Slide projector

A **slide projector** is used to view photographic slides by using optical and mechanical methods. It contains an electric light bulb, focusing lenses. reflector and condensing lenses and a holder that holds the slide.

A flat piece of heat absorbing glass is often placed between the condensing lens and the slide, to avoid damaging the slide. This glass absorbs infrared. Light passes through the transparent slide and lens, and the resulting image is enlarged and projected onto a screen. So the audience can view its reflection.

The image may be projected onto a translucent "rear projection" screen. That is used for continuous automatic display for close viewing. This form of projection also avoids that people who look at the show interrupt the light stream or bump into the projector.

Slide projectors were common in the 1950s and 1960s as a form of entertainment; family members and friends would gather to view slideshows.

In-home photographic slides and slide projectors have largely been replaced by low cost paper prints, digital cameras, DVD media, video display monitors and digital projectors.

As of October 2004, _Kodak_ no longer manufactures slide projectors. It is also increasingly difficult in some countries to locate photo processors who will process slide film.

Video projector

A **video projector** takes a video signal and projects the corresponding image on a screen using a lens system. All video projectors use a very bright light to project the image, and most modern ones can correct any curves, blurriness, and other inconsistencies through manual settings. Video projectors are widely used for conference room presentations, classroom training, and home theatre applications.

A video projector may also be built into a cabinet with a rear-projection screen to form a single unified display device, now popular for “home theater” applications.

Common display resolutions for a portable projector include SVGA (800×600 pixels), XGA (1024×768 pixels), and 720p (1280×720 pixels).

The cost of a device is not only determined by its resolution, but also by its light output, acoustic noise output, contrast, and other characteristics.

Wall Street crash of 1929

The **Wall Street crash of 1929** was the greatest stock market crash in the history of the United States.

It happened in the New York Stock Exchange on Tuesday October 29, 1929, now known as **Black Tuesday.** Bank failures followed, resulting in businesses closing. This caused worldwide panic, which started the Great Depression. Stock prices did not reach the same level until late 1954.

## The depression (what it created)

The crash signaled the beginning of the 10-year Great Depression that affected all Western industrialized countries. Countries imposed high tariffs and otherwise restricted imports. International trade was on the decline. Soup kitchens were the place to go for food for many people. The Depression ended in the United States with the start of American mobilization for World War II at the end of 1941. People who lost their homes lived in what were Hoovervilles, blaming President Herbert Hoover for the Depression.

The Depression ended as dramatically a decade later on September 3, 1939, when the Second World War began. The widespread poverty and suffering during the 1930s. The Great Depression spread rapidly from the US to Europe and the rest of the world as a result of the connection between the United States and European economies after WWI. The Wall Street Crash was the U.S. Stock Market crash of October 29, 1929, which triggered the Great Depression.

## Causes

Stock-exchange speculation led hundreds of thousands of Americans to invest heavily in the stock market, creating an economic bubble. Many were borrowing money to buy more stocks.

> "At the turn of the 20th century, stock market speculation was restricted to professionals, but the 1920s saw millions of 'ordinary Americans' investing in the New York Stock Exchange. By August 1929, brokers had lent small investors more than two-thirds of the face value of the stocks they were buying on margin – more than $8.5bn was out on loan".

The amount of money out on loan was more than the entire amount of currency circulating in the US at the time. When a stock price declined below the amount of borrowed money, the owner had to sell to pay the debt. This caused prices to decline more. Years later, regulations limited the use of debt in this way.
Greater London

**Greater London** is a county in Southeastern England. It covers most of London. About 7.5 million people live there.

Greater London is a conurbation and one of the counties made from merging London proper with many smaller villages and towns. Together with the City of London, they form Greater London's administrative districts. In order to avoid confusion with the City of London, "Greater London" is often used to mean the whole modern urban area centred on the City of London, and not just the City of London itself.  When most people say London, they are referring to Greater London.

The county is made of all of London except the City of London. The **London** region, the same area as London, is made up of both Greater London and the City of London.

Chemical Weapons Convention

The **Chemical Weapons Convention** (**CWC**) is an arms control agreement which prohibits chemical weapons and chemical warfare. It is forbidden to make, store or use the weapons. Every country can become a part of it and most countries (188 in 2010) are. The full name is the **Convention on the Prohibition of the Development, Production, Stockpiling and Use of Chemical Weapons and on their Destruction**.

The Organization for the Prohibition of Chemical Weapons (abbreviated OPCW) is the international organization which organizes the discussions and decisions on the convention. It also checks if member states follow the rules by inspections.
Levi Strauss

**Levi Strauss** (February 26, 1829 – September 26, 1902) was a German-born American maker of clothing.

Born as _Löb Strauss_ into a Jewish family in Buttenheim in Franconia, Bavaria, now a part of Germany.  In 1847, Strauss, his mother and two sisters moved to New York City to join his brothers Jonas and Louis Löb in their dry goods business. By 1850, he had adopted the name "Levi Strauss".

In 1853, Strauss moved to bustling San Francisco, California, where the California Gold Rush was still in high gear. He expected that the mining camps would welcome his buttons, scissors, thread and bolts of fabric; additionally, he had yards of canvas sailcloth intended for tent-making and as covers for the Conestoga wagons that dotted the landscape next to every stream and river in the area.

It was on California Street that Strauss and his brother-in-law David Stern opened a dry goods wholesale business called Levi Strauss & Co.  Strauss was often found leading a pack-horse, heavily laden with merchandise, directly into the mining camps found throughout the region. The story goes that both prospectors and miners, often complaining about the easily torn cotton "britches" and pockets that "split right out" gave Strauss the idea to make a rugged overall trouser for the miners to wear. These were fashioned from bolts of brown canvas sailcloth, with gold ore storage pockets that were nearly impossible to split. Strauss exhausted his original supply of canvas as the demand grew for his hard-wearing overalls, and so he switched to a sturdy fabric called serge, made in Nimes, France. Originally called serge de Nimes, the name was soon shortened to denim.

In 1872, Strauss received a letter from Jacob Davis, a Reno, Nevada tailor. Davis was one of Strauss's regular customers, who purchased bolts of cloth from the company to use for his own business. In this letter, Davis told Strauss about the interesting way in which he made pants for his customers: he placed metal rivets at the points of strain—pocket corners and on the base of the fly. As he did not have the money to patent his process he suggested that Strauss pay for the paperwork and that they take out the patent together.

On May 20, 1873, Strauss and Jacob Davis received United States patent #139121 for using copper rivets to strengthen the pockets of denim work pants. Levi Strauss & Co. began manufacturing the first of the famous Levi's brand of jeans in San Francisco, using fabric from the Amoskeag Manufacturing Company in Manchester, New Hampshire.

Strauss died on September 26, 1902, at the age of 73. He left his thriving manufacturing and dry goods business to his four nephews—Jacob, Louis, Abraham and Sigmund Stern—who helped rebuild the company after the 1906 San Francisco earthquake and fire. The following year, Jacob Davis sold back his share of the company.

Peter Haas and his family are the primary heirs to the Levi Strauss fortune.

Fixed Dose Procedure

The **fixed-dose procedure** (FDP) was proposed in 1984 to test a substance's acute oral toxicity using fewer animals with less suffering than the older LD<sub>50</sub> test which was developed in 1927.

FDP uses 10-20 animals to find the dose that produces toxicity signs but not death, and from there predicts the lethal dose. LD<sub>50</sub> ("lethal dose 50%") uses 60-80 animals to find a dose that kills 50% of animals in a given time. FDP sometimes needs retesting using slightly higher or lower doses.

Tentacle rape

**Tentacle rape** or **shokushu goukan** (触手強姦) is illustrated pornography involving the rape of (often quite young) women. This animation is different from other animation methods due to use of tentacles to portray the rape. This was done to get around Japanese censorship laws that made it illegal to portray uncensored male genitalia being used for sexual penetration. Since tentacles are technically not genitals, they do not need to be censored. Not all examples of **tentacle erotica** are non-consensual, though. In fact, one of the earliest and most famous tentacle erotica works, a _Shunga_ print by Hokusai called _The Dream of the Fisherman’s Wife_, shows a woman enjoying sex with two octopuses.
Neapolitan

**Neapolitan** means "from the city of Naples in Italy".  It is an adjective.
Neapolitan can mean:

- Someone who lives in Naples or comes from Naples
- Neapolitan language, the language spoken in the former territory of Kingdom of two siclies"
- Neapolitan ice cream, a mixture of chocolate, vanilla, and strawberry ice cream side-by-side in the same container
- Neapolitan chord, in music, is a special chord in music.  An example would be (from bottom note upwards): D flat-F-B if followed by C-E-(G)-C
- Neapolitan Mastiff, a big breed of dog
- Neapolitan piastra, an old currency (money) which used to be used in south Italy
- Neapolitan sauce, a kind of tomato-based sauce used in Italian cooking.

Bel canto

**Bel canto** is a way of singing in opera.  It comes from the Italian, meaning "beautiful singing".

Bel canto singing means singing beautifully, flexibly and smoothly, delivering high and low notes in a similar style so that all the notes of a singer's range sound even from top to bottom.  Bel canto singing started when opera began in the 1600s, but the term "bel canto" is normally used for operas written in the early 19th century.  The operas of Rossini, Bellini and Donizetti need bel canto singing. The term "bel canto" was not used at the time.  People only started talking about "bel canto" in the mid-to-late 19th century, when a lot of new operas by composers such as Richard Wagner appeared. These new operas had to have singers with big, dramatic voices if they were to sound good.

Bel canto-style operas came back into fashion in the 1950s, having been out of favour for the previous 50 or 60 years. Today, some of the most popular operas are bel canto ones. Famous bel canto singers of recent times include the sopranos Maria Callas, Joan Sutherland, Montserrat Caballé, Beverly Sills and the tenors Francisco Araiza, Juan Diego Florez, Alfredo Kraus, Luciano Pavarotti.

Mathilde Marchesi was a famous 19th-century bel canto teacher.

Midori Days

**Midori Days** is an anime about a girl who falls in love so badly that when she wakes up she's somehow attached to her love interest's (seiji) right hand. This anime is about how these two adjust to their strange new relationship.

High school boy Seiji Sawamura is really quite a nice guy, but he's got a bad reputation and the nickname Mad Dog, earned by copious street fighting, often in pursuit of justice. His right hook is so deadly that it's got its own nickname-The Devil's Right Hand. Other students avoid him and he can not get a girlfriend. In fact, 20 girls have turned him down. But unknown to him, he has had a secret admirer for the past three years-quiet goody-two-shoes Midori Kasugano, who is so paralyzed by her shyness that she could not possibly tell him how she feels. Then, in the tradition of Minami's Sweetheart (*DE) and The Eternity You Desire, Midori falls into a coma, while Seiji finds that instead of a right hand, he now has a living glove puppet-compare to Puppet Master Sakon. A tiny, living and speaking Midori is attached to the end of his arm and reveling in his undivided attention. The situation is awkward and embarrassing but the pair find they really do like each other, even when things are switched for an episode and Seiji becomes Midori's left hand. The result is a very silly show that still manages to convey how paralyzing shyness can be and how enforced intimacy can reveal unsuspected aspects of a person's character. Based on the manga by Kazuro Inoue in Shonen Sunday, itself a surreal cartoon version of the perennial surrogate parenting and reluctant roommates genres of live-action Japanese television

Innocence

**Innocence** is the opposite of guilt.
The adjective is **innocent** (the opposite of 'guilty').

If someone is innocent of a crime it means that they did not do it.
If someone is accused of a crime, they have to go to court. The court will decide whether they are guilty or not guilty (innocent). People must be treated as innocent unless (or until) they are found guilty.

'Innocence' and 'innocent' can also be used in a slightly different way. Children are often described as 'innocent' meaning that they think the world is all good and do not yet know about the bad things in life. People talk about living in a 'state of innocence' i.e. children or people with simple minds who have not yet learned that some people are evil. In Christian cultures this sometimes meant that children did not know about sex.
Guilt

**Guilt** can mean several things:

- Guilt (emotion), when a person feels that they have done something wrong
- Guilt (law), when a court decides that someone has broken the law
- Culpability, the extent to which a person can be held responsible for something
Symphonic poem

A **symphonic poem** or **tone poem** is a piece of orchestral music which has a story attached to it or describes something such as poem or a painting or any idea which is not music.  A symphonic poem is a kind of programme music (music for instruments which has an idea outside music).

Symphonic poems were mostly written in the 19th century at the time known as the  Romantic period.  They are normally in one movement lasting perhaps between 10 and 20 minutes.  Some of the longest ones, such as _Ein Heldenleben_ by Richard Strauss are much longer, like a symphony with four movements which run into one another.

The idea can be seen in Beethoven's overtures which tell the story of the opera or play which is about to be performed.  Composers such as Felix Mendelssohn then started to write overtures which told a story but were not attached to any opera. _Fingal's Cave_ (1832) describes the sea lapping against the rocks of a cave in the Scottish Hebrides.

Franz Liszt was the composer who made the symphonic poem an important musical form.  He wrote twelve works which he called _Symphonische Dichtung_ (_Symphonic poem_) because the music developed in the same way as in a symphony.  One example is _Mazeppa_ (1851) which describes the poem by Victor Hugo about a wild horse that carries a man tied to him until he is rescued by the Ukrainians and made into their chief.

Other composers who wrote symphonic poems include Sergei Rachmaninoff, Modest Mussorgsky, Camille Saint-Saëns, Claude Debussy, Jean Sibelius, Bedřich Smetana, Antonín Dvořák, Pyotr Tchaikovsky and César Franck.

The opening of Richard Strauss’s  tone poem _Also sprach Zarathustra_ (1895-1896) has become particularly famous in recent years through its use in the movie  _2001: A Space Odyssey_.
Melody

A **melody** in music is a group of notes of various pitches (how high or low note sounds) which are played one after another. Together they make a tune in the same way that a group of words make a sentence. Some people like to sing melodies. Melodies have rhythm (the length of the notes).

In music, 'melody' contrasts with 'harmony'. Harmony means notes which are played at the same time, like chords.  Composers often think of a melody and then add harmony to it.

Some music has more than one melody happening at the same time.  When this happens throughout the whole piece, it is called polyphonic music. Rounds and fugues are types of polyphonic music. If the other melody only happens sometimes, then the second melody is called a _countermelody_.

The adjective of melody is _melodic_. There is also the adjective _melodious_ which means: 'a sweet-sounding melody'.

Music that does not have an obvious melody may be hard to understand (unless it is focused on rhythm, such as a drum solo).

Many melodies are easy to sing, while others are difficult to sing. Still other melodies are impossible to sing. Those melodies can still be played on musical instruments.
Apostolic Palace

The **Apostolic Palace**, also called the **Papal Palace** or the **Palace of the Vatican**, is the official residence of the Pope in the Vatican City.

The palace is a complex of buildings, with the Papal Apartment, the Catholic Church's government offices, a handful of chapels, the Vatican Museum and the Vatican library. In all there are over 1,000 rooms with the most famous including the Sistine Chapel and its renowned ceiling frescoes painted by Michelangelo (restored between 1980 and 1990) and Raphael's Rooms.

The other papal residences are at the Lateran Palace and the Castel Gandolfo outside Rome.

Before 1871, the Quirinal Palace was the Pope's official residence. After the final overthrow of the Papal States in 1870, the King of Italy confiscated that palace in 1871, making it the king's official residence; after the abolition of the Italian monarchy in 1946, it became the President of the Italian Republic's residence.

Transcendental number

A real or complex number is called a **transcendental number** if it cannot be found as a result of an algebraic equation with integer coefficients.

Proving that a certain number is transcendental can be very hard. Each transcendental number is also an irrational number. The first people to see that there were transcendental numbers were Gottfried Wilhelm Leibniz and Leonhard Euler. The first to actually prove there were transcendental numbers was Joseph Liouville. He did this in 1844.

Well known transcendental numbers:
- e
- π
- e<sup>a</sup> for algebraic a <samp>≠</samp> 0

Hamlet (place)

A **hamlet** is a small settlement, smaller than a village. Usually, all settlers in a hamlet are centered around a single economic activity. A hamlet may consist of a farm, a mill, a mine or a harbor. All the people living there would be workers on that farm, mill, mine or harbour. Hamlets, especially those with a medieval church may have resulted from a medieval village, that was abandoned for some reason.

Because of the small size of the settlement, there are usually no buildings which have a central or admninistratrive function. There usually is no church, town hall or pub. Roads and streets in the hamlet do not have names, most of the time. 5-6 families may live there usually within a 2km radius area.

In Germany, Austria, Switzerland and the Alsace region of France, such hamlets often have names that end in _-wil_, _-wil(l)er_, _-wyhl_ or _-viller_.
Recording Industry Association of America

The **Recording Industry Association of America** or **RIAA** is an organization that was created and paid for by large record companies. It is based in Washington, D.C. It symbolizes the entire recording industry of the United States of America. The RIAA also participates in the collection, management and distribution of music licenses and royalties.

The association is responsible for certifying gold and platinum albums and singles in the U.S. Its goals are:
1. to protect intellectual property rights worldwide and the First Amendment rights of artists;
1. to perform research about the music industry;
1. to watch over and review laws, regulations and rules that apply to the music industry.

## Members

The members of the RIAA are mostly record companies in the U.S.

## History

The RIAA was created in 1952 to create technical standards for vinyl records so any record could play on any record player without difficulty. In today's times, the RIAA's goals is to prevent piracy of records. The RIAA says that the music industry loses nearly 4.2 billion U.S. dollars a year because of this.

Pope Boniface VIII

**Pope Boniface VIII** (; c. 1230 – October 11, 1303), born **Benedetto Caetani**, was an Italian cleric of the Roman Catholic Church and the 194th Pope  from 1294 to 1303.

## Early life

Benedetto Caetani was born in 1235 at Anagni in Italy.  Caetani studied at Todi and at Spoleto where he earned a degree in law. He came from a very noble family. His family was in government.

In 1265, Caetani traveled with Cardinal Ottobuono Fieschi to England.

## Cardinal

In 1281, Pope Martin IV raised Caetani to the rank of cardinal. In 1291, Pope Nicholas IV made him Cardinal of SS. Silvestro e Martino ai Monti.

## Pope

Cardinal Caetani was elected in 1294; and he chose to be called Boniface VIII.

Pope Boniface confirmed the decree of Pope Celestine V that any pope can freely resign.

Boniface was involved in Italian and European political disputes.

Boniface VIII made a rule that if a ruler (king) fined people taxes without the church or popes' permission that the ruler would be excluded from the church. He would make rash decisions without consideration. He was known to be harsh, mean, cruel, and did not listen to other people's recommendations. For example, He declared a very rash papal law that all people, not just Christians, must follow him if they want to go to heaven. He believed as the Pope, all rulers should bow down to him and respect him.

## After his death

Dante mentions Boniface in _The Inferno._  He identifies the pope as "the Prince of the new Pharisees."

Signal (electrical engineering)

In the fields of communications, signal processing, and in electrical engineering more generally, a **signal** is any time-varying quantity.

The concept is broad, and hard to define precisely.  Definitions specific to subfields are common. For example, in information theory, a _signal_ is a codified message, i.e., the sequence of states in a communications channel that encodes a message. In a _communications system_, a _transmitter_ encodes a _message_ into a signal, which is carried to a _receiver_ by the communications _channel_.  For example, the words "Mary had a little lamb" might be the message spoken into a telephone. The telephone transmitter converts the sounds into an electrical voltage signal. The signal is transmitted to the receiving telephone by wires; and at the receiver it is reconverted into sounds.

## Examples of signals

- _Motion_.  The motion of a particle through some space can be considered to be a signal, or can be represented by a signal.  The domain of a motion signal is one-dimensional (time), and the range is generally three-dimensional.  Position is thus a 3-vector signal; position and orientation is a 6-vector signal.

- _Sound_.  Since a sound is a vibration of a medium (such as air), a sound signal associates a pressure value to every value of time and three space coordinates.  A microphone converts sound pressure at some place to just a function of time, using a voltage signal as an analog of the sound signal.

- _Compact discs_ (CDs).  CDs contain discrete bits representing a sound signal, recorded at 44,100 samples per second.  Each sample contains data for a left and right channel, which may be considered to be a 2-vector (since CDs are recorded in stereo).

- Noise typically unwanted but not always.

Air New Zealand

**Air New Zealand**  is a big passenger airline from Auckland, New Zealand. It flies mainly in Australasia and South Pacific, but it also has services to Europe, North America and Asia. It is a Star Alliance member. It joined the alliance in 1999. Its main base or hub is Auckland International Airport.

## History

In 1940, TEAL was founded. Its first flights were from Auckland to Sydney and Wellington. Later, flights to Fiji, Samoa, Tahiti and the Cook Islands were added. The Australian government bought 50% of TEAL in 1953. The remaining 50% was owned by the Government of New Zealand. In 1961, the airline became completely owned by the Government of New Zealand. _TEAL_ was officially renamed _Air New Zealand_ on April 1, 1965. The airline bought Douglas DC-8 airplanes in July 1965. These were used for longer routes to Honolulu and Los Angeles. A larger Boeing 747 was bought in 1981. Air New Zealand bought Ansett Australia in 2000. Ansett later went out of business.

Economist

An **economist** is someone who studies or works in the field of economics. Economics is the study of how people make choices to satisfy their wants.

According to Frédéric Bastiat:
- "There is only one difference between a bad economist and a good one: the bad economist confines himself to the visible effect; the good economist takes into account both the effect that can be seen and those effects that must be foreseen."

Artillery

**Artillery** is a word for the big guns used in an army, for example cannons and howitzers. Such guns are used to shoot targets far away. Artillery is often used to stop enemy troops using an area, to bombard trenches and buildings with enemies in it and to support friendly units. There are many different weapons that are called artillery. They may shoot shells or missiles. Newer systems can even drop mines over a big area, making the area uncrossable. Anti-aircraft warfare includes the use of artillery to fight planes and other aircraft.

Those who fire the artillery piece are called "gunners". In most cases someone else, called a "spotter" must see the enemy, because artillery often shoots farther than the gunners can see. The artillery crews do not have to see the enemy to damage them.

Amnesty International

**Amnesty International** (also called **AI** or **Amnesty**) is an international organization founded in London in 1961. They promote human rights in accordance with Universal Declaration of Human Rights and international human rights law.  This organization was the recipient of the Nobel Peace Prize in 1977 for its defense of human dignity against torture. It is one of the most widely-known human rights groups in the world.  The six key areas that Amnesty International focuses on are refugee rights, the rights of women, children, and of minorities, ending torture, stopping the death penalty, the rights of people imprisoned because of what they believe, and protection of human dignity.

## What they believe in

Amnesty International is based on these central ideas:
- _Every person has human rights. Human rights cannot be taken away from a person._ They are natural laws that are the right of all human beings from their birth on.
- _Human rights cannot be divided._ When one right is taken away, this is also bad for other rights. When one right is protected, other rights are in a better position as well.
- _Human rights will not be protected by governments alone._ Governments have said they will protect human rights, and then not acted upon it. Human rights organizations have to influence the governments.
- _To protect human rights, people must help other people._ Danger for human rights starts at the level of single persons. To help one person means to stop the danger from growing. One person alone can do this.
- _To defend human rights, an organization must be independent and impartial._ It should not be for or against any one ideology. An ideology is a certain point of view. It can be political, economic, or religious. Also, the organization should not say one country is the "worst". It should focus on the individual and all individuals.
