Origin 
People have been making cheese since before history was written down. It is not known when cheese was first made. It is known that cheese was eaten by the Sumerians in about 4000 BC.

Classification 
There are many different ways to classify cheeses. Some ways include:

 How long the cheese was aged 
 The texture of the cheese. These include Hard, Soft and Softer.
 How the cheese was made
 What type of milk was used to make the cheese. This is mainly what animal the milk comes from, such as cows, sheep, and goats. The diet of the animal can also affect the type of cheese made from its milk.
 How much fat is in the cheese
 What color the cheese is (common colors are yellow, and white)

There are also man-made foods that some people use instead of cheese. These are called Cheese analogues.

Different types of cheese include:

The constitution of a country (or a state) is a special type of law document that tells how its government is supposed to work. It tells how the country's leaders are to be chosen and how long they get to stay in office, how new laws are made and old laws are to be changed or removed based on law, what kind of people are allowed to vote and what other rights they are guaranteed, and how the constitution can be changed.

Limits are put on the Government in how much power they have within the Constitution (see Rule of Law ). On the other hand, countries with repressive or corrupt governments frequently do not stick to their constitutions, or have bad constitutions without giving freedom to citizens and others. This can be known as dictatorship or simply "bending the rules". A Constitution is often a way of uniting within a Federation.
The UK's constitution is not written in one single document like many other countries' are. In fact, the UK's constitution is not completely written down at all. Some of it can be found in writing, starting with the Magna Carta of 1215 and the Bill of Rights Act 1689 and including more modern Acts of Parliament. Other parts of it are considered common law and are made up of the decisions of judges over many hundreds of years in a system called legal or judicial precedence. Because of this, some people say that the United Kingdom has a de facto or "unwritten" constitution.
 
The United States in 1787 began a trend in the writing of constitutions. The United States Constitution is also the shortest that people are still using, and it has been changed (amended) many times over the years. It was made after the colonists won their independence from Britain. At first they had the Articles of Confederation but the Articles were replaced with today's Constitution.
The Indian constitution of 1950 is the longest ever written constitution in the world. It originally consisted of 395 Articles arranged under 22 Parts and 8 Schedules. As of 2021, it has 470 Articles, 12 schedules, and 25 Parts with 5 appendices and 98 amendments.

A circle, also known as a nought, is a round, two-dimensional shape. All points on the edge of the circle are at the same distance from the center.

The radius of a circle is a line from the center of the circle to a point on the side. Mathematicians use the letter  for the length of a circle's radius. The center of a circle is the point in the very middle. It is often written as .

The diameter (meaning "all the way across") of a circle is a straight line that goes from one side to the opposite and right through the center of the circle. Mathematicians use the letter  for the length of this line. The diameter of a circle is equal to twice its radius ( equals  times ):

The circumference (meaning "all the way around") of a circle is the line that goes around the center of the circle. Mathematicians use the letter  for the length of this line.
The number  (written as the Greek letter pi) is a very useful number. It is the length of the circumference divided by the length of the diameter ( equals  divided by ). As a fraction the number  is equal to about  or  (which is closer) and as a number it is about .

The area, , inside a circle is equal to the radius multiplied by itself, then multiplied by  ( equals  times  times ).

Calculating π
 can be measured by drawing a circle, then measuring its diameter () and circumference (). This is because the circumference of a circle is always equal to  times its diameter.

 can also be calculated by only using mathematical methods. Most methods used for calculating the value of  have desirable mathematical properties. However, they are hard to understand without knowing trigonometry and calculus. However, some methods are quite simple, such as this form of the Gregory-Leibniz series:
While that series is easy to write and calculate, it is not easy to see why it equals . A much easier way to approach is to draw an imaginary circle of radius  centered at the origin. Then any point  whose distance  from the origin is less than , calculated by the Pythagorean theorem, will be inside the circle:

Finding a set of points inside the circle allows the circle's area  to be estimated, for example, by using integer coordinates for a big . Since the area  of a circle is  times the radius squared,  can be approximated by using the following formula:

Capitalization (North American spelling), or capitalisation (British spelling), is a process to make one letter or more uppercase.  The first letter of a sentence is capitalised in many languages, as are the first letters of proper nouns such as names of people and places.  In German, however, all nouns are capitalized..

In the Latin alphabet, which is used in English, these are the uppercase or capital letters:

A, B, C, D, E, F, G, H, I, J, K, L, M, N, O, P, Q, R, S, T, U, V, W, X, Y, Z

These are the lowercase or small letters:

a, b, c, d, e, f, g, h, i, j, k, l, m, n, o, p, q, r, s, t, u, v, w, x, y, z

The homonym capitalize is a different word, and means "to fully fund as an investment".

Cuba is an island country in the Caribbean Sea. The country is made up of the big island of Cuba, the Isla de la Juventud island (Isle of Youth), and many smaller islands. Havana is the capital city of Cuba. It is the largest city. The second largest city is Santiago de Cuba. In Spanish, the capital is called "La Habana". Cuba is near the United States, Mexico, Haiti, Jamaica and the Bahamas. People from Cuba are called Cubans (cubanos in Spanish). The official language is Spanish. Cuba is warm all year.

In 1492, Christopher Columbus landed on the island of Cuba. He claimed it for the Kingdom of Spain. Cuba became a Spanish colony until the Spanish–American War of 1898. After the war, it was part of the United States. It gained independence in 1902.
In 1959, guerrilla fighters led by Fidel Castro and Che Guevara overthrew Cuba's dictator, Fulgencio Batista, in what became the Cuban Revolution. Castro began making relations with the Soviet Union and tried to close a lot of American businesses in Cuba; the United States did not like this. In 1961 Castro officially announced that his government was socialist. The US attempted to invade Cuba to regain control of it and overthrow its communist-led government but failed. The Communist Party of Cuba was created in 1965 and has ruled the island ever since. Today, Cuba is the only socialist state outside of Asia, in the Caribbean, and in the western hemisphere.

Culture 
Cuba is famous for many types of music, especially dance music such as the Salsa and Mambo. Because Cubans have ancestors from Spain, Africa, South America and North America, Cuban music is special and different.
Reading is very popular in Cuba. Many people especially enjoy reading books or things that come from outside the country, even though the government does not approve of this. They also love music and sports. Cuban music is very lively. This is because a lot of it comes from African and Spanish rhythms. Baseball, basketball, and athletics events are loved by many Cuban people. The Chiefs football-team took at one Football-World-Cup part. In 1938, they reached the quarter-final and lost against Sweden 0:8.

History
History

Early history 
Before Cuba was conquered by the Spaniards, three tribes lived on the island. They were the Taínos, the Ciboneys, and the Guanajatabeyes. The Taínos were the largest and most common of the three tribes. They farmed crops such as beans, corn, squash, and yams. The Taínos also slept in hammocks, which the Spaniards would introduce to the rest of the world. Then, in 1492, Christopher Columbus arrived in Cuba on his first trip to the Americas. Three years later, he claimed the islands for the Spanish. The Spanish began to rule Cuba afterwards. The Spanish brought thousands of slaves from Africa to Cuba to work for them. Most of the native Cubans died because of the new diseases brought by the Spanish and Africans. The Spanish also treated the native Cubans very cruelly and massacred many of them.
Cuban Revolution 
In 1959, Fidel Castro led a revolution against Fulgencio Batista. Castro took power in Cuba with Che Guevara from Argentina, his brother Raul, and others who fought against Batista. Castro made many changes to Cuba. He ended American ownership of Cuban businesses. This made Castro unpopular in America and the United States banned all contact with Cuba. Many Cubans went to America because of this. In 1961, the Americans helped some of these Cubans to attack Cuba and try to remove Castro, but they failed. Castro then asked the Soviet Union to help defend them from the Americans, which they did. The Soviet Union put nuclear weapons in Cuba and aimed them at the United States. American President Kennedy demanded that they be removed or a new war would begin. This was known as the Cuban Missile Crisis. The Soviet Union removed the missiles when the United States agreed to not continue attacking Cuba and to remove missiles from Turkey.
Cuba became a communist-led country like the Soviet Union after this. The Soviet Union bought most of Cuba’s sugar for expensive prices. Cuba spent this money on health, education and the army. This made Cuba’s schools and hospitals some of the best in the world. The army fought in Africa to support black Africans against the white South African army. Cuba also supported groups in South America fighting against the dictators of those countries.

However, the Cuban government began to control most of life in Cuba under the communist system. Disagreeing with the Cuban government and Fidel Castro in public was not allowed. Some Cubans did not like this and tried to leave Cuba. Most Cubans who left went to the United States. Some Cubans who did not like the government and stayed were put in jail. Many groups from around the world protested against Cuba because of this, and demanded that Fidel Castro give up power.
In 1991, the Soviet Union collapsed. This meant that Cuba, which had sold most of its products to the Soviet Union, had no money coming into the country. The Americans made the restrictions against contact with Cuba tighter. America said the restrictions on contact would continue unless Fidel Castro gave up power. Cuba became very poor in the 1990s. This became known in Cuba as “The Special Period”. Because of the disaster, Cuba changed to allow less control by the government, more discussion amongst the people, and private shops and businesses. Cuba also tried to get tourists to visit the island.

In the 2000s, tourism to Cuba began to make money for the island again. Though Fidel Castro had remained in power, he had passed all duties to his brother Raul after an illness. Fidel Castro was one of the longest-serving heads of state. In 2018, Miguel Díaz-Canel became the official President of Cuba.
In April 2015, historic talks took place with US President Obama and Cuban General Secretary Raúl Castro in improving relations between the two nations.

The trade embargo issued by President Kennedy in the 1960s has been considerably loosened under Obama's administration. US citizens can now travel directly to Cuba at certain times of the year. Before, Americans had to go via Mexico if they wanted to go to Cuba. Americans are still not allowed to purchase or smoke Cuban cigars. The cigars are smuggled over the US-Canadian border since they are legal in Canada.

For military service, men from the age of 17 to 28 years old must go into the army for two years. It is optional for women.

In July 2021, there were demonstrations against the government. See the English Wikipedia article, 2021 Cuban protests, for details.

Administrative divisions

The country is divided into 15 provinces and one special municipality (Isla de la Juventud). The provinces are divided into municipalities.
Demographics 
The population of Cuba is close to 13 million. The people of Cuba come from three different groups. The largest group is the descendants of the Spanish settlers who came to Cuba. The smallest group is the descendants of the black African slaves who were brought in to do the work and birth children (in the barracoon) as New World slaves who could be legally sold into life time bondage in the United States. The middle-sized group is a mix of African and Spanish. The government succeeded in seeing that the three different groups were treated the same. According to a DNA Caribbean Studies Institute, the racial-makeup of the population of Cuba is:
European Cubans descend from settlers that came during the very late 15th century and onward. Most white Cubans came from many different parts of Spain, but the most numerous were the Canary Islanders, Andalusians, and Catalans. There was as well some French, Italian and English peoples. Whites makeup approximately 30% of Cuba's population as of 2012, and they mostly populate the western part of Cuba, specially cities like Havana and Pinar del Rio. These brought with them their language, religions, music and others.
Africans and Mulatto Cubans descend from the arrival of African slaves that came from various parts of Africa but the most numerous were West Africans. There were also more than 500,000 Haitians that came to Cuba during the Haitian Revolution days. Most Cuban slaves tended to come from the Kongo and Yoruba tribes, there were also the Igbos, Ewes, Fons, Fulas, Mandinkas and some others. Afro-Cubans range enormously from 33.9 percent to 70 percent of the population, and they are mostly concentrated in the east parts of Cuba. These brought with them their instruments, reigion (Santeria), and customs to the Cuban culture.
Mediterranean Cubans are about 3% of the population, however; one must know that a lot of the Southern Spaniard Cuban descendants have good portion of Moor blood in their family lines; due to the close proximate Spain is to North Africa. Many Mediterranean Cubans came during the 1820s-1880s and sometimes onward. These are most concentrated in the East specially cities like Guantanamo Bay. They brought much of their foods and cuisines to Cuba and a few vocabularies.
Health and education 
Cuba is a developing country, and is often depicted as a very poor country. In some aspects, however, like education, health care and life expectancy it ranks much better than most countries in Latin America. Its infant death rate is lower than some developed countries. The average life expectancy is 78 years.

All the children are required to go to school from six to twelve years old, and nearly everybody is able to read and write at least. There is free education at every level. Because of this, Cuba has a 99.8% literacy rate.

In 2006, the World Food Programme certified Cuba to be the only country in this region without undernourished children. In the same year, the United Nations said that Cuba was the only nation in the world that met the World Wide Fund for Nature's definition of sustainable development.

Geography
Geography 

Cuba is the largest island in the West Indies. It has many resources. Only about one-fourth of the land is mountains or hills. Much of the land is gentle hills or plains which are good for farming or raising cattle. Cuba has fertile soil and a mostly warm and humid climate that makes it a great place for growing crops.
Cuba has a semi-tropical climate. That means that the cool ocean winds keep it from becoming hot, despite it being in the tropical zone. Cuba has a wet season and a dry season. The dry season is from November to April, and the wet season is from May to October. August to October is also the hurricane season in the Atlantic Ocean. Because of this, most of Cuba's port cities can be flooded along the coast.

A cube is a type of polyhedron with all right angles and whose height, width and depth are all the same. It is a type of rectangular prism, which is itself a type of hexahedron.

A cube is one of the simplest mathematical shapes in space. Something that is shaped like a cube can be called cubic.
Surface area of cube=6l^2
Lateral Surface area of cube=4l^2
Volume of cube=l^3

Relative 2-dimensional shape 
The basic difference between a cube and a square is, a cube is a 3D figure (having 3 dimensions) i.e. length, breadth and height while a square has only 2 dimensions i.e. length and breadth.
The 2-dimensional (2D) shape (like a circle, square, triangle, etc.) that a cube is made of is squares. The sides (faces) of a cube are squares. The edges are straight lines. The corners (vertices) are at right angles.  A cube has 8 corners, 12 edges and 6 faces, as in the most usual kind of dice. A tesseract carries this idea into the fourth dimension (4D) and is made of 8 cubes.
Volume 
 The volume of a cube is the length of any one of the edges (they are all the same length so it does not matter which edge is used) cubed. 
 This means you multiply the number by itself, and then by itself again. 
 If the edge is named 'd' (See Diagram), the equation would be this: Volume=d×d×d (or Volume=d3).

December (Dec.) is the twelfth and last month of the year in the Gregorian calendar, coming between November (of the current year) and January (of the following year). It has 31 days. With the name of the month coming from the Latin decem for "ten", it was the tenth month of the year before January and February were added to the Roman calendar.

December always begins on the same day of the week as September, and ends on the same day of the week as April.

December's flower is the Narcissus. Its birthstone is the turquoise.

Some of the holidays celebrated in December are Christmas, New Year's Eve, Kwanzaa, and Hanukkah.

The Month 

December is the twelfth and last month of every calendar year in the Gregorian calendar, and is one of seven months of the year to have 31 days. December 31 is followed by January 1 of the following year.
December begins on the same day of the week as September every year, as each other's first days are exactly 13 weeks (91 days) apart. December ends on the same day of the week as April every year, as each other's last days are exactly 35 weeks (245 days) apart.

In common years, December starts on the same day of the week as April and July of the previous year, and in leap years, October of the previous year. In common years, December finishes on the same day of the week as July of the previous year, and in leap years, February and October of the previous year. In leap years and years immediately after that, December both starts and finishes on the same day of the week as January of the previous year.
In years immediately before common years, December starts on the same day of the week as June of the following year, and in years immediately before leap years, March and November of the following year. In years immediately before common years, December finishes on the same day of the week as September of the following year, and in years immediately before leap years, March and June of the following year.

December is one of two months to have a solstice (the other is June, its seasonal equivalent in both hemispheres), and in this month the Tropic of Capricorn in the Southern Hemisphere is turned towards the Sun, meaning that December 21 or December 22 is the Northern Winter Solstice and the Southern Summer Solstice. This means that this date would have the least daylight of any day in the Northern Hemisphere, and the most in the Southern Hemisphere. There are 24 hours of darkness at the North Pole and 24 hours of daylight at the South Pole.
In mainly Christian countries, December is dominated by Christmas, which is celebrated on December 25 in most of those countries, though Eastern Orthodox Christians celebrate it on January 7. It marks the birth of Jesus Christ. Epiphany, January 6, is also important in relation to Christmas. Advent starts on the Sunday on, or closest to, November 30, and some countries have their own related celebration before the 25th. Sinterklaas is celebrated on December 5 in the Netherlands and Belgium, and St. Nicholas Day on December 6 is also celebrated in some countries. The Scandinavian countries, mainly Sweden, celebrate St. Lucia Day on December 13, while Iceland celebrates Thorlaksmessa on December 23. The week after Christmas is spent preparing for New Year.

Judaism's festival of light, Hanukkah, is also celebrated over eight days in this month.

Dublin () is the capital of the Republic of Ireland, and the biggest city on the island of Ireland. In 2011, there were over 1.1 million people living in the Greater Dublin Area.

Dublin was built by the Vikings upon the river Liffey. The river divides the city into two parts, North Dublin and South Dublin.

Many famous writers lived in Dublin. Oscar Wilde and George Bernard Shaw were born in Dublin. James Joyce is probably Dublin's best known and most international writer.

Dublin is home to Ireland's largest stadium for all sports, Croke Park. It can hold up to 85,000 people. Croke Park is the usual venue for all Ireland hurling and football finals. The Aviva Stadium hosts rugby and soccer.

Dance is a performing art. It is described in many ways. It is when people move to a musical rhythm, like a drum beat. They may be alone, or in a group. The dance may be an informal play, a part of a ritual, or a part of a professional performance. There are many kinds of dances, and every human society has its own dances.

As with other performing arts, some people dance to express their feelings and emotions, or to feel better. Dance can be used to tell a story. In some societies, dance goes with song as well as music. Dancing is sometimes done as sport, and has similar athletic aspects. People who want to learn to dance can go to dance schools. It may take years of practice to become an experienced and capable dancer.
To plan a dance is called choreography, done by a choreographer. Often this goes with music, and fits into a certain style. Dances may be planned in detail, or they may be whatever dancers feel like doing. However, most dancing does follow some general style or pattern. One style is the couple dance, where (usually) a man and a woman dance together. Other dances need an ensemble, a group of people together to make it work.

History 

People have always danced. Many cultures have their own dances. There are pictures, on pottery and stone, which show dances from several thousand years ago, in Egypt and Greece.
Sachs divides early dances into 'Imageless dances' and 'Image dances'. By 'imageless dances' he meant dances which have no set form, but aim at getting the dancers into a state of ecstasy. In this state the dancer(s) seem changed, in a trance, and are often thought of (by their society) as being 'possessed by spirits'. These dances are done on certain occasions: marriage, war, famine, illness or death, and so on. They are found in all early ('primitive') societies.p49; 62
The 'image dances', according to Sachs, are to do with the world outside the dancer. By imitating an animal or object, the dancer believes he can capture a power and make it useful. To dance in imitation of the animal which is going to be hunted is to become one with them. To imitate the act of sex is to achieve fertility. This is the kind of thinking behind an image dance. Sachs points out that societies of this kind do not really understand the connection between cause and effect. They really believe the image dances work. The dance type which is used in image dances is mime.p49; 77

The two styles of dance may be joined. Fertility dances may involve both ecstatic states and mime. The great dancer Nijinsky used some of these ideas in his choreography for the ballet Le Sacre du Printemps (The Rite of Spring), a ballet about the sacrifice of a girl during a primitive celebration of Spring.
In more recent times, the first dance school we know about was opened in 1661 in Paris. Only men were accepted until 1681. After 1681, women were accepted too. Ballroom dances are forms of modern dance. Ballroom dances such as the waltz are done by couples.

Until the 20th century, most ballroom dances were sequence dances. The way people moved was planned in set formation. These formations were usually lines or squares. Everyone moved at the same time, and finished at the same time. The music played for a set time, and then stopped. After the invention of the waltz, around 1800, another style of dancing developed. In the waltz, and later dances, people danced in couples, but they did so separately. They did not dance in formation, but moved round the room as they pleased (but anti-clockwise). Often, new dance styles arrive. Some dance as individuals, separately, as they please. Street dance is like that. All these types of dance have music.
At the same time, round the world there are many traditional dances. Some of them have been going for hundreds of years. We call them folkloric dances.

The coming of popular music videos and DVDs led to a kind of dancer previously seen in some stage shows. A backup dancer (or background dancer) is a performer who dances with or behind the lead performers in a live musical act or in a music video.

The dissolution of the monasteries was an event that happened from 1536 to 1540, when English King Henry VIII took away the land and money that the nuns and monks of the Roman Catholic church owned. Henry VIII then gave this land and money to people that supported him.

This was also when Henry VIII made himself the new head of the Church of England (which is a type of Christianity). Parliament made the Act of Supremacy to give him the right to do both these things. It was part of the Protestant Reformation in England.

A deadline is a time by which some task must be completed.

Very often, it means a time limit that is set in place by an authority - for example, a teacher tells students that they must turn in their homework in by a certain time. This is so the teacher is able to report fairly to his or her principal that every student had the same chance to do the work.

Deadlines may also be set by a time horizon that comes from something that is not a human authority, but part of nature.  For example, by sunset one must do those tasks requiring daylight.  However, a human must watch the sun and decide what light is strong enough to still be daylight, so time limits will still be involved even if one observes a horizon and sets a deadline oneself.

A way to remember this is that a time horizon is like the physical horizon where sunset happens and a time limit is a thing people set up to deal with this. A deadline is a thing powerful people set up to ensure less powerful people comply with their way of doing things.

Dutton Speedwords is a  made-up language written by Reginald John Garfield Dutton. The idea of Dutton Speedwords is to make frequent words short, and very frequent words very short. Dutton Speedwords can be used as a second language for international communications. Dutton Speedwords is also a shorthand writing system – this means you can use it to write quickly. 

The method was made up by Reginald John Garfield Dutton (1886-1970) in 1922. It was first published in 1935. It was called International Symbolic Script. A year later, it was called Speedwords. It was changed in 1946 and 1951.

It has two uses; to be a language and to be used for writing quickly. Dutton hoped that this would mean more people would learn it because they could use it for two reasons.

The books that Dutton wrote about Speedwords are not printed anymore. But Speedwords is now being used by more people because they find it is good for working online. For example, it makes it faster to type an email.
Another way of writing quickly is Pitman's shorthand. This uses special symbols instead of letters. Speedwords uses Roman letters. This makes it easier to learn. It also means it can be typed using a normal keyboard. Each word means only one thing. This means you do not need to use different forms of the same word.

The words used in Speedwords are the same as the words used in many other languages. The words are like short versions of the writer's own language.

In some religions and mythology, the Devil is an evil spirit, demon or supernatural being that tries to create problems for people and distance them from God. In some cultures, the Devil seen as the embodiment of evil. He is characterised by his red skin, horns and tail.

Some people also use the words "the Devil" or "Satan" for the most powerful devil.

Etymology 
The word "devil" comes from the Greek word "diabolos" which means "someone who tells lies to hurt you". ("Diabolos" is translated to the English word "slanderer.") The New Testament uses "diabolos" as a title for Satan, so "the Devil" became another name for Satan in English.

In the Old Testament, there is the Serpent and the Shaitan, who may be two different characters. "Shaitan" in Hebrew means "adversary", which is a word for an enemy or opponent. It is also a word used for the Devil in the Koran, who often appears as an animal and tries to get people to do the wrong thing.

Appearances in religions
Christianity 
According to Christianity, the Devil wanted to be a deity besides God and be independent from God. Therefore, a war in heaven started and the angels battled. After the Devil lose the battle and was thrown out of heaven, he started doing bad things on the earth. He wants people to worship him instead of God. Sometimes he tries to trick people by giving them false promises.

The other angels who were thrown out of heaven became evil spirits called demons. They obey the Devil and help him do evil things.

The Book of Revelation says that God will punish the Devil and his demons by throwing them into a Lake of Fire that burns in Hell. This will happen in the future.

Some Christians understand the Devil as the embodiment of chaos and death. They think that the Devil is the farest someone can get away from God. God, as the opposite of the Devil, stands for life and the Devil for death. The closer someone gets to the Devil the closer people come to death and will not be resurrected.
Islam 
In Islam, there is not only one devil, but there are several devils, who support Satan. The devils are invisible and tempt humans and djinns into sin. Humans and djinns, who follow the will of the devils, are called devils too.

Other cultures and religions 
Not all religions believe in the Devil. For example, some forms of Buddhism do not believe in the Devil. Judaism, has Satan, but does not believe that Satan is the Devil, but only an angel.
In Wicca, the concept of the Devil and demons is also rejected, simply because, in Wiccan tradition, the creative energy is neither positive nor negative. According to Wiccans: "We are the ones who use this energy for good or evil. Therefore, the consequence of this action is our entire responsibility, not of an evil supernatural being." The corniferous god Cernunnos of Wicca was confused with the Christian Devil, for having horns (in antiquity, given the horns were phallic, they were associated with virility (fertility)), and were soon symbols of ancient European religions. He was already worshipped by pagan religions before Christianity arrived in Europe and the British Isles. Many satanists believe in the Devil or Satan only as a metaphor, not an actual being or person. In the Bahá'í Faith, the Devil as a malevolent, supernatural entity is not believed to exist. These terms do, however, appear in the Bahá'í writings, where they are instead used as metaphors for the lower nature of man.
Arts 
Artists draw pictures of the Devil that show him as ugly and evil. But nobody knows what he may look like in fact. Usually he is a spirit that nobody can see, but he can make himself look like a real person in order to trick people. Many modern depictions of the Devil portray him as a red human-like being with horns and a pointed tail, carrying a red pitchfork or trident.

Diarrhea (DIE-uh-REE-uh), also spelled diarrhoea, happens when the body makes more watery feces than normal. Diarrhea can occur in humans as well as most other mammals.

Causes 
Diarrhea is not a disease. But it may be a symptom of a disease. The most common causes of diarrhea are:
 Viruses, like Norovirus (the most common cause of viral gastroenteritis—"stomach flu"—in humans)
 Bacteria, like E. coli or C. diff
 Some medicines, especially antibiotics
 Food poisoning
 Lactose intolerance
 Artificial sweeteners, like sorbitol and mannitol, which are in many sugar-free food products like sugarless gum
 Other problems with the intestines, like Crohn's disease and irritable bowel syndrome

Child death 
In developing nations, diarrheal diseases are the second most common cause of death in children under age 5. Every year in the world, diarrhea kills around 760,000 children under age 5.

In developing countries, diarrhea is also one of the most common causes of malnutrition in children under age 5.
When children die from diarrhea, the cause is often  dehydration (losing too much water from the body). Because diarrhea is watery, it takes away a lot of the water. It also takes away electrolytes—important salts that the body needs to survive. Dehydration is extra dangerous for small children because they have less water in their bodies to begin with. This means they cannot lose as much water as adults before they start to have serious health problems.
Causes 
In developing countries, diarrhea is usually caused by an infection in the intestines. These infections can be caused by bacteria, viruses, or parasites. These infections spread easily in some developing countries because of the following reasons:
 Unsafe drinking water. Bacteria, viruses, and parasites often get into the water, which people then have to drink. Anyone who drinks the water can then get an infection that causes diarrhea.
 Sanitation, with clean toilets, is often not available. This makes it easier for infections to spread.
 Clean water and soap for washing hands are often not available, either. If people cannot wash their hands, bacteria, viruses, or parasites can stay on their hands. These microbes can then enter the mouth or get spread to other people with handshaking.

Preventing child deaths 
Child deaths from diarrhea can be prevented in different ways.
Re-hydration 
When a child is sick with diarrhea, the best way to keep them from dying is to rehydrate them (give them the water and electrolytes (salts) they are losing by having diarrhea). If the child can go to a clinic or hospital, this can be done by giving water and salts intravenously (through a needle placed into a vein).

If the child cannot go to a clinic or hospital, oral rehydration solution can be used. ("Oral" means "given by mouth"; a "solution" is a mixture.) Oral rehydration solution is a mixture of the most important things the body loses when it is dehydrated. These things are clean water, salt, and sugar. Some oral rehydration solutions have extra electrolytes, like potassium, in them also.
Some oral rehydration solutions come in packets and just need to be mixed with clean water. Oral rehydration solution can also be made at home. If the water in the area is not safe, it can be boiled to make it safe. (Boiling the water will kill any bacteria, viruses, or parasites in the water.) Salt and sugar are then mixed into the water. Drinking this mixture, after the water cools, will re-hydrate the child, if he drinks enough. Adding a banana or orange juice can add potassium to the mixture.

Breast milk will also re-hydrate a child with diarrhea.

Preventing diarrhea 
There are some ways to prevent diarrhea, or the spread of diseases that cause diarrhea. However, some of these ways are expensive and difficult to do. These include:
 Making drinking water safe
 Making sanitation better
 Making clean water and soap available for hand washing

Dimensions are the way we see, measure and experience our world, by using up and down, right to left, back to front, hot and cold, how heavy and how long, as well as more advanced concepts from mathematics and physics. One way to define a dimension is to look at the degrees of freedom, or the way an object can move in a specific space. There are different concepts or ways where the term dimension is used, and there are also different definitions. There is no definition that can satisfy all concepts. 

In a vector space  (with vectors being "arrows" with directions), the dimension of , also written as , is equal to the cardinality (or number of vectors) of a basis of  (a set which indicates how many unique directions  actually has). It is also equal to the number of the largest group of straight line directions of that space. "Normal" objects in everyday life are specified by three dimensions, which are usually called length, width and depth. Mathematicians call this concept Euclidean space.
