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&nbsp;°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.

Peter, Paul and Mary

**Peter, Paul and Mary** were an American folk music group, most famous during the 1960s. The members are Peter Yarrow, Paul (Noel) Stookey and Mary Travers.

Their songs include "If I Had a Hammer" (also called "The Hammer Song"), "Puff, the Magic Dragon", "Leavin' On a Jet Plane" written by John Denver, and "Blowin' in the Wind", written by Bob Dylan. They recorded other Dylan songs, helping his early career. They made records, toured to perform, and appeared on television shows, including *The Smothers Brothers Comedy Hour*.

Peter, Paul and Mary disbanded in 1970, but reunited later, made tours and recorded new music.

Mary Travers died on September 16, 2009, after chemotherapy treatments for leukemia.

On January 7th, 2025, Yarrow died at age 86.

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.
## Types
* **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, involving a lot of risks. *Venture* can also be a verb, e.g. "They ventured out into the storm."
Washing

**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.

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. It is estimated that washing hands with soap and water could reduce diarrheal disease-associated deaths by up to 50%.

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
 (1899)]]
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.

satellite image of the **Thar Desert**. The image also shows the international border between India and Pakistan. The desert is at the center left of the image; the Indus River and its tributaries are to the left side of the desert, and the dark green line at the bottom center of the image is the Aravalli Range.]]

The **Thar Desert** (, ), also known as the **Great Indian Desert**, is a big desert in western parts of India and eastern parts of 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.The Thar Desert, also known as the Great Indian Desert, is an arid region in the north-western part of the Indian subcontinent that covers an area of 200,000 km2 (77,000 sq mi) in India and Pakistan. It is the world's 20th-largest desert, and the world's 9th-largest hot subtropical desert.
 
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.

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 breastbone.

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.
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.

Simulation

might look like.]]
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.

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.

The Wash

, in Norfolk, just south of Hunstanton]]

**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.http://www.jncc.gov.uk/pdf/RIS/UK11072.pdf 

## Geography
The Wash looks on the map like a large bite out of the coastline in 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 . It is close to sea level.

Frequency distribution

of Angola, for the year 2005.]]
 for the year 2005.]]
In statistics, a **frequency distribution** is a list of the values that a variable takes in a sample. It shows the number of times each value appears. 

For example, imagine that 100 people are asked whether they agree with a statement, and have to give an answer on a scale from 1 to 5, where 1 means they strongly agree and 5 means they strongly disagree. The frequency distribution of their responses might look like this:

A simple table like this might not work well in some cases. For example, if a variable can take any value within a range (for example, a measurement like height), or if the number of possible values is too large, making a simple table would be difficult or even impossible. In this case, we could instead use ranges of values. For example, the frequency table for the heights of the students in a class might look like the table below.

## Applications 
It can be simpler to work with a frequency distribution of data instead of the raw data. There are simple algorithms that can calculate median, mean (statistics) and standard deviation using 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.
