Information: - Bratislava (or also known by ) is the capital of Slovakia, and with a population of about 450,000, the country's largest city. The greater metropolitan area is home to more than 650,000 people. Bratislava is in southwestern Slovakia, occupying both banks of the River Danube and the left bank of the River Morava. Bordering Austria and Hungary, it is the only national capital that borders two sovereign states. - World War I (WWI or WW1), also known as the First World War, or the Great War, was a global war originating in Europe that lasted from 28 July 1914 to 11 November 1918. More than 70million military personnel, including 60 million Europeans, were mobilised in one of the largest wars in history. Over nine million combatants and seven million civilians died as a result of the war (including the victims of a number of genocides), a casualty rate exacerbated by the belligerents' technological and industrial sophistication, and the tactical stalemate caused by gruelling trench warfare. It was one of the deadliest conflicts in history, and paved the way for major political changes, including revolutions in many of the nations involved. - Christoph Rudolff ( born 1499 in Jawor , Silesia , died 1545 in Vienna ) was the author of the first German textbook on algebra . From 1517 to 1521 , Rudolff was a student of Henricus Grammateus ( Schreyber from Erfurt ) at the University of Vienna and was the author of a book computing , under the title : Behend und hubsch Rechnung durch die kunstreichen regeln Algebre so gemeinicklich die Coss genent werden ( Nimble and beautiful calculation via the artful rules of algebra ( which ) are so commonly called '' coss '' ) . He introduced the radical symbol ( ) for the square root . It is believed that this was because it resembled a lowercase '' r '' ( for '' radix '' ) , though there is no direct evidence . Cajori only says that a '' dot is the embryo of our present symbol for the square root '' though it is '' possible , perhaps probable '' that Rudolff 's later symbols are not dots but ' r 's . Furthermore , he used the meaningful definition that x0 = 1 . - Algebra (from Arabic ""al-jabr"" meaning "reunion of broken parts") is one of the broad parts of mathematics, together with number theory, geometry and analysis. In its most general form, algebra is the study of mathematical symbols and the rules for manipulating these symbols; it is a unifying thread of almost all of mathematics. As such, it includes everything from elementary equation solving to the study of abstractions such as groups, rings, and fields. The more basic parts of algebra are called elementary algebra, the more abstract parts are called abstract algebra or modern algebra. Elementary algebra is generally considered to be essential for any study of mathematics, science, or engineering, as well as such applications as medicine and economics. Abstract algebra is a major area in advanced mathematics, studied primarily by professional mathematicians. - Hungary is a unitary parliamentary republic in Central Europe. It covers an area of , situated in the Carpathian Basin and bordered by Slovakia to the north, Romania to the east, Serbia to the south, Croatia to the southwest, Slovenia to the west, Austria to the northwest, and Ukraine to the northeast. With about 10 million inhabitants, Hungary is a medium-sized member state of the European Union. The official language is Hungarian, which is the most widely spoken Uralic language in the world. Hungary's capital and largest metropolis is Budapest, a significant economic hub, classified as an Alpha- global city. Major urban areas include Debrecen, Szeged, Miskolc, Pecs and Gyr. - Organization of the Petroleum Exporting Countries (OPEC, , or OPEP in several other languages) is an intergovernmental organization of 13 nations, founded in 1960 in Baghdad by the first five members (Iran, Iraq, Kuwait, Saudi Arabia, Venezuela), and headquartered since 1965 in Vienna. As of 2015, the 13 countries accounted for an estimated 42 percent of global oil production and 73 percent of the world's "proven" oil reserves, giving OPEC a major influence on global oil prices that were previously determined by American-dominated multinational oil companies. - Slovakia, officially the Slovak Republic, is a landlocked country in Central Europe. It is bordered by the Czech Republic and Austria to the west, Poland to the north, Ukraine to the east and Hungary to the south. Slovakia's territory spans about and is mostly mountainous. The population is over 5 million and comprises mostly ethnic Slovaks. The capital and largest city is Bratislava. The official language is Slovak, a member of the Slavic language family. - Geometry (from the ; "geo-" "earth", "-metron" "measurement") is a branch of mathematics concerned with questions of shape, size, relative position of figures, and the properties of space. A mathematician who works in the field of geometry is called a geometer. - Elementary algebra encompasses some of the basic concepts of algebra, one of the main branches of mathematics. It is typically taught to secondary school students and builds on their understanding of arithmetic. Whereas arithmetic deals with specified numbers, algebra introduces quantities without fixed values, known as variables. This use of variables entails a use of algebraic notation and an understanding of the general rules of the operators introduced in arithmetic. Unlike abstract algebra, elementary algebra is not concerned with algebraic structures outside the realm of real and complex numbers. - Silesia (or ; Silesian German: "Schlasing" Silesian: "lnsk" ) is a region of Central Europe located mostly in Poland, with small parts in the Czech Republic and Germany. Its area is about , and its population about 8,000,000. Silesia is located along the Oder river. It consists of Lower Silesia and Upper Silesia. - Vienna is the capital and largest city of Austria and one of the nine states of Austria. Vienna is Austria's primary city, with a population of about 1.8million (2.6million within the metropolitan area, nearly one third of Austria's population), and its cultural, economic, and political centre. It is the 7th-largest city by population within city limits in the European Union. Until the beginning of the 20th century, it was the largest German-speaking city in the world, and before the splitting of the Austro-Hungarian Empire in World War I, the city had 2 million inhabitants. Today, it has the second largest number of German speakers after Berlin. Vienna is host to many major international organizations, including the United Nations and OPEC. The city is located in the eastern part of Austria and is close to the borders of the Czech Republic, Slovakia, and Hungary. These regions work together in a European Centrope border region. Along with nearby Bratislava, Vienna forms a metropolitan region with 3million inhabitants. In 2001, the city centre was designated a UNESCO World Heritage Site. - The European Union (EU) is a political and economic union of member states that are located primarily in Europe. It has an area of , and an estimated population of over 510 million. The EU has developed an internal single market through a standardised system of laws that apply in all member states. EU policies aim to ensure the free movement of people, goods, services, and capital within the internal market, enact legislation in justice and home affairs, and maintain common policies on trade, agriculture, fisheries, and regional development. Within the Schengen Area, passport controls have been abolished. A monetary union was established in 1999 and came into full force in 2002, and is composed of 19 EU member states which use the euro currency. - Jawor is a town in south-western Poland with 24,347 inhabitants (2006).
