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

North Carolina
–
North Carolina is a state in the southeastern region of the United States. The state borders South Carolina and Georgia to the south, Tennessee to the west, Virginia to the north, North Carolina is the 28th most extensive and the 9th most populous of the U. S. states. The state is divided into 100 counties, the most populous municipality is Charlotte, which is the second largest banking center in the United States after New York City. The state has a range of elevations, from sea level on the coast to 6,684 feet at Mount Mitchell. The climate of the plains is strongly influenced by the Atlantic Ocean. Most of the falls in the humid subtropical climate zone. More than 300 miles from the coast, the western, mountainous part of the state has a highland climate. North Carolina is bordered by South Carolina on the south, Georgia on the southwest, Tennessee on the west, Virginia on the north, the United States Census Bureau places North Carolina in the South Atlantic division of the southern region. So many ships have been lost off Cape Hatteras that the area is known as the Graveyard of the Atlantic, the most famous of these is the Queen Annes Revenge, which went aground in Beaufort Inlet in 1718. The coastal plain transitions to the Piedmont region along the Atlantic Seaboard fall line, the Piedmont region of central North Carolina is the states most populous region, containing the six largest cities in the state by population. It consists of rolling countryside frequently broken by hills or low mountain ridges. The Piedmont ranges from about 300 feet in elevation in the east to about 1,500 feet in the west, the western section of the state is part of the Appalachian Mountain range. Among the subranges of the Appalachians located in the state are the Great Smoky Mountains, Blue Ridge Mountains, the Black Mountains are the highest in the eastern United States, and culminate in Mount Mitchell at 6,684 feet, the highest point east of the Mississippi River. North Carolina has 17 major river basins, the five basins west of the Blue Ridge Mountains flow to the Gulf of Mexico, while the remainder flow to the Atlantic Ocean. Of the 17 basins,11 originate within the state of North Carolina, but only four are contained entirely within the states border – the Cape Fear, the Neuse, the White Oak, and the Tar-Pamlico basin. Elevation above sea level is most responsible for temperature change across the state, the climate is also influenced by the Atlantic Ocean and the Gulf Stream, especially in the coastal plain. These influences tend to cause warmer winter temperatures along the coast, the coastal plain averages around 1 inch of snow or ice annually, and in many years, there may be no snow or ice at all. North Carolina experiences severe weather in summer and winter, with summer bringing threat of hurricanes, tropical storms, heavy rain

Alamance County, North Carolina
–
Alamance County /ˈæləmæns/ is a county located in the U. S. state of North Carolina. As of the 2010 census, the population was 151,131, formed in 1849 from Orange County to the east, Alamance County has been the site of significant historical events, textile manufacturing, and agriculture in North Carolina. Alamance County comprises the Burlington, NC Metropolitan Statistical Area, which is included in the Greensboro-Winston-Salem-High Point. The 2012 estimated population of the area was 153,920. The paths later became the basis of the railroad and interstate highway routes, Great Alamance Creek, and in turn Little Alamance Creek, according to legend, were named after a local Native American word to describe the blue mud that was found at the bottom of the creeks. In the 1780s, the Occaneechi Native Americans returned to North Carolina from Virginia, during the early 19th century, the textile industry grew heavily in the area, and as such, the need for better transportation grew. By the 1840s several mills were set up along the Haw River and near Great Alamance Creek, between 1832 and 1880, there were at least 14 major mills powered by these rivers and streams. Mills were built by the Trollinger, Holt, Newlin, Swepson, one of the mills, built in 1832 by Ben Trollinger, is still in operation. It is owned by Copland Industries and sits in the community of Carolina and is the oldest continuously-operating mill in the state of North Carolina. One of the textiles produced in the area were the Alamance Plaids or Glencoe Plaids used in everything from clothing to tablecloths. The Alamance Plaids manufactured by textile pioneer Edwin M. Holt were the first colored cotton goods produced on power looms in the South, and paved the way for the regions textile boom. But by the late 20th century, most of the plants and mills had now gone out of business, including the mills operated by Burlington Industries, a company that was based in Burlington. By the 1840s, the industry was booming, and the railroad was being built through the area as a convenient link between Raleigh and Greensboro. The county was formed January 29,1849 from Orange County, in March,1861, Alamance County residents voted overwhelmingly against North Carolinas secession from the Union,1,114 to 254. At the time of the convention, around 30% of Alamance Countys population were slaves, overall, North Carolina was reluctant to join other Southern states in secession, the Battle of Fort Sumter in April 1961 changed that. When Lincoln called up troops, Governor John Ellis replied, I can be no party to this violation of the laws of the country. You can get no troops from North Carolina, after a special legislative session, North Carolinas legislature unanimously voted in favor of secession on May 20,1861. No battles took place in the county itself, Alamance County sent its share of soldiers to the front lines

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

Eastern Time Zone
–
Places that use Eastern Standard Time when observing standard time are 5 hours behind Coordinated Universal Time. Eastern Daylight Time, when observing daylight saving time DST is 4 hours behind Coordinated Universal Time, in the northern parts of the time zone, on the second Sunday in March, at 2,00 a. m. EST, clocks are advanced to 3,00 a. m. EDT leaving a one-hour gap, on the first Sunday in November, at 2,00 a. m. EDT, clocks are moved back to 1,00 a. m, southern parts of the zone do not observe daylight saving time. The Uniform Time Act of 1966 ruled that daylight saving time would run from the last Sunday of April until the last Sunday in October in the United States, the act was amended to make the first Sunday in April the beginning of daylight saving time as of 1987. The Energy Policy Act of 2005 extended daylight saving time in the United States beginning in 2007. So local times change at 2,00 a. m. EST to 3,00 a. m. EDT on the second Sunday in March, in Canada, the time changes as it does in the United States. However, a handful of communities unofficially observe Eastern Time because they are part of the Columbus, Georgia metropolitan area – Phenix City, Smiths Station, Lanett, and Valley. Florida, All of Florida is in the Eastern Time zone except for the portion of the Florida Panhandle west of the Apalachicola River, as the Eastern–Central zone boundary approaches the Gulf of Mexico, it follows the Bay/Gulf county line. Indiana, All of Indiana observes Eastern Time except for six counties in the Chicago metropolitan area. Kentucky, Roughly, the half of the state, including all of metropolitan Louisville, is in the Eastern Time Zone. Historically the entire state observed Central Time, when daylight saving time was first introduced, the Lower Peninsula remained on DST after it formally ended, effectively re-aligning itself into the Eastern Time Zone. The Upper Peninsula continued to observe Central Time until 1972, when all, Tennessee, Most of the eastern third of Tennessee is legally on Eastern Time. Eastern Time is also used somewhat as a de facto official time for all of the United States, since it includes the capital and the largest city. Major professional sports leagues also post all game times in Eastern time, for example, a game time between two teams from Pacific Time Zone will still be posted in Eastern time. Most cable television and national broadcast networks advertise airing times in Eastern time, national broadcast networks generally have two primary feeds, an eastern feed for Eastern and Central time zones, and a tape-delayed western feed for the Pacific Time Zone. The prime time is set on Eastern and Pacific at 8,00 p. m. with the Central time zone stations receiving the eastern feed at 7,00 p. m. local time. Mountain Time Zone stations receive a separate feed at 7,00 p. m. local time, as Arizona does not observe daylight saving time, during the summer months, it has its own feed at 7,00 p. m. local time

UTC−05,00 is a time offset that subtracts five hours from Coordinated Universal Time. In North America, it is observed in the Eastern Time Zone during standard time, the western Caribbean uses it year round. The southwestern and northwestern portions of Indiana Mexico – Central Zone Central, in most of Mexico, daylight time starts a few weeks after the United States. Communities on the U. S. border that observe Central Time follow the U. S. daylight time schedule

Daylight saving time
–
Daylight saving time is the practice of advancing clocks during summer months by one hour so that evening daylight lasts an hour longer, while sacrificing normal sunrise times. Typically, regions that use Daylight Savings Time adjust clocks forward one hour close to the start of spring, American inventor and politician Benjamin Franklin proposed a form of daylight time in 1784. New Zealander George Hudson proposed the idea of saving in 1895. The German Empire and Austria-Hungary organized the first nationwide implementation, starting on April 30,1916, many countries have used it at various times since then, particularly since the energy crisis of the 1970s. The practice has both advocates and critics, DST clock shifts sometimes complicate timekeeping and can disrupt travel, billing, record keeping, medical devices, heavy equipment, and sleep patterns. Computer software often adjusts clocks automatically, but policy changes by various jurisdictions of DST dates, industrialized societies generally follow a clock-based schedule for daily activities that do not change throughout the course of the year. The time of day that individuals begin and end work or school, North and south of the tropics daylight lasts longer in summer and shorter in winter, with the effect becoming greater as one moves away from the tropics. However, they will have one hour of daylight at the start of each day. Supporters have also argued that DST decreases energy consumption by reducing the need for lighting and heating, DST is also of little use for locations near the equator, because these regions see only a small variation in daylight in the course of the year. After ancient times, equal-length civil hours eventually supplanted unequal, so civil time no longer varies by season, unequal hours are still used in a few traditional settings, such as some monasteries of Mount Athos and all Jewish ceremonies. This 1784 satire proposed taxing window shutters, rationing candles, and waking the public by ringing church bells, despite common misconception, Franklin did not actually propose DST, 18th-century Europe did not even keep precise schedules. However, this changed as rail transport and communication networks came to require a standardization of time unknown in Franklins day. Modern DST was first proposed by the New Zealand entomologist George Hudson, whose shift work job gave him time to collect insects. An avid golfer, he also disliked cutting short his round at dusk and his solution was to advance the clock during the summer months, a proposal he published two years later. The proposal was taken up by the Liberal Member of Parliament Robert Pearce, a select committee was set up to examine the issue, but Pearces bill did not become law, and several other bills failed in the following years. Willett lobbied for the proposal in the UK until his death in 1915, william Sword Frost, mayor of Orillia, Ontario, introduced daylight saving time in the municipality during his tenure from 1911 to 1912. Starting on April 30,1916, the German Empire and its World War I ally Austria-Hungary were the first to use DST as a way to conserve coal during wartime, Britain, most of its allies, and many European neutrals soon followed suit. Russia and a few other countries waited until the year
