Lasker won first prizes at very strong tournaments in St. Petersburg 1895–1896, Nuremberg 1896, London 1899, Paris 1900. As time passed, there arose two great players, Akiba Rubinstein and Capablanca. Both deserved a match for the world championship, but as it turned out, the chance came to another fine player, Carl Schlechter.

Lasker arranged the World Chess Championship match against Schlechter in January–February 1910. Schlechter was a modest man, who was generally unlikely to win the major chess tournaments by his peaceful inclination, his lack of aggressiveness and his willingness to accept most draw offers from his opponents (about 80% of his games finished by a draw).p404
The conditions of the match are still debatable, because they were never published.p357 Some claim that Schlechter accepted especially unfavourable conditions. Giffard says he would need to finish two points ahead of Lasker to be declared the winner of the match, and he would need to win a revenge match to be declared World Champion.p404 This opinion is not proven.

The match was originally meant to consist of 30 games, but when it became obvious that there were insufficient funds (Lasker demanded a fee of 1,000 marks per game played), the number of games was reduced to ten.

In the fifth game Lasker had a big advantage, but made a mistake which cost him the game. Schlechter was now a point ahead. The score before the last game was 5–4 for Schlechter. In the tenth game Schlechter tried to win and took a clear advantage, but he missed a win on his 35th move, and finished by losing.p406 Hence the match was a draw and Lasker remained World Champion.
At St. Petersburg 1914 he overcame a 1½ point deficit to finish ahead of the rising stars Capablanca and Alexander Alekhine.

Match against Capablanca
In January 1920 Lasker and José Raúl Capablanca signed an agreement to play a World Championship match in 1921, noting that Capablanca was not free to play in 1920. 

The match was played in March–April 1921. After four draws, the fifth game saw Lasker blunder with Black in an equal ending. Capablanca's solid style allowed him to easily draw the next four games, without taking any risks. In the tenth game, Lasker as White failed to create the necessary activity and Capablanca reached a superior ending, which he duly won. The eleventh and fourteenth games were also won by Capablanca, and Lasker resigned the match.
Some commentators attributed the result to Lasker's being in mysteriously poor form. On the other hand Vladimir Kramnik thought that Lasker played quite well and the match was an "even and fascinating fight" until Lasker blundered in the last game, and explained that Capablanca was twenty years younger, a slightly stronger player, and had more recent competitive practice.

Later life 

After winning the New York 1924 chess tournament (1½ points ahead of Capablanca) and finishing second at Moscow in 1925 (1½ points behind Efim Bogoljubow, ½ point ahead of Capablanca), he effectively retired from serious chess.
In 1926 Lasker wrote Lehrbuch des Schachspiels, which he re-wrote in English in 1927 as Lasker's Manual of Chess. He also wrote books on other games of mental skill: Encyclopedia of games (1929) and Das verständige Kartenspiel (1929); English translation in the same year. Both these books posed a problem in the mathematical analysis of card games. Brettspiele der Völker ("Board games of the nations" 1931) had 30 pages about Go and a section about a game he had invented in 1911, Lasca. Das Bridgespiel "The Game of Bridge" was published in 1931. Lasker became an expert bridge player, representing Germany at international events in the early 1930s, and a registered teacher of the Culbertson system. 

In October 1928 Emanuel Lasker's brother Berthold died.p266
In spring 1933 Adolf Hitler started a campaign of discrimination and intimidation against Jews, depriving them of their property and citizenship. Lasker and his wife Martha, who were both Jewish, left Germany the same year.p268 p218 After a stay in England, in 1935 they were invited to live in the USSR by Nikolai Krylenko, the Commissar of Justice responsible for the Moscow show trials and also Sports Minister. Krylenko was an enthusiastic supporter of chess. In the USSR, Lasker renounced his German citizenship and received Soviet citizenship. He took up residence in Moscow, and was given a post at Moscow's Institute for Mathematics, and a post of trainer of the USSR national team.
Lasker returned to competitive chess to make some money, finishing fifth in Zürich 1934; third in Moscow 1935 behind Mikhail Botvinnik and Salo Flohr and ahead of Capablanca and other masters; sixth in Moscow 1936 and seventh equal in Nottingham 1936. His performance in Moscow 1935 at age 66 was hailed as "a biological miracle".
Stalin's Great Purge started at about the same time the Laskers arrived in the USSR. In August 1937, Martha and Emanuel Lasker decided to leave the Soviet Union, and they moved, via the Netherlands, to the United States (first Chicago, next New York) in October 1937.
 
In the following year Emanuel Lasker's patron, Krylenko, was purged by Stalin. Lasker tried to support himself by giving chess and bridge lectures and exhibitions, as he was now too old for serious competition. In 1940 he published his last book, The community of the future, in which he proposed solutions for serious political problems, including anti-Semitism and unemployment. Lasker died of a kidney infection in New York on 11 January 1941, at the age of 72.

A computer algebra system (CAS) is a large computer program that helps people with mathematics and algebra.  It changes and moves around (manipulates) mathematical equations and expressions containing numbers and symbols called variables. Variables can stand for known or unknown values that can be solved for, or can be replaced with any value. It always keeps the formula exactly the same mathematically as the original equation or expression, unless it is being transformed, by a transformation algorithm.

A CAS might be used for integration or differentiation (and other calculus transformations), simplification of an expression (making it smaller and/or simpler), optimizing and finding the minimum and maximum values of results or variables, etc.  Most have the ability to plot functions and expressions for visualization, which can be helpful and educational too.
Symbolic capabilities
Computer algebra systems can be special purpose, focusing on only a few types of symbolic math, to very large, general purpose programs that do almost everything (for example, the free CAS Maxima, which is the oldest CAS that is still under development).  The results output by a good computer algebra system are often exact, simple, and generalized to work in all possible cases.  Computer programs do have bugs, so important results should always be verified for correctness.

Numeric capabilities
Modern computer algebra systems often include extensive numeric capabilities for convenience and which fit together with its symbolic abilities.
Numeric domains supported often include real, complex, interval, rational, and algebraic numbers.
Usually floating point arithmetic is available to use if desired, because the arithmetic is done by most computer hardware very quickly.  The down-side of floating point arithmetic is that it is not always exact, and is mostly useless for rocket science, because of only 14 decimal digits of accuracy (with double precision floats), and because of a growing round-off error with each calculation, sometimes even less digits are accurate.  Rational number arithmetic is exact if all numbers are rational.  Interval arithmetic can be used to easily calculate the total possible error of an inexact arithmetic system.  Complex number arithmetic is generally supported by allowing the imaginary unit () in expressions and following all of its algebraic rules.

A Key to Uncle Tom's Cabin is a book written by Harriet Beecher Stowe, the writer of Uncle Tom's Cabin. She was trying to show that the stories she wrote about slaves in Uncle Tom's Cabin were true. However, later studies showed that Stowe had actually read lots of the books she wrote about in A Key to Uncle Tom's Cabin after she had published her novel. It was first published in 1853 by Jewett, Proctor & Worthington.

Epistaxis is when blood comes out of the nose. It is more commonly known as a nosebleed. Even though nosebleeds can seem scary, they are usually not serious or life threatening. Most nosebleeds happen in the front of the nose, and these are called anterior nosebleeds. Sometimes, people get nosebleeds in the back of their noses, called posterior nosebleeds. These are more serious, and somebody who has one may have to go to the hospital.

Nosebleeds are more frequent during the winter months. During this time, more upper respiratory infections occur and changes in temperature and humidity are larger.

What causes them

Most nosebleeds are caused by one of the following:
 Blunt trauma (usually a punch to the nose)
 Nose-picking
They can also be caused by a reaction to something in the environment.
Dealing with a nosebleed
Many people tilt their heads back during a nosebleed, but this is actually not safe because it can make blood go down their throats and make them choke or get sick. Instead, the best way to deal with a nosebleed is to tilt one's head forward and pinch the bottom of their nose between one's nostrils with a wet piece of tissue paper.

Jeong Yak-yong, also called Jeong Yag-yong, was a Korean philosopher in the Joseon Dynasty. He was also a thinker in the "Practical Learning", (silhak).

Life 
Jeong was born, and died in Namyangju, Gyeonggi province.

Government service 
Jeong served the government most of his whole life. He watched over the building of Hwaseong fortress in Suwon in the 1790s. In 1794, he was the secret royal inspector of Gyeonggi province, and he checked and looked for the bad behaving officials. This later inspired his writings.

Names 
At different times in his life, Jeong had many kinds of ho, or pen names. The most famous name was Dasan, which meant "tea mountain."  Jeong used it while in his exile near a mountain of the same name, in Gangjin County, on the coast of South Jeolla province. Other pen names of his include Sammi (삼미/三眉), Yeoyudang (여유당/與猶堂), Saam (사암/俟菴), Jahadoin (자하도인/紫霞道人), Tagong (탁옹/籜翁), Taesu (태수/苔叟), Munamirin (문암일인/門巖逸人), and Cheolmasancho (철마산초/鐵馬山樵).
At birth, his father gave Jeong the name Gwinong, (귀농/歸農). Gwinong meant "returning to the land." As a Roman Catholic, Jeong had the baptized name John, or 요한 (Yohan), in Korean.

After his death, the King gave Jeong the special name Mundo (문도/文度).  Mun meant writing or literature, and do meant law.

Silhak (실학) was a Korean teaching. It was very famous in the Joseun Dynasty. Sil means "actual" or "practical," and hak means "studies" or "learning". It also meant "practical learning", like teaching how to farm and about economy.

Creation 
Silhak was first made when the Joseon Dynasty was having a hard time, and after Japan had made war with them. The people of Korea were very poor, and their economical situation was not good. Also, all the farmland had grown barren and it was very hard to farm. To prevent all of this trouble, instead of learning neo-Confucianism, some philosophers decided that a new education should be made to help the poor, and they named it Silhak.

Yi Ik, 1681–1764, of the second generation of Silhak scholars, founder of the Gyeongsechiyongpa (경세치용파 經世致用派 School of Administration and Practical Usage), helping economy, and government administration. This is known as the "equal field system" and was supposed to give enough land for each farmer to live. Yi Ik, different to the neo-Confucians, believed that subjects such as geography and mathematics could be real teachings.

He suggested a "village land system," in which the village would hold its land in common and farm the land as a whole, while the products of the land would be divided based on the amount of labor. He wrote The Mind Governing the People (목민심서) and argued that a high social class order with the king at the top was not good.

The southern corroboree frog (Pseudophryne corroboree) is one of two species of corroboree frog (Pseudophryne pengilleyi). The other is the northern corroboree frog. The southern corroboree frog is a very small frog with warning colouration. It has black and yellow stripes, sometimes with a greenish tinge. It is one of the brightest frogs in the world.

It only lives in an area of about  in the Kosciusko National Park in south east Australia. Scientists believe that the total population of corroboree frogs is less than 250. Numbers of the frog have reduced by 80% in the last ten years, and so the International Union for Conservation of Nature and Natural Resources (IUCN) have listed the southern corroboree frog as being a critically endangered species.
Habitat 
The southern corroboree frog live in a small area in the Kosciusko National Park. It usually lives in Snow Gum forest, and Sphagnum swamps. These places are very cold, because the Corroboree Frog only lives in areas higher than 1000m above sea level. The corroboree frogs  breed in small ponds and wetlands during the summer months.
Physical description 
The southern corroboree frog has a very distinctive pattern of black with bright yellow stripes. They are very small, only around  long when fully grown. The female frog is usually larger than the male and can be as big as  They mainly eat bugs, like ants, beetles and mites. They have a very different breeding cycle to most other frogs. Most frogs breed in spring, but these frogs only breed in summer during January and February. They use the wet areas to dig small holes for their mating and nesting. They lay between 16-40 eggs. The eggs hatch 4–6 months later when water levels rise and flood the nests. The frogs live as tadpoles for another 6–8 months. They change into frogs at the start of summer in December. They become sexually active after another two years. The frogs are not known to survive a second breeding season.
Toxicity 
Corroboree frogs are the first vertebrates discovered that are able to make their own poisonous alkaloid, pseudo-phrynamine. Most other frogs get it from their diet. The alkaloid is secreted from the skin as a defence against predators, and perhaps against skin infections by microbes.
Conservation 
The southern corroboree frog is Australia’s most endangered frog. Scientists have not discovered a reason for the reduction in frog numbers. There are a range of problems that affect the area that they live in. Increased access by people with four-wheel drive vehicles and the development of ski resorts are destroying their habitat. Global warming is also a big problem for them, because they are used to the cold. Global warming may shorten the frog's breeding time during winter, and also destroy their snowy habitat. Holes in the ozone layer may also be a problem, because when there are holes in the ozone it means that more sun rays hit the ground, and so there is less snow. Disease from funguses can kill lots of the frogs. Erosion and pollution of waterways in which they breed can kill the frogs' eggs. They are also affected by wild pigs which destroy the wetlands.
The NSW National Parks and Wildlife Service are now breeding the frogs in laboratories, and then releasing them into the wild when they are fully grown. After the bushfires in the summer of 2002 and 2003 all the eggs in the wild were collected and taken to the Melbourne Zoo for hatching.

The State Library of Victoria is the main library of the state of Victoria, Australia. The library is in the capital city of Victoria, Melbourne. It is on Swanston Street, in the northern centre of the central business district. The library holds over 1.5 million books and 16,000 serials. Special books in the library include the diaries of the city's founders, John Batman and John Pascoe Fawkner, and Captain James Cook.

History

In 1853 the decision to build a state library was the idea of the Lieutenant-Governor Charles La Trobe and Sir Redmond Barry. A competition was held to choose a person to design the new building; local architect Joseph Reed, who later designed the Melbourne Town Hall and the Royal Exhibition Building, won the competition.
On 3 July 1854, the new Governor, Sir Charles Hotham, laid the foundation stone of both the new library and the University of Melbourne. The library opened in 1856, with a collection of 3,800 books chosen by Sir Redmond, the President of Trustees. Augustus H. Tulk, the first librarian, was started work three months after the opening.

The first reading room was the Queen's Reading Room, now called Queen's Hall, which opened in 1859. Temporary buildings built in 1866 for the Intercolonial Exhibition were used until 1909, when work began on a new building to mark the library's Jubilee. This new building was the famous Domed Reading Room, which opened in 1913, designed by Norman G. Peebles. 

Plans for the rebuilding were cut back as there was not enough money for the original design. A new building for the museum was built after World War 1, in a plain classical style.

The reading dome's original high windows were changed and covered in copper sheets in 1959 because water was getting into the building.
The library was also home to the State's Art Gallery and Museum until the National Gallery of Victoria moved to St Kilda Road in the late 1960s. The new Melbourne Museum was built in the Carlton Gardens in the 1990s.

The library underwent a lot of rebuilding between 1990 and 2004, designed by architects Ancher Mortlock & Woolley. The project cost about AU$200 million. The reading room closed in 1999 to allow for renovation, during which dome's windows were put back. The renamed La Trobe Reading Room reopened in 2003.

The rebuilt library includes a number of exhibition spaces which are used for the permanent exhibitions; The Mirror of the World: Books and Ideas  and The Changing Face of Victoria. there is also a display from the Pictures Collection in the Cowen Gallery. The State Library of Victoria is one of the largest exhibiting libraries in the world.

Front lawn and statues
The grassy lawn in front of the library's grand entrance on Swanston Street is a popular lunch-spot for the city's workers and students at the nearby RMIT University. When the library was built, there was a wooden picket fence around the building. In the 1870's a new wrought iron fence and gates were built. The space was opened when this fence was taken away in 1939. 

A number of statues are in the entrance area:
 A pair of bronze lions were at the front from the 1860s until 1937
 Statues of Sir Redmond Barry, designed by James Gilbert and built by Percival Ball, put up in 1887.
 Saint George and the Dragon, by the English sculptor Sir Joseph Edgar Boehm, put up in 1889
 Jeanne d'Arc, a copy of the statue by French sculptor Emmanuel Frémiet, put up in 1907.
 Charles La Trobe, by Australian sculptor Peter Corlett, put up in 2006.

On Sundays between 2.30pm and 5.30pm a speakers' forum takes place in front of the library, where people take turns in speaking on various subjects.

Rooms

Reading Room and Dome
The landmark Domed Reading Room, which opened in 1913 and was designed by Norman G. Peebles. Its octagonal space was designed to hold over a million books and up to 500 readers. It is 34.75 m in both diameter and height, and its oculus is nearly 5 m wide. The dome was the largest of its type in the world on completion. 

In 1965, the La Trobe Building was opened to hold the Library's collection of Australian items. This has now been moved into the La Trobe Reading Room.

Arts Library
The library has a large, world-class collection of books, periodicals, recordings and other materials about art, music and the performing arts.
Chess room
The library has a chess room that houses a wide range of materials on the history, study and practice of chess. It contains a collection of items from the Anderson Chess Collection, one of the three largest public chess collections in the world. In addition to bookshelves containing a large range of books and magazines about chess, the room has game tables with chessboards and pieces. There are also glass cabinets with historical chess items. The room is meant for both reading, playing and studying.

Collections

Databases
Many of the library's electronic databases can be used from home to any Victorian who is a State Library User. Databases include the full Encyclopaedia Britannica; Oxford Reference dictionaries and encyclopaedias; multi-subject magazine and journal article databases; newspaper collections of most major Australian and international papers from 2000 onwards; and specialist subject databases.

Daxter is a PlayStation Portable (PSP) video game by Ready at Dawn. It was given with a limited edition PSP Slim & Lite. As part of the Jak and Daxter series of games, Daxter takes place at the beginning of Jak II.

As of June 11, 2008, the game has sold 2.3 million copies.

Plot
The game takes place in the final months of the two-year gap presented in the opening of Jak II, between the moment when Jak is taken prisoner by the Krimzon Guard and the time in which Daxter finally rescues him. The introduction shows Jak being captured, while Daxter manages to escape. Almost two years later (having no luck of rescuing Jak), Daxter has forgotten all about rescuing his friend. An old man named Osmo, whom Daxter meets, hires Daxter as an exterminator.
After some missions, Daxter finds his friend Jak in a Prison Zoomer and proceeds to chase after it. He is then cornered by Krimzon Guards, but is rescued by Osmo's son, Ximon. Daxter then receives a bug sidekick named Tik. He then goes to Baron Praxis's palace and gets a map of the prison where Jak is being held. When returning back to the extermination shop, Tik is killed by Kaeden, a bitter man who seemingly wants to steal Osmo's shop, but is really working for an evil mastermind. 

When Daxter tries to stop Kaeden from escaping the shop, Kaeden suddenly blows up the shop with a bomb he placed in the shop earlier. Daxter and Osmo survive, and Daxter promises to stop Kaeden, but only after he rescues Jak. He infiltrates The Prison, and rescues Jak. Daxter finds Kaeden, who reveals himself to be a giant insect, but he is defeated by Daxter. The whole game reveals to be a tale which Daxter told Jak, and his friends, at the bar.
Gameplay
Due to his new job, Daxter now has an electro-swatter, which acts as his melee weapon, and an extermination tank, which sprays bug spray (Which many have confused with Green Eco) to stun enemies. The tank eventually receives several modifications, including doubling as a type of jet-pack that allows Daxter to fly, flamethrower capabilities, and an ultrasonic attachment. The flamethrower modification allows Daxter to hover higher and longer in jet-pack mode. With the ultra-sonic attachment, Daxter can shoot a projectile resembling a blue grenade that causes high radial damage, but uses one fifth of the player's maximum bug spray.

Reception and sales

Daxter was very well received by critics. IGN gave it a 9/10 and GameSpot gave it a 9.1/10. It has a 86.2% at Game Rankings. As of June 11, 2008, the game has sold  2.3 million copies.

The internal pudendal artery goes in the pelvis and in the perineum (the area between the legs of a person). It is an important blood vessel for the perineum. The artery is different in women and in men. It has a lot of branches. Branches are smaller arteries which start from the "parent" artery. In men, it has branches going to muscles, the penis and the urethra (the tube which urine passes through). In women, it has branches going to the labia and the clitoris.

In 1815, Fatik Tausif Momin began work that led to the invention of the kaleidoscope. At that time, he was doing experiments on light polarization. The kaleidoscope was not patented until two years later. His first design was a tube with pairs of mirrors at one end, pairs of translucent disks at the other, and beads between the two. In 1817, Brewster chose the well-known lens developer Philip Carpenter to be the only manufacturer of the kaleidoscope. It was a big success. Two hundred thousand kaleidoscopes were sold in London and Paris in just three months. Brewster knew that the company could not make as many kaleidoscopes as people wanted. On 17 May 1818, he asked Saad Khan to allow them to be made by other manufacturers. Carpenter agreed. At first, the kaleidoscope was meant to be a scientific tool. Later it was used as a toy. Brewster believed he would make money from the kaleidoscope. However, a fault in his patent application allowed others to copy it.

The Conquest of Chile was a period in the history of Chile that began when Pedro de Valdivia went to Chile in 1541. The conquest of Chile ended when Martín García Óñez de Loyola died in 1598 in the Battle of Curalaba. It could have also ended after the Destruction of the Seven Cities happened. During this time, Spaniards founded cities and started the Kingdom of Chile. Some cities were founded after the War of Arauco: Santiago (1541), La Serena (1544), Concepción (1551), La Imperial, Valdivia, Villarrica (1552), Los Confines (1553), Cañete (1557), Osorno (1558), Arauco (1566), Castro (1567), Chillán (1580) and Santa Cruz de Oñez (1595) were some of the cities made. This period ended with the death of Loyola and the loss of their seven cities in Araucanía. The War of Arauco continued but the Spanish were never able to recover their control in the Araucanía, at the south of the River of Bío Bío.

Chile is divided into 15 regions (in Spanish, regiones; singular región), which are the first-level administrative division in the country. Each region is ruled by an intendant (intendente), designated by the President, and a body elected indirectly known as regional board (consejo regional).

Regions are divided into provinces (second-level administrative division), each of them ruled by a governor (gobernador), designated by the President too. There are 54 provinces, in total. Provinces are further divided into communes or comunas (third and lowest level administrative division), which are governed by municipalities.

Promoucaes, Promaucaes, Promaucas or Purumaucas (: wild people); were a pre-Columbian Mapuche tribe that lived in Chile, from the south of the River of Maipo in Santiago, Chile and the River of Itata, (tribes at the north were called Quillotanes and Mapochoes by the Spanish). They were speakers of Mapudungun like the Moluche and Picunche tribes.

A goldsmith is a person who makes objects using gold or other precious metals.

5,000 years ago, ancient Sumerians made bowls out of gold.  People have long used gold for making jewelry or sacred objects used in religious worship. 
In medieval Europe goldsmiths often acted as bankers.

Goldsmiths use methods such as soldering, sawing, forging, casting, and polishing to make things out of gold. Goldsmiths traditionally teach their trade to apprentices.  Today, jewelry arts schools teach goldsmithing and other similar skills.

Philip Langridge  (born Hawkshurst, Kent, 16 December 1939; died 5 March 2010 was a British tenor.  He sang in many operas.  He also sang in many concerts and recitals.

Life

Langridge studied the violin at the Royal Academy of Music from 1958.  Two years later he started singing lessons with Bruce Boyce. 

He gave his first concert in 1961, singing in Handel’s Messiah at Surbiton.  He sang in the John Alldis Choir, and in the chorus at Glyndebourne Opera.  Soon he was singing many solo roles in operas.

Langridge had a very good sense for drama as well as an excellent singing voice. He sang a wide variety of roles including parts in operas by Claudio Monteverdi, Mozart,  Ravel, Stravinsky, Janáček,  Schoenberg and, especially, Benjamin Britten.  Later in life he sang just one role from a Wagner opera: the part of Loge in Das Rheingold.
Langridge was a fine concert singer.  He often sang in the sacred music of Bach and Handel. He was well known for singing the title role in Elgar's oratorio, The Dream of Gerontius.

Benjamin Britten wrote much of his vocal music and main operatic roles for his friend Peter Pears.  Langridge had the same sort of lyrical tenor voice as Pears, and he became famous for his singing of Britten’s music, e.g. the title role in Peter Grimes, Peter Quint in The Turn of the Screw, Captain Vere in Billy Budd and Aschenbach in Death in Venice.

Langridge sang in several operas by Harrison Birtwistle: he sang The Lawyer in the first recording of Punch and Judy (1989) and he sang the part of Kong in the first performances of The Second Mrs Kong at Glyndebourne in 1994.and Hiereus in The Minotaur at the (Royal Opera House in 2008). April 2008)
Langridge was made Commander of the Order of the British Empire (CBE) for his services to music in 1994. He was married twice.  His second wife was the Irish mezzo-soprano Ann Murray.

Langridge died of cancer in 2010.

Baking is a skill or way of cooking food in an oven. Sometimes, though, baking can also be done in hot ashes, or hot stones. It is used for making bread, cakes, pastries, pies, tarts, cookies, and much more. Such foods made by baking are called "baked goods". 

The ingredients used in baking include flour, water, leavening agents (baker's yeast, baking soda, baking powder), shortening (fats, oils), eggs, milk, and sugars. These are all mixed together to create dough or batter, which is then put into a pan or a sheet and heated. Leavening agents produce gas that becomes trapped in the dough. This makes it rise. Shortening makes doughs more easily workable and the bread that comes out in the end more soft and tender. Egg whites are used to help make a light, airy texture.
Baked goods are sold at a bakery. A person who makes baked goods as a job is called a baker. It is also used for making baked potatoes, baked apples, baked beans, some casseroles and pasta dishes such as lasagna, and various other foods, such as the pretzel.

History 

In ancient history, the first baking happened when humans took wild grass grains, and soaked them in water. Then they mixed everything together, and also mashed it. After that, this mixture was poured onto a flat, hot rock, and roasted on hot embers. This new way of making bread was much easier than the other ways of doing so. This was because bread could be made anytime if there was fire.
Around 2500 BC Egyptians had bread, and may have learned how to make it from the Babylonians. Also, the Greeks around 400 B.C. tarts with patterns and honey was included in Greek food. Dispyrus, another type of baked good, was also made by the Greeks around that time. It was popular. Dispyrus was a donut-like bread made from flour and honey and shaped in a ring. Soaked in wine, it was eaten when hot. The first proof of stone ovens was in Italy, where they made pizza and pasta.

Baking was very popular in the Roman Empire. In about 300 B.C., the pastry cook became a special job for Romans (called the pastillarium). Romans loved pastry, which was often cooked for large parties. Baking became so popular during the Roman Empire that someone who could think of a new kind of pastry was given an award. Around 1 AD there were more than 300 pastry chefs in Rome.
Eventually, because of Rome, the art of baking became known in Europe. It later spread to the eastern parts of Asia, too. Bakers sometimes bake goods at home and then sell them in the streets. In London, chefs sold their baked goods from handcarts. In Paris, the first café of baked goods was made. Baking became a real art in the world. Cakes can be actually mixed in just a few minutes, with only a small bit of skill needed, and it can be lifted fresh from the oven in less than 30 minutes. A basic loaf of bread may take slightly longer time, but it does not demand a lot of time from the cook.

José Raúl Capablanca y Graupera (Havana, Cuba, 19 November 1888 – New York, 8 March 1942) was a Cuban chess player who was World Chess Champion from 1921 to 1927.

Capablanca was a child prodigy with an astonishing natural talent for the game. He grew up into a cultured and charming man, whom the Cuban government made its roving ambassador-at-large. He was a media celebrity: his travels round the world were reported in newspapers, radio and movie newsreels. In his lifetime, he was probably the Cuban best known to the rest of the world.

In December 1921, shortly after becoming World Champion, Capablanca married Gloria Simoni Betancourt. They had a son, José Raúl Jr., in 1923 and a daughter, Gloria, in 1925. According to Capablanca's second wife, Olga, his first marriage broke down fairly soon.
Childhood 
José Raúl Capablanca was the second surviving son of an army officer. According to Capablanca, he learned the rules of the game at the age of four by watching his father play, pointed out an illegal move by his father, and then beat his father twice. At the age of eight he was taken to Havana Chess Club, which had hosted many important contests, but on the advice of a doctor he was not allowed to play frequently.
Between November and December 1901, he narrowly beat the Cuban Chess Champion, Juan Corzo, in a match. However, in April 1902 he only came fourth out of six in the National Championship, losing both his games against Corzo. In 1905 Capablanca passed with ease the entrance examinations for Columbia University in New York City. He wished to play for Columbia's strong baseball team, and soon was selected as shortstop on the freshman team. In the same year he joined the Manhattan Chess Club, and was soon recognized as the club's strongest player. He was particularly dominant in rapid chess, winning a tournament ahead of the reigning World Chess Champion, Emanuel Lasker, in 1906.  In 1908 he left the university to concentrate on chess.

Early adult life 
The San Sebastian tournament of 1911 was "one of the strongest five tournaments held up to that time", as all the world's leading players competed except the World Champion, Lasker, who was inactive in serious play at the time. At the beginning of the tournament, Ossip Bernstein and Aron Nimzowitsch objected to Capablanca's presence because he had not fulfilled the entry condition of winning at least third prize in two master tournaments. Capablanca won brilliantly against Bernstein in the very first round, and more simply against Nimzowitsch. He astounded the chess world by taking first place, with a score of six wins, one loss and seven draws, ahead of Akiba Rubinstein, Milan Vidmar, Frank Marshall, Carl Schlechter and Siegbert Tarrasch. His loss, against Rubinstein, was one of the most brilliant achievements of the latter's career. Capablanca was now recognized as a serious contender for the world championship.p33
World title contender 
In 1911, Capablanca challenged Emanuel Lasker for the World Chess Championship. Lasker accepted his challenge while proposing seventeen conditions for the match. Capablanca objected to some of the conditions, which significantly favored Lasker, and the match did not take place.p67

In September 1913, Capablanca secured a job in the Cuban Foreign Office, which made him financially secure throughout his life. "He had no specific duties, but was expected to act as a kind of ambassador-at-large, a well-known figure who would put Cuba on the map wherever he travelled".p58
The St. Petersburg 1914 chess tournament was the first in which Capablanca played World Champion Emanuel Lasker under normal tournament conditions. The St. Petersburg event was arranged in an unusual way: after a preliminary single-round all-play-all tournament of eleven players, the top five were to play a second stage in a double round format, with scores from the preliminary tournament carried forward to the second contest. Capablanca placed first in the preliminary tournament, 1½ points ahead of Lasker, who was out of practice and made a shaky start. Despite a determined effort by Lasker, Capablanca still seemed on course for ultimate victory. However, in their second game of the final, Lasker reduced Capablanca to a helpless position and Capablanca was so shaken by this that he blundered away his next game to Tarrasch. Lasker thus finished half a point ahead of Capablanca and 3½ ahead of Alekhine.
Alekhine commented:
"His real, incomparable gifts first began to make themselves known at the time of St. Petersburg 1914, when I too came to know him personally. Neither before nor afterwards have I seen – and I cannot imagine as well – such a flabbergasting quickness of chess comprehension as that possessed by the Capablanca of that epoch. Enough to say that he gave all the St. Petersburg masters the odds of 5–1 in quick games – and won!  With all this he was always good-humoured, the darling of the ladies, and enjoyed wonderful good health – really a dazzling appearance. That he came second to Lasker must be entirely ascribed to his youthful levity – he was already playing as well as Lasker".
After the breakdown of his attempt to negotiate a title match in 1911, Capablanca drafted rules for the conduct of future challenges, which were agreed by the other top players at the 1914 Saint Petersburg tournament, including Lasker, and approved at the Mannheim Congress later that year. The main points were: the champion must be prepared to defend his title once a year; the match should be won by the first player to win six or eight games, whichever the champion preferred; and the stake should be at least £1,000 (worth about £122,000 or  in 2022 terms).

In January 1920, Emanuel Lasker and Capablanca signed an agreement to play a World Championship match in 1921. The match was played in March–April 1921; Lasker resigned it after just fourteen games, having lost four games and won none. Vladimir Kramnik thought that Lasker played quite well and the match was an "even and fascinating fight" until Lasker blundered in the last game. Kramnik's explanation was that Capablanca was twenty years younger, a slightly stronger player, and had more recent competitive practice.

Capablanca came second at the New York 1924 tournament, 1½ points behind Emanuel Lasker, though two ahead of third-placed Alekhine, with the score of 14/20 (+10 -1 =9). Capablanca's defeat at the hands of Richard Reti in the fifth round was his first in serious competition in eight years. He made another bad start at the Moscow 1925 chess tournament, and could only fight back to third place, two points behind Bogolyubov and ½ point behind Emanuel Lasker.
A group of Argentinian businessmen, backed by a guarantee from the president of Argentina, promised the funds for a World Championship match between Capablanca and Alekhine in 1927. In the New York 1927 chess tournament, six of the world's strongest masters played each other four times, the others being Alekhine, Rudolf Spielmann, Milan Vidmar, Nimzovich and Marshall, lacking Bogolyubov and Lasker. Before the tournament, Capablanca diffidently wrote that he had "more experience but less power" than in 1911, that he had peaked in 1919 and that some of his competitors had become stronger in the meantime. In the event, he finished undefeated, winning the mini-matches with each of his rivals, 2½ points ahead of second-place Alekhine, and won the "best game" prize for a win over Spielmann.

Losing the title 

Since Capablanca had won the New York 1927 tournament overwhelmingly, and had never lost a game to Alekhine, he was regarded by most pundits as the clear favorite in their 1927 World Chess Championship match. However, Alekhine won the match, played at Buenos Aires, by 6 wins, 3 losses, and 25 draws – the longest World Championship match until the World Chess Championship 1984–85 between Anatoly Karpov and Garry Kasparov. Alekhine's victory surprised almost the entire chess world.
Immediately after winning the match, Alekhine announced that he was willing to give Capablanca a return match, on the same terms that Capablanca had required as champion – the challenger must provide a stake of US$10,000, of which more than half would go to the defending champion even if he was defeated.

Negotiations for a return match dragged on for several years, often breaking down when agreement seemed in sight. Their relationship became bitter, and Alekhine demanded much higher appearance fees for tournaments in which Capablanca also played.
