Humpback whale

A humpback whale (Megaptera novaeangliae) is a large baleen whale with long flippers and a knobbly head. They can be found in every ocean.

They can grow to 15–16 m (49–52 ft) long and weigh up to 40 metric tons.

Life history
Humpback whales can live up to 45 years.  They migrate between the places they feed in the winter and the places they give birth in the summer. They usually live alone.

Feeding 

Humpback whales eat krill and small fish, for example herring, capelin, and sand lance. They scoop up their food in their large mouths. Sometimes they round up their prey by swimming in tight circles and blowing curtains of bubbles around them. They often hunt in small groups, called pods.

Whale song 
The male whale is known to sing for up to 22 hours at a time. Because whales do not have vocal cords, they make songs by forcing air through their nasal passages. Every male has a different song. We don't yet know why they sing, it might be to call a female or scare away other males. The songs are made up of a pattern of low notes repeated over a period of hours or days. The whales slowly change their songs over a period of years.

Other sounds 

Both the male and female humpback whales make other sounds, such as moans and grunts, to communicate with each other.

Tap (valve)

A tap, faucet, or spigot is something that a liquid or gas comes out of. Taps usually have a handle that can be turned to start or stop the liquid coming out.

Many taps give water and are used in homes. They are found in kitchens and bathrooms.

Water that comes out of a tap is called tap water. At many restaurants, a person can ask for tap water instead of bottled water.

Competition

A competition or contest is an event where people get together to see who is the best at something.  Someone who takes part in a competition ("enters for a competition") is called a competitor.  The competitors compete against one another.  The person who wins may get a prize.  The prize might be a trophy or money.

Competitions can be for lots of different things, for example, sport, writing, music, dancing, science, or chess.

Some competitions need a referee.  The referee will make sure that the game is played fairly and that the competitors obey the rules.  In events like music competitions there will often be an adjudicator who will decide which person they think is the best.

Forms
In nature, animals compete with one another for the best food, the best nesting places, etc. According to Charles Darwin, the competition in nature results in evolution.
In business, firms that make the same things or offer the same services are in competition with one another (see market forms).

The adjective of 'competition' is competitive.
If persons are "competitive" it means that they like trying to compete with other people.
Businesses often say that they sell things at "competitive prices".  This means that their prices are lower than those of other businesses which sell similar things.

Examples of competitions
There are a lot of different kinds of competitions, for example:
 Eating competitions, where people try to eat the most food
 Running competitions, where people see who is the first to run from one place to another
 Sport competitions, where sports teams try to beat each other to win a trophy
 Singing competitions, where someone decides which person sang the best

SimCity

SimCity is a computer game where the player has to build a city. They can do whatever they want to their city. It can be built from the ground up or it can be destroyed by a hurricane or a UFO.

History
Sim City was made by game maker Will Wright and first released by the company Maxis. They are now owned by Electronic Arts. The game was first officially released in 1989.

It was very popular because the game had no end. A player could not win or lose. This was the start of all simulation games.

Gameplay
At the start, the player has to build power plants. Power plants make power so the city can have electricity. By building power lines, power is connected to the different areas of the city. Water needs to be pumped in from a river using pipes to connect them to the city.

Smaller areas are marked out. These are made either residential, commercial, or industrial zones. Zones are the only places where buildings can develop. Every city needs the right amount of each zone otherwise the city will not grow.

Roads, schools and hospitals must all be built for the city to get better. Parks and libraries make more people want to move to the city. Railways and highways provide ways to connect to other neighborhoods.

Sequels
After the first game, many more were created. These were made up of three games, with spin-offs and expansion packs. These were:
 SimCity 2000
 SimCity 3000
 SimCity 3000 Unlimited
 SimCity 3000 UK Edition

Doorstop

A doorstop (or door stop or doorstopper) is a tool.

There are two types. One holds a door open (or stops it from closing), and the other stops the door from hitting a wall.

Doorstops that keep the door from hitting a wall can be put on the door, or on the wall, or on the floor in front of the wall.

Doorstops that are used to keep a door open come in two varieties:
Attached to the door they are supposed to stop
Wedges that can be put under the door they should stop, or anything heavy put in front of the door

Digital rights management

Digital rights management (DRM) is a way to make it difficult to copy music, movies, and computer programs. It is used to make people follow copyright laws. It works by using computer technologies.

Many companies use DRM to protect their properties from copyright infringement, such as Sony, Microsoft and the BBC. Other companies also use DRM.

Some people do not like digital rights management. They think that DRM makes copying harder than copyright laws allow. The Free Software Foundation suggested that 'digital restrictions management' is a better name.

People can break DRM. If someone breaks a DRM technology then copying is possible. All common DRM technologies have been broken. Making a DRM technology that can not be broken is very hard. Some people say that all DRM technologies can be broken. In the United States it is illegal to break a DRM.

DRM is a way for companies to keep their profits while sharing their content online. A good example of this is BBC iPlayer. They do this by keeping their content online for a certain amount of time.

Cement

Cement is a material that hardens and sticks to other materials to hold them together. Portland cement is a common kind, and made from quicklime (heated limestone) and clay. Cement is used to make concrete and mortar. Cement is widely used for plastering and rendering. Plastering is done for the inner walls, and cement rendering is done for the exterior walls. Cement rendering is also used to clad brickwork on either exterior, interior, or boundary walls. This keeps brickwork protected from rain and water.

Joseph Aspdin developed Portland cement in the 19th century. He heated ground limestone and clay mix and then pulverized the mixture into fine powder. In 1824 he also obtained a patent for his creation. Portland cement is suitable for wet climates and can be used underwater.

The global cement market is estimated to be around $340 billion. China is the top cement producer, followed by India and the USA. The rising population is driving the cement demand. Countries in Asia, the Middle East, and Africa are improving their infrastructure which is resulting in the growth of the global cement industry.

Brown algae

Brown algae are a large group of multicellular algae. All the brown algae are multicellular. Most brown algae have fucoxanthin, a chemical that gives them a brown color. They include many seaweeds in colder waters of the Northern Hemisphere. Most brown algae live in marine environments, where they play an important role both as food and as a potential habitat.

There are 2000 species of brown algae. Most species live in the ocean. They are important as food and as homes for many animals and marine life. Some brown algae are gathered by humans for food. The giant kelp Macrocystis is a brown alga that forms underwater forests, and it may grow to 60 meters. The Sargasso Sea gets its name from the Sargassum seaweed that floats on the surface. Many brown algae grow on rocks at the seashore.

Brown algae are unique among heterokonts in developing into multicellular forms with differentiated tissues. But they reproduce by means of flagellated spores and gametes that look like the cells of other heterokonts. Genetic studies show their closest relatives to be the yellow-green algae (Xanthophyceae).

Classification
This is a list of the orders in the class Phaeophyceae:

Bacillus

Bacillus is a genus of rod shaped bacteria. They are Gram-positive, meaning they have an extra outside cell layer.

Bacilli are partly or wholly aerobic. They do aerobic respiration. They are every where in nature. Bacillus includes both free-living (non-parasitic) and parasitic pathogenic species.

Under stressful conditions, they produce endospores. These are not true spores, but like survival pods they can stay in a dormant state for long periods.

Some species of Bacillus are worth noting:

Bacillus anthracis, which causes Anthrax.
Bacillus subtilis is considered an model organism. It is often used in genetic engineering.
Bacillus cereus which is responsible for a form of food poisoning.
Bacillus thuringensis which is used in pest control. It produces a toxin which can kill some moths, and certain butterflies.

Individual

Individual can be an adjective or a noun.

As an adjective, a living thing that is individual is not in a group (by him/her/itself). An object that is individual is for only one person or thing (not shared by a group). Something that is individual can also be different from anyone else (unique).

Some students learn better with tutors because they get individual attention.
He has a very individual taste in music.

As a noun, an individual is only one person or thing, not a group. An individual can also mean someone who is different from anyone else (one a kind).

Crown-of-thorns starfish

The crown-of-thorns starfish (Acanthaster planci) is a type of sea star. Usually, they have orange-red to purplish skin, with yellow or pink spikes on their skin. The crown-of-thorns is also one of the largest starfish in the world, as it has a diameter of up to 3 feet. The crown-of-thorns lives in the warmer areas of the Pacific Ocean, Indian Ocean, and Red Sea.

It only feeds on coral polyps, and usually at night. The crown-of-thorns climbs over its prey, releases digestive enzymes to break down its food, and then absorbs the coral polyp, which has now turned into a liquid. What's left behind by the sea star is the leftover coral skeleton.

They are usually of subdued colours, pale brown to grey-green, but they may be garish with bright warning colours in some parts of their wide range. These bright colours warn animals that may want to eat it that it is venomous.

Effect on coral reefs 
The crown-of-thorns is well known for its destructive habits of eating coral, especially on the Great Barrier Reef, which is a World Heritage Site. Usually, when there are not too many of them, these sea stars help maintain the coral reef by preventing the faster-growing coral from taking over the coral reef. However, when there are too many crown-of-thorns, they can devastate the reef.

Echinoderms
Brittle star

Brittle stars are Echinoderms of the Class Ophiuroidea. The adults are superficially like starfish, but they are a different group, with different larvae. Like other echinoderms, they do have a skeleton of calcareous plates, and radial symmetry. There are about 1500 different species. 

Usually they have 5 arms, which can grow long, up to 60 cm, in the largest species. The central disk of brittle stars can be three to eight inches in diameter. Unlike starfish, they live deeper in the ocean. Ophiuroids are known even from abyssal (>6000 m) depths.  However, brittle stars are also common members of reef communities, where they hide under rocks and even within other living organisms. Generally, brittle stars live below 500m of depth. 

There are two related groups of Ophiuroids: the Ophiurida (brittle stars) and the basket stars (Eurialida). Basket stars usually live in the deeper parts of the range. Brittle stars are mostly scavengers and detrivores, able to catch some small prey on occasion.

Description 
Many brittle stars are more fragile than starfish, which is how they got their name. When they are picked up, their arms may fall off. This might make the animal seem brittle, but they often do this as a defense to escape from predators.

Movement 

Brittle stars do not use their tube feet for movement, but instead use muscles in their long, thin arms to go around rocks. Ophiurids move quickly when disturbed, and are faster movers than starfish. In living ophiuroids the plates are linked by longitudinal muscles. Ophiurid arms only move horizontally. The way their plates interlock prevents the arms from moving in any other plane.p64 In contrast, basket star arms can move vertically. These movement patterns are distinct, and separate the groups.

Ophiuroids in general are mostly scavengers or detritivores. Small organic particles are moved into the mouth by the tube feet. Ophiuroids may also prey on small crustaceans or worms. Brittle stars will eat small suspended organisms if available. In large, crowded areas, brittle stars eat suspended matter from prevailing seafloor currents.

Basket stars 
Basket stars (Euryalids) are large brittle stars with many rays. Their arms branch, and can be moved in any direction. This distinguishes them from the Ophiurids. Basket stars may be capable of suspension feeding, using the mucus coating on their arms to trap plankton and bacteria. They extend one arm out and use the other four as anchors. The arms form so many branches that they are almost feathery on the ends. They get their name because when they stretch their rays out to catch plankton, they look like the bottom of a basket.

Basket stars can be large and heavy, the biggest Ophiuroids. The largest, Gorgonocephalus stimpsoni, weigh up to 5 kg (11 lbs) and has arms 70cms long, with a disk diameter of 14 cm.

Bishop

Bishop is a type of clergy in some Christian churches. The bishop is the leader of the Christians and the Christian priests in each diocese. The diocese which a bishop governs is called a bishopric. Episcopal is the adjective for bishops. A cathedral is the church building where the bishop has an episcopal throne. The cathedral is the main church of the diocese and the bishop's see. A bishop may be given the rank of archbishop in an archdiocese. 

Christian priests in some denominations must be made priests by bishops. In these denominations, bishops are above parish priests in the hierarchy of the church's organization. However, some Protestant denominations have no bishops or archbishops. The Presbyterianism is an example. The leader of the Church of Scotland is the Moderator. The General Assembly elects the Moderator of the Church of Scotland each year. Other Christian movements have neither bishops nor priests: Quakers are one example.

In the Catholic church, the Pope is chosen by all the cardinals from amongst their number. According to church law, this does not have to be the case: any male, unmarried, baptized Christian who is judged fit for the office can become pope. However, the last pope who was not a bishop was Urban VI (elected in 1378).

The pope is also 'the Bishop of Rome'.  In fact he rules an independent state within Rome, called the Vatican.  All Roman Catholic bishops answer to the pope (or to patriarchs in some orthodox churches).  In the Anglican church, bishops are governed by Archbishops.

Usually a bishop can be identified by a special hat, called a mitre.

Tray

A tray is a shallow container designed for carrying things.

Trays are flat, but with raised edges to stop things from sliding off of them. They are often rectangular, and may or may not have handles with which to carry them.

A butler's tray has a deeper surround, handles on the short sides (usually cut into the surround) so that it can be easily carried, and folding legs. It is used to carry drinks, and can be used as a side table.

Orkney Islands

The Orkney Islands (often also called only Orkney)  is an archipelago in the Northern Isles of Scotland, United Kingdom. It is about 16 kilometres north of Caithness. 20 of the about 70 islands have people living on them.  The administrative centre is Kirkwall (with about 8000 people living there). The next largest settlements are Stromness (2000 people) and St. Margaret's Hope (with about 550 people).

In addition to the mainland, most of the islands are in two groups, the North and South Isles. All of them are made of sandstone. The climate is mild and the soil is fertile. Most of the land is farmed and agriculture is the main source of income for the economy. There are many birds and fish.

In 2023 there were proposals that the islands could change their status in the UK, to be more like the Isle of Man or even become a self-governing territory of Norway.

Transportation 
Ferry services go much of the time to Lerwick (in Shetland). Most islands have air strips (for airplanes). This includes the shortest known flight service in the world, between Westray and Papa Westray. Official flight time is 2 minutes. If the wind goes in the right direction, the flight can take just over a minute.

Methodism

Methodism, or the Methodist movement, is a group of Protestant denominations. The movement started in Britain in the 18th century and spread to the United States and the British Empire. Originally it was popular with workers, poor farmers, and slaves. Mr. John Wesley started Methodism. He was a priest of the Church of England. His brother Charles Wesley was a famous writer of Church music. 

There are many Christians that trace their roots to the Wesley brothers. Many Churches have the word Methodist as part of their name, but others do not. Some of the churches which came from the Wesley movement are Nazarenes, Churches of God, Pentecostals, Holiness, and the Salvation Army. Many of these groups do good things to help people in addition to telling them about salvation from their sins. They start hospitals and schools and work with homeless and poor people. 

Methodists differ from other denominations in some beliefs. They are usually Arminian in their teachings about salvation. This means that they teach that anyone can choose to believe in Jesus. This is because of God's grace in making Himself known to all.https://dukespace.lib.duke.edu/dspace/bitstream/handle/10161/7972/Introducing_Wesleyan_Tradition.pdf This is also called "free will" teaching. Methodists also tend to accept those whose beliefs are not exactly the same as theirs on less important things. The most important Methodist beliefs are listed in the 25 Articles of Religion.

Vas deferens

The vas deferens (or ductus deferens)   is a duct in a man’s body.  It is also present in other male vertebrates. Its function is to carry sperm away from the testes, towards the penis.

There are two of these ducts, which are tubes surrounded by smooth muscle.  They connect the left and right epididymis to the ejaculatory ducts in order to move sperm. Each tube is about 30 centimeters long. During ejaculation the smooth muscle in the wall of the vas deferens contracts. That pushes the sperm toward the penis. The sperm go from the vas deferens into the urethra. Other male sex glands push out at the same time.

Vasectomy 
There is a surgery called vasectomy that is a method of contraception. The two vasa deferentia (Latin plural) are cut and sealed, so the sperm cannot get out of the body. This is usually permanent, but in some cases, it can be reversed.  Sometimes instead of cutting the vas deferentia, the surgeon puts something to block the sperm instead of cutting them.

Che Guevara

Ernesto "Che" Guevara, commonly known as el Che or Che  (June 14, 1928 - October 9, 1967) was an Argentine Marxist, revolutionary, physician, author, guerrilla, diplomat, and military theorist. He is popular with socialists. In addition to that he was a writer and some of his articles and speeches were even published.

Time magazine said he was one of the most influential people of the 20th century. Guerrillero Heroico, a picture of him, is called "the most famous photograph in the world."

Biography 
Che Guevara was born in Rosario, Argentina in 1928. He studied at the University of Buenos Aires. He wanted to be a doctor. During his holidays, he traveled. He saw how poor some people were. He thought that revolution could fix it.

After college, he went to Mexico. He met Fidel Castro there in 1954. Castro was planning a rebellion in Cuba. Guevara joined Castro. He fought with Castro in Cuba. In 1959, Fidel won and became president of Cuba. Fidel and Guevara declared Cuba a communist country. Guevara was made head of Cuba's bank. He later became Minister of Industry. In 1965, Guevara helped to start other revolutions. They were in Congo-Kinshasa and Bolivia. In 1967, he was captured and executed by Bolivian soldiers. His body was not found until 1997. His nickname among friends was "Chegi Vara".

Che in popular culture 

People have different opinions on Che Guevara. Some see him as a good leader. In addition to that he was an excellent writer and some of his articles and speeches were even published. Others see him as a bad man who wanted to hurt people. A black and white image of Guevara's face is one of the most merchandized images. It can be found on many items. They include t-shirts, hats, posters, and other items. The image was based on a photograph by Alberto Korda Díaz. Díaz was a Cuban photographer. It was taken in 1960.

Guevara is still an important person. He is seen as an example of youthful rebellion.

A movie, The Motorcycle Diaries, is about Che. It describes a trip that he took through South America. The trip took place in the 1950s. The movie was directed by Walter Salles. It was produced by Robert Redford.

Whisker

A whisker is a long, thick hair around the mouth of some animals, mostly mammals such as cats and mice, that the animal uses to feel its surroundings. Some animals, such as cats, also have whiskers above their eyes and on the backs of their legs. Unlike other hair, whiskers should never be cut or trimmed, as this can confuse the animal.

Whiskers can also mean a beard or mustache.

Magma

Magma is the melted rock under the ground. The liquid rock may have solid bits mixed in with it, and volcanic gas.  

There are different types of magma. One is called felsic magma. Felsic magma is thick and has silica minerals. It mostly makes light-coloured rocks. Another type is called mafic magma, which is runny and has less silica. It usually makes dark-coloured rocks. Magmas can be intermediate between both types. 

Magma may become solid  by cooling slowly below the surface. This makes "plutonic" rocks such as granite. When magma comes out from the ground in a volcano it is called lava. Lava cools quickly, and forms other kinds of rock such as basalt. 

Magma is produced by melting of the Earth's mantle or the crust. It happens at tectonic settings, such as subduction zones, continental rift zones, mid-ocean ridges and hotspots. 

Melted material from the mantle and crust moves up through the crust and collects  in magma chambers. 

When they come up through the crust, magmas may feed a volcano and come out  as lava. But they may solidify underground to form an intrusion (magma which cools and becomes solid). Intrusions eventually cool down and become igneous dikes or  sills. 

The study of magma is usually done in lava flows. However, magma was found under the ground three times in geothermal drilling projects—twice in Iceland and once in Hawaii.

Glue

Glue is a sticky material (usually a liquid) that can stick two or more things together. Glue can be made from plant or animal parts, or it can be made from oil-based chemicals. 

The first glues may have been natural liquids that come out of trees when they are cut. Later, people learned to make glue by boiling animal feet, cartilage or bones. Some very strong glues were first made from fish bones, rubber or milk.

A simple glue can be made at home by mixing wheat, flour and water. This glue will stick pieces of paper together.
Many kinds of art can be made using glue. A collage is a work of art made by using glue to stick coloured things onto paper. 

Some glues can be used to keep water out of boats, buildings or vehicles. In this case, the glue may be called caulk. Some man-made materials, including wood-like materials, are made using glues to bind together small pieces of material or powders. 

While many glues are safe, certain kinds of glue contain strong-smelling chemicals. Some people sniff these glues to get high. Sometimes people breathe in the vapors by mistake. This is a very bad idea because these chemicals are often poisons and may cause brain damage or illness.    

Glue can also be made from rice or rice flour.

Yenisei

The Yenisei (Енисе́й) is a river in Siberia. It belongs to the greatest river system that flows into the Arctic Ocean. The Yenisei is the fifth-longest river in the world. It is a little shorter than the Mississippi River, but with 1.5 times the flow. It comes from Mongolia and follows a northern course to the Kara Sea. The river drains a large part of central Siberia. The longest stream following the Yenisei-Angara-Selenga-Ider is about 5539 km long. Its watershed, which includes the world's largest (by volume) lake, Lake Baikal, holds more water than any other river system.

The upper parts of the system have rapids and flooding, and pass through areas where very few people live. The middle section is controlled by a series of large hydroelectric dams. The dams were built to supply a major Russian primary industry. Partly built by gulag labor in Soviet times, industrial contamination is a big problem in the area. The area is very hard for the police to watch. Moving on through sparsely populated taiga, the Yenisei grows with many tributaries and finally reaches the Kara Sea in desolate tundra where it is covered with ice for more than half the year. As with other Siberian rivers, the flow has increased lately. People think this is because of global warming. A concern was also raised that a change in the salt in the Arctic may have a global impact on ocean currents.

Siberia

Bartolomeu Dias

Bartolomeu Dias(or Bartholomew Dias, 1450 - May 29, 1500) was a Portuguese explorer who was the first European to sail past the Cape of Good Hope now Cape Town.

Voyage to Africa 
In 1487, King John II of Portugal asked  Dias to find a new route for the spice trade and to find a legendary Christian king named Prester John in the east. In 1488 Bartholomew and his sailors sailed along the western coast of Africa. They got caught in a storm and landed at a cape in southern Africa and they could not sail beyond that point. They named it "Cape of Storms" and later returned to Portugal. The king of Portugal considered it as a victory gained by the Portuguese adventurers and named it as "Cape of Good Hope".  Because Prester John did not really exist, they did not find his country but the route from the Atlantic Ocean to the Indian Ocean leading to Asia turned out to be valuable.

Death and legacy 
Commanding a ship in Pedro Álvares Cabral's later expedition to Brazil and India, he died at sea in 1500 during a storm.  There was a statue made for him later in Cape Town, South Africa.

CD-R

A CD-R (also called Compact Disc Recordable) is a compact disc that can be recorded once. When people record a compact disc, they put either music or data on it, or sometimes both, which is called an enhanced CD.

A compact disc that can be recorded multiple times (and erased) is the CD-RW.

When you put data onto a CD, it is called burning a disc. A laser "burns" pits into a dye layer on the disc, making them transparent. These transparent pits can later be read back by the CD drive or audio CD player as data or music.

The first CD-Rs from the early 1990s held 63 minutes of audio. In the mid-1990s, 74-minute discs became common. Most CD-Rs made from 2000 onward hold 80 minutes, or 700 MB of data. 90 and 99-minute CD-Rs are available since 2000, although they are non-standard and many players and recorders do not support them.

There are three types of dye used in CD-R discs. The most common is phthalocyanine, and it is usually light green. CMC Pro (formerly Taiyo Yuden) uses cyanine dye. It is usually teal or dark green. Verbatim uses phthalocyanine dye on some discs, and AZO dye on others. AZO dye is usually dark blue or blue-ish silver. The metal layer on the disc is usually made of silver. Archival discs and some professional audio discs use a gold top layer. Verbatim UltraLife discs have a silver main layer, and a gold upper protective layer, providing the reflectivity of silver and the chemical stability of gold. Early cyanine discs could decay and become unplayable within a few years. Recent cyanine discs have preservatives added to the dye to prevent this from happening. AZO and phthalocyanine dyes do not need preservatives and do not decay easily. Phthalocyanine is the most stable and longest-lasting dye, but it requires a more precisely calibrated laser than AZO or cyanine to get a good, error-free burn. A recording laser with too much or too little power will produce a poor recording on phthalocyanine dye.

There are two types of blank CD-R, "music" and "data". The only difference is that "music" discs have a bit set on the disc that indicates a royalty was paid to the music industry. Consumer-grade music recorders look for this bit and won't record to discs without it. This is done to meet the requirements of the Audio Home Recording Act and similar laws. Professional equipment (including rackmount audio CD recorders and all computer drives) is not affected and will record to either type of disc. The bit has no effect on playback once the disc has been recorded.
