited by Meow

  Typhoon Noru was the second-longest lasting tropical cyclone of the northwest Pacific Ocean on record. The fifth named storm of the 2017 Pacific typhoon season, it formed on July 19 and reached peak intensity on July 31 with 175 km/h (110 mph) 10-minute sustained winds. By this time, as shown in this satellite image, the typhoon was located south of Iwo Jima, and had taken on annular characteristics, with a symmetric ring of deep convection surrounding a 30 km (19 mi) well defined eye and fairly uniform cloud top temperatures. Traveling northwestward over an area of low ocean heat content, the eye became enlarged and ragged as the system weakened. By the time Noru made landfall over Wakayama Prefecture, Japan, on August 7, it had been downgraded to a severe tropical storm. It then dissipated over the Sea of Japan on August 9 as an extratropical cyclone.

  Mercator projection

  Map: Strebe, using Geocart

  The Mercator projection is a cylindrical map projection presented by the Flemish geographer and cartographer Gerardus Mercator in 1569. Because it represents paths of constant course as straight lines, it long served as the standard map projection for nautical purposes. However, it distorts the size of objects as the latitude increases: thus areas in the mid-latitudes appear significantly larger than their actual size relative to those the equator, and those near the poles are even more exaggerated. Most modern atlases no longer use the Mercator projection for world maps or for areas distant from the equator, preferring other cylindrical projections, or forms of equal-area projection.

  Compass rose

  Illustration credit: Joaquim Alves Gaspar, after Jorge de Aguiar

  A compass rose, sometimes called a windrose or rose of the winds, is a figure on a compass, map, nautical chart, or monument used to display the orientation of the cardinal directions (north, east, south, and west) and their intermediate points. It is also the term for the graduated markings found on the traditional magnetic compass. Today, a form of compass rose is found on, or featured in, almost all navigation systems, including nautical charts, non-directional beacons, VHF omnidirectional range systems, GPS, and similar equipment.
  
  This picture is an illustration of a compass rose, copied from a 1492 portolan chart by Portuguese navigator and cartographer Jorge de Aguiar, now in the Beinecke Rare Book & Manuscript Library.

  Equirectangular projection

  Map: Strebe, using Geocart

  The equirectangular projection is a simple map projection attributed to Marinus of Tyre, who Ptolemy claims invented the projection about AD 100. The projection maps meridians to vertical straight lines of constant spacing, and circles of latitude to horizontal straight lines of constant spacing. The projection is neither equal area nor conformal. Because of the distortions introduced by this projection, it has few applications beyond base imagery to be reprojected to some more useful projection.

  The Gall–Peters projection, named after James Gall and Arno Peters, is a specialization of a configurable equal-area map projection known as the cylindrical equal-area projection. It achieved considerable notoriety in the late 20th century as the centerpiece of a controversy surrounding the political implications of map design; Peters promoted it as a more faithful representation than the Mercator projection, which inflates the sizes of regions farther from the equator and thus makes the (mostly technologically underdeveloped) equatorial countries appear smaller and therefore, according to Peters, less significant.

Boone depicted in an 1820 portrait by Chester Harding, the only known portrait of him made during his lifetime

Daniel Boone (November 2 [O.S. October 22], 1734 – September 26, 1820) was an American pioneer and frontiersman whose exploits made him one of the first folk heroes of the United States. He became famous for his exploration and settlement of Kentucky, which was then beyond the western borders of the Thirteen Colonies. In 1775, Boone founded the Wilderness Road through the Cumberland Gap and into Kentucky, in the face of resistance from Native Americans. He founded Boonesborough, one of the first English-speaking settlements west of the Appalachian Mountains. By the end of the 18th century, more than 200,000 people had entered Kentucky by following the route marked by Boone.

He served as a militia officer during the Revolutionary War (1775–1783), which in Kentucky was fought primarily between American settlers and British-allied Indians. Boone was taken in by Shawnees in 1778 and adopted into the tribe, but he resigned and continued to help protect the Kentucky settlements. He also left due to the Shawnee Indians torturing and killing one of his sons. He was elected to the first of his three terms in the Virginia General Assembly during the war and fought in the Battle of Blue Licks in 1782, one of the last battles of the American Revolution. He worked as a surveyor and merchant after the war, but went deep into debt as a Kentucky land speculator. He resettled in Missouri in 1799, where he spent most of the last two decades of his life, frustrated with legal problems resulting from his land claims. (Full article...)

  A map of the United States showing its 50 states, federal district and five inhabited territories. Alaska, Hawaii, and the territories are shown at different scales, and the Aleutian Islands and the uninhabited northwestern Hawaiian Islands are omitted from the map.

  
  The United States of America is a federal republic consisting of 50 states, a federal district (Washington, D.C., the capital city of the United States), five major territories, and various minor islands. Both the states and the United States as a whole are each sovereign jurisdictions. The Tenth Amendment to the United States Constitution allows states to exercise all powers of government not delegated to the federal government. Each state has its own constitution and government, and all states and their residents are represented in the federal Congress, a bicameral legislature consisting of the Senate and the House of Representatives. Each state elects two senators, while representatives are distributed among the states in proportion to the most recent constitutionally mandated decennial census. Additionally, each state is entitled to select a number of electors to vote in the Electoral College, the body that elects the president of the United States, equal to the total of representatives and senators in Congress from that state. The federal district does not have representatives in the Senate, but has a non-voting delegate in the House, and it is also entitled to electors in the Electoral College. Congress can admit more states, but it cannot create a new state from territory of an existing state or merge two or more states into one without the consent of all states involved, and each new state is admitted on an equal footing with the existing states.

  The Blue Marble, Apollo 17, December 1972

  
  Earth is the third planet from the Sun and the only astronomical object known to harbor life. This is enabled by Earth being an ocean world, the only one in the Solar System sustaining liquid surface water. Almost all of Earth's water is contained in its global ocean, covering 70.8% of Earth's crust. The remaining 29.2% of Earth's crust is land, most of which is located in the form of continental landmasses within Earth's land hemisphere. Most of Earth's land is at least somewhat humid and covered by vegetation, while large sheets of ice at Earth's polar deserts retain more water than Earth's groundwater, lakes, rivers and atmospheric water combined. Earth's crust consists of slowly moving tectonic plates, which interact to produce mountain ranges, volcanoes, and earthquakes. Earth has a liquid outer core that generates a magnetosphere capable of deflecting most of the destructive solar winds and cosmic radiation. (Full article...)

  Map of the Chagos Archipelago

  
  The Chagos Archipelago (/ˈtʃɑːɡəs, -ɡoʊs/) or Chagos Islands (formerly the Bassas de Chagas, and later the Oil Islands) is a group of seven atolls comprising more than 60 islands in the Indian Ocean about 500 kilometres (310 mi) south of the Maldives archipelago. This chain of islands is the southernmost archipelago of the Chagos–Laccadive Ridge, a long submarine mountain range in the Indian Ocean. In its north are the Salomon Islands, Nelsons Island and Peros Banhos; towards its south-west are the Three Brothers, Eagle Islands, Egmont Islands and Danger Island; southeast of these is Diego Garcia, by far the largest island. All are low-lying atolls, save for a few extremely small instances, set around lagoons. (Full article...)

  London is the capital and largest city of both England and the United Kingdom, with a population of 8,866,180 in 2022. The wider metropolitan area is the largest in Western Europe, with a population of 14.9 million. London stands on the River Thames in southeast England, at the head of a 50-mile (80 km) estuary down to the North Sea, and has been a major settlement for nearly 2,000 years. Its ancient core and financial centre, the City of London, was founded by the Romans as Londinium and has retained its medieval boundaries. The City of Westminster, to the west of the City of London, has been the centuries-long host of the national government and parliament. London grew rapidly in the 19th century, becoming the world's largest city at the time. Since the 19th century, the name "London" has referred to the metropolis around the City of London, historically split between the counties of Middlesex, Essex, Surrey, Kent, and Hertfordshire, which since 1965 has largely comprised the administrative area of Greater London, governed by 33 local authorities and the Greater London Authority.

  Generation X (often shortened to Gen X) is the demographic cohort following the Baby Boomers and preceding Millennials. Researchers and popular media often use the mid-1960s as its starting birth years and the late 1970s as its ending birth years, with the generation being generally defined as people born from 1965 to 1980. By this definition and U.S. Census data, there are 65.2 million Gen Xers in the United States as of 2019. Most of Generation X are the children of the Silent Generation and early Baby Boomers; Xers are also often the parents of Millennials and Generation Z. (Full article...)
