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...)

![Image 1 Kigali (Kinyarwanda pronunciation: [ci.ɡɑ́.ɾi]) is the capital and largest city of Rwanda. It is near the nation's geographic centre in a region of rolling hills, with a series of valleys and ridges joined by steep slopes. As a primate city, Kigali is a relatively new city. It has been Rwanda's economic, cultural, and transport hub since it was founded as an administrative outpost in 1907, and became the capital of the country at independence in 1962, shifting focus away from Huye. In an area controlled by the Kingdom of Rwanda from the 15th century, and then, by the German Empire in the beginning of the 20th century, the city was founded in 1907 when Richard Kandt, the colonial resident, chose the site for his headquarters, citing its central location, views and security. Foreign merchants began to trade in the city during the German era, and Kandt opened some government-run schools for Tutsi Rwandan students. Belgium took control of Rwanda and Burundi during World War I, forming the mandate of Ruanda-Urundi. Kigali remained the seat of colonial administration for Rwanda but Ruanda-Urundi's capital was at Usumbura (now Bujumbura) in Burundi and Kigali remained a small city with a population of just 6,000 at the time of independence.

Western Ganga was an important ruling dynasty of ancient Karnataka in India which lasted from about 350 to 1000 CE. They are known as "Western Gangas" to distinguish them from the Eastern Gangas who in later centuries ruled over Kalinga (modern Odisha and Northern Andhra Pradesh). The general belief is that the Western Gangas began their rule during a time when multiple native clans asserted their freedom due to the weakening of the Pallava empire in South India, a geo-political event sometimes attributed to the southern conquests of Samudra Gupta. The Western Ganga sovereignty lasted from about 350 to 550 CE, initially ruling from Kolar and later, moving their capital to Talakadu on the banks of the Kaveri River in modern Mysore district.
After the rise of the imperial Chalukyas of Badami, the Gangas accepted Chalukya overlordship and fought for the cause of their overlords against the Pallavas of Kanchi. The Chalukyas were replaced by the Rashtrakutas of Manyakheta in 753 CE as the dominant power in the Deccan. After a century of struggle for autonomy, the Western Gangas finally accepted Rashtrakuta overlordship and successfully fought alongside them against their foes, the Chola Dynasty of Tanjavur. In the late 10th century, north of Tungabhadra river, the Rashtrakutas were replaced by the emerging Western Chalukya Empire and the Chola Dynasty saw renewed power south of the Kaveri river. The defeat of the Western Gangas by Cholas around 1000 resulted in the end of the Ganga influence over the region. (Full article...)
Underwater diving, as a human activity, is the practice of descending below the water's surface to interact with the environment. It is also often referred to as diving, an ambiguous term with several possible meanings, depending on context.
Immersion in water and exposure to high ambient pressure have physiological effects that limit the depths and duration possible in ambient pressure diving. Humans are not physiologically and anatomically well-adapted to the environmental conditions of diving, and various equipment has been developed to extend the depth and duration of human dives, and allow different types of work to be done.
In ambient pressure diving, the diver is directly exposed to the pressure of the surrounding water. The ambient pressure diver may dive on breath-hold (freediving) or use breathing apparatus for scuba diving or surface-supplied diving, and the saturation diving technique reduces the risk of decompression sickness (DCS) after long-duration deep dives. Atmospheric diving suits (ADS) may be used to isolate the diver from high ambient pressure. Crewed submersibles can extend depth range to full ocean depth, and remotely controlled or robotic machines can reduce risk to humans. (Full article...)
Skegness (/ˌskɛɡˈnɛs/ skeg-NESS) is a seaside town and civil parish in the East Lindsey District of Lincolnshire, England. On the Lincolnshire coast of the North Sea, the town is 43 miles (69 km) east of Lincoln and 22 miles (35 km) north-east of Boston. With a population of 21,128 as of 2021, it is the largest settlement in East Lindsey. It incorporates Winthorpe and Seacroft, and forms a larger built-up area with the resorts of Ingoldmells and Chapel St Leonards to the north. The town is on the A52 and A158 roads, connecting it with Boston and the East Midlands, and Lincoln respectively. Skegness railway station is on the Nottingham to Skegness (via Grantham) line.
The original Skegness was situated farther east at the mouth of The Wash. Its Norse name refers to a headland which sat near the settlement. By the 14th century, it was a locally important port for coastal trade. The natural sea defences which protected the harbour eroded in the later Middle Ages, and it was lost to the sea after a storm in the 1520s. Rebuilt along the new shoreline, early modern Skegness was a small fishing and farming village, but from the late 18th century members of the local gentry visited for holidays. The arrival of the railways in 1873 transformed it into a popular seaside resort. This was the intention of The 9th Earl of Scarbrough, who owned most of the land in the vicinity; he built the infrastructure of the town and laid out plots, which he leased to speculative developers. This new Skegness quickly became a popular destination for holiday-makers and day trippers from the East Midlands factory towns. By the interwar years the town was established as one of the most popular seaside resorts in Britain. The layout of the modern seafront dates to this time and holiday camps were built around the town, including the first Butlin's holiday resort which opened in Ingoldmells in 1936. (Full article...)
The history of Lithuania between 1219 and 1295 concerns the establishment and early history of the first Lithuanian state, the Grand Duchy of Lithuania. The beginning of the 13th century marks the end of the prehistory of Lithuania. From this point on the history of Lithuania is recorded in chronicles, treaties, and other written documents. In 1219, 21 Lithuanian dukes signed a peace treaty with Galicia–Volhynia. This event is widely accepted as the first proof that the Baltic tribes were uniting and consolidating. Despite continuous warfare with two Christian orders, the Livonian Order and the Teutonic Knights, the Grand Duchy of Lithuania was established and gained some control over the lands of Black Ruthenia, Polatsk, Minsk, and other territories east of modern-day Lithuania that had become weak and vulnerable after the collapse of Kievan Rus'.
The first ruler to hold the title of Grand Duke was Mindaugas. Traditionally he is considered the founder of the state, the one who united the Baltic tribes and established the Duchy. Some scholars, however, challenge this perception, arguing that an organized state existed before Mindaugas, possibly as early as 1183. After quelling an internal war with his nephews, Mindaugas was baptized in 1251, and was crowned as King of Lithuania in 1253. In 1261, he broke the peace with the Livonian Order, perhaps even renouncing Christianity. His assassination in 1263 by Treniota ended the early Christian kingdom in Lithuania. For another 120 years Lithuania would remain a pagan empire, fighting against the Teutonic and Livonian Orders during the Northern Crusades during their attempts to Christianize the land.

The Second Silesian War (‹See Tfd›German: Zweiter Schlesischer Krieg) was a war between Prussia and Austria that lasted from 1744 to 1745 and confirmed Prussia's control of the region of Silesia (now in south-western Poland). The war was fought mainly in Silesia, Bohemia, and Upper Saxony and formed one theatre of the wider War of the Austrian Succession. It was the second of three Silesian Wars fought between Frederick the Great's Prussia and Maria Theresa's Austria in the mid-18th century, all three of which ended in Prussian control of Silesia.
The conflict has been viewed as a continuation of the First Silesian War, which had concluded only two years before. After the Treaty of Berlin ended hostilities between Austria and Prussia in 1742, the Habsburg monarchy's fortunes improved greatly in the continuing War of the Austrian Succession. As Austria expanded its alliances with the 1743 Treaty of Worms, Prussia entered a renewed alliance with Austria's enemies in the League of Frankfurt and rejoined the war, hoping to prevent a resurgent Austria from taking back Silesia.

Micronations and the Search for Sovereignty is a 2021 book by Australian constitutional law specialists Harry Hobbs and George Williams about micronations and their legal status. Written from an academic perspective, it is one of few works on micronational movements and the earliest-published book to focus largely on the legal aspect of micronations. The book concerns the definition of statehood, the place of micronations within international law, people's motivations for declaring them, the micronational community and the ways by which such entities mimic sovereign states. In 2022 Hobbs and Williams published a book for a broader audience, How to Rule Your Own Country: The Weird and Wonderful World of Micronations. (Full article...)
Ann Arbor is a college town and the county seat of Washtenaw County, Michigan, United States. The 2020 census recorded its population to be 123,851, making it the fifth-most populous city in Michigan. It is the principal city of the Ann Arbor metropolitan area, which encompasses all of Washtenaw County and had 372,258 residents in 2020. Ann Arbor is also included in the Detroit-Warren-Ann Arbor combined statistical area and the Great Lakes megalopolis.
Ann Arbor was founded in 1824 by John Allen and Elisha Rumsey. It was named after the wives of the village's founders, both named Ann, and the stands of bur oak trees they found at the site of the town. The University of Michigan was established in Ann Arbor in 1837, and the city's population grew at a rapid rate in the early to mid-20th century. (Full article...)
Black Moshannon State Park is a 3,480-acre (1,410 ha) Pennsylvania state park in Rush Township, Centre County, Pennsylvania, United States. It surrounds Black Moshannon Lake, formed by a dam on Black Moshannon Creek, which has given its name to the lake and park. The park is just west of the Allegheny Front, 9 miles (14 km) east of Philipsburg on Pennsylvania Route 504, and is largely surrounded by Moshannon State Forest. A bog in the park provides a habitat for diverse wildlife not common in other areas of the state, such as carnivorous plants, orchids, and species normally found farther north. As home to the "largest reconstituted bog in Pennsylvania", it was chosen by the Pennsylvania Department of Conservation and Natural Resources for its "25 Must-see Pennsylvania State Parks" list.
Humans have long used the Black Moshannon area for recreational, industrial, and subsistence purposes. The Seneca tribe used it as hunting and fishing grounds. European settlers cleared some land for farming, then clear-cut the vast stands of old-growth white pine and eastern hemlock. Black Moshannon State Park rose from the ashes of a depleted forest which had been largely destroyed by wildfire in the years following the lumber era. The forests were rehabilitated by the Civilian Conservation Corps during the Great Depression in the 1930s. Many of the buildings built by the Civilian Conservation Corps stand in the park today and are protected on the list of National Register of Historic Places in three historic districts.

Canberra (/ˈkænbərə/ KAN-bər-ə) 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 Australian city overall. The city is located at the northern end of the Australian Capital Territory at the northern tip of the Australian Alps, the country's highest mountain range. As of June 2023, Canberra's estimated population was 466,566.
The area chosen for the capital had been inhabited by Aboriginal Australians for up to 21,000 years, by groups including the Ngunnawal and Ngambri. European settlement commenced in the first half of the 19th century, as evidenced by surviving landmarks such as St John's Anglican Church and Blundells Cottage. On 1 January 1901, federation of the colonies of Australia was achieved. Following a long dispute over whether Sydney or Melbourne should be the national capital, a compromise was reached: the new capital would be built in New South Wales, so long as it was at least 100 mi (160 km) from Sydney. The capital city was founded and formally named as Canberra in 1913. A plan by the American architects Walter Burley Griffin and Marion Mahony Griffin was selected after an international design contest, and construction commenced in 1913. Unusual among Australian cities, it is an entirely planned city. The Griffins' plan featured geometric motifs and was centred on axes aligned with significant topographical landmarks such as Black Mountain, Mount Ainslie, Capital Hill and City Hill. Canberra's mountainous location makes it the only mainland Australian city where snow-capped mountains can be seen in winter, although snow in the city itself is uncommon. (Full article...)
New South Greenland, sometimes known as Morrell's Land, was an appearance of land recorded by the American captain Benjamin Morrell of the schooner Wasp in March 1823, during a sealing and exploration voyage in the Weddell Sea area of Antarctica. Morrell provided precise coordinates and a description of a coastline which he claimed to have sailed along for more than 300 miles (500 km). Because the Weddell Sea area was so little visited and hard to navigate due to ice conditions, the alleged land was never properly investigated before its existence was emphatically disproven during Antarctic expeditions in the early 20th century.
At the time of Morrell's voyage, the geography of the then-unnamed Weddell Sea and its surrounding coasts was almost entirely unknown, making the claimed sighting initially plausible. However, obvious errors in Morrell's voyage account and his general reputation as a fabulist created scepticism about the existence of this new land. In June 1912, the German explorer Wilhelm Filchner searched for but found no traces of land after his ship Deutschland became icebound in the Weddell Sea and drifted into the locality of Morrell's observation. A line sounding of the sea bottom revealed more than 5,000 feet (1,500 m) of water, indicating no land in near proximity. Three years later, trapped in the same waters with his ship Endurance, Ernest Shackleton was able by similar means to confirm the land's implausibility. (Full article...)
Cleveland is a major city in the U.S. state of Ohio and the county seat of Cuyahoga County. Located along the southern shore of Lake Erie, it is situated across the Canada–United States maritime border and lies approximately 60 mi (97 km) west of Pennsylvania. Cleveland is the most populous city on Lake Erie, the second-most populous city in Ohio, and the 54th-most populous city in the U.S. with a population of 372,624 in 2020. The city anchors the Cleveland metropolitan area, the 33rd-largest in the U.S. at 2.18 million residents, as well as the larger Cleveland–Akron–Canton combined statistical area with 3.63 million residents.
Cleveland was founded in 1796 near the mouth of the Cuyahoga River as part of the Connecticut Western Reserve in modern-day Northeast Ohio by General Moses Cleaveland, after whom the city was named. Its location on the river and the lake shore allowed it to grow into a major commercial and industrial metropolis by the late 19th century, attracting large numbers of immigrants and migrants. It was among the top 10 largest U.S. cities by population for much of the 20th century, a period that saw the development of the city's cultural institutions. By the 1960s, Cleveland's economy began to slow down as manufacturing declined and suburbanization occurred. (Full article...)
