18th Street NW (Washington, D.C.)
–
18th Street Northwest is a prominent north–south street thoroughfare in the Northwest quadrant of Washington, D. C. The 18th Street roadway was part of the 1791 LEnfant Plan for Washington by Pierre Charles LEnfant, in the present day 18th Street also travels through downtown Washington and the Dupont Circle and Mount Pleasant neighborhoods. It is also one of the streets in the Adams Morgan neighborhood. It passes through the Strivers Section Historic District in the Dupont Circle neighborhood, many bars, nightclubs, and restaurants are located on 18th Street in Adams Morgan, and on weekends it is frequently congested with cars and pedestrians, especially at last call

Washington, D.C.
–
Washington, D. C. formally the District of Columbia and commonly referred to as Washington, the District, or simply D. C. is the capital of the United States. The signing of the Residence Act on July 16,1790, Constitution provided for a federal district under the exclusive jurisdiction of the Congress and the District is therefore not a part of any state. The states of Maryland and Virginia each donated land to form the federal district, named in honor of President George Washington, the City of Washington was founded in 1791 to serve as the new national capital. In 1846, Congress returned the land ceded by Virginia, in 1871. Washington had an population of 681,170 as of July 2016. Commuters from the surrounding Maryland and Virginia suburbs raise the population to more than one million during the workweek. The Washington metropolitan area, of which the District is a part, has a population of over 6 million, the centers of all three branches of the federal government of the United States are in the District, including the Congress, President, and Supreme Court. Washington is home to national monuments and museums, which are primarily situated on or around the National Mall. The city hosts 176 foreign embassies as well as the headquarters of international organizations, trade unions, non-profit organizations, lobbying groups. A locally elected mayor and a 13‑member council have governed the District since 1973, However, the Congress maintains supreme authority over the city and may overturn local laws. D. C. residents elect a non-voting, at-large congressional delegate to the House of Representatives, the District receives three electoral votes in presidential elections as permitted by the Twenty-third Amendment to the United States Constitution, ratified in 1961. Various tribes of the Algonquian-speaking Piscataway people inhabited the lands around the Potomac River when Europeans first visited the area in the early 17th century, One group known as the Nacotchtank maintained settlements around the Anacostia River within the present-day District of Columbia. Conflicts with European colonists and neighboring tribes forced the relocation of the Piscataway people, some of whom established a new settlement in 1699 near Point of Rocks, Maryland. 43, published January 23,1788, James Madison argued that the new government would need authority over a national capital to provide for its own maintenance. Five years earlier, a band of unpaid soldiers besieged Congress while its members were meeting in Philadelphia, known as the Pennsylvania Mutiny of 1783, the event emphasized the need for the national government not to rely on any state for its own security. However, the Constitution does not specify a location for the capital, on July 9,1790, Congress passed the Residence Act, which approved the creation of a national capital on the Potomac River. The exact location was to be selected by President George Washington, formed from land donated by the states of Maryland and Virginia, the initial shape of the federal district was a square measuring 10 miles on each side, totaling 100 square miles. Two pre-existing settlements were included in the territory, the port of Georgetown, Maryland, founded in 1751, many of the stones are still standing

Mathematics
–
Mathematics is the study of topics such as quantity, structure, space, and change. There is a range of views among mathematicians and philosophers as to the exact scope, Mathematicians seek out patterns and use them to formulate new conjectures. Mathematicians resolve the truth or falsity of conjectures by mathematical proof, when mathematical structures are good models of real phenomena, then mathematical reasoning can provide insight or predictions about nature. Through the use of abstraction and logic, mathematics developed from counting, calculation, measurement, practical mathematics has been a human activity from as far back as written records exist. The research required to solve mathematical problems can take years or even centuries of sustained inquiry, rigorous arguments first appeared in Greek mathematics, most notably in Euclids Elements. Galileo Galilei said, The universe cannot be read until we have learned the language and it is written in mathematical language, and the letters are triangles, circles and other geometrical figures, without which means it is humanly impossible to comprehend a single word. Without these, one is wandering about in a dark labyrinth, carl Friedrich Gauss referred to mathematics as the Queen of the Sciences. Benjamin Peirce called mathematics the science that draws necessary conclusions, David Hilbert said of mathematics, We are not speaking here of arbitrariness in any sense. Mathematics is not like a game whose tasks are determined by arbitrarily stipulated rules, rather, it is a conceptual system possessing internal necessity that can only be so and by no means otherwise. Albert Einstein stated that as far as the laws of mathematics refer to reality, they are not certain, Mathematics is essential in many fields, including natural science, engineering, medicine, finance and the social sciences. Applied mathematics has led to entirely new mathematical disciplines, such as statistics, Mathematicians also engage in pure mathematics, or mathematics for its own sake, without having any application in mind. There is no clear line separating pure and applied mathematics, the history of mathematics can be seen as an ever-increasing series of abstractions. The earliest uses of mathematics were in trading, land measurement, painting and weaving patterns, in Babylonian mathematics elementary arithmetic first appears in the archaeological record. Numeracy pre-dated writing and numeral systems have many and diverse. Between 600 and 300 BC the Ancient Greeks began a study of mathematics in its own right with Greek mathematics. Mathematics has since been extended, and there has been a fruitful interaction between mathematics and science, to the benefit of both. Mathematical discoveries continue to be made today, the overwhelming majority of works in this ocean contain new mathematical theorems and their proofs. The word máthēma is derived from μανθάνω, while the modern Greek equivalent is μαθαίνω, in Greece, the word for mathematics came to have the narrower and more technical meaning mathematical study even in Classical times

University
–
A university is an institution of higher education and research which grants academic degrees in various academic disciplines. Universities typically provide undergraduate education and postgraduate education, the word university is derived from the Latin universitas magistrorum et scholarium, which roughly means community of teachers and scholars. Universities were created in Italy and evolved from Cathedral schools for the clergy during the High Middle Ages, the original Latin word universitas refers in general to a number of persons associated into one body, a society, company, community, guild, corporation, etc. Like other guilds, they were self-regulating and determined the qualifications of their members, an important idea in the definition of a university is the notion of academic freedom. The first documentary evidence of this comes from early in the life of the first university, the University of Bologna adopted an academic charter, the Constitutio Habita, in 1158 or 1155, which guaranteed the right of a traveling scholar to unhindered passage in the interests of education. Today this is claimed as the origin of academic freedom and this is now widely recognised internationally - on 18 September 1988,430 university rectors signed the Magna Charta Universitatum, marking the 900th anniversary of Bolognas foundation. The number of universities signing the Magna Charta Universitatum continues to grow, the university is generally regarded as a formal institution that has its origin in the Medieval Christian setting. The earliest universities were developed under the aegis of the Latin Church by papal bull as studia generalia and it is possible, however, that the development of cathedral schools into universities was quite rare, with the University of Paris being an exception. Later they were founded by Kings or municipal administrations. In the early period, most new universities were founded from pre-existing schools. Many historians state that universities and cathedral schools were a continuation of the interest in learning promoted by monasteries, the first universities in Europe with a form of corporate/guild structure were the University of Bologna, the University of Paris, and the University of Oxford. The students had all the power … and dominated the masters, princes and leaders of city governments perceived the potential benefits of having a scholarly expertise develop with the ability to address difficult problems and achieve desired ends. The emergence of humanism was essential to understanding of the possible utility of universities as well as the revival of interest in knowledge gained from ancient Greek texts. The rediscovery of Aristotles works–more than 3000 pages of it would eventually be translated–fuelled a spirit of inquiry into natural processes that had begun to emerge in the 12th century. Some scholars believe that these represented one of the most important document discoveries in Western intellectual history. Richard Dales, for instance, calls the discovery of Aristotles works a turning point in the history of Western thought and this became the primary mission of lecturers, and the expectation of students. The university culture developed differently in northern Europe than it did in the south, Latin was the language of the university, used for all texts, lectures, disputations and examinations. Professors lectured on the books of Aristotle for logic, natural philosophy, and metaphysics, while Hippocrates, Galen, outside of these commonalities, great differences separated north and south, primarily in subject matter

College
–
College is an educational institution or a constituent part of one. A college may be a tertiary educational institution, a part of a collegiate or federal university. In ancient Rome a collegium was a club or society, a group of living together under a common set of rules. Aside from the educational context - nowadays the most common use of college - there are various other meanings also derived from the original Latin term. In the United States, college can be a synonym for university, in Singapore and India, this is known as a junior college. The municipal government of the city of Paris uses the sixth form college as the English name for a lycée. In some national education systems, secondary schools may be called colleges or have college as part of their title, in Australia the term college is applied to any private or independent primary and, especially, secondary school as distinct from a state school. Melbourne Grammar School, Cranbrook School, Sydney and The Kings School, there has also been a recent trend to rename or create government secondary schools as colleges. In the state of Victoria, some high schools are referred to as secondary colleges. Interestingly, the pre-eminent government secondary school for boys in Melbourne is still named Melbourne High School, in Western Australia, South Australia and the Northern Territory, college is used in the name of all state high schools built since the late 1990s, and also some older ones. In New South Wales, some schools, especially multi-campus schools resulting from mergers, are known as secondary colleges. In Queensland some newer schools which accept primary and high school students are styled state college, in Tasmania and the Australian Capital Territory, college refers to the final two years of high school, and the institutions which provide this. In this context, college is an independent of the other years of high school. Here, the expression is a version of matriculation college. This is because these schools have traditionally focused on academic, rather than vocational, subjects. Some private secondary schools choose to use the college in their names nevertheless. Some secondary schools elsewhere in the country, particularly ones within the school system. In New Zealand the word normally refers to a secondary school for ages 13 to 17

High school
–
A secondary school is both an organization that delivers level 2 junior secondary education or level 3 secondary education phases of the ISCED scale, and the building where this takes place. Level 2 junior secondary education is considered to be the second, Secondary schools typically follow on from primary schools and lead into vocational and tertiary education. Attendance is compulsory in most countries for students between the ages 11 and 16, the systems and terminology remain unique to each country. School building design does not happen in isolation, schools need to accommodate students, staff, storage, mechanical and electrical systems, storage, support staff, ancillary staff and administration. The number of rooms required can be determined from the roll of the school. A general classroom for 30 students needs to be 55m2, or more generously 62m2, a general art room for 30 students needs to be 83m2, but 104 m2 for 3D textile work. A drama studio or a specialist science laboratory for 30 needs to be 90 m2, examples are given on how this can be configured for a 1,200 place secondary. The building providing the education has to fulfil the needs of, The students, the teachers, the support staff, the adminstrators. It has to should meet health requirements, minimal functional requirements- such as classrooms, toilets and showers, electricity, textbooks, Government accountants having read the advice then publish minimum guidelines on schools. These enable environmental modelling and establish building costs. Future plans are audited to ensure that standards are not exceeded. The UK government published this downwardly revised space formula in 2014 and it said the floor area should be 1050m² +6. 3m²/pupil place for 11- to 16-year-olds + 7m²/pupil place for post-16s. The external finishes were to be downgraded to meet a build cost of £1113/m², a secondary school, locally may be called high school, junior high school, senior high school. Sweden, gymnasium Switzerland, gymnasium, secondary school, collège or lycée Taiwan, Junior High School, Senior High School, Vocational High School, Military School, in Nigeria, secondary school starts from JSS1 until SSS3. Most students start at the age of 10 or 11 and finish at 16 or 17, Students are required to sit for the West African Senior Secondary Certificate Examination. To progress to university students must obtain at least a credit in Maths, English, in Somalia, secondary school starts from 9th grade until 12th. Students start it when they are around 14 to 15 years of age, Students are required to study Somali and Arabic, with the option of either English or Italian depending on the type of school. Religion, chemistry, physics, biology, physical education, textile, art, design, when secondary school has been completed, students are sent to national training camp before going to either college, or military training. In South Africa, high school begins at grade 8, Students study for five years, at the end of which they write a Matriculation examination

Mathematician
–
A mathematician is someone who uses an extensive knowledge of mathematics in his or her work, typically to solve mathematical problems. Mathematics is concerned with numbers, data, quantity, structure, space, models, one of the earliest known mathematicians was Thales of Miletus, he has been hailed as the first true mathematician and the first known individual to whom a mathematical discovery has been attributed. He is credited with the first use of deductive reasoning applied to geometry, the number of known mathematicians grew when Pythagoras of Samos established the Pythagorean School, whose doctrine it was that mathematics ruled the universe and whose motto was All is number. It was the Pythagoreans who coined the term mathematics, and with whom the study of mathematics for its own sake begins, the first woman mathematician recorded by history was Hypatia of Alexandria. She succeeded her father as Librarian at the Great Library and wrote works on applied mathematics. Because of a dispute, the Christian community in Alexandria punished her, presuming she was involved, by stripping her naked. Science and mathematics in the Islamic world during the Middle Ages followed various models and it was extensive patronage and strong intellectual policies implemented by specific rulers that allowed scientific knowledge to develop in many areas. As these sciences received wider attention from the elite, more scholars were invited and funded to study particular sciences, an example of a translator and mathematician who benefited from this type of support was al-Khawarizmi. A notable feature of many working under Muslim rule in medieval times is that they were often polymaths. Examples include the work on optics, maths and astronomy of Ibn al-Haytham, the Renaissance brought an increased emphasis on mathematics and science to Europe. As time passed, many gravitated towards universities. Moving into the 19th century, the objective of universities all across Europe evolved from teaching the “regurgitation of knowledge” to “encourag productive thinking. ”Thus, seminars, overall, science became the focus of universities in the 19th and 20th centuries. Students could conduct research in seminars or laboratories and began to produce doctoral theses with more scientific content. According to Humboldt, the mission of the University of Berlin was to pursue scientific knowledge. ”Mathematicians usually cover a breadth of topics within mathematics in their undergraduate education, and then proceed to specialize in topics of their own choice at the graduate level. In some universities, a qualifying exam serves to test both the breadth and depth of an understanding of mathematics, the students, who pass, are permitted to work on a doctoral dissertation. Mathematicians involved with solving problems with applications in life are called applied mathematicians. Applied mathematicians are mathematical scientists who, with their knowledge and professional methodology. With professional focus on a variety of problems, theoretical systems

A statistician is someone who works with theoretical or applied statistics. The profession exists in both the private and public sectors and it is common to combine statistical knowledge with expertise in other subjects, and statisticians may work as employees or as statistical consultants. According to the United States Bureau of Labor Statistics, as of 2014,26,970 jobs were classified as statistician in the United States, of these people, approximately 30 percent worked for governments. Statisticians are included with the professions in various national and international occupational classifications, in the United States most employment in the field requires either a masters degree in statistics or a related field or a PhD.

Dupont Circle, Washington, D.C.
–
Dupont Circle is a traffic circle, park, neighborhood, and historic district in Northwest Washington, D. C. The traffic circle is located at the intersection of Massachusetts Avenue NW, Connecticut Avenue NW, New Hampshire Avenue NW, P Street NW, and 19th Street NW. The Dupont Circle neighborhood is bounded approximately by 16th Street NW to the east, 22nd Street NW to the west, M Street NW to the south, the local government Advisory Neighborhood Commission and the Dupont Circle Historic District have slightly different boundaries. The circle is named for Rear Admiral Samuel Francis Du Pont, the area that now constitutes Dupont Circle was once home to a brickyard and slaughterhouse. Improvements made in the 1870s by a board of public works headed by Alexander Boss Shepherd transformed the area into a residential neighborhood. In 1871, the U. S. Army Corps of Engineers began construction of the circle, then called Pacific Circle. On February 25,1882, Congress renamed it Dupont Circle, unveiled on December 20,1884, the statue was sculpted by Launt Thompson, and the circle was landscaped with exotic flowers and ornamental trees. In 1920, the current double-tiered white marble fountain replaced the statue, during the 1870s and 1880s, mansions were built along Massachusetts Avenue, one of Washingtons grand avenues, and townhouses were built throughout the neighborhood. In 1872, the British built a new embassy on Connecticut Avenue, stewarts Castle was built in 1873 on the north side of the circle. By the 1920s, Connecticut Avenue was more commercial in character, some residences, including Senator Philetus Sawyers mansion at Connecticut and R Street, were demolished to make way for office buildings and shops. The Patterson House, at 15 Dupont Circle, served as a residence for President Calvin Coolidge while the actual White House was being repaired in 1927. In 1933, the National Park Service took over administering the circle, Connecticut Avenue was widened in the late 1920s, and increased traffic in the neighborhood caused a great deal of congestion in the circle, making it difficult for pedestrians to get around. Medians were installed in 1948, in the circle, to separate the traffic on Massachusetts Avenue from the local traffic. In 1949 traffic tunnels and a streetcar station were built under the circle as part of the now-defunct Capital Transit project. The tunnels allowed trams and vehicles traveling along Connecticut Avenue to pass more quickly past the circle, when streetcar service ended in 1962, the entrances to the underground station were filled in and paved over, leaving only the traffic tunnel. The neighborhood declined after World War II and particularly after the 1968 riots, the neighborhood took on a bohemian feel and became popular among the gay and lesbian community. D. C. s first gay bookstore, Lambda Rising, opened in 1974, in 1975, the store ran the worlds first gay-oriented television commercial. Gentrification accelerated in the 1980s and 1990s, and the area is now a mainstream and trendy location with coffeehouses, restaurants, bars

JSTOR
–
JSTOR is a digital library founded in 1995. Originally containing digitized back issues of journals, it now also includes books and primary sources. It provides full-text searches of almost 2,000 journals, more than 8,000 institutions in more than 160 countries have access to JSTOR, most access is by subscription, but some older public domain content is freely available to anyone. William G. Bowen, president of Princeton University from 1972 to 1988, JSTOR originally was conceived as a solution to one of the problems faced by libraries, especially research and university libraries, due to the increasing number of academic journals in existence. Most libraries found it prohibitively expensive in terms of cost and space to maintain a collection of journals. By digitizing many journal titles, JSTOR allowed libraries to outsource the storage of journals with the confidence that they would remain available long-term, online access and full-text search ability improved access dramatically. Bowen initially considered using CD-ROMs for distribution, JSTOR was initiated in 1995 at seven different library sites, and originally encompassed ten economics and history journals. JSTOR access improved based on feedback from its sites. Special software was put in place to make pictures and graphs clear, with the success of this limited project, Bowen and Kevin Guthrie, then-president of JSTOR, wanted to expand the number of participating journals. They met with representatives of the Royal Society of London and an agreement was made to digitize the Philosophical Transactions of the Royal Society dating from its beginning in 1665, the work of adding these volumes to JSTOR was completed by December 2000. The Andrew W. Mellon Foundation funded JSTOR initially, until January 2009 JSTOR operated as an independent, self-sustaining nonprofit organization with offices in New York City and in Ann Arbor, Michigan. JSTOR content is provided by more than 900 publishers, the database contains more than 1,900 journal titles, in more than 50 disciplines. Each object is identified by an integer value, starting at 1. In addition to the site, the JSTOR labs group operates an open service that allows access to the contents of the archives for the purposes of corpus analysis at its Data for Research service. This site offers a facility with graphical indication of the article coverage. Users may create focused sets of articles and then request a dataset containing word and n-gram frequencies and they are notified when the dataset is ready and may download it in either XML or CSV formats. The service does not offer full-text, although academics may request that from JSTOR, JSTOR Plant Science is available in addition to the main site. The materials on JSTOR Plant Science are contributed through the Global Plants Initiative and are only to JSTOR

American Mathematical Society
–
The society is one of the four parts of the Joint Policy Board for Mathematics and a member of the Conference Board of the Mathematical Sciences. It was founded in 1888 as the New York Mathematical Society, the brainchild of Thomas Fiske, john Howard Van Amringe was the first president and Fiske became secretary. The society soon decided to publish a journal, but ran into some resistance, the result was the Bulletin of the New York Mathematical Society, with Fiske as editor-in-chief. The de facto journal, as intended, was influential in increasing membership, the popularity of the Bulletin soon led to Transactions of the American Mathematical Society and Proceedings of the American Mathematical Society, which were also de facto journals. In 1891 Charlotte Scott became the first woman to join the society, the society reorganized under its present name and became a national society in 1894, and that year Scott served as the first woman on the first Council of the American Mathematical Society. In 1951, the headquarters moved from New York City to Providence. The society later added an office in Ann Arbor, Michigan in 1984, in 1954 the society called for the creation of a new teaching degree, a Doctor of Arts in Mathematics, similar to a PhD but without a research thesis. Mary W. Gray challenged that situation by sitting in on the Council meeting in Atlantic City, when she was told she had to leave, she refused saying she would wait until the police came. After that time, Council meetings were open to observers and the process of democratization of the Society had begun, julia Robinson was the first female president of the American Mathematical Society but was unable to complete her term as she was suffering from leukemia. In 1988 the Journal of the American Mathematical Society was created, the 2013 Joint Mathematics Meeting in San Diego drew over 6,600 attendees. Each of the four sections of the AMS hold meetings in the spring. The society also co-sponsors meetings with other mathematical societies. The AMS selects a class of Fellows who have made outstanding contributions to the advancement of mathematics. The AMS publishes Mathematical Reviews, a database of reviews of mathematical publications, various journals, in 1997 the AMS acquired the Chelsea Publishing Company, which it continues to use as an imprint.

International Mathematics Olympiad
–
The International Mathematical Olympiad is an annual six-problem mathematical olympiad for pre-college students, and is the oldest of the International Science Olympiads. The first IMO was held in Romania in 1959 and it has since been held annually, except in 1980. About 100 countries send teams of up to six students, plus one team leader, one deputy leader, the selection process differs by country, but it often consists of a series of tests which admit fewer students at each progressing test. Awards are given to approximately the top-scoring 50% of the individual contestants, teams are not officially recognized—all scores are given only to individual contestants, but team scoring is unofficially compared more than individual scores. Contestants must be under the age of 20 and must not be registered at any tertiary institution, subject to these conditions, an individual may participate any number of times in the IMO. The first IMO was held in Romania in 1959, since then it has been held every year except in 1980. That year, it was cancelled due to strife in Mongolia. It was initially founded for eastern European member countries of the Warsaw Pact, under the Soviet bloc of influence, because of this eastern origin, the IMOs were first hosted only in eastern European countries, and gradually spread to other nations. Sources differ about the cities hosting some of the early IMOs, the exact dates cited may also differ, because of leaders arriving before the students, and at more recent IMOs the IMO Advisory Board arriving before the leaders. Several students, such as Zhuoqun Alex Song, Teodor von Burg, Lisa Sauermann, several former participants have won awards such as the Fields Medal. In January 2011, Google gave €1 million to the International Mathematical Olympiad organization, the donation helped the organization cover the costs of the next five global events. The examination consists of six problems, each problem is worth seven points, so the maximum total score is 42 points. The examination is held two consecutive days, each day the contestants have four-and-a-half hours to solve three problems. The problems chosen are from areas of secondary school mathematics, broadly classifiable as geometry, number theory, algebra. They require no knowledge of mathematics such as calculus and analysis. However, they are usually disguised so as to make the solutions difficult, prominently featured are algebraic inequalities, complex numbers, and construction-oriented geometrical problems, though in recent years the latter has not been as popular as before. The Jury aims to order the problems so that the order in increasing difficulty is Q1, Q4, Q2, Q5, Q3, as the leaders know the problems in advance of the contestants, they are kept strictly separated and observed. The selection process for the IMO varies greatly by country, in some countries, especially those in east Asia, the selection process involves several tests of a difficulty comparable to the IMO itself

Ultimately, six high school students are chosen to represent the U. S. at the International Mathematics Olympiad. Allendoerfer Award, Trevor Evans Award, Lester R. Ford Award, George Pólya Award, Merten M. Hasse Award, Henry L. Alder Award, a detailed history of the first fifty years of the MAA appears in May. A report on activities prior to World War II appears in Bennet, further details of its history can be found in Case. In addition numerous regional sections of the MAA have published accounts of their local history, the MAA has for a long time followed a strict policy of inclusiveness and non-discrimination. In previous periods it was subject to the problems of discrimination that were widespread across the United States. M. Holloway came to the meeting and were able to attend the scientific sessions, however, the organizer for the closing banquet refused to honor the reservations of these four mathematicians. Lorch and his colleagues wrote to the bodies of the AMS. Bylaws were not changed, but non-discriminatory policies were established and have been observed since then. The Associations first woman president was Dorothy Lewis Bernstein, the Carriage House that belonged to the residents at 1529 18th Street, N. W. dates to around 1900. It is older than the 5-story townhouse where the MAA Headquarters is currently located, charles Evans Hughes occupied the house while he was Secretary of State and a Supreme Court Justice

World War II
–
World War II, also known as the Second World War, was a global war that lasted from 1939 to 1945, although related conflicts began earlier. It involved the vast majority of the worlds countries—including all of the great powers—eventually forming two opposing alliances, the Allies and the Axis. It was the most widespread war in history, and directly involved more than 100 million people from over 30 countries. Marked by mass deaths of civilians, including the Holocaust and the bombing of industrial and population centres. These made World War II the deadliest conflict in human history, from late 1939 to early 1941, in a series of campaigns and treaties, Germany conquered or controlled much of continental Europe, and formed the Axis alliance with Italy and Japan. Under the Molotov–Ribbentrop Pact of August 1939, Germany and the Soviet Union partitioned and annexed territories of their European neighbours, Poland, Finland, Romania and the Baltic states. In December 1941, Japan attacked the United States and European colonies in the Pacific Ocean, and quickly conquered much of the Western Pacific. The Axis advance halted in 1942 when Japan lost the critical Battle of Midway, near Hawaii, in 1944, the Western Allies invaded German-occupied France, while the Soviet Union regained all of its territorial losses and invaded Germany and its allies. During 1944 and 1945 the Japanese suffered major reverses in mainland Asia in South Central China and Burma, while the Allies crippled the Japanese Navy, thus ended the war in Asia, cementing the total victory of the Allies. World War II altered the political alignment and social structure of the world, the United Nations was established to foster international co-operation and prevent future conflicts. The victorious great powers—the United States, the Soviet Union, China, the United Kingdom, the Soviet Union and the United States emerged as rival superpowers, setting the stage for the Cold War, which lasted for the next 46 years. Meanwhile, the influence of European great powers waned, while the decolonisation of Asia, most countries whose industries had been damaged moved towards economic recovery. Political integration, especially in Europe, emerged as an effort to end pre-war enmities, the start of the war in Europe is generally held to be 1 September 1939, beginning with the German invasion of Poland, Britain and France declared war on Germany two days later. The dates for the beginning of war in the Pacific include the start of the Second Sino-Japanese War on 7 July 1937, or even the Japanese invasion of Manchuria on 19 September 1931. Others follow the British historian A. J. P. Taylor, who held that the Sino-Japanese War and war in Europe and its colonies occurred simultaneously and this article uses the conventional dating. Other starting dates sometimes used for World War II include the Italian invasion of Abyssinia on 3 October 1935. The British historian Antony Beevor views the beginning of World War II as the Battles of Khalkhin Gol fought between Japan and the forces of Mongolia and the Soviet Union from May to September 1939, the exact date of the wars end is also not universally agreed upon. It was generally accepted at the time that the war ended with the armistice of 14 August 1945, rather than the formal surrender of Japan

Nashville, Tennessee
–
Nashville is the capital of the U. S. state of Tennessee and the county seat of Davidson County. It is located on the Cumberland River in the central part of the state. The city is a center for the music, healthcare, publishing, banking and transportation industries and it is known as a center of the country music industry, earning it the nickname Music City, U. S. A. Since 1963, Nashville has had a consolidated city-county government which includes six municipalities in a two-tier system. Nashville is governed by a mayor, vice-mayor, and 40-member Metropolitan Council, thirty-five of the members are elected from single-member districts, five are elected at-large. Reflecting the citys position in government, Nashville is home to the Tennessee Supreme Courts courthouse for Middle Tennessee. According to 2015 estimates from the U. S. Census Bureau, the balance population, which excludes semi-independent municipalities within Nashville, was 654,610. The 2015 population of the entire 13-county Nashville metropolitan area was 1,830,345, the 2015 population of the Nashville-Davidson–Murfreesboro–Columbia combined statistical area, a larger trade area, was 1,951,644. The town of Nashville was founded by James Robertson, John Donelson, and it was named for Francis Nash, the American Revolutionary War hero. Nashville quickly grew because of its location, accessibility as a port on the Cumberland River, a tributary of the Ohio River. By 1800, the city had 345 residents, including 136 African American slaves and 14 free blacks, in 1806, Nashville was incorporated as a city and became the county seat of Davidson County, Tennessee. In 1843, the city was named the permanent capital of the state of Tennessee, by 1860, when the first rumblings of secession began to be heard across the South, antebellum Nashville was a prosperous city. The citys significance as a port made it a desirable prize as a means of controlling important river. In February 1862, Nashville became the first state capital to fall to Union troops, the state was occupied by Union troops for the duration of the war. Within a few years after the Civil War, the Nashville chapter of the Ku Klux Klan was founded by Confederate veteran John W. Morton, meanwhile, the city had reclaimed its important shipping and trading position and developed a solid manufacturing base. The post–Civil War years of the late 19th century brought new prosperity to Nashville and these healthy economic times left the city with a legacy of grand classical-style buildings, which can still be seen around the downtown area. Circa 1950 the state approved a new city charter that provided for the election of city council members from single-member districts. This change was supported because at-large voting diluted the minority populations political power in the city and they could seldom gain a majority of the population to support a candidate of their choice

Charles Evans Hughes, Sr. was an American statesman, lawyer, and Republican politician from New York. He was the Republican nominee in the 1916 U. S, Presidential election, losing narrowly to incumbent President Woodrow Wilson. Historian Clinton Rossiter has hailed him as a leading American conservative, Charles Evans Hughes was born in Glens Falls, New York, the son of a Welsh immigrant minister Rev. David C. Hughes and Mary C. Hughes, a sister of State Senator Henry C and he was active in the Northern Baptist church, a Mainline Protestant denomination. Hughes early education included attending Lafayette School in Newark, NJ, at the age of 14, he enrolled at Madison University, where he became a member of Delta Upsilon fraternity. He then transferred to Brown University, continuing as a member of Delta Upsilon and he graduated third in his class at the age of 19, having been elected to Phi Beta Kappa in his junior year. He read law and entered Columbia Law School in 1882, where he graduated in 1884 with highest honors, in 1885, Hughes met Antoinette Carter, the daughter of a senior partner of the law firm where he worked, and they were married in 1888. They had one son, Charles Evans Hughes Jr. and three daughters and their youngest child, Elizabeth Hughes Gossett, was one of the first humans injected with insulin, and later served as president of the Supreme Court Historical Society. Hughes was the grandfather of Charles Evans Hughes III and H. Stuart Hughes, after graduating Hughes began working for Chamberlain, Carter & Hornblower where he met his future wife. In 1888, shortly after he was married, he became a partner in the firm, later the name was changed to Hughes, Hubbard & Reed. In 1891, Hughes left the practice of law to become a professor at Cornell Law School, in 1893, he returned to his old law firm in New York City to continue practicing until he ran for governor in 1906. He continued his association with Cornell as a lecturer at the Law School from 1893 to 1895. He was also a lecturer for New York University Law School. At that time, in addition to practicing law, Hughes taught at New York Law School with Woodrow Wilson, in 1905, he was appointed as counsel to the New York state legislative Stevens Gas Commission, a committee investigating utility rates. His uncovering of corruption led to lower gas rates in New York City, in 1905, he was appointed to the Armstrong Insurance Commission to investigate the insurance industry in New York as a special assistant to U. S. Attorney General. Hughes served as the Governor of New York from 1907 to 1910 and he defeated William Randolph Hearst in the 1906 election, and was the only Republican statewide candidate to win office. As a supporter of progressive policies, Hughes was able to play on the popularity of Theodore Roosevelt, in 1908, he was offered the vice-presidential nomination by William Howard Taft, but he declined it to run again for Governor. Theodore Roosevelt became an important supporter of Hughes and he pushed the passage of the Moreland Act, which enabled the governor to oversee city and county officials as well as officials in semi-autonomous state bureaucracies

Saunders Mac Lane
–
Saunders Mac Lane was an American mathematician who co-founded category theory with Samuel Eilenberg. Mac Lane was born in Norwich, Connecticut, near where his family lived in Taftville and he was christened Leslie Saunders MacLane, but Leslie fell into disuse because his parents, Donald MacLane and Winifred Saunders, came to dislike it. He began inserting a space into his surname because his first wife found it difficult to type the name without a space and he was the oldest of three brothers, one of his brothers, Gerald MacLane, also became a mathematics professor at Rice University and Purdue University. Another sister died as a baby and his father and grandfather were both ministers, his grandfather had been a Presbyterian, but was kicked out of the church for believing in evolution, and his father was a Congregationalist. His mother, née Winifred Saunders, studied at Mount Holyoke College and taught English, Latin, in high school, Mac Lanes favorite subject was chemistry. While in high school, his father died, and he came under his grandfathers care and his half-uncle, a lawyer, determined to send him to Yale University, where many of his relatives had been educated, and paid his way there beginning in 1926. As a freshman, he became disillusioned with chemistry and his mathematics instructor, Lester S. Hill, coached him for a local mathematics competition which he won, setting the direction for his future work. He went on to study mathematics and physics as a major, taking courses from Jesse Beams, Ernest William Brown, Ernest Lawrence. Northrop, and Øystein Ore, among others and he graduated from Yale with a B. A. in 1930. During this period, he published his first scientific paper, in physics, Mac Lane neglected to actually apply to the program, but showed up and was admitted anyway. His greatest influences there were Paul Bernays and Hermann Weyl, by the time he finished his doctorate in 1934, Bernays had been forced to leave because he was Jewish, and Weyl became his main examiner. At Göttingen, Mac Lane also studied with Gustav Herglotz and Emmy Noether, within days of finishing his degree, he married Dorothy Jones, from Chicago, and soon returned to the U. S. From 1934 through 1938, Mac Lane held short term appointments at Yale University, Harvard University, Cornell University, and he then held a tenure track appointment at Harvard from 1938 to 1947. In 1947, he accepted an offer to return to Chicago and he traveled as a Guggenheim Fellow to ETH Zurich for the 1947–1948 term, where he worked with Heinz Hopf. Mac Lane succeeded Stone as department chair in 1952, and served for six years, Mac Lane was vice president of the National Academy of Sciences and the American Philosophical Society, and president of the American Mathematical Society. While presiding over the Mathematical Association of America in the 1950s and he was a member of the National Science Board, 1974–1980, advising the American government. In 1976, he led a delegation of mathematicians to China to study the conditions affecting mathematics there, Mac Lane was elected to the National Academy of Sciences in 1949, and received the National Medal of Science in 1989. After a thesis in mathematical logic, his work was in field theory

–
Carl Barnett Allendoerfer was an American mathematician in the mid-twentieth century, known for his work in topology and mathematics education. Allendoerfer was born in Kansas City, the son of a prominent banker and he graduated from Haverford College in 1932 and attended New College, Oxford as a Rhodes Scholar, 1932-1934. He received his Ph. D. in mathematics from Princeton University in 1937, Allendoerfer taught at Haverford College in the mid-1940s where he became known for work with André Weil on the Gauss–Bonnet theorem, an important theorem in differential geometry. He continued his studies of differential geometry at the Institute for Advanced Study, Allendoerfer was president of the Mathematical Association of America and editor of its monthly journal. In 1966 he won a Lester R. Ford Award, in 1972, he received the MAAs Award for Distinguished Service to Mathematics. After his death, the MAA established the Carl B, Allendoerfer Award, which is given each year for expository excellence published in Mathematics Magazine. Allendoerfer was a member of Commission on Mathematics of the College Entrance Examination Board whose 1959 report Program for College Preparatory Mathematics outlined many concepts of the New Math. The commission and report were criticized by some for emphasizing pure mathematics in place of traditional and practical considerations like arithmetic. Allendoerfer was the author, with Cletus Oakley, of several prominent mathematics textbooks used in the 1950s and 1960s and he was also author of a series of math films. & Oakley, Cletus O.

Raymond Louis Wilder
–
Raymond Louis Wilder was an American mathematician, who specialized in topology and gradually acquired philosophical and anthropological interests. He played cornet in the orchestra, which performed at dances and fairs. He entered Brown University in 1914, intending to become an actuary, during World War I, he served in the U. S. Navy as an ensign. Brown awarded him his first degree in 1920, and a degree in actuarial mathematics in 1921. That year, he married Una Maude Greene, they had four children, Wilder chose to do his Ph. D. at the University of Texas at Austin, the most fateful decision of his life. Moore was initially unimpressed by the young actuary, but Wilder went on to solve a difficult problem that Moore had posed to his class. Moore suggested Wilder write up the solution for his Ph. D. thesis, Wilder thus became the first of Moores many doctoral students at the University of Texas. After a year as an instructor at Texas, Wilder was appointed assistant professor at the Ohio State University in 1924. In 1926, Wilder joined the faculty of the University of Michigan at Ann Arbor, during the 1930s, he helped settle European refugee mathematicians in the United States. Mathematicians who rubbed shoulders with Wilder at Michigan and who later proved prominent included Samuel Eilenberg, the cofounder of category theory, and the topologist Norman Steenrod. After his 1967 retirement from Michigan at the advanced age of 71, Wilder became a research associate. Wilder was vice president of the American Mathematical Society, 1950–1951, president 1955–1956, and he was president of the Mathematical Association of America, 1965–1966, which awarded him its Distinguished Service Medal in 1973. He was elected to the American National Academy of Sciences in 1963, Brown University and the University of Michigan awarded him honorary doctorates. The mathematics department at the University of California annually bestows one or more graduating seniors with an award in Wilders name, the historical, philosophical, and anthropological writings of Wilders later years suggest a warm, colorful personality. Raymond attests to this having been the case, for instance, was a devoted student of southwestern Native American culture. One day he told me that after retiring he would like to be a bartender in a area of Arizona or New Mexico. Wilders thesis set out a new approach to the Schönflies programme, a positional invariant of a set A with respect to a set B is a property shared by all homeomorphic images of A contained in B. Around 1930, Wilder moved from set-theoretic topology to algebraic topology and he then began an extensive investigation of the theory of manifolds, e. g. his Generalized closed manifolds in n-space, in effect extending the Schönflies programme to higher dimensions

Ivan Morton Niven was a Canadian-American mathematician, specializing in number theory. He did his studies at the University of British Columbia and was awarded his doctorate in 1938 from the University of Chicago. He was a member of the University of Oregon faculty from 1947 to his retirement in 1981 and he received the University of Oregons Charles E. Johnson Award in 1981. Niven completed the solution of most of Warings problem in 1944 and this problem, based on a 1770 conjecture by Edward Waring, consists of finding the smallest number g such that every positive integer is the sum of at most g n th powers of positive integers. David Hilbert had proved the existence of such a g in 1909, Nivens work established the value of g for all and he was president of the Mathematical Association of America from 1983 to 1984. He received the MAA Distinguished Service Award in 1989 and he died in 1999 in Eugene, Oregon. He was honored by being selected to write the Carus Monograph Number 11 and he won a Lester R. Ford Award in 1970. Niven numbers, Nivens constant, and Nivens theorem are named in his honor, also, in 2000 and he has an Erdős number of 1 because he coauthored a paper with Paul Erdős.

Ronald Graham
–
He has done important work in scheduling theory, computational geometry, Ramsey theory, and quasi-randomness. Graham was born in Taft, California, in 1962, he received his Ph. D. in mathematics from the University of California, Berkeley and began working at Bell Labs and later AT&T Labs. He was director of information sciences in AT&T Labs, but retired from AT&T in 1999 after 37 years and his 1977 paper considered a problem in Ramsey theory, and gave a large number as an upper bound for its solution. Graham popularized the concept of the Erdős number, named after the highly prolific Hungarian mathematician Paul Erdős, a scientists Erdős number is the minimum number of coauthored publications away from a publication with Erdős. He co-authored almost 30 papers with Erdős, and was also a good friend, Erdős often stayed with Graham, and allowed him to look after his mathematical papers and even his income. Graham and Erdős visited the young mathematician Jon Folkman when he was hospitalized with brain cancer, between 1993 and 1994 Graham served as the president of the American Mathematical Society. He has published about 320 papers and five books, including Concrete Mathematics with Donald Knuth and he is married to Fan Chung Graham, who is the Akamai Professor in Internet Mathematics at the University of California, San Diego. He has four children, daughters Ché, Laura and Christy, in 2003, Graham won the American Mathematical Societys annual Steele Prize for Lifetime Achievement. The prize was awarded on January 16 that year, at the Joint Mathematics Meetings in Baltimore, in 1999 he was inducted as a Fellow of the Association for Computing Machinery. Graham has won other prizes over the years, he was one of the laureates of the prestigious Pólya Prize the first year it was ever awarded. And the Carl Allendoerfer prize which was established in 1976 for the reasons, however for a different magazine. In 2012 he became a fellow of the American Mathematical Society, with Paul Erdős, Old and new results in combinatorial number theory.

Joseph A. Gallian is an American mathematician, the Morse Alumni Distinguished University Professor of Teaching in the Department of Mathematics and Statistics at the University of Minnesota Duluth. Gallian completed his Ph. D. thesis, entitled Two-Step Centralizers in Finite p-Groups and he has been a professor at the University of Minnesota Duluth since 1972. In addition to teaching classes, he has taught a Humanities course called the The Lives and Music of the Beatles for more than 25 years. Gallian has authored or edited five books and over 100 articles and he earned media attention in 1991 when he determined the methods used by Minnesota and many other states for assigning drivers license numbers. Every summer since 1977, Gallian has run a Research Experience for Undergraduates program at the University of Minnesota Duluth, the program has been funded by the University of Minnesota Duluth grants from the National Science Foundation and the National Security Agency. It is one of the oldest and longest running REUs in the country, as of the end of 2011, the program has had 178 undergraduate participants and has produced more than 180 publications in mainstream professional journals. More than 100 Duluth REU students have received a PhD degree, Gallian served a 2-year term as the President of the Mathematical Association of America starting in January 2007. Gallian has won both the Allendoerfer and Evans awards for exposition from the Mathematical Association of America and was the Polya lecturer for the MAA from 1999 to 2001, in 2011 he received the MAAs Yueh-Gin Gung and Dr. Charles Y. Hu Distinguished Service to Mathematics Award, in 2000, Gallian was named by a Duluth newspaper as one of the 100 Great Duluthians of the 20th Century. In 2012 he became a fellow of the American Mathematical Society, washington, DC, Mathematical Association of America. A dynamic survey of graph labeling, donald J. Albers & Gerald L. Alexanderson.

International Standard Serial Number
–
An International Standard Serial Number is an eight-digit serial number used to uniquely identify a serial publication. The ISSN is especially helpful in distinguishing between serials with the same title, ISSN are used in ordering, cataloging, interlibrary loans, and other practices in connection with serial literature. The ISSN system was first drafted as an International Organization for Standardization international standard in 1971, ISO subcommittee TC 46/SC9 is responsible for maintaining the standard. When a serial with the content is published in more than one media type. For example, many serials are published both in print and electronic media, the ISSN system refers to these types as print ISSN and electronic ISSN, respectively. The format of the ISSN is an eight digit code, divided by a hyphen into two four-digit numbers, as an integer number, it can be represented by the first seven digits. The last code digit, which may be 0-9 or an X, is a check digit. Formally, the form of the ISSN code can be expressed as follows, NNNN-NNNC where N is in the set, a digit character. The ISSN of the journal Hearing Research, for example, is 0378-5955, where the final 5 is the check digit, for calculations, an upper case X in the check digit position indicates a check digit of 10. To confirm the check digit, calculate the sum of all eight digits of the ISSN multiplied by its position in the number, the modulus 11 of the sum must be 0. There is an online ISSN checker that can validate an ISSN, ISSN codes are assigned by a network of ISSN National Centres, usually located at national libraries and coordinated by the ISSN International Centre based in Paris. The International Centre is an organization created in 1974 through an agreement between UNESCO and the French government. The International Centre maintains a database of all ISSNs assigned worldwide, at the end of 2016, the ISSN Register contained records for 1,943,572 items. ISSN and ISBN codes are similar in concept, where ISBNs are assigned to individual books, an ISBN might be assigned for particular issues of a serial, in addition to the ISSN code for the serial as a whole. An ISSN, unlike the ISBN code, is an identifier associated with a serial title. For this reason a new ISSN is assigned to a serial each time it undergoes a major title change, separate ISSNs are needed for serials in different media. Thus, the print and electronic versions of a serial need separate ISSNs. Also, a CD-ROM version and a web version of a serial require different ISSNs since two different media are involved, however, the same ISSN can be used for different file formats of the same online serial

International Standard Book Number
–
The International Standard Book Number is a unique numeric commercial book identifier. An ISBN is assigned to each edition and variation of a book, for example, an e-book, a paperback and a hardcover edition of the same book would each have a different ISBN. The ISBN is 13 digits long if assigned on or after 1 January 2007, the method of assigning an ISBN is nation-based and varies from country to country, often depending on how large the publishing industry is within a country. The initial ISBN configuration of recognition was generated in 1967 based upon the 9-digit Standard Book Numbering created in 1966, the 10-digit ISBN format was developed by the International Organization for Standardization and was published in 1970 as international standard ISO2108. Occasionally, a book may appear without a printed ISBN if it is printed privately or the author does not follow the usual ISBN procedure, however, this can be rectified later. Another identifier, the International Standard Serial Number, identifies periodical publications such as magazines, the ISBN configuration of recognition was generated in 1967 in the United Kingdom by David Whitaker and in 1968 in the US by Emery Koltay. The 10-digit ISBN format was developed by the International Organization for Standardization and was published in 1970 as international standard ISO2108, the United Kingdom continued to use the 9-digit SBN code until 1974. The ISO on-line facility only refers back to 1978, an SBN may be converted to an ISBN by prefixing the digit 0. For example, the edition of Mr. J. G. Reeder Returns, published by Hodder in 1965, has SBN340013818 -340 indicating the publisher,01381 their serial number. This can be converted to ISBN 0-340-01381-8, the check digit does not need to be re-calculated, since 1 January 2007, ISBNs have contained 13 digits, a format that is compatible with Bookland European Article Number EAN-13s. An ISBN is assigned to each edition and variation of a book, for example, an ebook, a paperback, and a hardcover edition of the same book would each have a different ISBN. The ISBN is 13 digits long if assigned on or after 1 January 2007, a 13-digit ISBN can be separated into its parts, and when this is done it is customary to separate the parts with hyphens or spaces. Separating the parts of a 10-digit ISBN is also done with either hyphens or spaces, figuring out how to correctly separate a given ISBN number is complicated, because most of the parts do not use a fixed number of digits. ISBN issuance is country-specific, in that ISBNs are issued by the ISBN registration agency that is responsible for country or territory regardless of the publication language. Some ISBN registration agencies are based in national libraries or within ministries of culture, in other cases, the ISBN registration service is provided by organisations such as bibliographic data providers that are not government funded. In Canada, ISBNs are issued at no cost with the purpose of encouraging Canadian culture. In the United Kingdom, United States, and some countries, where the service is provided by non-government-funded organisations. Australia, ISBNs are issued by the library services agency Thorpe-Bowker
