Tunkhannock Viaduct
–
Tunkhannock Creek Viaduct is a concrete deck arch bridge that spans Tunkhannock Creek in Nicholson, Pennsylvania, in the United States. Built by the Delaware, Lackawanna and Western Railroad, the bridge is owned today by Norfolk Southern and is used daily for regular freight service. The contractor was Flickwir & Bush, including general manager F. M. Talbot, construction on the bridge began in May 1912 by excavating all 11 bridge piers to bedrock, which was up to 138 feet below ground. In total, excavation for the viaduct removed 13,318,000 cubic yards of material, almost half of the bulk of the bridge is underground. The steel estimate proved accurate, the bridge used a bit less concrete than expected,167,000 cubic yards. The bridge was dedicated on November 6,1915, along with the opening of the Nicholson Cutoff, construction photos along with a short history of the bridge were published by the Nicholson Area Library in a brochure in 1976. It was listed on the National Register of Historic Places on April 11,1977, since 1990, the local community has celebrated the building of the bridge on the second Sunday of September with Nicholson Bridge Day, a street fair, parade, and other activities. The 100th-anniversary celebration was held in September 2015, Lackawanna cutoff List of bridges documented by the Historic American Engineering Record in Pennsylvania Plowden, David.

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

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

United States Census Bureau
–
The United States Census Bureau is a principal agency of the U. S. Federal Statistical System, responsible for producing data about the American people and economy. The Census Bureaus primary mission is conducting the U. S. Census every ten years, in addition to the decennial census, the Census Bureau continually conducts dozens of other censuses and surveys, including the American Community Survey, the U. S. Economic Census, and the Current Population Survey, furthermore, economic and foreign trade indicators released by the federal government typically contain data produced by the Census Bureau. The Bureaus various censuses and surveys help allocate over $400 billion in federal funds every year and help states, local communities, the Census Bureau is part of the U. S. Department of Commerce and its director is appointed by the President of the United States. The Census Bureau now conducts a population count every 10 years in years ending with a 0. Between censuses, the Census Bureau makes population estimates and projections, the Census Bureau is mandated with fulfilling these obligations, the collecting of statistics about the nation, its people, and economy. The Census Bureaus legal authority is codified in Title 13 of the United States Code, the Census Bureau also conducts surveys on behalf of various federal government and local government agencies on topics such as employment, crime, health, consumer expenditures, and housing. Within the bureau, these are known as surveys and are conducted perpetually between and during decennial population counts. The Census Bureau also conducts surveys of manufacturing, retail, service. Between 1790 and 1840, the census was taken by marshals of the judicial districts, the Census Act of 1840 established a central office which became known as the Census Office. Several acts followed that revised and authorized new censuses, typically at the 10-year intervals, in 1902, the temporary Census Office was moved under the Department of Interior, and in 1903 it was renamed the Census Bureau under the new Department of Commerce and Labor. The department was intended to consolidate overlapping statistical agencies, but Census Bureau officials were hindered by their role in the department. An act in 1920 changed the date and authorized manufacturing censuses every 2 years, in 1929, a bill was passed mandating the House of Representatives be reapportioned based on the results of the 1930 Census. In 1954, various acts were codified into Title 13 of the US Code, by law, the Census Bureau must count everyone and submit state population totals to the U. S. President by December 31 of any year ending in a zero. States within the Union receive the results in the spring of the following year, the United States Census Bureau defines four statistical regions, with nine divisions. The Census Bureau regions are widely used. for data collection, the Census Bureau definition is pervasive. Title 13 of the U. S. Code establishes penalties for the disclosure of this information, all Census employees must sign an affidavit of non-disclosure prior to employment. The Bureau cannot share responses, addresses or personal information with anyone including United States or foreign government, only after 72 years does the information collected become available to other agencies or the general public

1890 United States Census
–
The Eleventh United States Census was taken beginning June 2,1890. The data was tabulated by machine for the first time, the data reported that the distribution of the population had resulted in the disappearance of the American frontier. Data was entered on a machine readable medium, punched cards, the total population of 62,947,714, the family, or rough, count, was announced after only six weeks of processing. The public reaction to this tabulation was disbelief, as it was believed that the right answer was at least 75,000,000. The United States census of 1890 showed a total of 248,253 Native Americans living in America, down from 400,764 Native Americans identified in the census of 1850. The 1890 census announced that the region of the United States no longer existed. Up to and including the 1880 census, the country had a frontier of settlement, by 1890, isolated bodies of settlement had broken into the unsettled area to the extent that there was hardly a frontier line. This prompted Frederick Jackson Turner to develop his Frontier Thesis, the original data for the 1890 Census is no longer available. Almost all the schedules were damaged in a fire in the basement of the Commerce Building in Washington. Some 25% of the materials were presumed destroyed and another 50% damaged by smoke, the damage to the records led to an outcry for a permanent National Archives. The Librarian was asked by the Bureau to identify any records which should be retained for historical purposes, congress authorized destruction of that list of records on February 21,1933, and the surviving original 1890 census records were destroyed by government order by 1934 or 1935. The other censuses for which information has been lost are the 1800 and 1810 enumerations. Mayo-Smith, Richmond, The Eleventh Census of the United States
