Denomination (currency)

When dealing with money, denomination is the value of the individual currency. 

For example a one dollar bill, a 100 dollar bill, a penny and a quarter are all different denominations of money. A one dollar bill and a one dollar coin are the same denomination as they are the same value.

Monetary union
When countries form a monetary union, redenomination may be required and the conversion ratio is often not a nice even number, or even less than 1.

Decimalisation
When countries that had a "pound (£) - shilling (s) - pence (d)" (£sd) currency system converted to a system which had pounds (£) and pennies (p) or dollars ($) and cents (¢) it was called decimalisation. In the £sd system, £1 = 20s and 1s = 12d, so £1 = 240d. However in the new systems £1 = 100p or $1 = 100¢ or 100c - a decimal-based system, hence the word "decimalised".

Simulation

A simulation is a way of seeing a thing happen without it actually taking place in the same way. A simulation can be used to predict what might happen without doing it, in case it is dangerous or too expensive or difficult. It can also be used to show people what will happen next, or what happened in the past. It can also show what people believe is happening in a place or time where it is impossible to know what really happens. 

There are research institutions just devoted to simulations, like, e.g., The George E. Brown, Jr. Network for Earthquake Engineering Simulation or NEES.

Simulations are used for many purposes, because in a simulation things can be controlled that might not be easy to control in real life.  They can use smaller versions of an object or system for testing or practice.  Smaller versions of things, like space ships or rooms, can simulate the real thing.  They can also be safer, in place of a thing that is dangerous, like when astronauts practice in a swimming pool rather than in outer space. Astronauts practiced in simulations of the moon before they went and landed there.  They use simulations of spaceships that move the way real spaceships do.  Simulations often use computers.  Computers are used to make simulations of what a spaceship's route might be on the way to the moon, to help plan the mission.

Video games
One type of video game is called simulator games". These games let the player simulate doing different things. For example, in the game Theme Hospital, players perform simulated surgery. SimCity'' lets players design and build their own simulated city.

Ilocos

Ilocos Region is a region in the Philippines. Its regional center is San Fernando, La Union. The region has four provinces: Ilocos Norte, Ilocos Sur, La Union and Pangasinan.

Inhabitants are called Ilocanos and they speak the Ilocano language.

The term Ilocos Region is derived from this term. However, the designation of Ilocos as the basis of the name of the region promotes the wrong notion that all the residents of Region 1 are Ilocanos. Because 28% of the inhabitants are Pangasinan people, who belong to a different ethno-linguistic group from the Ilocanos.

Adventure

An  adventure is something exciting that happens to someone.  An adventure can be a made-up story, or it can be something that happens in real life.

People often like stories about a person or a group of people who go off and have an adventure.  There is often some danger in the story. Enid Blyton and Edgar Rice Burroughs wrote stories about people who have exciting adventures. Harry Potter has lots of adventures: he meets strange people and gets into lots of dangerous situations.

People in real life like to have adventures. They may be explorers who like to go to far-away places where no one has ever been before.

Adventure sports are sports that are exciting and can be rather dangerous. Skydiving, gliding and rock climbing are adventure sports.

An adventure playground is a playground for children where they can climb, swing and jump on things. They have been made by adults for children to use and are normally quite safe.

An adventurer is someone who goes on adventures or does things that are risky.

Space travel is an example of a modern adventure.

An adventure game is a video game about adventures.

The word venture is a short form of "adventure".  A "business venture" is a business project in which there is a lot of risk.  "Venture" can also be a verb: "They ventured out into the storm".

Broom (shrub)

Brooms are a group of evergreen, semi-evergreen, and deciduous shrubs.

All the brooms and their relatives (including Laburnum and Ulex) grow in Europe, north Africa and southwest Asia. The greatest diversity one can find in the Mediterranean region. Many brooms (though not all) are fire-climax species, adapted to regular stand-replacing fires which kill the above-ground parts of the plants, but create conditions for regrowth from the roots and also for germination of stored seeds in the soil.

The most familiar is common broom, that grows in northwestern Europe. One can find it in sunny sites, usually on dry, sandy soils. Like most brooms, it has apparently leafless stems that in spring and summer are covered with golden-yellow flowers. In late summer, its pea-pod like seed capsules burst open, often with an audible pop, spreading seed from the parent plant. It makes a shrub about 1–3m tall, rarely to 4m. It is also the hardiest broom, tolerating temperatures down to about -25 °C.

The brooms belong to the subfamily Faboideae of the legume family Fabaceae, mainly in the three genera  Chamaecytisus, Cytisus and Genista, but also in five other small genera (see box, right). All genera in this group are from the tribe Genisteae (syn. Cytiseae). These genera are all closely related and share similar characteristics of dense, slender green stems and very small leaves, adaptations to dry growing conditions. Most of the species have yellow flowers, but a few have white, orange, red, pink or purple flowers.

Folklore
A traditional rhyme from Sussex says: "Sweep the house with blossed broom in May/sweep the head of the household away." Despite this, it was also common to include a decorated bundle of broom at weddings. Ashes of broom were used to treat dropsy, while its strong smell was said to be able to tame wild horses and dogs.

Broom

A broom is a cleaning tool. It consists of stiff fibres attached to, and roughly parallel to, a cylindrical handle, the broomstick.  In the context of witchcraft, "broomstick" is likely to refer to the broom as a whole. A smaller whisk broom or brush is sometimes called a duster.

History of broom design

Brooms have changed very much in their construction, since they developed from ad-hoc use of branches and bundles of several natural fibres. Originally, all brooms were round, a shape that is easy to construct but inefficient for actually sweeping. Brooms could be attached to a handle, either short for a whisk broom, or long for a broom used to sweep the floor or fireplace. The word for the tool was originally besom, broom simply being the material of which it was normally made. The fibres used in modern brooms are from broom corn. They are long, straight, durable, and bound together  in the plant. The newest major change is the flat broom, invented by the Shakers in the 1800s, which has far more width for pushing dirt and nearly all brooms produced today are flat brooms.

Brooms and witchcraft

Brooms have long been connected with witchcraft, almost universally portrayed as medieval-style round brooms and associated with female witches. Despite the association with women, in 1453, the first known case of claiming to have flown on a broomstick is recorded, confessed by the male witch Guillaume Edelin.

In Literature and Poetry

In the Bible, Luke 15:8 "The Parable of the Lost Coin", the broom is used as a symbol for women's work.  "Or suppose a woman has ten silver coins and loses one.  Does she not light a lamp, sweep the house and search carefully until she finds it?"

In many works of fiction, broomsticks are pictured as a means of air transport for witches. A broom is usually flown with the brush behind the rider.

The Harry Potter book series is distinctive in portraying magical flying brooms as used equally by both sexes, and especially prominently by Quidditch players as analogues of polo ponies.

Many toys and costume accessories have been made in the form of brooms.

Cleanliness

Cleanliness means that there is no dirt, no dust, no stains, no bad smells. The goals of cleanliness are health, beauty, no offensive odor and to avoid the spreading of dirt and contaminants to oneself and others. In the case of glass objects such as windows or windshields, the purpose can also be transparency. Washing is one way of achieving cleanliness, usually with water and often some kind of soap or detergent. 

Since the germ theory of disease, it has also now means no germs and other waste. In industry, certain processes need conditions of exceptional cleanliness which are achieved by working in cleanrooms.
A very new idea is that ‘dirt’ may play a useful role in our immune systems. It is estimated that washing hands with soap and water could reduce diarrheal disease-associated deaths by up to 50%. A large percentage of foodborne disease outbreaks are spread by contaminated hands. Appropriate hand washing practices can reduce the risk of foodborne illness and other infections.

Washing is one way of cleaning, with water and often some kind of soap or detergent.  Washing is an essential part of good hygiene and health.

Soaps and detergents help to spread the oils and dirt particles through the water, so they can be washed away. The spreading of oil through water is called emulsification. 

People usually wash themselves periodically.

The Wash

The Wash is the square-mouthed estuary on the northwest margin of East Anglia on the east coast of England, "where Norfolk meets Lincolnshire". It is among the largest estuaries in the United Kingdom. It is listed as a Ramsar site as being an important wetland area.

Geography
The Wash looks on the map like a large bite out of the coastline of eastern England.  It separates the curved coast of East Anglia from Lincolnshire. It is formed by a large bay with three roughly straight sides meeting at right angles, each about 25 kilometres (15 miles) in length. All the eastern coast of the Wash is in Norfolk, and goes from Hunstanton in the north to the mouth of the River Great Ouse at King's Lynn in the south. The coast on the opposite side goes from Gibraltar Point to the mouth of the River Welland and is all in Lincolnshire. The southern coast goes roughly northwest-southeast, joining these two river mouths.  In the middle is the mouth of a third river, the River Nene.

Historical story
The most famous thing that people remember about the Wash is that "King John lost his crown in the Wash".  This is because, according to reports from the time, King John travelled from Spalding in Lincolnshire to Bishop's Lynn, in Norfolk in the year 1216.  He became ill and decided to go back.  While he took the longer route through Wisbech, he sent his luggage, including his crown jewels, along the seashore and across the mouth of the Wellstream where the water was not deep. This route was only safe when the tide was low.  The horse-drawn wagons moved too slowly for the incoming tide, and many were lost. The whole area at the time was an extensive wetland known as The Fens, which was later drained. It is close to sea level.

Thar Desert

The Thar Desert (, ), also known as the Big Indian Desert, is a desert. About 85 per cent is in western Republic of India and the rest in southeastern Pakistan.

It is mostly in the Indian state of Rajasthan. It extends into the southern portion of Haryana and Punjab states and into northern Gujarat state. In Pakistan, the desert covers eastern Sindh province and the southeastern portion of Pakistan's Punjab province. In Pakistan's Punjab province it is known as the Cholistan desert. Tharparkar District of province Sindh Pakistan is also a part of Thar desert. The Thar Desert is bounded on the northwest by the Sutlej River, on the east by the Aravalli Range, on the south by the salt marsh known as the Rann of Kachchh (parts of which are sometimes included in the Thar), and on the west by the Indus River.
 
Its boundary to the large thorny steppe to the north is not well defined. Depending on what areas are included or excluded, the nominal size of the Thar can vary.

Distribution

Distribution is the action of sharing something out among a number of recipients.

The word distribution has several usages:

Mathematics
In mathematics a distribution is a generalization of a function to be able to model certain systems, inspired by physics, see distribution (mathematics).

Probability theory and statistics
In Probability theory, it refers to the way a certain number of samples can be assigned to different categories, see Frequency distribution.
In Statistics, it refers to the probability that a random variable has a certain value, or falls inside a given interval, see Probability distribution. This is the theoretical counterpart behind frequency distributions.

Economics
In Economics, it talks about getting a product from the producer to the client. See distribution (economics).
This incudes things like movies and video games

Computer science
In Computer science, it may refer to the practice of allocating a number of tasks to different machines, scattered over a network. See distributed computing.

Computing
With Software, a distribution is something that puts different applications in the same package. See Linux distribution for an example.

Biology 
The study of the distribution of living things on the Earth is called biogeography.

Power system
 In power system, the process of delivering electricity to customer is called Electric power distribution.

Distributed computing

Distributed computing is a word from computer science, about using many computers to solve a big problem. One way to solve a big problem is to use a very fast computer called a supercomputer. Supercomputers are very expensive, and many scientists can not buy them. A cheaper way to solve a big problem is to split it into smaller problems, when possible. These smaller problems can then be solved by different computers (or processors), which talk to each other over a computer network. Because many computers work together, this makes them as powerful as a supercomputer. One example where distributed computing is used is the Great Internet Mersenne Prime Search.

Thymus

The thymus is a specialized lymphoid organ of the immune system. The thymus is in front of the heart and behind the sternum.

In the thymus, T cells or T lymphocytes mature. T cells are critical to the adaptive immune system, where the body adapts specifically to foreign invaders. 

The thymus is where T cells develop from hematopoietic (blood-forming) cells. In addition, this is where the T cells get tolerant to cells of the body.  

The thymus is largest and most active during the newborn and pre-adolescent periods.  By the early teens, the thymus begins to slow down. However, it continues to make lymphocytes throughout adult life.

Frequency distribution

In statistics, a frequency distribution is a list of the values that a variable takes in a sample. It is usually a list, ordered by quantity. It will show the number of times each value appears. For example, if 100 people rate a five-point Likert scale assessing their agreement with a statement on a scale on which 1 denotes strong agreement and 5 strong disagreement, the frequency distribution of their responses might look like:

This simple table has two drawbacks. When a variable can take continuous values instead of discrete values or when the number of possible values is too large, the table construction is difficult, if it is not impossible. A slightly different scheme based on the range of values is used in such cases. For example, if we consider the heights of the students in a class, the frequency table might look like below.

Applications 
Managing and operating on frequency tabulated data is much simpler than operation on raw data. There are simple algorithms to calculate median, mean (statistics), standard deviation etc. from these tables.

Statistical hypothesis testing is based on the assessment of differences and similarities between frequency distributions. This assessment involves measures of central tendency or averages, such as the mean and median, and measures of variability or statistical dispersion, such as the standard deviation or variance.

A frequency distribution is said to be skewed when its mean and median are different. The kurtosis of a frequency distribution is the concentration of scores at the mean, or how peaked the distribution appears if depicted graphically—for example, in a histogram. If the distribution is more peaked than the normal distribution it is said to be leptokurtic; if less peaked it is said to be platykurtic.

Frequency distributions are also used in frequency analysis to crack codes and refer to the relative frequency of letters in different languages.

Promenade concert

This article is about concerts in the parks in London in the 18th and 19th centuries. For the Promenade Concerts in the Royal Albert Hall see BBC Proms.

The word Promenade Concert today usually refers to one of the concerts in the series started by Henry Wood in 1895, known today as the BBC Proms.  However, before these concerts started there had for many years been promenade concerts in the parks of London. These concerts took place in the leisure gardens (parks) where people could walk about while listening to the music (French se promener = to walk).

People had to pay to go into the leisure gardens.  There were lots of entertainments there, e.g. fireworks, dancing, acrobatics and music.  The music was played by orchestras. Sometimes these orchestras played in bandstands, sometimes in proper buildings.

Vauxhall Gardens and Ranelagh Gardens were the most famous of these gardens.  The composer George Frideric Handel had his music played there in the 18th century. The gardens were very fashionable until the 19th century.  Aristocratic people, royalty and ordinary people all mixed there.  Handel's Music for the Royal Fireworks was performed in Vauxhall Gardens to celebrate the Treaty of Aix-la-Chapelle.  The composer Dr Thomas Arne was appointed composer of Vauxhall Gardens in 1745.  It was here that many of his songs became popular, including Rule Britannia''.  Wolfgang Amadeus Mozart and Joseph Haydn performed in Ranelagh Gardens on their visits to London.  
 
In the 19th century concerts of classical music became very popular.  The conductor Louis Antoine Jullien conducted many concerts.  His orchestra were even joined by the bands of the Royal Artillery or drummers from the French National Guard.  Concerts were also given in Crystal Palace, the huge glass building which was built for the Great Exhibition in 1851.

Many English composers had their music played in these parks.  The music was often long songs (ballads), or drinking songs.  Sometimes choirs sang choruses from oratorios by Handel.  Later in the 19th century the programmes included more music by famous composers such as Brahms, Liszt, Mendelssohn, Schubert, Schumann, Smetana and Wagner.

In 1895 Henry Wood started his series of promenade concerts.  He wanted to educate audiences so that they liked good music.  This series of concerts continues today in the Royal Albert Hall as the BBC Proms.
