Yamaguchi Prefecture

Yamaguchi Prefecture (山口県) is a prefecture of Japan located in the Chūgoku region of Honshu. Yamaguchi Prefecture has a population of 1,377,631 (1 February 2018) and has a geographic area of 6,112 km2 (2,359 sq mi). Yamaguchi Prefecture borders Shimane Prefecture to the north and Hiroshima Prefecture to the northeast.

Yamaguchi is the capital and Shimonoseki is the largest city of Yamaguchi Prefecture, with other major cities including Ube, Shūnan, and Iwakuni. Yamaguchi Prefecture is located at the western tip of Honshu with coastlines on the Sea of Japan and Seto Inland Sea, and separated from the island of Kyushu by the Kanmon Straits.

History
Yamaguchi Prefecture was created by the merger of the provinces of Suō and Nagato. During the rise of the samurai class during the Heian and Kamakura Periods (794–1333), the Ouchi family of Suō Province and the Koto family of Nagato Province gained influence as powerful warrior clans. In the Muromachi period (1336—1573), Ouchi Hiroyo, the 24th ruler of the Ouchi family conquered both areas of Yamaguchi Prefecture. The Ouchi clan imitated the city planning of Kyoto. They gained great wealth through cultural imports from the continent and trade with Korea and Ming Dynasty China. As a result, Yamaguchi came to be known as the "Kyoto of the West," and Ouchi culture flourished. Sue Harutaka defeated the 31st ruler of the Ouchi clan. The Sue clan was then defeated by Mōri Motonari, and the Mōri family gained control of the Chūgoku region. Yamaguchi was ruled as part of the Mōri clan domain during the Sengoku period. Mōri Terumoto was then defeated by Tokugawa Ieyasu in the battle of Sekigahara in 1600. He was forced to give up all his land except for the Suō and Nagato areas (current-day Yamaguchi Prefecture), where he built his castle in Hagi. Mōri sought to strengthen the economic base of the region and increase local production with his Three Whites campaign (salt, rice, and paper).

After Commodore Matthew Perry's opening of Japan, clans from Nagato (also called Chōshū) played a key role in the fall of the Tokugawa shogunate and the establishment of the new imperial government. Four years after the Edo Shogunate was overthrown and the Meiji government formed in 1868, the present Yamaguchi Prefecture was established. The Meiji government brought in many new systems and modern policies, and promoted the introduction of modern industry, though the prefecture was still centered on agriculture during this period. In the Taishō period, from 1912 to 1926, shipbuilding, chemical, machinery, and metal working plants were built in Yamaguchi's harbors in the Seto Inland Sea area. During the post-World War II Shōwa Period, Yamaguchi developed into one of the most industrialized prefectures in the country due to the establishment of petrochemical complexes.

Geography
As of April 1, 2012, 7% of the total land area of the prefecture was designated as Natural Parks, namely the Setonaikai National Park; Akiyoshidai, Kita-Nagato Kaigan, and Nishi-Chūgoku Sanchi Quasi-National Parks; and Chōmonkyō, Iwakiyama, Rakanzan, and Toyota Prefectural Natural Parks.

Economic development
For the purposes of development analysis, Yamaguchi is construed to be part of Northern Kyushu. Although Yamaguchi is not part of the island of Kyushu, it has become a functional satellite of the Kanmon Straits metropolitan area.

Demographics
Per Japanese census data, Yamaguchi prefecture has had negative population growth from 1955 to 1973 and 1985–onwards, today at edge of having less than 1940 population leaving elderly behind.

Tourism
The most popular place for tourism is Shimonoseki, which has the Karato Fish Market and a large fireworks festival in summer.

Another attraction is the Kintai Bridge in the town of Iwakuni. This five-arched wooden structure is considered a symbol of Western Honshū. The area on the banks of the Nishiki river close to the bridge is considered among the best places in Japan for Hanami, when groups of family and friends gather in early April to view cherry blossoms.

Hagi City is in the north of Yamaguchi. It is a very traditional city. The usual color of Japanese post boxes is red, but in Hagi they are painted green or brown. The Hagi Museum is modeled after a traditional samurai residence. The exhibits are detailed and realistic, and are changed every year. The permanent collection is data about Hagi's history and collections about Takasugi Shinsaku. Hagi also contains a reverberatory furnace which has been designated a World Heritage Site.

Kawara soba (hot tile noodles) is a popular dish in Yamaguchi. It was developed during the Seinan Rebellion when soldiers cooked wild grass and meat on hot tiles. Today people in Yamaguchi create this dish by frying green tea noodles on a hot tile, and arranging a thin fried egg, stewed beef, green onions, and grilled liver on top.

Akiyoshidai Quasi-National Park, which includes Japan's longest cave, the Akiyoshido (秋芳洞), is another popular destination.

Politics
Since the Meiji Restoration in which lower-rank nobility from Chōshū played a major role, many politicians from Yamaguchi have held important positions in national politics. In the post-war era, the most prominent political family from Yamaguchi is the Kishi-Abe/Satō prime ministerial dynasty, and Yamaguchi is leaning solidly towards the Liberal Democratic Party (LDP).

Delegation to the National Diet
Since the electoral reform of the 1990s, Yamaguchi elects four members directly to the House of Representatives. Three of the new single-member districts have been held exclusively by Liberal Democrats as of 2013, the easternmost district bordering Hiroshima was initially won by Shinji Satō (Eisaku Satō's son) in 1996, but went to Democrat Hideo Hiraoka in several later elections. Currently, following the 2021 general election, Yamaguchi's directly elected delegation to the lower house consists of former LDP vice president Masahiko Kōmura (1st district, 12th term), the chairman of the foreign affairs committee, Nobuo Kishi (2nd district, 2nd term, former two-term member of the House of Councillors), and the chairman of the House of Representatives rules committee (as of 190th Diet, January 2016), Yoshimasa Hayashi (3rd district, 1st term). The seat for the 4th district was held by former prime minister Shinzo Abe until his assassination in 2022, and is currently vacant. For the proportional representation segment of the House of Representatives, Yamaguchi forms part of the Chūgoku block.

In the House of Councillors, Yamaguchi is represented by two members, making it one of the currently 31 winner-take-all single-member districts. As of 2013, the two members are Yoshimasa Hayashi (LDP, 4th term, up in 2019), agriculture minister in the 2nd Abe Cabinet, and following the April 2013 by-election to replace Nobuo Kishi, Kiyoshi Ejima (LDP, 1st term, up in 2016), former mayor of Shimonoseki city.

Governor
The current governor of Yamaguchi is former MIC bureaucrat Tsugumasa Muraoka. He won the gubernatorial election in February 2014 with more than 60% of the vote against other two candidates, and succeeded Shigetarō Yamamoto who had been hospitalized since October 2013 and resigned in January 2014.

Jelly Babies

Jelly Babies are a type of soft sugar jelly sweets in the shape of plump babies, sold in a variety of colours. They were first manufactured in Lancashire, England, in the nineteenth century. Their popularity waned before being revived by Bassett's of Sheffield in Yorkshire, who began mass-producing Jelly Babies (initially sold as "Peace Babies") in 1918.

History
"Jelly Babies" are known at least since advertisements by Riches Confectionery Company of 22 Duke Street, London Bridge in 1885, along with a variety of other baby sweets, including "Tiny Totties" and "Sloper’s Babies". But the pricing of these, at one farthing each, suggests that they were very much larger than the modern Jelly Baby.

The sweets were invented in 1864 by an Austrian immigrant working at Fryers of Lancashire, and were originally marketed as "Unclaimed Babies". By 1918 they were produced by Bassett's in Sheffield as "Peace Babies", to mark the end of World War I. Bassett's themselves have supported the "Peace Babies" name. Production was suspended during World War II due to wartime shortages. The product was relaunched as "Jelly Babies" in 1953.

A line of sweets called Jellyatrics was launched by Barnack Confectionery Ltd to commemorate the "Jelly Baby’s 80th Birthday" in March 1999. Jellyatrics celebrate "all that is great and good about the older generation".

Manufacture
The most noted modern manufacturer of Jelly Babies, Bassett's, now allocate individual name, shape, colour and flavour to different babies: Brilliant (red; strawberry), Bubbles (yellow; lemon), Baby Bonny (pink; raspberry), Boofuls (green; lime), Bigheart (purple; blackcurrant), and Bumper (orange).

The introduction of different shapes and names was an innovation, circa 1989, prior to which all colours of jelly baby were a uniform shape. Bassett's Jelly Babies changed in September 2007 to include only natural colours and ingredients. There are many brands of jelly babies, as well as supermarket own brands.

Jelly Babies manufactured in the United Kingdom tend to be dusted in starch, which is left over from the manufacturing process, where it is used to aid release from the mould. Jelly Babies manufactured in Australia generally lack this coating. Like most other gummy sweets, they contain gelatin.

In popular culture
In October 1963, as Beatlemania was breaking out, fans of The Beatles in the United Kingdom pelted the band with jelly babies (or, in the United States, the much harder jelly beans) after it was reported that George Harrison liked eating them.

Beginning in the Second Doctor era of the popular British science fiction television series Doctor Who, but especially during that of Tom Baker's Fourth Doctor, jelly babies were frequently featured as a plot device in which the Doctor would attempt to ease an awkward moment or prevent potential conflict with an unfamiliar being by offering, "would you like a jelly baby?"

In the series by Terry Pratchett, Discworld, the country of Djelibeybi (a pun on "jelly baby", but putatively meaning "Child of the (River) Djel", and possibly derived from Djellaba), is the Discworld's analogue of Ancient Egypt. The main setting of Pyramids, Djelibeybi is about two miles (3200 m) wide, along the 150-mile (240 km) length of the Djel.

Australian singer, Alison Hams, released the "Jelly Baby Song" in May 2013 – its content alluding to the consumption of jelly babies by Type 1 Diabetics to overcome hypoglycaemic episodes – as a way to raise awareness for Type 1 Diabetes, for JDRF Australia (Juvenile Diabetes Research Foundation) who sell specially packaged jelly babies, as the focus of their annual campaign "Jelly Baby Month".

A popular school chemistry experiment, is to put them in a strong oxidising agent, and see the resulting spectacular reaction. The experiment is commonly referred to as "screaming jelly babies".

A poll of 4,000 adults in Britain voted jelly babies their sixth favourite sweet in August 2009. Jelly Babies are the favourite snack of Basil Brush, a British fox puppet.

In the 2018 film Johnny English Strikes Again, the titular character (played by Rowan Atkinson) carries a box of jelly babies with him, but they are actually disguised explosives, as in said context, "jelly" is actually short for gelignite, and they blow up whomever eats them.

Dimitrie Cantemir

Dimitrie or Demetrius Cantemir (, Дмитрий Кантемир; 26 October 1673 – 21 August 1723), also known by other spellings, was a Moldavian prince, statesman, and man of letters. He twice served as voivode of Moldavia (March–April 1693 and 1710–1711). During his second term he allied his state with Russia in a war against Moldavia's Ottoman overlords; Russia's defeat forced Cantemir's family into exile and the replacement of the native voivodes by Greek phanariots. Cantemir was also a prolific writer, variously a philosopher, historian, composer, musicologist, linguist, ethnographer, and geographer. His son Antioch, Russia's ambassador to Great Britain and France and a friend of Montesquieu and Voltaire, would become known as "the father of Russian poetry".

Name
Dimitrie is the Romanian form of the name Latinized as Demetrius and, less often, anglicized as Demeter. The Russian form of his name was Dmitri Konstantinovich Kantemir (Дми́трий Константи́нович Кантеми́р). He is also known as Dimitri Kantemiroğlu in Turkish contexts, Dymitr Kantemir in Polish, and Dēmētrios Kantimērēs (Δημήτριος Καντιμήρης) in Greek. His surname Cantemir (Kantemir) is of Turkic/Tatar origin, "kan" meaning "blood" and "temir" meaning "iron".

Life
Dimitrie was born in Silişteni, Moldavia (now Vaslui County, Romania) on 26 October 1673 to Constantin Cantemir and Ana Bantăș. His mother was a learned daughter of a local noble family. In 1685, Constantin was named voivode of Moldavia by its Turkish overlords.

Although Constantin himself was illiterate, he educated his sons Dimitrie and Antioh thoroughly. Dimitrie learned Greek and Latin to read the classics as a child. One of his tutors was the scholar John Komnenos Molyvdos. Between 1687 and 1710, Dimitrie spent most of his time as a hostage or envoy in Constantinople, living in the palace he owned, where he learned Turkish and studied Ottoman history at the Patriarchate's Greek Academy. While there, he also composed Ottoman music.

Upon Constantin's death in 1693, Dimitrie briefly succeeded him to the voivodeship but was passed over within three weeks in favor of Constantin Duca, whose candidacy was supported by his father-in-law, the Wallachian voivode Constantin Brâncoveanu. When his brother Antioh eventually succeeded to the control of Moldavia, Dimitrie served as his envoy to the Porte. During these years, he also served with distinction in the Turkish army on its campaigns.

In 1710, Dimitrie was appointed voivode in his own right. Believing Ottoman Turkey to be collapsing, he placed Moldavia under Russian control through a secret agreement signed at Lutsk. Then he joined Peter the Great in his war against the Turks. This ended in failure at Stănilești (18–22 July 1711) and the Cantemirs were forced into Russian exile. Turkey then replaced the voivodeship with the rule of Greek phanariots. In 1712, Peter I presented Bogorodskoye District (Black Mud) to the former Moldavian ruler.

In Russia, Dimitrie was created both a Russian prince (knyaz) by Peter and a prince of the Holy Roman Empire by Charles VI. He lived on an estate at Dmitrovka near Oryol, with a sizable boyar retinue (including the chronicler Ion Neculce). There he died on 21 August 1723, on the very day he was awarded his German title. In 1935, his remains were returned to Iași.

Family
Cantemir was married twice: to Princess Cassandra Cantacuzino (1682–1713), daughter of Prince Șerban Cantacuzino and supposed descendant of the Byzantine Kantakouzenoi, in 1699, and to Princess Anastasiya Trubetskaya (1700–1755) in 1717. Cantemir's children were rather prominent in Russian history. His elder daughter Maria Cantemir (1700–1754) so attracted Peter the Great that he allegedly planned to divorce his wife Catherine to be with her. Upon Catherine's own ascension to the throne, however, Maria was forced to enter a convent. Cantemir's son Antioch (1708–1744) was the Russian ambassador at London and Paris, a friend of Voltaire and Montesquieu, and so influential a poet, satirist, and essayist as to be considered "the father of Russian poetry". Another son Constantin (1703–1747) was implicated in the Golitsyn conspiracy against the empress Anna and was exiled to Siberia. Dimitrie's younger daughter Smaragda (1720–1761), reckoned one of the great beauties of her time, was the wife of Prince Dmitriy Mikhailovich Golitsyn and a friend of the empress Elizabeth.

Historical works
Cantemir was a polyglot known as one of the greatest linguists of his time, speaking and writing eleven languages. Well versed in Oriental scholarship, his oeuvre is voluminous, diverse, and original, although some of his scientific writings contain unconfirmed theories or simple inaccuracies. Between 1711 and 1719 he wrote his most important creations. In 1714, he was named a member of the Royal Academy of Berlin.

Cantemir's best-known history work was his History of the Growth and Decay of the Ottoman Empire (the original title was in Latin, Historia incrementorum atque decrementorum Aulae Othomanicae ). This volume circulated throughout Europe in manuscript for a number of years. It was finally printed in 1734 in London and was later translated and printed in Germany and France. It remained the seminal work on the Ottoman Empire up to the middle of the 19th century; notably, it was used as a reference for Edward Gibbon's own Decline and Fall of the Roman Empire. Later scholarship contests many points owing to the dubiousness of some of Cantemir's sources.

He also published the first critical history of Romania as a whole, the Chronicle of the Antiquity of the Romano-Moldavo-Wallachians (Hronicul vechimei a romano-moldo-vlahilor), from 1719 to 1722. It asserted the Latin origin of the Romanian language and the Roman origin of the people living within the former land of Dacia.

Cantemir wrote his Descriptio Moldaviae ("Description of Moldavia" in Latin) in 1714 at the request of the Royal Academy in Berlin. Covering geographical, ethnographical, and economic aspects of Moldavia, it was similarly circulated in manuscript and only published much later. It appeared in a German geographical magazine in 1769 and was published as a book in 1771. His c. 1714 manuscript map of Moldova was the first real map of the country, containing geographical detail as well as administrative information. Printed in 1737 in the Netherlands, it formed the basis of most European maps of the country for decades.

His 1705 roman à clef A Hieroglyphic History was the first Romanian novel, representing the history of the Wallachian Brâncoveanu and Cantacuzino dynasties through allegorical and mythological animals.

He also wrote an introduction to Islam for Europeans, a biography of Jan Baptist van Helmont, a philosophical treatise in Romanian and Greek,  and an unfinished second treatise on the Undepictable Image of Sacred Science.

Due to his many esteemed works he won great renown at the high courts of Europe. His name is among those who were considered to be the brightest minds of the world on a plaque at the Library of Sainte-Genevieve in Paris, next to those of Leibniz, Newton, Piron, and other great thinkers.

Musical works
A few of Cantemir's roughly forty Ottoman compositions are still performed today as part of the Turkish repertoire, but his greatest service was in preserving 350 traditional instrumental pieces by publishing them in a musical notation he developed from the Ottoman Turkish alphabet in his work Edvar-i Musiki, offered as a present to Sultan Ahmed III in 1703 or 1704 and recently reprinted with modern explanations.

In 1999, the Bezmara ensemble recorded Yitik Sesin Peşinde ("In Search of the Lost Sound") from the Cantemir transcriptions using period instruments. His compositions, those of his European contemporaries and Moldavian folk music of the period were explored on Cantemir (Golden Horn Records, 2000) performed by İhsan Özgen and the Lux Musica ensemble under Linda Burman-Hall's direction. Seven of Cantemir's compositions were also featured on Hespèrion XXI's 2009 Istanbul, under the direction of Jordi Savall, with focus on Cantemir's “Book of the Science of Music”.

Istanbul Museum
One of the houses inhabited by Dimitrie Cantemir during his exile in Constantinople was restored and opened as a museum in 2007. It lies in Fener quarter of the walled city between Phanar College and the Golden Horn.

Namib

The Namib (Namibe) is a coastal desert in Southern Africa. According to the broadest definition, the Namib stretches for more than 2000 km along the Atlantic coasts of Angola, Namibia, and northwest South Africa, extending southward from the Carunjamba River in Angola, through Namibia and to the Olifants River in Western Cape, South Africa. The Namib's northernmost portion, which extends 450 km from the Angola-Namibia border, is known as Moçâmedes Desert, while its southern portion approaches the neighboring Kalahari Desert. From the Atlantic coast eastward, the Namib gradually ascends in elevation, reaching up to 200 km inland to the foot of the Great Escarpment. Annual precipitation ranges from 2 mm in the aridest regions to 200 mm at the escarpment, making the Namib the only true desert in southern Africa. Having endured arid or semi-arid conditions for roughly 55–80 million years, the Namib may be the oldest desert in the world and contains some of the world's driest regions, with only western South America's Atacama Desert to challenge it for age and aridity benchmarks.

The desert geology consists of sand seas near the coast, while gravel plains and scattered mountain outcrops occur further inland. The sand dunes, some of which are 300 m high and span 32 km long, are the second-largest in the world after the Badain Jaran Desert dunes in China. Temperatures along the coast are stable and generally range between 9 - 20 °C annually, while temperatures further inland are variable—summer daytime temperatures can exceed 45 °C while nights can be freezing. Fogs that originate offshore from the collision of the cold Benguela Current and warm air from the Hadley Cell create a fog belt that frequently envelops parts of the desert. Coastal regions can experience more than 180 days of thick fog a year. While this has proved a major hazard to ships—more than a thousand wrecks litter the Skeleton Coast—it is a vital source of moisture for desert life.

The Namib is almost completely uninhabited by humans except for several small settlements and indigenous pastoral groups, including the Ovahimba and Obatjimba Herero in the north, and the Topnaar Nama in the central region. Owing to its antiquity, the Namib may be home to more endemic species than any other desert in the world. Most of the desert wildlife is arthropods and other small animals that live on little water, although larger animals inhabit the northern regions. Near the coast, the cold ocean water is rich in fishery resources and supports populations of brown fur seals and shorebirds, which serve as prey for the Skeleton Coast's lions. Further inland, the Namib-Naukluft National Park supports population of mountain zebras, and other large mammals. Further north near the Skeleton Coast, lions, elephants and rhinos can be found. Although the outer Namib is largely barren of vegetation, lichens and succulents are found in coastal areas, while grasses, shrubs, and ephemeral plants thrive near the escarpment. Several types of trees are also able to survive the extremely arid climate.

Etymology
The name Namib is of Khoekhoegowab (or Nama language) origin, and has been variously reported to mean "vast place" and "an area where there is nothing".

Geography and geology
The Namib Desert is one of the 500 distinct physiographic provinces of the South African Platform physiographic division. It occupies an area of around 80,950 km2, stretching from the Uniab River (north) to the town of Lüderitz (south) and from the Atlantic Ocean (west) to the Namib Escarpment (east). It is about 1,000 mi long from north to south and its east–west width varies from 30 to 100 mi. To the north, the desert leads into the Kaokoveld; the dividing line between these two regions is roughly at the latitude of the city of Walvis Bay, and it consists in a narrow strip of land (about 50 km wide) that is the driest place in Southern Africa. To the south, the Namib borders the South African Karoo semi-desert.

Southern Namib (between Lüderitz and the Kuiseb River) comprises a vast dune sea with some of the tallest and most spectacular dunes in the world, ranging in color from pink to vivid orange. In the Sossusvlei area, several dunes exceed 300 m in height. The complexity and regularity of dune patterns in its dune sea have attracted the attention of geologists for decades, but it remains poorly understood.

The source of the unconsolidated sand (the most recent sand sea) is dominantly from the Orange River, which drains into the Atlantic south of the Namib Sand Sea, with minor contributions in the east from the (now ephemeral) rivers that drain into the sand sea. For this reason, the Namib Sand Sea has been referred to as the "wind displaced delta of the Orange River."

Moving north from Sossusvlei, the sand gradually gives way to a rocky desert that extends from Sossusvlei to the Swakop river. This area is traversed by the Tropic of Capricorn and is mostly flat, although some scenic canyons and elevations are found in some areas, for example in the Moon Valley system. While most of the soil is rocky, sand dunes are still occasionally found in this region; for example, sand dunes occupy much of the coastline between Walvis Bay and Swakopmund.

The Namib desert is an important location for the mining of tungsten, salt, and diamonds.

Several rivers and streams run through the Namib, although all of the rivers south of the Cunene River and north of the Orange River are ephemeral and rarely or never reach the ocean. These rivers arise in the interior mountains of Namibia and flow after summer rain storms.

Climate
The Namib's aridity is caused by the descent of dry air of the Hadley cell, cooled by the cold Benguela Current along the coast. It has less than 10 mm of rain annually and is almost completely barren. Besides rain being scarce, it is also unpredictable. Western Namib gets less rain (5 mm) than eastern Namib (85 mm). This is due to several factors. Winds coming from the Indian Ocean lose part of their humidity when passing the Drakensberg mountains, and are essentially dry when they reach the Namib Escarpment at the eastern end of the desert. On the other hand, winds coming from the Atlantic Ocean are pressed down by hot air from the east; their humidity thus forms clouds and fog. Morning fogs coming from the ocean and pushing inwards into the desert are a regular phenomenon along the coast, and much of the life cycle of animals and plants in the Namib relies on these fogs as the main source of water. The dry climate of Namib reflects the almost complete lack of bodies of water on the surface. Most rivers flow underground and/or are dry for most of the year. Even when they are not, they usually drain into endorheic basins, without reaching the sea. The Swakop and the Omaruru are the only rivers that occasionally drain into the ocean. All along the coast, but mostly in the northernmost part of it, the interaction between the water-laden air coming from the sea via southerly winds, some of the strongest of any coastal desert, and the dry air of the desert causes immense fogs and strong currents. It causes sailors to lose their way; this is testified by the remnants of several shipwrecks that can be found along the Skeleton Coast, in northern Namib. Some of these wrecked ships can be found as much as 50 m inland, as the desert slowly moves westwards into the sea, reclaiming land over many years. Benguela's El Niño (similar to the Pacific event in its environmental change in the seas) spreads from the Kunene estuary southward to, on occasion, south of Luderitz. Warm waters with depth and associated water flow from the northwest were first fully catalogued by Sea Fisheries researchers, in Cape Town (L V Shannon et al.). The research noted the positive effect of Benguela's El Niño on the rainfall of the interior. Rainfall records also show positive values variously across the Namib, Desert Research Station, and Gobabeb for instance. This event recurs approximately mid-decade (recent examples are 1974, 1986, 1994, 1995, and 2006).

Flora
Several unusual species of plants and animals are found in this desert, many of which are endemic and highly adapted to the specific climate of the area.

One of the most well-known endemic plants of the Namib is the bizarre Welwitschia mirabilis; a shrub-like plant, it grows two long strap-shaped leaves continuously throughout its lifetime. These leaves may be several meters long, gnarled, and twisted from the desert winds. The taproot of the plant develops into a flat, concave disc in age. Welwitschia is notable for its survival in the extremely arid Namib conditions, made possible by its ability to capture moisture from coastal sea fogs. Areas where Welwitschias are a common sight include the eponymous Welwitschia Plains, which are adjacent to the Husab uranium mine, one of the largest of its kind in the world.

"Fairy circles", which are circular patches of land barren of plants, varying between 22 and 12 m in diameter and often encircled by a ring of stimulated growth of grass, are found in the Namib, such as those near the Wolwedans desert camp.

Fauna

The Namib fauna mostly comprises arthropods and other small animals that can live on little water, but a few species of bigger animals are also found, including antelopes (such as gemsboks and springboks), ostriches, and in some areas even desert elephants or lions. All these species have developed techniques to survive in the Namib environment. Several endemic darkling beetles species have different methods of collecting water droplets from morning fog; they are collectively known as "fog beetles". For example, one beetle, Onymacris unguicularis, has smooth elytrons that cause humidity from the morning fogs to condense into droplets, which roll down the beetle's back to its mouth. Another beetle, the Lepidochora discoidalis, builds "water-capturing" webs. Black-backed jackals lick humidity from stones. Gemsboks (also known as the South African oryx) can raise the temperature of their bodies to 40 °C in the hottest hours of the day. The desert is also home to meerkats and several species of lizards.

Human activity
Before the 20th century, some San roamed the Namib, gathering edible plants on the shore, hunting in the interior, and drinking the juice of the tsamma melon for water. Today, some Herero still herd their livestock in the Kaokoveld in the Namib and take them from waterhole to waterhole. A few Nama Khoikhoi still graze their livestock on the banks of the Kuiseb River in the desert. Most of the native people have left, leaving the vast majority of the desert uninhabited.

The steppes in the southern half of the desert are mostly made up of ranches run by Europeans, who raise Karakul sheep with local help and send the pelts of the lambs to Europe for use in fur coats. Most of the rest of the desert is set aside for conservation. A vast portion of the desert, called the Sperrgebiet, was access-restricted due to the presence of diamonds, which are mined in the area at the mouth of the Orange River. Although the desert is largely unpopulated and inaccessible, there are year-round settlements at Sesriem, close to the Sossusvlei area, and other small outposts in other locations. Moçâmedes in Angola, and Lüderitz, Walvis Bay, and Swakopmund in Namibia, bordering on the desert, are the main settlements in the area.

The 2015 film Mad Max: Fury Road was filmed here.

In 2019 the Namibian-German artist Max Siedentopf created an installation in the Namib consisting of a ring of large white blocks atop of which sit six speakers attached to a solar-powered MP3 player configured to continuously play the 1982 song "Africa" by the American band Toto. The exact location of the installation has not been disclosed.

Namib-Naukluft National Park
The Namib-Naukluft National Park, which extends over a large part of the Namib Desert, is the largest game reserve in Africa and one of the largest in the world. While most of the park is hardly accessible, several well-known visitor attractions are found in the desert. The prominent attraction is the Sossusvlei area, where high orange sand dunes surround vivid white salt pans, creating a fascinating landscape.

Access to the park is either by gravel roads or dust roads (except for 60 km of concrete road from the Sesriem gate to Sossusvlei) or by light aircraft from Windhoek (the capital of Namibia, about 480 km northeast of the centre of the desert), or Swakopmund and Walvis Bay at the north end of the desert.

Galaxy rotation curve

The rotation curve of a disc galaxy (also called a velocity curve) is a plot of the orbital speeds of visible stars or gas in that galaxy versus their radial distance from that galaxy's centre. It is typically rendered graphically as a plot, and the data observed from each side of a spiral galaxy are generally asymmetric, so that data from each side are averaged to create the curve. A significant discrepancy exists between the experimental curves observed, and a curve derived by applying gravity theory to the matter observed in a galaxy. Theories involving dark matter are the main postulated solutions to account for the variance.

The rotational/orbital speeds of galaxies/stars do not follow the rules found in other orbital systems such as stars/planets and planets/moons that have most of their mass at the centre. Stars revolve around their galaxy's centre at equal or increasing speed over a large range of distances. In contrast, the orbital velocities of planets in planetary systems and moons orbiting planets decline with distance according to Kepler’s third law. This reflects the mass distributions within those systems. The mass estimations for galaxies based on the light they emit are far too low to explain the velocity observations.

The galaxy rotation problem is the discrepancy between observed galaxy rotation curves and the theoretical prediction, assuming a centrally dominated mass associated with the observed luminous material. When mass profiles of galaxies are calculated from the distribution of stars in spirals and mass-to-light ratios in the stellar disks, they do not match with the masses derived from the observed rotation curves and the law of gravity. A solution to this conundrum is to hypothesize the existence of dark matter and to assume its distribution from the galaxy's center out to its halo.

Though dark matter is by far the most accepted explanation of the rotation problem, other proposals have been offered with varying degrees of success. Of the possible alternatives, one of the most notable is modified Newtonian dynamics (MOND), which involves modifying the laws of gravity.

History
In 1932, Jan Hendrik Oort became the first to report that measurements of the stars in the solar neighborhood indicated that they moved faster than expected when a mass distribution based upon visible matter was assumed, but these measurements were later determined to be essentially erroneous. In 1939, Horace Babcock reported in his PhD thesis measurements of the rotation curve for Andromeda which suggested that the mass-to-luminosity ratio increases radially. He attributed that to either the absorption of light within the galaxy or to modified dynamics in the outer portions of the spiral and not to any form of missing matter. Babcock's measurements turned out to disagree substantially with those found later, and the first measurement of an extended rotation curve in good agreement with modern data was published in 1957 by Henk van de Hulst and collaborators, who studied M31 with the newly commissioned Dwingeloo 25 meter telescope. A companion paper by Maarten Schmidt showed that this rotation curve could be fit by a flattened mass distribution more extensive than the light. In 1959, Louise Volders used the same telescope to demonstrate that the spiral galaxy M33 also does not spin as expected according to Keplerian dynamics.

Reporting on NGC 3115, Jan Oort wrote that "the distribution of mass in the system appears to bear almost no relation to that of light... one finds the ratio of mass to light in the outer parts of NGC 3115 to be about 250". On page 302–303 of his journal article, he wrote that "The strongly condensed luminous system appears imbedded in a large and more or less homogeneous mass of great density" and although he went on to speculate that this mass may be either extremely faint dwarf stars or interstellar gas and dust, he had clearly detected the dark matter halo of this galaxy.

The Carnegie telescope (Carnegie Double Astrograph) was intended to study this problem of Galactic rotation.

In the late 1960s and early 1970s, Vera Rubin, an astronomer at the Department of Terrestrial Magnetism at the Carnegie Institution of Washington, worked with a new sensitive spectrograph that could measure the velocity curve of edge-on spiral galaxies to a greater degree of accuracy than had ever before been achieved. Together with fellow staff-member Kent Ford, Rubin announced at a 1975 meeting of the American Astronomical Society the discovery that most stars in spiral galaxies orbit at roughly the same speed, and that this implied that galaxy masses grow approximately linearly with radius well beyond the location of most of the stars (the galactic bulge). Rubin presented her results in an influential paper in 1980. These results suggested either that Newtonian gravity does not apply universally or that, conservatively, upwards of 50% of the mass of galaxies was contained in the relatively dark galactic halo. Although initially met with skepticism, Rubin's results have been confirmed over the subsequent decades.

If Newtonian mechanics is assumed to be correct, it would follow that most of the mass of the galaxy had to be in the galactic bulge near the center and that the stars and gas in the disk portion should orbit the center at decreasing velocities with radial distance from the galactic center (the dashed line in Fig. 1).

Observations of the rotation curve of spirals, however, do not bear this out. Rather, the curves do not decrease in the expected inverse square root relationship but are "flat", i.e. outside of the central bulge the speed is nearly a constant (the solid line in Fig. 1). It is also observed that galaxies with a uniform distribution of luminous matter have a rotation curve that rises from the center to the edge, and most low-surface-brightness galaxies (LSB galaxies) have the same anomalous rotation curve.

The rotation curves might be explained by hypothesizing the existence of a substantial amount of matter permeating the galaxy outside of the central bulge that is not emitting light in the mass-to-light ratio of the central bulge. The material responsible for the extra mass was dubbed dark matter, the existence of which was first posited in the 1930s by Jan Oort in his measurements of the Oort constants and Fritz Zwicky in his studies of the masses of galaxy clusters. The existence of non-baryonic cold dark matter (CDM) is today a major feature of the Lambda-CDM model that describes the cosmology of the universe.

Halo density profiles
In order to accommodate a flat rotation curve, a density profile for a galaxy and its environs must be different than one that is centrally concentrated. Newton's version of Kepler's Third Law implies that the spherically symmetric, radial density profile $ρ(r)$ is: $$\rho(r) = \frac{v(r)^2 }{4 \pi G r^2}\left(1+2~ \frac{d\log v(r)}{d\log r}\right) $$ where $v(r)$ is the radial orbital velocity profile and $G$ is the gravitational constant. This profile closely matches the expectations of a singular isothermal sphere profile where if $v(r)$ is approximately constant then the density $ρ ∝ r^{−2}$ to some inner "core radius" where the density is then assumed constant. Observations do not comport with such a simple profile, as reported by Navarro, Frenk, and White in a seminal 1996 paper.

The authors then remarked that a "gently changing logarithmic slope" for a density profile function could also accommodate approximately flat rotation curves over large scales. They found the famous Navarro–Frenk–White profile, which is consistent both with N-body simulations and observations given by $$\rho (r) = \frac{\rho_0}{\frac{r}{R_s}\left(1+\frac{r}{R_s}\right)^2}$$ where the central density, $ρ_{0}$, and the scale radius, $R_{s}$, are parameters that vary from halo to halo. Because the slope of the density profile diverges at the center, other alternative profiles have been proposed, for example the Einasto profile, which has exhibited better agreement with certain dark matter halo simulations.

Observations of orbit velocities in spiral galaxies suggest a mass structure according to: $$v(r) = \left(r \, \frac{d\Phi}{dr}\right)^{1/2}$$ with $Φ$ the galaxy gravitational potential.

Since observations of galaxy rotation do not match the distribution expected from application of Kepler's laws, they do not match the distribution of luminous matter. This implies that spiral galaxies contain large amounts of dark matter or, alternatively, the existence of exotic physics in action on galactic scales. The additional invisible component becomes progressively more conspicuous in each galaxy at outer radii and among galaxies in the less luminous ones.

A popular interpretation of these observations is that about 26% of the mass of the Universe is composed of dark matter, a hypothetical type of matter which does not emit or interact with electromagnetic radiation. Dark matter is believed to dominate the gravitational potential of galaxies and clusters of galaxies. Under this theory, galaxies are baryonic condensations of stars and gas (namely hydrogen and helium) that lie at the centers of much larger haloes of dark matter, affected by a gravitational instability caused by primordial density fluctuations.

Many cosmologists strive to understand the nature and the history of these ubiquitous dark haloes by investigating the properties of the galaxies they contain (i.e. their luminosities, kinematics, sizes, and morphologies). The measurement of the kinematics (their positions, velocities and accelerations) of the observable stars and gas has become a tool to investigate the nature of dark matter, as to its content and distribution relative to that of the various baryonic components of those galaxies.

Further investigations

The rotational dynamics of galaxies are well characterized by their position on the Tully–Fisher relation, which shows that for spiral galaxies the rotational velocity is uniquely related to their total luminosity. A consistent way to predict the rotational velocity of a spiral galaxy is to measure its bolometric luminosity and then read its rotation rate from its location on the Tully–Fisher diagram. Conversely, knowing the rotational velocity of a spiral galaxy gives its luminosity. Thus the magnitude of the galaxy rotation is related to the galaxy's visible mass.

While precise fitting of the bulge, disk, and halo density profiles is a rather complicated process, it is straightforward to model the observables of rotating galaxies through this relationship. So, while state-of-the-art cosmological and galaxy formation simulations of dark matter with normal baryonic matter included can be matched to galaxy observations, there is not yet any straightforward explanation as to why the observed scaling relationship exists. Additionally, detailed investigations of the rotation curves of low-surface-brightness galaxies (LSB galaxies) in the 1990s and of their position on the Tully–Fisher relation showed that LSB galaxies had to have dark matter haloes that are more extended and less dense than those of galaxies with high surface brightness, and thus surface brightness is related to the halo properties. Such dark-matter-dominated dwarf galaxies may hold the key to solving the dwarf galaxy problem of structure formation.

Very importantly, the analysis of the inner parts of low and high surface brightness galaxies showed that the shape of the rotation curves in the centre of dark-matter dominated systems indicates a profile different from the NFW spatial mass distribution profile. This so-called cuspy halo problem is a persistent problem for the standard cold dark matter theory. Simulations involving the feedback of stellar energy into the interstellar medium in order to alter the predicted dark matter distribution in the innermost regions of galaxies are frequently invoked in this context.

Alternatives to dark matter
There have been a number of attempts to solve the problem of galaxy rotation by modifying gravity without invoking dark matter. One of the most discussed is modified Newtonian dynamics (MOND), originally proposed by Mordehai Milgrom in 1983, which modifies the Newtonian force law at low accelerations to enhance the effective gravitational attraction. MOND has had a considerable amount of success in predicting the rotation curves of low-surface-brightness galaxies, matching the baryonic Tully–Fisher relation, and the velocity dispersions of the small satellite galaxies of the Local Group.

Using data from the Spitzer Photometry and Accurate Rotation Curves (SPARC) database, a group has found that the radial acceleration traced by rotation curves could be predicted just from the observed baryon distribution (that is, including stars and gas but not dark matter). The same relation provided a good fit for 2693 samples in 153 rotating galaxies, with diverse shapes, masses, sizes, and gas fractions. Brightness in the near infrared, where the more stable light from red giants dominates, was used to estimate the density contribution due to stars more consistently. The results are consistent with MOND, and place limits on alternative explanations involving dark matter alone. However, cosmological simulations within a Lambda-CDM framework that include baryonic feedback effects reproduce the same relation, without the need to invoke new dynamics (such as MOND). Thus, a contribution due to dark matter itself can be fully predictable from that of the baryons, once the feedback effects due to the dissipative collapse of baryons are taken into account. MOND is not a relativistic theory, although relativistic theories which reduce to MOND have been proposed, such as tensor–vector–scalar gravity (TeVeS), scalar–tensor–vector gravity (STVG), and the f(R) theory of Capozziello and De Laurentis.

A model of galaxy based on a general relativity metric was also proposed, showing that the rotation curves for the Milky Way, NGC 3031, NGC 3198 and NGC 7331 are consistent with the mass density distributions of the visible matter, avoiding the need for a massive halo of exotic dark matter.

According to recent analysis of the data produced by the Gaia spacecraft, it would seem possible to explain at least the Milky Way's rotation curve without requiring any dark matter if instead of a Newtonian approximation the entire set of equations of general relativity is adopted.

In March 2021, Gerson Otto Ludwig published a model based on general relativity that explains galaxy rotation curves with gravitoelectromagnetism.
