Eddie Cantor (January 31, 1892 - October 10, 1964) was an American comedian, singer, actor, songwriter. Familiar to Broadway, radio and early television audiences, this "Apostle of Pep" was regarded almost as a family member by millions because his top-rated radio shows revealed intimate stories and amusing anecdotes about his wife Ida and five daughters. His eye-rolling song-and-dance routines eventually led to his nickname, Banjo Eyes, and in 1933, the artist Frederick J. Garner caricatured Cantor with large round and white eyes resembling the drum-like pot of a banjo. Cantor's eyes became his trademark, often exaggerated in illustrations, and leading to his appearance on Broadway in the musical Banjo Eyes (1941). He was the original singer of 1929 hit song "Makin' Whoopie".

Antoine-Joseph (known as Adolphe) Sax (November 6, 1814 – February 4, 1894) was a Belgian inventor and musician who played the flute and clarinet.  He is best known for inventing the saxophone.

Biography
Adolphe Sax was born in Dinant in Wallonia, Belgium.  Adolphe began to make his own instruments at an early age.  He entered two of his flutes and a clarinet into a competition at the age of fifteen.  He studied those two instruments at the Royal School of Singing in Brussels.

Adolphe's first important invention was an improvement of the bass clarinet design.  He patented this at the age of twenty-four. In 1841, Sax moved to Paris.  Around this time he invented the saxophone.

He got a job teaching at the Paris Conservatoire starting in 1867.
 
Sax suffered from lip cancer between 1853 and 1858 but made a full recovery. He died in 1894 in Paris.

Bucharest is the capital city of Romania. It is the largest city in the country. The city has a population of 1.9 million people. It is made up of 6 "sectors". It has a humid continental climate (Cfa in the Koeppen climate classification). It became the capital of Romania in 1862. It is the centre of Romanian media, culture and art. Bucharest is the 6th largest city in the European Union by population within city limits.

According to European standards, Bucharest is an old city. The first mention of it appears in 1459. Its eclectic architecture is a mixture of historical, transitional, Communist and modern styles. In the period between the two World Wars, thanks to the elegant urban architecture and ingenuity of the urban elite, Bucharest was named "Paris of the East", or "Little Paris" (Micul Paris).

An avalanche is a natural disaster linked to snow. When there is too much snow on a mountain, some of the snow may fall, causing damage to things in its path. This is called an avalanche. People talk about avalanches because they may be dangerous to skiers and other people doing winter sports.

Large avalanches may carry stones, boulders and trees with them. They may bury people under them. If the people are not found rapidly enough by rescue teams they will die of suffocation (not getting enough air) or of hypothermia (freezing cold).

The chance of surviving an avalanche is as follows:
 92% if found within 15 minutes
 30% if found within 35 minutes (victims die of suffocation)
 nearly zero after two hours (victims die of injuries and hypothermia)

European avalanche risk table 

In Europe, the avalanche risk is widely rated on the following scale, which was adopted in April 1993 to replace the earlier non-standard national schemes. Descriptions were last updated in May 2003 to enhance uniformity pdf .

[1] Stability:
 Generally described in more detail in the avalanche bulletin (regarding the altitude, aspect, type of terrain etc.)

[2] additional load:
 heavy: two or more skiers or boarders without spacing between them, a single hiker or climber, a grooming machine, avalanche blasting.
 light: a single skier or snowboarder smoothly linking turns and without falling, a group of skiers or snowboarders with a minimum 10 m gap between each person, a single person on snowshoes.

Gradient:
 gentle slopes: with an incline below about 30°.
 steep slopes: with an incline over 30°.
 very steep slopes: with an incline over 35°.
 extreme steep slopes: extreme in terms of the incline (over 40°), the terrain profile, proximity of the ridge, smoothness of underlying ground.

Avalanche size:

Surviving avalanches 
Surviving avalanches is very difficult, as the snow rushes at a very fast rate and can bury anyone alive in seconds. However, the snow in an avalanche acts like a liquid when descending. Thus, the best way is to actually 'swim' a backstroke. This will help as the person will be able to keep his/her face up and breathe, and also not get submerged in the snow at the same time (the force of swimming backwards is in contrast and opposes the force of the snow coming in his/her direction, rather than the snow totally taking over). 

Another way is to hold on to something immediately after an avalanche occurs. The item should be strong so it itself doesn't get drifted away by an avalanche, like a tree or large and heavy rock.

The foot is a unit for measuring length. It is one of the Imperial units and U.S. customary units. The shortest way of writing the unit "foot" is by the abbreviation "ft" (or "ft."), or by a prime symbol ( ′ ).

One foot contains 12 inches. This is equal to 30.48 centimetres. It is called a foot, because it was originally based on the length of a foot.

History 
The foot was a common unit of measurement throughout Europe. It often differed in length not only from country to country but from city to city. Because the length of a foot changed between person to person, measurements were not even consistent between two people, often requiring an average. Henry I of England was attributed to passing the law that the foot was to be as long as a person's own foot. This was one of the first times a standard unit of measurement was put into place.

In 1959, the United States, Canada, New Zealand, South Africa, Australia and the United Kingdom all signed a treaty known as the 'International Yard and Pound Agreement'. This standardised the avoirdupois weight and length of all nations. Those standards are still officially used in both the Imperial system and U.S customary units.

Usage 

Road signs with height restrictions in the United States and the United Kingdom are in feet and inches. They are less commonly seen in Canada and Ireland. In the U.S. and the UK, people usually measure a person's height in feet and inches. If a person is "five foot eleven", this means that person is 5 feet and 11 inches, or about 180 centimeters. The height is written 5′ 11″

Many people born before metrication in a number of Commonwealth nations still use feet and inches. Altitude measurements are still sometimes given in feet, even in metricated nations.

The Erfurt massacre was a mass shooting that happened at the Gutenberg Gymnasium in Erfurt, Thuringia, Germany, on 26 April 2002.  

A boy that had been expelled from the school 2 months earlier, 19-year-old Robert Steinhäuser, was the person who did all the shooting. In anger, he came into the gymnasium, and shot dead 12 teachers, a secretary, two students, and a police officer. After a teacher caught him and put him in an empty room, Steinhäuser shot himself dead. In total, 17 people were killed.

Huascarán is the highest mountain in Peru, and the fourth-highest mountain in South America. The top of it is 22,205 feet (6,768 meters) high.

The mountain is located in the Ancash Region of Peru.  Huascarán has turned into a tourist attraction for mountain climbers.

Huascarán is all that is left of an extinct volcano.  It has been getting smaller and smaller.  As recently as 1970, the Ancash Earthquake caused a big part of the mountain to crumble and fall off.  That part of the mountain was all rock and ice, and it killed almost 17,000 people in small towns around the mountain.

Armand Jean du Plessis, better known as Cardinal Richelieu (9 September 1585–4 December 1642) was a French clergyman, noble, and statesman. His full name was Armand Jean du Plessis. He was later created the Duke of Richelieu and duke of Fronsac.

In order to keep the diocese of Luçon, Armand Jean needed to become a monk. He joined the Grande Chartreuse, the main monastery of the Carthusian order. This monastery is in the Isère département, near Grenoble. As a comparison, Luçon is near La Roche-sur-Yon.

He was consecrated as a bishop in 1607. For this he obtained a dispensation of the pope; at age 21, he was too young to become a bishop.  He later entered politics and became a Secretary of State in 1616. Richelieu soon rose in both the Church and the state. He became a cardinal in 1622. He became King Louis XIII's chief minister in 1624. He remained in office until his death in 1642; then Jules Cardinal Mazarin became chief minister.

The Cardinal de Richelieu was often known by the title of the King's "Chief Minister". As a result, he is sometimes said to be the world's first Prime Minister. He sought to consolidate royal power and crush domestic factions. By restraining the power of the nobility, he transformed France into a strongly centralized state. His chief foreign policy objective was to check the power of the Austro-Spanish Habsburg dynasty; although a Roman Catholic cardinal, he did not hesitate to make alliances with Protestant rulers. With these alliances, he tried to achieve this goal. His tenure was marked by the Thirty Years' War that engulfed Europe.

As an advocate for Samuel de Champlain and of the keeping of Quebec, he founded the Compagnie des Cent-Associés and saw the Treaty of Saint-Germain-en-Laye return Quebec to French rule under de Champlain, after the settlement had been captured by the Kirkes in 1629. This in part allowed the colony to eventually develop into the heartland of French-speaking culture in North America.

Richelieu was also famous for his patronage of the arts; most notably, he founded the Académie française, the learned society responsible for matters of the French language. Richelieu is also known by the sobriquet l'Éminence rouge ("the Red Eminence"), from the red shade of a cardinal's vestments and the style "eminence" as a cardinal.

The Arabs ( ʻarab) are an ethnic group widespread in the Middle East and North Africa. Arabic is one of the Semitic languages, which is also the name of the ethnic family which they belong to.

Who is an Arab 
There are three points which decide whether someone is considered Arab or not:
 Political: whether they live in a country which is a member of the Arab League (or the Arab World); this definition covers more than 450 million people.
 Linguistic: whether their main language is Arabic; this definition covers more than 423 million people.
 Genealogical: whether they can trace their ancestry back to the people who first lived on the Arabian Peninsula.

Minorities are the Iraqi Turkmens in some Arab countries. The Iraqi Turkmen are often considered Arab, but they are an Turkic ethnic group with their own language and culture. The same goes for Berbers and Bedouins.

There are many people who can be called Arabs by these points, but who do not think of themselves as Arab.  Examples include modern Egyptians (Coptics) and the Syriacs (Aramaics/Assyrians). Although they live in countries like Syria or Egypt which is part of the Arab League and speak the official language-Arabic, they are different cultural groups. They have their own languages, culture, identity and churches, such as the Coptic Church and the Syriac Catholic and Orthodox churches. Even though many have assimilated to Arab society, they have their own heritage that spans 3,000 years.

Traditional genealogy 
In Islamic and Jewish tradition, Arabs are a Semitic people who trace their ancestry from Ishmael, a son of the ancient patriarch Abraham and Hagar. Medieval Arab genealogists separate the Arabs into two groups: the "original Arabs" of South Arabia, descending from Qahtan (identified with the biblical Joktan) and the "Arabized Arabs" (musta`ribah) of North Arabia, descending from Adnan who is descended from Ishmael.

Religion
Most Arabs today follow the religion of Islam, whose greatest prophet is Muhammad. Christianity makes up the largest religious minority - most of the Christians that do consider themselves Arabs belong to the Greek Orthodox Church with smaller numbers of Roman Catholics.

While Coptic and Maronite Catholic Christians are native Arabic-speakers, many reject the Arab pan-ethnicity, but are still considered Arab by outsider sources.

There are some small communities practicing Judaism and polytheism (the worship of many gods).  Yazidis are sometimes counted as Arabs.

A mebibyte is a unit of measure. It represents 1024 * 1024 bytes. 

A mebibyte (a contraction of mega binary byte) is a unit of information or computer storage, symbol MiB.

1 MiB = 220 bytes = 1,048,576 bytes = 1,024 kibibytes

The mebibyte is closely related to the megabyte (MB). This can either be a synonym for mebibyte, or refer to 106 bytes = 1,000,000 bytes, depending on context (see binary prefix for background). The two numbers are relatively close together, but mistaking the two has nevertheless led to problems. 

The unit MiB was defined by the International Electrotechnical Commission (IEC) in December 1998.  Use of mebibyte and related units is strongly endorsed by IEEE and CIPM and is becoming more common.

One mebibyte equals 1024 (= 210) kibibytes, and 1024 mebibytes equal one gibibyte.

Mibibyte is a common misspelling, presumably from the "i" in the abbreviation or confusion about how the surrounding prefixes (i.e. "kibi" and "gibi") were actually formed.  The "i" is actually from the end of the prefix.  Tebi- and pebi- are similarly abbreviated Ti- and Pi-, but they are not usually misspelled, as storage sizes (and corresponding terms) currently are only this large in specialized situations.

Acre is a state in the Northern Region of Brazil. It borders other two states, Amazonas and Rondônia. It also borders two countries, Bolivia and Peru. Its capital city is Rio Branco. Other important cities are: Cruzeiro do Sul, Tarauacá, Sena Madureira, and Brasiléia.

The state is mostly covered by the Amazon Rainforest. There are many rivers in Acre. Some of the rivers are the Juruá, Purus River, Acre River, Tarauacá, Muru, Embirá, and Xapuri.

The economy is based on agriculture, cattle animal husbandry, and rubber production.

Until the start of the 20th century, Acre was a territory of Bolivia. Since the 19th century, most people from Acre were Brazilian people, and they created an independent state.

In 1889, the Bolivians tried to control the area again and there were fights.

On November 17, 1903, Acre become a Brazilian territory. On June 15, 1962, it was unified and became a state.

The roller coaster (some people say the simple form coaster) is a kind of theme park ride. A roller coaster is usually a small train. It has a number of carriages that travel on a track. This track has hills that go up and valleys that go down. Sometimes it has other features that will turn the train upside-down. The track can be made from wood or steel. Some roller coasters are made for children, so they do not travel very fast. Other roller coasters are made very tall and they travel very fast. Riders are generally held in place with a bar, a belt, or something similar.

Scientifically, a roller coaster works because of gravity, a force that pulls things down to the ground. Most roller coaster trains are pulled to the top of a hill on a chain. The train will slide down the track, which has a number of hills and valleys. As it slides downhill it goes faster, and it slows down when climbing.

History 
In the United States, LaMarcus Adna Thompson patented the first roller coaster on January 20, 1865. He named his ride the "Switchback Railway," and workers pulled the carriage to the top of the track. The first modern steel roller coaster was the Matterhorn Bobsleds at Disneyland. It opened in 1959.

Types of roller coasters 
Roller coaster rails are made of wood or steel.

Steel roller coasters can be separated into many more types. On a Wing Coaster riders sit on either side of a roller coaster track and nothing is above or below the riders.

On a flying roller coaster riders lie face down so they feel like they are flying. Cars hang below the track.
On a Floorless Coaster riders sit with no floor underneath them, so their feet can swing freely just above the track. 

Some roller coasters spin riders.

Both steel and wooden roller coasters can turn riders upside down.  This is called an inversion. 

Son of Beast was the only wooden roller coaster to have an inversion.  However the loop was removed after an incident and after another incident, the ride was torn down.  In 2013, Hades 360 and Outlaw Run have inversions.  The Smiler has the world record for the most inversions.

The Zimbabwe dollar was a currency for Zimbabwe from 1980 to 2009. Zimbabwe had the highest rate of inflation in the world. The rate of inflation grew to 231,150,888.87% in July 2008.

Because of hyperinflation, or inflation that is out of control, the Reserve Bank of Zimbabwe had to print banknotes with higher values to cope with the rising cost of living. In January 2009, Zimbabwe released a banknote for one hundred trillion dollars, or $100,000,000,000,000.

The Zimbabwe dollar had to be revalued three times due to the rising cost of living: in August 2006, August 2008 and February 2009. In August 2006, the first revaluation dollar was violent and too quick, meaning that many people lost their savings because they were unable to convert it into the new currency without fear of violence and corruption.

Since 12 April 2009, Zimbabwe stopped using the Zimbabwean dollar and adopted currencies from other countries, such as the United States Dollar and the Euro.

Body modification (or body alteration) is when a person changes their body in a way that lasts forever or for a long time. There are many different kinds of body modification, like piercing, circumcision, or tattoos. Almost all cultures do some kind of body modification.

Arguments
People who do not like body modification sometimes call it "disfigurement" or "mutilation." They believe that if someone changes their body, it is wrong and they are doing something dangerous or unethical.

Why people do body modification
Body modification is done for different reasons. Religions might tell people that they should change their bodies to look a certain way. Other people with body modifications might just like the way the body modifications look, or how they feel good during sex.

Kinds of body modification

Common body modification

 Body piercing is when a hole is made through the skin, and a piece of jewelry is put into the hole. Some piercings can be stretched so they fit larger, thicker kinds of jewelry.
 Tattooing is when ink is put under the skin to make a picture. Whole body tatooing and tattooing of the lips and eyes would be thought extreme by some.
 Scarification is when part of the skin is removed to create a scar.
 Branding is when the skin is burned to create a scar.

"Extreme" body modification
 Tongue splitting is when a person's tongue is split in two like a snake's.
 Subdermal implant is when a small object is placed right underneath a person's skin.
 Transdermal implant is when a small object is placed underneath a person's skin, but part of it pokes out of the skin and is visible.
 Extra ocular implant (eye jewellery) is when a tiny chip of metal is placed in someone's eye.

Other body modification
 Amputation is when a body part is cut off

A serial killer is someone who murders several people at different times (similar killers of more than one person are mass murderers and spree killers). The victims are usually people the serial killer does not know, and the killer commits his crimes to get a certain kind of excitement or other feeling. They usually have no practical motive such as robbery or revenge.

Serial killer first became a commonly used phrase for this kind of killer in the 1970s. This was the result of the crimes of people like Ted Bundy and John Wayne Gacy. Jack the Ripper is thought by many to be one of the first serial killers that many people knew about, even though his victims were killed long before the phrase was invented.

A serial killer's crimes are nearly always alike in some way. The killer may only attack a certain type of person, for instance women of a certain age or appearance (young or old, blonde or dark-haired). He may always use the same kind of weapon to kill his victims, or may treat them in a certain manner, such as tying them up with the same kind of rope or adhesive tape. Some serial killers have had very strange habits which leave evidence of their work at each crime; for instance Albert de Salvo, the Boston Strangler, would tie the cord with which he had strangled a woman around her neck in a special bow. To law enforcement officers a serial killer's habits are known as his signature, and they are always valuable leads in detecting who he is and capturing him.

Some of the worst serial killers have been doctors. Harold Shipman, a British general practitioner, is thought to have killed up to 250 of his patients. John Bodkin Adams, also British, is thought to have killed 163 patients. Burke and Hare, the 'resurrectionists', killed to sell bodies to a doctor, Robert Knox.

The World Wide Fund for Nature (WWF) is an international environmental organization. It was founded as the World Wildlife Fund, which is still its official name in Canada and the United States. 

Most of its offices are in Switzerland. Their mascot, or logo, is the Giant Panda. It is the world's largest independent wildlife management organization. It has over 5 million supporters worldwide, working in more than 90 countries. WWF supports 15,000 conservation and environmental projects around the world. It is a charity. About 90% of its fundraising money is from donations by private individuals and businesses.

The group says its mission is "to halt and reverse the destruction of our natural environment". Much of its work focuses on the conservation of three biomes that contain most of the world's biodiversity: forests, freshwater ecosystems, and oceans and coasts. Among other issues, it is also concerned with endangered species, pollution and climate change. The organization runs more than 1,200 field projects worldwide each year.

Deforestation is when forests are destroyed by cutting trees (logging) and not replanting them.  The most common reason is to clear the land to make farms and ranches.  They also cut trees for firewood and lumber and to make room for cities.  Deforestation destroys the habitat of many animals, leading to their death.  The loss is more severe in so called primary forests, which are forests that have yet been untouched by humans.  Deforestation also releases sequestered carbon. 

Restoring trees in deforested places is called reforesting.

Causes of deforestation 
Land has other uses besides growing trees.  The biggest uses of land that was once forested are for farming and ranching.  Some land is also used for roads and buildings, especially in urban areas.  As the population grows, people need to remove more trees.  They also use the wood from the trees as lumber to make buildings and other things, or they burn the trees as firewood.

Forests have the following functions:
 regulation of the water cycle
 production of soil
 providing habitat for animals
 providing most of our oxygen
 maintain the oxygen and carbon dioxide (CO2) 
 balance in the atmosphere
 regulation of temperature
 prevention of soil erosion
 tree diseases 

Forests are often planted to protect against natural disasters.  When forests are lost, very often the soil they protected is also lost.  This loss of soil is called erosion.  

Trees are also important for carbon sequestration.  When the trees burn or rot, the carbon in them returns to the atmosphere in the form of carbon dioxide.  Since carbon dioxide is a greenhouse gas, deforestation causes global warming.  Tropical deforestation is responsible for about 20% of world greenhouse gas emissions.

In 2020, a team of scientists studied worldwide deforestation efforts and found they were not working.  They said the idea of everyone working toward the same goal had to change because different groups of people had different reasons for cutting down forests.

A capillary is a blood vessel. It does not have the muscular/elastic tissue of other blood vessels. It has a single celled wall to help substances be transported through organisms.
Capillaries are small, and smaller than any other blood vessels. They are about 5-10 μms big, which connect arteries and venules, and enable the moving of water, oxygen, carbon dioxide, as well as many other nutrients and waste chemicals  between blood and surrounding tissues.

Anatomy 
Blood moves from the heart to arteries, which branch and narrow into smaller arteries, and then branch more into capillaries. After oxygen has been moved to the tissue, capillaries join and widen to become small veins and then widen more to become veins, which return blood to the heart.

The "capillary bed" is the network of capillaries supplying an organ. The more metabolically active the cells, the more capillaries it will require to supply nutrients and carry away waste products. 

Special arteries connect between arterioles and venules and are important in bypassing the flow of blood through the capillaries. True capillaries come from mainly from metarterioles and provide movement between cells and the circulation. The width of 8 μm forces the red blood cells to partly fold into bullet-like shapes in order to bypass them in single file.

Precapillary muscles are rings of smooth muscles at the start of true capillaries that handle blood flow into true capillaries and control blood flow through a body part or area.

Physiology 

The capillary wall is a one-layer tissue so thin that gas and other items such as oxygen, water, proteins and fats can pass through them driven by pressure differences. Waste items such as carbon dioxide and urea can move back into the blood to be carried away for removal from the body. 

The capillary bed usually moves no more than 25% of the amount of blood it could contain, although this amount can be increased through auto regulation by making the smooth muscle relax in the arterioles that lead to the capillary bed as well as metarterioles making themselves smaller.

The capillaries do not have this smooth muscle in their own wall, and so any change in their width is passive.  Any signaling molecules they release (such as endothelin for constriction and nitric oxide for dilation) act on the smooth muscle cells in the walls of nearby, larger vessels, e.g. arterioles.

Capillary's ability to move items can be increased by the release of certain cytokines, such as in an the body defending itself from germs.

Viriato Clemente da Cruz, an Angolan poet and politician, was born in 1928 in Kikuvo (Porto Amboim), Angola and died in Beijing, China on 13 June 1973.

He is considered one of the most important Angolan poets of his time. He wrote poems in Portuguese and Angolan languages. He took part in the fight to free Angola from Portuguese rulers.

Political work
He was educated in Luanda, the capital of Angola, which was then ruled by Portugal. As a young man in 1957 he went to Paris, where he met Mario Pinto de Andrade, another Angolan poet and politician, who helped with his political ideas. In the 1960s they helped create the group called the Popular Movement for the Liberation of Angola (MPLA—from the Portuguese name ).

The MPLA was in not in Angola at this time, but was first in Conakry (the capital of Guinea) and then later in Leopoldville, Congo (now Kinshasa the capital of the DRC). Viriato da Cruz became secretary-general of the MPLA. After some time he and others, did not agree with some people in the group and this led to fighting in the streets of Leopoldville.

Exiled in China
Viriato da Cruz went to Beijing, China in the 1960s because of the fighting in the MPLA. At first, the Chinese government welcomed him. He was well known because he had helped create the MPLA. The Chinese wanted Viriato da Cruz to help them bring Maoist socialism to Africa.

This was a big problem for Viriato and his family. His ideas were not the same as the Maoists. He thought that stronger countries can not bring a socialist revolution to other places. He was very brave and did not change his ideas. This was against the Chinese Maoist idea of world revolution.

Viriato da Cruz wanted to leave China and return to Africa, but the Chinese government would not let him go and they were not good to him. This may be because he could have made trouble for their work in Africa.

Last years of life
The last years of the life of Viriato da Cruz were unhappy and difficult. He was weak, without much food, and he died on 13 Jun 1973. His dead body was taken away in a military vehicle and his burial was without any ceremony.

Some Angolan people think that this was shocking, because Viriato da Cruz worked hard for Angola and was one of the leaders of the liberation from Portugal.

Ska is a popular music from Jamaica that began in the 1950s. Ska music that was first played at a slower tempo then became reggae in the late 1960s.

Ska music bands include singers, electric guitars, electric bass guitar, piano, organ, saxophone, trumpet, and trombone. In ska, the electric guitar and piano normally play short chords on the off-beat. If you go "one and two and three and four", the off-beat is the "and". 

A ska singer does a style of Jamaican singing called "toasting." When a singer is "toasting", they make sounds, repeat words, invent rhymes, and shout into the microphone. The Jamaican "toasting" style of singing and talking was adapted into rap music in the 1980s.

How Ska musicians dress 
Musicians who play ska dress in hats and suits. Many ska bands wear clothes with a chessboard pattern of black and white squares. Doc Martens are a common type of shoe. This pattern symbolizes the way that ska music mixes of Black and White musicans and styles of music.There was a British genre of ska-punk influenced by The Specials, Madness and the English Beat, that began to dress in kilts.

1980s Ska Revival 
Even though ska was developed in the 1950s, it became popular again in the 1980s in Britain. In the 1980s, ska bands such as The Specials, The Selecter, The Beat, UB40 and Madness played ska music.

1990s Ska mixed with punk rock 
In the 1990s, some bands mixed ska music with Punk rock to make ska-punk. This kind of ska music is from England and the United States. Some pop-punk bands from the 1990s mixed pop-punk with ska-punk.

A switch is something that changes the flow of an electrical circuit. The most common kind of switch is something (for example a railroad switch) which can be taken off of one course and put onto another. The term "switch" usually means electrical power. In applications where more than one switch is needed, (i.e. a telephone service) mechanical switches have been replaced by electronic switches which can be controlled automatically.

The switch is called a "gate" when used in a mathematical form. In logic, arguments are represented as logic gates. The use of electronic gates to work as a system of logical gates is the basic idea behind the computer —i.e. a computer is a lot of electronic switches that work as logic gates.

Types of switch 
There are many types of switches. Some of these are: 
DIP switch
Reed switch
Rocker switch
Micro switch
Relay switch
Rotary switch
Surface mount switch
Toggle switch
Tilt switch
Time switch

Other meanings 

The word 'switch' can also mean to change between two things. For example, on a railway line, sometimes the track can split into two different tracks. If the train is travelling on one line and changes over to the other, it has just done a switch.

Francis Bacon, 1st Viscount St. Alban  KC, (22 January 1561 – 9 April 1626), was an English philosopher, statesman, and author. He has been described as one of the greatest thinkers ever whose ideas have changed the way people think.

Life
He was born in London, the son of Sir Nicholas Bacon, and the nephew of Queen Elizabeth's advisor, William Cecil. He was educated at Trinity College, Cambridge. His first job was as a lawyer. He later became a Member of Parliament and in 1586 he took a leading part in having Mary Queen of Scots executed. He became a friend of Robert Deveraux, the Earl of Essex, in 1591, and received many valuable gifts from him. After Essex led a rebellion against the Queen, Bacon was one of the people who led the investigation which led to Essex's execution in 1601.

Bacon was often in trouble for spending too much, and in 1601 he was arrested for debt. When King James became king in 1603, Bacon's position improved. He was knighted in 1603. He was one of the people who argued for the joining of England and Scotland together as one country, which happened after his lifetime, in the 1700s. Bacon married Alice Barnham in 1606, and the next year he was made the Solicitor General. He continued to be given better paying positions including Attorney General, Lord Keeper, and Lord Chancellor.

He was made Baron Verulam in 1618, and Viscount St Albans in 1621. Because he did not have children both titles ended when he died.

He used his positions to make more money for himself, and in 1621 the Parliament found that he was corrupt. He was fined £40,000 and removed from all his jobs. King James overturned the fine, but he was kept as a prisoner in the Tower of London for a while.

Studies
He became best known as a leading thinker in new ways of looking at the world. His writings started and made famous a way of thinking about science. This way of thinking is now called the Baconian method. It is based on looking at the world by making experiments. After watching the results the scientist comes up with an idea to explain what has happened. This idea or hypothesis is then further tested by more experiments. This way of thinking about science is called inductive methodology. In Bacon's time these methods were linked with magic including hermeticism and alchemy. Alchemy was the study of fire, earth, water and air. Alchemists tried to make gold from lead.
