Computer graphics are very useful. Computer-generated imagery is used for movie making, video games, computer program development, photo editing, scientific modeling, design for advertising and more. Some people see computer graphics as art.
Computer graphics can be 2D or 3D. They are made differently and used differently. People can use computer programs to make different types of graphics.
2D computer graphics are usually split into two categories: vector graphics and raster graphics.
Vector graphics use lines, shapes and text to create a more complex image. If a vector graphic image is made very big on the monitor, it will still look as good (smooth) as its regular size. This is one of the reasons vector graphics are liked so much. Vector images also take very little computer memory when saved. Vector graphics are made with programs like Adobe Illustrator and Inkscape, and were used for some older computer games. Today, they are often used for when computer graphics have to be printed out.
Raster images are made up of very small points called pixels. Digital cameras create raster pictures but artists can make them with computers too. The artists don't have to change a single pixel at a time –⁠ raster programs often have tools like paintbrushes, paint buckets and erasers to make a picture. Programs used to make these include Adobe Photoshop, GIMP and Corel Paint Shop Pro.
Sometimes people "do" use only pixels to make an image. This is called pixel art and it has a very unique style.
3D graphics are graphics that look more realistic because they are three-dimensional. This means the computer thinks it has a height, a length and a depth, and displays them as we would see them in the real world with our eyes. Among other things they use solid geometry and trigonometry to create correct perspective. Some programs used to make 3D graphics are Bryce, 3D Studio Max, Maya and Blender. 3D graphics are used many times in movies and TV shows and video games.
Most of 3D graphics can be seen as vector graphics because it uses mathematical shapes like 3D triangles to describe objects. But there also exists 3D graphics that uses a grid of "3D pixels" which we call voxels.
FC Bayern Munich
FC Bayern Munich, also known as FC Bayern München, () is a German football club. The club was founded in 1900 and has over 200,000 paying members. It has won the most titles in the Bundesliga and in the German cup.
The football team is playing in the Allianz Arena. The team also has the most supporters in all of Germany.
Bayern Munich won its first national title in 1932. This was the last season before the Nazi Regime took over the power. Bayern Munich was blamed to be a 'Club of Jews', the president, Kurt Landauer, was forced to flee and several players were punished. After the war ended, erroneously the local rival "1860 München" was considered to be better and let into the first German league. But in the first season 1963, Bayern Munich won most of its games, ascended into the first league and still plays there without any descend.
Bayern Munich won the UEFA Champions League in 2001 and in 2013. 2013 also was the year of the victory of the historic treble - an achievement no other German club ever gained before.

The Cape of Good Hope is a place near the far south end of Africa, where the Atlantic Ocean and the Indian Ocean meet. It is a well known area for ships that pass in the sea between southern Africa and Antarctica. It is in the Western Cape Province of South Africa and forms part of the Table Mountain National Reserve.
The first person from Europe to see it was the Portuguese man Bartolomeu Dias. He saw it in 1488 and named it the "Cape of Storms".
Hand washing
Hand washing is the process of cleaning hands with water and soap or other special liquids. It is done to take off dirt, germs, and poisons. Germs and poisons cause diseases and other health problems. Germs are bacteria, viruses, or fungi. Some diseases are not stopped by antibiotic drugs. Hand washing prevents lots of new diseases. Not washing hands before cooking or touching food is risky.
Always wash hands:
Use soap and warm (running, if available) water. Wet hands and add soap. Rub wet hands strongly with soap outside running water more than 10 seconds. Rub all parts of the hands again and again. Clean all dirt under fingernails. Then rub hands under running water again and again to take off all soap. Dry hands using a clean cloth or paper. Use moisturizing lotion so hands do not dry if the hands are being washed many times every day.
For a medical worker, doctor, or nurse, not washing hands before touching every new person is dangerous. Use more than enough soap and water and rub each part of the hands again and again. Rub between each finger. Use a brush and clean under fingernails. Use more water to take off the soap and dry hands paper towel.
To "scrub" the hands for a surgery, water that can be turned on and off without touching with the hands is needed, a cleaning liquid named "chlorhexidine" or "iodine wash", sterile cloth for drying the hands after washing, a sterile brush for hard washing and another sterile instrument for cleaning under the fingernails. Take off all watches, rings, and other jewels from the hands before washing. Wash the hands and arms to the elbows again and again. Be strong and serious about the washing. Use running water again and again to take off all soap. Keep hands up so water does not go from arms to hands. Dry the hands with the sterile cloth and put on surgical shirt or dress. Sterile means nothing on it that could cause a disease.
Franklin Delano Roosevelt (January 30, 1882 - April 12, 1945) was the 32nd President of the United States from 1933 until his death in 1945. He served 12 years as President, dying shortly after beginning his 4th term, the longest ever spent in office. After his death, the 22nd Amendment came into effect, limiting how long a person could be President. Before becoming President, he was Governor of New York from 1929 to 1932, Assistant United States Secretary of the Navy from 1913 to 1920 and a state senator from the state of New York.
His father James Roosevelt and his mother Sara Delano were from rich old New York families that made money from slavery. The Roosevelts were originally Dutch, and the Delanos were originally French. Franklin was their only child. His father's grandmother, Mary Rebecca Aspinwall, was a first cousin of Elizabeth Monroe, wife of the fifth U.S. President, James Monroe.
One of his ancestors was John Lothropp, also an ancestor of Benedict Arnold and Joseph Smith, Jr. One of his distant relatives from his mother's side is the author Laura Ingalls Wilder. His maternal grandfather Warren Delano II, a descendant of "Mayflower" passengers Richard Warren, Isaac Allerton, Degory Priest, and Francis Cooke, during a period of twelve years in China made more than a million dollars in the tea trade in Macau, Canton, and Hong Kong, but upon coming back to the United States, he lost it all in the Panic of 1857.
In 1860, he came back to China and made a fortune in the notorious but highly profitable opium trade supplying opium-based medication to the U. S. War Department during the American Civil War. He is a 5th cousin and a nephew-in-law of another United States President Theodore Roosevelt. His 5th cousin, once removed was Eleanor Roosevelt, who was also his widow. Roosevelt once had an affair with his wife's secretary and later avoided seeing her to protect his political career.
Franklin Delano Roosevelt was born on January 30, 1882 in the Hudson Valley town of Hyde Park, New York. When Roosevelt was five years old his father took him to visit President Grover Cleveland. The president said to him: "My little man, I am making a strange wish for you. It is that you may never be President of the United States." Roosevelt became the longest-serving president in American history.
Roosevelt was the Assistant of the United States Secretary of the Navy under Woodrow Wilson. He was nominated the vice presidential candidate under James M. Cox in 1920. Cox and Roosevelt lost to Warren Harding and Calvin Coolidge.
In 1921, Roosevelt got sick with poliomyelitis, a disease that paralyzes people. He never walked again, but Roosevelt remained physically fit, becoming an avid swimmer. Roosevelt became a champion of medical research and treatment for crippling illnesses, but kept his illness as hidden as much as possible from the public, fearing discrimination. His disability did not limit his political career; Roosevelt was elected the Governor of New York in 1928. His wife, Eleanor Roosevelt helped his career by traveling and meeting people when Roosevelt could not. She became famous as his eyes and ears, meeting thousands of ordinary people and bringing their concerns to Roosevelt.
Roosevelt won the election against the unpopular incumbent (president at the time) Herbert Hoover and became president in early 1933.
He started a series of popular programs known as the New Deal to fight against the Great Depression. The New Deal gave people jobs building roads, bridges, dams, parks, schools, and other public services. Also, it created Social Security, made banks insure their customers, gave direct aid to the needy, and made many regulations to the economy. Because of this, he was re-elected in a large victory in 1936 and continued the New Deal. The United States did not fully recover from the Great Depression until it entered World War II.
In 1939, Roosevelt became the first President of the United States to appear on television. Roosevelt was elected a third term in 1940. He gave weapons and money to the Allies fighting in World War II as a part of the Lend-Lease program at this time, but the United States was still technically neutral in the war.
On December 7, 1941, Japan launched its attack on the Pearl Harbor military base in Hawaii. On December 8, the United States Congress declared war on the Empire of Japan. It was formulated an hour after the famous Infamy Speech by Roosevelt. After the declaration, Japan's allies, Germany and Italy, declared war on the United States. This brought the United States fully into World War II.
The military used a draft to get people to fight the war, but many people in Puerto Rico, a colony of the United States, did not want to fight because they felt the U.S. was treating them badly by occupying the island. The U.S. forced them to fight and to help pay for war supplies anyway.
Roosevelt also signed an order allowing Japanese Americans to be sent to internment camps against their will. While still president, he died on April 12, 1945. Vice President Harry Truman became president. World War II continued for almost four more months, but Allied victory was already assured.
For overcoming the difficult challenges of a depression and a world war, historians generally consider him to be one of the best U.S. presidents.
Venezuela is a country in northern South America. Its official name is República Bolivariana de Venezuela (Bolivarian Republic of Venezuela). The official language is Spanish, and the capital is Caracas.
The country has a wide range of geography including islands in the Caribbean Sea, coastal areas, highlands, and parts of the Andes Mountains. Venezuela is famous for being the home of Angel Falls, the world's tallest waterfall, in the Bolivar state.
Venezuela produces a large amount of oil every year, and it has one of the largest oil supplies in the world. The country has a very large supply of fossil fuels, gasoline, and minerals. Venezuela's economy is based on oil, cotton, cocoa, sugar, coffee, and tobacco.
Some other languages spoken in Venezuela are Carib, Guahibo, Warao, Wayuu, Pemon, and Piaroa. Most people are Roman Catholic at 96%, and a small minority is Protestant at 2%.
Ancient Venezuelans came from the east, west, south, and north. Christopher Columbus was the first European to enter Venezuela, but there were already people living there for a long time. The Spaniards first conquered Venezuela. Slaves were imported from Africa.
Venezuela's inhabitants are very racially mixed. This comes from the colonial period. When whites (the British, Spaniards, French, etc.) conquered America's territory, they took their black African slaves to America to work. During Venezuela's colonial time, black people did not have any rights. They just worked for food. The native people were taught Roman Catholicism. For a long time, society was headed by white creoles, people in Venezuela that were descended from Spaniards but considered Venezuela home. The other Venezuelan people did not like that, and they started thinking about independence. On July 24, 1823, Venezuela won its independence, led by Simón Bolívar.
Venezuela's modern history was shaped by a number of people, including President Romulo Betancourt, who replaced a military dictatorship with a democracy. By the 1970s, Venezuela had become rich off of oil revenue, but it had problems in the 1980s and 1990s. In 1999 Hugo Chávez became president and tried to remake Venezuela as a socialist state. While popular at first, the economic changes Chavez and the next president, Maduro, passed caused a massive economic depression in the mid 2010s. The current president is disputed.
The population of Venezuela is about 28,000,000 people. The ethnic groups of the population are:
Saudi Arabia officially known as the Kingdom of Saudi Arabia , is a country in Western Asia including most of the Arabian Peninsula. The land area is approximately , so Saudi Arabia is geographically the 5th-largest state in Asia and 2nd-largest state in the Arab world after Algeria. Saudi Arabia is bordered by Jordan and Iraq to the north, Kuwait to the northeast, Qatar, Bahrain, and the United Arab Emirates to the east, Oman to the southeast, and Yemen to the south. It is separated from Israel and Egypt by the Gulf of Aqaba. It is the only nation with both a Red Sea coast and a Persian Gulf coast, and most of its land is dry and barren. Saudi Arabia is the birthplace of Arabs and Islam and sometimes called "the Land of the Two Holy Mosques" in reference to Al-Masjid al-Haram (in Mecca), and Al-Masjid an-Nabawi (in Medina), the two holiest places in Islam. Arabic is the exclusive official language in Saudi Arabia.
Sunni Islam is the state religion. The practice of non-Islamic religions is forbidden in public but not in private. The Hanbali school of faith has a big influence, and the ultra-conservative Wahhabism religious movement within Sunni Islam has been called "the predominant feature of Saudi culture".
Saudi Arabia is the largest state in western Asia by land area (most of the Arabian Peninsula) and the second-largest in the Arab World. It has an estimated population of 27 million, of which 8.8 million are registered foreign expatriates and an estimated 1.5 million are illegal immigrants. Saudi nationals comprise an estimated 16 million people.
Saudi Arabia has the world's largest petroleum reserves and is the world's largest oil exporter. Oil accounts for more than 90% of exports and nearly 75% of government revenues, facilitating the creation of a welfare state. However, human rights groups such as Amnesty International and Human Rights Watch have expressed concern about the state of human rights in Saudi Arabia.
Saudi Arabia has cities that are important to the Muslim religion. Many Muslims from around the world visit Mecca in Saudi Arabia to make a pilgrimage. The pilgrimage is one of the "pillars of Islam". Other big cities are Riyadh, Jeddah and Dammam. The pilgrimage is called hajj in the Arabic language. Somebody who makes a pilgrimage to Mecca is called a "hajj" in the Arabic language. People who are not Muslim are not allowed to enter Mecca.
Most people speak the Arabic language.
The currency of Saudi Arabia is referred to as the Saudi Riyal.
The area of modern-day Saudi Arabia formerly consisted of four distinct regions: Hejaz, Najd, and parts of Eastern Arabia (Al-Ahsa) and Southern Arabia ('Asir). The Kingdom of Saudi Arabia was founded in 1932 by Ibn Saud. He united the four regions into a single state through a series of conquests beginning in 1902 with the capture of Riyadh, the ancestral home of his family, the House of Saud. The country has since been an absolute monarchy, governed along Islamic lines.
The Kingdom of Saudi Arabia was founded by Abdul-Aziz bin Saud (known for most of his career as "Ibn Saud") in 1932. The conquests which eventually led to the creation of the Kingdom began in 1902 when he captured Riyadh, the ancestral home of his family, the House of Saud. The Saudi Arabian government, which is an absolute monarchy, refers to its system of government as being Islamic. It has a strong basis in Wahhabism, a minority school of thought in Islam. The kingdom is sometimes called "The Land of the Two Holy Mosques" in reference to Masjid al-Haram (in Mecca), and Masjid al-Nabawi (in Medina), the two holiest places in Islam.
Saudi Arabia is an absolute monarchy. However, according to the Basic Law of Saudi Arabia adopted by royal decree in 1992, the king must comply with Sharia (Islamic law) and the Quran, while the Quran and the Sunnah (the traditions of Muhammad) are declared to be the country's constitution. The primary source of law is the Islamic Sharia derived from the teachings of the Qur'an and the Sunnah (the traditions of the Prophet). Saudi Arabia is unique among modern Muslim states in that Sharia is not codified and there is no system of judicial precedent, giving judges the power to use independent legal reasoning to make a decision. Saudi judges tend to follow the principles of the Hanbali school of jurisprudence (or "fiqh") found in pre-modern texts and noted for its literalist interpretation of the Qur'an and hadith.
Because the judge is empowered to disregard previous judgments (either his own or of other judges) and may apply his personal interpretation of Sharia to any particular case, divergent judgements arise even in apparently identical cases, making predictability of legal interpretation difficult. The Sharia court system constitutes the basic judiciary of Saudi Arabia and its judges (qadi) and lawyers form part of the ulema, the country's Islamic scholars.
Royal decrees are the other main source of law; but are referred to as "regulations" rather than "laws" because they are subordinate to the Sharia. Royal decrees supplement Sharia in areas such as labor, commercial and corporate law. Additionally, traditional tribal law and custom remain significant. Extra-Sharia government tribunals usually handle disputes relating to specific royal decrees. Final appeal from both Sharia courts and government tribunals is to the King and all courts and tribunals follow Sharia rules of evidence and procedure.
A hijab is a traditional Islamic norm whereby women are required "to draw their outer garments around them (when they go out or are among men)" and dress in a modest manner. Saudi Arabia is different from many Islamic societies in the extent of the covering that it considers Islamically correct hijab (everything except the hands and eyes) and the fact that covering is enforced by "Mutaween" or religious police.
Among unrelated men, women must cover the parts of the body that are awrah (private). In much of Islam, a women's face is not considered awrah. In Saudi Arabia and some other Arab states, all of the body is considered awrah except the hands and eyes. Accordingly, most women are expected to wear the hijab (head covering), a full black cloak called an abaya, and a face-veil called niqab. Many historians and Islamic scholars argue that the Quran was interpreted to require the veil as part of adapting it to tribal traditions.
Saudi Arabia is home to the largest mass of sand on earth, known as the Rub-al Khali desert (Rub-al Khali means "empty quarter"). The temperature is very hot. There are almost no rivers or lakes in the country. There are many wadis.
The countries of Yemen and Oman are south of Saudi Arabia. Saudi Arabia is west of Qatar, the United Arab Emirates, Kuwait, Iraq, and Jordan. All of these countries, except Jordan and Iraq, make the Arabian Peninsula.
Animal life includes wolves, hyenas, mongooses, baboons, hares, sand rats, and jerboas. There used to be many larger animals such as gazelles, oryx, and leopards. By the 1950s hunting from motor vehicles made these animals almost extinct. Birds include falcons (which are caught and trained for hunting), eagles, hawks, vultures, sand grouse and bulbuls. There are several species of snakes, many of which are venomous, and numerous types of lizards. There is a wide variety of marine life in the Persian Gulf. Domesticated animals include camels, sheep, goats, donkeys, and chickens.
Because it is mostly a desert Saudi Arabia’s plant life is mostly small herbs and shrubs that need little water. There are a few small areas of grass and trees in southern Asir. The date palm ("Phoenix dactylifera") is widespread.
Saudi Arabia is divided into 13 provinces. The provinces are divided into 118 governorates.
These are the largest cities in Saudi Arabia.
Colombia (; ), officially the Republic of Colombia, is a tropical equatorial country in northern South America. It is in the northwest part of the continent, and it has an area of 1,141,748 km² (440,839 sq mi).
It is the only South American country with coasts on the Pacific Ocean and the Caribbean Sea.
The countries that have borders on the continent with Colombia are: Venezuela (east), Brazil (southeast), Peru (south), Ecuador (southwest) and Panama (west). The countries that have borders with Colombia on the sea are: Nicaragua, Panama, Costa Rica, Guatemala, Honduras, Jamaica, Haiti and Dominican Republic.
More than 50 million people live in Colombia. It is the third most populated country in Latin America after Mexico and Brazil.
The capital of Colombia is Bogotá. The second city is Medellín, a large industrial center. The third largest city is Cali, home to many multinational companies. The most important city of the country on the Caribbean coast is Barranquilla. It was also the first national port. Cartagena de Indias has a great Spanish wall from the 17th Century and an old town with 500-year-old buildings. After these cities comes Bucaramanga, a large city near the Venezuelan border, and the center of the textile industry in Colombia.
The word ""Colombia"" is named after Christopher Columbus, the explorer who began the European colonization of the Americas.
In 1819, Colombia, Venezuela, Ecuador and Panama declared independence from Spain, and formed a country called ""Gran Colombia"". Venezuela and Ecuador separated in 1830. Panama continued to be part of Colombia until 1903, at which point it proclaimed independence. The official language is Spanish, but there are many languages spoken by minorities and official in theirs jurisdiction.
The land where Colombia now stands has been home to people for more than 20,000 years. The first people had many groups, cultures, and languages. There are many tools, caves, and things of those peoples. In Colombia, the peoples were similar to those of Asia, because scientists say that the first people came to America from Siberia or southeast Asia more than 50,000 years ago. The peoples of Colombia were called Arawak, Caribe, and Chibcha, but there were many other groups. The most famous were the Muiscas. legend of El Dorado comes from the Muiscas. The king of the Muiscas used to bathe in Lake Guatavita and he used a lot of gold for his bath. The Spanish heard about this, and the people told them that there was a great golden city somewhere. They started to look for El Dorado. The International Airport of Bogotá is called El Dorado International Airport, because the legend was born in Colombia. The descendants of the first peoples of Colombia live integrated with others. Some groups live in the forest, but many live in the countryside and in the cities.
The Spanish, led by Christopher Columbus, first came to the Americas in 1492. Columbus saw the coasts of Venezuela, Colombia and Panama and he gave them his own name. But Alonso de Ojeda was the first colonist to explore the area of the Gulf of Darién. After that, the Spanish founded the first European cities on the American continent: Santa Marta in 1525 and Cartagena de Indias in 1533. It was from Colombia that the Spanish conquered the Incas of Peru.
Spain would enslave the indigenous peoples who were already living there, but they also used the port they built at Cartagena to bring many black slaves from Africa into the area. The Spanish captured many, many people from Africa and forced them to work on plantations and ranches, in mines, and as personal servants.
While this was happening, they founded the city of Popayán in 1536 and they conquered the "Confederation of the Muiscas". In Bacatá, the capital of the Muiscas, the Spanish founded the city of Santa Fe in 1538. In 1550 the Spanish declared the territory as a colony and its capital was "Santa Fe de Bogotá", but in the first decades it depended on Peru. Soon after, it was declared a Viceroyalty.
On November 11, 1810, the city of Cartagena de Indias declared its independence from Spain. The whole region would fight a war to become independent, led by people like Antonio Nariño and Simón Bolívar. Nariño was one of the most important leaders in the war for the independence of Colombia. He was a politician, journalist and soldier. Bolivar was another important leader, and he was a president and a colonel. Bolivar had promised Alexandre Pétion, the president of Haiti, that he would abolish slavery during his independence war. But he only agreed because he was afraid the slaves would revolt against the slaveowners, like they did in Haiti, and only freed slaves if they agreed to fight in his army. He never freed all the slaves, and slavery was not abolished in Colombia until 1851.
The geography of Colombia has six main natural regions. Each has its own unique characteristics. The Andes mountain region shares borders with Ecuador and Venezuela. The Pacific Coast region shares borders with Panama and Ecuador. The Caribbean coastal region shares borders with Venezuela and Panama. The "Llanos" (plains) shares a border with Venezuela. The Amazon Rainforest region shares a border with Venezuela, Brazil, Peru and Ecuador. The insular region includes all the islands of the country.
The main rivers of Colombia are Magdalena, Cauca, Guaviare, Atrato, Meta, Putumayo and Caquetá. Colombia has four main drainage systems: the Pacific drain, the Caribbean drain, the Orinoco Basin and the Amazon Basin.
Most of the population lives in the Andes region. But the plains make over half the land. Only about 6% of the people live in the plains. The Sierra Nevada de Santa Marta mountain range includes the country's tallest peaks (Pico Cristóbal Colón and Pico Simón Bolívar).
Colombia's temperature changes with the altitude, and the temperature is different by region. The regions around the Andes are colder than the coast, which is lower.
Because of the many altitudes, Colombia has many different fruits, vegetables and kinds of animals. It has many valleys, beaches, plains, mountains and forests like the Amazon rainforest.
The top of some of the mountains in Colombia are so cold that people can ski over the equator. The lower mountains have warmer climates. The sea shores are cooled by ocean breezes. At sea level near the equator it is hot.
Rivers are important as waterways in the land for shipping things. One of the most important rivers in Colombia is the Magdalena-Cauca. The Magdelena River divides the eastern and center mountains. It makes a fertile valley. The Cauca River divides the center mountain range and the western ridge, making another great valley. The Cauca is really a part of the Magdalena. However, the two do not meet until a few miles before the Magdalena goes into the Caribbean Sea.
Colombia is a megadiverse country. This means the country is home to a majority of Earth's species. There are also a high number of endemic species.
Colombia has 1,900 species of bird, more than any other country. There are about 2,000 species of marine fish. It is the second most diverse country in freshwater fish. As for plants, the country has between 40,000 and 45,000 species. Colombia is second in the number of amphibian species and is the third most diverse country in reptiles. There are about 2,900 species of mollusks and about 300,000 species of invertebrates.
In May 2006, President Álvaro Uribe was re-elected. His term lasted until 2010. Uribe was the first President in Colombia to win a second election in over 100 years.
In August 2010, Juan Manuel Santos became Colombia's president. Santos won the election on June 20 by a landslide. He promised to "preside over a government of national unity that will bring social prosperity for all Colombians"
Eight years later, conservative Senator Iván Duque Márquez was elected President and soon became the nation's latest president. He won the election by 2 million votes against his rival liberal Senator Gustavo Petro.
Colombia is divided into 32 departments and one capital district. The capital district is treated as a department. Departments are divided into municipalities. Municipalities are divided into "corregimientos". Each department has a local government with a governor and assembly directly elected to four-year terms. Each municipality is headed by a mayor and council. Each "corregimiento" by an elected "corregidor", or local leader.
The population of Colombia was approximately 47 million as of 2016. The ethnic groups of the population are:
Up to 49.6% of the population is living below the poverty line.
There are several guerilla groups in Colombia, the FARC being the most powerful, a guerilla group responsible for kidnappings, murders, attacks, and drug-dealing. Drug dealing is a problem the government has been trying to fight. This creates violence in the cities. With Operation: Jaque, Ingrid Betancourt, three Americans, and 11 soldiers were rescued from the FARC.
Most parts of Colombia are modern and the country has many roads. All major Colombian cities have airports and there are many ports on both oceans (Pacific and Atlantic). Because Colombia is a huge country and there are many mountains, airports are very important in the country. There are some regions like the Amazon Forest and Dariend, where the most important way of transportation is by the rivers.
Colombia also has some very well known cities.
Colombia has made many advances in medicine. Many foreigners come to the country to get health services, such as organ transplants or plastic surgery. Doctor Manuel Elkin Patarroyo of Colombia discovered a medicine against malaria. He donated his discovery to be used in Africa and Latin America. He did not want to make business of it, instead he wanted to use it to help people.
Colombia is known for its coffee, coal, and emeralds. It is also the biggest supplier of plantains to the United States. There are a few armed conflicts in Colombia. Most rebel groups finance their operations with the trade of illegal drugs (mostly cocaine).
Abel Tasman
Abel Janszoon Tasman (1603–1659) was a Dutch sea explorer. He found Tasmania and New Zealand while on voyages in 1642 and 1644, in the service of the VOC (Dutch East India Company). He also made the first historical sightings of large parts of Australia.
He was born in Groningen, Holland. He went to Batavia (now called Jakarta) to work for the VOC in 1633. He went back to Holland in 1636. He went back to Batavia with his wife, Jannetie Tjaerss, two years later. He went north to Japan in 1640. In 1642 Tasman went south to Palembang.
Tasman set Governor General of the Dutch East Indies. Tasman sailed around to the east coast of Van Diemen's Land and claimed the land for the Dutch on December 3, 1642. The ships then sailed west and found New Zealand. His ships were attacked by Maori in large war canoes (boats) and four sailors died. Tasman then sailed north-east to Tonga and Fiji. He then sailed north west to New Guinea and got back to Batavia in June 1643.
In 1644 Tasman sailed from Batavia with the ships "Limmen", "Zeemeeuw" and "Bracq". He sailed along the west coast of New Guinea, and then the coast of Australia from Cape York to North West Cape. He went back to Batavia in August 1644. He showed that Western Australia and Queensland were part of the same country. He was not able to get through Torres Strait, but his maps were used for the next 200 years. Tasman made more trips including to Sumatra in 1646, Siam in 1647, and Manila in 1648. He purchased a lot of land in Batavia where he died in October 1659.
Several places have been named after him, including Tasmania, the Tasman Peninsula, Tasman Island and the Tasman Sea.
Hard science
Hard science is science that uses systematic observation, experiments and sometimes mathematics to get knowledge. In hard science, experiments have to be reproducible (if the experiment is done a second time, it will have to produce the same results as the first time). Also, in hard sciences there is usually good agreement as to what is known for sure. This is not true of soft sciences. Also, in hard science there is a world-view or theory which is widely agreed.
Hard science subjects include the natural sciences, which are about the natural world. These include physics, chemistry, biology, geology, astronomy, and botany. Soft science is any of the social sciences, including history, sociology, and political science. Those sciences are soft because something could be done more than once, and produce a very different result each time. Also, there are radical disagreements between various schools of thought. Some aspects of psychology are hard science, especially relating to perception.
Artificial intelligence (AI) is the ability of a computer program or a machine to think and learn. It is also a field of study which tries to make computers "smart". They work on their own without being encoded with commands. John McCarthy came up with the name "Artificial Intelligence" in 1955.
In general use, the term "artificial intelligence" means a programme which mimics human cognition. At least some of the things we associate with other minds, such as learning and problem solving can be done by computers, though not in the same way as we do. Andreas Kaplan and Michael Haenlein define AI as a system’s ability to correctly interpret external data, to learn from such data, and to use those learnings to achieve specific goals and tasks through flexible adaptation.
An ideal (perfect) intelligent machine is a flexible agent which perceives its environment and takes actions to maximize its chance of success at some goal or objective. As machines become increasingly capable, mental faculties once thought to require intelligence are removed from the definition. For example, optical character recognition is no longer perceived as an example of "artificial intelligence": it is just a routine technology.
At present we use the term AI for successfully understanding human speech, competing at a high level in strategic game systems (such as Chess and Go), self-driving cars, and interpreting complex data. Some people also consider AI a danger to humanity if it continues to progress at its current pace.
An extreme goal of AI research is to create computer programs that can learn, solve problems, and think logically. In practice, however, most applications have picked on problems which computers can do well. Searching data bases and doing calculations are things computers do better than people. On the other hand, "perceiving its environment" in any real sense is way beyond present-day computing.
AI involves many different fields like computer science, mathematics, linguistics, psychology, neuroscience, and philosophy. Eventually researchers hope to create a "general artificial intelligence" which can solve many problems instead of focusing on just one. Researchers are also trying to create creative and emotional AI which can possibly empathize or create art. Many approaches and tools have been tried.
Borrowing from the management literature, Kaplan and Haenlein classify artificial intelligence into three different types of AI systems: analytical, human-inspired, and humanized artificial intelligence. Analytical AI has only characteristics consistent with cognitive intelligence generating cognitive representation of the world and using learning based on past experience to inform future decisions. Human-inspired AI has elements from cognitive as well as emotional intelligence, understanding, in addition to cognitive elements, also human emotions considering them in their decision making. Humanized AI shows characteristics of all types of competencies (i.e., cognitive, emotional, and social intelligence), able to be self-conscious and self-aware in interactions with others.
Humanoid robots were built by Yan Shi, Hero of Alexandria, and Al-Jazari. Sentient machines became popular in fiction during the 19th and 20th centuries with the stories of "Frankenstein" and "Rossum's Universal Robots".
Formal logic was developed by ancient Greek philosophers and mathematicians. This study of logic produced the idea of a computer in the 19th and 20th centuries. Mathematician Alan Turing's theory of computation said that any mathematical problem could be solved by processing 1's and 0's. Advances in neurology, information theory, and cybernetics convinced a small group of researchers that an electronic brain was possible.
AI research really started with a conference at Dartmouth College in 1956. It was a month-long brainstorming session attended by many people with interests in AI. At the conference they wrote programs that were amazing at the time, beating people at checkers or solving word problems. The Department of Defense started giving a lot of money to AI research and labs were created all over the world.
Unfortunately, researchers really underestimated just how hard some problems were. The tools they had used still did not give computers things like emotions or common sense. Mathematician James Lighthill wrote a report on AI saying that "in no part of the field have discoveries made so far produced the major impact that was then promised". The U.S and British governments wanted to fund more productive projects. Funding for AI research was cut, starting an "AI winter" where little research was done.
AI research revived in the 1980s because of the popularity of expert systems, which simulated the knowledge of a human expert. By 1985, 1 billion dollars were spent on AI. New, faster computers convinced U.S. and British governments to start funding AI research again. However, the market for Lisp machines collapsed in 1987, and funding was pulled again, starting an even longer AI winter.
AI revived again in the 90s and early 2000s with its use in data mining and medical diagnosis. This was possible because of faster computers and focusing on solving more specific problems. In 1997, Deep Blue became the first computer program to beat chess world champion Garry Kasparov. Faster computers, advances in deep learning, and access to more data have made AI popular throughout the world. In 2011 IBM Watson beat the top two Jeopardy! players Brad Rutter and Ken Jennings, and in 2016 Google's AlphaGo beat top Go player Lee Sedol 4 out of 5 times.
What is Artificial Intelligence (A.I)?
A computer programmer is a person who makes computer programs using a programming language. Programmers are also called software developers, coders, or hackers.
A programmer's main jobs are writing program source code, testing if it works, and debugging (fixing) the program if there are problems. Programmers often use software tools such as text editors and IDEs (Integrated Development Environments) to help them work.
Computer programming is a profession that can be done from a computer anywhere in the world. This is called "telecommuting" - doing work on the Internet instead of in an office.
Some programmers are famous because their software is used by many people. One example is Linus Torvalds, who created an important part of the Linux operating system.
Programming can be done in many different languages and can look very different but do the same thing. An example of this is the Hello world program.
A programming language is a type of written language that tells computers what to do. Examples are: Python, Ruby, Java, JavaScript, C, C++, and C#. HTML is a markup language, in a technical sense not a programming language, since a program can't be made with it, while it still does tell the computer, i.e. web browser, what information to display. Neither is CSS, these languages are used to make web pages, they can be used to make static web pages, while often one or more programming languages are used additionally to make a dynamic web page. Neither are notebook environments programming languages (while often used by programmers), such one of the more popular ones, Jupyter, that is made for many programming languages, such as Julia, Python, and R (most often users choose to use only one programming language with it, one of those three officially supported and the project named after, or some other language). Programming languages are used to write all computer programs and computer software. A programming language is like a set of instructions that the computer follows to do something.
A programmer writes text in the source code of a programming language to make programs. Usually, the programming language uses real words for some of the commands (e.g. "if... then... else...", "and", "or"), so that the language is easier for a human to understand. Like any normal language, many programming languages use punctuation. Many programs are then compiled, which means that the computer changes, or translates, the source code into another language (such as assembly language or machine language) that a computer can read, but which is much harder for a person to read.
Computer programs must be written very carefully. If a programmer makes mistakes, or a program tries to do something the programmer did not design it to do, then the program might then stop working, which is called "crashing". When a program has a problem because of how the code was written, this is called a "bug". A very small mistake can cause a very big problem.
There are many types of programming languages. Most programming languages do not follow one type alone, so it is difficult to assign a type for each language. The examples of each type are given in each section below because they are the best well-known examples of that type.
High-level programming languages require less knowledge about the hardware compared to low-level programming languages. This is because high-level programming languages abstract away the hardware the program is running on. Many high-level languages require an interpreter to run the source code on the hardware in real time. On the other hand, low-level languages usually convert the whole source code to machine code before running, because the source code is so close to the hardware that it is easy to do so.
"Declarative" programming languages describe a "problem" but they usually do not say how the problem should be solved. The problem description uses logic, and "solving" the problem often looks like automatically proving a system of logical axioms. Examples for such programming languages are Prolog, XSLT, LISP and SQL.
"Imperative" programming languages describe a system of state changes. At the start, the program is in a certain "state", and the computer is given steps to follow, in order to perform an action. Following the steps causes the program to "change state".
In general, declarative programming languages are safer and shorter. Imperative programming languages are more common, because they are easier to use.
Functional programming looks at programming like a function in mathematics. The program receives "input", together with some information, and uses this information to create "output". It will not have a state in between, and it will also not change things that are not related to the computation.
Procedural programs specify or describe sets of steps or state changes.
Stack based languages look at some of the program's memory like a stack of cards. There are very few things that can be done with a stack. A data item can be put on the top of the stack. This operation is generally called "push". A data item can be removed from the top of the stack. This is called a "pop". You can look at the item at the top of the stack without removing it. This is called a "peek".
If a program is written as "push 5; push 3; add; pop;" it will put 5 on the top of the stack, put 3 on top of the 5, add the top two values (3 + 5 = 8), replace the 3 and 5 with the 8, and print the top (8). Examples for programming languages that are stack-based are the languages Postscript and Forth.
Object-oriented programming languages place data and "functions" that change data into a single unit. This unit is called an "object". Objects can interact with each other and change another object's data. This is usually called encapsulation or information hiding. Most modern programming languages are object-oriented, or at least allow this style of programming. Examples of this are Java, Python, Ruby, C++, C# and other C languages.
Flow oriented programming sees programming as connecting different components. These components send messages back and forth. A single component can be part of different "programs", without the need to be changed internally.
Some of the languages above can be used for scientific computing. For example, C++ and Python are also used in this way. On the other hand, there are some languages that has scientific computing as their main purpose. The following are some examples:
LaTeX and SATySFi are programming languages which helps document creation.
Every programming language has rules about what it can and can not do. These include:
Most languages have official standards that define the rules of how to write the source code. Some programming languages have two or more standards. This can happen when a new standard replaces an old one. For example, the Perl 5 standard replaced Perl 4 in 1993. It can happen because two people made two standards at the same time. For example, there are several standards for APL.
Object-Oriented Programming (sometimes shortened to OOP) is a form of programming where all parts of the program are objects. Objects are pieces of memory with the same structure that can be used again and again. A bank account, bitmap, or hero from a video game could all be objects within a program. Objects are made up of properties (pieces of information the object stores) and methods which are things the object can do. A Dog object might have properties like height and hairColor. Its methods might include bark() and wagTail().
All objects are created from templates called classes. You can think of a class as a mold from which objects are made. The class defines all the properties and methods that its objects will have. Objects created from a class are called instances of the class. A class can "extend" another class, which means that it takes all the properties and methods of the class but can add its own.
Here is an example of what a class might look like in a programming language:
Notice that the Dog class extends the Mammal class, so all dogs will have the properties of a mammal, like hairLength, and methods, like eat() or sleep().
Object-oriented programming is used in many of today's most popular programming languages, such as Java, C#, Objective-C, C++, Python, Ruby, Javascript, and ActionScript.
Here is a simple program written in Visual Basic (a language made by Microsoft):
This program asks the user his or her age and responds based on what the user typed. If the user typed something that is not a number, the program says so. If the user typed a number less than zero, the program says so. If the user says he or she is older than 100 years old, the program says "That's old!" If the user typed a correct age the program says back to the user how old he or she is.
Here is a program that does the same thing as the program above, but in Python:
The same thing as the program above, but in C#:
public class Hello
The same thing again, but in Haskell:
import Text.Read
main = do
Visual Basic (VB) is a programming language developed by Microsoft for their operating system Windows. The BASIC language is said to be easier to read than other languages.
