Information: - The University of Oslo, until 1939 named the Royal Frederick University, is the oldest university in Norway, located in the Norwegian capital of Oslo. Until 1 January 2016 it was the largest Norwegian institution of higher education in terms of size, now surpassed only by the Norwegian University of Science and Technology. The Academic Ranking of World Universities has ranked it the 58th best university in the world and the third best in the Nordic countries. In 2015, the Times Higher Education World University Rankings ranked it the 135th best university in the world and the seventh best in the Nordics. While in its 2016, Top 200 Rankings of European universities, the Times Higher Education listed the University of Oslo at 63rd, making it the highest ranked Norwegian university. - The Norwegian University of Science and Technology (abbreviated NTNU) is a public research university with campuses in the cities of Trondheim, Gjvik and Alesund in Norway. NTNU is the largest of the eight universities in Norway, and, as its name suggests, has the main national responsibility for higher education in engineering and technology. In addition to engineering and the natural and physical sciences, the university offers advanced degrees in other academic disciplines ranging from the social sciences, the arts, medicine and health sciences, teacher education, architecture and fine art. - Academic Ranking of World Universities (ARWU), also known as Shanghai Ranking, is an annual publication of university rankings by Shanghai Ranking Consultancy. The league table was originally compiled and issued by Shanghai Jiaotong University in 2003, the first global ranking with multifarious indicators, after which a board of international advisories was established to provide suggestions. The publication currently includes world's overall and subject league tables, alongside independent regional "Greater China Ranking" and "Macedonian HEIs Ranking". ARWU is regarded as one of the three most influential and widely observed university measures, alongside "QS World University Rankings" and "Times Higher Education World University Rankings". It is praised for its objective methodology but draws some condemnation for narrowly focusing on raw research power, undermining humanities and quality of instruction. - Education is the process of facilitating learning, or the acquisition of knowledge, skills, values, beliefs, and habits. Educational methods include storytelling, discussion, teaching, training, and directed research. Education frequently takes place under the guidance of educators, but learners may also educate themselves. Education can take place in formal or informal settings and any experience that has a formative effect on the way one thinks, feels, or acts may be considered educational. The methodology of teaching is called pedagogy. - Arabic (' or ' ) is a Central Semitic language that was first spoken in Iron Age northwestern Arabia and is now the "lingua franca" of the Arab world. Arabic also is a liturgical language of 1.7 billion Muslims. It is one of six official languages of the United Nations. It is named after the Arabs, a term initially used to describe peoples living from Mesopotamia in the east to the Anti-Lebanon mountains in the west, and from northwestern Arabia to the Sinai in the south. - Science is a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe. - Times Higher Education World University Rankings is an annual publication of university rankings by "Times Higher Education (THE)" magazine. The publisher had collaborated with Quacquarelli Symonds (QS) to publish the joint "THEQS World University Rankings" from 2004 to 2009 before it turned to Thomson Reuters for a new ranking system. The publication now comprises the world's overall, subject, and reputation rankings, alongside three regional league tables, "Asia", "Latin America", and "BRICS & Emerging Economies" which are generated by consistent methodology. It is considered as one of the most widely observed university measures together with "Academic Ranking of World Universities" and "QS World University Rankings". It is praised for having a new improved methodology but undermining non-English-instructing institutions and being commercialized are the major criticisms. - 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. - Geir Ellingsrud ( born 29 November 1948 ) is professor of mathematics at the University of Oslo , where he specialises in algebra and algebraic geometry . He took the cand.real . degree at the University of Oslo in 1973 , and the doctorate at Stockholm University in 1982 . He was a lecturer at Stockholm University from 1982 to 1984 , associate professor at the University of Oslo from 1984 to 1989 , professor at the University of Bergen from 1989 to 1993 and at the University of Oslo since 1993 . He has been a visiting scholar in Nice , Paris , Bonn and Chicago . He has edited the journals Acta Mathematica and Normat . In 2005 Ellingsrud was elected to be rector of the University of Oslo for the period 2006 - 2009 . His team also consisted of Inga Bostad and Haakon Breien Benestad . He did not seek reelection to a second term , and was succeeded by Ole Petter Ottersen . - 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. - Expert is defined differently in varying academic fields. Psychology defines an expert using superior performance; sociology considers that expertise is a label given to an individual by a group and is interested in the power held by experts; philosophy stresses the kind of knowledge held by experts but not novices. Informally, an expert is someone widely recognized as a reliable source of technique or skill whose faculty for judging or deciding rightly, justly, or wisely is accorded authority and status by peers or the public in a specific well-distinguished domain. An expert, more generally, is a person with extensive knowledge or ability based on research, experience, or occupation and in a particular area of study. Experts are called in for advice on their respective subject, but they do not always agree on the particulars of a field of study. An expert can be believed, by virtue of credential, training, education, profession, publication or experience, to have special knowledge of a subject beyond that of the average person, sufficient that others may officially (and legally) rely upon the individual's opinion. Historically, an expert was referred to as a sage (Sophos). The individual was usually a profound thinker distinguished for wisdom and sound judgment. - 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. - Professor (commonly abbreviated as "prof.") is an academic rank at universities and other post-secondary education and research institutions in most countries. Literally, "professor" derives from Latin as a "person who professes" being usually an expert in arts or sciences, a teacher of the highest rank.
