The East End of London, often referred to within the London area simply as the East End, is the historic core of wider East London, east of the Roman and medieval walls of the City of London and north of the River Thames. It does not have universally accepted boundaries to the north and east, though the River Lea is sometimes seen as the eastern boundary. Parts of it may be regarded as lying within Central London (though that term too has no precise definition). The term "East of Aldgate Pump" is sometimes used as a synonym for the area.

The East End began to emerge in the Middle Ages with initially slow urban growth outside the eastern walls, which later accelerated, especially in the 19th century, to absorb pre-existing settlements. The first known written record of the East End as a distinct entity, as opposed its component parts, comes from John Strype's 1720 Survey of London, which describes London as consisting of four parts: the City of London, Westminster, Southwark, and "That Part beyond the Tower". The relevance of Strype's reference to the Tower was more than geographical. The East End was the urbanised part of an administrative area called the Tower Division, which had owed military service to the Tower of London since time immemorial. Later, as London grew further, the fully urbanised Tower Division became a byword for wider East London, before East London grew further still, east of the River Lea and into Essex.

Erie (/ˈɪəri/; EER-ee) is a city on the south shore of Lake Erie and the county seat of Erie County, Pennsylvania, United States.

The city was named for the Native American Erie people who lived in the area until the mid-17th century. Erie is the fourth-largest city in Pennsylvania, and the largest city in Northwestern Pennsylvania, with a population of 101,786 at the 2010 census. The estimated population in 2019 had decreased to 95,508. The Erie metropolitan area, equivalent to all of Erie County, consists of 276,207 residents. The Erie-Meadville combined statistical area had a population of 369,331, as of the 2010 Census. (Full article...)

David Alexander Johnston (December 18, 1949 – May 18, 1980) was an American United States Geological Survey (USGS) volcanologist who was killed by the 1980 eruption of Mount St. Helens in the U.S. state of Washington. A principal scientist on the USGS monitoring team, Johnston was killed in the eruption while manning an observation post six miles (10 km) away on the morning of May 18, 1980. He was the first to report the eruption, transmitting "Vancouver! Vancouver! This is it!" before he was swept away by a lateral blast. Despite a thorough search, Johnston's body was never found, but state highway workers discovered remnants of his USGS trailer in 1993.

Johnston's career took him across the United States, where he studied the Augustine Volcano in Alaska, the San Juan volcanic field in Colorado, and long-extinct volcanoes in Michigan. Johnston was a meticulous and talented scientist, known for his analyses of volcanic gases and their relationship to eruptions. This, along with his enthusiasm and positive attitude, made him liked and respected by many co-workers. After his death, other scientists lauded his character, both verbally and in dedications and letters. Johnston felt scientists must do what is necessary, including taking risks, to help protect the public from natural disasters. His work, and that of fellow USGS scientists, convinced authorities to close Mount St. Helens to the public before the 1980 eruption. They maintained the closure despite heavy pressure to re-open the area; their work saved thousands of lives. His story became intertwined with the popular image of volcanic eruptions and their threat to society, and a part of volcanology's history. To date, Johnston, along with Harry Glicken, is one of two American volcanologists known to have died in a volcanic eruption. (Full article...)

The Columbia River (Upper Chinook: Wimahl or Wimal; Sahaptin: Nch’i-Wàna or Nchi wana; Sinixt dialect swah'netk'qhu) is the largest river in the Pacific Northwest region of North America. The river rises in the Rocky Mountains of British Columbia, Canada. It flows northwest and then south into the US state of Washington, then turns west to form most of the border between Washington and the state of Oregon before emptying into the Pacific Ocean. The river is 1,243 miles (2,000 km) long, and its largest tributary is the Snake River. Its drainage basin is roughly the size of France and extends into seven US states and a Canadian province. The fourth-largest river in the United States by volume, the Columbia has the greatest flow of any river entering the Pacific and the 36th greatest of any river in the world.

The Columbia and its tributaries have been central to the region's culture and economy for thousands of years. They have been used for transportation since ancient times, linking the region's many cultural groups. The river system hosts many species of anadromous fish, which migrate between freshwater habitats and the saline waters of the Pacific Ocean. These fish—especially the salmon species—provided the core subsistence for native peoples. (Full article...)

The Southern Cross Expedition, otherwise known as the British Antarctic Expedition, 1898–1900, was the first British venture of the Heroic Age of Antarctic Exploration, and the forerunner of the more celebrated journeys of Robert Falcon Scott and Ernest Shackleton. The brainchild of the Anglo-Norwegian explorer Carsten Borchgrevink, it was the first expedition to over-winter on the Antarctic mainland, the first to visit the Great Ice Barrier—later known as the Ross Ice Shelf—since Sir James Clark Ross's groundbreaking expedition of 1839 to 1843, and the first to effect a landing on the Barrier's surface. It also pioneered the use of dogs and sledges in Antarctic travel.

The expedition was privately financed by the British magazine publisher Sir George Newnes. Borchgrevink's party sailed in the Southern Cross, and spent the southern winter of 1899 at Cape Adare, the northwest extremity of the Ross Sea coastline. Here they carried out an extensive programme of scientific observations, although opportunities for inland exploration were restricted by the mountainous and glaciated terrain surrounding the base. In January 1900, the party left Cape Adare in Southern Cross to explore the Ross Sea, following the route taken by Ross 60 years earlier. They reached the Great Ice Barrier, where a team of three made the first sledge journey on the Barrier surface, during which a new Farthest South record latitude was established at 78° 50′S.

Rwanda, officially the Republic of Rwanda, is a landlocked country in the Great Rift Valley where the African Great Lakes region and East Africa converge. One of the smallest countries on the African mainland, its capital city is Kigali. Located a few degrees south of the Equator, Rwanda is bordered by Uganda, Tanzania, Burundi, and the Democratic Republic of the Congo. It is highly elevated, giving it the soubriquet "land of thousand hills", with its geography dominated by mountains in the west and savanna to the east, with numerous lakes throughout the country. The climate is temperate to subtropical, with two rainy seasons and two dry seasons each year. Rwanda has a population of over 12.6 million living on 26,338 km² (10,169 mi²) of land, and is the most densely populated mainland African country.

The population is young and predominantly rural. Rwandans are drawn from just one cultural and linguistic group, the Banyarwanda, although within this group there are three subgroups: the Hutu, Tutsi and Twa. The Twa are a forest-dwelling pygmy people and are often considered descendants of Rwanda's earliest inhabitants. Scholars disagree on the origins of and differences between the Hutu and Tutsi; some believe differences are derived from former social castes within a single people, while others believe the Hutu and Tutsi arrived in the country separately, and from different locations. Christianity is the largest religion in the country; the principal language is Kinyarwanda, spoken by most Rwandans, with English and French serving as additional official languages. The sovereign state of Rwanda has a presidential system of government. The president is Paul Kagame of the Rwandan Patriotic Front (RPF), who has served continuously since 2000. Today, Rwanda has low levels of corruption compared with neighbouring countries, although human rights organisations report suppression of opposition groups, intimidation and restrictions on freedom of speech. The country has been governed by a strict administrative hierarchy since precolonial times; there are five provinces delineated by borders drawn in 2006. Rwanda is one of only three countries in the world with a female majority in the national parliament, the two other countries being Bolivia and Cuba. (Full article...)

Denbies is a large estate to the northwest of Dorking in Surrey, England. A farmhouse and surrounding land originally owned by John Denby was purchased in 1734 by Jonathan Tyers, the proprietor of Vauxhall Gardens in London, and converted into a weekend retreat. The house he built appears to have been of little architectural significance, but the Gothic garden he developed in the grounds on the theme of death achieved some notoriety, despite being short-lived. The estate was bought by Lord King of Ockham following Tyers' death in 1767, and the macabre artefacts he had installed, including two stone coffins topped by human skulls, were removed.

Joseph Denison, a wealthy banker, purchased the estate in about 1787, and it remained in the Denison family until 1849, when it passed to Thomas Cubitt, a master builder. At the time, Cubitt was working on Osborne House for Queen Victoria and Prince Albert, and the mansion he designed to replace the old one was a more modest version of Osborne. It was still a substantial building though, in the Italianate style, with almost 100 rooms on three storeys. In the nineteenth century Denison and later Cubitt served as local Members of Parliament, for West Surrey. (Full article...)

Kent is a city in the U.S. state of Ohio and the largest city in Portage County. It is located along the Cuyahoga River in Northeast Ohio on the western edge of the county. The population was 28,904 in the 2010 Census and was estimated at 29,646 in 2019. The city is counted as part of the Akron Metropolitan Statistical Area and the larger Cleveland–Akron–Canton Combined Statistical Area.

Part of the Connecticut Western Reserve, Kent was settled in 1805 and was known for many years as Franklin Mills. Settlers were attracted to the area due to its location along the Cuyahoga River as a place for water-powered mills. Later development came in the 1830s and 1840s as a result of the settlement's position along the route of the Pennsylvania and Ohio Canal. Leading up to the American Civil War, Franklin Mills was noted for its activity in the Underground Railroad. With the decline of the canal and the emergence of the railroad, the town became the home of the Atlantic and Great Western Railroad maintenance shops through the influence of Marvin Kent. In 1864 the town was renamed Kent in honor of and in gratitude for Marvin Kent's efforts. It was incorporated as a village in 1867 and became a city after the 1920 Census. Today Kent is a college town best known as the home of the main campus of Kent State University, founded in 1910, and as the site of the 1970 Kent State shootings. (Full article...)

Canberra (/ˈkænbərə/ (listen) KAN-bə-rə)
is the capital city of Australia. Founded following the federation of the colonies of Australia as the seat of government for the new nation, it is Australia's largest inland city and the eighth-largest city overall. The city is located at the northern end of the Australian Capital Territory; 280 km (170 mi) south-west of Sydney and 660 km (410 mi) north-east of Melbourne.

On 1 January 1901, federation of the colonies of Australia was achieved. Section 125 of the new Australian Constitution provided that land, situated in New South Wales and at least 100 miles (160 km) from Sydney, would be ceded to the new federal government. Following discussion and exploration of various areas within New South Wales, the Seat of Government Act 1908 was passed in 1908 which specified a capital in the Yass-Canberra region. The land was transferred to the Commonwealth by New South Wales in 1911, creating the Australian Capital Territory, two years prior to the capital city being founded and formally named as Canberra in 1913.

Allison Guyot (formerly known as Navoceano Guyot) is a tablemount (guyot) in the underwater Mid-Pacific Mountains of the Pacific Ocean. It is a trapezoidal flat mountain rising 1,500 metres above the seafloor to a depth of less than 1,500 m, with a summit platform 35 by 70 kilometres wide. The Mid-Pacific Mountains lie west of Hawaii and northeast of the Marshall Islands, but at the time of their formation were located in the Southern Hemisphere.

The tablemount was probably formed by a hotspot in the present-day Southern Pacific before plate tectonics moved it to its current location. Several hotspots, including the Easter, Marquesas and Society hotspots, may have been involved in the formation of the Mid-Pacific Mountains. Volcanic activity is dated to have occurred circa 111–85 million years ago and formed a volcanic island. Subsequently, carbonate deposition commenced as Allison Guyot subsided and eventually buried the island, forming an atoll-like structure and a carbonate platform. Among other animals, crocodilians lived on Allison Guyot. (Full article...)

The Marshalsea (1373–1842) was a notorious prison in Southwark, just south of the River Thames. Although it housed a variety of prisoners, including men accused of crimes at sea and political figures charged with sedition, it became known, in particular, for its incarceration of the poorest of London's debtors. Over half the population of England's prisons in the 18th century were in jail because of debt.

Run privately for profit, as were all English prisons until the 19th century, the Marshalsea looked like an Oxbridge college and functioned as an extortion racket. Debtors in the 18th century who could afford the prison fees had access to a bar, shop and restaurant, and retained the crucial privilege of being allowed out during the day, which gave them a chance to earn money for their creditors. Everyone else was crammed into one of nine small rooms with dozens of others, possibly for years for the most modest of debts, which increased as unpaid prison fees accumulated. The poorest faced starvation and, if they crossed the jailers, torture with skullcaps and thumbscrews. A parliamentary committee reported in 1729 that 300 inmates had starved to death within a three-month period, and that eight to ten were dying every 24 hours in the warmer weather. (Full article...)

Steller's sea cow (Hydrodamalis gigas) is an extinct sirenian described by Georg Wilhelm Steller in 1741. At that time, it was found only around the Commander Islands in the Bering Sea between Alaska and Russia; its range was more extensive during the Pleistocene epoch, and it is possible that the animal and humans previously interacted. Some 18th-century adults would have reached weights of 8–10 t (8.8–11.0 short tons) and lengths up to 9 m (30 ft).

It was a part of the order Sirenia and a member of the family Dugongidae, of which its closest living relative, the 3 m (9.8 ft) long dugong (Dugong dugon), is the sole living member. It had a thicker layer of blubber than other members of the order, an adaptation to the cold waters of its environment. Its tail was forked, like that of whales or dugongs. Lacking true teeth, it had an array of white bristles on its upper lip and two keratinous plates within its mouth for chewing. It fed mainly on kelp, and communicated with sighs and snorting sounds. Evidence suggests it was a monogamous and social animal living in small family groups and raising its young, similar to modern sirenians. (Full article...)

The Thing is a 1982 American science fiction horror film directed by John Carpenter and written by Bill Lancaster. Based on the 1938 John W. Campbell Jr. novella Who Goes There?, it tells the story of a group of American researchers in Antarctica who encounter the eponymous "Thing", a parasitic extraterrestrial life-form that assimilates, then imitates other organisms. The group is overcome by paranoia and conflict as they learn that they can no longer trust each other and that any one of them could be the Thing. The film stars Kurt Russell as the team's helicopter pilot, R.J. MacReady, and features A. Wilford Brimley, T. K. Carter, David Clennon, Keith David, Richard Dysart, Charles Hallahan, Peter Maloney, Richard Masur, Donald Moffat, Joel Polis, and Thomas G. Waites in supporting roles.

Production began in the mid-1970s as a faithful adaptation of the novella, following 1951's The Thing from Another World. The Thing went through several directors and writers, each with different ideas on how to approach the story. Filming lasted roughly 12 weeks, beginning in August 1981, and took place on refrigerated sets in Los Angeles as well as in Juneau, Alaska, and Stewart, British Columbia. Of the film's $15 million budget, $1.5 million was spent on Rob Bottin's creature effects, a mixture of chemicals, food products, rubber, and mechanical parts turned by his large team into an alien capable of taking on any form.

The siege of Thessalonica between 1422 and 1430 saw the Ottoman Empire under Sultan Murad II capture the city of Thessalonica, which remained in Ottoman hands for the next five centuries, until it became part of the Kingdom of Greece in 1912.

Thessalonica had already been under Ottoman control from 1387 to 1403 before returning to Byzantine rule in the aftermath of the Battle of Ankara. In 1422, after the Byzantines supported Mustafa Çelebi as a rival pretender against him, Murad attacked Thessalonica. Unable to provide manpower or resources for the city's defense, its ruler, Andronikos Palaiologos, handed it over to the Republic of Venice in September 1423. The Venetians attempted to persuade the Sultan to recognize their possession, but failed as Murad considered the city his by right and the Venetians to be interlopers. This impasse led to an Ottoman blockade of Thessalonica, which occasionally flared up with direct attacks on the city. At the same time, the conflict was mostly fought as a series of raids by both sides against the other's territories in the Balkans and the Aegean islands. The Venetians repeatedly tried to apply pressure by blocking the passage of the Dardanelles at Gallipoli, with little success. (Full article...)

Ambohimanga is a hill and traditional fortified royal settlement (rova) in Madagascar, located approximately 24 kilometers (15 mi) northeast of the capital city of Antananarivo. The hill and the rova that stands on top are considered the most significant symbol of the cultural identity of the Merina people and the most important and best-preserved monument of the precolonial Merina Kingdom. The walled historic village includes residences and burial sites of several key monarchs. The site, one of the twelve sacred hills of Imerina, is associated with strong feelings of national identity and has maintained its spiritual and sacred character both in ritual practice and the popular imagination for at least four hundred years. It remains a place of worship to which pilgrims come from Madagascar and elsewhere.

The site has been politically important since the early 18th century, when King Andriamasinavalona (1675–1710) divided the Kingdom of Imerina into four quadrants and assigned his son Andriantsimitoviaminiandriana to govern the northeastern quadrant, Avaradrano, from its newly designated capital at Ambohimanga. The division of Imerina led to 77 years of civil war, during which time the successive rulers of Avaradrano led military campaigns to expand their territory while undertaking modifications to the defenses at Ambohimanga to better protect it against attacks. The war was ended from Ambohimanga by King Andrianampoinimerina, who successfully undertook negotiations and military campaigns that reunited Imerina under his rule by 1793. Upon capturing the historic capital of Imerina at Antananarivo, Andrianampoinimerina shifted his royal court and all political functions back to its original locus at Antananarivo's royal compound and declared the two cities of equal importance, with Ambohimanga as the kingdom's spiritual capital. He and later rulers in his line continued to conduct royal rituals at the site and regularly inhabited and remodeled Ambohimanga until French colonization of the kingdom and the exile of the royal family in 1897. The significance of historical events here and the presence of royal tombs have given the hill a sacred character that is further enhanced at Ambohimanga by the burial sites of several Vazimba, the island's earliest inhabitants.
