Washington D.C.

Washington, D.C. is the capital city of the United States of America. "D.C." stands for the "District of Columbia", the federal district containing the city of Washington. The city is named for George Washington, military leader of the American Revolution and the first President of the United States. The District of Columbia and the city of Washington are coextensive and are governed by a single municipal government, so for most practical purposes they are considered to be the same entity. It is known locally as the District or simply D.C. Historically, it was called the Federal City. The District of Columbia, founded on July 16, 1790, is a federal district as specified by the United States Constitution with limited—and sometimes contentious—local rule. The District is ruled "in all cases whatsoever" by the U.S. Congress, though its residents have no voting representative in that body. The land forming the original District came from the states of Virginia and Maryland. However, the area south of the Potomac River (39 mi² or about 100 km²) was returned, or "retroceded", to Virginia in 1847 and now is incorporated into Arlington County and the City of Alexandria. The term "District of Columbia" is derived from an old poetic name for the United States, Columbia, which has fallen out of common use since the early 20th century. The centers of all three branches of the U.S. federal government are in Washington, D.C., as well as the headquarters of most federal agencies. Washington also serves as the headquarters for the World Bank, the International Monetary Fund, and the Organization of American States, among other international (and national) institutions. All of this has made Washington the frequent focal point of massive political demonstrations and protests, particularly on the National Mall. Washington is also the site of numerous national landmarks, museums, and sports teams, and is a popular destination for tourists. The population of the District of Columbia, as of 2003 U.S. Census Bureau estimates, is 563,384. The Greater Washington, D.C. metropolitan area includes the District of Columbia and parts of Maryland, Virginia, and West Virginia, with a population surpassing 4.7 million. If Washington, D.C. were considered a state, it would rank last in area behind Rhode Island, 50th in population ahead of Wyoming, and 36th in Gross State Product, ahead of 15 states. __TOC__

History

Wyoming map of Washington, D.C.]] A Southern site for the new country's capital was agreed upon at a dinner between Thomas Jefferson and Alexander Hamilton. The initial plan for the "Federal City" was a diamond, ten miles wide on each side, totaling 100 square miles (260 square kilometers). The actual site on the Potomac River was chosen by President Washington. Washington may have chosen the site for its natural scenery, believing the Potomac would become a great navigable waterway. The city was officially named "Washington" on September 9, 1791. Out of modesty, George Washington never referred to it as such, preferring to call it "the Federal City". Despite choosing the site and living nearby at Mount Vernon, he rarely visited. On August 24, 1814, British forces burned the capital during the most notable and destructive raid of the War of 1812. President James Madison and U.S. forces fled before the British forces, who burned public buildings including the Capitol, the Navy Yard, and the Treasury building. The Presidential Mansion was also gutted. James Madison Washington remained a small city of a few thousand permanent residents until the outbreak of the U.S. Civil War in 1861. The significant expansion of the federal government to administer the war and its legacies—such as veterans' pensions—led to notable growth in the city's population. In July 1864, Confederate forces under Jubal Anderson Early made a brief raid into Washington, culminating in the Battle of Fort Stevens. The Confederates were repulsed and Early eventually returned to the Shenandoah Valley. The site, now called [http://www.nps.gov/batt/ Battleground National Cemetery] is located near present day Walter Reed Army Medical Center in Northwest Washington. The battle was the only battle where a U.S. President, Lincoln, was present and under enemy fire while in office [http://www.nps.gov/rocr/ftcircle/stevens.htm 1]. In the early 1870s, Washington was given a territorial government, but Governor Alexander Shepherd's reputation for extravagance resulted in Congress abolishing his office in favor of direct rule. Congressional governance of the District would continue for a century. The Washington Monument opened in 1888. Plans were laid to further develop the monumental aspects of the city, with work contributed by such noted figures as Frederick Law Olmsted and Daniel Burnham. However, development of the Lincoln Memorial and other structures on the National Mall did not begin until the early 20th century. Lincoln Memorial The District's population peaked in 1950, when the census for that year recorded a record population of 802,178 people. At the time, the city was the ninth-largest in the country, ahead of Boston and behind Saint Louis. The population declined in the following decades, mirroring the suburban out-migration of many of the nation's older urban centers following World War II. The Twenty-third Amendment to the United States Constitution was ratified on March 29, 1961, allowing residents of Washington, D.C. to vote for president and have their votes count in the Electoral College. The first 4.6 miles (7.4 kilometers) of the Washington Metro subway system opened on March 27, 1976. Walter Washington became the first elected mayor of the District in 1974. Marion Barry became mayor in 1978, but he was arrested for drug use in an FBI sting on January 18, 1990 and would serve a six-month jail term. His successor, Sharon Pratt Kelly, became the first black woman to lead a city of that size and importance in the U.S. But Barry defeated her in the 1994 primary and was once again elected mayor for his fourth term, during which time the city nearly became insolvent and was forced to give up some home rule to a congressionally-appointed financial control board. On September 29, 2004, Major League Baseball officially relocated the Montreal Expos to Washington for the 2005 season, now named the Washington Nationals, despite opposition from Orioles owner Peter Angelos. A very public back-and-forth between the city council and MLB threatened to scuttle the agreement until December 21, when a plan for a new stadium in Southeast D.C. was finalized. The Nationals will play at R.F.K. Stadium until the new stadium is ready in 2008.

Geography and climate

Geography

2008, 2002. The axes bounding its quadrants radiate from the U.S. Capitol building.]] Washington, D.C. is located at (the coordinates of the Zero Milestone, on The Ellipse). According to the United States Census Bureau, the city has a total area of 177.0 km² (68.3 mi²). 159.0 km² (61.4 mi²) of it is land and 18.0 km² (6.9 mi²) of it is water. The total area is 10.16% water. Washington is surrounded by the states of Virginia (on its southwest side) and Maryland (on its southeast, northeast, and northwest sides); it interrupts those states' common border, which is the Potomac River's southern shore both upstream and downstream from the District. The Potomac River as it passes Washington is virtually entirely within the District of Columbia border. The physical geography of the District of Columbia is very similar to the physical geography of much of Maryland. The District has three major natural flowing bodies of water: the Potomac River, the Anacostia River, and Rock Creek. The Anacostia River and Rock Creek are tributaries of the Potomac River. There are also three man-made reservoirs: Dalecarlia Reservoir, which crosses over the northwest border of the District from Maryland; McMillan Reservoir near Howard University; and Georgetown Reservoir upstream of Georgetown. The highest point in the District of Columbia is 410 feet (125 m) above sea level at Tenleytown. The lowest point is sea level, which occurs along all of the Anacostia shore and all of the Potomac shore except the uppermost mile (the Little Falls - Chain Bridge area). The sea level Tidal Basin rose eleven feet during Hurricane Isabel on September 18, 2003. Geographical features of Washington, D.C. include Theodore Roosevelt Island, Columbia Island, the Three Sisters, and Hains Point.

Climate

Washington's weather is seasonal subtropical with some variations between summer and winter, although it is moderated by its proximity to the coast, making its climate more moderate than cities at a similar latitude further inland. Summer tends to be very hot and humid with daily high temperatures in July and August averaging in the high 80s° to low 90s°F (about 30°C). Spring and fall are mild with high temperatures in April and October averaging in the high 60s°F (about 20°C). Winter can bring cold temperatures and, on some occassions, significant snowfall. While hurricanes (or the remnants of them) occasionally track through the area, they have often weakened by the time they reach Washington. The average annual snowfall is 17 inches (430 mm) and the average high temperature in January is 43°F (6°C); the average low for January is 24°F (−4°C). The highest recorded temperature was 106°F (41°C) on July 20, 1930 and August 6, 1918 and the lowest recorded temperature was −15°F (−26°C) on February 11, 1899. 1899

According to the 2001 [http://www.gc.cuny.edu/faculty/research_studies/aris.pdf American Religious Identification Survey], nearly three out of four District residents self-identified as Christians. This breaks down to 72% Christian (27% Catholic, 19% Baptist, and 26% as some other form of Protestant), 13% stating no religion, and minor religions including 4% Buddhist, 2% Muslim, and 1% Jewish.

Housing

Due in part to the renewed expansion of the federal government, Washington has experienced a huge housing boom that has seen thousands of units constructed, along with thousands of people moving to the District. While the Census Bureau estimated in 2005 that the District's population will drop to 433,000 by 2030, city officials alleged systemic undercounting and released their own estimate that the District's population will rise to 712,000 by 2030.

Crime

During the violent crime wave of the early 1990s, Washington, D.C. was known as the murder capital of the United States. The number of homicides peaked in 1991 at 482, with violence declining drastically since then. Once plagued with violent crime, many D.C. neighborhoods, such as Columbia Heights, are becoming safe and vibrant areas as a result of gentrification. While not as intensely violent, crime hot spots have since displaced farther into the eastern sections of Washington, D.C. and across the border into Maryland. Although the eastern side of the city has developed a reputation for being unsafe, these crime hot spots are generally concentrated in very specific areas that are associated with drugs and gangs. Other areas east of the U.S. Capitol, as well as the city's wealthier Northwest neighborhoods, experience low levels of crime. Despite the declining trends, Washington D.C. crime rates (2004) remain among the highest of U.S. cities, behind only Camden, New Jersey, Detroit, Michigan, St. Louis, Missouri, and Gary, Indiana.

Landmarks and museums

Gary, Indiana Washington is home to numerous national landmarks and is one of the most popular tourist destinations in the United States. The National Mall is a large, open area in the center of the city featuring many monuments to American leaders, as well as connecting the White House and the United States Capitol buildings. Located prominently in the center of the Mall is the Washington Monument. Other notable points of interest near the Mall include the Jefferson Memorial (see right), Lincoln Memorial, Franklin Delano Roosevelt Memorial, National World War II Memorial, Korean War Veterans Memorial, Vietnam Veterans Memorial, and the Albert Einstein Memorial.

The Library of Congress and the National Archives house thousands of documents covering every period in American history. Some of the more notable documents in the National Archives include the Declaration of Independence and the United States Constitution. Other points of interest in the District include Arena Stage, Basilica of the National Shrine of the Immaculate Conception, Blair House, Folger Shakespeare Library, Ford's Theatre, Frederick Douglass National Historic Site, International Spy Museum, National Building Museum, Old Post Office Building, Theodore Roosevelt Island, United States Holocaust Memorial Museum, and the Washington National Cathedral.

Media

Newspaper

The Washington Post is the oldest and most-read daily newspaper in Washington, and has developed into one of the most reputable daily newspapers in the U.S., perhaps most notable for exposing the Watergate Scandal, among other achievements. The daily Washington Times and the free weekly Washington City Paper also have substantial readership in the District. On February 1, 2005 the free daily tabloid Washington Examiner debuted, having been formed from a chain of suburban newspapers known as the Journal Newspapers. The weekly Washington Blade focuses on gay issues, and the Washington Informer on African-American issues. Many neighborhoods in the District have their own small-circulation newspaper, usually published by the neighborhood association on a weekly basis. Some of these papers included the Dupont Current (Dupont Circle), Georgetown Current (Georgetown), In-Towner (Dupont Circle, Logan Circle, & Adams Morgan), Northwest Current (Upper Northwest), the Voice of the Hill, the Hill Rag (Capitol Hill), and East of the River (Anacostia).

Television

The metro area is well served by several local broadcast television stations, and is the eighth largest designated market area in the U.S., with 2,252,550 homes (2.04% of the U.S. population). Major television network affiliates include WUSA 9 (CBS), WJLA 7 (ABC), WRC 4, (NBC), WTTG 5 (Fox), WBDC 50 (WB), WDCA 20 (UPN), as well as WETA 26 and WHUT 32 (PBS) stations.

One channel is devoted to religious programming and the other channel provides a diversity of offerings. Several cable television networks have their headquarters in the Washington area including C-SPAN on Capitol Hill, Black Entertainment Television (BET) in Northeast Washington, and Discovery Communications in Silver Spring, Maryland. Major national broadcasters and cable outlets including NBC, ABC, CBS, Fox, and CNN also maintain a significant presence in Washington, as do those from around the world including the BBC, CBC, and Al Jazeera.

Radio

Al Jazeera There are also several major radio stations serving the metro area, with a wide variety of musical interests. Rock stations include WARW 94.7 FM (classic rock), WIHT 99.5 FM (top 40), WWDC, 101.1 FM (alternative rock), and WWZZ 104.1 FM (alternative rock).

XM Satellite Radio and National Public Radio are based in Washington. The Voice of America, the U.S. government's international broadcasting service, is also headquartered in Washington.

Performing arts

There are a number of venues for the performing arts in the city. Arena Stage, one of the first not-for-profit regional theaters in the nation, is rich with history and produces an eight-show season ranging from classics to world premieres, dedicated to the American canon of theater. The Kennedy Center for the Performing Arts hosts the National Symphony Orchestra, the Washington National Opera, the Washington Ballet, and a variety of other musical and stage performances. Notable local music clubs include Madam's Organ Blues Bar in Adams Morgan; the Eighteenth Street Lounge in the Dupont Circle district; and the Black Cat, the 9:30 Club, and the Bohemian Caverns jazz club, all in the U Street NW area. D.C. has its own native music genre, called go-go, a post-funk, percussion-driven flavor of R&B that blends live sets with relentless dance rhythms (that "go and go and go.") The most accomplished practitioner of go-go was D.C. bandleader Chuck Brown, who brought go-go to the brink of national recognition with his 1979 LP Bustin' Loose. Go-Go band and Washington natives Experience Unlimited hit the American pop charts in 1988 with their memorable dance tune "Da Butt". Washington was also an important center in the genesis of punk rock in the United States. Punk bands of note from Washington include Fugazi, Bad Brains, and Minor Threat. Native Washingtonians continue to support punk bands, long after the punk movement's popularity peaked. The region also has a storied indie rock history and was home to TeenBeat and Simple Machines, among other indie record labels. There have also been a number of television series that have featured the District. Most of these have been related to government (The West Wing) or security organizations (The District, Get Smart). Other programs had the nation's capital as a secondary focus, telling stories on their own that were not always tied to the infrastructure of the government either in the district or for the country. For instance, Murphy Brown focused on the lives of the reporters of the (fictional) Washington-based television newsmagazine, FYI. The soap opera Capitol allowed for stories about political intrigue alongside the traditional class struggle sagas. The sitcom 227 portrayed the life of the African-American majority as seen through the eyes of residents in a Washington apartment building.

Sports

Washington Metro area is home to several professional sports teams: the MLS D.C. United, the NHL Washington Capitals, the NBA Washington Wizards, the WNBA Washington Mystics, the MLB Washington Nationals, and the NFL Washington Redskins (now based at FedEx Field in Landover, Maryland). Other professional and semi-professional teams based in D.C. include the USAFL Baltimore Washington Eagles, the NWFA D.C. Divas, the Minor League Football D.C. Explosion, and the Washington Cricket League. It was also home to the WUSA Washington Freedom, and, during the 2000–2002 NLL seasons, the Washington Power was based in the city. There were two Major League Baseball teams named the Washington Senators in the early and mid-20th century, which left to become respectively the Minnesota Twins and the Texas Rangers. In the 19th century, the town was home to teams called the Washington Nationals, Washington Statesmen, and Washington Senators on and off from the 1870s to the turn of the century. Washington was also home to several Negro League teams, including the Homestead Grays, Washington Black Senators, Washington Elite Giants, Washington Pilots, and Washington Potomacs. The MCI Center in Chinatown, Washington, D.C., home to the Capitals, Mystics, Wizards, and the Georgetown Hoyas, is also a major venue for concerts, WWE professional wrestling, and other events. Washington also hosts the annual Legg Mason Tennis Classic tennis tournament that takes place at the Carter Barron Tennis Center on 16th Street.

Economy

Carter Barron Tennis Center Washington, D.C. is first and foremost a company town, with the primary company being, of course, the federal government. A significant portion of the metro area's population has some sort of connection to the federal government. Also, the presence of many major government agencies, including the Department of Defense, National Institutes of Health, or the Food and Drug Administration, has led to a significant amount of business development both in the District itself as well as in the suburbs of northern Virginia and Maryland. These businesses include federal contractors (defense and civilian), numerous nonprofit organizations, law firms and lobbying firms, catering and administrative services companies, and several other industries that are sustained by the enormous economic presence of the federal government. This arrangement has the effect of making the Washington economy virtually recession-proof relative to the rest of the country, because the federal government will still operate no matter the state of the general economy, and often grows during recessions. The metro area includes thirteen major Fortune 500 companies, including:
- Freddie Mac (McLean, Fairfax County)
- Fannie Mae
- electric utility Pepco Holdings Incorporated
- manufacturing company Danaher
- communications giant Nextel (Reston, Fairfax County)
- the credit card company Capital One (McLean, Fairfax County)
- AES Corporation (Arlington County)
- Gannett (McLean, Fairfax County), the publisher of USA Today
- SLM Corporation (Reston, Fairfax County)
- NVR Incorporated (McLean, Fairfax County)
- hotel services company Marriott International (Bethesda, Montgomery County)
- Choice Hotels (Silver Spring, Montgomery County)
- Coventry Healthcare Incorporated (Bethesda, Montgomery County) Defense contractors General Dynamics (Falls Church) and Lockheed Martin (Bethesda) are also in the metro area. In addition to Nextel, several other major network and communications companies are located in the area, including America Online (Dulles) and MCI Communications (Ashburn). Other media companies located in the DC metro area include the new XM Satellite Radio and Al Hurra (Springfield), a new cable new channel marketed towards Arabic countries. The Public Broadcasting Service is also based in suburban Alexandria, while Discovery Communications, the parent company of such cable networks as the Discovery Channel, is based in Silver Spring. The largest private employer in DC is the [http://wwww.bna.com Bureau of National Affairs], a publishing company based in the west end of the city since the early 1950s. The aerospace and commercial air travel industries also have a major presence in the area, in addition to the aforementioned General Dynamics, Lockheed Martin, and US Airways. Independence Air, based in Dulles, started service in 2004, and operates as a low-cost air carrier to many major airports in the United States. The regional airline Colgan Air, based in Manassas, also operates out of the DC area. Defense contractor Orbital Sciences Corporation is also based in Dulles and specializes in satellite launch and manufacture. Due to the proximity to the National Institutes of Health in Bethesda, the American genomics industry has recently sprouted in the Maryland suburbs of Washington. Prominent players are Celera Genomics, The Institute for Genomic Research (also known as "TIGR"), and Human Genome Sciences (all of which are in the city of Rockville). The gross state product of the District in 2004 was $75.264 billion, ranking it #36 when compared with the fifty states.

Infrastructure

Government

Local government

$ The city is run by an elected mayor (currently Anthony A. Williams) and a city council. The city council is composed of 13 members — a representative elected from each of the eight wards and five members, including the chairman, elected at large. The council conducts its work through standing committees and special committees established as needed. District schools are administered by a school board that has both elected and appointed members. There are also 37 elected Advisory Neighborhood Commissions that provide the most direct access for residents to their local government. The ANCs serve as local councils, and their suggestions are required to be given "great weight" by the DC Council. However, the U.S. Congress has the ultimate plenary power over the district. It has the right to review and overrule laws created locally, and has often done so. The Tenth Amendment to the United States Constitution does not apply to the District of Columbia. D.C. residents do pay all federal taxes, such as income tax, as well as local taxes. The mayor and council adopt a budget of local money with Congress reserving the right to make any changes. Much of the valuable property in the District is federally owned and hence exempt from local property taxes; at the same time, the city is burdened with the extraordinary expenses related to its role as the capital, such as police overtime and street cleaning for D.C.'s frequent parades and festivals. These factors are often used to explain why the city's budget is frequently overstretched. However, the federal government also appropriates funds for the city. For instance, according to Public Law 108-7, the federal government provided, among other funds, an estimated 25% of the District's operating budget in 2003. Historically, the city's local government has earned somewhat of a reputation for mismanagement and waste, particularly during the mayoralty of Marion Barry. A front page story in the July 21, 1997 Washington Post reported that Washington had some of the highest cost, lowest quality services in the region. Prosperity in the late 1990s and early 2000s has lessened public pressure on Mayor Williams, who still faces daunting urban renewal, public health, and public education challenges.

Representation in federal government

2000s The U.S. Constitution gives Congress direct jurisdiction for Washington, D.C. While Congress has delegated various amounts of this authority to local government, from time to time, Congress still intervenes in local affairs relating to schools, gun control policy, and other issues. Citizens of the District also lack voting representation in Congress, though they do have three electoral votes in the Presidential elections. Citizens of Washington are represented in the House of Representatives by a non-voting delegate (currently Eleanor Holmes Norton (D-DC At-Large)) who sits on committees and participates in debate but cannot vote. D.C. does not have representation in the Senate. Citizens of Washington, D.C. are thus unique in the world, as citizens of the capital city of every other country have the same representation rights as other citizens. Attempts to change this situation, including the proposed District of Columbia Voting Rights Amendment, have been unsuccessful. The history of D.C.'s relationship with the federal government, as well as the arguments for and against increased representation, are covered in the article District of Columbia voting rights.

Education

Public schools

The public school system in the city is operated by District of Columbia Public Schools (DCPS) and consists of 167 schools and learning centers, which breakdown into 101 elementary schools, 11 middle schools, 9 junior high schools, 20 senior high schools, 6 education centers, and 20 special schools. :See also: District of Columbia Public Schools

Private schools

Other schools in the city include the British School of Washington, Emerson Preparatory School, the Georgetown Day School, the Gonzaga Prepartory School, the Edmund Burke School, the Field School, the German School, the Maret School, the National Cathedral School, Our Lady of Victory, Reformed Theological Seminary, Sheridan School, the Sidwell Friends School, St. Albans School, St. Anselm's Abbey School, St. John's College High School, and the Washington Theological Union.

Colleges and universities

The city also is home to several universities, colleges, and other institutes of higher education, both public and private. The University of the District of Columbia is the city's public university; UDC is the nation's only urban land-grant university and is counted among the historically black colleges. The Department of Agriculture's Graduate School offers continuing-education and graduate-level classes. The Department of Defense maintains the National Defense University at Fort McNair. Among private institutions, Georgetown University is older than the District itself, dating to the late 18th century. It is also the nation's oldest Roman Catholic body of higher education. The two other Roman Catholic universities in the District are The Catholic University of America and Trinity University. The George Washington University, founded by an act of Congress in 1821, is the largest institution of higher education in the nation's capital with its main campus in Foggy Bottom and its Mount Vernon campus in the Foxhall neighborhood of Northwest Washington. GWU is also the second-largest landholder and employer in the District, second only to the Federal government. American University, chartered by act of Congress in 1893, is situated on a 72 acre campus in upper Northwest Washington and is well known for the Washington College of Law, the Kogod School of Business, the School of International Service, and the School of Communication. Also known for international affairs, The Johns Hopkins University Paul H. Nitze School of Advanced International Studies (SAIS), is dedicated to the graduate study of international relations and international economics and is located near Dupont Circle. Other notable private colleges in the District include Gallaudet University, the first school for the advanced education of the deaf and hard-of-hearing; Howard University, a historically black university dating to the 19th century; and Southeastern University. The Corcoran College of Art and Design has an arts program attatched to the Corcoran Museum of Art, adjacent to the White House Complex. Strayer University, a for-profit career school, has a campus in Washington, D.C.

Transportation

Aviation

Washington, D.C. is served by three major airports, two of them located in suburban Virginia and one located in Maryland. Ronald Reagan Washington National Airport is the closest — located in Arlington, Virginia, just across the Attempting to understand Time has long been a prime occupation for philosophers, scientists and artists. There are widely divergent views about its meaning, hence it is difficult to provide an uncontroversial and clear definition of time. The Oxford English Dictionary defines it as "the indefinite continued progress of existence and events in the past, present, and future, regarded as a whole". Another standard dictionary definition is "a non-spatial linear continuum wherein events occur in an apparently irreversible order." This article looks at some of the main philosophical and scientific issues relating to time. The measurement of time has also occupied scientists and technologists, and was a prime motivation in astronomy. Time is also a matter of significant social importance, having economic value ("time is money") as well as personal value due to an awareness of the limited time in each day and in our lives. Units of time have been agreed upon to quantify the duration of events and the intervals between them. Regularly recurring events and objects with apparently periodic motion have long served as standards for units of time - such as the apparent motion of the sun across the sky, the phases of the moon, the swing of a pendulum.

Philosophy of time

Main article: Philosophy of space and time; Ontology In ancient thought, Zeno's paradoxes challenged the conception of infinite divisibility, and eventually led to the development of calculus. Parmenides (of whom Zeno was a follower) believed that time, motion, and change were illusions, basing this on a rather interesting argument. More recently, McTaggart held a similar belief. Newton believed time and space form a container for events, which is as real as the objects it contains. In contrast, Leibniz believed that time and space are a conceptual apparatus describing the interrelations between events. Leibniz and others thought of time as a fundamental part of an abstract conceptual framework, together with space and number, within which we sequence events, quantify their duration, and compare the motions of objects. In this view, time does not refer to any kind of entity that "flows", that objects "move through", or that is a "container" for events. The bucket argument proved problematic for Leibniz, and his account fell into disfavour, at least amongst scientists, until the development of Mach's principle. Modern physics views the curvature of spacetime around an object as much a feature of that object as are its mass and volume. Immanuel Kant, in the Critique of Pure Reason, described time as an a priori notion that allows us (together with other a priori notions such as space) to comprehend sense experience. With Kant, neither space nor time are conceived as substances, but rather both are elements of a systematic framework necessarily structuring the experiences of any rational agent. Spatial measurements are used to quantify how far apart objects are, and temporal measurements are used to quantify how far apart events occur. Nietzsche, inspired by the concept of eternal return in his book Thus Spoke Zarathustra, argued that time possesses a circular characteristic. Postulating an infinite past, "all things" must have come to pass therein; the same for an infinite future. In Existentialism, time is considered fundamental to the question of being, in particular by the philosopher Martin Heidegger.

Contemporary theses in the philosophy of time

In contempoary philosophy there has been a very active debate over the nature of time, especially in light of the big changes in physics since the 1920s. Contributors include Ned Markosian, Ted Sider, Quentin Smith, and L. Nathan Oaklander. Two major theses have been developed, along with some hybrids. There is no real consensus among philosophers about which, if any, is correct. The two major theories can be summed up as follows: 1. A-theory of time: Presentism: Oaklander writes: "[A] version of the pure A-theory, known as "", purports to avoid… the problem of change... According to presentism, only the present exists. Thus, it is not the case that, say, O is green and [then] O is red [if, for example, O is a tomato]." (Oaklander, L. Nathan. In Smith, Quentin, and Oaklander, L. Nathan. 1995. Time, Change, and Freedom. New York: Routledge. 2004, 27.) 2. B-theory of time: Eternalism: the following passage from L. Nathan Oaklander sums this up
…[T]ime [involves] events strung out along a series united to one another by the relations of earlier than, later and simultaneity… The events in the temporal series are fixed in that they never change their position relative to each other… It has become customary to call the entire series of events spread out along the time-line from earlier to later, the “B-series.” When viewed solely in terms of the B-series, time is thought of as static or unchanging for there is nothing about temporal relations between events that changes... Time not only has a static aspect, it also has a transitory aspect. In addition to conceiving of time in terms of events standing in temporal relations, we also conceive of time and the events in time as moving or passing from the far future to the near future, from the hear future to the present, and then from present they recede into the more and more distant past… When events are ordered in terms of the notions of past, present, or future they form what is called an “A-series.” It should be noted, of course, that the A- and B-series are not really “two” different series of events, but the same series ordered in two different ways. (Oaklander 2004,Page 69)

Time in physics

never change Main article: Time in physics Time is currently one of the few fundamental quantities (quantities which cannot be defined via other quantities because there is nothing more fundamental known at present). Thus, similar to definition of other fundamental quantities (like space and mass), time is defined via measurement. Currently, the standard time interval (called conventional second, or simply second) is defined as 9 192 631 770 oscillations of a hyperfine transition in the 133Cs atom. Prior to Albert Einstein's relativistic physics, time and space had been treated as distinct dimensions; Einstein linked time and space into spacetime. Einstein showed that people traveling at different speeds will measure different times for events and different distances between objects, though these differences are minute unless one is traveling at a speed close to that of light. Many subatomic particles exist for only a fixed fraction of a second in a lab relatively at rest, but some that travel close to the speed of light can be measured to travel further and survive longer than expected. According to the special theory of relativity, in the high-speed particle's frame of reference, it exists for the same amount of time as usual, and the distance it travels in that time is what would be expected for that velocity. Relative to a frame of reference at rest, time seems to "slow down" for the particle. Relative to the high-speed particle, distances seems to shorten. Even in Newtonian terms time may be considered the fourth dimension of motion; but Einstein showed how both temporal and spatial dimensions can be altered (or "warped") by high-speed motion. Einstein (The Meaning Of Relativity - 1968): "Two events taking place at the points A and B of a system K are simultaneous if they appear at the same instant when observed from the middle point, M, of the interval AB. Time is then defined as the ensemble of the indications of similar clocks, at rest relatively to K, which register the same simultaneously."

Measurement

Present day standards

The standard unit for time is the SI second, from which larger units are defined like the minute, hour, and day. Because they do not use the decimal system, and because of the occasional need for a leap-second, the minute, hour, and day are "non-SI" units, but are officially accepted for use with the International System. There are no fixed ratios between seconds (or days) on the one hand and months and years on the other hand -- months and years having significant variations in length. Despite its great social importance, the week is not mentioned even as a "non-SI" unit. ([http://www1.bipm.org/utils/en/pdf/si-brochure.pdf See external pdf file: The International System of Units].) The measurement of time is so critical to the functioning of our modern societies that it is coordinated at an international level. The basis for scientific time is a continuous count of seconds based on atomic clocks around the world, known as International Atomic Time (TAI). This is the yardstick for other time scales including Coordinated Universal Time (UTC) which is the basis for civil time. The 60 base used for seconds, minutes and hours is all the remains of the ancient Phoenician counting base, using 60 as the equivalent of 10, or 100 in modern times. A 60 base is known as sexagesimal.

Chronology

Another form of time measurement consists of studying the past. Events in the past can be ordered in a sequence (creating a chronology), and be put into chronological groups (periodization). One of the most important systems of periodization is Geologic time, which is a system of periodizing the events that shaped the Earth and its life. Chronology, periodization, and interpretation of the past are together known as the study of history.

Psychology

Different people may judge identical lengths of time quite differently. Time can "fly"; that is, a long period of time can seem to go by very quickly. Likewise, time can seem to "drag," as in when one performs a boring task. The psychologist Jean Piaget called this form of time perception "lived time". Time appears to go fast when sleeping, or, to put it differently, time seems not to have passed while asleep. Time also appears to pass more quickly as one gets older. For example, a day for a child seems to last longer than a day for an adult. One possible reason for this is that with increasing age, each segment of time is an increasingly smaller percentage of the person's total experience. Altered states of consciousness are sometimes characterised by a different estimation of time. Some psychoactive substances--such as entheogens--may also dramatically alter a person's temporal judgement. In explaining his theory of relativity, Albert Einstein is often quoted as saying that although sitting next to a pretty girl for an hour feels like a minute, placing one's hand on a hot stove for a minute feels like an hour. This is intended to introduce the listener to the concept of the interval between two events being perceived differently by different observers.

Use of time

The use of time is an important issue in understanding human behaviour, education, and travel behaviour. The question concerns how time is allocated across a number of activities (such as time spent at home, at work, shopping, etc.). Time use changes with technology, as the television or the Internet created new opportunities to use time in different ways. However, some aspects of time use are relatively stable over long periods of time, such as the amount of time spent traveling to work, which despite major changes in transport, has been observed to be about 20-30 minutes one-way for a large number of cities over a long period of time. This has led to the disputed time budget hypothesis. Time management is the organization of tasks or events by first estimating how much time a task will take to be completed, when it must be completed, and then adjusting events that would interfere with its completion so that completion is reached in the appropriate amount of time. Calendars and day planners are common examples of time management tools. Arlie Russell Hochschild and Norbert Elias have written on the use of time from a sociological perspective.

Medieval Warm Period

The Medieval Warm Period (MWP) or Medieval Climate Optimum was an unusually warm period during the European Medieval period, lasting from about the 10th century to about the 14th century. It has been argued a better name would be the Medieval Climatic Anomaly. The MWP is often involved in controversial discussions of global warming and the greenhouse effect. greenhouse effect Initial research on the MWP and the following Little Ice Age (LIA) was largely done in Europe, where the phenomenon was most obvious and clearly documented. It was initially believed that the temperature changes were global. However, this view has been questioned; the 2001 IPCC report summarises this research, saying: "…current evidence does not support globally synchronous periods of anomalous cold or warmth over this timeframe, and the conventional terms of 'Little Ice Age' and 'Medieval Warm Period' appear to have limited utility in describing trends in hemispheric or global mean temperature changes in past centuries" [http://www.grida.no/climate/ipcc_tar/wg1/070.htm]. During this time wine grapes were grown in Europe and southern Britain [http://www.english-wine.com/history.html#domesday] [http://www.geog.ox.ac.uk/~knicoll/rsch/Geotimes%20-%20August%202004%20-%20Making%20Wine%20in%20a%20Changing%20Climate.htm] although less extensively than they are today [http://www.english-wine.com/vineyards.html] (however, factors other than climate strongly influence the commercial success of vineyards; and the time of greatest extent of medieval vineyards falls outside the MWP). The Vikings took advantage of ice-free seas to colonize Greenland and other outlying lands of the far north. The period was followed by the Little Ice Age, a period of cooling that lasted until the 19th century when the current period of global warming began. It has been noted that most paleoclimatologists developing regionally specific climate reconstructions of past centuries conventionally label their coldest interval as "LIA" and their warmest interval as the "MWP". Others follow the convention and when a significant climate event is found in the "LIA" or "MWP" time frames, associate their events to the period. Some "MWP" events are thus wet events or cold events, particularly in central Antarctica where climate patterns opposite to the North Atlantic area have been noticed.

Climate events

The Medieval Warm Period partially coincides in time with the peak in solar activity named the Medieval Maximum (AD 1100–1250). In Chesapeake Bay, Maryland, researchers found large temperature excursions during the Little Ice Age (~1400–1900 AD) and the Medieval Warm Period (~800–1300 AD) possibly related to changes in the strength of North Atlantic thermohaline circulation. [http://geology.er.usgs.gov/eespteam/Atlantic/GPCabs.htm] Sediments in Piermont Marsh of the lower Hudson Valley show a dry Medieval Warm period from 800–1300 AD. [http://eobglossary.gsfc.nasa.gov/Newsroom/NasaNews/2005/2005051918986.html] Prolonged droughts affected many parts of the western United States and especially eastern California and the western Great Basin. Alaska experienced three time intervals of comparable warmth: 1–300, 850–1200, and post-1800 AD. A radiocarbon-dated box core in the Sargasso Sea shows that sea surface temperature was approximately 1°C cooler than today approximately 400 years ago (the Little Ice Age) and 1700 years ago, and approximately 1°C warmer than today 1000 years ago (the Medieval Warm Period) [http://www.sciencemag.org/cgi/content/abstract/274/5292/1503?rbfvrToken=b3527f8140d1ddfd7f0fdac765ac49b01f52eacb]. However, all the reconstructions, as shown above say that it was not. The climate in equatorial east Africa has alternated between drier than today, and relatively wet. The drier climate took place during the Medieval Warm Period (~AD 1000–1270) [http://earthobservatory.nasa.gov/Newsroom/MediaAlerts/2004/2004100717709.html]. An ice core from the eastern Bransfield Basin, Antarctic Peninsula clearly identifies events of the Little Ice Age and Medieval Warm Period [http://www.ingentaconnect.com/content/ap/qr/2002/00000058/00000003/art02371]. The core clearly shows a distinctly cold period about 1000–1100 AD, nicely illustrating the fact that "MWP" is a moveable term, and that during the "warm" period there were, regionally, periods of both warmth and cold. Corals in the tropical Pacific ocean suggest that relatively cool, dry conditions may have persisted early in the millennium, consistent with a La Niña-like configuration of the ENSO patterns [http://www.pac.ne.jp/IUGG2003/EN/program.asp?session_id=MC12&program_id=022025-1].

Ottoman Empire

The Ottoman Empire (Ottoman Turkish: دولتِ عَليه عُثمانيه, Devlet-i Aliye-i Osmaniye, literally "Ottoman Sublime State") was an imperial power, centered around the borders of the Mediterranean Sea, that existed from 1299 to 1922. At the height of its power in the 16th century, it included Anatolia, the Middle East, parts of North Africa, much of south-eastern Europe to the Caucasus in the north. It comprised an area of about 19.9 million km², though much of this was under indirect control of the central government. The Empire was situated in the middle of East and West, and interacted throughout its six-century history with both the East and the West. It was established by a tribe of Oghuz Turks in western Anatolia, and was ruled by the Osmanlı dynasty, the descendants of those Turks. The Empire was founded by Osman I (in Arabic ʿUthmān, عُثمَان , hence the name Ottoman Empire). In 1453, after the Ottomans captured Constantinople (modern İstanbul), the last remnant of the Byzantine Empire, it became the Ottomans' third capital. In the 16th and 17th centuries, the Ottoman Empire was among the world's most powerful political entities, and the countries of Europe felt threatened by its steady advance through the Balkans and the southern part of the Polish-Lithuanian Commonwealth. At its highest point, the Empire contained many of the important places of classical antiquity, including Homer's Olympus and Dardenus, Zeus' Europa, Io's Bosporus, temple of Diana in Ephesus, sarcophagus of Alexander the Great, the Garden of Eden, Noah's Mount Ararat, Abraham's oasis and wells, Nile, Mount of the Sermon, the Hill of Golgotha. The dissolution of the Ottoman Empire was a consequence of World War I, when Allied forces including the Arabs eventually defeated Ottoman forces in the Middle East. At the end of the war the Ottoman government collapsed completely; and the empire was divided among the victorious powers. The following couple of years ended with declarations of new states. One of the new states was the Republic of Turkey. The members of the Ottoman dynasty were banned from the lands of Anatolia, where they once built one of the great empires of the world. In 1999, Turkey's parliament granted Turkish citizenship to the members of the Ottoman family, after 76 years.

History

Origins

The Ottoman Empire originated as a Uç Beyliği (cf. Marquisate, Marches) within the Seljukid State of Anatolia in the late 13th century; which, by then, was a puppet and vassal of Ilkhanate, itself. Traditionally, in 1299, Osman I declared independence for the Beylik.

Rise (1299–1453)

With the rise of the empire, the characteristics and nature of the state were defined, and the Ottomans definitively carved out their own preserve in history under the rule of Mehmed II. One of the first things the devout Islamic Turks did was name the city previously known as Constantinople, to its new name "Islambol" (meaning "Islam-Bound" or "lots of"). Bol in Turkish means "a lot of" so this name reflected the new state of the city and its people. The name of Islambol was used throughout the empire by the Ottomans right upto the beginning of the twentieth century. Even though Ottoman state existed before Osman I, he is regarded as the founder of the Empire, having given it its name and being the first bey to declare his independence. He extended the frontiers of the empire towards the Byzantine Empire, while other Turkish beyliks suffered from infighting. Under Osman I, the Ottoman capital was moved to Bursa. He published the first coin under his name, demonstrating the trust he built. For the coming centuries his time was recalled with the words "May he be as good as Osman". coin] Mehmed II was only 12 years old when he became sultan, and was reputed to have been an erudite warrior. His military prowess was demonstrated with his conquest of Constantinople (see the Fall of Constantinople). Mehmed also enjoyed the full support of the empire. He used this to reorganize the state structure and military.

Growth (1453–1683)

Fall of Constantinople–1683]] The growth of Ottoman power can be grouped into two main, characteristic periods. The first period is one of stable conquest and growth; from the conquest of Constantinople in 1453, to the death of Suleiman the Magnificent, in 1566. This was a period of amazing achievements for the Ottoman Empire. Following the acquisition of Constantinople, the Ottomans ended Serbian power at the Battle of Kosovo, which paved the way for expansion into Europe. Sultan Selim I (1512–1520) expanded the Empire's eastern frontiers, defeating Safavid Persia in the Battle of Chaldiran and establishing a navy in the Red Sea. His successor, Suleiman the Magnificent, would increase the Empire's size and power even further. After capturing Belgrade, Suleiman would conquer Hungary at the Battle of Mohacs, moving right up to Vienna. In the east, he would take Baghdad in 1535 from the Persians, giving the Ottomans control of the Middle East. Koca Mimar Sinan Agha was a skilled architect and engineer during this period. He took part in Selim's engineering corps. Later Sinan was promoted chief architect and was given the privilege of design, develop and implementation of the captured cities (according to the city plan). He was also appointed the command of the artillery. During a Persian campaign in 1535 he built ships for the army to cross Lake Van. For this he was given the title Haseki'i, Sergeant-at-Arms in the body guard of the Sultan, a rank equivalent to that of the Janissary Ağa. The Ottomans reached their "Golden Age" during Suleiman the Magnificent's reign. The end of these 230 years of growth marked with the end of extension into Europe. The Siege of Vienna was not part of an Ottoman extension into Germany. The Turks wanted to react to interventions of Austrian Habsburg interference into Hungary. But this turned some of the Ottoman allies against it. The Pope abandoned his secular interests, to agitate for a general Crusade against the Ottoman Empire.
