KCBS (AM)

KCBS (AM)

KCBS is an AM radio station in San Francisco, California that is a key West Coast radio station of the CBS Radio Network and Westwood One, broadcasting at 740 kHz. Its transmitter is located in Novato, California. The station has its roots in the experiments of San Jose tinkerer Charles Herrold as far back as 1909, making the broadcaster a leading contender for the title of oldest station in the United States and possibly the world. Herrold used a variety of different radio call signs in the early days, including FN, SJN, 6XF, 6XE, and KQW. In the very beginning, he just used a simple greeting like "San Jose calling." That greeting and the initial FN sign (which was an inverted abbreviation of "National Fone") reflected the fact that Herrold had been partially working on the idea of a radiotelephone. In 1949, the station was sold to CBS, and thus became KCBS-AM. Beginning in the 1960s, KCBS took on the format of all-news-and-information (a format that continues to this day). It is currently affiliated with CBS/Westwood One. KCBS is noted for broadcasts every weekday morning with former Oakland Raiders coach and sportscaster John Madden. The morning hosts speak with Madden and talk about upcoming football games, life on the road in his traveling bus, and various anecdotes in Madden's and the hosts' lives. KCBS does traffic on the 8's, has sports updates at :15 and :45 past the hour, and business news at :25 and :55 past the hour.

AM band

Mediumwave radio transmissions (sometimes called Medium frequency or MF) are those between the frequencies of 300 kHz and 3000 kHz. In most of the world, mediumwave serves as the most common band for broadcasting. The standard AM broadcast band is 525 kHz to 1715 kHz in North America, but remains only up to 1615 kHz elsewhere. Mediumwave signals have the property of following the curvature of the earth (the groundwave) at all times, and also reflecting off the ionosphere at night (skywave). This makes this frequency band ideal for both local and continent-wide service, depending on the time of day. For example, during the day a radio receiver in the state of Maryland is able to receive reliable but weak signals from high-power stations WFAN, 660 kHz, and WOR, 710 kHz, 400 km away in New York City, due to groundwave propagation. The effectiveness of groundwave signals largely depends on ground conductivity—higher conductivity results in better propagation. At night, the same receiver picks up signals as far away as Mexico City and Chicago reliably. Many stations are required to shut down or reduce power at night in order to make way for clear channel stations that can then be received over a wider range. In the Americas, mediumwave stations are separated by 10 kHz and have two sidebands of ±5 kHz. In the rest of the world, the separation is 9 kHz, with sidebands of ±4.5 kHz. Both provide adequate audio quality for voice, but are insufficient for high-fidelity broadcasting, which is common on the VHF FM bands. In the US the maximum transmitter power is restricted to 50 kilowatts, while in Europe there are medium wave stations with transmitter power up to 2.5 megawatts. Stereo transmission is possible and offered by some stations in the U.S., Australia, South Africa, and France. However, there are multiple standards for AM stereo with C-QUAM being the legal one in the United States, and receivers that actually implement the technologies are relatively rare but not uncommon. Failed systems include Kahn Powerside and others. In September 2002, the United States Federal Communications Commission approved the iBiquity in-band on-channel (IBOC) system of digital audio broadcasting, which is meant to improve the audio quality of signals. The Digital Radio Mondiale (DRM) IBOC system has been approved by the ITU for use outside the Americas.

Antennas

As aerials mostly mast radiators are used. Stations broadcasting with low power commonly use masts with heights of a quarter wavelength, while high power stations mostly use half wavelength. The usage of masts longer than 5/8 of radiated wavelength gives a bad radiation pattern. Usually mast antennas are insulated against ground and show a high voltage against ground during transmission, which complicates maintenance, installation of air safety warning lights or using the mast as a tower for UHF/VHF-radio, but there are several ways to use grounded masts or towers. wavelength If grounded masts or towers are required, than cage aerials or longwire aerials are used. Another possibility consists of feeding the mast or the tower by cables running from the tuning unit to the guys or crossbars in a certain height. Directional aerials consist of multiple masts, which need not to be from the same height. It is also possible to realize directional aerials for mediumwave with cage aerials where some parts of the cage are fed with a certain phase difference. Other type of aerials sometimes used for mediumwave are T- and L-aerials. The kind used depends on the need for grounded or insulated towers. In some cases dipole aerials are used, which are spun between two masts or towers. Such aerials radiate toward the sky. The mediumwave transmitter at Berlin-Britz for transmitting RIAS used a cross dipole mounted on five 30.5 metre high guyed masts to transmit the skywave up to the ionosphere at nighttime.

Non-broadcast use

For most of the 20th century, the radio frequency 500 kHz was reserved world wide as the Morse code international calling and distress frequency for ships on the high seas. The frequency 2182 kHz is still used for this purpose, but employing voice transmission. Other services that operate in medium wave include Navtex and the Amateur Radio 160-meter band. The obsolete LORAN-A system used medium wave.

San Francisco, California

: The City and County of San Francisco (2004 estimated population 744,230) is the fourth-largest city in the state of California, in the United States. A consolidated city-county, mainland San Francisco is located on the tip of the San Francisco Peninsula. Insular San Francisco includes several islands in the San Francisco Bay and the Golden Gate Strait, notably Alcatraz, Treasure Island, and the Farallon Islands 27 miles offshore in the Pacific Ocean and also most of the privately owned Red Rock Island near the Richmond-San Rafael Bridge. (See Islands of San Francisco Bay) The city is a focal point of the San Francisco Bay Area, and forms part of the greater San Jose-San Francisco-Oakland Combined Statistical Area (CSA), whose population is over 7 million. U.S. census data show that San Francisco has the highest population density of any major U.S. city aside from New York City. The first Europeans to settle in San Francisco were the Spanish, in 1776. With the advent of the California gold rush in 1848 the city entered a period of rapid growth. Devastated by the 1906 San Francisco earthquake, the city was quickly rebuilt. The phoenix on the city's flag represents San Francisco's "rebirth" from the ashes of the fire that resulted from the quake. Long enjoying a bohemian reputation the city became a counterculture magnet in the second half of the 20th century. It was a center of the dot-com boom and explosive growth of the internet at the end of the century. San Francisco has unique characteristics when compared to other major cities in the U.S., including its steep rolling hills, an eclectic mix of architecture including both Victorian style houses and modern skyscrapers, and unmatched physical beauty, surrounded by the Pacific Ocean and San Francisco Bay. San Francisco's famous hallmarks include its cable cars and the Golden Gate Bridge, which are recognized worldwide.

History

Golden Gate Bridge European visitors to the Bay Area were preceded 10,000 to 20,000 years earlier by Native Americans. When Europeans arrived, they found the area inhabited by the Yelamu tribe, belonging to a linguistic grouping later called the Ohlone (a Miwok Indian word meaning "western people") living in the coastal area between Point Sur and the San Francisco Bay. San Francisco's characteristic foggy weather and geography led early European explorers, including Juan Cabrillo and Sir Francis Drake (who would instead land a few miles north in Point Reyes), to pass by the Golden Gate and miss the San Francisco Bay. Eventually, a Spanish party, led by Don Gaspar de Portolà, discovered the bay in 1770, claiming it in the name of Spain. In 1776, Juan Bautista de Anza arrived and established the sites for the Presidio of San Francisco and Mission San Francisco de Asis (named for Saint Francis of Assisi and now popularly known as "Mission Dolores"). In 1792 British explorer George Vancouver set up a small settlement near the village of Yerba Buena (later downtown San Francisco) which became a small base for English, Russian, and other European fur traders, explorers, and settlers. Due to its distance from Mexico City and the decline of Spanish power, the area was isolated, remaining sparsely populated and undeveloped. It became part of an independent Mexico in 1821. Following the passing of the Secularization Act of 1833, effectively ending the Mission period, Mission San Francisco de Asis was abandoned. The local indigenous tribes of Ohlone and Miwok had became virtually extinct by this time due to disease and warfare with the European settlers. In addition to Spanish and European settlers, Russian colonists also visited the Bay area. From 1770, lasting through 1841, Russia colonized an area that ranged from Alaska south to Fort Ross in Sonoma County, California. The naming of San Francisco's Russian Hill neighborhood is attributed to the remains of Russian fur-traders and sailors found there. Serious development by non-Spanish speakers began in 1822, when William Richardson, an English whaler redeveloped a section of Yerba Buena in what is now Portsmouth Square in Chinatown. Yerba Buena remained a small town until the Mexican-American War broke out in 1846. The British Empire briefly entertained the idea of purchasing the bay from Mexico in 1841, claiming it would "Secure to Great Britain all the advantages of the finest port in the Pacific for her commercial speculations in time of peace, and in war for more easily securing her maritime ascendency". However little came of this, and San Francisco become a prize of United States continental imperialism rather than that of British thalassocratic power. A naval force under Commodore John D. Sloat claimed it in the name of the United States and renamed it "San Francisco" on January 30, 1847. Situated at the tip of a windswept peninsula without water or firewood, San Francisco lacked most of the basic facilities for a nineteenth century settlement. These natural disadvantages forced the town's residents to bring water, fuel and food to the site. The first of many environmental transformations was the city's reliance on filled marshlands for real estate. Much of the present downtown is built over the former Yerba Buena Cove, granted to the city by military governor Stephen Watts Kearny in 1847. Stephen Watts Kearny The California gold rush starting in 1848 led to a large boom in population, including considerable immigration. Between January 1848 and December 1849, the population of San Francisco increased from 1,000 to 25,000. This included many workers from China who came to work in the gold mines and later on the Transcontinental Railroad. The Chinatown district of the city became and is still one of the largest in the country; the city as a whole is roughly one-fifth Chinese, one of the largest concentrations outside of China. Many businesses founded to service the growing population exist today, notably Levi Strauss & Co. clothing, Ghirardelli chocolate, and Wells Fargo bank. Many famous railroad, banking, and mining tycoons or "robber barons" such as Charles Crocker, Mark Hopkins, Collis P. Huntington, and Leland Stanford settled in the city in its Nob Hill neighborhood. The sites of their mansions are now famous and expensive San Francisco hotels (Mark Hopkins Hotel and the Huntington Hotel). Huntington Hotel, 1856.]] As in many mining towns, the social climate in early San Francisco was chaotic. This was exacerbated by squabbling in the United States Senate, where the Compromise of 1850 was igniting a fierce fight over slavery. Committees of Vigilance were formed in 1851, and again in 1856, in response to crime and government corruption, but also had a strong element of anti-immigrant violence, and arguably created more lawlessness than they eliminated. This popular militia movement lynched 12 people, kidnapped hundreds of Irishmen and government militia members, and forced several elected officials to resign. The Committee of Vigilance relinquished power both times after it decided the city had been "cleaned up." This mob activity later focused on Chinese immigrants, creating many race riots. These riots culminated in the creation of the Chinese Exclusion Act in 1882 that aimed to reduce Chinese immigration to the United States by limiting immigration to males and reducing numbers of immigrants allowed in the city. The law was not repealed until 1943. Chinese Exclusion Act San Francisco County was one of the original counties of California, created in 1850 at the time of statehood. The parts of the county not in the city limits were split off to form San Mateo County in 1856. San Francisco became America's largest city west of the Mississippi River, until it lost that title to Los Angeles. It was also briefly the state capital in 1851, until San José received the title. (Sacramento is the current capital.) In autumn of 1855, a ship bearing refugees from an ongoing cholera epidemic in the far east (authorities disagree as to whether this was the
S.S. Sam or the S.S. Carolina) docked in San Francisco. As the city's rapid gold-rush area population growth had significantly outstripped the development of infrastructure, including sanitation, a serious cholera epidemic quickly broke out. The responsibility for caring for the indigent sick had previously rested on the state, but faced with the San Francisco cholera epidemic, the state legislature devolved this responsibility to the counties, setting the precedent for California's system of county hospitals for the poor still in effect today. The Sisters of Mercy were contracted to run San Francisco's first county hospital at the height of the cholera epidemic, and in 1857, the order opened its own charity hospital, Mercy Hospital of San Francisco, which is still in operation today at its original location on Stanyan Street. By the 1890s, San Francisco was suffering from Boss politics and corruption, and was ripe for political reform. Adolph Sutro ran for mayor in 1894 under the auspices of the Populist Party and won handily without campaigning. Unfortunately, except for the Sutro Baths, Mayor Sutro substantially failed in his efforts to improve the city. The next mayor, James D. Phelan elected in 1896, was more successful, pushing through a new city charter that allowed for the ability to raise funds through bond issues. He was able to get bonds passed to construct a new sewer system, seventeen new schools, two parks, a hospital, and a main library. After leaving office in 1901, Phelan became interested in remaking San Francisco into a grand and modern Paris of the West. When the San Francisco Art Association asked him to draft a plan for the beautification of the city, he hired famed architect Daniel Burnham. Burnham and Phelan's plan was ambitious, envisioning a 50-year effort to transform the city with wide diagonal boulevards creating open spaces and squares as they crossed the orthogonal grid of existing streets. Some parts of the plan were eventually implemented, including an Opera house to the north of City Hall, a subway under Market Street, and a waterfront boulevard (The Embarcadero) circling the city. In 1900, a ship from China brought with it rats infected with bubonic plague. Mistakenly believing that interred corpses contributed to the transmission of plague, and possibly also motivated by the opportunity for profitable land speculation, city leaders banned all burials within the city. Cemeteries moved to the undeveloped area just south of the city limit, now the town of Colma, California. A fifteen-block section of Chinatown was quarantined while city leaders squabbled over the proper course to take, but the outbreak was finally eradicated by 1905. However, the problem of existing cemeteries and the shortage of land in the city remained. In 1912 (with fights extending until 1942), all remaining cemeteries in the city were evicted to Colma, where the dead now outnumber the living by more than a thousand to one. The above-ground Columbarium of San Francisco was allowed to remain, as well as the historic cemetery at the Mission Dolores Church and The San Francisco National Cemetery in the Presidio of San Francisco. On April 18 1906, a devastating earthquake resulted from the rupture of over 270 miles of the San Andreas Fault, from San Juan Bautista to Eureka, centered immediately offshore of San Francisco. The quake is estimated by the USGS to have had a magnitude of 7.8 on the Richter scale. Water mains ruptured throughout San Francisco, and the fires that followed burned out of control for days, destroying approximately 80% of the city, including almost all of the downtown core. Many residents were trapped between the water on three sides and the approaching fire, and a mass evacuation (similar to that of the later Battle of Dunkirk) across the Bay saved thousands. Refugee camps were also set up in Golden Gate Park, Ocean Beach, and other undeveloped sections of the city. The official death toll at the time was 478, although it was officially revised in 2005 to 3,000+. The initial low death toll was concocted by civic, state, and federal officials who felt that reporting the actual numbers would hurt rebuilding and redevelopment efforts, as well as city and national morale. Ocean Beach In 1915, the city hosted the Panama-Pacific Exposition, officially to celebrate the opening of the Panama Canal, but also as a showcase of the vibrant completely rebuilt city less than a decade after the Earthquake. After the exposition ended, all of its grand buildings were demolished except for the Palace of Fine Arts which survives today in an abbreviated form. The San Francisco-Oakland Bay Bridge was opened in 1936 and the Golden Gate Bridge in 1937. During World War II, San Francisco was the major mainland supply point and port of embarkation for the war in the Pacific. The War Memorial Opera House in San Francisco has been the site of some significant post World War II history. In 1945, the conference that formed the United Nations was held there, with the UN Charter being signed on June 26. Additionally the Treaty of San Francisco which formally ended war with Japan and established peaceful relations, was drafted and signed here six years later in 1951. After World War II, many American military personnel who fell in love with the city during leaving to or returning from the Pacific, settled in the city prompting the creation of the Sunset District and Visitacion Valley. During this period, Caltrans commenced an aggressive freeway construction program in the Bay Area. However, Caltrans soon encountered strong resistance in San Francisco, for the city's high population density meant that virtually any right-of-way would displace a large number of people. Caltrans tried to minimize displacement (and its land acquisition costs) by building double-decker freeways, but the crude state of civil engineering at that time resulted in construction of some embarrassingly ugly freeways which ultimately turned out to be seismically unsafe. In 1959, the Board of Supervisors voted to halt construction of any more freeways in the city, an event known as the Freeway Revolt. Although some minor modifications have been allowed to the ends of existing freeways, the city's anti-freeway policy has remained in place ever since. In 1989, the Loma Prieta earthquake destroyed the Embarcadero Freeway and portions of the so-called Central Freeway. Over the course of several referenda, San Francisco's residents elected not to rebuild either structure. The neighborhoods once covered by these freeways have been rebuilt, and the restoration of the Embarcadero, San Francisco's historic bay waterfront, as a public space has been especially successful. In the 1950s San Francisco hired Harvard graduate Justin Herman to head the redevelopment agency for the city and county. Justin Herman began an aggressive campaign to renew blighted areas of the city. Enacting eminent domain whenever necessary, he set upon a plan to tear down huge areas of the city and replace them with modern construction. Critics accused Herman of racism for what was perceived as attempts to create segregation and displacement of African-Americans. Many African-Americans were forced to move from their homes near the Fillmore jazz district to newly constructed projects such as the near the naval base Hunter's Point or even to cities such as Oakland. He began leveling entire areas in San Francisco's Western Addition and Japantown neighborhoods. His planning led to the creation of Embarcadero Center, the Embarcadero Freeway, Japantown, the Geary Street superblocks, and Yerba Buena Gardens. San Francisco has often been a magnet for America's counterculture. During the 1950s, City Lights Bookstore in the North Beach neighborhood was an important publisher of Beat Generation literature. Some of the story of the evolving arts scene of the 1950s is told in the article San Francisco Renaissance. During the latter half of the following decade, the 1960s, San Francisco was the center of hippie and other alternative culture. In 1966 the Church Of Satan opened their headquarters, and in 1967 thousands of young people poured into the Haight-Ashbury district during what became known as the Summer of Love. At this time, the "San Francisco sound" emerged as an influential force in rock music, with such acts as the Jefferson Airplane and the Grateful Dead achieving international prominence, blurring the boundaries between folk, rock and jazz traditions and further developing the lyrical content of rock. During the 1980s and 1990s San Francisco became a major focal point in the North American--and international-- punk, thrash metal, and rave scenes. On the rave scene, the city was the first to host the Love Parade outside its birthplace of Berlin, Germany in 2004. It was also a hot spot during the 1980's for comedians like Ellen DeGeneres and Robin Williams who got major career boosts thanks to the presence of the city's popular comedy clubs. San Francisco's frontier spirit and wild and ribald character caused it to become known as a gay mecca beginning in the nineteenth century. This reputation was enforced greatly during World War II, when thousands of gay male soldiers spent time in the City, while en route to and from the Pacific theater. The late 1960s also brought in a new wave of lesbians and gays who were more radical and less mainstream and who had flocked to San Francisco not only for its gay-friendly reputation, but for its reputation as a radical, left-wing epicenter. These new residents were the prime movers of Gay Liberation and often lived communally, buying decrepit Victorians in the Haight and fixing them up. When drugs and violence began to become a serious problem in the Haight, many lesbians and gays simply moved "over the hill", to the Castro replacing Irish-Americans who had moved to the more affluent and culturally homogenous suburbs. The Castro became known as a Gay Mecca, and its gay population swelled as significant numbers of gay people moved to San Francisco in the 1970s and 1980s. The growth of the gay population caused tensions with some of the established ethnic groups in the western part of the city. On November 27, 1978 Dan White, a former member of the Board of Supervisors and former police officer, assassinated the city's mayor George Moscone and San Francisco's first openly gay elected official, Supervisor Harvey Milk (see "Twinkie Defense"). The murders and the subsequent trial were marked both by candlelight vigils and riots within the gay community. In the 1980s, the AIDS virus wreaked havoc on the gay male community there. Today, the gay population of the city is estimated to be approximately 15%, and gays remain an important force in the city's life. San Francisco has a higher percentage of gays and lesbians than any other major US city. During the administration of Mayor Dianne Feinstein (1978-1988), San Francisco saw a development boom referred to as "Manhattanization." Many large skyscrapers were built — primarily in the Financial District — but the boom also included high-rise condominiums in some residential neighborhoods. An opposition movement gained traction among those who felt the skyscrapers ruined views and destroyed San Francisco's unique character. Similar to the freeway revolt in the city decades earlier, a "skyscraper revolt" forced the city to embed height restrictions in the planning code. For many years, the limits slowed construction of new skyscrapers, but recent (2000-2005) housing pressures have led to master plan changes which will allow new construction of high-rise structures along The Embarcadero and in the South of Market district. South of Market During the 1980s, homeless people began appearing in large numbers in the city, the result of multiple factors including the closing of state institutions for the mentally ill, and social changes which increased the availability of addictive drugs. Combined with San Francisco's attractive environment and generous welfare policies the problem soon became endemic. Mayor Art Agnos (1988-92) was the first to attack the problem, and not the last; it is a top issue for San Franciscans even today. Agnos allowed the homeless to camp in the Civic Center park, which led to its title of "Camp Agnos." The failure of this policy led to his losing the election to Frank Jordan in 1991. Jordan launched the "MATRIX" program the next year, which aimed to displace the homeless through aggressive police action. And it did displace them - to the rest of the city. His successor, Willie Brown, was able to largely ignore the problem, riding on the strong economy into a second term. Present mayor Gavin Newsom's policy on the homeless is the controversial "Care Not Cash" program, which calls for ending the city's generous welfare policies towards the homeless and instead placing them in affordable housing and requiring them to attend city funded drug rehabilitation and job training programs. On October 17, 1989, an earthquake measuring 7.1 on the Richter magnitude scale struck on the San Andreas Fault near Loma Prieta Peak in the Santa Cruz mountains, approximately 70 miles south of San Francisco, a few minutes before game 3 of the 1989 World Series. The quake severely damaged many of the city's freeway's including the Embarcadero Freeway and the Central Freeway. The damage to these freeways was so extensive that they were eventually demolished. The quake also caused extensive damage in the Marina District and the South of Market. Known in most of the United States as the "World Series Quake," but in California and by seismologists as the Loma Prieta earthquake, it caused significant destruction and loss of life throughout the greater Bay Area. During the dot-com boom of the 1990s, large numbers of entrepreneurs and computer software professionals moved into the city, followed by marketing and sales professionals, and changed the social landscape as once poorer neighborhoods became gentrified. The rising rents forced many people and businesses to leave, and this caused considerable tension in the city's politics. The resulting backlash resulted in a progressive majority winning control of the Board of Supervisors in the 2000 election. By 2001, the boom was over, and many people left San Francisco. South of Market, where many dot-com companies were located, had been bustling and crowded with few vacancies, but by 2002 was a virtual wasteland of empty offices and for-rent signs. Much of the boom was blamed for the city's "fastest shrinking population", reducing the city's population by 30,000 in just a few years. While the boom has helped put an ease on the city's apartment rents, the city remains expensive nonetheless. In February 2004, San Francisco became the first city in the United States to grant marriage to gay couples when Mayor Gavin Newsom, elected the previous year, ordered the City Clerks office to issue same-sex marriage licenses. The California Supreme Court later invalidated these licenses, holding that Newsom had acted without proper authority. In 2005 San Francisco hosted the United Nations annual World Environment Day conference, the first in the United States, and banned outdoor smoking in all city-owned parks, plazas and public sports venues. Also as of December 2005, the crime rate has gone up, with more than 90 killngs throughout the year. San Francisco is also facing serious budget deficits, and, for such a small city, the homeless problem is still one of the worst in America.

Geography and climate

banned outdoor smoking Landsat 7]] San Francisco lies near the San Andreas Fault and Hayward Fault, two major sources of earthquake activity in California. The most serious earthquake, in 1906, is mentioned above. Earlier significant quakes rocked the city in 1851, 1858, 1865, and 1868. The Daly City Earthquake of 1957 caused some damage. The Loma Prieta earthquake of 1989, which also did significant damage to parts of the city, is also famous for having interrupted a World Series baseball game between the Bay Area's two Major League Baseball teams, the San Francisco Giants and the Oakland Athletics. The threat of another major earthquake like the 1906 one plays a major role in the city's infrastructure development. New buildings must be built to very high structural standards, while many dollars must be spent to retrofit the city's older buildings and bridges. Entire neighborhoods of the city such as the Marina and Hunters Point were created and sit on man made landfill (made up of mud, sand, and rubble from past earthquakes) and other reclamation projects over the San Francisco Bay when flatland became scarce. Such land is extremely unstable during earthquakes; the resultant liquefaction during earthquakes causes extensive damage to property built upon it, as was evidenced in the Marina district during the 1989 Loma Prieta Earthquake. The most impressive example of an "infill neighborhood" is Treasure Island. It was constructed from material dredged from the bay as well as material resulting from tunnelling through Yerba Buena Island in the construction of the Bay Bridge. It was a site for the 1939 San Francisco World's Fair, and it was originally envisioned that Treasure Island would serve as the site for San Francisco's municipal airport, but it became a Navy base at the start of World War II. In 1997 Treasure Island was returned to the city and it provides a unique vantage point to view the San Francisco skyline. San Francisco is famous for its hills. A "Hill" in San Francisco, is an elevation that is over 100 ft (30 Meters). There are a total of 42 hills within city limits. Some of these hills are neighborhoods such as Nob Hill, Pacific Heights, Russian Hill, and Telegraph Hill, while some of these hills are public parks and open space such as Twin Peaks, Mt. Sutro, Mount Davidson, and Buena Vista Park. Near the geographic center of the city and away from the downtown area are a series of less populated hills. Dominating this area is Mount Sutro, which is the site of Sutro Tower, a large red and white radio transmission tower, that is a well known landmark to city residents. Nearby are the equally well known Twin Peaks, which are a pair of hills resting at one of the city's highest points. About 1.2km (1 mile) south of Mount Sutro is San Francisco's highest mountain, Mount Davidson, which is over 282 meters (over 925 feet) high. On top of Mount Davidson is a 31.4 meter (103 foot) tall cross built in 1934. Twin Peaks Not to be missed are the beautiful homes and area of the city known as Pacific Heights as well as victorians in the Haight-Ashbury and the "painted ladies" of Alamo Square and the Castro. San Francisco is also famous for its Cable cars (narrow gauge, 1067 mm (3'6")), which were designed to carry residents up those steep hills. It is still possible to take a cable car ride up and down Nob and Russian Hills. Along with New Orleans' streetcars, San Francisco's cable cars are one of only two mobile United States National Monuments. Coit Tower, a notable landmark dedicated to San Francisco's firefighters, is located at the top of Telegraph Hill.

Climate

Surrounded on three sides by water, San Francisco's climate is strongly influenced by the cool currents of the Pacific Ocean. The weather is remarkably mild all year round, with a so-called Mediterranean climate characterized by cool, foggy summers and relatively warm winters; average daily high temperatures in the summer typically range from the upper 60's to mid 70's (15-22 degrees Celsius), while in the winter it virtually never reaches freezing. Rain in the summer is quite rare, but winters are very rainy. Snow is very rare. The Pacific Ocean off the west coast of the city is particularly cold year round. The combination of cold ocean water and the high heat of the California mainland creates the city's characteristic foggy weather that covers the western half of the city in fog all day during the summer and early fall, as well as the rest of the San Francisco metropolitan area as far as 35-50 miles inland in overcast and fog. Thus, the summer temperatures are significantly lower in San Francisco than in other parts of inland California. The fog is less pronounced during the months of September & October and during the late spring, which is generally the warmest, most summer-like months of the year. In January, morning lows average 46 °F (8 °C) and afternoon highs average 58 °F (14 °C). In August, lows average 56 °F (13 °C) and highs average 72 °F (22 °C). San Francisco receives an average of 22.28 inches (56.6 cm) of precipitation annually with July and August being almost completely free of precipitation. According to the United States Census Bureau, the city and county has a total area of 600.7 km² (231.9 mi²). 120.9 km² (46.7 mi²) of it is land and 479.7 km² (185.2 mi²) of it is water. The total area is 79.86% water. The city proper is often reputed to be roughly a seven mile square, and in fact is only slightly smaller. The geographical center of the city is on the east side of Grandview Avenue between Alvarado and Twenty-third Streets. mi²

Neighborhoods in San Francisco

mi² San Francisco has a Japantown and Chinatown; both are among the largest and oldest in the US. It also boasts a budding Vietnamese community in the Tenderloin neighborhood, Filipinos in Crocker-Amazon and South of Market, an Italian community in North Beach, a French Quarter, and Irish and Russian communities in the Richmond District. The predominantly Hispanic Mission District is the oldest neighborhood in the city, being the site of Mission Dolores, established in 1776. Russian Hill is a residential neighborhood most famous for Lombard Street "the crookedest street in the world". Haight-Ashbury gained prominence during the "Summer of Love" 1960s for its counter-culture and concentration of hippies. The Castro neighborhood has the world's highest concentration of homosexuals. In addition to the predominantly gay Castro, there are significant concentrations of gays in NoeValley, Diamond Heights, Bernal Heights, Potrero Hill, Haight-Ashbury, Hayes Valley, and SOMA. (See The Castro for more gay demographics.) The Castro") at Alamo Square]] Current demographic and land use expansion is concentrated in the east and south. The South of Market neighborhood was an epicenter of the dot-com boom of the late 1990s. A new neighborhood, Mission Bay, is being redeveloped from an industrial area at the far eastern end of South of Market. The cornerstones of this development are the SBC Park baseball stadium and an extension of the University of California, San Francisco medical school.

Parks

The best-known, as well as biggest, park is Golden Gate Park which is 174 acres larger than New York's Central Park. Another notable park is The Presidio at the south edge of the Golden Gate. The Presidio is part of the Golden Gate National Recreation Area, which includes Alcatraz, and many other large local parks. Buena Vista Park located in the Haight-Ashbury, is the city's oldest, established in 1867, nearby Alamo Square is famous for its views of the city and the famous Victorian houses known as the Painted Ladies. A large fresh-water lake, Lake Merced, is located in the south west corner of the city near San Francisco State University and Fort Funston. San Francisco also contains many public beaches such as Baker Beach and Ocean Beach.

Government and politics

As the official name implies, the City and County San Francisco is a metropolitan municipality, being simultaneously a charter city and charter county with a consolidated government. It is the only metropolitan municipality in California and the only California county with a mayor, who is also the county executive. San Francisco is the only California city with a board of supervisors, which is also the city council. San Francisco's unique status also makes it a municipal corporation and an administrative division of the state. It is in the latter capacity that San Francisco exercises jurisdiction over property that would otherwise be located outside of its corporation limit. San Francisco International Airport, for example, would be located within San Mateo County but for the fact it is owned and operated by the City and County of San Francisco. Because counties are administrative divisions of the state, it is legally impossible for two counties to occupy or exercise jurisdiction over the same piece of land. Thus, the airport, which is about 15 miles south of mainland San Francisco, is legally part of San Francisco because the municipality owns it. San Francisco exercises jurisdiction over the Hetch Hetchy Valley and watershed, in Yosemite National Park, pursuant to a perpetual leasehold granted by Act of Congress in 1913, the Raker Act. Under the current charter, the Government of San Francisco is constituted of two co-equal branches - the executive or administrative branch, which is headed by the mayor and includes other city-wide elected and appointed officials, and the civil service; and the legislative branch, which is constituted of the San Francisco Board of Supervisors, which exercises general oversight over all city and county functions. The mayor is elected every four years, in the odd-numbered year that precedes the U.S. presidential election. The current mayor, Gavin Newsom, was elected in December 2003 in a runoff competition against Matt Gonzalez (
see also List of Mayors of San Francisco, California). Gonzalez was president of the Board of Supervisors, representing District 5, and Newsom was a member of the board representing District 2. If the mayor dies or resigns, the President of the Board of Supervisors assumes the office until a special election can be held. The eleven members of the Board of Supervisors (as of January 2005) are listed in the table at right by district number[http://www.sfgov.org/site/bdsupvrs_index.asp?id=4385]. The current president of the Board is Aaron Peskin, who represents District 3. How the Board of Supervisors shall be elected has been a bone of contention in recent San Francisco history. Throughout the United States, almost all cities and counties with populations in excess of 20,000 divide the jurisdiction into electoral districts (in cities, often called "wards") to ensure proportionate representation of the whole community and to evenly distribute the community interaction workload evenly among the members of the governing body (city council, county board of supervisors, etc.) But California has always been disinclined to follow examples set by the rest of the country; and San Francisco, notwithstanding a population of 0.7 million, has been no exception. Prior to 1977 and again from 1980 through 2000, the San Francisco Board of Supervisors was elected at-large. All candidates appeared together on the ballot. The person who received the most votes was elected President of the Board of Supervisors, and the next ten were elected to seats on the board. The first district-based elections in 1977 resulted in a radical change to the composition of the Board, including the election of Harvey Milk, only the third openly gay or lesbian individual (and the first who was male) elected to public office in the United States. Following the assassinations of Supervisor Milk and Mayor George Moscone a year later, by Supervisor Dan White who had just resigned, district elections were deemed divisive and San Francisco returned to at-large elections until the current system was implemented in 2000. Under the current system, Supervisors are elected by district to four-year terms. The terms are staggered so that only half the board is elected every two years, thereby providing continuity. Supervisors representing odd-numbered districts (1, 3, 5, 7, 9, and 11) are elected every fourth year counted from 2000 (so, 2000, 2004, 2008, etc.). Supervisors representing even-numbered districts (2, 4, 6, 8, and 10) were elected to transitional two-year terms in 2000, thereafter to be elected every fourth year (2002, 2006, 2010, etc.). The President of the Board of Supervisors, under the new system, is elected by the members of the Board from among their number. This is done by secret ballot, typically at the first meeting of the new session commencing after the general election. The Mayor and members of the Board of Supervisors are subject to term limits under the San Francisco Charter. None may serve more than two consecutive terms. As part of the change to district elections, however, this provision applies to supervisors only as of the first full term of election following its implementation in 2000. Thus, Tom Ammiano, who was elected to the Board of Supervisors in 1994 and 1998 under the old system, then again in 2000 under the new system, was able to run yet again in 2004 (and won). A single vote transfer system of elections was approved by the electorate and implemented in time for the 2004 general election. This system replaced the old, expensive system of run-off elections. Under this new ranked-choice system, whenever there are more than two candidates for an office, voters rank their choices in order of preference. If a candidate does not achieve a majority of votes cast when the first choice votes are counted, the candidate with the least number of votes is eliminated and the second choice votes on those ballots are tabulated and "transferred" to the remaining candidates. The process continues, as necessary, until one candidate achieves a majority of votes cast and is then declared the winner. Eyed warily by some and optimistically by others - in both cases owing to the belief that single-transfer voting might favour so-called "progressive" and "minority party" candidates over so-called "conservative" and "mainstream party" candidates - the 2004 general election results showed that belief to be unfounded, as all incumbent Supervisors were returned to office. Vacancies on the Board of Supervisors are filled by mayoral appointment, subject to special election (except as the Charter permits an appointee to remain in office until the general election for the seat is held). A person appointed or elected to fill a vacancy of less than two years is not deemed to have served a full term for purposes of term limits, whereas a person who fills a vacancy with more than two years remaining in the term is deemed to serve a full term and will be able to run for a consecutive term only once. The Mayor's 2005-2006 proposed budget forecasts general fund expenditures of $2.44 billion. As the largest city on the west coast before World War I, San Francisco became and remains the legal hub for the western United States. The Ninth Circuit U.S. Court of Appeals and the Federal District Court for Northern California are headquartered in San Francisco. The Supreme Court of California is also headquartered in San Francisco, making The City the de facto judicial capital of the state. California is the only U.S. jurisdiction whose highest court and judicial seat is not in the official state or territorial capital. The California Supreme Court also maintains branch offices in Los Angeles and Sacramento. In addition, the city is the seat of the First Appellate District of the State Courts of Appeals and the San Francisco County Superior Court.

City flag

The flag depicts a rising Phoenix, symbolic of the City's recovery from the 1906 fire. Underneath the phoenix it has a motto written in Spanish: "Oro en Paz, Fierro en Guerra," which translates into: "Gold in Peace, Iron in War."

City seal

The seal, which was adopted in the 1850s, depicts two working men, on one side a miner and on the other a sailor with a sextant. Above is a rising phoenix and behind is the bay with sailing ships. The Phoenix symbolizes the city's emergence from the ashes of several devastating fires in the early 1850's.

Economy

Because of the California gold rush, San Francisco became and remains the banking and financial center of the U.S. West Coast. It is the home of the twelfth district of the U.S. Federal Reserve as well as major production facilities for the U.S. Mint. The Pacific Exchange is located in the financial district. Many major American and international banks and venture capital firms have all set up their regional headquarters in the city. Fortune 500 rankings indicated in parenthesis.

Education

The city is served by San Francisco Unified School District. Despite its limited geographical space, San Francisco is home to a multitude of Universities and Colleges. Public universities include:
- University of California, San Francisco, primarily a Medical School, located north of Forest Hill
- San Francisco State University located in the southwest corner of the city near Lake Merced
- University of California, Hastings College of the Law located downtown at its Civic Center
- City College of San Francisco, one of the largest community colleges in the country is located in the Ingleside, with several extension campuses. Private universities:
- The Jesuit-run University of San Francisco, one of the first universities established west of the Mississippi, located in the center of the city
- Golden Gate University, a business and law school located downtown
- NYSE:WON) is the largest radio network in the United States. It is based in the city of New York, and it is managed by Infinity Broadcasting, the radio arm of Viacom's CBS Corporation unit. The company is one of the largest producers and distributors of radio programming in the United States. It broadcasts entertainment, news, weather, sports, talk, and traffic programming to about 7,700 radio stations across the USA. The company is America's top provider of local traffic reports through its subsidiaries, Metro Networks, Shadow Broadcast Services and SmartRoute Systems. Commentators distributed by Westwood One include Don Imus, Bill O'Reilly, and Larry King. Westwood One distributes the radio news operations of CNN and NBC as well as its corporate cousin, the CBS Radio Network. The company broadcasts live concerts, college football and NHL hockey games, and also holds exclusive national radio rights for the National Football League, the Olympic Games, the NCAA Basketball Tournament (along with corporate sibling CBS TV), the Masters golf and Wimbledon tennis tournaments, and the Grammy Awards. Westwood One also owned the Mutual Broadcasting System. Purchased in 1985 and continued to operate Mutual as a separate network program service into the 1990s. However, by the early 1990's Mutual ended up simply being a brand name for programming provided by Westwood One. The top-of-the-hour newscasts were written and read by CBS Radio News reporters and anchors in Mutual's final years. Westwood One discontinued using the Mutual name in favor of CNN Radio in 1999 and the Mutual name passed permanently from use on the air. In the early- to mid-2000s, the company fell on hard times; lackluster service, especially in the MetroNetworks traffic services department, and overall neglect of equipment repair infuriated a number of the conglomerate's television and radio clients, many of whom affiliated themselves with Traffic.com, a relatively new traffic service company based in Wayne, Pennsylvania. Traffic.com's homebase figured prominently in the Westwood One company's downfall, as many of the company's former media clients in the city of Philadelphia ultimately cut ties with MetroNetworks to join its competitor, mostly due to the mismanagement of the Philadelphia branch by MetroNetworks regional operations managers Charlie Weirach and Richard Block. Within the span of two years, Weirach and Block managed to drive away three of the branch's television clients, including sister client KYW-TV, to the competition. Having provided exclusive traffic coverage for four of Philadelphia's six major television stations as recently as 2003, they currently retain one such client today. Many Philadelphia radio stations soon followed suit in 2004 and 2005.

Charles Herrold

Charles David 'Doc' Herrold, (November 16, 1875July 1, 1948) was an American radio broadcasting pioneer. Born in Fulton, Illinois, Herrold grew up in San Jose, California and attended Stanford University where he studied physics and astronomy. When his electrical manufacturing company in San Francisco was destroyed by the 1906 San Francisco earthquake he moved into teaching, and opened the Herrold College of Wireless and Engineering in San Jose in 1909 to educate wireless operators. Interested in radio to transmit voice signals, he began broadcasting music and entertainment on a regular basis between 1912 and 1917 to fellow radio enthusiasts, using the callsigns FN and SJN. However, in 1917, the US government ordered non-military radio transmissions to cease. After World War I, Herrold obtained the licence for KQW in 1921, but he was unable to maintain the financial requirements, and the station was sold and moved to San Francisco, later becoming KCBS. However, Herrold did not profit financially from his pioneering work, and later became a repair technician in the Oakland, California school district, and a janitor in a local shipyard. He died in a Hayward, California rest home, aged 73. Herrold, Charles Herrold, Charles Herrold, Charles Herrold, Charles Herrold, Charles

United States

:For alternative meanings, see the disambiguation page for US, USA, United States, or American. The United States of America is a federal democratic republic situated primarily in central North America. It comprises 50 states and one federal district, and has several territories. It is also referred to, with varying formality, as the United States, the U.S., the U.S.A., the States, or simply and most commonly, America. The official founding date of the United States is July 4, 1776, when the Second Continental Congress—representing thirteen British colonies—adopted the Declaration of Independence. However, the structure of the government was profoundly changed in 1788, when the states replaced the Articles of Confederation with the United States Constitution. The date on which each of the fifty states adopted the Constitution is typically regarded as the date that state "entered the Union" (became part of the United States). Since the mid-20th century, following World War II, the United States has emerged as a dominant global influence in economic, political, military, scientific, technological, and cultural affairs.

Geography and climate

The United States shares land borders with Canada (to the north) and Mexico (to the south), and territorial water boundaries with Canada, Russia, the Bahamas, and numerous smaller nations. It is otherwise bounded by the Pacific Ocean and the Bering Sea, in the west; the Arctic Ocean, in the northernmost areas; and the Atlantic Ocean, the Gulf of Mexico, and the Caribbean Sea, in the eastern and southeastern areas. Forty-eight of the states are in the single region between Canada and Mexico; this group is referred to, with varying precision and formality, as the continental or contiguous United States, sometimes abbreviated CONUS, and as the Lower 48. Alaska, which is not included in the term contiguous United States, is at the northwestern end of North America, separated from the Lower 48 by Canada. The archipelago of Hawaii is in the Pacific Ocean. The capital city, Washington, District of Columbia is a federal district located on land donated by the state of Maryland. (Virginia also donated land, but it was returned in 1847.) The United States also has overseas territories with varying levels of independence and organization. When inland water is included in the total area, only Russia and Canada are larger than the United States; if inland water is excluded, China ranks third and the U.S. ranks fourth. The United States' total area is 3,718,711 square miles (9,631,418 km²), of which land makes up 3,537,438 square miles (9,161,923 km²) and water makes up 181,273 square miles (469,495 km²). The United States' landscape is one of the most varied among those of the world's nations: among its many features are temperate forestland and rolling hills, on the east coast; mangrove, in Florida; the Great Plains, in the center of the country; the MississippiMissouri river system; the Great Lakes, four of the five of which are shared with Canada; the Rocky Mountains, west of the Great Plains; deserts and temperate coastal zones, west of the Rocky Mountains; and temperate rain forests, in the Pacific northwest. Alaska's tundra, and the volcanic, tropical islands of Hawaii add to the geographic diversity. Hawaii The climate varies along with the landscape, from tropical in Hawaii and southern Florida to tundra in Alaska and atop some of the highest mountains. Most of the North and East experience a temperate continental climate, with warm summers and cold winters. Most of the South experiences a subtropical humid climate with mild winters and long, hot, humid summers. Rainfall decreases markedly from the humid forests of the Eastern Great Plains to the semi-arid shortgrass prairies on the high plains abutting the Rocky Mountains. Arid deserts, including the Mojave, extend through the lowlands and valleys of the southwest, from westernmost Texas to California and northward throughout much of Nevada. Some parts of California have a Mediterranean climate. Rainforests line the windward mountains of the Pacific Northwest from Oregon to Alaska.

History

American history started with the migration of people from Asia across the Bering land bridge approximately 12,000 years ago following large animals that they hunted into the Americas. These Native Americans left evidence of their presence in petroglyphs, burial mounds, and other artifacts. It is estimated that 2-9 million people lived in the territory now occupied by the U.S. before European contact, and the subsequent introduction of foreign diseases such as small pox that greatly diminished the native populations. Some advanced societies were the Anasazi of the southwest, who inhabited Chaco Canyon, and the Woodland Indians, who built Cahokia, located near present-day St Louis, a city with a population of 40,000 at its peak in AD 1200. Vikings first visited North America around 1000, but did not settle permanently. Following the discovery voyages of Christopher Columbus around 1492, other Europeans began to explore and settle there. During the 1500s and 1600s, the Spanish settled parts of the present-day Southwest and Florida, founding St. Augustine, Florida in 1565 and Santa Fe (in what is now New Mexico) in 1607. The first successful English settlement was at Jamestown, Virginia, also in 1607. Within the next two decades, several Dutch settlements, including New Amsterdam (the predecessor to New York City), were established in what are now the states of New York and New Jersey. In 1637, Sweden established a colony at Fort Christina (in what is now Delaware), but lost the settlement to the Dutch in 1655. This was followed by extensive British settlement of the east coast. The British colonists remained relatively undisturbed by their home country until after the French and Indian War, when France ceded Canada and the Great Lakes region to Britain. Britain then imposed taxes on the 13 colonies, widely regarded by the colonists as unfair because they were denied representation in the British Parliament. Tensions between Britain and the colonists increased, and the thirteen colonies eventually rebelled against British rule. British Parliament, George Washington (1789-1797).]] In 1776, the 13 colonies split from Great Britain and formed the United States, the world's first constitutional and democratic federal republic, after their Declaration of Independence of that year, and the Revolutionary War (1775 to 1783). The original political structure was a confederation in 1777, ratified in 1781 as the Articles of Confederation. After long debate, this was supplanted by the Constitution in 1789, forming a more centralized federal government. Prior to all these was the Albany Congress in 1754, in which a union was first seriously proposed. From early colonial times, there was a shortage of labor, which encouraged unfree labor, particularly indentured servitude and slavery. In the mid-19th century, a major division occurred in the United States over the issue of states' rights and the expansion of slavery. The northern states had become opposed to slavery, while the southern states saw it as necessary for the continued success of southern agriculture and wanted it expanded to the territories. Several federal laws were passed in an attempt to settle the dispute, including the Missouri Compromise and the Compromise of 1850. The dispute reached a crisis in 1861, when seven southern states seceded1 from the Union and formed the Confederate States of America, leading to the Civil War. Soon after the war began, four more southern states seceded. During the war, Abraham Lincoln issued the Emancipation Proclamation, mandating the freedom of all slaves in states in rebellion, though full emancipation did not take place until after the end of the war in 1865, the dissolution of the Confederacy, and the Thirteenth Amendment took effect. The Civil War effectively ended the question of a state's right to secede, and is widely accepted as a major turning point after which the federal government became more powerful than state governments. Thirteenth Amendment). The title of the painting, from a 1726 poem by Bishop Berkeley, was a phrase often quoted in the era of Manifest Destiny, expressing a widely held belief that civilization had steadily moved westward throughout history. [http://americanart.si.edu/t2go/1lw/1931.6.1.html (more)] ]] During the 19th century, many new states were added to the original 13 as the nation expanded across the continent. Manifest Destiny was a philosophy that encouraged westward expansion in the United States. As the population of the Eastern states grew and as a steady increase of immigrants entered the country, settlers moved steadily westward across North America. In the process, the U.S. displaced most American Indian nations. This displacement of American Indians continues to be a matter of contention in the U.S. with many tribes attempting to assert their original claims to various lands. In some areas American Indian populations were reduced by foreign diseases contracted through contact with European settlers, and US settlers acquired those emptied lands. In other instances American Indians were removed from their traditional lands by force. Though some would say the U.S. was not a colonial power until the Spanish-American War when it acquired Puerto Rico, Guam and the Philippines, the dominion exercised over land in North America the United States claimed is essentially colonial. The Philippines became independent in 1946. During this period, the nation also became an industrial power. This continued into the 20th century, which has been termed "the American Century" because of the nation's overriding influence on the world. The US became a center for innovation and technological development; major technologies that America either developed or was greatly involved in improving include the telephone, television, computer, the Internet, nuclear weapons, nuclear power, aviation, and aeronautics. In addition to the Civil War, another major traumatic experience for the nation was the Great Depression (1929 to 1939). The nation has also taken part in several major foreign wars, including World War I and World War II (in both of which the US later joined the Allies). During the Cold War, the US was a major player in the Korean War and Vietnam War, and, along with the Soviet Union, was considered one of the world's two "superpowers". With the collapse of the Soviet Union, the US emerged as the world's leading economic and military power. Beginning in the 1990s, the United States became very involved in police actions and peacekeeping, including actions in Kosovo, Haiti, Somalia and Liberia, and the first Persian Gulf War driving Iraq out of Kuwait. After attacks on the World Trade Center and the Pentagon on September 11, 2001, the United States and other allied nations found themselves involved in what has come to be called the "War on Terrorism," which has primarily encompassed military actions in both Afghanistan and Iraq.

The United States is an example of a constitutional republic, with a government composed of and operating through a set of limited powers imposed by its design and enumerated in the United States Constitution. Specifically, the nation operates as a presidential democracy. There are three levels of government: federal, state, and local. Officials of each of these levels are either elected by eligible voters via secret ballot or appointed by other elected officials. Americans enjoy almost universal suffrage from the age of 18 regardless of race, sex, or wealth. There are some limits, however: felons are disenfranchised and in some states former felons are likewise. Furthermore, the national representation of territories and the federal district of Washington, DC in Congress is limited: residents of the District of Columbia are subject to federal laws and federal taxes but their only Congressional representative is a non-voting delegate.

Federal government

The federal government is the national government, comprising the Legislative Branch (led by Congress), the Executive Branch (led by the President), and the Judicial Branch (led by the Supreme Court). These three branches were designed to apply checks and balances on each other. The Constitution limits the powers of the federal government to defense, foreign affairs, the issuing and management of currency, the management of trade and relations between the states, and the protection of human rights. In addition to these explicitly stated powers, the federal government—with the assistance of the Supreme Court—has gradually extended these powers into such areas as welfare and education, on the basis of the "necessary and proper" clause of the Constitution.

The Congress

necessary and proper The Congress of the United States is the legislative branch of the federal government of the United States. It is bicameral, comprising the House of Representatives and the Senate. The House of Representatives consists of 435 members, each of whom represents a congressional district and serves for a two-year term. House seats are apportioned among the states by population; in contrast, each state has two Senators, regardless of population. There are a total of 100 senators, who serve six-year terms. The powers of Congress are limited to those enumerated in the Constitution; all other powers are reserved to the states and the people. The Constitution also includes the necessary-and-proper clause, which grants Congress the power to "make all laws which shall be necessary and proper for carrying into execution the foregoing powers."

The President

necessary-and-proper clause At the top level of the executive branch is the President of the United States. The President and Vice-President are elected as 'running mates' for four-year terms by the Electoral College, for which each state, as well as the District of Columbia, is allocated a number of seats based on its representation (or ostensible representation, in the case of D. C.) in both houses of Congress (see U.S. Electoral College). The relationship between the President and the Congress reflects that between the English monarchy and parliament at the time of the framing of the United States Constitution. Congress can legislate to constrain the President's executive power, even with respect to his or her command of the armed forces; however, this power is used only very rarely—a notable example was the constraint placed on President Richard Nixon's strategy of bombing Cambodia during the Vietnam War. The President cannot directly propose legislation, and must rely on supporters in Congress to promote his or her legislative agenda. The President's signature is required to turn congressional bills into law; in this respect, the President has the power—only occasionally used—to veto congressional legislation. Congress can override a presidential veto with a two-thirds majority vote in both houses. The ultimate power of Congress over the President is that of impeachment or removal of the elected President through a House vote, a Senate trial, and a Senate vote. The threat of using this power has had major political ramifications in the cases of Presidents Andrew Johnson, Richard Nixon, and Bill Clinton. The President makes around 2,000 executive appointments, including members of the Cabinet and ambassadors, which must be approved by the Senate; the President can also issue executive orders and pardons, and has other Constitutional duties, among them the requirement to give a State of the Union address to Congress once a year. Although the President's constitutional role may appear to be constrained, in practice, the office carries enormous prestige that typically eclipses the power of Congress: the Presidency has justifiably been referred to as 'the most powerful office in the world'. The Vice President is first in the line of succession, and is the President of the Senate ex officio, with the ability to cast a tie-breaking vote. The members of the President's Cabinet are responsible for administering the various departments of state, including the Department of Defense, the Justice Department, and the State Department. These departments and department heads have considerable regulatory and political power, and it is they who are responsible for executing federal laws and regulations. George W. Bush is the 43rd President, currently serving his second term.

The Courts

George W. Bush The highest court is the Supreme Court, which consists of nine justices. The court deals with federal and constitutional matters, and can declare legislation made at any level of the government as unconstitutional, nullifying the law and creating precedent for future law and decisions. Below the Supreme Court are the courts of appeals, and below them in turn are the district courts, which are the general trial courts for federal law. Separate from, but not entirely independent of, this federal court system are the individual court systems of each state, each dealing with its own laws and having its own judicial rules and procedures. A case may be appealed from a state court to a federal court only if there is a federal question; the supreme court of each state is the final authority on the interpretation of that state's laws and constitution.

State and local governments

Each state has its own written constitution and has different laws. There are sometimes great differences in law and procedure between the different states, concerning issues such as property, crime, health, and education. The highest elected official of each state is the Governor. Each state also has an elected legislature (bicameral in every state except Nebraska), whose members represent the different parts of the state. Of note is the New Hampshire legislature, which is the third-largest legislative body in the English-speaking world, and has one representative for every 3,000 people. Each state maintains its own judiciary, with the lowest level typically being county courts, and culminating in each state supreme court, though sometimes named differently. In some states, supreme and lower court justices are elected by the people; in others, they are appointed, as they are in the federal system. The institutions that are responsible for local government are typically town, city, or county boards, making laws that affect their particular area. These laws concern issues such as traffic, the sale of alcohol, and keeping animals. The highest elected official of a town or city is usually the mayor. In New England, towns operate directly democratically, and in some states, such as Rhode Island and Connecticut, counties have little or no power, existing only as geographic distinctions. In other areas, county governments have more power, such as to collect taxes and maintain law enforcement agencies.

Political divisions

With the Declaration of Independence, the thirteen colonies proclaimed themselves to be nation states modeled after the European states of the time. Although considered as sovereigns initially, under the Articles of Confederation of 1781 they entered into a "Perpetual Union" and created a fully sovereign federal state, delegating certain powers to the national Congress, including the right to engage in diplomatic relations and to levy war, while each retaining their individual sovereignty, freedom and independence. But the national government proved too ineffective, so the administrative structure of the government was vastly reorganized with the United States Constitution of 1789. Under this new union, the continued status of the individual states as sovereign nation states fell into dispute in 1861, as several states attempted to secede from the union; in response, then-President Abraham Lincoln claimed that such secession was illegal, and the result was the American Civil War. Since the Union victory in 1865, the independent status of the individual states has not been broached again by any state, and the status of each state within the union has been deemed by mainstream officials and academics to be settled as being subordinate to the union as a whole. In subsequent years, the number of states grew steadily due to western expansion, the purchase of lands by the national government from other nation states, and the subdivision of existing states, resulting in the current total of 50. The states are generally divided into smaller administrative regions, including counties, cities and townships. The United States–Canadian border is the longest undefended political boundary in the world. The U.S. is divided into three distinct sections:
- the "continental United States," also known as "the Lower 48" and more accurately termed the conterminous, coterminous or contiguous United States
- Alaska, which is physically connected only to Canada
- the archipelago of Hawaii, in the central Pacific Ocean. The United States also holds several other territories, districts, and possessions, notably the federal district of the District of Columbia, which is the nation's capital, and several overseas insular areas, the most significant of which are American Samoa, Guam, the Northern Mariana Islands, Puerto Rico, and the United States Virgin Islands. The Palmyra Atoll is the United States' only incorporated territory; it is
