Context_2 : College dating is the set of behaviors and phenomena centered on the seeking out and the maintenance of romantic relationships in a university setting. It has unique properties that only occur, or occur most frequently, in a campus setting. Such phenomena as hooking up and lavaliering are widely prominent among university and college students. Hooking up is a world wide phenomenon that involves two individuals having a sexual encounter without interest in commitment. Lavaliering is a "pre-engagement" engagement that is a tradition in the Greek life of college campuses. Since fraternities and sororities do not occur much outside of the United States, this occurs, for the most part, only in the US. Technology allows college students to take part in unique ways of finding more partners through social networking. Sites such as Facebook, Twitter, and MySpace allow students to make new friends, and potentially find their spouse. Context_3 : The Aurora Islands was a group of three phantom islands first reported in 1762 by the Spanish merchant ship "Aurora" while sailing from Lima to Cádiz. The Aurora's officers reported sighting them again in 1774. The Spanish ship "San Miguel" fixed their location at 52°37'S, 47°49'W. On 20 February 1794, they were sighted again by a Spanish survey ship, the corvette "Atrevida", which as part of the Alejandro Malaspina circumnavigation had been sent to confirm them. Their reported location was approximately halfway between the Falkland Islands and South Georgia at . The latitude is considered perfect, the longitude was based on the meridian of the astronomical observatory, San Fernando, Cádiz. The islands were last reportedly sighted in 1856, but continued to appear on maps of the South Atlantic until the 1870s. Context_4 : Republic Act No. 5036 was the key for the establishment of Aurora National Agricultural School (ANAS) at Bazal, Maria Aurora, Aurora on March 3, 1969 and was actually opened to the public during the school year 1970–1971. However, the High School did not stay long in Bazal, Maria Aurora, because the whole ANAS populace was transferred to a 5.5 school site in San Joaquin, Maria Aurora, Aurora in 1986 for some reasons favorable to the school populace. Context_5 : Aurora Cable Internet was a Canadian company that provided digital cable television, cable Internet and VOIP service in the towns of Aurora and Oak Ridges, Ontario. Founded by Jim Irvine, Aurora Cable was the town's only cable provider from the time of its inception in 1969 until its eventual takeover in 2008. Along with providing cable service it also produced a series of community-based programs to help inform Aurora residents of local events and services. Some of these shows aired for many years including "Sports Beat" (hosted by Lowell McClenny) and "Our Town" (which was hosted my former Aurora mayor Dick Illingworth). In its final year of broadcast ACI's programming line-up included "Plugged In", "Bookmarks", "Fit & Fabulous", "Sports Beat", "Our Town", "On The Money", "Council In Action", "Body Mind & Spirit", "@aci:The Internet Show" and "Tigers This Week". "Fit & Fabulous" was the only ACI show brought over to continue production with Rogers TV York Region. Context_6 : Little Rock has a humid subtropical climate (Köppen Cfa), with hot, usually humid summers, but subject to drought, primarily in late summer. Summers are usually hot, occasionally extremely hot; winters are short and cool, but with marked temperature variations, as the area is subject to alternating incursions of warm, moist air from the Gulf of Mexico (possibly producing daily high temperatures in the 70s F.) and cold, dry air from Canada (possibly producing daily high temperatures below freezing, 32 F., even in the 20s F.). The Little Rock area has nearly 50 inches of precipitation per year, on average. Little Rock experiences a prolonged spring wet season, with heavy rainfall a distinct possibility from March to May, and a secondary wet season peaking in November and December. On average, August is the driest month, and July through September is the driest period of the year. Little Rock averages more rain than the national average, but also averages more sunny days than the national average. Thunderstorms can occur any month of the year, but are especially frequent and severe in spring, when torrential rainfall, damaging thunderstorm winds, hail, and tornadoes are all significant threats; a secondary severe weather season peaks in November. Snow, sleet and freezing rain are rare, but can occur during the winter season, when cold Canadian air at ground level is overrun by warm, moist air from the Gulf of Mexico. Unless otherwise indicated, all normal data presented below are based on data at Bill and Hillary Clinton National Airport the official Little Rock climatology station, from the 1981−2010 normals period. Context_7 : An elastic collision is an encounter between two bodies in which the total kinetic energy of the two bodies after the encounter is equal to their total kinetic energy before the encounter. Perfectly elastic collisions occur only if there is no net conversion of kinetic energy into other forms (such as heat or noise) and therefore they do not normally occur in reality. Context_8 : The AuroraMax project is an outreach and education initiative carried out by the combined effort of The Canadian Space Agency, Astronomy North, University of Calgary and The city of Yellowknife in Yellowknife Northwest Territories. The AuroraMax provides a place to explore and discover the wonder and science behind phenomena such as sunspots, Earth's magnetic field, space weather and the magnificent Northern lights of Canada. Auroras are natural exhibition of lights in the sky that can be seen by the naked eyes. Auroras happen when protons and electrons or charged particles and gases in the Earth's atmosphere crash into each other, creating tiny flares of light that decorate the sky with colorful light. Billions of these tiny flares occur in sequence causing the lights to seem like they are dancing or moving. The lights in the Northern hemisphere are called Aurora Borealis or simply The Northern Lights while the lights in the Southern hemisphere are called Aurora Australis or simply The Southern Lights. Context_9 : The Aurora, Texas, UFO incident reportedly occurred on April 17, 1897 when, according to locals, a UFO crashed on a farm near Aurora, Texas. The incident (similar to the more famous Roswell UFO incident 50 years later) is claimed to have resulted in a fatality from the crash and the alleged alien body is to have been buried in an unmarked grave at the local cemetery. Context_10 : The Aurora Pyramid of Hope is a collection of 296 natural diamonds in a wide variety of colors, billed as "the most comprehensive natural color diamond collection in the world". It is owned by Aurora Gems, Inc., a diamond merchant specialising in fancy color diamonds. The collection has been displayed on loan in a pyramid-shaped display case in various major museums since 1998. Aurora Gems was founded by Harry Rodman (1909–2008) a gold refiner from the Bronx, and Alan Bronstein, a diamond dealer from New Jersey, who began collecting colored diamonds in 1979. After Rodman's death, ownership of the collection became the subject of a dispute between Bronstein and Rodman's heirs, including Rodman's wife, who was also Bronstein's mother. fact_1 : The Aurora Encounter is a 1986 American Weird Western science fiction film directed by the Jim McCullough Sr., written by Melody Brooke and Jim McCullough, Jr., and starring Jack Elam, Mickey Hays, Peter Brown, Carol Bagdasarian and Dottie West. fact_2 :  It was based on the Aurora, Texas, UFO incident. fact_3 : The Aurora, Texas, UFO incident reportedly occurred on April 17, 1897 when, according to locals, a UFO crashed on a farm near Aurora, Texas.
