Geographic coordinate system
–
A geographic coordinate system is a coordinate system used in geography that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are chosen such that one of the numbers represents a vertical position. A common choice of coordinates is latitude, longitude and elevation, to specify a location on a two-dimensional map requires a map projection. The invention of a coordinate system is generally credited to Eratosthenes of Cyrene. Ptolemy credited him with the adoption of longitude and latitude. Ptolemys 2nd-century Geography used the prime meridian but measured latitude from the equator instead. Mathematical cartography resumed in Europe following Maximus Planudes recovery of Ptolemys text a little before 1300, in 1884, the United States hosted the International Meridian Conference, attended by representatives from twenty-five nations. Twenty-two of them agreed to adopt the longitude of the Royal Observatory in Greenwich, the Dominican Republic voted against the motion, while France and Brazil abstained. France adopted Greenwich Mean Time in place of local determinations by the Paris Observatory in 1911, the latitude of a point on Earths surface is the angle between the equatorial plane and the straight line that passes through that point and through the center of the Earth. Lines joining points of the same latitude trace circles on the surface of Earth called parallels, as they are parallel to the equator, the north pole is 90° N, the south pole is 90° S. The 0° parallel of latitude is designated the equator, the plane of all geographic coordinate systems. The equator divides the globe into Northern and Southern Hemispheres, the longitude of a point on Earths surface is the angle east or west of a reference meridian to another meridian that passes through that point. All meridians are halves of great ellipses, which converge at the north and south poles, the prime meridian determines the proper Eastern and Western Hemispheres, although maps often divide these hemispheres further west in order to keep the Old World on a single side. The antipodal meridian of Greenwich is both 180°W and 180°E, the combination of these two components specifies the position of any location on the surface of Earth, without consideration of altitude or depth. The grid formed by lines of latitude and longitude is known as a graticule, the origin/zero point of this system is located in the Gulf of Guinea about 625 km south of Tema, Ghana. To completely specify a location of a feature on, in, or above Earth. Earth is not a sphere, but a shape approximating a biaxial ellipsoid. It is nearly spherical, but has an equatorial bulge making the radius at the equator about 0. 3% larger than the radius measured through the poles, the shorter axis approximately coincides with the axis of rotation

U.S. state
–
A U. S. state is a constituent political entity of the United States of America. There are 50 states, which are together in a union with each other. Each state holds administrative jurisdiction over a geographic territory. Due to the shared sovereignty between each state and the government, Americans are citizens of both the federal republic and of the state in which they reside. State citizenship and residency are flexible, and no government approval is required to move between states, except for persons covered by certain types of court orders. States range in population from just under 600,000 to over 39 million, four states use the term commonwealth rather than state in their full official names. States are divided into counties or county-equivalents, which may be assigned some local authority but are not sovereign. County or county-equivalent structure varies widely by state, State governments are allocated power by the people through their individual constitutions. All are grounded in principles, and each provides for a government. States possess a number of powers and rights under the United States Constitution, Constitution has been amended, and the interpretation and application of its provisions have changed. The general tendency has been toward centralization and incorporation, with the government playing a much larger role than it once did. There is a debate over states rights, which concerns the extent and nature of the states powers and sovereignty in relation to the federal government. States and their residents are represented in the federal Congress, a legislature consisting of the Senate. Each state is represented in the Senate by two senators, and is guaranteed at least one Representative in the House, members of the House are elected from single-member districts. Representatives are distributed among the states in proportion to the most recent constitutionally mandated decennial census, the Constitution grants to Congress the authority to admit new states into the Union. Since the establishment of the United States in 1776, the number of states has expanded from the original 13 to 50, alaska and Hawaii are the most recent states admitted, both in 1959. The Constitution is silent on the question of states have the power to secede from the Union. Shortly after the Civil War, the U. S. Supreme Court, in Texas v. White, as a result, while the governments of the various states share many similar features, they often vary greatly with regard to form and substance

Tennessee
–
Tennessee is a state located in the southeastern region of the United States. Tennessee is the 36th largest and the 17th most populous of the 50 United States, Tennessee is bordered by Kentucky and Virginia to the north, North Carolina to the east, Georgia, Alabama, and Mississippi to the south, and Arkansas and Missouri to the west. The Appalachian Mountains dominate the eastern part of the state, Tennessees capital and second largest city is Nashville, which has a population of 654,610. Memphis is the states largest city, with a population of 655,770, the state of Tennessee is rooted in the Watauga Association, a 1772 frontier pact generally regarded as the first constitutional government west of the Appalachians. What is now Tennessee was initially part of North Carolina, Tennessee was admitted to the Union as the 16th state on June 1,1796. Tennessee was the last state to leave the Union and join the Confederacy at the outbreak of the American Civil War in 1861, occupied by Union forces from 1862, it was the first state to be readmitted to the Union at the end of the war. Tennessee furnished more soldiers for the Confederate Army than any other state besides Virginia and this sharply reduced competition in politics in the state until after passage of civil rights legislation in the mid-20th century. This city was established to house the Manhattan Projects uranium enrichment facilities, helping to build the worlds first atomic bomb, Tennessees major industries include agriculture, manufacturing, and tourism. Poultry, soybeans, and cattle are the primary agricultural products, and major manufacturing exports include chemicals, transportation equipment. In the early 18th century, British traders encountered a Cherokee town named Tanasi in present-day Monroe County, the town was located on a river of the same name, and appears on maps as early as 1725. The meaning and origin of the word are uncertain, some accounts suggest it is a Cherokee modification of an earlier Yuchi word. It has been said to mean meeting place, winding river, according to ethnographer James Mooney, the name can not be analyzed and its meaning is lost. The modern spelling, Tennessee, is attributed to James Glen, the governor of South Carolina, the spelling was popularized by the publication of Henry Timberlakes Draught of the Cherokee Country in 1765. In 1788, North Carolina created Tennessee County, the county to be established in what is now Middle Tennessee. When a constitutional convention met in 1796 to organize a new out of the Southwest Territory. Other sources differ on the origin of the nickname, according to the Columbia Encyclopedia. Tennessee ties Missouri as the state bordering the most other states, the state is trisected by the Tennessee River. The highest point in the state is Clingmans Dome at 6,643 feet, Clingmans Dome, which lies on Tennessees eastern border, is the highest point on the Appalachian Trail, and is the third highest peak in the United States east of the Mississippi River

Franklin County, Tennessee
–
Franklin County is a county located in the U. S. state of Tennessee. As of the 2010 census, the population was 41,052, Franklin County is part of the Tullahoma-Manchester, TN Micropolitan Statistical Area. Euro-American settlement began around 1800, and the county was organized in 1807. During the next decades, the size of the county was reduced several times by reorganizations which created the neighboring counties of Coffee County, Moore County. One of the most notable early settlers was frontiersman Davy Crockett, the University of the South, founded by the Episcopal Church, was organized just before the Civil War. It began full operations shortly after hostilities ceased and it encompasses a full university and theological seminary. The University of Tennessee Space Institute is also located in the county, the area became strongly secessionist before the war. Franklin County formally threatened to secede from Tennessee and join Alabama if Tennessee did not leave the union and this contrasted sharply with the situation in nearby Winston County, Alabama, which was pro-Union and discussed seceding from Alabama. The two illustrate the often divided and confused state of loyalties in the central South during this period, during 1863, the Army of Tennessee retreated through the county, leaving it to Union control thereafter. Isham G. Harris, Confederate governor of Tennessee, was from Franklin County, after being restored to political rights after the war, he was elected to represent the state in the United States Senate. During the temperance agitations of the late 19th century, residents discovered that by a quirk of state law, as a consequence, all of the countys towns abolished their charters in order to prohibit liquor sales. The TVA helped bring new industry to the area and it also created opportunities for water recreation by making new lakes, but many county residents were displaced from their homes in the massive public works project. The establishment of the federal Arnold Engineering Development Center, which lies partly in the county, also helped spur economic growth, although the interstate highway system barely touched the county, it did provide valuable access via Interstate 24 to nearby Chattanooga. Two notable figures who were born in the county early in the century were singer/entertainer Dinah Shore. He later became a British subject and was awarded a knighthood, considerable industrial growth occurred in the county in the last decades of the 20th century, including the construction of a large automobile engine plant by the Nissan corporation in Decherd. An emphasis on tourism also developed, based on Civil War history and local attractions such as the dogwood forests. According to the U. S. Census Bureau, the county has an area of 576 square miles. Franklin is one of Tennessees southern tier of counties and abuts the Alabama border

2010 United States Census
–
The 2010 United States Census, is the twenty-third and currently most recent United States national census. National Census Day, the day used for the census, was April 1,2010. As part of a drive to increase the accuracy,635,000 temporary enumerators were hired. The population of the United States was counted as 308,745,538, as required by the United States Constitution, the U. S. census has been conducted every 10 years since 1790. The 2000 U. S. Census was the previous census completed, participation in the U. S. Census is required by law in Title 13 of the United States Code. On January 25,2010, Census Bureau Director Robert Groves personally inaugurated the 2010 Census enumeration by counting World War II veteran Clifton Jackson, more than 120 million census forms were delivered by the U. S. Post Office beginning March 15,2010, the number of forms mailed out or hand-delivered by the Census Bureau was approximately 134 million on April 1,2010. The 2010 Census national mail participation rate was 74%, from April through July 2010, census takers visited households that did not return a form, an operation called non-response follow-up. In December 2010, the Census Bureau delivered population information to the president for apportionment, personally identifiable information will be available in 2082. The Census Bureau did not use a form for the 2010 Census. In several previous censuses, one in six households received this long form, the 2010 Census used only a short form asking ten basic questions, How many people were living or staying in this house, apartment, or mobile home on April 1,2010. Were there any additional people staying here on April 1,2010 that you did not include in Question 1, mark all that apply, Is this house, apartment, or mobile home – What is your telephone number. What is Person 1s age and Person 1s date of birth, is Person 1 of Hispanic, Latino, or Spanish origin. Does Person 1 sometimes live or stay somewhere else, the form included space to repeat some or all of these questions for up to twelve residents total. In contrast to the 2000 census, an Internet response option was not offered, detailed socioeconomic information collected during past censuses will continue to be collected through the American Community Survey. The survey provides data about communities in the United States on a 1-year or 3-year cycle, depending on the size of the community, rather than once every 10 years. A small percentage of the population on a basis will receive the survey each year. In June 2009, the U. S. Census Bureau announced that it would count same-sex married couples, however, the final form did not contain a separate same-sex married couple option

Central Time Zone
–
The North American Central Time Zone is a time zone in parts of Canada, the United States, Mexico, Central America, some Caribbean Islands, and part of the Eastern Pacific Ocean. Central Standard Time is six hours behind Coordinated Universal Time, during summer most of the zone uses daylight saving time, and changes to Central Daylight Time which is five hours behind UTC. The province of Manitoba is the province or territory in Canada that observes Central Time in all areas. Also, most of the province of Saskatchewan is on Central Standard Time year-round, major exceptions include Lloydminster, a city situated on the boundary between Alberta and Saskatchewan. The city charter stipulates that it shall observe Mountain Time and DST, putting the community on the time as all of Alberta, including the major cities of Calgary. As a result, during the summer, clocks in the province match those in Alberta. The Central Time Zone is the second most populous in the US after the Eastern Time Zone, lanett and Valley observe Eastern Time historically because they were textile mill towns and the original home office of their mills was in West Point, Georgia. Some eastern counties observe Central Time because they are close to the border of the Middle Tennessee counties surrounding the Nashville metropolitan area. Louisiana Michigan, All of Michigan observes Eastern Time except the four Upper Peninsula counties that border Wisconsin, other westernmost counties from this area such as Ontonagon observe Eastern Time. South Dakota, Eastern half as divided by the Missouri river adjacent to the state capital, note, the metropolitan area of Pierre is Central, including Fort Pierre. Wisconsin Most of Mexico—roughly the eastern three-fourths—lies in the Central Time Zone, except for six northwestern states, the federal entities of Mexico that observe Central Time, Belize, Costa Rica, El Salvador, Guatemala, Honduras, and Nicaragua all use Central Standard Time year-round. The Galápagos Islands in Ecuador uses Central Standard Time all year-round, Daylight saving time is in effect in much of the Central time zone between mid-March and early November. The modified time is called Central Daylight Time and is UTC−5, in Canada, Saskatchewan does not observe a time change. One reason that Saskatchewan does not take part in a change is that, geographically. The province elected to move onto permanent daylight saving by being part of the Central Time Zone, Mexico decided not to go along with this change and observes their horario de verano from the first Sunday in April to the last Sunday in October. In December 2009, the Mexican Congress allowed ten border cities, eight of which are in states that observe Central Time, to adopt the U. S. daylight time schedule effective in 2010
