Cloud Gate is a public sculpture by Indian-born British artist Anish Kapoor, that is the centerpiece of AT&T Plaza at Millennium Park in the Loop community area of Chicago, Illinois. The sculpture and AT&T Plaza are located on top of Park Grill, between the Chase Promenade and McCormick Tribune Plaza & Ice Rink. Constructed between 2004 and 2006, the sculpture is nicknamed "The Bean" because of its shape, a name Kapoor initially disliked, but later grew fond of. Kapoor himself even uses this title when referring to his work. Made up of 168 stainless steel plates welded together, its highly polished exterior has no visible seams. It measures 33 by 66 by 42 feet (10 by 20 by 13 m), and weighs 110 short tons (100 t; 98 long tons).
Kapoor's design was inspired by liquid mercury and the sculpture's surface reflects and distorts the city's skyline. Visitors are able to walk around and under Cloud Gate's 12-foot (3.7 m) high arch. On the underside is the "omphalos" (Greek for "navel"), a concave chamber that warps and multiplies reflections. The sculpture builds upon many of Kapoor's artistic themes, and it is popular with tourists as a photo-taking opportunity for its unique reflective properties.
The sculpture was the result of a design competition. After Kapoor's design was chosen, numerous technological concerns regarding the design's construction and assembly arose, in addition to concerns regarding the sculpture's upkeep and maintenance. Various experts were consulted, some of whom believed the design could not be implemented. Eventually, a feasible method was found, but the sculpture's construction fell behind schedule. It was unveiled in an incomplete form during the Millennium Park grand opening celebration in 2004, before being concealed again while it was completed. Cloud Gate was formally dedicated on May 15, 2006, and has since gained considerable popularity, both domestically and internationally.
Sir Anish Mikhail Kapoor, CBE, RA (born 12 March 1954) is a British-Indian sculptor specializing in installation art and conceptual art. Born in Mumbai, Kapoor attended the elite all-boys Indian boarding school The Doon School, before moving to the UK to begin his art training at Hornsey College of Art and, later, Chelsea School of Art and Design.
His notable public sculptures include Cloud Gate (2006, also known as "The Bean") in Chicago's Millennium Park; Sky Mirror, exhibited at the Rockefeller Center in New York City in 2006 and Kensington Gardens in London in 2010; Temenos, at Middlehaven, Middlesbrough; Leviathan, at the Grand Palais in Paris in 2011; and ArcelorMittal Orbit, commissioned as a permanent artwork for London's Olympic Park and completed in 2012. In 2017, Kapoor designed the statuette for the 2018 Brit Awards.
An image of Kapoor features in the British cultural icons section of the newly designed British passport in 2015. In 2016, he was announced as a recipient of the LennonOno Grant for Peace.
Kapoor has received several distinctions and prizes, such as the Premio Duemila Prize at the XLIV Venice Biennale in 1990, the Turner Prize in 1991, the Unilever Commission for the Turbine Hall at Tate Modern, the Padma Bhushan by the Indian government in 2012, a knighthood in the 2013 Birthday Honours for services to visual arts, an honorary doctorate degree from the University of Oxford in 2014. and the 2017 Genesis Prize for "being one of the most influential and innovative artists of his generation and for his many years of advocacy for refugees and displaced people".
Millennium Park is a public park located in the Loop community area of Chicago, operated by the Chicago Department of Cultural Affairs. The park, opened in 2004 and intended to celebrate the third millennium, is a prominent civic center near the city's Lake Michigan shoreline that covers a 24.5-acre (9.9 ha) section of northwestern Grant Park. Featuring a variety of public art, outdoor spaces and venues, the park is bounded by Michigan Avenue, Randolph Street, Columbus Drive and East Monroe Drive. In 2017, Millennium Park was the top tourist destination in Chicago and in the Midwest, and placed among the top ten in the United States with 25 million annual visitors.
Planning of the park, situated in an area occupied by parkland, the Illinois Central rail yards, and parking lots, began in October 1997. Construction began in October 1998, and Millennium Park was opened in a ceremony on July 16, 2004, four years behind schedule. The three-day opening celebrations were attended by some 300,000 people and included an inaugural concert by the Grant Park Orchestra and Chorus. The park has received awards for its accessibility and green design. Millennium Park has free admission, and features the Jay Pritzker Pavilion, Cloud Gate, the Crown Fountain, the Lurie Garden, and various other attractions. The park is connected by the BP Pedestrian Bridge and the Nichols Bridgeway to other parts of Grant Park. Because the park sits atop parking garages, the commuter rail Millennium Station and rail lines, it is considered the world's largest rooftop garden. In 2015, the park became the location of the city's annual Christmas tree lighting.
Some observers consider Millennium Park the city's most important project since the World's Columbian Exposition of 1893. It far exceeded its originally proposed budget of $150 million. The final cost of $475 million was borne by Chicago taxpayers and private donors. The city paid $270 million; private donors paid the rest, and assumed roughly half of the financial responsibility for the cost overruns. The construction delays and cost overruns were attributed to poor planning, many design changes, and cronyism. Many critics have praised the completed park.
From 1852 until 1997, the Illinois Central Railroad owned a right of way between downtown Chicago and Lake Michigan, in the area that became Grant Park and used it for railroad tracks. In 1871, Union Base-Ball Grounds was built on part of the site that became Millennium Park; the Chicago White Stockings played home games there until the grounds were destroyed in the Great Chicago Fire. Lake Front Park, the White Stockings' new ball grounds, was built in 1878 with a short right field due to the railroad tracks. The grounds were improved and the seating capacity was doubled in 1883, but the team had to move after the season ended the next year, as the federal government had given the city the land "with the stipulation that no commercial venture could use it". Daniel Burnham planned Grant Park around the Illinois Central Railroad property in his 1909 Plan of Chicago. Between 1917 and 1953, a prominent semicircle of paired Greek Doric-style columns (called a peristyle) was placed in this area of Grant Park (partially recreated in the new Millennium Park). In 1997, when the city gained airspace rights over the tracks, it decided to build a parking facility over them in the northwestern corner of Grant Park. Eventually, the city realized that a grand civic amenity might lure private dollars in a way that a municipal improvement such as ordinary parking structure would not, and thus began the effort to create Millennium Park. The park was originally planned under the name Lakefront Millennium Park.
The park was conceived as a 16-acre (6.5 ha) landscape-covered bridge over an underground parking structure to be built on top of the Metra/Illinois Central Railroad tracks in Grant Park. The parks overall design was by Skidmore, Owings & Merrill, and gradually additional architects and artists such as Frank Gehry and Thomas Beeby were incorporated into the plan. Sponsors were sought by invitation only.
In February 1999, the city announced it was negotiating with Frank Gehry to design a proscenium arch and orchestra enclosure for a bandshell, as well as a pedestrian bridge crossing Columbus Drive, and that it was seeking donors to cover his work. At the time, the Chicago Tribune dubbed Gehry "the hottest architect in the universe"[19] in reference to the acclaim for his Guggenheim Museum Bilbao, and they noted the designs would not include Mayor Richard M. Daley's trademarks, such as wrought iron and seasonal flower boxes. Millennium Park project manager Edward Uhlir said "Frank is just the cutting edge of the next century of architecture," and noted that no other architect was being sought. Gehry was approached several times by Skidmore architect Adrian Smith on behalf of the city. His hesitance and refusal to accept the commission was overcome by Cindy Pritzker, the philanthropist, who had developed a relationship with the architect when he won the Pritzker Prize in 1989. According to John H. Bryan, who led fund-raising for the park, Pritzker enticed Gehry in face-to-face discussions, using a $15 million funding commitment toward the bandshell's creation. Having Gehry get involved helped the city realize its vision of having modern themes in the park; upon rumors of his involvement the Chicago Sun-Times proclaimed "Perhaps the future has arrived", while the Chicago Tribune noted that "The most celebrated architect in the world may soon have a chance to bring Chicago into the 21st Century".
Plans for the park were officially announced in March 1998 and construction began in September of that year. Initial construction was under the auspices of the Chicago Department of Transportation, because the project bridges the railroad tracks. However, as the project grew and expanded, its broad variety of features and amenities outside the scope of the field of transportation placed it under the jurisdiction of the city's Public Buildings Commission.
In April 1999, the city announced that the Pritzker family had donated $15 million to fund Gehry's bandshell and an additional nine donors committed $10 million. The day of this announcement, Gehry agreed to the design request. In November, when his design was unveiled, Gehry said the bridge design was preliminary and not well-conceived because funding for it was not committed. The need to fund a bridge to span the eight-lane Columbus Drive was evident, but some planning for the park was delayed in anticipation of details on the redesign of Soldier Field. In January 2000, the city announced plans to expand the park to include features that became Cloud Gate, the Crown Fountain, the McDonald's Cycle Center, and the BP Pedestrian Bridge. Later that month, Gehry unveiled his new winding design for the bridge.
Mayor Daley's influence was key in getting corporate and individual sponsors to pay for much of the park. Bryan, the former chief executive officer (CEO) of Sara Lee Corporation who spearheaded the fundraising, says that sponsorship was by invitation and no one refused the opportunity to be a sponsor. One Time magazine writer describes the park as the crowning achievement for Mayor Daley, while another suggests the park's cost and time overages were examples of the city's mismanagement. The July 16–18, 2004, opening ceremony was sponsored by J.P. Morgan Chase & Co.
The community around Millennium Park has become one of the most fashionable and desired residential addresses in Chicago. In 2006, Forbes named the park's 60602 zip code as the hottest in terms of price appreciation in the country, with upscale buildings such as The Heritage at Millennium Park (130 N. Garland) leading the way for other buildings, such as Waterview Tower, The Legacy and Joffrey Tower. The median sale price for residential real estate was $710,000 in 2005 according to Forbes, also ranking it on the list of most expensive zip codes. The park has been credited with increasing residential real estate values by $100 per square foot ($1,076 per m2).
Millennium Park is a portion of the 319-acre (129.1 ha) Grant Park, known as the "front lawn" of downtown Chicago, and has four major artistic highlights: the Jay Pritzker Pavilion, Cloud Gate, the Crown Fountain, and the Lurie Garden. Millennium Park is successful as a public art venue in part due to the grand scale of each piece and the open spaces for display. A showcase for postmodern architecture, it also features the McCormick Tribune Ice Skating Rink, the BP Pedestrian Bridge, the Joan W. and Irving B. Harris Theater for Music and Dance, Wrigley Square, the McDonald's Cycle Center, the Exelon Pavilions, the AT&T Plaza, the Boeing Galleries, the Chase Promenade, and the Nichols Bridgeway.
Millennium Park is considered one of the largest green roofs in the world, having been constructed on top of a railroad yard and large parking garages. The park, which is known for being user friendly, has a very rigorous cleaning schedule with many areas being swept, wiped down or cleaned multiple times a day. Although the park was unveiled in July 2004, some features opened earlier, and upgrades continued for some time afterwards. Along with the cultural features above ground (described below) the park has its own 2218-space parking garage
Chicago is the most populous city in the U.S. state of Illinois and in the Midwestern United States. With a population of 2,746,388 in the 2020 census, it is the third-most populous city in the United States after New York City and Los Angeles. As the seat of Cook County, the second-most populous county in the U.S., Chicago is the center of the Chicago metropolitan area, which is often colloquially called "Chicagoland".
Located on the shore of Lake Michigan, Chicago was incorporated as a city in 1837 near a portage between the Great Lakes and the Mississippi River watershed. It grew rapidly in the mid-19th century. In 1871, the Great Chicago Fire destroyed several square miles and left more than 100,000 homeless, but Chicago's population continued to grow. Chicago made noted contributions to urban planning and architecture, such as the Chicago School, the development of the City Beautiful Movement, and the steel-framed skyscraper.
Chicago is an international hub for finance, culture, commerce, industry, education, technology, telecommunications, and transportation. It has the largest and most diverse derivatives market in the world, generating 20% of all volume in commodities and financial futures alone. O'Hare International Airport is routinely ranked among the world's top six busiest airports by passenger traffic, and the region is also the nation's railroad hub. The Chicago area has one of the highest gross domestic products (GDP) of any urban region in the world, generating $689 billion in 2018. Chicago's economy is diverse, with no single industry employing more than 14% of the workforce.
Chicago is a major tourist destination. Chicago's culture has contributed much to the visual arts, literature, film, theater, comedy (especially improvisational comedy), food, dance, and music (particularly jazz, blues, soul, hip-hop, gospel, and electronic dance music, including house music). Chicago is home to the Chicago Symphony Orchestra and the Lyric Opera of Chicago, while the Art Institute of Chicago provides an influential visual arts museum and art school. The Chicago area also hosts the University of Chicago, Northwestern University, and the University of Illinois Chicago, among other institutions of learning. Chicago has professional sports teams in each of the major professional leagues, including two Major League Baseball teams.
In the mid-18th century, the area was inhabited by the Potawatomi, an indigenous tribe who had succeeded the Miami and Sauk and Fox peoples in this region.
The first known permanent settler in Chicago was trader Jean Baptiste Point du Sable. Du Sable was of African descent, perhaps born in the French colony of Saint-Domingue (Haiti), and established the settlement in the 1780s. He is commonly known as the "Founder of Chicago."
In 1795, following the victory of the new United States in the Northwest Indian War, an area that was to be part of Chicago was turned over to the U.S. for a military post by native tribes in accordance with the Treaty of Greenville. In 1803, the U.S. Army constructed Fort Dearborn, which was destroyed during the War of 1812 in the Battle of Fort Dearborn by the Potawatomi before being later rebuilt.
After the War of 1812, the Ottawa, Ojibwe, and Potawatomi tribes ceded additional land to the United States in the 1816 Treaty of St. Louis. The Potawatomi were forcibly removed from their land after the 1833 Treaty of Chicago and sent west of the Mississippi River as part of the federal policy of Indian removal.
On August 12, 1833, the Town of Chicago was organized with a population of about 200. Within seven years it grew to more than 6,000 people. On June 15, 1835, the first public land sales began with Edmund Dick Taylor as Receiver of Public Monies. The City of Chicago was incorporated on Saturday, March 4, 1837, and for several decades was the world's fastest-growing city.
As the site of the Chicago Portage, the city became an important transportation hub between the eastern and western United States. Chicago's first railway, Galena and Chicago Union Railroad, and the Illinois and Michigan Canal opened in 1848. The canal allowed steamboats and sailing ships on the Great Lakes to connect to the Mississippi River.
A flourishing economy brought residents from rural communities and immigrants from abroad. Manufacturing and retail and finance sectors became dominant, influencing the American economy. The Chicago Board of Trade (established 1848) listed the first-ever standardized "exchange-traded" forward contracts, which were called futures contracts.
In the 1850s, Chicago gained national political prominence as the home of Senator Stephen Douglas, the champion of the Kansas–Nebraska Act and the "popular sovereignty" approach to the issue of the spread of slavery. These issues also helped propel another Illinoisan, Abraham Lincoln, to the national stage. Lincoln was nominated in Chicago for U.S. president at the 1860 Republican National Convention, which was held in a purpose-built auditorium called the Wigwam. He defeated Douglas in the general election, and this set the stage for the American Civil War.
To accommodate rapid population growth and demand for better sanitation, the city improved its infrastructure. In February 1856, Chicago's Common Council approved Chesbrough's plan to build the United States' first comprehensive sewerage system. The project raised much of central Chicago to a new grade with the use of jackscrews for raising buildings. While elevating Chicago, and at first improving the city's health, the untreated sewage and industrial waste now flowed into the Chicago River, and subsequently into Lake Michigan, polluting the city's primary freshwater source.
The city responded by tunneling two miles (3.2 km) out into Lake Michigan to newly built water cribs. In 1900, the problem of sewage contamination was largely resolved when the city completed a major engineering feat. It reversed the flow of the Chicago River so that the water flowed away from Lake Michigan rather than into it. This project began with the construction and improvement of the Illinois and Michigan Canal, and was completed with the Chicago Sanitary and Ship Canal that connects to the Illinois River, which flows into the Mississippi River.
In 1871, the Great Chicago Fire destroyed an area about 4 miles (6.4 km) long and 1-mile (1.6 km) wide, a large section of the city at the time. Much of the city, including railroads and stockyards, survived intact, and from the ruins of the previous wooden structures arose more modern constructions of steel and stone. These set a precedent for worldwide construction. During its rebuilding period, Chicago constructed the world's first skyscraper in 1885, using steel-skeleton construction.
The city grew significantly in size and population by incorporating many neighboring townships between 1851 and 1920, with the largest annexation happening in 1889, with five townships joining the city, including the Hyde Park Township, which now comprises most of the South Side of Chicago and the far southeast of Chicago, and the Jefferson Township, which now makes up most of Chicago's Northwest Side. The desire to join the city was driven by municipal services that the city could provide its residents.
Chicago's flourishing economy attracted huge numbers of new immigrants from Europe and migrants from the Eastern United States. Of the total population in 1900, more than 77% were either foreign-born or born in the United States of foreign parentage. Germans, Irish, Poles, Swedes, and Czechs made up nearly two-thirds of the foreign-born population (by 1900, whites were 98.1% of the city's population).
Labor conflicts followed the industrial boom and the rapid expansion of the labor pool, including the Haymarket affair on May 4, 1886, and in 1894 the Pullman Strike. Anarchist and socialist groups played prominent roles in creating very large and highly organized labor actions. Concern for social problems among Chicago's immigrant poor led Jane Addams and Ellen Gates Starr to found Hull House in 1889. Programs that were developed there became a model for the new field of social work.
During the 1870s and 1880s, Chicago attained national stature as the leader in the movement to improve public health. City laws and later, state laws that upgraded standards for the medical profession and fought urban epidemics of cholera, smallpox, and yellow fever were both passed and enforced. These laws became templates for public health reform in other cities and states.
The city established many large, well-landscaped municipal parks, which also included public sanitation facilities. The chief advocate for improving public health in Chicago was John H. Rauch, M.D. Rauch established a plan for Chicago's park system in 1866. He created Lincoln Park by closing a cemetery filled with shallow graves, and in 1867, in response to an outbreak of cholera he helped establish a new Chicago Board of Health. Ten years later, he became the secretary and then the president of the first Illinois State Board of Health, which carried out most of its activities in Chicago.
In the 1800s, Chicago became the nation's railroad hub, and by 1910 over 20 railroads operated passenger service out of six different downtown terminals. In 1883, Chicago's railway managers needed a general time convention, so they developed the standardized system of North American time zones. This system for telling time spread throughout the continent.
In 1893, Chicago hosted the World's Columbian Exposition on former marshland at the present location of Jackson Park. The Exposition drew 27.5 million visitors, and is considered the most influential world's fair in history. The University of Chicago, formerly at another location, moved to the same South Side location in 1892. The term "midway" for a fair or carnival referred originally to the Midway Plaisance, a strip of park land that still runs through the University of Chicago campus and connects the Washington and Jackson Parks.
During World War I and the 1920s there was a major expansion in industry. The availability of jobs attracted African Americans from the Southern United States. Between 1910 and 1930, the African American population of Chicago increased dramatically, from 44,103 to 233,903. This Great Migration had an immense cultural impact, called the Chicago Black Renaissance, part of the New Negro Movement, in art, literature, and music. Continuing racial tensions and violence, such as the Chicago race riot of 1919, also occurred.
The ratification of the 18th amendment to the Constitution in 1919 made the production and sale (including exportation) of alcoholic beverages illegal in the United States. This ushered in the beginning of what is known as the gangster era, a time that roughly spans from 1919 until 1933 when Prohibition was repealed. The 1920s saw gangsters, including Al Capone, Dion O'Banion, Bugs Moran and Tony Accardo battle law enforcement and each other on the streets of Chicago during the Prohibition era. Chicago was the location of the infamous St. Valentine's Day Massacre in 1929, when Al Capone sent men to gun down members of a rival gang, North Side, led by Bugs Moran.
Chicago was the first American city to have a homosexual-rights organization. The organization, formed in 1924, was called the Society for Human Rights. It produced the first American publication for homosexuals, Friendship and Freedom. Police and political pressure caused the organization to disband.
The Great Depression brought unprecedented suffering to Chicago, in no small part due to the city's heavy reliance on heavy industry. Notably, industrial areas on the south side and neighborhoods lining both branches of the Chicago River were devastated; by 1933 over 50% of industrial jobs in the city had been lost, and unemployment rates amongst blacks and Mexicans in the city were over 40%. The Republican political machine in Chicago was utterly destroyed by the economic crisis, and every mayor since 1931 has been a Democrat.
From 1928 to 1933, the city witnessed a tax revolt, and the city was unable to meet payroll or provide relief efforts. The fiscal crisis was resolved by 1933, and at the same time, federal relief funding began to flow into Chicago. Chicago was also a hotbed of labor activism, with Unemployed Councils contributing heavily in the early depression to create solidarity for the poor and demand relief; these organizations were created by socialist and communist groups. By 1935 the Workers Alliance of America begun organizing the poor, workers, the unemployed. In the spring of 1937 Republic Steel Works witnessed the Memorial Day massacre of 1937 in the neighborhood of East Side.
In 1933, Chicago Mayor Anton Cermak was fatally wounded in Miami, Florida, during a failed assassination attempt on President-elect Franklin D. Roosevelt. In 1933 and 1934, the city celebrated its centennial by hosting the Century of Progress International Exposition World's Fair. The theme of the fair was technological innovation over the century since Chicago's founding.
During World War II, the city of Chicago alone produced more steel than the United Kingdom every year from 1939 – 1945, and more than Nazi Germany from 1943 – 1945.
The Great Migration, which had been on pause due to the Depression, resumed at an even faster pace in the second wave, as hundreds of thousands of blacks from the South arrived in the city to work in the steel mills, railroads, and shipping yards.
On December 2, 1942, physicist Enrico Fermi conducted the world's first controlled nuclear reaction at the University of Chicago as part of the top-secret Manhattan Project. This led to the creation of the atomic bomb by the United States, which it used in World War II in 1945.
Mayor Richard J. Daley, a Democrat, was elected in 1955, in the era of machine politics. In 1956, the city conducted its last major expansion when it annexed the land under O'Hare airport, including a small portion of DuPage County.
By the 1960s, white residents in several neighborhoods left the city for the suburban areas – in many American cities, a process known as white flight – as Blacks continued to move beyond the Black Belt. While home loan discriminatory redlining against blacks continued, the real estate industry practiced what became known as blockbusting, completely changing the racial composition of whole neighborhoods. Structural changes in industry, such as globalization and job outsourcing, caused heavy job losses for lower-skilled workers. At its peak during the 1960s, some 250,000 workers were employed in the steel industry in Chicago, but the steel crisis of the 1970s and 1980s reduced this number to just 28,000 in 2015. In 1966, Martin Luther King Jr. and Albert Raby led the Chicago Freedom Movement, which culminated in agreements between Mayor Richard J. Daley and the movement leaders.
Two years later, the city hosted the tumultuous 1968 Democratic National Convention, which featured physical confrontations both inside and outside the convention hall, with anti-war protesters, journalists and bystanders being beaten by police. Major construction projects, including the Sears Tower (now known as the Willis Tower, which in 1974 became the world's tallest building), University of Illinois at Chicago, McCormick Place, and O'Hare International Airport, were undertaken during Richard J. Daley's tenure. In 1979, Jane Byrne, the city's first female mayor, was elected. She was notable for temporarily moving into the crime-ridden Cabrini-Green housing project and for leading Chicago's school system out of a financial crisis.
In 1983, Harold Washington became the first black mayor of Chicago. Washington's first term in office directed attention to poor and previously neglected minority neighborhoods. He was re‑elected in 1987 but died of a heart attack soon after. Washington was succeeded by 6th ward alderperson Eugene Sawyer, who was elected by the Chicago City Council and served until a special election.
Richard M. Daley, son of Richard J. Daley, was elected in 1989. His accomplishments included improvements to parks and creating incentives for sustainable development, as well as closing Meigs Field in the middle of the night and destroying the runways. After successfully running for re-election five times, and becoming Chicago's longest-serving mayor, Richard M. Daley declined to run for a seventh term.
In 1992, a construction accident near the Kinzie Street Bridge produced a breach connecting the Chicago River to a tunnel below, which was part of an abandoned freight tunnel system extending throughout the downtown Loop district. The tunnels filled with 250 million US gallons (1,000,000 m3) of water, affecting buildings throughout the district and forcing a shutdown of electrical power. The area was shut down for three days and some buildings did not reopen for weeks; losses were estimated at $1.95 billion.
On February 23, 2011, Rahm Emanuel, a former White House Chief of Staff and member of the House of Representatives, won the mayoral election. Emanuel was sworn in as mayor on May 16, 2011, and won re-election in 2015. Lori Lightfoot, the city's first African American woman mayor and its first openly LGBTQ mayor, was elected to succeed Emanuel as mayor in 2019. All three city-wide elective offices were held by women (and women of color) for the first time in Chicago history: in addition to Lightfoot, the city clerk was Anna Valencia and the city treasurer was Melissa Conyears-Ervin.
On May 15, 2023, Brandon Johnson assumed office as the 57th mayor of Chicago.
Illinois is a state in the Midwestern region of the United States. It borders Great Lakes to its northeast, the Mississippi River to its west, and the Wabash and Ohio rivers to its south. Its largest metropolitan areas are Chicago and the Metro East region of Greater St. Louis. Other metropolitan areas include Peoria and Rockford, as well as Springfield, its capital, and Champaign-Urbana, home to the main campus of the state's flagship university. Of the fifty U.S. states, Illinois has the fifth-largest gross domestic product (GDP), the sixth-largest population, and the 25th-largest land area.
Illinois has a highly diverse economy, with the global city of Chicago in the northeast, major industrial and agricultural hubs in the north and center, and natural resources such as coal, timber, and petroleum in the south. Owing to its central location and favorable geography, the state is a major transportation hub: the Port of Chicago has access to the Atlantic Ocean through the Great Lakes and Saint Lawrence Seaway and to the Gulf of Mexico from the Mississippi River via the Illinois Waterway. Chicago has been the nation's railroad hub since the 1860s, and its O'Hare International Airport has been among the world's busiest airports for decades. Illinois has long been considered a microcosm of the United States and a bellwether in American culture, exemplified by the phrase Will it play in Peoria?.
Present-day Illinois was inhabited by various indigenous cultures for thousands of years, including the advanced civilization centered in the Cahokia region. The French were the first Europeans to arrive, settling near the Mississippi and Illinois River in the 17th century in the region they called Illinois Country, as part of the sprawling colony of New France. Following U.S. independence in 1783, American settlers began arriving from Kentucky via the Ohio River, and the population grew from south to north. Illinois was part of the United States' oldest territory, the Northwest Territory, and in 1818 it achieved statehood. The Erie Canal brought increased commercial activity in the Great Lakes, and the small settlement of Chicago became one of the fastest growing cities in the world, benefiting from its location as one of the few natural harbors in southwestern Lake Michigan. The invention of the self-scouring steel plow by Illinoisan John Deere turned the state's rich prairie into some of the world's most productive and valuable farmland, attracting immigrant farmers from Germany and Sweden. In the mid-19th century, the Illinois and Michigan Canal and a sprawling railroad network greatly facilitated trade, commerce, and settlement, making the state a transportation hub for the nation.
By 1900, the growth of industrial jobs in the northern cities and coal mining in the central and southern areas attracted immigrants from Eastern and Southern Europe. Illinois became one of America's most industrialized states and remains a major manufacturing center. The Great Migration from the South established a large community of African Americans, particularly in Chicago, who founded the city's famous jazz and blues cultures. Chicago became a leading cultural, economic, and population center and is today one of the world's major commercial centers; its metropolitan area, informally referred to as Chicagoland, holds about 65% of the state's 12.8 million residents.
Two World Heritage Sites are in Illinois, the ancient Cahokia Mounds, and part of the Wright architecture site. Major centers of learning include the University of Chicago, University of Illinois, and Northwestern University. A wide variety of protected areas seek to conserve Illinois' natural and cultural resources. Historically, three U.S. presidents have been elected while residents of Illinois: Abraham Lincoln, Ulysses S. Grant, and Barack Obama; additionally, Ronald Reagan was born and raised in the state. Illinois honors Lincoln with its official state slogan Land of Lincoln. The state is the site of the Abraham Lincoln Presidential Library and Museum in Springfield and the future home of the Barack Obama Presidential Center in Chicago.
Chicago is the most populous city in the U.S. state of Illinois and in the Midwestern United States. With a population of 2,746,388 in the 2020 census, it is the third-most populous city in the United States after New York City and Los Angeles. As the seat of Cook County, the second-most populous county in the U.S., Chicago is the center of the Chicago metropolitan area, which is often colloquially called "Chicagoland".
Located on the shore of Lake Michigan, Chicago was incorporated as a city in 1837 near a portage between the Great Lakes and the Mississippi River watershed. It grew rapidly in the mid-19th century. In 1871, the Great Chicago Fire destroyed several square miles and left more than 100,000 homeless, but Chicago's population continued to grow. Chicago made noted contributions to urban planning and architecture, such as the Chicago School, the development of the City Beautiful Movement, and the steel-framed skyscraper.
Chicago is an international hub for finance, culture, commerce, industry, education, technology, telecommunications, and transportation. It has the largest and most diverse derivatives market in the world, generating 20% of all volume in commodities and financial futures alone. O'Hare International Airport is routinely ranked among the world's top six busiest airports by passenger traffic, and the region is also the nation's railroad hub. The Chicago area has one of the highest gross domestic products (GDP) of any urban region in the world, generating $689 billion in 2018. Chicago's economy is diverse, with no single industry employing more than 14% of the workforce.
Chicago is a major tourist destination. Chicago's culture has contributed much to the visual arts, literature, film, theater, comedy (especially improvisational comedy), food, dance, and music (particularly jazz, blues, soul, hip-hop, gospel, and electronic dance music, including house music). Chicago is home to the Chicago Symphony Orchestra and the Lyric Opera of Chicago, while the Art Institute of Chicago provides an influential visual arts museum and art school. The Chicago area also hosts the University of Chicago, Northwestern University, and the University of Illinois Chicago, among other institutions of learning. Chicago has professional sports teams in each of the major professional leagues, including two Major League Baseball teams.
In the mid-18th century, the area was inhabited by the Potawatomi, an indigenous tribe who had succeeded the Miami and Sauk and Fox peoples in this region.
The first known permanent settler in Chicago was trader Jean Baptiste Point du Sable. Du Sable was of African descent, perhaps born in the French colony of Saint-Domingue (Haiti), and established the settlement in the 1780s. He is commonly known as the "Founder of Chicago."
In 1795, following the victory of the new United States in the Northwest Indian War, an area that was to be part of Chicago was turned over to the U.S. for a military post by native tribes in accordance with the Treaty of Greenville. In 1803, the U.S. Army constructed Fort Dearborn, which was destroyed during the War of 1812 in the Battle of Fort Dearborn by the Potawatomi before being later rebuilt.
After the War of 1812, the Ottawa, Ojibwe, and Potawatomi tribes ceded additional land to the United States in the 1816 Treaty of St. Louis. The Potawatomi were forcibly removed from their land after the 1833 Treaty of Chicago and sent west of the Mississippi River as part of the federal policy of Indian removal.
On August 12, 1833, the Town of Chicago was organized with a population of about 200. Within seven years it grew to more than 6,000 people. On June 15, 1835, the first public land sales began with Edmund Dick Taylor as Receiver of Public Monies. The City of Chicago was incorporated on Saturday, March 4, 1837, and for several decades was the world's fastest-growing city.
As the site of the Chicago Portage, the city became an important transportation hub between the eastern and western United States. Chicago's first railway, Galena and Chicago Union Railroad, and the Illinois and Michigan Canal opened in 1848. The canal allowed steamboats and sailing ships on the Great Lakes to connect to the Mississippi River.
A flourishing economy brought residents from rural communities and immigrants from abroad. Manufacturing and retail and finance sectors became dominant, influencing the American economy. The Chicago Board of Trade (established 1848) listed the first-ever standardized "exchange-traded" forward contracts, which were called futures contracts.
In the 1850s, Chicago gained national political prominence as the home of Senator Stephen Douglas, the champion of the Kansas–Nebraska Act and the "popular sovereignty" approach to the issue of the spread of slavery. These issues also helped propel another Illinoisan, Abraham Lincoln, to the national stage. Lincoln was nominated in Chicago for U.S. president at the 1860 Republican National Convention, which was held in a purpose-built auditorium called the Wigwam. He defeated Douglas in the general election, and this set the stage for the American Civil War.
To accommodate rapid population growth and demand for better sanitation, the city improved its infrastructure. In February 1856, Chicago's Common Council approved Chesbrough's plan to build the United States' first comprehensive sewerage system. The project raised much of central Chicago to a new grade with the use of jackscrews for raising buildings. While elevating Chicago, and at first improving the city's health, the untreated sewage and industrial waste now flowed into the Chicago River, and subsequently into Lake Michigan, polluting the city's primary freshwater source.
The city responded by tunneling two miles (3.2 km) out into Lake Michigan to newly built water cribs. In 1900, the problem of sewage contamination was largely resolved when the city completed a major engineering feat. It reversed the flow of the Chicago River so that the water flowed away from Lake Michigan rather than into it. This project began with the construction and improvement of the Illinois and Michigan Canal, and was completed with the Chicago Sanitary and Ship Canal that connects to the Illinois River, which flows into the Mississippi River.
In 1871, the Great Chicago Fire destroyed an area about 4 miles (6.4 km) long and 1-mile (1.6 km) wide, a large section of the city at the time. Much of the city, including railroads and stockyards, survived intact, and from the ruins of the previous wooden structures arose more modern constructions of steel and stone. These set a precedent for worldwide construction. During its rebuilding period, Chicago constructed the world's first skyscraper in 1885, using steel-skeleton construction.
The city grew significantly in size and population by incorporating many neighboring townships between 1851 and 1920, with the largest annexation happening in 1889, with five townships joining the city, including the Hyde Park Township, which now comprises most of the South Side of Chicago and the far southeast of Chicago, and the Jefferson Township, which now makes up most of Chicago's Northwest Side. The desire to join the city was driven by municipal services that the city could provide its residents.
Chicago's flourishing economy attracted huge numbers of new immigrants from Europe and migrants from the Eastern United States. Of the total population in 1900, more than 77% were either foreign-born or born in the United States of foreign parentage. Germans, Irish, Poles, Swedes, and Czechs made up nearly two-thirds of the foreign-born population (by 1900, whites were 98.1% of the city's population).
Labor conflicts followed the industrial boom and the rapid expansion of the labor pool, including the Haymarket affair on May 4, 1886, and in 1894 the Pullman Strike. Anarchist and socialist groups played prominent roles in creating very large and highly organized labor actions. Concern for social problems among Chicago's immigrant poor led Jane Addams and Ellen Gates Starr to found Hull House in 1889. Programs that were developed there became a model for the new field of social work.
During the 1870s and 1880s, Chicago attained national stature as the leader in the movement to improve public health. City laws and later, state laws that upgraded standards for the medical profession and fought urban epidemics of cholera, smallpox, and yellow fever were both passed and enforced. These laws became templates for public health reform in other cities and states.
The city established many large, well-landscaped municipal parks, which also included public sanitation facilities. The chief advocate for improving public health in Chicago was John H. Rauch, M.D. Rauch established a plan for Chicago's park system in 1866. He created Lincoln Park by closing a cemetery filled with shallow graves, and in 1867, in response to an outbreak of cholera he helped establish a new Chicago Board of Health. Ten years later, he became the secretary and then the president of the first Illinois State Board of Health, which carried out most of its activities in Chicago.
In the 1800s, Chicago became the nation's railroad hub, and by 1910 over 20 railroads operated passenger service out of six different downtown terminals. In 1883, Chicago's railway managers needed a general time convention, so they developed the standardized system of North American time zones. This system for telling time spread throughout the continent.
In 1893, Chicago hosted the World's Columbian Exposition on former marshland at the present location of Jackson Park. The Exposition drew 27.5 million visitors, and is considered the most influential world's fair in history. The University of Chicago, formerly at another location, moved to the same South Side location in 1892. The term "midway" for a fair or carnival referred originally to the Midway Plaisance, a strip of park land that still runs through the University of Chicago campus and connects the Washington and Jackson Parks.
During World War I and the 1920s there was a major expansion in industry. The availability of jobs attracted African Americans from the Southern United States. Between 1910 and 1930, the African American population of Chicago increased dramatically, from 44,103 to 233,903. This Great Migration had an immense cultural impact, called the Chicago Black Renaissance, part of the New Negro Movement, in art, literature, and music. Continuing racial tensions and violence, such as the Chicago race riot of 1919, also occurred.
The ratification of the 18th amendment to the Constitution in 1919 made the production and sale (including exportation) of alcoholic beverages illegal in the United States. This ushered in the beginning of what is known as the gangster era, a time that roughly spans from 1919 until 1933 when Prohibition was repealed. The 1920s saw gangsters, including Al Capone, Dion O'Banion, Bugs Moran and Tony Accardo battle law enforcement and each other on the streets of Chicago during the Prohibition era. Chicago was the location of the infamous St. Valentine's Day Massacre in 1929, when Al Capone sent men to gun down members of a rival gang, North Side, led by Bugs Moran.
Chicago was the first American city to have a homosexual-rights organization. The organization, formed in 1924, was called the Society for Human Rights. It produced the first American publication for homosexuals, Friendship and Freedom. Police and political pressure caused the organization to disband.
The Great Depression brought unprecedented suffering to Chicago, in no small part due to the city's heavy reliance on heavy industry. Notably, industrial areas on the south side and neighborhoods lining both branches of the Chicago River were devastated; by 1933 over 50% of industrial jobs in the city had been lost, and unemployment rates amongst blacks and Mexicans in the city were over 40%. The Republican political machine in Chicago was utterly destroyed by the economic crisis, and every mayor since 1931 has been a Democrat.
From 1928 to 1933, the city witnessed a tax revolt, and the city was unable to meet payroll or provide relief efforts. The fiscal crisis was resolved by 1933, and at the same time, federal relief funding began to flow into Chicago. Chicago was also a hotbed of labor activism, with Unemployed Councils contributing heavily in the early depression to create solidarity for the poor and demand relief; these organizations were created by socialist and communist groups. By 1935 the Workers Alliance of America begun organizing the poor, workers, the unemployed. In the spring of 1937 Republic Steel Works witnessed the Memorial Day massacre of 1937 in the neighborhood of East Side.
In 1933, Chicago Mayor Anton Cermak was fatally wounded in Miami, Florida, during a failed assassination attempt on President-elect Franklin D. Roosevelt. In 1933 and 1934, the city celebrated its centennial by hosting the Century of Progress International Exposition World's Fair. The theme of the fair was technological innovation over the century since Chicago's founding.
During World War II, the city of Chicago alone produced more steel than the United Kingdom every year from 1939 – 1945, and more than Nazi Germany from 1943 – 1945.
The Great Migration, which had been on pause due to the Depression, resumed at an even faster pace in the second wave, as hundreds of thousands of blacks from the South arrived in the city to work in the steel mills, railroads, and shipping yards.
On December 2, 1942, physicist Enrico Fermi conducted the world's first controlled nuclear reaction at the University of Chicago as part of the top-secret Manhattan Project. This led to the creation of the atomic bomb by the United States, which it used in World War II in 1945.
Mayor Richard J. Daley, a Democrat, was elected in 1955, in the era of machine politics. In 1956, the city conducted its last major expansion when it annexed the land under O'Hare airport, including a small portion of DuPage County.
By the 1960s, white residents in several neighborhoods left the city for the suburban areas – in many American cities, a process known as white flight – as Blacks continued to move beyond the Black Belt. While home loan discriminatory redlining against blacks continued, the real estate industry practiced what became known as blockbusting, completely changing the racial composition of whole neighborhoods. Structural changes in industry, such as globalization and job outsourcing, caused heavy job losses for lower-skilled workers. At its peak during the 1960s, some 250,000 workers were employed in the steel industry in Chicago, but the steel crisis of the 1970s and 1980s reduced this number to just 28,000 in 2015. In 1966, Martin Luther King Jr. and Albert Raby led the Chicago Freedom Movement, which culminated in agreements between Mayor Richard J. Daley and the movement leaders.
Two years later, the city hosted the tumultuous 1968 Democratic National Convention, which featured physical confrontations both inside and outside the convention hall, with anti-war protesters, journalists and bystanders being beaten by police. Major construction projects, including the Sears Tower (now known as the Willis Tower, which in 1974 became the world's tallest building), University of Illinois at Chicago, McCormick Place, and O'Hare International Airport, were undertaken during Richard J. Daley's tenure. In 1979, Jane Byrne, the city's first female mayor, was elected. She was notable for temporarily moving into the crime-ridden Cabrini-Green housing project and for leading Chicago's school system out of a financial crisis.
In 1983, Harold Washington became the first black mayor of Chicago. Washington's first term in office directed attention to poor and previously neglected minority neighborhoods. He was re‑elected in 1987 but died of a heart attack soon after. Washington was succeeded by 6th ward alderperson Eugene Sawyer, who was elected by the Chicago City Council and served until a special election.
Richard M. Daley, son of Richard J. Daley, was elected in 1989. His accomplishments included improvements to parks and creating incentives for sustainable development, as well as closing Meigs Field in the middle of the night and destroying the runways. After successfully running for re-election five times, and becoming Chicago's longest-serving mayor, Richard M. Daley declined to run for a seventh term.
In 1992, a construction accident near the Kinzie Street Bridge produced a breach connecting the Chicago River to a tunnel below, which was part of an abandoned freight tunnel system extending throughout the downtown Loop district. The tunnels filled with 250 million US gallons (1,000,000 m3) of water, affecting buildings throughout the district and forcing a shutdown of electrical power. The area was shut down for three days and some buildings did not reopen for weeks; losses were estimated at $1.95 billion.
On February 23, 2011, Rahm Emanuel, a former White House Chief of Staff and member of the House of Representatives, won the mayoral election. Emanuel was sworn in as mayor on May 16, 2011, and won re-election in 2015. Lori Lightfoot, the city's first African American woman mayor and its first openly LGBTQ mayor, was elected to succeed Emanuel as mayor in 2019. All three city-wide elective offices were held by women (and women of color) for the first time in Chicago history: in addition to Lightfoot, the city clerk was Anna Valencia and the city treasurer was Melissa Conyears-Ervin.
On May 15, 2023, Brandon Johnson assumed office as the 57th mayor of Chicago.
Illinois is a state in the Midwestern region of the United States. It borders Great Lakes to its northeast, the Mississippi River to its west, and the Wabash and Ohio rivers to its south. Its largest metropolitan areas are Chicago and the Metro East region of Greater St. Louis. Other metropolitan areas include Peoria and Rockford, as well as Springfield, its capital, and Champaign-Urbana, home to the main campus of the state's flagship university. Of the fifty U.S. states, Illinois has the fifth-largest gross domestic product (GDP), the sixth-largest population, and the 25th-largest land area.
Illinois has a highly diverse economy, with the global city of Chicago in the northeast, major industrial and agricultural hubs in the north and center, and natural resources such as coal, timber, and petroleum in the south. Owing to its central location and favorable geography, the state is a major transportation hub: the Port of Chicago has access to the Atlantic Ocean through the Great Lakes and Saint Lawrence Seaway and to the Gulf of Mexico from the Mississippi River via the Illinois Waterway. Chicago has been the nation's railroad hub since the 1860s, and its O'Hare International Airport has been among the world's busiest airports for decades. Illinois has long been considered a microcosm of the United States and a bellwether in American culture, exemplified by the phrase Will it play in Peoria?.
Present-day Illinois was inhabited by various indigenous cultures for thousands of years, including the advanced civilization centered in the Cahokia region. The French were the first Europeans to arrive, settling near the Mississippi and Illinois River in the 17th century in the region they called Illinois Country, as part of the sprawling colony of New France. Following U.S. independence in 1783, American settlers began arriving from Kentucky via the Ohio River, and the population grew from south to north. Illinois was part of the United States' oldest territory, the Northwest Territory, and in 1818 it achieved statehood. The Erie Canal brought increased commercial activity in the Great Lakes, and the small settlement of Chicago became one of the fastest growing cities in the world, benefiting from its location as one of the few natural harbors in southwestern Lake Michigan. The invention of the self-scouring steel plow by Illinoisan John Deere turned the state's rich prairie into some of the world's most productive and valuable farmland, attracting immigrant farmers from Germany and Sweden. In the mid-19th century, the Illinois and Michigan Canal and a sprawling railroad network greatly facilitated trade, commerce, and settlement, making the state a transportation hub for the nation.
By 1900, the growth of industrial jobs in the northern cities and coal mining in the central and southern areas attracted immigrants from Eastern and Southern Europe. Illinois became one of America's most industrialized states and remains a major manufacturing center. The Great Migration from the South established a large community of African Americans, particularly in Chicago, who founded the city's famous jazz and blues cultures. Chicago became a leading cultural, economic, and population center and is today one of the world's major commercial centers; its metropolitan area, informally referred to as Chicagoland, holds about 65% of the state's 12.8 million residents.
Two World Heritage Sites are in Illinois, the ancient Cahokia Mounds, and part of the Wright architecture site. Major centers of learning include the University of Chicago, University of Illinois, and Northwestern University. A wide variety of protected areas seek to conserve Illinois' natural and cultural resources. Historically, three U.S. presidents have been elected while residents of Illinois: Abraham Lincoln, Ulysses S. Grant, and Barack Obama; additionally, Ronald Reagan was born and raised in the state. Illinois honors Lincoln with its official state slogan Land of Lincoln. The state is the site of the Abraham Lincoln Presidential Library and Museum in Springfield and the future home of the Barack Obama Presidential Center in Chicago.

Technology company
From Wikipedia, the free encyclopedia
Jump to navigationJump to search
A technology company (or tech company) is an electronics-based technological company, including, for example, business relating to digital electronics, software, and internet-related services, such as e-commerce services.[1][2][3]
Details
According to Fortune, as of 2020, the ten largest technology companies by revenue are: Apple Inc., Samsung, Foxconn, Alphabet Inc., Microsoft, Huawei, Dell Technologies, Hitachi, IBM, and Sony.[4] Amazon has higher revenue than Apple, but is classified by Fortune in the retail sector.[5] The most profitable listed in 2020 are Apple Inc., Microsoft, Alphabet Inc., Intel, Meta Platforms, Samsung, and Tencent.[4]
Apple Inc., Alphabet Inc. (owner of Google), Meta Platforms (owner of Facebook), Microsoft, and Amazon.com, Inc. are often referred to as the Big Five multinational technology companies based in the United States. These five technology companies dominate major functions, e-commerce channels, and information of the entire Internet ecosystem. As of 2017, the Big Five had a combined valuation of over $3.3 trillion and make up more than 40 percent of the value of the Nasdaq-100 index.[6]
Many large tech companies have a reputation for innovation, spending large sums of money annually on research and development. According to PwC's 2017 Global Innovation 1000 ranking, tech companies made up nine of the 20 most innovative companies in the world, with the top R&D spender (as measured by expenditure) being Amazon, followed by Alphabet Inc., and then Intel.[7]
As a result of numerous influential tech companies and tech startups opening offices in proximity to one another, a number of technology districts have developed in various areas across the globe.[8] These include: Silicon Valley in the San Francisco Bay Area, Silicon Wadi in Israel, Silicon Docks in Dublin, Silicon Hills in Austin, Tech City in London; Digital Media City in Seoul, Zhongguancun in Beijing, Cyberjaya in Malaysia and Cyberabad in Hyderabad.
A startup or start-up is a company or project undertaken by an entrepreneur to seek, develop, and validate a scalable business model.[1][2] While entrepreneurship refers to all new businesses, including self-employment and businesses that never intend to become registered, startups refer to new businesses that intend to grow large beyond the solo founder.[3] At the beginning, startups face high uncertainty[4] and have high rates of failure, but a minority of them do go on to be successful and influential.[5]
Actions
Startups typically begin by a founder (solo-founder) or co-founders who have a way to solve a problem. The founder of a startup will begin market validation by problem interview, solution interview, and building a minimum viable product (MVP), i.e. a prototype, to develop and validate their business models. The startup process can take a long period of time (by some estimates, three years or longer), and hence sustaining effort is required. Over the long term, sustaining effort is especially challenging because of the high failure rates and uncertain outcomes.[6] Having a business plan in place outlines what to do and how to plan and achieve an idea in the future. Typically, these plans outline the first 3 to 5 years of your business strategy. [7]
Design principles
Models behind startups presenting as ventures are usually associated with design science. Design science uses design principles considered to be a coherent set of normative ideas and propositions to design and construct the company's backbone.[8] For example, one of the initial design principles is "affordable loss".[9]
Heuristics and biases in startup actions
Because of the lack of information, high uncertainty, the need to make decisions quickly, founders of startups use many heuristics and exhibit biases in their startup actions. Biases and heuristics are parts of our cognitive toolboxes in the decision-making process. They help us decide quickly as possible under uncertainty but sometimes become erroneous and fallacious.[10]
Entrepreneurs often become overconfident about their startups and their influence on an outcome (case of the illusion of control). Entrepreneurs tend to believe they have more degree of control over events, discounting the role of luck. Below are some of the most critical decision biases of entrepreneurs to start up a new business.[10]
Overconfidence: Perceive a subjective certainty higher than the objective accuracy.
Illusion of control: Overemphasize how much skills, instead of chance, improve performance.
The law of small numbers: Reach conclusions about a larger population using a limited sample.
Availability bias: Make judgments about the probability of events based on how easy it is to think of examples.
Escalation of commitment: Persist unduly with unsuccessful initiatives or courses of action.
Startups use several action principles to generate evidence as quickly as possible to reduce the downside effect of decision biases such as an escalation of commitment, overconfidence, and the illusion of control.
Mentoring
Many entrepreneurs seek feedback from mentors in creating their startups. Mentors guide founders and impart entrepreneurial skills and may increase the self-efficacy of nascent entrepreneurs.[11] Mentoring offers direction for entrepreneurs to enhance their knowledge of how to sustain their assets relating to their status and identity and strengthen their real-time skills.[12]
Principles
There are many principles in creating a startup. Some of the principles are listed below.
Lean startup
Lean startup is a clear set of principles to create and design startups under limited resources and tremendous uncertainty to build their ventures more flexibly and at a lower cost. It is based on the idea that entrepreneurs can make their implicit assumptions about how their venture works explicit and empirically testing it.[13] The empirical test is to de/validate these assumptions and to get an engaged understanding of the business model of the new ventures, and in doing so, the new ventures are created iteratively in a build–measure–learn loop. Hence, lean startup is a set of principles for entrepreneurial learning and business model design. More precisely, it is a set of design principles aimed for iteratively experiential learning under uncertainty in an engaged empirical manner. Typically, lean startup focuses on a few lean principles:
find a problem worth solving, then define a solution
engage early adopters for market validation
continually test with smaller, faster iterations
build a function, measure customer response, and verify/refute the idea
evidence-based decisions on when to "pivot" by changing your plan's course
maximize the efforts for speed, learning, and focus
Market validation
A key principle of startup is to validate the market need before providing a customer-centric product or service to avoid business ideas with weak demand.[14] Market validation can be done in a number of ways, including surveys, cold calling, email responses, word of mouth or through sample research.[15]
Design thinking
Design thinking is used to understand the customers' need in an engaged manner. Design thinking and customer development can be biased because they do not remove the risk of bias because the same biases will manifest themselves in the sources of information, the type of information sought, and the interpretation of that information.[16] Encouraging people to “consider the opposite” of whatever decision they are about to make tends to reduce biases such as overconfidence, the hindsight bias, and anchoring (Larrick, 2004; Mussweiler, Strack, & Pfeiffer, 2000).
Decision-making under uncertainty
In startups, many decisions are made under uncertainty,[4] and hence a key principle for startups is to be agile and flexible. Founders can embed options to design startups in flexible manners, so that the startups can change easily in future.
Uncertainty can vary within-person (I feel more uncertain this year than last year) and between-person (he feels more uncertain than she does). A study found that when entrepreneurs feel more uncertain, they identify more opportunities (within-person difference), but entrepreneurs who perceive more uncertainties than others do not identify more opportunities than others do (no between-person difference).[4]
Partnering
Startups may form partnerships with other firms to enable their business model to operate.[17] To become attractive to other businesses, startups need to align their internal features, such as management style and products with the market situation. In their 2013 study, Kask and Linton develop two ideal profiles, or also known as configurations or archetypes, for startups that are commercializing inventions. The inheritor profile calls for a management style that is not too entrepreneurial (more conservative) and the startup should have an incremental invention (building on a previous standard). This profile is set out to be more successful (in finding a business partner) in a market that has a dominant design (a clear standard is applied in this market). In contrast to this profile is the originator which has a management style that is highly entrepreneurial and in which a radical invention or a disruptive innovation (totally new standard) is being developed. This profile is set out to be more successful (in finding a business partner) in a market that does not have a dominant design (established standard). New startups should align themselves to one of the profiles when commercializing an invention to be able to find and be attractive to a business partner. By finding a business partner, a startup has greater chances of becoming successful.[18]
Startups usually need many different partners to realize their business idea. The commercialization process is often a bumpy road with iterations and new insights during the process. Hasche and Linton (2018)[19] argue that startups can learn from their relationships with other firms, and even if the relationship ends, the startup will have gained valuable knowledge about how it should move on going forward. When a relationship is failing for a startup it needs to make changes. Three types of changes can be identified according to Hasche and Linton (2018):[19]
Change of business concept for the start up
Change of collaboration constellation (change several relationships)
Change of characteristic of business relationship (with the partner, e.g. from a transactional relationship to more of a collaborative type of relationship)
Entrepreneurial learning
See also: Validated learning
Startups need to learn at a huge speed before running out of resources. Proactive actions (experimentation, searching, etc.) enhance a founder's learning to start a company.[20] To learn effectively, founders often formulate falsifiable hypotheses, build a minimum viable product (MVP), and conduct A/B testing.
Business Model Design
With the key learnings from market validation, design thinking, and lean startup, founders can design a business model. However it's important not to dive into business models too early before there is sufficient learning on market validation. Paul Graham said "What I tell founders is not to sweat the business model too much at first. The most important task at first is to build something people want. If you don’t do that, it won’t matter how clever your business model is."[21]
Founders/entrepreneurs
Main article: Organizational founder
Founders or co-founders are people involved in the initial launch of startup companies. Anyone can be a co-founder, and an existing company can also be a co-founder, but the most common co-founders are founder-CEOs, engineers, hackers, web developers, web designers and others involved in the ground level of a new, often venture. The founder that is responsible for the overall strategy of the startup plays the role of founder-CEOs, much like CEOs in established firms. Startup studios provide an opportunity for founders and team members to grow along with the business they help to build. In order to create forward momentum, founders must ensure that they provide opportunities for their team members to grow and evolve within the company.[22]
The language of securities regulation in the United States considers co-founders to be "promoters" under Regulation D. The U.S. Securities and Exchange Commission definition of "Promoter" includes: (i) Any person who, acting alone or in conjunction with one or more other persons, directly or indirectly takes initiative in founding and organizing the business or enterprise of an issuer;[23] However, not every promoter is a co-founder. In fact, there is no formal, legal definition of what makes somebody a co-founder.[24][25] The right to call oneself a co-founder can be established through an agreement with one's fellow co-founders or with permission of the board of directors, investors, or shareholders of a startup company. When there is no definitive agreement (like shareholders' agreement), disputes about who the co-founders are, can arise.
Self-efficacy
Self-efficacy refers to the confidence an individual has to create a new business or startup. It has a strong relation with startup actions.[26] Entrepreneurs' sense of self-efficacy can play a major role in how they approach goals, tasks, and challenges. Entrepreneurs with high self-efficacy—that is, those who believe they can perform well—are more likely to view difficult tasks as something to be mastered rather than something to be avoided.
Stress
Startups are pressure cookers. Don’t let the casual dress and playful office environment fool you. New enterprises operate under do-or-die conditions. If you do not roll out a useable product or service in a timely fashion, the company will fail. Bye-bye paycheck, hello eviction.
Iman Jalali, chief of staff at ContextMedia[27][unreliable source?]
Entrepreneurs often feel stressed. They have internal and external pressures. Internally, they need to meet deadlines to develop the prototypes and get the product or service ready for market. Externally they are expected to meet milestones of investors and other stakeholders to ensure continued resources from them on the startups.[28] Coping with stress is critical to entrepreneurs because of the stressful nature of start up a new firm under uncertainty. Coping with stress unsuccessfully could lead to emotional exhaustion, and the founders may close or exit the startups.
Emotional exhaustion
Sustaining effort is required as the startup process can take a long period of time, by one estimate, three years or longer (Carter et al., 1996; Reynolds & Miller, 1992). Sustaining effort over the long term is especially challenging because of the high failure rates and uncertain outcomes.[28]
Founder identity and culture
Some startup founders have a more casual or offbeat attitude in their dress, office space and marketing, as compared to executives in established corporations. For example, startup founders in the 2010s wore hoodies, sneakers and other casual clothes to business meetings. Their offices may have recreational facilities in them, such as pool tables, ping pong tables, football tables and pinball machines, which are used to create a fun work environment, stimulate team development and team spirit, and encourage creativity. Some of the casual approaches, such as the use of "flat" organizational structures, in which regular employees can talk with the founders and chief executive officers informally, are done to promote efficiency in the workplace, which is needed to get their business off the ground.[29]
In a 1960 study, Douglas McGregor stressed that punishments and rewards for uniformity in the workplace are not necessary because some people are born with the motivation to work without incentives.[30] Some startups do not use a strict command and control hierarchical structure, with executives, managers, supervisors and employees. Some startups offer employees incentives such as stock options, to increase their "buy in" from the start up (as these employees stand to gain if the company does well). This removal of stressors allows the workers and researchers in the startup to focus less on the work environment around them, and more on achieving the task at hand, giving them the potential to achieve something great for both themselves and their company.
Failure
The failure rate of startup companies is very high. A 2014 article in Fortune estimated that 90% of startups ultimately fail. In a sample of 101 unsuccessful startups, companies reported that experiencing one or more of five common factors were the reason for failure; lack of consumer interest in the product or service (42% of failures), funding or cash problems (29%), personnel or staffing problems (23%), competition from rival companies (19%) and problems with pricing of the product or service (18%).[5] In cases of funding problems it can leave employees without paychecks. Sometimes these companies are purchased by other companies if they are deemed to be viable, but oftentimes they leave employees with very little recourse to recoup lost income for worked time.[31] More than one-third of founders believe that running out of money led to failure. Second to that, founders attribute their failure to a lack of financing or investor interest. These common mistakes and missteps that happen early in the startup journey can result in failure, but there are precautions entrepreneurs can take to help mitigate risk. For example, startup studios offer a buffer against many of the obstacles that solo entrepreneurs face, such as funding and insufficient team structure, making them a good resource for startups in their earliest phases.[32]
Re-starters
Failed entrepreneurs, or restarters, who after some time restart in the same sector with more or less the same activities, have an increased chance of becoming a better entrepreneur.[33] However, some studies indicate that restarters are more heavily discouraged in Europe than in the US.[34]
Training
See also: Entrepreneurship education
Many institutions and universities provide training on startups. In the context of universities, some of the courses are entrepreneurship courses that also deal with the topic of startups, while other courses are specifically dedicated to startups. Startup courses are found both in traditional economic or business disciplines as well as the side of information technology disciplines. As startups are often focused on software, they are also occasionally taught while focusing on software development alongside the business aspects of a startup.[35]
“The best way of learning about anything is by doing.” – Richard Branson
Founders go through a lot to set up a startup. A startup requires patience and resilience, and training programs need to have both the business components and the psychological components.[36] Entrepreneurship education is effective in increasing the entrepreneurial attitudes and perceived behavioral control,[37] helping people and their businesses grow.[36] Most of startup training falls into the mode of experiential learning (Cooper et al., 2004; Pittaway and Cope, 2007), in which students are exposed to a large extent to a real-life entrepreneurship context as new venture teams (Wu et al., 2009).[13] An example of group-based experiential startup training is the Lean LaunchPad initiative that applies the principles of customer development (Blank and Dorf, 2012) and Lean Startup (Ries, 2011) to technology-based startup projects.
As startups are typically thought to operate under a notable lack of resources,[38] have little or no operating history,[39] and to consist of individuals with little practical experience,[40][41] it is possible to simulate startups in a classroom setting with reasonable accuracy. In fact, it is not uncommon for students to actually participate in real startups during and after their studies. Similarly, university courses teaching software startup themes often have students found mock-up startups during the courses and encourage them to make them into real startups should they wish to do so.[35] Such mock-up startups, however, may not be enough to accurately simulate real-world startup practice if the challenges typically faced by startups (e.g. lack of funding to keep operating) are not present in the course setting.[42]
To date, much of the entrepreneurship training is yet personalized to match the participants and the training.
Ecosystem
A startup ecosystem can contribute to local entrepreneurial culture.
The size and maturity of the startup ecosystem is where a startup is launched and where it grows to have an effect on the volume and success of the startups. The startup ecosystem consists of the individuals (entrepreneurs, venture capitalists, angel investors, mentors, advisors); institutions and organizations (top research universities and institutes, business schools and entrepreneurship programs and centres operated by universities and colleges, non-profit entrepreneurship support organizations, government entrepreneurship programs and services, Chambers of commerce) business incubators and business accelerators and top-performing entrepreneurial firms and startups. A region with all of these elements is considered to be a "strong" startup ecosystem.
One of the most famous startup ecosystems is Silicon Valley in California, where major computer and internet firms and top universities such as Stanford University create a stimulating startup environment. Boston (where Massachusetts Institute of Technology is located) and Berlin, home of WISTA (a top research area), also have numerous creative industries, leading entrepreneurs and startup firms. Basically, attempts are being made worldwide, for example in Israel with its Silicon Wadi, in France with the Inovallée or in Italy in Trieste with the AREA Science Park, to network basic research, universities and technology parks in order to create a startup-friendly ecosystem.
Although there are startups created in all types of businesses, and all over the world, some locations and business sectors are particularly associated with startup companies. The internet bubble of the late 1990s was associated with huge numbers of internet startup companies, some selling the technology to provide internet access, others using the internet to provide services. Most of this startup activity was located in the most well-known startup ecosystem - Silicon Valley, an area of northern California renowned for the high level of startup company activity:
The spark that set off the explosive boom of "Silicon startups" in Stanford Industrial Park was a personal dispute in 1957 between employees of Shockley Semiconductor and the company’s namesake and founder, Nobel laureate and co-inventor of the transistor William Shockley... (His employees) formed Fairchild Semiconductor immediately following their departure... After several years, Fairchild gained its footing, becoming a formidable presence in this sector. Its founders began leaving to start companies based on their own latest ideas and were followed on this path by their own former leading employees... The process gained momentum and what had once begun in a Stanford’s research park became a veritable startup avalanche... Thus, over the course of just 20 years, a mere eight of Shockley’s former employees gave forth 65 new enterprises, which then went on to do the same...[43]
Startup advocates are also trying to build a community of tech startups in New York City with organizations like NY Tech Meet Up[44] and Built in NYC.[45] In the early 2000s, the patent assets of failed startup companies were being purchased by people known as patent trolls, who assert those patents against companies that might be infringing the technology covered by the patents.[46]
Investing
Diagram of the typical financing cycle for a startup company
Startup investing is the action of making an investment in an early-stage company. Beyond founders' own contributions, some startups raise additional investment at some or several stages of their growth. Not all startups trying to raise investments are successful in their fundraising.
In the United States, the solicitation of funds became easier for startups as result of the JOBS Act.[47][48][49][50] Prior to the advent of equity crowdfunding, a form of online investing that has been legalized in several nations, startups did not advertise themselves to the general public as investment opportunities until and unless they first obtained approval from regulators for an initial public offering (IPO) that typically involved a listing of the startup's securities on a stock exchange. Today, there are many alternative forms of IPO commonly employed by startups and startup promoters that do not include an exchange listing, so they may avoid certain regulatory compliance obligations, including mandatory periodic disclosures of financial information and factual discussion of business conditions by management that investors and potential investors routinely receive from registered public companies.[51]
Investors are generally most attracted to those new companies distinguished by their strong co-founding team, a balanced "risk/reward" profile (in which high risk due to the untested, disruptive innovations is balanced out by high potential returns) and "scalability" (the likelihood that a startup can expand its operations by serving more markets or more customers).[citation needed] Attractive startups generally have lower "bootstrapping" (self-funding of startups by the founders) costs, higher risk, and higher potential return on investment. Successful startups are typically more scalable than an established business, in the sense that the startup has the potential to grow rapidly with a limited investment of capital, labor or land.[52] Timing has often been the single most important factor for biggest startup successes,[53] while at the same time it's identified to be one of the hardest things to master by many serial entrepreneurs and investors.[54]
Startups have several options for funding. Revenue-based financing lenders can help startup companies by providing non-dilutive growth capital in exchange for a percentage of monthly revenue.[55] Venture capital firms and angel investors may help startup companies begin operations, exchanging seed money for an equity stake in the firm. Venture capitalists and angel investors provide financing to a range of startups (a portfolio), with the expectation that a very small number of the startups will become viable and make money. In practice though, many startups are initially funded by the founders themselves using "bootstrapping", in which loans or monetary gifts from friends and family are combined with savings and credit card debt to finance the venture. Factoring is another option, though it is not unique to startups. Other funding opportunities include various forms of crowdfunding, for example equity crowdfunding,[56] in which the startup seeks funding from a large number of individuals, typically by pitching their idea on the Internet.
Startups can receive funding via more involved stakeholders, such as startup studios. Startup studios provide funding to support the business through a successful launch, but they also provide extensive operational support, such as HR, finance and accounting, marketing, and product development, to increase the probability of success and propel growth. [57]
Necessity of funding
While some (would-be) entrepreneurs believe that they can't start a company without funding from VC, Angel, etc. that is not the case.[58] In fact, many entrepreneurs have founded successful businesses for almost no capital, including the founders of MailChimp, Shopify, and ShutterStock.[59]
Valuations
If a company's value is based on its technology, it is often equally important for the business owners to obtain intellectual property protection for their idea. The newsmagazine The Economist estimated that up to 75% of the value of US public companies is now based on their intellectual property (up from 40% in 1980).[60] Often, 100% of a small startup company's value is based on its intellectual property. As such, it is important for technology-oriented startup companies to develop a sound strategy for protecting their intellectual capital as early as possible.[61] Startup companies, particularly those associated with new technology, sometimes produce huge returns to their creators and investors—a recent example of such is Google, whose creators became billionaires through their stock ownership and options.
Investing rounds
When investing in a startup, there are different types of stages in which the investor can participate. The first round is called seed round. The seed round generally is when the startup is still in the very early phase of execution when their product is still in the prototype phase. There is likely no performance data or positive financials as of yet. Therefore, investors rely on strength of the idea and the team in place. At this level, family friends and angel investors will be the ones participating. At this stage the level of risk and payoff are at their greatest. The next round is called Series A. At this point the company already has traction and may be making revenue. In Series A rounds venture capital firms will be participating alongside angels or super angel investors. The next rounds are Series B, C, and D. These three rounds are the ones leading towards the Initial Public Offering (IPO). Venture capital firms and private equity firms will be participating.[62] Series B: Companies are generating consistent revenue but must scale to meet growing demand. Series C & D: Companies with strong financial performance looking to expand to new markets, develop new products, make an acquisition, and/or preparing for IPO.
History of startup investing
After the Great Depression, which was blamed in part on a rise in speculative investments in unregulated small companies, startup investing was primarily a word of mouth activity reserved for the friends and family of a startup's co-founders, business angels, and Venture Capital funds. In the United States, this has been the case ever since the implementation of the Securities Act of 1933. Many nations implemented similar legislation to prohibit general solicitation and general advertising of unregistered securities, including shares offered by startup companies. In 2005, a new Accelerator investment model was introduced by Y Combinator that combined fixed terms investment model with fixed period intense bootcamp style training program, to streamline the seed/early-stage investment process with training to be more systematic.
Following Y Combinator, many accelerators with similar models have emerged around the world. The accelerator model has since become very common and widely spread and they are key organizations of any Startup ecosystem. Title II of the Jumpstart Our Business Startups Act (JOBS Act), first implemented on 23 September 2013, granted startups in and startup co-founders or promoters in US. the right to generally solicit and advertise publicly using any method of communication on the condition that only accredited investors are allowed to purchase the securities.[63][64][65] However the regulations affecting equity crowdfunding in different countries vary a lot with different levels and models of freedom and restrictions. In many countries there are no limitations restricting general public from investing to startups, while there can still be other types of restrictions in place, like limiting the amount that companies can seek from investors. Due to positive development and growth of crowdfunding,[66] many countries are actively updating their regulation in regards to crowdfunding.
Investing online
The first known investment-based crowdfunding platform for startups was launched in Feb. 2010 by Grow VC,[67] followed by the first US. based company ProFounder launching model for startups to raise investments directly on the site,[68] but ProFounder later decided to shut down its business due regulatory reasons preventing them from continuing,[69] having launched their model for US. markets prior to JOBS Act. With the positive progress of the JOBS Act for crowd investing in US., equity crowdfunding platforms like SeedInvest and CircleUp started to emerge in 2011 and platforms such as investiere, Companisto and Seedrs in Europe and OurCrowd in Israel. The idea of these platforms is to streamline the process and resolve the two main points that were taking place in the market. The first problem was for startups to be able to access capital and to decrease the amount of time that it takes to close a round of financing. The second problem was intended to increase the amount of deal flow for the investor and to also centralize the process.[70][71]
Internal startups
Internal startups are a form of corporate entrepreneurship.[72] Large or well-established companies often try to promote innovation by setting up "internal startups", new business divisions that operate at arm's length from the rest of the company. Examples include Bell Labs, a research unit within the Bell System and Target Corporation (which began as an internal startup of the Dayton's department store chain) and threedegrees, a product developed by an internal startup of Microsoft.[73] To accommodate startups internally, companies, such as Google has made strides to make purchased startups and their workers feel at home in their offices, even letting them bring their dogs to work.[74]
Unicorns
See also: List of unicorn startup companies
Some startups become big and they become unicorns, i.e. privately held startup companies valued at over US$1 billion. The term was coined in 2013 by venture capitalist Aileen Lee, choosing the mythical animal to represent the statistical rarity of such successful ventures. According to TechCrunch, there were 452 unicorns as of May 2019, and most of the unicorns are in the USA, followed by China. The unicorns are concentrated in a few countries. The unicorn leaders are the U.S. with 196 companies, China with 165, India with 107[75] and the U.K. with 16.[76] The largest unicorns included Ant Financial, ByteDance, DiDi, Uber, Xiaomi, and Airbnb. When the value of a company is over US$10 billion, the company will be called as a Decacorn. When the company is valued over US$100 billion, Hectocorn will be used.

Perhaps the greatest technological achievement of Peterhof is that all of the fountains operate without the use of pumps. Water is supplied from natural springs and collects in reservoirs in the Upper Gardens. The elevation difference creates the pressure that drives most of the fountains of the Lower Gardens, including the Grand Cascade. The Samson Fountain is supplied by a special aqueduct, over four km in length, drawing water and pressure from a high-elevation source.

I was in S.Maria in Trastevere, almost going home, sunset time. I was in the middle of the place, acting like a tourist pretending to have a look at the beauty of the church ... but ... I saw them and probably this time I would have gone away. And what happened? They whistled me! Damn!!! They called me and what do they say? Well, nice bike first of all, is it carbon or aluminium?
And ... by the way it's too late to take picture of the church, light is not that good!!! Too funny! "I don't wanna take pictures of the church guys, I wanna take pictures of you"!
So let's start: what's your name, 'cause I need to write down a few lines ... "My name is Black Man! In this way we solve every racial issue!". "I don't have any racial problem my friend, I would be glad if you told me your real name, if you want".
And after a while, Frank told me much more than his real name. French but from Ivory Coast originally, now he lives in Rome and was really really interested about the project. In the end we also had the time to joke about the 2006 World Cup of football, I love to make a fool of French people about football!
So thank you Frank "Black Man" for participating in my project and I hope to meet you again in Rome!

I've been having a few such frustrations lately, like a router that didn't believe it was configured so it would block some websites for no clear reason (I really just had to convince it that it was configured; the configuring was already done), and an updated desktop environment that breaks features that were common and generally worked something like three decades ago, like moving windows.

According to Kardashev, T₇ civilizations exist outside of spacetime and are capable of creating n-verses and destroying them just as easily. It's hard to imagine a story with such civilizations, since their perfection and indestructible nature would offer little conflict potential with lower civilizations. Recipe for paraversal tragedy.
It has been argued that KS may not be relevant or useful for classifying civilizations, assuming that behaviors would become predictable only if and when the correspondent civilizations are fully understood. Also, should a civilization be able to harness E of whatever arbitrarily large scale, such as a metagoogol¹ J, it does not mean that it has likewise developed a commensurate ability to use that E with efficiency. Posit a star system wherein a star-shrouding cloud of pebbles is hosting photosynthetic algæ or bacteria that almost completely surround a star, acquiring and having access to far more than the available E on ♁ either proportionately or in absolute terms: nonetheless, even if it were to completely absorb all E from said star, it would not be called a "technologically more advanced civilization" in virtue of its resource advantage alone.
FRB121102 is believed to be co-located in a DG @ 3E9 ly from ♁ with a low-luminosity AGN, or a previously unknown type of EG source, or a young NS energizing a SN remnant; it is presently in a heightened activity state and follow-on observations are encouraged, particularly @ higher RFs. In 2015-11, Paul Scholz @ McGill found 10 non-periodically repeated FRBs in archival data gathered in 2015-05&06 by ART with 3 times the max PD from a MW source and SP consistent with FRB121102. This finding is possibly ruling out self-destructive and cataclysmic SOEs, such as BHEs or NSCs, thus supporting an origin in a young pulsar, or in a magnetar, or from highly magnetized pulsars travelling through ABs, or from an intermittent RL overflow in a NS-WD binary complex. On 20161216, 6 new FRBs were reported in the same direction. This is the only known instance in which FRBs have been found twice in the same location in space. On 20170826, 15 FRBs from FRB121102 @ 5-8 GHz were detected via GBT data.

Technological change in the farming industry significantly affected the popularity of thatching. The availability of good quality thatching straw declined in England after the introduction of the combine harvester in the late 1930s and 1940s, and the release of short-stemmed wheat varieties. Increasing use of nitrogen fertiliser in the 1960s–70s also weakened straw and reduced its longevity. Since the 1980s, however, there has been a big increase in straw quality as specialist growers have returned to growing older, tall-stemmed, "heritage" varieties of wheat such as Squareheads Master (1880), N59 (1959), Rampton Rivet (1937), Victor (1910) and April Bearded (early 1800s)] in low input/organic conditions.

Some background:
In March 1941 Saab was given the task to design a better fighter than the Seversky Republic P-35s and Reggiane 2000s, at that time the only fighter aircraft Sweden was able or allowed to buy and the air force’s most modern fighters. Several other foreign designs, including the German Bf 109 or even the Japanese Mitsubishi Zero had also been considered.
Anyway, during the ongoing war the procurement of foreign equipment had no predictable future, and so a program for an indigenous fighter aircraft was launched the same year. This resulted in two different designs, which were both initially constructed around an imported German DB 603 engine – a deal which had become possible through the allowance of German transport flights to Norway over Swedish territory, a reason why no Allied equipment was sold to Sweden.
The resulting designs, the L-21 and L-23, differed considerably from each other. The Saab L-21 was a futuristic twin-boom pusher. This unconventional layout was a technological risk, with ejection seat and all, but it was expected to exploit the DB603 engine to the max, with a low-drag airframe (e .g. with a totally buried radiator installation inside of the inner wings) and a well-balanced center of gravity, which was expected to improve handling and turn radius. It was the favored design of Saab’s engineers.
As a fall-back option, though, the L-23 was added. It was a more conservative design with the same DB 603 engine, but with the engine in the classic nose position, a tunnel radiator under the rear fuselage, low tapered wings and a conventional tail. The overall outline resembled the P-51B/C Mustang. Most interestingly, the J 23 was to have a Bofors ejection seat, too, despite its conventional layout.
In December 1941 both designs were approved for prototypes, so that a direct comparison of both layouts could be made. The first of three J 21 prototypes flew on 30 July 1943, while the first three J 23 fighters followed on 10 August, just two weeks later.
Flight tests and evaluation continued until mid-1944 and, despite less weight and size, the J 23 turned out to be fast (Max. speed 626 km/h (388 mph) with the DB 603), but considerably less maneuverable than the J 21, which in itself was also not a perfect aircraft and frequently faced overheating problems.
Faced with two mediocre designs and an urgent need for a modern fighter, it was eventually decided to go ahead with the J 21 for serial production, but a pre-production batch of upgraded J 23 was also ordered for field tests and further development. In the meantime, Sweden had acquired rights to produce the DB 605 in license, and the new fighter was to be adapted to this more modern and powerful engine – it was hoped that the new engine would improve the J 23’s performance, and it was also fitted to the production J 21.
This re-engined variant was the J 23A, of which twelve aircraft were constructed at the main plant in Trollhättan and delivered from August 1945, too late to be involved in typical interception duties at the Swedish borders.
Deliveries of the favored J 21 started in December of the same year. The latter’s field performance turned out to be unsuited for the interceptor role, and the cooling problems persisted. Relegated mainly into the bomber and CAS role (the J 21 turned out to be a passable ground attack aircraft and a stable gun platform), the limitation of the J 21’s pusher design led to a revival of the front-engine J 23.
The resulting J 23B became the aircraft’s actual production variant, incorporating many improvements which had been developed and tested on the prototypes and the pre-production J 23As. These included aerodynamic modifications like a different airfoil on the outer wings and a lowered horizontal stabilizer, coupled with an extended rear fuselage for better directional stability and a slimmed-down radiator fairing for less drag. These machines were delivered from late 1946 on, and a total of forty-six J 23B airframes were produced until early 1948.
In service, the lighter J 23Bs proved to be a better interceptor than the J 21, with a higher top speed and rate of climb, but its handling was less responsive than the pusher aircraft with the same engine and armament.
Overall the J 23B was regarded as inferior to the very similar J 26 (the P-51D) in almost any respect, and the J 23B was never really popular with its flight or ground crews. Consequently, the J 23Bs active fighter career was short and the machines were only operated by the F 16 fighter wing and the F 20 Air Force Academy, both based at Uppsala Airfield, primarily used for advanced weapon and air combat training.
A new evaluation of the J 21 and the J 23 in 1947 led to the decision to retain the J 21 series but to consider the modification of the airframe to accommodate a jet engine. While production line J 21A series aircraft were first selected for conversion, the initial piston-engine version continued in production in five series "batches" that were completed in 1948–49.
Further J 23B production was not resumed, instead the J 26 and J 27 were procured. Anyway, the age of the piston-engine fighter came soon to a close and the Swedish Air Force entered the jet age. Consequently, the J 23B was already phased out, together with the J 21, after 1954.

The kit and its assembly:
The “Swedish Season” continues! The Saab 23 is another “phantom of the past”, a real world design that never left the drawing board. The J 23 actually started as an alternative to the J 21, but was discarded in late 1941 in favor of the more promising, yet bigger and heavier, pusher design. But that would not stop modelers from trying to build one, even though I have never seen a model of this aircraft? Having recently tried to build a Saab 27 fighter caught me in the right mood for another whiffy Swedish design, so I took a chance on the J 23, too.
At first glance you can mistake the J 23 for a P-51B with an engine from a late Bf 109, some sources describe it as “a Swedish Messerschmitt”. But that’s only superficial, much like the later Griffon-powered J 27 project which can be described as a “Super Spitfire”, but this does not do justice to the aircraft’s construction.
Both were independent developments, even though the P-51 (some early specimen were forced to land in Sweden and closely examined) certainly had a massive impact on both designs.
Anyway, the information basis surrounding the J 23 is worse than the J 27’s, and I only had rather vague profile drawings/sketches at hand for reference. A basis model was also hard to find: the rear section from a P-51B (in this case an Intech kit from Poland) was settled, since the Mustang’s cockpit shape, dorsal section and fin come really close to the J 23. But you cannot simply mate a P-51 with a Bf 109 nose, it would result in a rather wacky Mustang-thing because the proportions are not right.
Finding a good solution was not easy, and I was lucky to find a Hasegawa Ki-61 in the stash – it has a German engine (an earlier DB 601, though) and an overall layout similar to the P-51B. But the Ki-61 is considerably larger than a Bf 109, more in the P-51’s size class. Despite many detail modifications I decided to mate these unlikely aircraft for the J 23s basis – engraved panel lines on both kits made the combination less obvious, too.
The InTech P-51B gave its tail and the cockpit section (excluding the radiator tunnel and the wing roots), cut away from the rest of the Mustang fuselage with a Z-shaped cut. With a matching cut on the Ki-61’s fuselage, the engine and the whole wing/fuselage intersection were used. Styrene strips held the fuselage sections in place, on the outside the seams were later blended with nitrous compound putty. One benefit of this solution is that the OOB P-51 canopy could be used (even though the rear end fit necessitated some body work), and the resulting cockpit position was just as far forward as on the J 23, right above the wings. As a consequence the rear fuselage behind the cockpit appears to be rather long, but that is AFAIK correct, the J 23 had these slightly odd proportions!
For the J 23’s DB 605 engine a different, bigger spinner had to be mounted – scratched from a massive PZL 23 spinner and single blades (from the Hasegawa Ki-61), together with a metal axis and a styrene tube adapter inside of the nose. Some putty work was necessary to fair over the Ki-61 guns on the cowling, the typical DB 601 front bulge and blend the bigger, new spinner to the rest of the fuselage, but the result looks O.K.
The Ki-61’s original wings and landing gear could, thanks to the original fuselage section from the Hasegawa kit, be carried over and easily mounted, even though the wing tips were clipped for a square, Mustang-esque shape (the J 23’s look in all illustrations I’ve seen like upscaled Bf 109E wings).
The InTech P-51’s horizontal stabilizers were used, but for a J 23 they had to be placed in a different position: further back (so that wedges for the vertical rudder had to be cut out) and considerably lower, necessitating some (more) body work to hide the original attachment points. The new position adds to the impression of an extended fuselage section behind the cockpit, even though the P-51 donor fuselage section is only a little longer than the Ki-61’s. All tail surface outlines were slightly modified, too.
The J 23’s typical, shallow radiator tunnel had to be scratched, the semi-buried construction sits far behind the wings’ training edge. In an initial step, the removed Ki-61 radiator’s gap as well as the P-51 tail wheel well were faired over with styrene sheet and new intake/outlet ramps integrated into the lower rear fuselage. The tunnel itself is the narrow, aerodynamic fairing of a Boulton Paul Defiant’s machine guns behind the turret (raised when not in use), left over from a Pavla kit, opened at both ends.
As a consequence of the new and long radiator tunnel, the P-51 tail wheel well was moved about 5mm further back and the fuselage profile under the tail fin re-shaped.
One of the final steps was the cockpit interior, because I was not sure concerning the relative position of the P-51’s canopy (cut into three pieces for open display) and dashboard and the Ki-61’s cockpit floor panel and seat. But both turned out to match relatively well, and I added a tank and radio dummy behind the seat in order to prevent a clear view into the rear fuselage.
The landing gear was taken OOB from the Ki-61 – it looks similar to the real J 23 arrangement, so I stuck with it. The tail wheel comes from the InTech P-51, just the covers were scratched for the re-located well.
All gun barrels on spinner and wings are hollow steel needles, no ordnance was hung under the wings, even though the Ki-61 hardpoints were retained. After all, it’s a fighter aircraft.
Painting and markings:
Once more a classic, if not conservative, livery for a fictional aircraft – and in this case I chose the simple olivgrön/ljust blågrå camouflage of the late Fourties, coupled with contemporary color-coded letters identifying the individual aircraft and its squadron within the Flygflöttilj group.
The uniform upper surfaces were painted with RAF Dark Green (Humbrol 163). This tone has an olive drab touch and comes IMHO pretty close to the original Swedish color, the frequently recommended FS 34079 is IMHO too blue-ish. For the underside I used Humbrol 87 (Steel Gray), which is a blue-greenish gray. The authentic tone would be FS 36270, but on a model it appears much too dark, so that the lighter Steel Gray is a handy and individual alternative.
A light black ink was applied in order to emphasize the panel lines, some more depth was added through dry-painted panels with lighter shades of the basic colors (in this case, Humbrol 155 and 128).
The cockpit interior was painted in dark gray (Humbrol 32), while the landing gear and the wells became Aluminum (Humbrol 56).
As an aircraft of the air staff flight, this J 23 received a white spinner and a white code letter on the tail. These and other markings came from various sources and spare decal sheets. Some extra color was added with red warning markings on the wings above the flaps, plus some visual markings - all made with generic decal stripes. The cock nose art is a personal addition - taken from a Spanish Bf 109D, but AFAIK such personal markings were not uncommon on Swedish Air Force aircraft in the post WWII era.
An eye-catcher and some variety on the otherwise simple green/gray livery are white high-viz markings on the wing tips and a wide fuselage band. Such additional markings were frequently used in the post WWII-era during exercises, training or public displays. Styles varied considerably, though, between “color blocks” and wide single bands which I used (seen on a J 21) and even dense, thin zebra stripes on wings and fuselage. In this case, the white markings were painted onto wings and fuselage (Humbrol 34).
Since most panel lines on the fuselage were lost I painted some new ones with a soft pencil. Finally, after some gun soot and exhaust stains made with grinded graphite as well as some dry-brushed silver on the wings’ leading edges and around the cockpit were added, the kit received a coating with matt acrylic varnish.
Another scratch build of an obscure Swedish aircraft that never reached the hardware stage – and pretty successful, IMHO. This sleek J 23 model looks just as harmless and innocent, but involved massive construction work in almost every area as the kitbashed J 27 before. It’s actually the first model rendition of the J 23 I have seen so far – and another funny fact is that this “Swedish Messerschmitt” was built without any Bf 109 part at all!
Historic Science Building on the Texas Tech campus in Lubbock, Texas. The U-shaped Spanish Renaissance Revival style building was constructed in 1950-51 and links the Chemistry Building and the old Library building. The building now houses the Departments of Physics and Geosciences.
The Science Building was listed on the National Register of Historic Places in 1996 as a contributing resource to the Texas Technological College Historic District (NRHP District No. 96000523). Texas Tech University was established in 1923 as Texas Technological College.
In this age of grand delusion
You walked into my life out of my dreams
I don't need another change
Still you forced a way into my scheme of things
You say we're growing
Growing heart and soul
In this age of grand delusion
You walked into my life out of my dreams
Sweet name, you're born once again for me
Sweet name, you're born once again for me
Oh sweet name, I call you again
You're born once again for me
Just because I believe don't mean I don't think as well
Don't have to question everything in Heaven or Hell

The NSU Ro 80 was a technologically advanced large sedan-type automobile produced by the German firm of NSU from 1967 until 1977. Most notable was the powertrain; a 113 bhp (86 kW), 995 cc twin-rotor Wankel engine driving the front wheels through a semi-automatic transmission employing an innovative vacuum system. It was voted Car of the Year for 1968 by European motoring writers.
Unfortunately for NSU, the car developed an early reputation for unreliability, from which it would never escape. The Wankel engine in particular suffered from heavy wear on the rotor tip seals, among many other problems, and some early cars required a completely rebuilt engine before 30,000 miles (50,000 km), with problems visible as early as 15,000 miles (24,000 kilometres). The fact that the rotary engine design was inherently thirsty (typically 15-18 mpg) and a poor understanding of the Wankel engine by dealers and mechanics did not help this situation. By the 1970 model year, most of these problems were resolved, but a necessarily generous warranty policy and damage to the car's reputation had undermined NSU's financial situation irreparably. NSU was acquired by Audi (of the Volkswagen group) in 1969. Second hand Ro80s were virtually worthless in the 1970s due to the well-publicised engine problems, and a common "cure" for an ailing rotary engine was to simply swap it for a Ford V4 "Essex" engine (as found in Mk1 Transits) purely as it was one of the few engines compact enough to fit in the Ro80's engine bay. Thus in an ironic twist, one of the smoothest engines in the world was replaced by one of the roughest. The NSU's unpopularity caused by the above problems means that surviving examples are very rare, and are now considered highly-prized classic cars with values to match, particularly as thanks to Mazda's perseverance with rotary design, the tip seal problem has been all but eradicated.
Other technological features of the Ro 80 aside from the powertrain were the four wheel ATE Dunlop disc brakes, which for some time were generally only featured on expensive sports or luxury saloon cars. The front brakes were mounted inboard, reducing the unsprung weight. The suspension was independent on all four wheels, with MacPherson struts at the front and semi-trailing arm suspension at the rear, both of which are space-saving designs commonly used today. Power assisted ZF rack and pinion steering was used, again foreshadowing more recent designs.
The car featured an automatic clutch which was commonly described as a three-speed semi-automatic gearbox: there was no clutch pedal but instead, on top of the gearknob, an electric switch that operated a vacuum system which disengaged the clutch. The gear lever itself then could be moved through a standard 'h pattern' gate.
Interior trim combined cloth covered seats with pvc headlining and a carpeted floor.
The styling, by Claus Luthe who was head of design at NSU and later BMW, was considered very modern at the time and still holds up well; the Ro 80 has been part of many gallery exhibits of modern industrial design. The large glass area foreshadowed 1970s designs such as Citroën's. The shape was also slippery, with a drag coefficient of 0.355 (very good for the era, although average for modern cars). This allowed for a top speed of 112 mph (179.2 km/h). Indeed, comparisons have been drawn between the design of the Ro80 and the superbly aerodynamic 1984 Audi 100 - the shape is very, very similar.
Series production started in October 1967: the last examples came off the production line in April 1977. There were 37,204 vehicles produced during the ten year production run.

Der NSU Ro 80 war eine Limousine der gehobenen Klasse von NSU, später Audi NSU. Er erschien 1967 mit einer revolutionären aerodynamischen Karosserie, die ihrer Zeit weit voraus war. Ebenfalls ungewöhnlich war der Wankelmotor, der 115 PS leistete. Dieser Motor machte in der Frühzeit durch häufige Dichtleistendefekte auf sich aufmerksam, denen jedoch der Hersteller mit kulantem Motorenaustausch begegnete. Dennoch litt der Ruf des neuen Modells und des Wankelmotors darunter erheblich.
Die konsequente Umsetzung der Keilform im Entwurf von Claus Luthe war ein stilprägender Impuls für das Automobildesign der 1980er-Jahre. Insbesondere bei Audi sollte das Erscheinungsbild des Ro 80 maßgeblich für ganze Fahrzeuggenerationen werden. Das charakteristische hintere Dreiecksfenster ist bis heute typischer Bestandteil des Designs bei Audi.
Der Ro 80 wurde in nur 37.398 Exemplaren bis 1977 produziert und blieb, technisch gesehen, ohne Nachfolger. Das letzte produzierte Fahrzeug wurde 1977 dem Deutschen Museum übergeben. Weitere Fahrzeuge sind unter anderem in der Pinakothek der Moderne in München, im Depot des Deutschen Technikmuseums Berlin, im Deutschen Zweirad- und NSU-Museum und im Audi Forum in Neckarsulm, im museum mobile in Ingolstadt, im EFA-Museum für Deutsche Automobilgeschichte in Amerang sowie in der Autostadt in Wolfsburg ausgestellt. Das Schnittmodell des Ro 80, mit dem der Wagen auf der IAA vorgestellt wurde, wird im Museum Autovision als Teil der Dauerausstellung Wankelmotor gezeigt.
Der weltweit älteste noch erhaltene NSU Ro 80 gehört einem Architekten aus Frankfurt am Main, und trägt die Fahrgestell-Nr. 80 001 061, Fertigungsdatum Donnerstag, der 19. Oktober 1967, Farbe saguntoblau.
Das „Ro“ im Namen steht für Rotationskolben im Gegensatz zu „K“ wie beim VW K 70, das für Kolben bzw. Hubkolben stand.
Bei den ersten Serienmotoren kam es infolge eines Konstruktionsfehlers zu vermehrten Motorschäden. Hatten die Motoren in der Erprobung über 200 000 km gehalten, so verloren sie in Kundenhand oft schnell an Kompression. Schnell wurde eine falsche Materialpaarung als Ursache dafür erkannt. Eilig wurden Material sowie die Teilung der Dichtleisten geändert und somit war das Dichtleistenproblem vorerst gelöst. In Verbindung mit einem Ferrotic-Mittelteil und einer härteren Enesilschicht mit höherem Siliziumkarbidanteil ging man später auf die ursprüngliche Dichtleistenteilung zurück. Ab Anfang 1970 wurden die neuen Ferrotic-Dichtleisten in die Serie eingeführt.
Als ebenfalls problematisch erwies sich die Doppelzündung, zum einen von der Einstellung her und zum anderen wegen des hohen Abbrands der Zündkontakte, was dann durch zu viel Frühzündung zu Motorschäden führte. Dies wurde durch eine Einfachzündung in Verbindung mit einer Hochspannungskondensatorzündung (HKZ) auf Kosten des Spritverbrauchs behoben. Die kulante Austauschpraxis führte zeitweise dazu, dass über 35 % der angeblich defekten Motoren in Ordnung waren. Nachdem der Zündzeitpunkt sowie der Vergaser neu eingestellt wurden und der Motor einen Probelauf auf dem Prüfstand absolviert hatte, wurden diese Motoren wieder als Austauschmotoren ausgeliefert.
Ein nicht unerheblicher Anteil an Motorschäden ging auf das Konto des Drehmomentwandlers, den man gegen das Schieberuckeln (verursacht durch den Umfangseinlass) einbaute und der zum Teil für den Mehrverbrauch des Ro 80 mitverantwortlich war. Da der Wankelmotor erheblich höher drehte (wohl eher wegen erheblicher Überdrehzahl aufgrund fehlender Drehzahlbegrenzung), passierte es bei einer Reihe Drehmomentwandlern, dass sie sich radial ausdehnten. Dadurch zogen sie sich axial zusammen und nun kollidierte das Pumpen- mit dem Turbinenrad. Da der Wandler im Motorölkreislauf hing, gelangten dadurch Späne in den Motor, was dann umgehend zu Motorschäden führte. Auch erwies sich ein kleines Nadellager im Wandler als anfällig, dessen häufiger Ausfall ebenfalls zu Spänen im Motoröl führte und damit indirekt für einen defekten Motor sorgte. Dies wurde dann durch einen verstärkten Wandler behoben. Ab Herbst 1971 führte man dann in Verbindung mit der Bosch-Hochspannungskondensatorzündung und thermischer Abgasentgiftung einen akustischen Drehzahlwarner ein, der die elektrische Benzinpumpe bei Überdrehzahl abschaltete und dadurch eine Überdrehzahl des Motors wirksam vermied.
Anfänglich war alle 20 000 km ein Ölwechsel nötig, der später jedoch entfiel. So mancher Fahrer glaubte deshalb, man müsste kein Öl mehr nachfüllen, worauf einige Motoren ohne Öl liegen blieben. Dieser Art Motorschäden begegnete man mit einer geänderten zweiflutigen Ölpumpe. Der Einlass für den Wandlerkreislauf wurde höher angesetzt. Bevor nun der Motorölkreislauf kein Öl mehr bekam, saugte der Wandlerkreislauf Luft, woraufhin der Wandleröldruck absank und die Öldruckanzeige aufleuchtete. Ignorierte der Fahrer die Warnlampe, übertrug der Wandler keine Kraft mehr an das Getriebe und das Auto blieb stehen. Spätestens jetzt wusste der nachlässige Fahrer, dass er vergessen hatte, den Ölstand zu kontrollieren.
Ein weiteres Problem, das ebenfalls direkt zu Motorschäden führte, war eine Öldosierpumpe ohne Nullanschlag. Dies führte dazu, dass, wenn diese Pumpe falsch eingestellt wurde, im Leerlauf kein Öl für die Trochoidenschmierung geliefert wurde. Daraufhin wurde eine geänderte Öldosierpumpe eingesetzt, die nun nicht mehr auf Null gestellt werden konnte.
Problematisch war auch, dass man gleich mehrere bis dahin unerprobte Verfahren in Verbindung mit dem Wankelmotor einführte. So hieß es von dem Enesilverfahren scherzhaft, es funktioniere nur bei Südwind, was auf die Witterungsempfindlichkeit anspielte. Auch gab es anfänglich Probleme mit der Dosierung und Korngröße des eingebetteten Siliziumkarbids und der Dosierung des Saccharin (das als Einebner für Nickelschichten in der Galvanik angewendet wird). Zudem waren die Werkstätten zum Teil mit der Technik rund um den Motor überfordert. Teilweise aber entwickelten einige Kunden auch geradezu kriminelle Energien. Kurz vor dem Ablauf der Garantie provozierten sie absichtlich einen Motorschaden.
Als das Dichtleistenproblem gelöst schien, kam es wieder zu gehäuften Motorschäden. Nun war es aber kein Konstruktionsfehler, sondern ein Zulieferer, der sich nicht an die Fertigungsvorschriften hielt.
Bei den letzten Ausführungen der Motoren bestanden die Dichtleisten komplett aus Ferrotic, diese Aggregate erwiesen sich als äußerst robust. Zusätzlich kam der Lebensdauer die Einführung des bleifreien Benzins entgegen. Anders als ein Viertakthubkolbenmotor dessen Ventilsitze mit Blei geschmiert werden mussten konnte der Wankelmotor des Ro 80 problemlos mit bleifreiem Kraftstoff betrieben werden, da beim Wankelmotor für die Gaswechselsteuerung keine Ventile benötigt werden.

The NSU Ro 80 was a technologically advanced large sedan-type automobile produced by the West German firm of NSU from 1967 until 1977 (only 37,402 NSU Ro 80 were produced in 10 Years time). Most notable was the powertrain; a 113 bhp (84 kW; 115 PS), 995 cc twin-rotor Wankel engine driving the front wheels through a semi-automatic transmission employing an innovative vacuum system. It was voted Car of the Year for 1968 by European motoring writers.
The NSU Ro80 was an advance preview of the 1980s for discerning '60s executive car buyers. It redefined the levels of expectation for buyers in its market sector. It handled beautifully, was huge inside, looked amazing and rode as well as any luxury saloon.
For a while, the NSU Ro80 had the world at its feet. But the problems soon started – its rotary engine was refined but unreliable, and warranty costs had crippled NSU. By the time the company fixed it, the energy crisis hit, and all of a sudden its 15mpg thirst was an unwanted burden. Modern technology has completely conquered the rotor tip problem, and a Ro80 is a brilliant classic car to own with the correct support.
