Semiconductors were being studied in laboratories as early as the 1830s. In 1833 Michael Faraday was experimenting with silver sulfide. He discovered that as the material was heated it conducted electricity better. This was the opposite of how copper acted. When copper is heated it conducts less electricity. A number of other early experimenters discovered other properties of semiconductors. In 1947 at Bell Labs in New Jersey, the transistor was invented. This led to the development of integrated circuits, which power almost all electronic devices today.
Doping is the process of adding a small impurity to a pure semiconductor to change its electrical properties. Lightly and moderately doped semiconductors are called extrinsic. A semiconductor doped to such high levels that it acts more like a conductor than a semiconductor is referred to as degenerate. Most semiconductors are made out of silicon crystals. Pure silicon has little use but doped silicon is the basis for most semiconductors. Silicon Valley was named for the large number of semiconductor startup companies that were located there.
Today, semiconductors are used far and wide. Semiconductors can be found in nearly every electronic device. Desktop computers, the Internet, tablet devices, smartphones all would not be possible without semiconductors.
Semiconductors can be made into very precise switches with a small amount of voltage. The voltage that the semiconductor doesn’t need can be sent to other electrical components in the device. Semiconductors can also be made very tiny and many of them can fit into a rather small circuit. Since they can be made so small, electrical devices today can be made thin and lightweight without compromising processing power.
Some of the dominating companies in the semiconductor business are Intel Corporation, Samsung Electronics, TSMC, Qualcomm and Micron Technology.

Curium is a transuranic element. It is a radioactive element that does not exist in nature. Curium has to be made in a lab. Curium has a silver color and it is made by bombarding a plutonium target with alpha particles (helium ions). Curium was named after Marie Curie and her husband Pierre.
Lanark
Lanark is a town in South Lanarkshire, Scotland. It is close to Carluke and Biggar. Lanark is approximately 40 miles from Edinburgh, the capital of Scotland. William Wallace once lived there. There is a statue of Wallace on the town church. A plaque remembers where he "first drew sword to free his native land" in 1296, when he killed Heselrig, the English sheriff of Lanark. This event forms the start of the Mel Gibson film, "Braveheart".
Lanark is also notable for its annual Lanimer celebrations, where local children on coloured floats parade through the streets along with marching pipe bands. A Lanimer Queen is elected from the children, and crowned in a ceremony at the foot of the High Street. A Lord Cornet is chosen from local businessmen, and acts as escort for the Queen for the events of Lanimer Week.
Robert I of Scotland
Robert I of Scotland (11 July 1274 – 7 June 1329) was King of Scotland from 1306 to 1329. He is better known as Robert the Bruce, or simply The Bruce. He is famous for beating the English army at the Battle of Bannockburn near Stirling in 1314.
Robert the Bruce was born at Turnberry Castle on 11 July 1274. He was the oldest son of the sixth Robert Bruce and Marjorie, the Countess of Carrick.
Robert the Bruce's family originally came from France. They were from a place called Brus in Normandy, which is in the northern part of France. An ancestor also named Robert de Brus came to England with William the Conqueror in 1066. Another Robert de Brus came to Scotland with David I of Scotland and his family became powerful lords.
In 1286, King Alexander III of Scotland died. His granddaughter was supposed to become Queen of Scotland, but she died too. In 1292 the Bruce family and another family called the Balliols (BAY-lee-ols) asked King Edward I of England to decide who would become the new king. King Edward chose John Balliol.
In 1292 Robert's family decided that he should be the head of all the Bruces in Scotland. In 1297, King Edward I of England wanted Scotland go to war against France. Many Scottish leaders said no and against the English king. Robert joined this rebellion. Edward won most of the battles against the Scottish rebels. Finally Robert ended up doing what Edward wanted.
In 1306, Robert the Bruce met a man called John Comyn (KOHM-in) in a church. John Comyn also wanted to be King of Scotland. They had an argument and Robert killed John. Soon after, Robert went to Scone (skoon), and the Scottish lords brought out the royal clothes that they had hidden from the English. Then Robert was crowned King of Scots.
Robert the Bruce then fought a lot of battles to make Scotland free instead of always doing what the English king wanted. He fought King Edward I, and then his son, King Edward II. In 1314, Robert the Bruce's army defeated Edward II's army at the Battle of Bannockburn.
In 1315, Robert the Bruce sent his army to Ireland. At that time the English were in control of Ireland. Robert fought with them and made his brother, Edward Bruce, High King of Ireland in 1316. The Scottish army did not treat the Irish people well, and they were forced to leave after Edward Bruce was killed in 1318.
On June 7th, 1329, Robert the Bruce died. After a life of fighting he had wanted to redeem himself by joining the Crusades. Realizing he could not accomplish this he sent his trusted friend Sir James Douglas to take his heart in a small silver box on crusade. James Douglas took the heart and with several knights left on their journey to honor Robert's request. But in fighting in Spain Sir James was killed and the heart was returned to Scotland. the Bruce's body is buried in Dunfermline Abbey, while his heart is buried in Melrose Abbey.
Robert did not want any fighting over his kingdom after he died. He provided for his brother Edward Bruce to follow him as king. But after Edward died in 1318 Robert's heir became his son David who became king as David II of Scotland. Following David, Robert's grandson Robert II Stewart by his daughter Marjorie was heir to the throne king as Robert II of Scotland. He left behind him a well-ordered kingdom.
In 1295 Robert married Isabella of Mar, daughter of Donald, 6th Earl of Mar. Together they had a daughter:
In 1302 Robert married his second wife Elizabeth de Burgh. She was the daughter of Richard de Burgh, Earl of Ulster Together they had:
Robert also had several illegitimate children.

Elementary particle
In physics, an elementary particle or fundamental particle is a particle that is not made of other particles.
An elementary particle can be one of two groups: a fermion or a boson. Fermions are the building blocks of matter and have mass, while bosons behave as force carriers for fermion interactions and some of them have no mass. The Standard Model is the most accepted way to explain how particles behave, and the forces that affect them. According to this model, the elementary particles are further grouped into quarks, leptons, and gauge bosons, with the Higgs boson having a special status as a non-gauge boson.
Of the particles that make up an atom, only the electron is an elementary particle. Protons and neutrons are each made of 3 quarks, which makes them composite particles, particles that are made of other particles. The quarks are bound together by the gluons. The nucleus has boson pion fields responsible for the strong nuclear force binding protons and neutrons against the electrostatic repulsion between protons. Such virtual pions are composed of quark antiquark pairs again held together by gluons.
There are three basic properties that describe an elementary particle: ’mass’, ’charge’, and ’spin’. Each property is assigned a number value. For mass and charge the number can be zero. For example, a photon has zero mass and a neutrino has zero charge. These properties always stay the same for an elementary particle.
Mass and charge are properties we see in everyday life, because gravity and electricity affect things that humans see and touch. But spin affects only the world of subatomic particles, so it cannot be directly observed.
Fermions (named after the scientist Enrico Fermi) have a spin number of ½, and are either quarks or leptons. There are 12 different types of fermions (not including antimatter). Each type is called a "flavor". The flavors are:
Six of the 12 fermions are thought to last forever: up and down quarks, the electron, and the three kinds of neutrinos (which constantly switch flavor). The other fermions "decay". That is, they break down into other particles a fraction of a second after they are created. Fermi-Dirac statistics is a theory that describes how collections of fermions behave.
Bosons, named after the Indian physicist Satyendra Nath Bose, have spin 1. Although most bosons are made of more than one particle, there are two kinds of elementary bosons:
The photon and the gluons have no charge, and are the only elementary particles that have a mass of 0 for certain. The photon is the only boson that does not decay. Bose-Einstein statistics is a theory that describes how collections of bosons behave. Unlike fermions, it is possible to have more than one boson in the same space at the same time.
The Standard Model includes all of the elementary particles described above. All these particles have been observed in the laboratory.
The Standard Model does not talk about gravity. If gravity works like the three other fundamental forces, then gravity is carried by the hypothetical boson called the graviton. The graviton has yet to be found, so it is not included in the table above.
The first fermion to be discovered, and the one we know the most about, is the electron. The first boson to be discovered, and also the one we know the most about, is the photon. The theory that most accurately explains how the electron, photon, electromagnetism, and electromagnetic radiation all work together is called quantum electrodynamics.

Spin (physics)
In physics, spin is the constant rotation of an object.
For large visible objects like the Earth, spin is the angular momentum of the turning of the Earth around its axis. This tells the amount of rotation that it has. Angular momentum changes with the mass and shape of the object, and with how fast it is turning.
Experiments such as the Stern-Gerlach experiment have shown that sub-atomic particles, such as electrons, seem to have a north pole and a south pole much like magnets do. Scientists once thought that this was caused by the particle spinning on its axis like a planet.
Later, it was shown that the electron would have to be spinning faster than the speed of light to do this. This is why scientists no longer believe that the electron is actually spinning like a planet. Scientists do, however, continue to refer to the magnetic properties of particles as "spin".
Spin, whatever it is, seems to follow some of the laws of angular momentum, but not all of them. A "spinning" electron (or any other sub-atomic particle with spin) can only have certain values of angular momentum. Electrons can also align themselves against a magnetic field in ways that would be impossible in the everyday world.
Spin is considered a fundamental property of any particle.
Bendigo, Victoria
Bendigo is a city in central Victoria, Australia. There are about 86,000 people in Bendigo. It is the fourth biggest city in Victoria after Melbourne, Geelong and Ballarat. The city area is and has the towns Bendigo, Marong, Lockwood, Lockwood South, Ravenswood, Sebastian, Elmore, Heathcote, Maiden Gully, Lake Eppalock, Axedale, Goornong, Raywood and Huntly, all together, there are 100,000 people living there.
Strathfieldsaye is a small suburb in Bendigo. It takes its name from Stratfield Saye House, which was awarded to the Duke of Wellington after his defeat of Napoleon at the Battle of Waterloo. In the 2011 census, Strathfieldsaye had a population of 4,648.
Ballarat, Victoria
Ballarat is a city in central Victoria, Australia. Nearly 90,200 people live there, which makes it the third biggest city in Victoria, after Melbourne and Geelong. It is also the biggest city that is not on the coast in Victoria. It is about north-west of Melbourne. The city area covers about .
Tribes of Australian Aborigines, the Wathaurang and the Borneghurk, used to rest here, and called it "Balla-arat" meaning "Resting - Place"
The first people from Europe came to Ballarat in 1837 to be sheep farmers. They took over large areas of land, with some farms more than . By 1840 there were more than 20 farms with thousands of sheep in the Ballarat area. The city area was a farm owned by William Cross Yuille and Henry Anderson who arrived in 1838.
Gold was found at Ballarat in late August 1851, by James Regan and John Dunlop and within three weeks there were nearly 1000 people digging in the area looking for gold. In two days the Cavanagh brothers dug up of gold from a hole less than two metres deep. This area is now called "Golden Point". Within a year there were 20,000 people living in Ballarat. With so many people coming to look for gold, the town soon became bigger. The Post Office opened on November 1, 1851.
Ballarat is famous as the site for an uprising, or rebellion. This is known as the Eureka Stockade or the Eureka Rebellion, which took place on 3 December 1854. About 30 miners were killed. This is an important moment in Australian history. The site now has a museum, called the Eureka Centre, with displays about the rebellion. The rebel miners flag, the Eureka Flag can be seen at the Ballarat Fine Art Gallery.
Gold mining made Ballarat a rich town, and it was made a city in 1871. The railway came to the town with the opening of the Geelong-Ballarat line in 1862, and a direct line to Melbourne finished in December 1889.
The money made from gold mining can still be seen in size of many public buildings, the large parks, wide streets, the grand style of shops and hotels, and large houses built for the wealthy residents. From the 1880s to the start of the 20th century the city changed from a gold rush town to a large industrial city. Factories that made equipment for mining slowly changed into engineering and manufacturing businesses. The Victorian Railways built the Ballarat North Workshops in April 1917.
During 1901, the Duke of Cornwall and York, later King George V, opened the first Commonwealth Parliament in Melbourne. While in Victoria, the Duke and Duchess made several journeys by train, on 13 May they went from Melbourne to Ballarat via Geelong, returning to Melbourne via Bacchus Marsh. Ballarat's airport was opened in 1930.
In 1940 the Federal Government took over the airport as an air base for the Empire Air Training Scheme. During WWII the base was a RAAF Wireless Air Gunners' School as well as the base for USAAF Liberator bomber squadrons. During the war the airport was made much bigger, with three sealed runways. Two of these were over 2,000 metres (6,550 ft) long and 45 metres (150 ft) wide. The aerodrome remained the RAAF School of Radio until 1961 when it was returned to normal use. The City of Ballarat now runs the airport which is listed on the Victorian Heritage Register for its social and historic importance.
After World War II, Ballarat grew to the northwest. To ease the housing shortage a large estate was built by the Housing Commission of Victoria on the old Ballarat Common This area is now called Wendouree West. From 1951 to 1962, 750 houses were built, with another 300 added in the 1970s. This was matched by private housing built in Wendouree.
In the 1980s the areas of growth have been in the south and west of the city, as well as new building in the inner areas of the city. Through the 20th century Ballarat continued to grow at a steady rate. New public buildings have been built including the hospital, the library, the law courts and the police station complex. Ballarat is home to many schools, including Damascus College.
Heimdall (or Heimdallr) is one of the gods in Northern mythology. He is the guardian of the Bifröst Bridge. He was the son of nine different mothers and was called the "White God".
Heimdall is the guardian of the gods. He will blow a horn, called the "Gjallarhorn", if Asgard is in danger. His senses are so good that he can hear the grass grow and he can see to the end of the world. Heimdall could hear a leaf fall. He does not need any sleep at all.
Heimdall was said to be the last of the gods to die at Ragnarok when he and Loki would kill one another.

Anaheim Ducks
The Anaheim Ducks are an ice hockey team from Anaheim, California. They are in the National Hockey League (NHL). The Ducks changed the name on June 22, 2006. They used to be the Mighty Ducks of Anaheim. The name comes from the Disney movie "The Mighty Ducks".
The team was created in 1991 and started playing in the 1993 season. The Ducks were originally owned by The Walt Disney Company. In 2005, Disney sold the Ducks to Susan and Henry Samueli
They are in the Western Conference's Pacific Division. They play their home games at Honda Center, in Anaheim, California. Their team colors are black, gold, and orange. Dallas Eakins is the team's head coach. Ryan Getzlaf is the captain of the team.
To date, they have won one Stanley Cup. It was in the 2006-2007 season. The Anaheim Ducks won the conference championship in the 2002-03 season and 2006-2007 season. They have won 6 Pacific division titles.
Móði and Magni
Magni and Móði (Old Norse: "strength" and "bravery") are a pair of minor deities in Norse mythology. They are sons of the god Thor, said to be embodiments of their father's traits. While Magni is born to Thor by the jötunn Járnsaxa (a lover of Thor), the name of Móði's mother is unknown.
Other than his part after Ragnarök, little is known about Móði. Magni however, is featured prominently in the myth of Thor's battle with the giant Hrungnir.
Thor hit the giant Hrungnir in the head with his hammer, Mjölnir, shattering Hrungnir's skull. The giant then fell dead, as his leg landed on Thor's neck, pinning the god to the ground. The other Æsir tried to lift Hrungnir's leg off of Thor, but were unsuccessful. Thor's son, Magni, who was only three days old at the time, then came to his father and lifted Hrungnir's leg off of Thor all by himself. In his gratitude, Thor gifted his son Hrungnir's horse, Gullfaxi (Old Norse: "Gold-mane"). Odin himself was upset that Thor gave the horse to "the son of a giantess" and not to Odin, Thor's own father.
Kerosene or paraffin oil is a colourless flammable liquid, usually used for fuel. Kerosene is made by fractional distillation of petroleum. It may be used as fuel for lamps, in some kinds of cooking stoves, and in heaters. Kerosene is mainly used in the fuel for jet engines. The most common consumer use for kerosene in Canada and the US is lighting camp lamps. Kerosene is used as cooking fuel in India. Kerosene is also used for making ketamine
Brass instrument
A brass instrument is a musical instrument that you play by blowing through a mouthpiece to change the pitch, or note.
Brass players use their breath to produce sound. Instead of blowing into a reed, they vibrate their lips by buzzing them against a metal cup-shaped mouthpiece. The mouthpiece helps to amplify the buzzing, which creates the sound. Most brass instruments have valves attached to their long pipes; the valves look like buttons. Pressing on the valves makes them open and close different parts of the pipe.
With brass instruments, the sound starts at the lips.
Their mouthpieces just help your lips buzz. It does not matter if the instrument is really made of brass, as long as it works that way.
It is not important what the instrument is made of. Some brass instruments are really made of wood, but are still called brass instruments, like the serpent. Other instruments are made of brass but do not work like this, like the saxophone. They are not called brass instruments, because they don't work that way.
There are also parts of the instrument that change the resonance and thus the pitch, like slides or valves.
A brass band is a group of brass instruments and drums that play music together. They are often used to play for parades and processions because the players can march and play at the same time. Brass bands were very popular in England. Many factories and coal mines had their own bands. The workers would play in the bands after work. One famous band is the Grimethorpe Colliery Band.
Crystallization is the way that atoms link up in a regular structure. The structure is held together by chemical bonds or connected groups. Crystallization can be from a melt or from a solution, and can be natural or artificial. Rarely, crystal can form directly from a gas. Faster crystallization makes smaller size crystals as in basalt, and slower can make bigger crystals, as in granite.
Crystallization occurs in two major steps. The first is "nucleation". This is the appearance of a crystalline phase from a supercooled liquid or a supersaturated solvent. The second step is "crystal growth". This is the increase in the size of particles: it leads to a crystal state. Loose particles form layers at the crystal's surface and lodge themselves into open pores, cracks, etc.
Artificial crystallization is a technique to get solid crystals from a homogeneous solution. For crystallization to occur the solution should be supersaturated. Put simply, the solution should contain more solute molecules than it would under ordinary conditions. This can be achieved by various methods—solvent evaporation, cooling, and chemical reaction.
To make things clear we can use a simple example. We take a bowl of water to which we add sugar crystals. We keep adding sugar to it until we reach a stage when no more crystals can be dissolved. This solution is now a saturated one. It is interesting to note that we can dissolve more crystals to this particular saturated solution by heating it. Solubility of solutes increases with increase in temperature, but there are exceptional cases. This increase in temperature causes more sugar crystals to dissolve (so forming a supersaturated solution), but when the temperature of the solution cools down, the solubility of the solute decreases This is because the temperature of the solution has decreased, and the 'excess' sugar crystallizes out. This process illustrates the simplest of supersaturation techniques.
'Drowning' is the addition of a nonsolvent in the solution that decreases the solubility of the solid. Alternatively, chemical reactions can also be used to decrease the solubility of the solid in the solvent, thus working towards supersaturation.
Crystallization can be divided into stages primary nucleation is the first. It is the growth of a new crystal. In turn this causes secondary nucleation – the final stage if removal of the crystals is not an issue. Secondary nucleation needs existing crystals to continue crystal growth. In our sugar example, we had got such nuclei when the 'excess' sugar had just about crystallized out. Secondary nucleation is the main stage in crystallization for this is what causes the 'mass production' of crystals.

Cairns, Queensland
Cairns is a city in Queensland, Australia. 120.000 people live there. Cairns is about 1720 km (1,069 miles) north of Brisbane and about 2500km (1,553 miles) from Sydney by road. It is built on the shores of Trinity Bay.
Cairns is an important travel destination for tourists because it is warm all year round and is near many attractions. The Great Barrier Reef is only one-and-a-half hours away by boat. The Daintree National Park and Cape Tribulation, about 130km north of Cairns, are popular areas for experiencing a tropical rainforest. It is also a starting point for people wanting to see Cooktown, Cape York Peninsula, and the Atherton Tableland.
Captain James Cook named Trinity Bay when he arrived there in his ship HM Bark Endeavour on Trinity Sunday, 1770. The first Europeans to settle arrived in 1876 when gold was found near Cairns. It was named after the Governor of Queensland, Sir William Cairns.
Arabian Sea
The Arabian Sea is the northwest part of the Indian ocean. To its west are the Guardafui Channel, Somali Sea and Arabian peninsula. To its east is the Indian peninsula. It covers around 4,600,000, km. The Arabian Sea one of the warmest seas.
The International Hydrographic Organization defines the limits of the Arabian Sea as follows:
Border and Basin countries:
The Arabian Sea historically and geographically has been referred to with different names by Turks, persian , Arabs and scholars of Geography and cartography in medieval Islam, European geographers and travelers, including
Indian Sea, Sindhu Sagar, Erythraean Sea, Persian Sea . and green Sea. In Indian folklore, it is referred to as Darya, Sindhu Sagar, and Arab Samudra.
Arab sailors and nomads used to call this sea by different names, including the green sea, Bahre Fars, the ocean sea, the Hindu sea, the Makran Sea, the sea of Oman, among them the Zakariya al-Qazwini, Al-Masudi , Ibn Hawqal and (Hafiz-i Abru) They wrote: “The green sea and Indian sea and Persian sea are all one sea and in this sea there are strange creatures. .
Ibn Khordadbeh ,Ibn Sa'id al-Maghribi , Muhammad al-Idrisi, Istakhri, Mahmud al-Kashgari, Khashkhash Ibn Saeed Ibn Aswad and Muhammad ibn Musa al-Khwarizmi had mentioned the sea as Persian sea and Bahr e Fars.
Many atlases had published old maps of Asia and Indian ocean such as Atlas of The Arabian Peninsula in Old European Maps.Paris, 424pp. contains 253 maps.10 maps have used persian Sea (for the body of water which is now called Arabian sea)the maps in pages: -141-226-323-322-331-345-347-363-355• such as the hours shape map of Bunting H.S.Q34/24CM Hanover,1620. .
Base (chemistry)
A base is a substance that can accept a hydrogen ion (H+) from another substance. A chemical can accept a proton if it has a negative charge, or if the molecule has an electronegative atom like oxygen, nitrogen, or chlorine that is rich in electrons. Like acids, some bases are strong and others are weak. The weak bases are less likely to accept protons, while the strong bases quickly take protons in solution or from other molecules.
An acid is a base's "chemical opposite". An acid is a substance that will donate a hydrogen atom to the base.
Bases have a pH greater than 7.0. Weak bases generally have a pH value of 79 while strong bases have a pH value of 9–14.
Bases can be used to neutralize acids. When a base, often OH, accepts a proton from an acid, it forms a water molecule which is harmless. When all of the acids and bases react to form water molecules and other neutral salts, it is called neutralization. Acids can also be used to neutralize bases.
Every base has a conjugate acid formed by adding a hydrogen atom to the base. For example, NH (ammonia) is a base and its conjugate acid is the ammonium ion, NH. A weak base forms a strong conjugate acid and a strong base forms a weaker conjugate acid. Since ammonia is a moderately strong base, ammonium is a considerably weaker acid.
Bases have these characteristics:
Some common household products are bases. For example, caustic soda and drain cleaner are made from sodium hydroxide, a strong base. Ammonia or an ammonia-based cleaner such as window and glass cleaner, is basic. These stronger bases may cause a skin irritation. Other bases, like cooking ingredients sodium bicarbonate (baking soda) or cream of tartar are basic, but these are not harmful and suitable for cooking.
Gloves should always be worn when handling bases. If skin irritation is encountered, the affected area should be rinsed thoroughly with cold water. If that does not stop the problem, contact medical help as soon as possible.
A strong base is a base that gives off a hydroxide ion, OH–, when put in water. There are eight of them.
Ytterbium
Ytterbium is a chemical element. It has the chemical symbol Yb. It has the atomic number 70. It is part of a group of chemical elements in the periodic table named the Lanthanides. Ytterbium is a rare earth element. It is soft and silver in colour.
Ytterbium is found in minerals named gadolinite, monazite, and xenotime. In nature it is found as a mix of seven stable isotopes. Ytterbium is used in some steels and is also used to make lasers.
Heart transplant
A heart transplant is a type of surgery where someone's heart is removed and another one is put in because theirs is not working properly. The new heart is taken from a dead person who does not need it any more. The first heart transplant on a human was done by Christiaan Barnard in December 1967.
Joan Chandos Baez (born January 9, 1941) is an American folk singer and activist. Baez is known for her very individual vocal style. She is a soprano with a three-octave vocal range. Many of her songs talk about social issues.
She is best known for her 1970s hits "Diamonds & Rust" and "The Night They Drove Old Dixie Down". She is also known for "Sweet Sir Galahad" and "Joe Hill." She sang these songs at the 1969 Woodstock festival and the songs became famous. She is also well known due to her relationship with Bob Dylan and her love for activism in areas such as nonviolence, civil and human rights and the environment.
Baez has performed for nearly fifty years. She has released over thirty albums. She has recorded songs in over eight languages. Baez is considered a folksinger, but after the 1960s her music became a lot different from folk. She sings many kinds of music, including rock, pop, country, and gospel. Baez is famous for singing other peoples' songs very differently. She sang songs by The Beatles, Jackson Browne, Paul Simon, The Rolling Stones, Stevie Wonder and many others.
Baez protests against social and environmental problems. She did not support the Vietnam War. She did not want people to pay taxes that paid for the Vietnam War. Baez did not want men going to fight in the war. She did not perform in places where people of color were treated differently. In addition, Baez helped found the Resource Center for Nonviolence. The Resource Center for Nonviolence is an organization whose goal is to make social change without violence.
Kalmar Union
The Kalmar Union was a historical consisting union of the kingdoms of Denmark, Norway and Sweden, and various other provinces and areas. At that time, Norway included Iceland, Greenland, the Faroe Islands, Shetland, Orkney, and parts of Finland belonged to Sweden. The union was started in 1397 at a meeting in the town of Kalmar in Sweden. The union ended on 6 June 1523 when Sweden left the union by Gustav I.
Bay of Plenty
The Bay of Plenty is a region in New Zealand. It was first called the Bay of Plenty by Captain James Cook in November 1769. The Māori name for the bay is "Te Moana-a-Toi" ("the sea of Toi").

Accounting or accountancy is the job of sharing financial information about a business to managers and shareholders (people who have invested in the business). Accounting is often called the "language of business". Accountants are people who do accounting, and also carry out the auditing or checking of a company's books and records. In Britain, this auditing is often carried out by a qualified person called a "chartered accountant". In the United States, the professional designation is Certified Public Accountant or "CPA".
When accountants do accounting work, they write in the books of account (ledgers) that belong to a company. Every time money is spent or earned, it is written in the ledger. The information in the ledger is used to prepare the company accounts monthly, quarterly (every three months) and annually (every year). These annual accounts show what money the company has taken in over time and what it has spent money on. It also shows if the company made a profit in the year (if it made more money than it spent), who owes the company money, who the company owes money to, and any big expensive items the company has bought which they expect to use for many years. Lenders, managers, investors, tax authorities (the people who collect taxes for the government) and other decision-makers look at these annual accounts. Managers and investors look at the ledger and make decisions about how to spend money in the future. Lenders like banks look at the accounts before they lend money to the company. Tax authorities look at them to check that the company is paying the correct amount of taxes.
The word "accountant" originally comes from the Latin word "computare" – "to reckon, count, number", via French.
"Accomptant" was the original spelling and pronunciation of the word "accountant". However, over time, people began to drop the "p" in the word "accomptant". Over time, the word changed both in the way it was said and spelled to how it is today.
The basic accounting equation is assets=liabilities+equity.
Accountancy is very old. It started when humans first started to farm and form towns and cities. People who thought about economics (keeping track of money and valuable things) thought of a way to write down the sizes and values of crops.
The earliest accounting records were found among the ruins of ancient Babylon, Assyria and Sumeria, which are more than 7,000 years old. The people of that time relied on primitive accounting methods to record the growth of crops and herds. Because there is a natural season for farming and herding, it is easy to count and determine if a surplus had been gained after the crops had been harvested or the young animals weaned.
The invention of a form of bookkeeping using clay tokens represented a huge cognitive leap for mankind.
In the twelfth-century A.D., the Arab writer, Ibn Taymiyyah, wrote a book called "Hisba". This book has details about accounting systems that were used by Muslims before the mid-seventh century A.D. Muslim accounting was influenced (changed) by Romans and Persians. In his book, Ibn Taymiyyah gives details of a complex governmental accounting system.
The "Res Gestae Divi Augusti" (Latin: "The Deeds of the Divine Augustus") is a remarkable account to the Roman people of the Emperor Augustus' stewardship. It listed and quantified his public expenditure, which encompassed distributions to the people, grants of land or money to army veterans, subsidies to the "aerarium" (treasury), building of temples, religious offerings, and expenditures on theatrical shows and gladiatorial games. It was not an account of state revenue and expenditure, but was designed to demonstrate Augustus' munificence. The significance of the "Res Gestae Divi Augusti" from an accounting perspective lies in the fact that it illustrates that the executive authority had access to detailed financial information, covering a period of some forty years, which was still retrievable after the event. The scope of the accounting information at the emperor's disposal suggests that its purpose encompassed planning and decision-making.
The Roman historians Suetonius and Cassius Dio record that in 23 BC, Augustus prepared a "rationarium" (account) which listed public revenues, the amounts of cash in the "aerarium" (treasury), in the provincial "fisci" (tax officials), and in the hands of the "publicani" (public contractors); and that it included the names of the freedmen and slaves from whom a detailed account could be obtained. The closeness of this information to the executive authority of the emperor is attested by Tacitus' statement that it was written out by Augustus himself.
Records of cash, commodities, and transactions were kept scrupulously by military personnel of the Roman army. An account of small cash sums received over a few days at the fort of Vindolanda circa 110 CE shows that the fort could compute revenues in cash on a daily basis, perhaps from sales of surplus supplies or goods manufactured in the camp, items dispensed to slaves such as "cervesa" (beer) and "clavi caligares" (nails for boots), as well as commodities bought by individual soldiers. The basic needs of the fort were met by a mixture of direct production, purchase and requisition; in one letter, a request for money to buy 5,000 "modii" (measures) of "braces" (a cereal used in brewing) shows that the fort bought provisions for a considerable number of people.
The Heroninos Archive is the name given to a huge collection of papyrus documents, mostly letters, but also including a fair number of accounts, which come from Roman Egypt in 3rd century CE. The bulk of the documents relate to the running of a large, private estate is named after Heroninos because he was "phrontistes" (Koine Greek: manager) of the estate which had a complex and standarised system of accounting which was followed by all its local farm managers. Each administrator on each sub-division of the estate drew up his own little accounts, for the day-to-day running of the estate, payment of the workforce, production of crops, the sale of produce, the use of animals, and general expenditure on the staff. This information was then summarized as pieces of papyrus scroll into one big yearly account for each particular sub—division of the estate. Entries were arranged by sector, with cash expenses and gains extrapolated from all the different sectors. Accounts of this kind gave the owner the opportunity to take better economic decisions because the information was purposefully selected and arranged.
Luca Pacioli (1445–1517), also known as Friar Luca dal Borgo, is said to be the "Father" of accountancy. He wrote a textbook in Latin called "Summa de arithmetica, geometrica, proportioni et proportionalita" ("Summa on arithmetic, geometry, proportions and proportionality", Venice 1494). This textbook was used in the abbaco schools in northern Italy. Sons of merchants and craftsmen were taught in these schools. This textbook was written about math. It has the first printed description of how merchants from Venice kept their accounts. Merchants from Venice used a system called the double-entry bookkeeping system.
Double-entry bookkeeping is where there is a debit and credit entry for every transaction.
Pacioli wrote down this system but he did not invent it, but he is still called the "Father of Accounting". The system he wrote had most of the accounting cycle as it is known today. He wrote about using journals and ledgers, and warned that a person should not go to sleep at night until the debits were the same as the credits. His ledger had accounts for assets (things that have value), liabilities (debts and loans that are to be paid to someone else), capital (money), income and expenses. He showed how to write year-end closing entries and suggested that a trial balance be used to prove that a ledger is balanced. His treatise (long essay) in the book also has info about other topics, such as accounting ethics and cost accounting.
The first book written in the English language on accounting was published in London, England by John Gouge in 1543.
In 1588 John Mellis from Southwark, England wrote a short book of instructions for keeping accounts.
There was another book written in 1635 that was described as "The Merchants Mirrour, or directions for the perfect ordering and keeping of his accounts formed by way of Debitor and Creditor". This book was written by Richard Dafforne, who was an accountant. This book has many references to books about accountancy that were written much earlier. One chapter of this book is titled "Opinion of Book-keeping's Antiquity". In this chapter the author says that, according to another author, the bookkeeping he wrote about was used two-hundred years earlier in Venice.
There were several editions of Richard Dafforne's book. The second edition was published in 1636. The third edition was published in 1656. Another edition was published in 1684. The book is very complete in how it describes scientific accountancy. It contains a lot of detail and explanation. The science that supports accountancy was liked by many people in the seventeenth century. This is supported by the fact that there were so many editions. Starting at this point in history, there have been many books written about accountancy. Many authors claim to be professional accountants and teachers of accountancy. Because of this, it shows that there were professional accountants who were employed in the seventeenth century.
A financial audit is where an internal audit and an external audit are done. For an external audit, an independent (unrelated) auditor takes a look at financial statements and accounting records. By looking at these records, the auditor can find out if these records are true, fair and follow Generally Accepted Accounting Principles (GAAP), or International Financial Reporting Standards (IFRS). "Internal audit" tries to get info for management usage, and is done by employees.

A carbonate is a chemical compound that has the carbonate ion, . This ion is made of carbon and oxygen. The name may also mean an ester of carbonic acid, an organic compound containing the carbonate group C(=O)(O–) of carbon and oxygen. They have a valency of 1.
When added to an acid, a carbonate will produce carbon dioxide, water and a chemical salt. Sedimentary rocks containing calcite and other carbonates are plentiful in the earth.
Antonie Philips van Leeuwenhoek (24 October 1632 – 30 August 1723; last name pronounced 'Layvenhook') was a Dutch tradesman and scientist from Delft, Netherlands. He is best known for his work to improve the microscope.
Using his handcrafted microscopes, he was the first to see and describe single celled organisms, which he originally referred to as "animalcules", and which we now refer to as microorganisms. He was also the first to record microscopic observations of muscle fibers, bacteria, spermatozoa and blood flow in small blood vessels. Van Leeuwenhoek did not write books, but sent letters to the Royal Society in London. The letters were published in the Royal Society's journal "Philosophical Transactions of the Royal Society".
