Anton Rubinstein

.]]

**Anton Rubinstein** (born Vikhvatinets 28 November 1829; died Petershof 20 November 1894) was a Russian pianist and composer.  Rubinstein and Franz Liszt were thought to be the greatest pianists of the 19th century.  He was very important as a teacher and influenced many Russian musicians.  He composed lots of music, although hardly any of it is heard nowadays.  As a composer he is best remembered today by a little piece of piano music called “Melody in F”.

## History 
### First concert 
Rubinstein gave his first piano concert when he was ten.  Between 1840 and 1843 his piano teacher took him on long concert tours of Europe.  He met Chopin and Liszt and was received in London by Queen Victoria.   Between 1844 and 1846 the family lived in Berlin.  His friends there included Mendelssohn and Meyerbeer.  

### Lessons 
In 1846 his father died and Anton went to Vienna where he gave piano lessons to try to earn some money.  When he returned to Russia in 1848 the tsar’s sister-in-law let him live in her palace.  He played for lots of parties.  Often the tsar came.

### Tours 
In 1854 he toured Europe again.  Then he returned to Russia.  He wanted to improve music education in Russia so he started the Russian Musical Society and then he started the St Petersburg Conservatory.  During his long career he spent many years as director of the Conservatory as well as conducting concerts.

## Compositions 
He wrote a lot of music, but although his compositions often started off with good ideas they often become rather boring.  His opera *Tom the fool* was not a success.  He was annoyed and wrote an article in a music magazine saying that it was not possible to write operas using Russian stories.  He criticized several composers who were writing music which used Russian folktunes.  This included the composer Mily Balakirev and his friends who were called The Mighty Handful.  He said that they had not learned how to compose properly.

Rubinstein very much wanted to be famous as a composer as well as a teacher, but this made him very narrow-minded.  However, it was as a pianist and conductor that he was important.  He helped to improve the standard of music making in Russia by teaching and performing, and by starting the conservatory in St Petersburg.
2000 United States Census

The **Twenty-Second United States Census**, known as **Census 2000** was a count of the population of the United States. It was done by the Census Bureau. It found that the population of the United States on April 1, 2000 was 281,421,906. This was an increase of 13.2% over the 248,709,873 people counted during the 1990 Census. This was the twenty-second federal census. It was the largest single administrative effort in the history of the United States that was not done during wartime.

About 16 percent of households received a "long form" of the 2000 census. It had over 100 questions.

Circumference

In geometry, circumference is the distance around a closed curve; for example, a circle. It is a special kind of perimeter. The length of the circumference of a circle is often written as C, with:
:C= \pi d
where *d* is the diameter of the circle.

Bush (mechanical)

A **bush** or bushings is a mechanical fixing between two, possibly moving, parts, or a strengthened fixing point where one mechanical assembly is attached to another.

Bushings are indeed indispensable elements that find extensive application across a multitude of industries. Their role in agriculture, construction, mining, and manufacturing equipment is particularly noteworthy.

In a car or other vehicle's suspension, bushes are used to connect the various moving arms and pivot points to the chassis and other parts of the suspension. In machines, bushes provide mechanical strength to the rotor.

Lumber

**Lumber** (or **timber**) is wood that has been cut for use in building.

## Dimensional lumber
Dimensional lumber is a term used in North America for lumber that is finished/planed and cut to standardized width and depth specified in inches.

### Softwoods
Examples of common sizes are **2×4** (also **two-by-four** and other variants), **2×6**, and **4×4**.  The length of a board is usually specified separately from the width and depth. It is thus possible to find 2×4s that are four, eight, or twelve feet in length. In the United States the standard lengths of lumber are 6, 8, 10, 12, 14, 16, 18, 20, 22, and 24 feet.

### Non-North American sizes
Outside North America sizes of timber vary slightly. Sizes are, in some cases, based on the imperial measurement and referred to as such; in other cases the sizes are too far removed from the imperial size to be referred to by imperial measurement. Lengths can be sold at every 300&nbsp;mm (a metric approximation of 1'). Common sizes are similar to the North American equivalent; 2.4, 2.7, 3.0, 3.6, 4.2, 4.8, 5.4, 6.0.  But also in running lengths, where each plank in a given packet is different, from  2500mm to 5500mm, though shorter and longer may be present.

### Hardwoods
In North America sizes for dimensional lumber made from hardwoods varies from the sizes for softwoods. Boards are usually supplied in random widths and lengths of a specified thickness, and sold by the board-foot (144 cubic inches).

### Engineered Lumber
Engineered lumber is lumber created by a manufacturer and designed for a certain structural purpose.

Suspension (vehicle)

]]
**Suspension** is the term given to the system of springs, shock absorbers and linkages.  The suspension acts as an intermediate between the car and the road and solves several problems:  

* Transfer to the frame or body of forces and moments arising from the interaction of wheels with the road surface;  
* Link wheels with body or frame;
* Provides the necessary for the normal movement of the position of the wheels relative to the frame or body and the road;
* Ensures acceptable running smoothness, compensates for uneven pavement.

So a car suspension is not just a set of components for connecting wheels and body or frame, but a complex system that makes normal and comfortable movement on car driving.

## Springs 
Springs are elastic elements of a car suspension that work in conjunction with shock absorbers. The main functions of the springs are:
*maintaining vehicle clearance under increased loads;
*ensuring reliable tire contact with the road surface;
*supporting and even distribution of vehicle weight;
*exclude transmission of vibrations and other effects on the car body.

## Shock absorbers 
Shock absorbers, as a damping element of a modern suspension, convert vibrational energy into heat. The amount of energy absorbed depends on the mass of the car, the stiffness of the spring and the vibration frequency.
The principle of operation of dampers is based on the displacement of fluid by a piston through special holes. In various modes, fluid is displaced through openings of different diameters. Due to this, the oscillations are absorbed both during compression and during rebound. As a result, these car suspension parts provide:
*vehicle traffic safety;
*control of the movement of the spring and suspension;
*efficient car control;
*axial braking force balance;
*prevention of early tire wear;
*monitoring of tire contact with the road surface;
*control of swinging and oscillations about the vertical axis;
*decrease in wearing of knots and units of the car.

## Linkages 
Using these elements, the suspension parts are fastened together, and also the suspension is attached to the body or frame of the car. The fasteners can be either a regular bolted connection (like other types of rigid joints), or a connection using special elastic elements - rubber-metal hinges (or silent-blocks).

Suzuki method

The **Suzuki method**, (or **Talent Education**, or the **Mother Tongue method**, or the **Suzuki movement**) is a way of teaching. It teaches people to be morally better through a caring environment. It normally uses a musical instrument such as the violin or piano to do this. It can also use other musical instruments like the flute, recorder, piano, guitar, cello, viola, bass, organ, harp and voice. The Suzuki method uses the same environment that people have when they learn their mother-tongue. This means that each student sees and hears music and good moral character all of the time. Other people tell them that they will do well. The students learn one thing at a time. They learn new things when they are ready. The term "Suzuki method" is also used to mean only the Suzuki sheet music books and songs.

It was created in Japan in the mid-20th century by Dr. Shin'ichi Suzuki. He was a violinist who wanted to bring some beauty to the lives of children in his country after World War II. Dr. Suzuki saw that all children learn their own language very quickly. Even dialects which adults thought were hard to learn are spoken with ease by 5 or 6-year-old children. He thought that if a person can speak their mother tongue, then they can learn to play a musical instrument. He came up with the idea that any pre-school age child could begin to play the violin.

Just as a child learns to speak before reading, Suzuki students learn by ear and generally only learn to read sheet music at a much later age.

Suzuki students will always play with a "beautiful tone and a beautiful heart".

El Puerto de Santa María

market in El Puerto de Santa Maria]]

**El Puerto de Santa María** (commonly called **El Puerto**) is a city on the banks of the Guadalete River in the province of Cádiz, Spain. As of the 2005 census, the city has 82,306 people. 50,000 of these people live in the urban center. The others live in the area around the urban center.

The city of El Puerto de Santa Maria is  northeast of Cadiz across the Bay of Cadiz. It is  best known for its ferry, El Vaporcito, which has been used for 76 years. It takes passengers to and from Cadiz to El Puerto.

## History 
In the Odyssey of Homer, legend says that, after the Trojan War, a Greek official named Menestheus escaped with his troops through the Straits of Gibraltar. They got to the Guadalete River and created a port. They called the port ''Menestheus's port*.

In 711, Arab (Moors) from the North of Africa invaded southern Spain. They changed the name to *Alcante* or *Alcanatif*. The name means Port of Salt. They chose that name because of the old salt industry of Phoenicians and Romans.

In 1260, Alfonso X of Castile took the city from the Moors. He renamed it *Santa María del Puerto''. 

Columbus began his second voyage to the New World from El Puerto. His pilot, Juan de la Cosa, created the first map of the world to include the coast of the New World in El Puerto in 1500. In the nineteenth century, the city became the General Headquarters for the French Army during the Spanish War of Independence under the reign of Joseph Bonaparte (1808–1813). The city is has much history, museums and monuments. It is also near the very historical cities of Seville and Cádiz.

## Tourism 
El Puerto has a famous bull ring. It dates back to 1880. The bull ring has space for 15,000 to watch. Bull fighting is still enjoyed during the Feria season, which is during the month of August, and during the Feria de la Primavera, which is in early May. This Feria is dedicated to sherry. 180,0000 half bottles of sherry get drunk in 4 days. There are several bodegas in the town centre. All of these can be visited by the public. The most famous bodega is the Osborne and Terry Bodegas. They export sherry and brandy worldwide . In the cellars in El Puerto, sherry is made using the traditional method called “solera”. This method makes the pale dry sherries to the sweet Muscatel sherry, Amontillados and the older Olorosos.

## Local food 
El Puerto is a very good place to taste local tapas and seafood, for which it is famous. Food is an important reason why many tourists go to El Puerto de Santa Maria. The Bay of Cadiz is famous for its fresh fish. The fish and plenty of fresh fruit and vegetables lead to very good restaurant menus. There are many different types of places to eat all in walking distance in the town centre.

Potter's wheel

A '''potter's wheel**, also known as the **potter's lathe''', is a machine used in the shaping of round ceramic wares. 

However, the name potter's lathe is also used for the machine used for another shaping process, turning, which is similar to that used for the shaping of metal and wood articles. The wheel may also be used during the process of trimming excess body from dried wares and for applying incised decoration or rings of colour.
 
## History 
Many early ceramics were hand-built using a simple coiling technique in which clay body was rolled into long threads that were then pinched and beaten together to form the body of a vessel. In the coiling method of construction, all of the energy required to form the main part of a piece is supplied directly by the hands of the potter. This changed with the introduction of the fast-wheel, early forms of which used energy stored in the rotating mass of the heavy stone wheel itself. 

## The potter's wheel in myth and legend 
In Ancient Egyptian mythology, the god Chnum was said to have formed the first humans on a potter's wheel.

## The potter's wheel in literature 
The way in which clay is shaped on a potter's wheel seems, even today, to have a magical quality to it; the clay body has the appearance of being a living thing that is being created or shaped by the potter. The potter and clay have long served as a metaphor for creation, and for the relationship of God to humankind:

:But now, O LORD, thou art our father; we are the clay, and thou our potter; and we all are the work of thy hand.
::–Isaiah 64:8

The "Rubaiyat of Omar Khayyam" make sustained use of this metaphor. In FitzGerald's translation, a number of quatrains are collected into a *Book of Pots*, in which the pots engage in theological speculation:

 living historical museum.]]

&nbsp;&nbsp;And, strange to tell, among that Earthen Lot
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Some could articulate, while others not:
&nbsp;&nbsp;And suddenly one more impatient cried–
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;“Who is the Potter, pray, and who the Pot?”
 
&nbsp;&nbsp;Another said–“Why, ne'er a peevish Boy,
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; “Would break the Bowl from which he drank in Joy;
&nbsp;&nbsp;“Shall He that made the vessel in pure Love
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;“And Fancy, in an after Rage destroy?”
    
&nbsp;&nbsp;None answer'd this; but after Silence spake
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A Vessel of a more ungainly Make:
&nbsp;&nbsp;“They sneer at me for leaning all awry;
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;“What! did the Hand then of the Potter shake?”

Flywheel

]]

A **flywheel** is a heavy  or wheel that is attached to a rotating . Flywheels are used for storage of kinetic energy. The momentum of the flywheel causes it to not change its rotational speed easily. Because of this, flywheels help to keep the shaft rotating at the same speed. This helps when the torque applied to the shaft changes often. Uneven torque can change the speed of rotation. Because the flywheel resists changes in speed, it decreases the effects of uneven torque. Engines which use pistons to provide power usually have uneven torque and use flywheels to fix this problem.

It takes energy to get a wheel (any wheel) to rotate. If there is little friction (good bearings) then it will keep rotating a long time. When energy is needed, it can be taken from the wheel again. So it is a simple mechanical means of storing energy. The amount of energy stored is a function of the weight and the speed of rotation - making a heavier wheel rotate faster takes more energy. Another factor is the radius (size) because the farther from the axis a part of the wheel is, the more energy it takes to make it rotate. These three factors can be represented by M (mass), \omega (angular velocity), and R (radius). Combining the two equations below gives \omega2MR2/4. A fly-wheel is not just any wheel, but specifically designed to store energy. So it should be heavy and/or rotate fast. For example, some buses have a fly-wheel that is used for stopping and starting. When the bus stops (e.g. for a traffic light), the fly-wheel is connected to the wheels, so the rotational energy is transferred to it, so the bus will slow down while the fly-wheel speeds up. Then, when the bus has to start driving again, it is connected again and the energy is transferred back. Of course, you wouldn't want to lug a heavy wheel around on a bus, so it is made of a lighter material that can withstand extremely fast rotation. 

## Mathematics of flywheels 
The kinetic energy of a rotating flywheel is

:E = \frac{1}{2} I \omega^2

Where the moment of inertia of center mass is equal to

:I = \frac {1}{2} MR^2

where I is the moment of inertia of the mass about the center of rotation and \omega (omega) is the angular velocity in radian units.

## History 
The flywheel has been used since ancient times, the most common traditional example being the potter's wheel. In the Industrial Revolution, James Watt contributed to the development of the flywheel in the steam engine, and his contemporary James Pickard used a flywheel.

## Other meanings 
In the world of venture capital, the term "flywheel" is used to represent the recurrent, margin-generating heart of a business.
Nikolai Rubinstein

**Nikolai Grigoryevich Rubinstein** (born Moscow, 2 June 1835; died Paris, 23 March 1881) was a Russian pianist and composer. He was the younger brother of Anton Rubinstein and a close friend of Pyotr Ilyich Tchaikovsky.

The Rubinstein family were middle-class Jewish people. Like his brother Anton, Nikolai soon showed great talent as a pianist. The family spent some time in Europe including three years in Berlin where they made friends with Mendelssohn and Meyerbeer.

Anton founded (started) the famous Conservatoire in St Petersburg where students could study music. Nikolai co-founded the Conservatoire in Moscow with Prince Nikolai Petrovitch Troubetzkoy. Both brothers were directors of the Conservatoires they had founded.

During his lifetime Nikolai Rubinstein was thought of as one of the greatest pianists of his time. As pianists the two brothers were very different. Anton was very fiery like Franz Liszt. Nikolai was quieter and more thoughtful, preferring lyrical Romantic music.

Anton liked to compose in the same way as composers from Western Europe. He was critical of Russian composers like Mily Balakirev and others from the group called The Mighty Handful who tried to make their music very Russian. Nikolai was much more broad-minded. He supported Balakirev and his group. He was a great friend of Tchaikovsky and encouraged him much more than his brother Anton had done. Nevertheless, he still criticised Tchaikovsky’s First Piano Concerto. He said he would not play it until Tchaikovsky had changed it. Tchaikovsky refused to change it. Years later Nikolai decided he liked it after all.

Although Nikolai wanted to be a successful composer he was aware that he was not a great one. When asked why he did not compose more he once replied that his brother “composed enough music for three”.

Nikolai died in Paris while on his way to Nice where he had wanted to improve his health. He always liked his food and on his deathbed he ate twelve oysters. Tchaikovsky wrote his *Piano Trio in A minor* in Rubinstein's memory.

Among his most popular works are his *Tarantella* in G minor and the *Fantasia on a Theme by Schumann*, both for piano solo.
Okinawan language

The **Okinawan language** (沖縄口, *Uchināguchi*) is a Ryukyuan language that is spoken in the Okinawa Islands of Japan.

Most linguists say that it branched off from Proto-Japonic, which is the ancestor of Japanese and the Ryukyuan languages. The Japanese government says Okinawan is a dialect of Japanese because of politics.

## History 
When a group of people called the Yayoi came into the Ryukyu Islands, they brought over a language called Proto-Japonic. This language over time turned into the modern Ryukyuan languages. Proto-Japonic was also spoken in mainland Japan, which turned into Japanese, meaning Japanese and the Ryukyuan languages are related/have the same origin.

Okinawan and other Ryukyuan languages were discriminated by Japan during the Meiji period, making the number of speakers go down. Before that, Okinawan was the official language of the Ryukyu Kingdom.

## Classification 
Okinawan belongs to the Ryukyuan languages. It is in the northern group with both Kunigami and Amami. Sometimes, Kunigami is listed as a dialect of Okinawan but that view is rare.

## Speakers 
Most older Okinawans speak Okinawan while younger Okinawans speak Japanese. This is why UNESCO lists Okinawan and the other Ryukyuan languages as “endangered”, meaning it’s possible for the language to die out in the future.

## Sound Changes (Japanese vs. Okinawan) 
There are many sound changes between Japanese (Standard) and Okinawan (Shuri-Naha variety):

Japanese “o” - Okinawan “u” (**O**kinawa = **U**chinaa)

Japanese “k” - Okinawan “ch” (O**k**inawa = U**ch**inaa)

Japanese “mi” - Okinawan “nn” (**mi**nato = **nn**atu)

Similar sound changes are in other Ryukyuan languages. Kunigami also uses “u” instead of Japanese “o”.

Imbolc

**Imbolc** is a festival belonging to Brigid, the Celtic goddess who, in later times, became famous as a Christian saint. Her festival on February 1 or 2 was known as "Imbolc" or "Oimelc". "Imbolc" or "Imbolg" means 'in the belly' - bol meaning belly in Welsh and bolg meaning belly in Irish Gaelic - refers to the pregnant ewes. "Oimelc" Gaelic refers to the lactation of the ewes. Lactation is the flow of milk that happens when the baby lambs are born in the spring, and Gaelic languages are those spoken in countries like Ireland and Scotland.

Imbolc was, and still is, a time to celebrate that winter would soon be over. Sometimes in Ireland, the first flowers are coming up at the time of this festival, even when there is still snow on the ground.

Later, the Roman Catholic Church replaced this festival with Candlemas Day on February 2, a day that now belongs to the Virgin Mary. On this day, people may have ceremonies or processions  by candlelight - walking together in the dark, with the only light coming from candles they carry. The may also sing songs to Brigid, or say poems or prayers to her.

In both Pagan and Christian celebrations, Brigid is celebrated as a powerful female figure, who brings light, inspiration, and healing to the world.
Baseball (ball)

A **baseball** is a ball used in the sport of the same name, baseball. It is between 9 inches (22.9 cm) and 9¼ inches (23.5 cm) in circumference (around). The ball weighs 8 ounces. Different size balls may be used in children's leagues. 

The balls can be made in many different, but similar ways. The center of most balls is cork, rubber, or a mixture of the two. It is sometimes layered. Yarn and twine and sometimes wool are wrapped around the center core. A leather cover is put on, in two pieces, and stitched together using 108 stitches of waxed red cotton thread. Official Major League balls sold by Rawlings are made to the exact MLB specifications (5 ounces, 108 stitches).

Betrayal

**Betrayal** is a person breaking the trust and the  of others. 

An article made by Rodger L. Jackson statesthat "there is not much definition for this word". In psychology, betrayal is said to be the breaking of social (friendship)-related things. However, for some people, such as the philosophers Judith Shklar and Peter Johnson, a person can understand the word better by literature (writings).

## Betrayal trauma
Betrayal trauma happens when someone that a person trusts betrays their trust, and that messes up their memory because of anger. An example of betrayal trauma is childhood physical or childhood problems. Betrayal trauma is similar to post traumatic stress disorder. The difference is that post-traumatic stress disorder (PTSD) is made by fear. Betrayal trauma makes a person fight and can be caused by serious crimes such as discrimination or bullying.
Band (anthropology)

In anthropology, **bands** are the tiniest societies, consisting typically of 5-80 people, most or all of them close relatives by birth or by marriage. In effect, a band is an extended family or several related extended families. Today, autonomous bands are almost confined to the most remote parts of New Guinea and Amazonia, but there were many others that have only recently fallen under state control or been assimilated or exterminated. They include many or most African Pygmies, southern African San hunter-gatherers (so-called Bushmen), Aboriginal Australians, Eskimos (Inuit), and Native Americans of some resource-poor areas of the Americas such as Tierra del Fuego and the northern boreal forests; all these modern bands are or were nomadic hunter-gatherers rather than settled food producers.  Until at least 40,000 years ago, probably all humans lived in bands, and most still did as recently as 11,000 years ago. 

Bands have no permanent single base of residence, instead land is used jointly by the whole group, as opposed to being partitioned among subgroups or individuals. There is no regular economic specialization, except by age and sex: all able-bodied individuals forage for food. There are no formal institutions, such as laws, police, and treaties, to resolve conflicts within and between bands. Organization is often described as "egalitarian" in the sense that there is no formalized social stratification into upper and lower classes, no formalized or hereditary leadership, and no formalized monopolies of information and decision making. However, this definition of egalitarian should not be taken to mean that there is equality in prestige and the decision-making process among band members. Instead "leadership" should be thought of as informal and acquired through qualities such as personality, strength, intelligence, and fighting skills.

Our closest biological relatives, the gorillas and chimpanzees and bonobos of Africa, also live in bands. All humans presumably did so too, until improved technology for extracting food allowed some hunter-gatherers to settle in permanent dwellings in some resource-rich areas. The band is the political, economic, and social organization that we inherited from our millions of years of evolutionary history. Our developments beyond it took place within the last few tens of thousands of years.

* The act of destroying something.
*Slighting, the act of damaging an important building

Crane (machine)

A **crane** is a lifting machine that has hoists, wire ropes and sheaves on it.  It can be used both to raise and lower things or to move them left and right. Cranes are often used in the construction industry (building houses or buildings) and in creating or moving heavy things.

Ornamental plant

An **ornamental plant** is decorative: it is grown for how it looks, and not for other values. The term is often shortened to **ornamental**, used as a noun

Ornamental plants are plants that are grown for decoration. They are on display in gardens, landscapes and inside houses. They can be used indoors as cut flowers or potted plants. The cultivation of ornamental plants comes under floriculture and tree nurseries, which is a major branch of horticulture.

Ornamental plants are usually grown in the flower garden, or as house plants. They are usually grown for the display of their flowers. Other common ornamental features include leaves, scent, fruit, stem and bark. In all cases, their purpose is for the enjoyment of gardeners and visitors. Ornamental plants may be used for landscaping, and for cut flowers. The cultivation, called floriculture, is a major branch of horticulture. 

Ornamental plants come in a range of shapes, sizes and colours suitable to a broad array of climates, landscapes, and gardening needs. They are also often chosen for specialised looks or feels in landscape gardening.

Darwin was deeply interested in plants all his life. Several of his books are on plant physiology, and orchids were a passion for him.

Outstanding gardens can be an attraction for visitors. The white garden at Sissinghurst Castle was created by poet and writer Vita Sackville-West (18921962), and is still bringing in the paying visitors.

Bearing (mechanical)

A **bearing** is a device to let fixed directional motion between two parts, typically rotation or linear movement. Bearings may be broadly grouped by the way they work. The most common of the many types are plain bearings and rolling-element bearings. 

The two main types of rolling-element bearings are ball bearings and roller bearings. In ball bearings, the rolling elements are spherical balls. In roller bearings, the rolling elements are cylindrical, taper or spherical rollers. Ball bearings are shown in the pictures. 

Bearings are used in machines that need to spin or move separately, like the rotor in a wind turbine. Egyptians used a form of roller bearing to build the Pyramids.

Free good

In economics **free good** means a good that is available without production, and therefore not scarce.  It is available in as much quantity as desired, with zero opportunity cost to society.

A good that is made available at zero price is not necessarily a free good.  For example, a shop might give away its stock in its promotion, but for the production of these goods, resources were needed, so this would not be a free good in an economic sense.

There are three main types of free goods:

*Resources that are so abundant in nature that there is enough for everyone to have as much as they want.  An example of this is the air that we breathe.

*Resources that are jointly produced.  This type of free good is produced as a by-product of something else that is more valuable.  Waste products from factories and homes, such as discarded packaging, are often free goods.

*Ideas and works that can be copied at zero cost, or almost zero cost.  For example, if someone invents a new device, many people could copy this invention, with no danger of this "resource" running out.  Other examples include computer programs and web pages.

Intellectual property laws have the effect of converting some goods to scarce goods by law. Although these goods are free goods (in the economic sense) when they have been produced, they did require scarce resources, such as artistic skill, to create them in the first place.  Thus, intellectual property laws such as copyrights and patents are sometimes used to give exclusive rights to the creators of such "intellectual property", to make sure that people are interested in these activities.

Many futurists theorize that advanced nanotechnology with the ability to automatically turn any kind of material into any other combination of equal mass, will make all goods essentially free goods, since all raw materials and manufacturing time will become perfectly interchangeable.
Hoist

A **hoist** is a device used for lifting or lowering a load by means of a drum or lift-wheel around which rope or chain wraps. It may be manually operated, electrically or pneumatically driven and may use chain, fiber or wire rope as its lifting medium. The load is attached to the hoist by means of a lifting hook.

A "hoist" normally is used for lifting (near vertical) and a winch is normally used for pulling (near horizontal).

Construction sites, especially for buildings of more than five floors in height, often employ hoists to lift workers and building materials.

## Types of Hoist 
The basic hoist has two important characteristics to define it: Lifting medium and power type. The lifting medium is either wire rope, wrapped around a drum, or load-chain, raised by a gear-like wheel. The power type can be either electric motor or air motor. Both the wire rope hoist and chain hoist have been in common use since the 1800s.

Celts

The **Celts** were a large group of Indo-European tribes in Europe. They first appeared in the early Iron Age, around 1200 B.C. in Austria.  The name 'Celt' comes from the Greeks.  The Romans called them "Gauls". They came from the Hallstatt and La Tène cultures. Their culture spread through much of Europe, and by the time the Greeks and later the Romans started emerging, the British Isles and parts of western, southern and eastern Europe were Celtic - the most prominent Celtic tribes were in Gaul. The Celts spoke Celtic languages. Today, the Celtic languages that remain are the Breton, Cornish, Welsh and Gaelic languages.

Celtic society and technology, although not as advanced as the Romans, was far from being primitive for its time. The Celts lived a way of life based on ethical codes and honor codes and had developed a culture of their own, full of unique drawings, sculptures, jewellery, folklore, and building designs and techniques. They were also skilled in blacksmithing, farming and diplomacy.

Celtic warriors would wear war paint and try to scare their enemies by shouting war cries.  Tribes had different dress standards for battle; some warriors wore chainmail and/or leather armor, some wore only clothes and some were known to fight fully naked.  They also had their own type of sword that was very strong and a shield that was very protective. 

When the Roman Republic started expanding, the Gauls and the Romans became very hostile towards each other and clashed on many occasions; however, the Romans were eventually able to defeat them and ended up conquering most of the Celtic tribes in Europe and ruled them until the fall of the Western Roman Empire.  Celtic tribes also fought among each other.  After winning a battle, the Celts would cut off the heads of their enemies and take them home.

During the fall of the Roman Empire most of the old Celtic land ended up being ruled by migrating Germanic tribes and they merged with Romano-Celtic stock (people with both Roman and Celtic ancestry) to eventually form several European nations of today e.g. Portugal, Spain, France, Belgium, Switzerland, Luxembourg as well as Southern and Western Germany. Territories that are still considered Celtic are Ireland, Wales, Scotland, Isle of Man, Cornwall and Brittany.

Basingstoke

**Basingstoke** is a large town in Hampshire, England. It is  southwest of London,  northeast of Southampton,  southwest of Reading and  northeast of Winchester. In 2008 it had an estimated population of 82,913. It is part of the borough of Basingstoke and Deane. Basingstoke is often nicknamed "Doughnut City" or "Roundabout City" due to the number of roundabouts.

Often mistaken for a "new town", Basingstoke is an old market town expanded in the 1960s as part of a plan of London County Council, Hampshire County Council and Basingstoke Borough Council. It was developed fast to accommodate part of the London 'overspill' as seen in the Greater London Plan, 1944.
