title: Elizabeth II

text: On 8 September 2022, Buckingham Palace said that the Queen was under medical supervision at Balmoral after doctors said that they were concerned by her health. The statement read, "Following further evaluation this morning, the Queen's doctors are concerned for Her Majesty's health and have recommended she remain under medical supervision. The Queen remains comfortable and at Balmoral." The Queen's four children, along with Prince William, Prince Harry, and Camilla, Duchess of Cornwall, travelled to be with her. Her death was announced in the evening of the same day.


title: Elizabeth II

text: Her daughter Princess Anne registered the death certificate of Elizabeth II. It said she died at 8 September 2022 at 15:10 at Balmoral Castle. It also said she died of old age including osteoporosis.


title: Elizabeth II

text: In 1977, the Queen celebrated her Silver Jubilee. This jubilee marked the 25 anniversary of her coming to the throne. There was a royal procession in the golden State Coach. A service of thanksgiving was held at St. Paul's Cathedral. Millions of people watched on television. There were parties across the UK. Five commemorative stamps were printed in honour of the event. The Jubilee line of the London Underground opened in 1979, named after the anniversary.


title: Elizabeth II

text: In 2002, Elizabeth II celebrated Golden Jubilee. This jubilee marked the 50th anniversary of her coming to the throne. She toured the Commonwealth countries. There was a pop concert in the gardens of Buckingham Palace. A service of thanksgiving was held at St. Paul's Cathedral.


title: Elizabeth II

text: The Queen and Prince Philip celebrated their sixtieth (diamond) wedding anniversary on 19 November 2007, with a special service at Westminster Abbey. The night before, Prince Charles gave a private dinner party at Clarence House for 20 members of the Royal Family.


title: Elizabeth II

text: On the following day, 20 November, the Queen and Prince Philip went on a visit to Malta, where they had stayed from 1949 to 1951 after getting married. A Royal Navy ship, which was nearby, got its sailors to line up on deck to form a big number '60' for the couple.


title: Elizabeth II

text: In 2012, the Queen's 60 years as monarch were marked by Diamond Jubilee celebrations, including a grand pageant of boats on the Thames and a service of thanksgiving at St Paul's Cathedral.


title: Elizabeth II

text: In 2017, the Sapphire Jubilee marked the Queen's 65 years as monarch. She was the first British monarch to have a Sapphire Jubilee. Instead of large celebrations, as usual, the Queen spent the day in "quiet reflection" because the day was also the anniversary of her father's death. Commemorative stamps and coins were made in honour of the Jubilee, and a portrait of the Queen wearing sapphire jewellery was reissued.


title: Elizabeth II

text: Also in 2017, the Queen and Prince Philip celebrated their seventieth (Platinum) wedding anniversary. They held a private celebration at Windsor Castle. Westminster Abbey, where they were married, held a three-hour bell ceremony.


title: Elizabeth II

text: The Queen's Platinum Jubilee was held in February 2022, meaning she has been Queen for 70 years. She would have surpassed Louis XIV of France as the longest-reigning monarch of a sovereign state in world history if she remained Queen until 27 May 2024.


title: Elizabeth II

text: When someone is talking about the Queen, she is called "The Queen" or "Her Majesty". When someone was talking to her, she was called "Your Majesty". After the first time, the person talking to the Queen could say "Ma'am". It is pronounced "Marm". These are the titles that she had:


title: Elizabeth II

text: The Queen had several coats of arms. In the UK, they are known as the "Royal coat of arms of the United Kingdom". Every British monarch has used these arms since the reign of Queen Victoria. The coats of arms used in Scotland and Canada are different to the arms used in England and Wales.


title: World War I

text: World War I (WWI or WW1), also called the First World War, began on July 28, 1914 and lasted until November 11, 1918. It was a global war and lasted exactly 4 years, 3 months and 2 weeks. Most of the fighting was in continental Europe.


title: World War I

text: Soldiers from many countries took part, and it changed the colonial empires of the European powers. Before World War II began in 1939, World War I was called the Great War, or the World War. Other names are the Imperialist War and the Four years War. There were 135 countries that took part in World War I, and nearly 10 million people died while fighting.


title: World War I

text: Before the war, European countries had formed alliances to protect themselves. However, that made them divide themselves into two groups. When Archduke Franz Ferdinand of Austria was assassinated on June 28, 1914, Austria-Hungary blamed Serbia and declared war on it. Russia then declared war on Austria-Hungary, which set off a chain of events in which members from both groups of countries declared war on each other.


title: World War I

text: The two sides were the Allied Powers (mainly Russia, France, the British Empire and later the United States) and the Central Powers (mainly Germany, Austria-Hungary and the Ottoman Empire).


title: World War I

text: There was fighting in many different fronts (areas). The French and the British fought the Germans on the Western Front in France and Belgium. Germany had tried to defeat France quickly with the Schlieffen Plan but were stopped in the First Battle of the Marne. Most of the fighting on the western front was trench warfare. The Russians fought the Germans and Austro-Hungarians on the Eastern Front in Central and Eastern Europe. Fighting on the eastern front was not trench warfare as in the west, but mobile warfare. The other main areas of fighting were in the Middle East, in the Gallipoli region of the Ottoman Empire and between Italy and Austria-Hungary. Fighting also took place in Africa, China, at sea and in the air. World War I was the first major war in which tanks, airplanes and submarines (or U-boats) were important weapons.


title: World War I

text: In 1917, the Russian Revolution led to Russia leaving the war in March 1918. Also in 1917, the United States entered the war, but it took a year for most of its army to arrive. From the time of the Russian departure, before the American arrival, the Germans launched a huge attack in March 1918 to try to win the war, but it failed.


title: World War I

text: From August to November 1918, the Allied Powers won a large victory against the Germans during the Hundred Days Offensive. Austria-Hungary and the Ottoman Empire then agreed to stop fighting. The German government collapsed, and a new government was forced to agree to stop the fighting on November 11, 1918. Basically, the Germans ran out of men.


title: World War I

text: Also, the influenza pandemic of 1918 had a big influence. It killed many people in Europe: it lasted for three years, from January 1918 to December 1920. About 500 million people were infected across the world which then had a population of 1.80 billion people.


title: World War I

text: The war was ended by the signing of many different treaties, the most important being the Treaty of Versailles. It also led to the creation of the League of Nations, which was meant to prevent wars. People were shocked by the size of the war, how many people it killed and how much damage it caused. They hoped it would be "the war to end all wars". Instead it led to another, larger, world war 21 years later.


title: World War I

text: By 1914, trouble was on the rise in Europe, and many countries feared invasion from others. For example, Germany was becoming increasingly powerful, and the British Empire saw that as a threat. Countries formed alliances to protect themselves, but that divided them into two groups. Germany and Austria-Hungary had been allies since 1879 and formed the Triple Alliance with Italy in 1882. France and Russia became allies in 1894 and later formed the Triple Entente with Britain.


title: World War I

text: In 1908, Austria-Hungary had taken over Bosnia, a region next to Serbia. Some of those who lived in Bosnia were Serbs and wanted to be part of Serbia. The Black Hand was an organization that agreed with the idea and sent men to kill Archduke Franz Ferdinand of Austria while he was visiting Sarajevo, the capital of Bosnia. All of them failed to kill him with grenades while he passed through a large crowd. However, one of them, a Serbian student, Gavrilo Princip, shot him and his pregnant wife with a pistol.


title: World War I

text: Austria-Hungary blamed Serbia for the assassination. Germany supported Austria-Hungary and promised full support in case of war. Austria-Hungary sent the very harsh July Ultimatum to Serbia and threatened war unless Serbia agreed to all of its terms. Many historians think that Austria-Hungary already wanted a war with Serbia. Serbia agreed to most of the conditions, but Austria-Hungary still declared war on Serbia, which quickly led to a full-scale war. The countries had allies that entered the war in a matter of days.


title: World War I

text: Russia joined the war to help Serbia because both Serbs and Russians are Slavs. Russia began to assemble its army (mobilize), which caused Germany to began to mobilize its forces. Germany declared war on Russia in support of Austria-Hungary and began to carry out its plan to fight a war in Europe.


title: World War I

text: Germany is in the middle of Europe and so it had to worry about enemies to its east and west. Germany's plan was the quick defeat of France in the west before Russia was ready to fight, then Germany would move its armies to the east to face Russia. However, Germany could not quickly invade France directly because France had put so many forts on the border. That made Germany invade the neighboring country of Belgium to invade France through the undefended French-Belgian border.


title: World War I

text: Britain then joined the war and said that it was to protect Belgium. However, some historians think that even if Germany had stayed out of Belgium, the British would have still joined the war to help France.


title: World War I

text: Soon, most of Europe became involved. The Ottoman Empire (now Turkey) joined the war on the side of Germany and Austria-Hungary. It is not clear why the Ottomans entered the war, but they had become friendly to Germany. Italy had allied with Germany and Austria-Hungary but refused to help them since those countries had not been attacked first. Italy noted that Austria-Hungary had attacked Serbia first. Also, Italy had long disliked Austria-Hungary and wanted to take part of its land. It later joined the war for the Allies because they had promised land across the Adriatic Sea.


title: World War I

text: Germany was afraid that because Austria-Hungary had attacked Serbia, Russia would attack Austria-Hungary to help Serbia. That made Germany feel that it had to help Austria-Hungary by attacking Russia first.


title: World War I

text: The problem was that Russia was allied to France, and the Germans thought that the French might attack them to help Russia. That made Germany decide that it could win the war by quickly attacking France first. The Germans could mobilize first since they had a list of all men who had to join the army, where they had to go, and the times of every train that would carry them to where they had to go.


title: World War I

text: France was slower in doing the same thing. The Germans thought that if they attacked France first, they could knock it out of the war before Russia could attack them.


title: World War I

text: Russia had a large army, but Germany mistakenly thought that it would take six weeks to mobilize and a long time before they could attack the Central Powers. However, the Russian Army mobilized in ten days and drove deep into Austria-Hungary.


title: World War I

text: In the east, the Russians attacked the Germans. The Russians pushed back the Germans, but the Germans then defeated the Russians at the Battle of Tannenberg.


title: World War I

text: The United Kingdom quickly joined the war and said that it was to protect Belgian neutrality. Germany passed through Belgium to reach Paris before Russia could mobilize and open up a second front. On August 4, 1914, the British declared war against Germany in support of Belgium. The British Empire was larger than any other empire and ruled over a quarter of the world. If Germany won in France, it might take British and French colonies and become the most powerful and largest empire in the world.


title: World War I

text: Britain was also worried about Germany's growing military power. Germany was developing its large army into one of the most powerful in the world. The British Army was quite small, but the Royal Navy was the largest and the best in the world, which in the 19th century was enough to keep other naval powers from attacking Britain.


title: World War I

text: Germany was a land power, and Britain was a sea power. However, Germany was building a large navy, which was seen as a threat to Britain. Germany's generals had decided that the best way to defeat France was to go through Belgium using a plan called the "Schlieffen Plan" by German Army Chief of Staff Alfred Von Schlieffen. The Germans could then attack the French army at the north side and the south side at the same time. The German Army went into Belgium on August 4. The same day, the British declared war on Germany. The British had said in 1839 that they would not let Belgium be invaded, and they kept their promise.


title: World War I

text: When the Germans got to the Belgian city of Liège, the Belgians fought very hard to stop them from coming into the city. The Germans finally pushed the Belgians out of the city, but it had taken longer than the German generals had planned. The Germans then attacked the north side of the French army. The French and the British moved men up to fight the Germans because the Belgians had fought so long at Liège. However, the Germans pushed the French back at the frontiers, and the British held the Germans back at Mons, but they also fell back to join up with the retreating French Army until they were stopped at the river Marne. This was the First Battle of the Marne or "Miracle of the Marne".


title: World War I

text: The British government might have decided differently if anyone had foreseen how long the war would last and what a terrible price Britain would pay.


title: World War I

text: Most people thought that the war would be short. They thought the armies would move around quickly to attack each other and one would defeat the other without too many people getting killed. They thought the war would be about brave soldiers and did not understand how war had changed. Only a few people, such as Lord Kitchener said that the war would last long.


title: World War I

text: The Ottomans joined the war because they were secretly allied to Germany, and two Ottoman warships, manned by German Navy personnel, bombarded Russian towns.


title: World War I

text: Britain fought against the Ottomans only for supporting Germany and had no other problem with them. However, by fighting them in the Mesopotamia region in what is now Iraq, in the Arabian Peninsula and in other places, Britain defeated them with the help from the British Indian Army. After the war ended, Britain got some Ottoman areas and added them to the British Empire.


title: World War I

text: Greece went into the war because its leader supported the Allied cause. Greece and Serbia had become independent, but many Greeks still lived in lands that had once been Greek but were now Ottoman. Having recently won the Balkan Wars, the Greeks wanted especially to control other land to the north that was under Bulgarian and Ottoman rule and so they declared war. The Ottomans killed most of the Greek Army as they tried to regain parts of the Ottoman Empire. Another war started when the Greeks bombed a train. The Ottomans swept the Greeks back into their own territory. From then on, the Greeks never again declared war, but the Ottomans had one of the largest armies in the world.


title: World War I

text: Bulgaria, like Greece and Serbia, had been part of the Ottoman Empire but later became independent. Bulgaria claimed a lot of Ottoman land. The Serbians and the Greeks felt cheated because they felt that the land belonged to them and took back the land. That angered Bulgaria and led to it becoming an Ottoman ally. Bulgaria declared war on Serbia and Greece but lost the war.


title: World War I

text: Trench warfare killed many soldiers. New weapons, such as machine guns, and long-range artillery had an increased rate of fire that cut down huge numbers of soldiers during mass charges, a tactic left over from older warfare. The men on both sides took spades and dug holes because they did not want to be killed. The holes joined up into trenches until the lines of trenches went all the way from Switzerland to the North Sea. In front of the trenches was barbed wire to cut anyone who tried to climb over it and land mines to blow up anyone who tried to cross. Late in the war, poison gas also was an important weapon.


title: World War I

text: The new machine guns, artillery, trenches, and mines made it very difficult to attack. The generals had fought many wars without them and so they ordered their armies to attack in the old style of marching in rows, which allowed the enemy to shoot them down easily. At the 1916 Battle of the Somme, 60,000 British men died in a single day, one of the bloodiest days in the history of the British army. Late in the war, the British and French invented tanks and used them to attack entrenched Germans, but they could not make enough of them to make a big difference. The Germans invented special Sturmabteilung tactics to infiltrate enemy positions, but they also were too little, too late.


title: World War I

text: The British used whistles to communicate to other soldiers and so before they shelled the German trenches, they would sound the whistle. However, the Germans caught on to this tactic and so after the shelling, when the British soldiers came to finish off the German soldiers, the Germans were ready with their machine guns because they knew that the British were coming.


title: World War I

text: Airplanes were first used extensively in World War I. They were first used for reconnaissance, and pictures of enemy land were taken to help direct artillery. Generals, who are military leaders, were using airplanes as an important part of their attack plans at the end of the war. World War I showed that airplanes could be important war weapons.


title: World War I

text: Airplanes in World War I were made of wood and canvas, a type of rough cloth. They did not last long and could not fly very fast at the beginning of the war. They could only fly up to 116 kilometers per hour, or 72 miles per hour. At the end of the war, they could fly up to , much slower than modern planes. Guns were put on planes for the first time during the war. Pilots, people who fly the plane, used the guns to shoot enemy planes. One pilot used metal sheets to armor his airplane. Other pilots began using metal sheets too. Pilots also made their airplanes better with machine guns, guns that shoot bullets much faster. That made fighting harder and more dangerous between airplanes.


title: World War I

text: Pilots had to wear certain clothes when flying an airplane in World War I because they flew high, where the air is cold. The pilots' clothes kept them warm and protected them from the wind and cold. Pilots wore a leather coat to protect their bodies, a padded helmet and goggles, which are large glasses with special lenses, to protect their head and face. They wore a scarf around their neck to keep the wind from blowing against their neck when they turned their head.


title: World War I

text: The German leaders decided to use submarines, called U-boats, from the German word "Unterseeboot" (meaning "underwater boat"). The U-boats attacked passenger ships such as RMS Lusitania carrying civilians to the United Kingdom. They did not follow the laws of war because the British could easily destroy them otherwise. America was selling weapons to Germany's enemies but not to Germany and so was not neutral since the US had taken sides during the conflict. Many American and British noncombatants were killed by the submarines although they were not fighting.


title: World War I

text: Germany also wrote a secret telegram note to Mexico in code that suggest that both countries work together to attack the United States. This note is called the Zimmerman Telegram because it was sent by Arthur Zimmerman. It offered Mexico land in the Southwestern United States that the United States had taken in the Mexican-American War. British spies found out about the note and told the United States. The Americans became angry, and many decided that their country should enter the war against Germany. The Zimmermann Telegram and the sinking of American ships by German U-boats made the United States on April 6, 1917 declare war against Germany and join the Allies.


title: World War I

text: They made Russia fight both Germany and the Bolsheviks at the same time. That meant Russia wanted to end the war against Germany.


title: World War I

text: That made Russia want to pay many German marks to make stop the fighting between it and Germany so that it could focus on fighting the Bolsheviks.


title: World War I

text: In 1917, there was a revolution in Russia. Tsar Nicholas II had to give up power and a new government was established. At first, it was thought that Russia would fight harder now that he was gone. However, the Russians did not want to fight anymore because there was too little food, weapons or adequate roads to supply its army. The war had been putting burdens on the Russians, and many of them were poor and hungry. They began to hate their new government because it would not stop the war.


title: World War I

text: Another revolution happened in Russia in which the Mensheviks lost to the Bolsheviks (these were two rival groups of communists). The leader of the Bolsheviks was Vladimir Lenin (1870-1924), a communist who followed the ideas of Karl Marx. The new Bolshevik government asked the Germans for peace and signed the Treaty of Brest-Litovsk with the Central Powers in March 1918 at the city of Brest-Litovsk. Lenin later died in 1924 and was replaced by Joseph Stalin.


title: World War I

text: The Germans and Russians stopped fighting. Russia gave Germany land in Eastern Europe and the Baltic Sea, including the Baltics, Poland, Ukraine and Belarus. Also, Finland gained its independence by the treaty.


title: World War I

text: After the war, the Germans had to agree to the Treaty of Versailles, which stated that Germany had to pay approximately $31.5 billion in reparations and had to take full responsibility for the war.


title: World War I

text: Also, the countries of the world were to come together to make an international organization to stop future wars: the League of Nations. The United States Senate did not agree with the League even though it was the idea of United States president Woodrow Wilson. Although Wilson tried to tell the American people to agree to join the League, the United States never joined it.


title: Pornhub

text: Pornhub is a pornographic video sharing website and the largest pornography site on the Internet. Pornhub was launched in Montreal in 2007. Pornhub also has offices and servers in San Francisco, Houston, New Orleans and London.


title: Pornhub

text: The website allows visitors to watch pornographic videos from a number of categories, including professional and amateur pornography. Users can take advantage of several features, including sharing videos on social media websites and liking or disliking them. Users may also optionally register a free Pornhub account, which additionally allows them to post comments, download videos and add videos to their favourites, as well as upload videos themselves.


title: Pornhub

text: Since 2012, Pornhub has hosted several events and campaigns to raise awareness of certain issues or raise money, as well as to help promote its brand. In March 2010, Pornhub was bought by Manwin (now known as MindGeek), which also owns other pornographic websites.


title: Pornhub

text: On March 12, 2014, Pornhub was blocked in Russia because one actress looked too young, leading some viewers to think she was a minor.


title: Pornhub

text: On January 2017, Pornhub was blocked in the Philippines. Pornhub and similar pornography websites were blocked in order to comply with (follow) the Anti-Child Pornography Law.


title: Pornhub

text: Pornhub was blocked in September 2016 in Russia due to "spreading harmful information to children". On April 2017, it was unbanned, but it now asks users to specify their age. Now, Russian users must provide their cellphone numbers or passports to access Pornhub.


title: Pornhub

text: In October 2018, the Uttarakhand High Court re-banned Pornhub in India, enforced by blocks from internet providers of India. In order to get around the ban, Pornhub created a mirror website at Pornhub.net.


title: Marxism

text: These ideas come from the works of Karl Marx and Friedrich Engels and their most notable work is The Communist Manifesto. They have had a lot of influence in many countries. Marxism influenced other political views, such as social democracy and reformist socialism. Both believe that the ideas of Marx and Engels can be achieved through what Marx called 'bourgeois democracy'.


title: Marxism

text: People disagree a lot on how a Marxist society should be organized: "Marxist political economists differ over their definitions of capitalism, socialism and communism. These differences are so fundamental, the arguments among Marxist political economists have sometimes been as intense as their oppositions to capitalism".


title: Marxism

text: Marxism says that people in the world are organized into different groups, or classes, based on what they do for work.


title: Marxism

text: Most people are called "workers" because they work in factories, offices, or farms for money. They belong to the "working class" (or "proletariat"). These people do not own the places they work in or the materials they need for their work.


title: Marxism

text: Another group, who are not as big as the working class, are "capitalists" (or "bourgeoisie"). They own the factories, land, and buildings that the workers work in. They also own some of the tools the workers have to use. Marx calls capitalists the "Ruling Class" because they live off of the work of all the workers. He also says that the capitalists own the government, army, and courts.


title: Marxism

text: In Marxist views, capital is the "means of production" and money which the capitalist can invest in different places of business, so that they can "profit" or gain more capital.


title: Marxism

text: Most workers work for companies owned by either capitalists or "petit-bourgeois" (small-time exploiters). The capitalist pays the worker in exchange for the worker's time. The capitalist has bought a period of time from the worker, which the worker must then use to labor for the capitalist. According to Marxist thinking, this is the only way that a capitalist can create extra money from a commodity (a piece of merchandise). The capitalist exploits the worker's time as much as they can. The capitalist receives a certain price for the commodity the worker made. The capitalist builds up capital by paying the worker less than that price. In this way, the capitalist exploits the worker's labor by:


title: Marxism

text: Here is an example of exploitation of labor. Jane is a shoemaker. She works for Michael, who owns a shoe factory that can make 60 pairs of shoes in a day. Jane makes 60 pairs of shoes every day. Michael pays Jane $20 a day. However, Michael sells each pair of shoes for $2 each. This means he makes $120 in a day. After he pays Jane her $20 wage, Michael has $100 left over. However he then has to pay for materials which cost $1 for each pair, so that's $60 each day. Then running expenses of the factory cost him $10 a day. So he only gets $30 at the end of the day for managing the business. This remaining wealth is called "Profit" or "Surplus [extra] Value." In other words, even though Jane makes 60 shoes every day, she only gets paid the value of 10 pairs of shoes. The rest of the day, while she is making the other 50 shoes, she is creating money for her boss. Her labor is making him richer and helping him earn money.


title: Marxism

text: It is this Surplus Value, or Profit, which Marxism thinks as an exploitation of labor. This exploitation allows the smaller class (capitalists) to live without working while making a profit, while the bigger class (the workers) have to work for the capitalists to survive under usually poor working conditions.


title: Marxism

text: Marxism says that factories, tools, and work places cannot create new value on their own. They are like a blueberry bush: it has no value on its own. People have to create that value by laboring. For example, someone spends a day picking blueberries. Those blueberries can now be traded or eaten because of the labor that was put in to pick them.


title: Marxism

text: Marxist thinking claims that capitalists and workers are constantly struggling. They call this "Dialectical Materialism." This is the idea that the history of humans is the history of conflict between classes. Different classes with different interests argue or fight each other. Social change (or in its absence, social stagnation) is the result.


title: Marxism

text: Marxism says that capitalists want to exploit the workers as much as possible and make their pay as low as they can. The capitalists do this to create as much profit for themselves as possible, as quickly as possible. Workers, on the other hand, have to struggle to keep their wages up and to keep the "rate of exploitation" low, so that they can live more peaceful lives. This is what Marxism calls "class struggle": where workers and their bosses fight against each other to gain for themselves.


title: Marxism

text: Marxists think that all of written human history has been divided by economic classes. One example is feudal society (a medieval society controlled by feudal lords and nobles). The ruling class got their power and wealth from the labor of peasants (farmers). But as peasants demanded more and more for themselves, small shopkeepers and tradespeople began to appear. Many of these people formed guilds and eventually began to employ workers. These workers were able to gain wealth for themselves at these jobs. These historical events created capitalism.


title: Marxism

text: In this way, Marxists think that history has been pushed forward by class struggle. They think that change will be born from this struggle, just like capitalism was. However, they also think that capitalism will give way to communism; as the exploitation of workers becomes worse it will lead workers to revolt against their capitalist rulers.


title: Marxism

text: The core of Marxist thinking is called Materialism. Materialism is a philosophical view that says that communities develop from the "ground up". It says that the "higher" qualities of culture (like art, manners, customs, and religions) are actually founded on the "lower" or simpler qualities of life. These qualities include having enough of what people need to survive, like food and shelter; who has money and what they have to do to get it; who is allowed to work, and who is forced to work.


title: Marxism

text: Changes in the higher qualities of culture (sometimes called the "Superstructure") are often linked to changes in the lower qualities of life (sometimes called the "Base"). One example is that in medieval times, people thought "honor" or duty to people with more power than them was very important. Today, in Western countries, many people see ambition (being someone who works hard for their own goals) as more important. This is because, in medieval times, people worked their entire lives under lords who depended on them not only for work but for war. Today, people work for themselves more, and our society lets some people move up from being poor to being rich. In this case, what people see as good and important depends on how the rulers get value out of their workers.


title: Marxism

text: Marxism recognizes that in earlier time periods, we lived first under rulers who owned everything. Then we lived under lords who owned land with workers who lived and worked on that land. In Marx's time, people lived under governments that allowed many people to own property. Eventually, Marxists believe that we will move to a society where everyone owns everything in common. This will be called communism.


title: Marxism

text: In other words, human society has always been based on the economic forces that human beings can control. For Marxism, this means that each society would take its form based on its "mode of production."


title: Marxism

text: Marxists believe that humans' ability to produce goods and services today means people can move beyond the conflicts of a society that is divided into classes. Many Marxists believe that there will always be revolts and, with the right conditions, revolutions. In these revolutions, the workers will fight the capitalists. If they win, they will set up a socialist "workers' state" (a form of government where the workers are the rulers of society). This workers' state will only be temporary. Its job will be to take power away from the capitalists, until all the capitalist countries in the world are defeated, and social classes no longer exist.


title: Marxism

text: Marxists believe that if the working class makes itself the ruling class, and destroys the basis for class society (private property, or what Marx called "Bourgeois Property"), there will be a "classless society." In a Marxist society, no social classes are in conflict, and there is no government anymore. The state will no longer be needed. There would be no countries. The world will have no borders. There will be communes around the world. Workers will organize production of goods and services based on what people need, not based on profits.


title: Marxism

text: Some Marxists say that modern "communism" is not communism at all. They say that "communist" countries like the Soviet Union, the People's Republic of China, Cuba, and Vietnam are really using different forms of capitalism, often with heavily "nationalized" industries. A thinker named Tony Cliff was one of the biggest supporters of these ideas. He wrote that states like the Soviet Union and Communist China (before 1980) were "State-Capitalist."


title: Marxism

text: Not all communists, socialists, or Marxists agree on this question. However, many strong supporters of Marxism agree that:

text: Over 55 million people live in England (2015 estimate). This is 84% of the population of the UK. The capital city of England is London, which is also the biggest city in the country. Other large cities in England are Birmingham, Liverpool, Manchester and Leeds.


title: England

text: The English flag is a red cross on a white background. This cross is the cross of Saint George, who is the patron saint of England. Some other symbols used for England are a red rose and three lions.


title: England

text: The earliest known evidence of human presence in the area now known as England was that of "Homo antecessor", about 780,000 years ago. The oldest proto-human bones discovered in England date to 500,000 years ago. The Beaker culture arrived around 2,500 BC. They used drinking and food vessels made from clay, and vessels used as reduction pots to smelt copper ores.


title: England

text: It was during this time that major Neolithic monuments such as Stonehenge and Avebury were constructed. By heating together tin and copper, plentiful in the area, the Beaker culture people made bronze. Later on they made iron from iron ores. The development of iron smelting allowed the construction of better ploughs, advancing agriculture (for instance, with Celtic fields), as well as the production of more effective weapons.


title: England

text: During the Iron Age, Celtic culture, deriving from the Hallstatt and La Tène cultures, arrived from Central Europe. Brythonic was the spoken language during this time. Society was tribal; according to Ptolemy's "Geographia" there were around 20 tribes in the area. Earlier divisions are unknown because the Britons were not literate. Like other regions on the edge of the Empire, Britain had long enjoyed trading links with the Romans. Julius Caesar of the Roman Republic attempted to invade twice in 55 BC; although largely unsuccessful, he managed to set up a client king from the Trinovantes.


title: England

text: The Romans invaded Britain in 43 AD during the reign of Emperor Claudius, later conquering much of Britain. The area was added to the Roman Empire as the Province of Britannia. The best-known of the native tribes who attempted to resist were the Catuvellauni led by Caratacus. Later, an uprising led by Boudica, Queen of the Iceni, ended with Boudica's suicide following her defeat at the Battle of Watling Street.


title: England

text: The author of one study of Roman Britain suggested that from 43 AD to 84 AD, the Roman invaders killed somewhere between 100,000 and 250,000 people from a population of perhaps 2,000,000. The Greco-Roman culture prevailed with the introduction of Roman law, Roman architecture, aqueducts, sewers, many agricultural items and silk. In the 3rd century, Emperor Septimius Severus died at Eboracum (now York), where Constantine was proclaimed emperor a century later. Rich in resource and goods, Roman Britain was a wealthy and flourishing trading province of the Roman Empire.


title: England

text: Roman military withdrawals left Britain open to invasion by pagan, seafaring warriors from north-western continental Europe, chiefly the Saxons, Angles, Jutes and Frisians who had long raided the coasts of the Roman province. These groups then began to settle in increasing numbers over the course of the fifth and sixth centuries, initially in the eastern part of the country. Their advance was contained for some decades after the Britons' victory at the Battle of Mount Badon. Later it resumed, overrunning the fertile lowlands of Britain and, by the end of the 6th century, reducing the area under Brittonic control to a series of enclaves in the more rugged country to the west. Contemporary texts describing this period are extremely scarce, giving rise to its description as a Dark Age.


title: England

text: The nature and progress of the Anglo-Saxon settlement of Britain is unclear. It occurred on a large scale in the south and east but was less substantial to the north and west, where Celtic languages continued to be spoken even in areas under Anglo-Saxon control. Roman-dominated Christianity had, in general, been replaced in the conquered territories by Anglo-Saxon paganism, but was reintroduced by missionaries from Rome led by Augustine from 597 onwards. Disputes between the Roman- and Celtic-dominated forms of Christianity ended in victory for the Roman tradition at the Council of Whitby (664), which was superficially about tonsures (clerical haircuts) and the date of Easter, but more significantly, about the differences in Roman and Celtic forms of authority, theology, and practice.


title: England

text: The early Anglo-Saxon period includes the creation of an English nation, with many of the aspects that survive today, including regional government of shires and hundreds. Christianity was established with a great flowering of literature and language. Charters and laws were also established. Anglo-Saxon material culture can still be seen in architecture, dress styles, illuminated texts, metalwork and other art. Behind the symbolic nature of these cultural emblems, there are strong elements of tribal and lordship ties. The lands ruled by the incomers seem to have been fragmented into numerous tribal territories, but by the 7th century, when substantial evidence of the situation again becomes available, these had coalesced into roughly a dozen kingdoms including Northumbria, Mercia, Wessex, East Anglia, Kent and Sussex. Over the following centuries, this process of political consolidation continued.


title: England

text: The 7th century saw a struggle for hegemony between Northumbria and Mercia, which in the 8th century gave way to Mercian preeminence. In the early 9th century Mercia was displaced as the foremost kingdom by Wessex. Later in that century escalating attacks by the Danes culminated in the conquest of the north and east of England, overthrowing the kingdoms of Northumbria, Mercia and East Anglia. Wessex under Alfred the Great was left as the only surviving English kingdom, and under his successors, it steadily expanded at the expense of the kingdoms of the Danelaw. After many battles, King Alfred the Great of Wessex became king of the whole of England. The old kingdoms (Mercia, Northumbria, etc.) became provinces, called "Earldoms" and each governed by an Earl. By AD 927 Alfred's grandson Athelstan was the king of all of England not controlled by the Danes. War with the Danes continued and from 1016 to 1042. The king of Denmark (Knut or Canute), died in 1035, and then his sons ruled England.


title: England

text: This brought about the political unification of England, first accomplished under Æthelstan in 927 and definitively established after further conflicts by Eadred in 953. A fresh wave of Scandinavian attacks from the late 10th century ended with the conquest of this united kingdom by Sweyn Forkbeard in 1013 and again by his son Cnut in 1016, turning it into the centre of a short-lived North Sea Empire that also included Denmark and Norway. However, the native royal dynasty was restored with the accession of Edward the Confessor in 1042. When King Edward the Confessor died, Harold Godwinson (the Earl of Wessex) became king. William the Conqueror, Duke of Normandy (today part of northern France), said that Harold had promised to make William the king. He invaded England and fought King Harold at the Battle of Hastings in 1066. William won, and became king of England.


title: England

text: Subsequently, the House of Plantagenet from Anjou inherited the English throne under Henry II, adding England to the budding Angevin Empire of fiefs the family had inherited in France including Aquitaine. They reigned for three centuries, some noted monarchs being Richard I, Edward I, Edward III and Henry V. The period saw changes in trade and legislation, including the signing of the "Magna Carta", an English legal charter used to limit the sovereign's powers by law and protect the privileges of freemen. Catholic monasticism flourished, providing philosophers, and the universities of Oxford and Cambridge were founded with royal patronage. The Principality of Wales became a Plantagenet fief during the 13th century and the Lordship of Ireland was given to the English monarchy by the Pope.


title: England

text: During the 14th century, the Plantagenets and the House of Valois both claimed to be legitimate claimants to the House of Capet and with it France; the two powers clashed in the Hundred Years' War. The Black Death epidemic hit England; starting in 1348, it eventually killed up to half of England's inhabitants. From 1453 to 1487 civil war occurred between two branches of the royal family – the Yorkists and Lancastrians – known as the Wars of the Roses. Eventually it led to the Yorkists losing the throne entirely to a Welsh noble family the Tudors, a branch of the Lancastrians headed by Henry Tudor who invaded with Welsh and Breton mercenaries, gaining victory at the Battle of Bosworth Field where the Yorkist king Richard III was killed.


title: England

text: For several centuries the religion of England was Roman Catholicism. The bishops (church leaders) of England and all their churches obeyed the Pope and the church in Rome. During the Protestant Reformation many did not agree with this. In the 1530s, the Pope told King Henry VIII that he could not divorce his wife. King Henry VIII created the Church of England (a "Protestant" church) partly so that he could divorce his wife. He made Protestantism the official church in England. For the next 200 years, there was struggle over whether the King (or Queen) of England should be "Roman Catholic" or "Protestant".


title: England

text: Queen Elizabeth I was Henry's second daughter. She was a powerful queen who ruled for more than 40 years. Elizabethan England represented the apogee of the English Renaissance and saw the flowering of art, poetry, music and literature. The era is most famous for its drama, theatre and playwrights. When Queen Elizabeth I died, she had no children, and in 1603 James VI of Scotland (the son of Mary, Queen of Scots) became King James I of England. He called his two countries "Great Britain", but they were still separate countries with their own parliaments and laws, even though they were in personal union. They shared the same monarch.


title: England

text: James' son, Charles I and the English Parliament fought each other in the English Civil War (Scotland and Ireland were involved as well, but the story is complicated!). Oliver Cromwell became leader of the Parliamentary Army (the "Roundheads") and defeated the Royalist Army (the "Cavaliers"). King Charles was beheaded in 1649 and Oliver Cromwell became dictator ("Lord Protector"). When Cromwell died, his son Richard was not strong enough to rule, and Charles II, the son of Charles I, was invited to come to England and be king in 1660.


title: England

text: When King Charles II died, his brother James II was the next king. A lot of people did not like James because he was Roman Catholic. William of Orange was invited to invade England. He was the ruler of part of the Netherlands and husband of Mary, the daughter of King James. Many people welcomed William because he was a Protestant. James left the country without a fight and Parliament asked William and Mary to become King and Queen together. When Mary II of England died, William ruled alone. Queen Mary's sister Anne became the next queen. While she was queen, England and Scotland were officially joined as one country. This was called the Acts of Union 1707. It also merged their separate parliaments. The parliament in London now included Scottish Members of Parliament ("MPs"), and was called the Parliament of Great Britain.


title: England

text: After this, the history of England becomes the history of Great Britain and United Kingdom. Under the newly formed Kingdom of Great Britain, output from the Royal Society and other English initiatives combined with the Scottish Enlightenment created innovations in science and engineering, while the enormous growth in British overseas trade protected by the Royal Navy paved the way for the establishment of the British Empire. Domestically it drove the Industrial Revolution, a period of profound change in the socioeconomic and cultural conditions of England, resulting in industrialised agriculture, manufacture, engineering and mining, as well as new and pioneering road, rail and water networks to facilitate their expansion and development.


title: England

text: The United Kingdom was formed in 1800, when the Irish Parliament merged with the British one. later on, many in Ireland fought against this merger. The result was the separation of the Republic of Ireland. This is not the whole island of Ireland. The rest of the island, Northern Ireland, is now the only part of Ireland still in the UK. England is the only country of UK not to have its own government, Parliament or Assembly, but is governed by Parliament of the United Kingdom. Seats in Parliament are decided by the number of electors in the various parts of the UK.


title: England

text: England is the largest part of the island of Great Britain, and it is also the largest constituent country of the United Kingdom. Scotland and Wales are also part of Great Britain (and the UK), Scotland to the north and Wales to the west. To the east and south, and part of the west, England is bordered by sea. France is to the south, separated by the English Channel. The Channel Tunnel, (Chunnel) under the English Channel, connects England to northern France (and the rest of mainland Europe). Ireland is a large island to the west, divided into Northern Ireland which is part of the United Kingdom, and the Republic of Ireland.


title: England

text: London is the largest city and the capital. The longest river in England is the River Severn. Other large rivers are the Thames (which runs through London), the Trent and the Humber.


title: England

text: In geological terms, the Pennines, known as the "backbone of England", are the oldest range of mountains in the country, originating from the end of the Paleozoic Era around 300 million years ago. Most of England's landscape consists of low hills and plains, with upland and mountainous terrain in the north and west of the country.


title: England

text: The English Lowlands are in the central and southern regions of the country, consisting of green rolling hills, including the Cotswold Hills, Chiltern Hills, North and South Downs; where they meet the sea they form white rock exposures such as the cliffs of Dover. This also includes relatively flat plains such as the Salisbury Plain, Somerset Levels, South Coast Plain and The Fens.


title: England

text: The United Kingdom is reducing greenhouse gas emissions. It has met Kyoto Protocol target of a 12.5% reduction from 1990 levels and intends to meet the legally binding target of a 20% cut in emissions by 2010. In 2019, the British Parliament became the first national government in the world to officially declare a climate emergency.


title: England

text: England has been central to many aspects of the modern world. Global exploration and trade, the British Empire, modern science, modern agriculture, railways, the Industrial Revolution, the development of modern representative democracy. In all these developments England was deeply involved. In some of them, such as the Industrial Revolution, England was the place that modern developments first occurred.


title: England

text: The Royal Society is a society for science and scientists. It was founded in 1660 by Charles II. It is the oldest society of its kind still in existence.


title: England

text: The English language is a West Germanic language spoken in many countries around the world. With around 380 million native speakers, it is the second most spoken language in the world, as a native language. As many as a billion people speak it as a second language. English is an influence on, and has been influenced by, many different languages.


title: England

text: William Shakespeare was an English playwright. He wrote plays in the late 16th century. Some of his plays were "Romeo and Juliet" and "Macbeth". In the 19th century, Jane Austen and Charles Dickens were novelists. Twentieth century writers include the science fiction novelist H.G. Wells and J.R.R. Tolkien. The children's fantasy "Harry Potter" series was written by J.K. Rowling. Aldous Huxley was also from the United Kingdom.


title: England

text: English language literature is written by authors from many countries. Eight people from the United Kingdom have won the Nobel Prize in Literature.


title: England

text: All of Great Britain has an oceanic climate. There can be a temperature difference of 510°c between the north and the south (the north is generally colder), and there is often snow in the north before there is in the south.


title: England

text: The prevailing wind for most of the year is from the Atlantic, to the west of England. Therefore, there is more rain on the western side of the country. The east is colder and drier than the west. The country usually has a mild climate because the Gulf Stream to the western side is warm water. The climate is warmer than it was 200 years ago, and now ice and snow are rare in the southern part of the country. Occasionally, air from the Arctic Circle comes down the eastern side of the country and the temperature can drop below 0C.


title: England

text: As part of the United Kingdom, the basic political system in England is a constitutional monarchy and parliamentary system. It has a monarch (meaning a king or queen is the head of that country). The head of state is King Charles III, who is became King of the United Kingdom of Great Britain and Northern Ireland upon his Mother's death on 9/8/2022, after her historical 70 year reign. In the House of Commons which is the lower house of the British Parliament based at the Palace of Westminster, there are 532 Members of Parliament (MPs) for constituencies in England, out of the 650 total.


title: England

text: The English people are represented by members of Parliament, not ruled by monarchs. After the English Civil War, Oliver Cromwell became Lord Protector, and the monarchy was disbanded. Although the monarchy was restored after his death, the Crown slowly became the secondary power, and Parliament the first. Members of Parliament (called MPs) were elected, but until the early twentieth century, only men who owned property could vote. In the nineteenth century, more people were given suffrage. But in 1928, all men and women got the vote: this is called universal suffrage. Parliament is in Westminster in London, but it has power over the whole of the United Kingdom.


title: England

text: Almost all members of Parliament belong to political parties. The biggest parties are the Conservative Party, Labour Party, Liberal Democrats and Green Party. Members of the same party agree to act and vote more or less together. A party with more than half the seats (a majority) forms the government; the leader of the party becomes the Prime Minister, who then appoints other ministers. Because the government has a majority in Parliament, it can normally control what laws are passed.


title: England

text: England's economy is one of the largest and most dynamic in the world, with an average GDP per capita of £28,100 or $36,000.


title: England

text: Usually regarded as a mixed market economy, it has adopted many free market principles, yet maintains an advanced social welfare infrastructure. The official currency in England is the pound sterling, whose ISO 4217 code is GBP. Taxation in England is quite competitive when compared to much of the rest of Europe – as of 2014 the basic rate of personal tax is 20% on taxable income up to £31,865 above the personal tax-free allowance (normally £10,000), and 40% on any additional earnings above that amount.


title: England

text: The economy of England is the largest part of the UK's economy, which has the 18th highest GDP PPP per capita in the world. England is a leader in the chemical and pharmaceutical sectors and in key technical industries, particularly aerospace, the arms industry, and the manufacturing side of the software industry. London, home to the London Stock Exchange, the United Kingdom's main stock exchange and the largest in Europe, is England's financial centre, with 100 of Europe's 500 largest corporations being based there. London is the largest financial centre in Europe, and as of 2014 is the second largest in the world. Manchester is the largest financial and professional services sector outside London and is the mid tier private equity capital of Europe as well as one of the growing technology hubs of Europe.


title: England

text: The Greater London Built-up Area is by far the largest urban area in England and one of the busiest cities in the world. It is considered a global city and has a population larger than any other country in the United Kingdom besides England itself.


title: England

text: Other urban areas of considerable size and influence tend to be in northern England or the English Midlands. There are 52 settlements which have designated city status in England, while the wider United Kingdom has 70. City status in England is granted by the monarch to a select group of communities.


title: England

text: While many cities in England are quite large, such as Birmingham, Sheffield, Manchester, Liverpool, Leeds, Newcastle, Bradford, Nottingham, population size is not a prerequisite for city status. Traditionally the status was given to towns with diocesan cathedrals, so there are smaller cities like Wells, Ely, Ripon, Truro and Chichester.


title: England

text: State primary schools and secondary schools exist. These consist of academy schools, grammar schools, foundation schools, faith schools, free schools, studio schools, university technical colleges and city technology colleges. The most common specialist schools are performing arts schools, science schools, maths schools, business schools and technology schools. Independent public or prep schools also exist. Eton College and Harrow School are the best known independent schools.


title: England

text: The National Curriculum was introduced in 1988, to give pupils a broad and balanced curriculum. The school curriculum aims to promote the spiritual, moral, cultural, mental and physical development of pupils. Its purpose is to prepare them for the opportunities, responsibilities and experiences of later life. The basic areas of learning covers English literature, English language, maths, science, art and design, citizenship, religious education, geography, history, computing, design and technology, ancient and modern foreign languages, music and physical education.


title: England

text: Many prominent people who have reached the top in their fields have been products of English higher education. There have been universities in England since the Middle Ages. Ancient universities started in this time and in the Renaissance. The two oldest and most prestigious universities are Oxford University and Cambridge University. Imperial College, University College London and Manchester University are also highly rated by independent lists. There are now about a hundred universities.


title: England

text: Road traffic in the United Kingdom drives on the left hand side of the road (unlike the Americas and most of Europe), and the driver steers from the right hand side of the vehicle. The road network on the island of Great Britain is extensive, with most local and rural roads having evolved from Roman and Medieval times.


title: England

text: The system of rail transport was invented in England, so it has the oldest railway network in the world. It was built mostly during the Victorian era. The extensive railway network is managed by the state-owned public body Great British Railways (GBR). The system of underground railways in London, known as the Tube, has been copied by many other cities around the globe. England is home to the largest airport and is one of the most important international hubs in the world.


title: England

text: The BBC is an organisation in the United Kingdom. It broadcasts in the United Kingdom and other countries on television, radio and the Internet. The BBC also sells its programmes to other broadcasting companies around world. The organisation is run by a group of twelve governors who have been given the job by the Queen, on the advice of government ministers. The BBC is established under a royal charter, which allows the BBC to broadcast.


title: England

text: National newspapers produced in England include "The Times, The Guardian" and the "Financial Times." Magazines and journals published in England that have achieved worldwide circulation include "Nature, New Scientist, The Spectator, Prospect, NME" and "The Economis"t.


title: England

text: English culture can be compared with Northern European countries, in the way that it is considered a bad thing to show off, as opposed to the US, where this is more acceptable. Humour, tradition and good manners are characteristics commonly associated with being English.


title: England

text: England has a strong sporting heritage, and during the 19th century codified many sports that are now played around the world. Sports originating in England include association football, cricket, rugby union, rugby league, tennis, boxing, badminton, squash, rounders, hockey, snooker, billiards, darts, table tennis, bowls, netball, thoroughbred horseracing, and greyhound racing. It has helped the development of golf, sailing and Formula One.


title: England

text: The English football team won the World Cup in 1966. They came close in Italy 1990, closely losing in the semi-final against West Germany on penalties. In the 2006 World Cup they got to the quarter finals, then lost to Portugal after penalty kicks. In the 2018 FIFA World Cup, they came close again only to be knocked out in the semi-final, losing 2-1 to Croatia. After winning the 2019 Cricket World Cup, England became the first country to win the World Cups in football, rugby union and cricket.


title: England

text: England is divided into 48 ceremonial counties, which are also known as geographic counties. The counties of England are areas used for different purposes, which include administrative, geographical, cultural and political demarcation. The original county structure has its origins in the Middle Ages.


title: England

text: The historic counties of Yorkshire, Cumberland, Westmorland, Huntingdonshire and Middlesex are the five defunct ceremonial counties which were historically counties.


title: England

text: With their abolition as ceremonial counties, Yorkshire is divided for that purpose into the East Riding of Yorkshire, North Yorkshire, South Yorkshire and West Yorkshire, Cumberland and Westmorland were combined with a former exclave of Lancashire to form Cumbria, Huntingdonshire merged into Cambridgeshire, and the vast majority of Middlesex became part of Greater London.


title: England

text: There is no well-established series of official symbols or flags covering all the counties. From 1889 the newly-created county councils could apply to the College of Arms for coats of arms. A recent series of flags, with varying levels of official adoption, have been established in many of the counties by competition or public poll. County days are a recent innovation in some areas. There are seventeen first-class county cricket teams that are based on historical English counties.


title: England

text: Twelve of the 51 cities in England are in metropolitan counties and their city councils are single-tier metropolitan district councils. Outside the metropolitan counties eleven cities are unitary authorities, and fifteen have ordinary district councils, which are subordinate to their local county council.


title: Red Fort

text: The Red Fort (Lal Qila) is a monument built in 1648 that rises above Old Delhi. It was built by the Mughal Emperor Shah Jahan. The fort is located in the centre of Delhi, India. It is made of red stone and marble. It was built on the right bank of the Yamuna River.


title: Red Fort

text: The Red Fort was originally referred to as "Qila-i-Mubarak" (the blessed fort), because it was the residence of the royal family. The layout of the Red Fort was organised to keep and integrate this site with the Salimgarh Fort. The planning and aesthetics of the Red Fort represent the high point in Mughal creativity which happened during the reign of Emperor Shah Jahan. This Fort has had many additions after its construction by Emperor Shah Jahan. It is a World Heritage Site. it is made out of red sandstone.

title: Volcano

text: A volcano is a mountain that has lava (hot, liquid rock) coming out from a magma chamber under the ground, or did have in the past. Volcanoes are formed by the movement of tectonic plates.


title: Volcano

text: The Earth's crust has 17 major, rigid tectonic plates. These float on a hotter, softer layer in its mantle. Volcanoes are often found where tectonic plates are moving apart or coming together.


title: Volcano

text: Volcanoes can also form where there is stretching and thinning of the crust's plates, e.g., in the East African Rift. Volcanoes are usually not found where two tectonic plates slide past one another.


title: Volcano

text: Volcanism away from plate boundaries is caused by mantle plumes. These so-called "hotspots", for example Hawaii, are thought to arise from upwelling magma from the core–mantle boundary, 3,000 km deep in the Earth.


title: Volcano

text: Most volcanoes have a volcanic crater at the top. When a volcano is active, materials come out of it. The materials include lava, steam, gaseous sulfur compounds, ash and broken rock pieces.


title: Volcano

text: When there is enough pressure, the volcano erupts. Some volcanic eruptions blow off the top of the volcano. Sometimes, the magma comes out quickly and sometimes it comes slowly. Some eruptions come out at a side instead of the top.


title: Volcano

text: Volcanologists are scientists who study volcanoes using methods from geology, chemistry, geography, mineralogy, physics and sociology.


title: Volcano

text: The world's biggest volcano is named Mauna Loa in Hawaii. Mauna Loa is part of the five volcanoes on Hawaii's 'Big Island'. The most recent time this volcano erupted was in 1984. It erupted 33 times in the last 170 years. Like all the other Hawaiian volcanoes, Mauna Loa was created by the movement of the Pacific tectonic plate which moved over the Hawaii hotspot in the Earth's mantle. Mauna Loa is 4,196 meters tall. It is a shield volcano. The largest recent eruption from Mauna Loa left a lava trail long.


title: Volcano

text: The lava and pyroclastic material (clouds of ash, lava fragments and vapor) that comes out from volcanoes can make many different kinds of land shapes. There are two basic kinds of volcanoes.


title: Volcano

text: Shield volcanoes are built out of layers of lava from continual eruptions (without explosions). Because the lava is so fluid, it spreads out, often over a wide area. Shield volcanoes do not grow to a great height, and the layers of lava spread out to give the volcano gently sloping sides. Shield volcanoes can produce huge areas of basalt, which is usually what lava is when cooled.


title: Volcano

text: The base of the volcano increases in size over successive eruptions where solidified lava spreads out and accumulates. Some of the world's largest volcanoes are shield volcanoes.


title: Volcano

text: Even though their sides are not very "steep", shield volcanoes can be huge. Mauna Kea in Hawaii is the biggest mountain on Earth if it is measured from its base on the floor of the sea.


title: Volcano

text: A stratovolcano, also known as a composite volcano, is a tall, conical volcano. It is built up of many layers of hardened lava, tephra, pumice, and volcanic ash.


title: Volcano

text: Unlike shield volcanoes, stratovolcanoes have a steep profile and periodic eruptions. The lava that flows from stratovolcanoes cools and hardens before spreading far. It is sticky, that is, it has high viscosity. The magma forming this lava is often felsic, with high-to-intermediate levels of silica, and less mafic magma. Big felsic lava flows are uncommon, but have travelled as far as .


title: Volcano

text: Two famous stratovolcanoes are Japan's Mount Fuji, and Vesuvius. Both have big bases and steep sides that get steeper and steeper as it goes near the top. Vesuvius is famous for its destruction of the towns Pompeii and Herculaneum in 79 AD, killing thousands.


title: Volcano

text: A caldera is a basin-like feature formed by collapse of land after a volcanic eruption. This happens after a huge stratovolcano blows its top off. The base of the crater then sinks, leaving a caldera where the top of the volcano was before. Krakatoa, best known for its catastrophic eruption in 1883, is much smaller now.


title: Volcano

text: Volcanoes are made when two tectonic plates come together. When these two plates meet, one of them (usually the oceanic plate) goes under the continental plate. This is the process of subduction. Afterwards, it melts and makes magma (inside the magma chamber), and the pressure builds up until the magma bursts through the Earth's crust.


title: Volcano

text: The second way is when a tectonic plate moves over a hot spot in the Earth's crust. The hot spot works its way through the crust until it breaks through. The caldera of Yellowstone Park was formed in that way; so were the Hawaiian Islands.


title: Volcano

text: A traditional way to classify or identify volcanoes is by its pattern of eruptions. Those volcanoes which may erupt again at any time are called active. Those that are now quiet are called dormant (inactive). Those volcanoes which have not erupted in historical times are called extinct.


title: Volcano

text: An active volcano is currently erupting, or it has erupted in the last 10,000 years. An example of an active volcano is Mount St. Helens in the United States (US).


title: Volcano

text: A dormant volcano is "sleeping," but it could awaken in the future. Mount Rainier in the United States is considered dormant.


title: Volcano

text: An extinct volcano has not erupted in the past 10,000 years. Edinburgh Castle in Scotland sits on top of an extinct volcano.


title: Volcano

text: The Earth's largest volcano has been discovered. It is 2 km below the sea on an underwater plateau known as the Shatsky Rise. This is about 1,600 km east of Japan. The previous record-holder, Mauna Loa in Hawaii, is still the largest volcano on land.


title: Volcano

text: The 310,000 km (119,000 sq mi) volcano, Tamu Massif, is comparable in size to Mars' vast Olympus Mons volcano, which is the largest known volcano in the Solar System. It was formed about 145 million years ago when massive lava flows erupted from the centre of the volcano to form a broad, shield-like feature. That suggests the volcano produced a flood basalt eruption.


title: Volcano

text: The Higgs field is a field of energy that is thought to exist in every region of the universe. The field is accompanied by a fundamental particle known as the Higgs boson, which is used by the field to continuously interact with other particles, such as the electron. Particles that interact with the field are "given" mass and, in a similar fashion to an object passing through a treacle (or molasses), will become slower as they pass through it. The result of a particle "gaining" mass from the field is the prevention of its ability to travel at the speed of light.


title: Higgs field

text: Mass itself is not generated by the Higgs field; the act of creating matter or energy from nothing would violate the laws of conservation. Mass is, however, gained by particles via their Higgs field interactions with the Higgs Boson. Higgs bosons contain the relative mass in the form of energy and once the field has endowed a formerly massless particle, the particle in question will slow down as it has now become "heavy".


title: Higgs field

text: If the Higgs field did not exist, particles would not have the mass required to attract one another, and would float around freely at light speed.


title: Higgs field

text: Giving mass to an object is referred to as the Higgs effect. This effect will transfer mass or energy to any particle that passes through it. Light that passes through it gains energy, not mass, because its wave form doesn't have mass, while its particle form constantly travels at light speed.


title: Higgs field

text: The Higgs effect was first theorized in 1964 by writers of the PRL symmetry breaking papers. In 1964, three teams wrote scientific papers which proposed related but different approaches to explain how mass could arise in local gauge theories.


title: Higgs field

text: In 2013 the Higgs boson, and implicitly the Higgs effect, were tentatively proven at the Large Hadron Collider (and the Higgs boson was discovered on July 4, 2012). The effect was seen as finding a missing piece of the Standard Model.


title: Higgs field

text: According to gauge theory (the theory underlying the Standard Model), all force-carrying particles should be massless. However, the force-particles that mediate the weak force have mass. This is due to the Higgs effect, which breaks the SU(2) symmetry; (SU stands for special unitary, a type of matrix, and 2 refers to the size of the matrices involved).


title: Higgs field

text: A symmetry of a system is an operation done to a system, such as rotation or displacement, that leaves the system fundamentally unchanged. A symmetry also provides a rule for how something should always act unless acted on by an outside force. An example is a Rubik's Cube. If we take a Rubik's cube and scrambled it by making whatever moves we want, it is still possible to solve it. Since each move we make still leaves the Rubik's cube solvable, we can say that these moves are 'symmetries' of the Rubik's cube. Together, they form what we call the symmetry group of the Rubik's cube. Making any of these moves doesn't change the puzzle, always leaving it solvable. But, we can break this symmetry by doing something like taking the cube apart, and putting it back together in a completely wrong way. No matter what moves we try now, it is not possible to solve the cube. Breaking the cube apart and putting it back together in the wrong way is the 'outside force': Without this outside force, nothing we do to the cube makes it unsolvable. The symmetry of the Rubik's cube is that it stays solvable whatever moves we make, as long as we do not take apart the cube.


title: Higgs field

text: The way that the SU(2) symmetry is broken is known as "spontaneous symmetry breaking". Spontaneous means random or unexpected, Symmetries are the rules that are being changed, and Breaking refers to the fact that the symmetries are no longer the same. The result of spontaneously breaking the SU(2) symmetry can be a Higgs boson.


title: Higgs field

text: The Higgs effect occurs because nature "tends" towards the lowest energy state. The Higgs effect will happen because gauge bosons near a Higgs field will want to be in their lowest energy states, and this would break at least one symmetry.


title: Higgs field

text: To justify giving mass to a would-be massless particle, scientists were forced to do something out of the ordinary. They assumed that vacuums (empty space) actually "had" energy, and that way, if a particle that we think of as massless were to enter it, the energy from the vacuum would be transferred into that particle, giving it mass. A mathematician named Jeffrey Goldstone proved that if you violate a symmetry (for example, a symmetry with a Rubik's cube would be if you state that the corners must always be rotated 0 or 3 times to be solvable (it works)), a reaction will occur. In the case of the Rubik's cube, the cube will become unsolvable if violated. In the case of the Higgs field, something named after Jeffrey Goldstone (and another scientist who worked with him named Yoichiro Nambu) is produced, a Nambu-Goldstone boson. This is an excited or energetic form of the vacuum, which can be graphed revealing that shown above. This was first explained by Peter Higgs.


title: Constitution of India

text: The Constitution of India is the supreme law in India . A Constitution is a set of rules and regulations guiding the administration of a country. The constitution of India is the framework for political principles, procedures and powers of the government. It is also the longest constitution in the world with 395 articles and 12 schedules. Originally it consisted of 395 Articles arranged under 22 Parts and 8 Schedules. Today after many amendments, it has 470 Articles and 12 schedules and 25 parts (According to 2021). The constitution was written on 26 November 1949, and was made the center of law on 26 January 1950.


title: Constitution of India

text: India had to face many problems after independence. Rehabilitating the refugees who migrated from Pakistan, merging the princely states, maintenance of law and order were the major challenges. Sardar Patel successfully achieved the merger of the princely states and provinces with the Union of India. Even the challenge of framing a constitution in order to enable govern the country was also fulfilled.


title: Constitution of India

text: The recommendations of the Motilal Nehru Committee and the decisions taken by the meeting of National Congress at Karachi prepared for the formation of a Constituent Assembly.


title: Constitution of India

text: The first meeting of the new Constituent Assembly was conducted on 9th of December, 1946. The next meeting conducted in 11th of December, 1946 under the chairmanship of Dr. Rajendra Prasad. Participants included Jawaharlal Nehru, Sardar Vallabhai Patel, Dr. B. R. Ambedkar and Sarojini Naidu. Dr. Ambedkar, chairman of the Drafting Committee, is often called the father of the Indian Constitution.


title: Constitution of India

text: The Constituent Assembly, which came into existence on 11th of December 1946, had 145 meetings and framed a draft constitution. During these discussions, the various laws proposed by the British Government in 1909, 1919 and 1935, the British Parliamentary system, the American Bill of Rights, the Social Directive Policies of Ireland were studied and some parts of those were written in the Constitution. Finally, the Indian Constitution was approved on 26th of November, 1949 and came into effect on 26th of January, 1950. This day (January 26) is celebrated as the 'Republic Day' in India.


title: Television

text: A television set (also known as a television receiver or televisor or simply a television, TV set, TV receiver or TV) is a machine with a screen or set of lenses. Televisions receive broadcasting signals and change them into pictures and sound. The word "television" comes from the words tele (Greek for "far away") and vision ("sight").


title: Television

text: Sometimes a television can look like a box. Older TVs had a large cathode ray tube in a large wooden frame and sat on the floor like furniture. Newer TVs are much lighter and flatter.


title: Television

text: A TV can show pictures from many television networks. Computers and mobile devices also can be used for watching television programs.


title: Television

text: The television was invented in the 1920s but the equipment was expensive and the pictures were poor. By the 1950s, these problems had been fixed and TVs became widespread.


title: Television

text: At first, all televisions used an antenna (or aerial). This would pick up television programmes from broadcasting stations. A TV station could be many miles or kilometers away, and still be received. TVs can also show movies from VCD and DVD players or VCRs. Cable TV and Satellite television can provide more programs at once than broadcast can. Video game consoles connect to most modern TVs. Some computers can also use a TV as a computer monitor.


title: Television

text: All TVs have screens where the picture is viewed. Before the 1950s these were usually "black and white", which made everything look grey, but all modern TVs show colors. Most 20th century screens also had rounded corners. That is because television screens were cathode ray tubes. These are like heavy glass jars with one side bulging out to form the screen.


title: Television

text: Today flat panel displays are the usual kind. These are usually flat rectangles with straight edges. This long rectangle looks more like the shape of a movie theatre screen. This is called widescreen. If a widescreen set was 30 cm tall, it would be 53 cm wide. For this to work best, TV shows also need to be made in widescreen. Widescreen sets can still be any size, but they have the same widescreen shape.

text: The early 21st century is also when digital television transmission became more common than analog television.


title: Washington, D.C.

text: Washington, D.C. (also known as simply Washington or D.C., and officially as the District of Columbia) is the capital of the United States. It is a federal district. The President of the United States and many major national government offices are in the territory. This makes it the political center of the United States of America.


title: Washington, D.C.

text: Washington was named after the first U.S. President George Washington. "D.C." stands for "District of Columbia". At first, it was made up of a piece from Virginia south of the Potomac River and a piece from Maryland north of the Potomac River. In 1847, Virginia's piece was returned to it, and is now Arlington County and part of the city of Alexandria. Since 1847, all of the District of Columbia is on the north side of the Potomac River. The District of Columbia used to have other small towns which used "D.C.".


title: Washington, D.C.

text: Since 1800, the District of Columbia has been the home of all three branches of the U.S. government: Congress, the President, and the Supreme Court. All of the major political parties are based here. It is also the headquarters of the World Bank, the International Monetary Fund (IMF), and the Organization of American States (OAS). Because it is the home of the President and is important to American politics, many groups often hold large demonstrations and protests here. These are often at the National Mall, a large open park which has many monuments and museums. The District of Columbia’s many museums and monuments make it a popular place for tourists to visit.


title: Washington, D.C.

text: In 2020, the United States Census Bureau said that 689,545 people lived within the District of Columbia.


title: Washington, D.C.

text: When English people first came to the area, there was a Native American village on the spot called "Nakochtank". This name survives in the name of the Anacostia River. This river was known for the healing properties of its pure water and it is recorded that the Emperor Powhatan, who lived in what is now Richmond, Virginia, made the trip all the way to Nakochtank once for this reason.


title: Washington, D.C.

text: The 1789 United States Constitution said that a capital city would be created in a district, but did not say where it should be. James Madison and others thought it should be far away from other states and cities. This way, it would be independent and not controlled by any state. In 1790, a compromise was reached and capital was placed between Virginia and Maryland. It was a square, ten miles (16 km) long on each side, and split by the Potomac River, which separated the two states. Half of the district was in Maryland and the other half was in Virginia, and the two states gave this land to the government. In 1791, it was named "Washington, the District of Columbia" to honor George Washington. "Columbia" was another name for North America. During the War of 1812, the British burned down many government buildings, including the White House.


title: Washington, D.C.

text: Washington, D.C. was planned before it was built. Pierre L'Enfant drew a plan for the city that said where all the streets, parks, and important buildings would be. Unlike most cities in the United States, D.C. has many roundabouts or traffic circles. The city was supposed to have long and wide avenues, and many open spaces for monuments and parks. The National Mall is an example of this.


title: Washington, D.C.

text: Washington, D.C. is not a state. Its citizens have less control over their city than most Americans, but D.C. has had an elected mayor and a city council since 1973. But Congress can make it so that a local law doesn't happen. The current mayor of Washington, D.C. is Muriel Bowser, a Democrat.


title: Washington, D.C.

text: The license plates on the cars in Washington, D.C. say, "Taxation Without Representation." This is a protest from people who live in Washington, D.C. about having to pay taxes to the United States without having a vote in the United States House of Representatives. It resembles the protest made by colonists before the American Revolution about having to pay taxes to Great Britain. Some people are against letting Washington, D.C. have a Congressman or Congresswoman because the Constitution only allows states to have Congressmen or Congresswomen.


title: Washington, D.C.

text: Washington, D.C. is the center of the nation for its arts. The National Symphony Orchestra, the Washington National Opera, and the Washington Ballet are all inside the John F. Kennedy Center for the Performing Arts. The Kennedy Center Honors are given every year to the people who have greatly helped the cultural life of the United States. The President and First Lady usually go to the Honors ceremony.


title: Washington, D.C.

text: As the national capital of the United States, Washington, D.C. has numerous media outlets in various mediums. Some of these media are known throughout the United States, including "The Washington Post" and various broadcasting networks headquartered in D.C.


title: Washington, D.C.

text: "The Washington Post" is the oldest and most-read daily newspaper in Washington, and it has developed into one of the most reputable daily newspapers in the U.S. It is most notable for exposing the Watergate scandal, among other achievements. The Washington Post Company has multiple media holdings, including a daily free newspaper called the "Express", the Washington Post News Service with Bloomberg News, "Fashion Washington", "El Tiempo Latino" (a Spanish-language publication), the Slate Group, "The Daily Herald" (in Washington state), as well as the education company Kaplan, Inc. "The Washington Post" emphasizes national and political news coverage but also covers regional and local stories. Headquartered in downtown Washington, the newspaper employs journalists at 11 regional bureaus in Maryland and Virginia and 14 international bureaus. Content is shared across titles within the Washington Post Company, and the "Express", in particular, often reprints content from the Associated Press, Getty Images, and other wire sources.


title: Washington, D.C.

text: "Washington Times" and "Washington City Paper" also have substantial readership in the District. On February 1, 2005, the free daily tabloid "Washington Examiner" debuted, having been formed from a chain of suburban newspapers known as the "Journal Newspapers".

text: "Washington Blade" and "Metro Weekly" focus on gay issues and the "Washington Sun", the "Washington Informer", and also "Washington Afro" on African American issues. Bi-weekly "Street Sense" focuses on issues of homelessness poverty, and life on the streets. Other special-interest papers include "Roll Call", a daily paper focused on politics.


title: Washington, D.C.

text: Many neighborhoods in the District have their own community newspapers. Some of these include "The Current Newspapers", which has editions serving Dupont Circle, Foggy Bottom, Georgetown, Chevy Chase and Upper Northwest, and a Capitol Hill paper called "The Capitol Hill Current/Voice of the Hill". Additional papers include "In-Towner" (Dupont Circle, Logan Circle and Adams Morgan), "Hill Rag" (Capitol Hill), "East of the River" (Anacostia) and "D.C. North" (Northeast D.C.). In addition, several specialty newspapers serve the U.S. Congress; most notable are "Roll Call", "The Hill", and "Politico".

title: Washington, D.C.

text: According to a 2010 study, Washington-area commuters spent 70 hours a year in traffic delays, which tied with Chicago for having the nation's worst road congestion. However, 37% of Washington-area commuters take public transportation to work, the second-highest rate in the country. An additional 12% of D.C. commuters walked to work, 6% carpooled, and 3% traveled by bicycle in 2010.


title: Washington, D.C.

text: Washington has very few freeways. The funds that had been dedicated for freeway construction were instead redirected to the region's public transportation infrastructure. The interstate highways that do continue into Washington, including Interstate 66 and Interstate 395, both terminate shortly upon entering the city.


title: Washington, D.C.

text: The Washington Metropolitan Area Transit Authority (WMATA) operates the Washington Metro, the city's rapid transit system, as well as Metrobus. Both systems serve the District and its suburbs. Metro opened on March 27, 1976 and presently consists of 86 stations and of track. With an average of about one million trips each weekday, Metro is the second-busiest rapid transit system in the country, after the New York City Subway. Metrobus serves over 400,000 riders each weekday, making it the nation's sixth-largest bus system. The city also operates its own DC Circulator bus system, which connects commercial areas within central Washington.

Major international flights arrive and depart from Washington Dulles International Airport, west of the District in Fairfax and Loudoun counties in Virginia. Dulles gained its own Metrorail station in 2016. Baltimore/Washington International Thurgood Marshall Airport is northeast of the District in Anne Arundel County, Maryland.


title: Great Wall of China

text: The Great Wall of China is an ancient wall in China. The wall is made of cement, rocks, bricks, and dirt. It was finished in 1878 and it was meant to protect the north of the empire of China from enemy attacks. It is the longest structure humans have ever built. It is about 21,196 kilometers long, wide and 15 metres high. The earlier sections on the wall are made of compacted dirt and stone. Later in the Ming Dynasty they used bricks. There are 7,000 watch towers, block houses for soldiers and beacons to send smoke signals.


title: Great Wall of China

text: Nineteen walls have been built that were called the Great Wall of China. The first was built in the 7th century BC. The most famous wall was built between 226–200 BC by the first Emperor of China, Qin Shi Huang (Qin Pronounced as Chin) , during the Qin Dynasty. Not much of this wall remains as people have been stealing from it. It was much farther north than the current wall. The current wall was built during the Ming Dynasty.


title: Great Wall of China

text: Great Wall of Qi was started in 685 BC. The state of Qi made a fortified wall for protection against the Southern states Ju og Lu and later from the kingdom Chu.


title: Great Wall of China

text: Walls on the periphery of the Northern states Yan, Zhao, and Qin became linked together, because all those states came under the rule of emperor Qin Shi Hong, during his rule (221–206 BC).


title: Great Wall of China

text: The First Emperor of China, Qin Shi Huang also called Shi Huangdi, started the Qin Dynasty. The Xiongnu tribes in the north of China were his enemies. The land in some parts of China is easy to cross, so Qin Shi Huang started building the Great Wall to make it more difficult for the Xiongnu to invade China.


title: Great Wall of China

text: Other dynasties in China had worked more on the wall and made it longer. The Han, Sui, Northern and Jin Dynasties all repaired, rebuilt or expanded the Great Wall. During the Ming Dynasty, major rebuilding work took place. Sections of the wall were built with bricks and stone instead of earth. It took more than 2000 years for building and completion of the Great wall.


title: Great Wall of China

text: The Great Wall of China is a series of fortifications that were built across the historical northern borders of ancient Chinese states. It is the longest structure humans have ever built. It is about 21,196 kilometers long, 9.1 metres (30 feet) wide and 15 metres high. It is made over the course of hundreds of years, the wall was built by over 6 different Chinese dynasties, and is over 2,300 years old.


title: Great Wall of China

text: The wall was built to help keep out northern invaders like the Mongols. Smaller walls had been built over the years, but the first Emperor of China, Qin Shi Huang, decided that he wanted a single giant wall to protect his northern borders. The most well-known sections of the wall were built by Ming Dynasty. Genghis Khan, the founder of the Mongol Empire, was the only one who breached the Great Wall of China in its

text: Builders used materials that were nearby. Some parts of the wall were made of mud, straw, and twigs. Thousands of workers died from giant falling stones, exhaustion, disease, animal attacks, and starvation. Workers dying and being buried in and under the Great Wall is a myth.


title: Great Wall of China

text: Rumours about astronauts being able to see the Great Wall from the moon are scientifically not proven. The Great Wall has shown up in radar images taken from space, but scientists are sure it is not possible for astronauts to see the wall with a naked eye. One astronaut who spoke about the visibility of the Great Wall from space was Neil Armstrong. He said that on the moon, it was very clear that the wall was not visible. However, astronaut William Pogue was able to see the wall from a Low Earth Orbit distance (300-530 km height), but only with binoculars and with lots of practice.


title: New York City

text: New York, often called New York City (NYC), is the largest city by population in the United States. It is at the southern end of the state of New York. New York's population is similar to Chicago in Illinois with over 8 million people currently living in it, and over 22 million people live in the bigger New York metropolitan area. It is the financial capital of the U.S. since it is home to the nation's stock market, Wall Street, and the One World Trade Center.


title: New York City

text: Being on one of the world's largest natural harbors, New York City is made up of five boroughs, each of which is a county of the state of New York. The five boroughs—Brooklyn, Queens, Manhattan, the Bronx, and Staten Island—were combined into one city in 1898. The city and its metropolitan area are an important place for legal immigration to the United States. As many as 800 languages are spoken in New York, making it the most linguistically diverse city in the world. New York has more than 3.2 million people born outside the United States, the biggest foreign-born population of any city in the world as of 2016.
