Zenobia is a genus of small shrubs in the family "Ericaceae". There is only one species in this genus — "Zenobia pulverulenta" from bogs of south-east of USA. The common English name of this plant is "Honeycup". It is an evergreen plant with blue-green leaves and small white flowers in the shape of bells. The genus was named in honour of Zenobia Septimia (240 — after 274), Queen of Palmira. Honeycup is cultivated as a garden plant.
In mathematics, hyperbolic geometry is a non-Euclidean geometry, meaning that the parallel postulate that defines Euclidean geometry isn't true. On a hyperbolic plane, lines that started out parallel will become further and further apart. Replacing this rule means that hyperbolic geometry is different from ordinary flat plane geometry. For example, triangles will have angles that add up to less than 180 degrees, meaning that they are too pointy and will look like the sides are sinking into the middle. Many real objects look like hyperbolic planes. For example, some types of coral and lettuce are shaped like pieces of hyperbolic planes. Other people say that it's easier to draw a map of the Internet when your map isn't flat, because there are a lot of computers around the edges but very few in the center. Some physicists even think our universe is a little bit hyperbolic. Formal definition. The parallel postulate in Euclidean geometry says that in two dimensional space, for any given line "l" and point "P" not on "l", there is exactly one line through "P" that does not intersect "l". This line is called "parallel" to "l". In hyperbolic geometry there are at least two such lines through "P". As they do not intersect "l", the parallel postulate is false. Models have been constructed within Euclidean geometry that obey the axioms of hyperbolic geometry. These models prove that the parallel postulate is independent of the other postulates of Euclid. Because there is no hyperbolic analogue to Euclidean parallel lines, the hyperbolic use of "parallel" and related terms varies among writers. In this article, the two limiting lines are called "asymptotic" and lines that have a common perpendicular are called "ultraparallel." The simple word "parallel" may apply to both. Non-intersecting lines. An interesting property of hyperbolic geometry follows from the occurrence of more than one parallel line through a point "P": there are two classes of non-intersecting lines. Let "B" be the point on "l" such that the line "PB" is perpendicular
In geometry the parallel postulate is one of the axioms of Euclidean geometry. Sometimes it is also called Euclid's fifth postulate, because it is the fifth postulate in Euclid's Elements. The postulate says that:  "If you cut a line segment with two lines, and the two interior angles the lines form add up to less than 180°, then the two lines will eventually meet if you extend them long enough." The field of geometry which follows all of Euclid's axioms is called Euclidean geometry. Geometries which do not follow all of Euclid's axioms are called non-Euclidean geometry. History. Some mathematicians thought that Euclid's fifth postulate was much longer and more complicated than the other four postulates.  Many of them thought that it could be proven from the other simpler axioms. Those who tried to do it included Omar Khayyám, and later Giovanni Gerolamo Saccheri, John Wallis, Lambert, and Legendre. Some mathematicians announced that they had proven the proposition from the simpler propositions, but they all turned out to be mistaken. Playfair's axiom. Another more recent proposition known as "Playfair's axiom" is similar to Euclid's fifth postulate. It says that: "Given a straight line and a point not on this line, you can only draw one straight line through this point that will not meet the other straight line." In fact, mathematicians found out that this axiom is not only similar to Euclid's fifth postulate, but has exactly the same implications. Mathematically, the two propositions are called 'equivalent' propositions. Today Playfair's axiom is used more often by mathematicians than Euclid's original parallel postulate. Non-Euclidean geometry. Eventually some mathematicians tried to build new geometries without using the axiom. One kind of Non-Euclidean geometry is called elliptic geometry. In elliptic geometry the parallel postulate is replaced by an axiom that states that: "Given a straight line and a point not on this line, you cannot draw a straight line through this point that will not eventually cross the other straight line." Mathematicians found that
Robert Frederick Chelsea "Bobby" Moore (12 April 1941 – 24 February 1993) was an English former footballer. He was best known for playing for West Ham United and England national team. He was the captain of England when they won the World Cup in 1966. He played 108 games for England between 1962 and 1973. When he retired, this was a national record. Only Peter Shilton and David Beckham have since played more games for England. He is regarded as one of the greatest defenders of all time. He died of colorectal cancer in Wandsworth, London.

"For the nearby road bridge, see Forth Road Bridge." The Forth Rail Bridge is more correctly called the Forth Bridge, but the title is to distinguish it from the nearby Forth Road Bridge). It is a railway bridge across the Firth of Forth (part of the River Forth) in Scotland. The bridge is a UNESCO World Heritage Site. History. Built in 1890, it is a cantilever bridge design, with three major sections, each about long, connecting to each other. The bridge is long, and is above the water. It carries about 190-200 trains every day. More than 55,000 tons of steel were used, as well as 18,122 m³ of granite and over eight million rivets. The bridge has a speed limit of 50 mph (80 km/h) for passenger trains and 20 mph (32 km/h) for freight trains. The weight limit for any train on the bridge is 1,422 tonnes (1,442,000 kg). Approximately 4,600 workers were employed in construction of the bridge.
The New River is a north-flowing river that flows from Mexico into southern California. The New River flows north 15 miles (25 km) through Mexico and another 66 miles (100 km) through California into the Salton Sea, the largest lake in California. It is one of the most polluted rivers in the United States.
Gravitational waves are ripples in spacetime which are created whenever objects with mass move. They were predicted by Albert Einstein in 1916 on the basis of his theory of general relativity. They were first directly detected on 14 September 2015. To make gravity waves strong enough to be detected, something very massive must accelerate very fast. Sources of detectable gravitational waves include binary star systems composed of white dwarfs, neutron stars, or black holes. Gravity and relativity. In physics, gravitational waves are ripples in the curvature of spacetime that travel outward from the source. Albert Einstein predicted them in 1916 on the basis of his theory of general relativity. In theory, gravitational waves transport energy as gravitational radiation.  In general relativity, gravitational waves cannot travel faster than the speed of light. They do not exist in the Newtonian theory of gravitation, in which physical interactions propagate at infinite speed. However, the detection of gravitational waves proves the last prediction of Einstein’s general theory of relativity. In 1993, the Nobel Prize in Physics was awarded for measurements of the Hulse-Taylor binary star system that suggests gravitational waves are more than mathematical anomalies. First detection. The first detection of gravitational waves was on September 14 2015. The waves were detected by LIGO and were caused by the merging of two black holes. Collision of neutron stars. Gravitational waves have been detected from the collision and merging of two neutron stars. The first detection was on 17 August 2017 by a team in Pasadena, California. The project is run by the LIGO Laboratory at Caltech. The detector is in the huge Livingston woodland in Louisiana. The detector is two two and a half mile (~4 km) long completely straight pipelines at right angles. Inside each pipe is a laser which measures any change in length. Once the gravity wave event was detected, telescopes searched for visual images of the cause. The VISTA telescope in Chile got the image. The merging happened in a galaxy called NGC 4993. This is about 40 mega parsecs or 130 mega light years away in the direction of the Constellation Hydra. By comparison, the nearby And

The rock dove ("Columba livia", also occasionally known as rock pigeon, common pigeon or just the Pigeon) is a member of the bird family Columbidae. Rock doves are now rare in the wild, only found on remote islands and rocky cliffs in the far west and south of Europe east to central Asia. Domesticated birds which have become feral, most often called feral pigeons or simply pigeons, can however be found in cities, towns and villages all over the world, picking up dropped food in streets and parks, and begging food from people. Domesticated pigeons are also kept as poultry for food, and as homing pigeons, for the sport of pigeon racing. The wild rock dove is very distinct, with a light grey back and body with two black stripes on its wings, and a dark blue-grey head with shiny feathers on the side of the neck which reflect green and purple light. Domesticated birds are much more variable, with a wide range of colours, including white, pink, and brown not seen in wild birds. Relationship to humans. Rock doves have been domesticated for several thousand years, giving rise to the domestic pigeon ("Columba livia domestica"). They have been domesticated as long as 5,000 years ago. There are many breeds of pigeons, with many sizes and colours. Domesticated pigeons are used as homing pigeons as well as food and pets. They were in the past also used as carrier pigeons. Feral Pigeons. Many domestic birds have got lost, escaped or been released over the years and have been made feral pigeons. These show a variety of colour and size, but many have the same pattern as does the rock dove. Feral pigeons are found in cities and towns all over the world. The rareness of the wild species is somewhat due to breeding with feral birds.
Twelfth Night, Or What You Will is a play written by William Shakespeare. It is a comedy. Plot. Orsino, the Duke of lllyria, is in love with the Countess Olivia. She has not dated any men for seven years because of the death of her brother, so she turns him down. Meanwhile, Viola was shipwrecked in Illyria but she has been rescued by a captain. She has lost her twin brother, Sebastian. She dresses herself as a boy and uses the name Cesario, so she can get work as a page for Orsino. As Orsino's page, Viola is sent to Olivia with love letters. Viola finds out, to her dismay, that Olivia has fallen for her (as a boy) rather than Duke Orsino. Also, Viola has already fallen in love with the Duke. Sebastian (Viola's twin, thought to be dead) comes ashore in Illyria. He thinks Viola has drowned in the shipwreck. A man named Antonio has rescued him from the surf; at some risk to himself, because Antonio fought against the Duke at one time. Meanwhile, in Olivia's house, Sir Toby Belch (her cousin) has tricked Sir Andrew Aguecheek into supporting him, by convincing him that he could be a suitor for Olivia. So with the help of Maria, Olivia's maid, and Feste, a clown, Belch plots to make a fool of the steward. Maria writes a love letter to Malvolio that will make him think Olivia has fallen for him. Malvolio falls for the joke and dresses crazily as the letter says to. Not knowing it is a joke, the Countess is horrified and has Malvolio locked away as a madman.  Belch tries to get Sir Andrew to fight a duel with Viola's "Cesario" character as she leaves but Olivia has a crush on Cesario. Viola and Sir Andrew prepare for a duel that neither one wants. Antonio intervenes to defend Cesario, because he thinks he is his friend Sebastian, and is arrested for piracy against Orsino. Olivia has become
The quokka ("Setonix brachyurus") is a small marsupial about the size of a large cat. Like other animals in the macropod family, such as kangaroos and wallabies, the quokka eats grass and small plants, and is mainly nocturnal. It lives on some small islands off the coast of Western Australia, mainly on Rottnest Island near Perth, and Bald Island near Albany. A small number live on the main land in the protected area of Two Peoples Bay, which they share with Gilbert's Potoroo. The quokka is the only member of the genus "Setonix". https://www.animal-glossary.com/quokka.shtml Description. The quokka weighs between and . It is around long with a tail. This is short for a macropod. It has a solid build, rounded ears, and a short, broad head. It looks like a very small, fat kangaroo, but it can climb small trees and shrubs. It has rough fur which is a brown colour, fading to pale brown underneath. The quokka eats a small amount of its waste products. It is about the size of a domestic cat. Behaviour. The quokka is a social animal and lives in large groups. They eat grass, sedges, succulents and leaves. They can become very sick if fed with things like bread, given to them by visitors to Rottnest Island. Visitors are now told not to feed them. Quokkas breed at any time on the mainland, but usually in late summer on Rottnest. The female quokka has two babies (called "joeys") in a year. The quokka moves in the same way as a kangaroo, using both small and large hops. Quokkas and people. Quokkas are not scared of people, so you are able to get quite close to them, particularly on Rottnest Island. It is against the law on Rottnest Island to handle or touch the animals in any way. A$100 fine can be given by the Rottnest Island Authority for picking up a quokka. People can

Scientology teaches that Xenu (pronounced (ZEE-noo)) was the dictator of a galactic confederacy of 76 planets, who was captured and imprisoned on Earth 75 million years ago after bringing billions of his people to Earth, placing them around volcanoes and killing them by using hydrogen bombs. Scientologists believe he is still being kept there these days. Xenu is very important to the beliefs of Scientology because the story of Xenu explains the believed origin of what are known as body thetans from humans. Body thetans are believed to be the essence of Xenu's people that gather around humans and cause them spiritual harm. It is the purpose of auditing within Scientology to remove these thetans from the Scientologist. The existence of Xenu has been reported by L. Ron Hubbard's writings and by Scientology spokesman Tommy Davis in an interview ABC affiliate KESQ-TV.
Henry the Young King (28 February 1155 – near Limoges, France, 11 June 1183) was the junior king to his father Henry II of England. He was crowned king in 1170, but never actually used the power. The meaning of this is that Henry II's territory covered much of northern France as well as England and Ireland. The idea may have been to have an official deputy for legal actions when Henry was in France, and to indicate the succession to the throne. In practice, Young Henry was not interested in government. According to his tutor, William Marshal, he spent his time in France going from one knights' tournament to another. The boy was married as a child to Marguerite of France (1158–1197), daughter of the French King Louis VII. The intention was political, but it did not work. War came between Henry II and Louis. Henry joined in rebellions directed at his father. A civil war (1173/74) occurred in which Young Henry and his mother, with Scots and French support, fought against Henry II. The king won, just. Young Henry died ten years later, of dysentery. As he died before his father he never achieved power.
The Three Gorges Dam () is a dam in the Three Gorges region on the Yangtze River in Sandouping, in the country of China. Being one of the largest dams in the world, it also generates the biggest amount of hydroelectric power (22,250 megawatts), pushing the massive Itaipu Dam in Brazil from first place to second place.  The Three Gorges Dam project was completed on July 4, 2012. The dam was built for flood control, irrigation, and electricity. However, this has not come without problems. The dam covers a lot of historic sites and has caused 1.24 million people to lose their homes under the rising water. The dam forms the Three Gorges Reservoir, which extends nearly upstream to the city of Chongqing. History. The dam was proposed by Sun Yat-sen, a Chinese political leader, in 1919. The site was surveyed in 1932 and 1939, by the Chinese and Japanese respectively. The Japanese drew up a plan (the Otani plan) for the dam, only to realize later that China would remain under Chinese control. Later, in 1944, the United States helped make plans for the dam, but all work on the dam stopped in 1947, because of the Chinese Civil War. In 1949, work resumed, but the work was slow because of problems in the economy. Later in 1958, some engineers who were against the dam were put in jail. In 1980, work on the dam continued faster. The National People's Congress voted in 1992 for the dam. The dam was accepted by the government, and on December 14, 1994, construction began. In 2009, the dam began to make hydroelectricity. Some new plans, such as a set of 6 new power generators under construction, became operational in the year 2011. The reservoir filled to capacity at the end of 2008. Design, cost and purpose. The Three Gorges Dam consists of a main dam wall, and a section on the right with a set of five locks, which are devices used to raise boats
