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...)
T2 was a seagoing torpedo boat operated by the Royal Yugoslav Navy between 1923 and 1939. Originally 77 T, a 250t-class torpedo boat of the Austro-Hungarian Navy built in 1914, she was armed with two 66 mm (2.6 in) guns and four 450 mm (17.7 in) torpedo tubes, and could carry 10–12 naval mines. She saw active service during World War I, performing convoy, patrol, escort, minesweeping and minelaying tasks, anti-submarine operations, and shore bombardment missions. In 1917, the suffixes of all Austro-Hungarian torpedo boats were removed, and thereafter she was referred to as 77. The vessel was in the Bocche di Cattaro during the short-lived mutiny by Austro-Hungarian sailors in early February 1918; members of her crew raised the red flag but undertook no other mutinous actions. 77 was part of the escort force for the Austro-Hungarian dreadnought Szent István during the action that resulted in the sinking of that ship by Italian torpedo boats in June 1918.
Following Austria-Hungary's defeat in 1918, 77 was allocated to the Navy of the Kingdom of Serbs, Croats and Slovenes, which later became the Royal Yugoslav Navy, and was renamed T2 and had her armament upgraded. At the time, she and seven other 250t-class boats were the only modern sea-going vessels of the fledgling maritime force. During the interwar period, the navy was involved in training exercises and cruises to friendly ports, but activity was limited by reduced naval budgets. Worn out after twenty-five years of service, T2 was stricken from the naval register and scrapped in 1939. (Full article...)

The Ross Sea party was a component of Sir Ernest Shackleton's 1914–1917 Imperial Trans-Antarctic Expedition. Its task was to lay a series of supply depots across the Great Ice Barrier from the Ross Sea to the Beardmore Glacier, along the polar route established by earlier Antarctic expeditions. The expedition's main party, under Shackleton, was to land near Vahsel Bay on the Weddell Sea on the opposite coast of Antarctica, and to march across the continent via the South Pole to the Ross Sea. As the main party would be unable to carry sufficient fuel and supplies for the whole distance, their survival depended on the Ross Sea party setting up supply depots, which would cover the final quarter of their journey.
Shackleton set sail from London on his ship Endurance, bound for the Weddell Sea in August 1914. Meanwhile, the Ross Sea party personnel gathered in Australia, prior to departure for the Ross Sea in the second expedition ship, SY Aurora. Organisational and financial problems delayed their start until December 1914, which shortened their first depot-laying season. After their arrival the inexperienced party struggled to master the art of Antarctic travel, in the process losing most of their sled dogs. (Full article...)

India, officially the Republic of India (ISO: Bhārat Gaṇarājya), is a country in South Asia. It is the seventh-largest country by area; the most populous country with effect from June 2023; and from the time of its independence in 1947, the world's most populous democracy. Bounded by the Indian Ocean on the south, the Arabian Sea on the southwest, and the Bay of Bengal on the southeast, it shares land borders with Pakistan to the west; China, Nepal, and Bhutan to the north; and Bangladesh and Myanmar to the east. In the Indian Ocean, India is in the vicinity of Sri Lanka and the Maldives; its Andaman and Nicobar Islands share a maritime border with Thailand, Myanmar, and Indonesia.
Modern humans arrived on the Indian subcontinent from Africa no later than 55,000 years ago.
Their long occupation, initially in varying forms of isolation as hunter-gatherers, has made the region highly diverse, second only to Africa in human genetic diversity. Settled life emerged on the subcontinent in the western margins of the Indus river basin 9,000 years ago, evolving gradually into the Indus Valley Civilisation of the third millennium BCE.
By 1200 BCE, an archaic form of Sanskrit, an Indo-European language, had diffused into India from the northwest. Its evidence today is found in the hymns of the Rigveda. Preserved by an oral tradition that was resolutely vigilant, the Rigveda records the dawning of Hinduism in India. The Dravidian languages of India were supplanted in the northern and western regions.
By 400 BCE, stratification and exclusion by caste had emerged within Hinduism,
and Buddhism and Jainism had arisen, proclaiming social orders unlinked to heredity.
Early political consolidations gave rise to the loose-knit Maurya and Gupta Empires based in the Ganges Basin.
Their collective era was suffused with wide-ranging creativity, but also marked by the declining status of women, and the incorporation of untouchability into an organised system of belief. In South India, the Middle kingdoms exported Dravidian-languages scripts and religious cultures to the kingdoms of Southeast Asia. (Full article...)

Rashtrakuta (IAST: rāṣṭrakūṭa) (r. 753 – 982 CE) was a royal Indian dynasty ruling large parts of the Indian subcontinent between the 6th and 10th centuries. The earliest known Rashtrakuta inscription is a 7th-century copper plate grant detailing their rule from Manapur, a city in Central or West India. Other ruling Rashtrakuta clans from the same period mentioned in inscriptions were the kings of Achalapur and the rulers of Kannauj. Several controversies exist regarding the origin of these early Rashtrakutas, their native homeland and their language.
The Elichpur clan was a feudatory of the Badami Chalukyas, and during the rule of Dantidurga, it overthrew Chalukya Kirtivarman II and went on to build an empire with the Gulbarga region in modern Karnataka as its base. This clan came to be known as the Rashtrakutas of Manyakheta, rising to power in South India in 753 AD. At the same time the Pala dynasty of Bengal and the Prathihara dynasty of Gurjaratra were gaining force in eastern and northwestern India respectively. An Arabic text, Silsilat al-Tawarikh (851), called the Rashtrakutas one of the four principal empires of the world. (Full article...)
Luís Alves de Lima e Silva, Duke of Caxias (pronounced [kaˈʃi.ɐs]; 25 August 1803 – 7 May 1880), nicknamed "the Peacemaker" and "the Iron Duke", was an army officer, politician and monarchist of the Empire of Brazil. Like his father and uncles, Caxias pursued a military career. In 1823 he fought as a young officer in the Brazilian War for Independence against Portugal, then spent three years in Brazil's southernmost province, Cisplatina, as the government unsuccessfully resisted that province's secession in the Cisplatine War. Though his own father and uncles renounced Emperor Dom Pedro I during the protests of 1831, Caxias remained loyal. Pedro I abdicated in favor of his young son Dom Pedro II, whom Caxias instructed in swordsmanship and horsemanship and eventually befriended.
During Pedro II's minority the governing regency faced countless rebellions throughout the country. Again breaking with his father and other relatives sympathetic to the rebels, from 1839 to 1845 Caxias commanded loyalist forces suppressing such uprisings as the Balaiada, the Liberal rebellions of 1842 and the Ragamuffin War. In 1851, under his command, the Brazilian army prevailed against the Argentine Confederation in the Platine War; a decade later Caxias, as army marshal (the army's highest rank), led Brazilian forces to victory in the Paraguayan War. As a reward he was raised to the titled nobility, becoming successively a baron, count, and marquis, finally becoming the only person created duke during Pedro II's 58-year reign. (Full article...)

John William Beschter SJ (born Johann Wilhelm Beschter; German: [ˈjoːhan ˈvɪlhɛlm ˈbɛʃtɐ]; May 20, 1763 – January 6, 1842) was a Catholic priest and Jesuit from the Duchy of Luxembourg in the Austrian Netherlands. He emigrated to the United States as a missionary in 1807, where he ministered in rural Pennsylvania and Maryland. Beschter was the last Jesuit pastor of St. Mary's Church in Lancaster, as well as the pastor of St. John the Evangelist Church in Baltimore, Maryland. He was also a priest at several other German-speaking churches in Pennsylvania.
Beschter's ministerial work was punctuated by a time as master of novices at the new Jesuit novitiate at White Marsh Manor, as well as a brief term as president of Georgetown College in 1829. While in Maryland, he aligned himself with the Continental European Jesuits in the United States, who endorsed a monarchist view of ecclesiastical leadership. After his presidency, Beschter remained at Georgetown for a year as a professor of German, before returning to Paradise, Pennsylvania, where he lived out the last twelve years of his life as a priest.

The Quelccaya Ice Cap (also known as Quenamari Ice Cap) is the second largest glaciated area in the tropics, after Coropuna. Located in the Cordillera Oriental section of the Andes mountains in Peru, the cap covers an area of 42.8 square kilometres (16.5 sq mi) with ice up to 200 metres (660 ft) thick. It is surrounded by tall ice cliffs and a number of outlet glaciers, the largest of which is known as Qori Kalis Glacier; lakes, moraines, peat bogs and wetlands are also present. There is a rich flora and fauna, including birds that nest on the ice cap. Quelccaya is an important source of water, eventually melting and flowing into the Inambari and Vilcanota Rivers.
A number of ice cores have been obtained from Quelccaya, including two from 1983 that were the first recovered outside of the polar regions. Past climate states have been reconstructed from data in these ice cores; these include evidence of the Little Ice Age, regional droughts and wet periods with historical significance and past and recent El Niño events. The ice cap is regularly monitored and has a weather station. (Full article...)
Manzanar is the site of one of ten American concentration camps, where more than 120,000 Japanese Americans were incarcerated during World War II from March 1942 to November 1945. Although it had over 10,000 inmates at its peak, it was one of the smaller internment camps. It is located at the foot of the Sierra Nevada mountains in California's Owens Valley, between the towns of Lone Pine to the south and Independence to the north, approximately 230 miles (370 km) north of Los Angeles. Manzanar means "apple orchard" in Spanish. The Manzanar National Historic Site, which preserves and interprets the legacy of Japanese American incarceration in the United States, was identified by the United States National Park Service as the best-preserved of the ten former camp sites.
The first Japanese Americans arrived at Manzanar in March 1942, just one month after President Franklin D. Roosevelt signed Executive Order 9066, to build the camp their families would be staying in. Manzanar was in operation as an internment camp from 1942 until 1945. Since the last of those incarcerated left in 1945, former detainees and others have worked to protect Manzanar and to establish it as a National Historic Site to ensure that the history of the site, along with the stories of those who were incarcerated there, is recorded for current and future generations. The primary focus is the Japanese American incarceration era, as specified in the legislation that created the Manzanar National Historic Site. The site also interprets the former town of Manzanar, the ranch days, the settlement by the Owens Valley Paiute, and the role that water played in shaping the history of the Owens Valley.

The Romney Literary Society (also known as the Literary Society of Romney) existed from January 30, 1819, to February 15, 1886, in Romney, West Virginia. Established as the Polemic Society of Romney, it became the first organization of its kind in the present-day state of West Virginia, and one of the first in the United States. The society was founded by nine prominent men of Romney with the objectives of advancing literature and science, purchasing and maintaining a library, and improving educational opportunities.
The society debated an extensive range of scientific and social topics, often violating its own rules which banned religious and political subjects. Even though its membership was relatively small, its debates and activities were frequently discussed throughout the Potomac Highlands region, and the organization greatly influenced trends of thought in the Romney community and surrounding areas.

El Tatio is a geothermal field with many geysers located in the Andes Mountains of northern Chile at 4,320 metres (14,170 ft) above mean sea level. It is the third-largest geyser field in the world and the largest in the Southern Hemisphere. Various meanings have been proposed for the name "El Tatio", including "oven" or "grandfather". The geothermal field has many geysers, hot springs, and associated sinter deposits. These hot springs eventually form the Rio Salado, a major tributary of the Rio Loa, and are a major source of arsenic pollution in the river. The vents are sites of populations of extremophile microorganisms such as hyperthermophiles, and El Tatio has been studied as an analogue for the early Earth and possible past life on Mars.
El Tatio lies at the western foot of a series of stratovolcanoes, which runs along the border between Chile and Bolivia. This series of volcanoes is part of the Central Volcanic Zone, one of several volcanic belts in the Andes, and of the Altiplano–Puna volcanic complex (APVC). This is a system of large calderas and associated ignimbrites, which have been the sources of supereruptions between 10 and 1 million years ago. Some of these calderas may be the source of heat for the El Tatio geothermal system. There are no recorded eruptions of the Tatio volcanoes in the historical period. (Full article...)
The Boring Lava Field (also known as the Boring Volcanic Field) is a Plio-Pleistocene volcanic field with cinder cones, small shield volcanoes, and lava flows in the northern Willamette Valley of the U.S. state of Oregon and adjacent southwest Washington. The field got its name from the town of Boring, Oregon, located 12 miles (20 km) southeast of downtown Portland. Boring lies southeast of the densest cluster of lava vents. The zone became volcanically active about 2.7 million years ago, with long periods of eruptive activity interspersed with quiescence. Its last eruptions took place about 57,000 years ago at the Beacon Rock cinder cone volcano; the individual volcanic vents of the field are considered extinct, but the field itself is not.
The Boring Lava Field covers an area of about 1,500 square miles (4,000 km), and has a total volume of 2.4 cubic miles (10 km). This region sustains diverse flora and fauna within its habitat areas, which are subject to Portland's moderate climate with variable temperatures and mild precipitation. The highest elevation of the field is at Larch Mountain, which reaches a height of 4,055 feet (1,236 m). (Full article...)
