Navahrudak
Novogrudok ( be, Навагрудак, Navahrudak; lt, Naugardukas; pl, Nowogródek; russian: Новогрудок, Novogrudok; yi, נאַוואַראַדאָק, Novhardok, Navaradok) is a town in the Grodno Region, Belarus. In the Middle Ages, the city was ruled by King Mindaugas' son Vaišvilkas. The only mention of a possible Lithuanian early capital of Mindaugas in the contemporaneous sources is Voruta, whose most likely location has been identified as the Šeimyniškėliai mound or hillfort. According to the Lithuanian historian Artūras Dubonis, the claim that Mindaugas' capital was in Novogrudok is false, as they began with the unreliable 16th-century ''Bychowiec Chronicle'', whose claims were repeated a century later by Maciej Stryjkowski. During and after Mindaugas' rule, Novogrudok was part of the Kingdom of Lithuania, and later the Grand Duchy of Lithuania, which was later part of the Polish–Lithuanian Commonwealth. In the 14th century, it was an episcopal se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vilna Governorate
The Vilna Governorate (1795–1915; also known as Lithuania-Vilnius Governorate from 1801 until 1840; russian: Виленская губерния, ''Vilenskaya guberniya'', lt, Vilniaus gubernija, pl, gubernia wileńska) or Government of Vilnius was a governorate (') of the Russian Empire created after the Third Partition of the Polish–Lithuanian Commonwealth in 1795. It was part of the Lithuanian General Governorate, which was called the Vilnius General Governorate after 1830, and was attached to the Northwestern Krai. The seat was in Vilnius (Vilna in Russian), where the Governors General resided. History The first governorates, Vilnius Governorate (consisting of eleven uyezds or districts) and Slonim Governorate, were established after the third partition of the Polish-Lithuanian Commonwealth. Just a year later, on December 12, 1796, by order of Tsar Paul I they were merged into one governorate, called the Lithuanian Governorate, with its capital in Vilnius. By orde ...

Differential Equations
In mathematics, a differential equation is an equation that relates one or more unknown functions and their derivatives. In applications, the functions generally represent physical quantities, the derivatives represent their rates of change, and the differential equation defines a relationship between the two. Such relations are common; therefore, differential equations play a prominent role in many disciplines including engineering, physics, economics, and biology. Mainly the study of differential equations consists of the study of their solutions (the set of functions that satisfy each equation), and of the properties of their solutions. Only the simplest differential equations are solvable by explicit formulas; however, many properties of solutions of a given differential equation may be determined without computing them exactly. Often when a closed-form expression for the solutions is not available, solutions may be approximated numerically using computers. The theory of d ...

Function Of A Real Variable
In mathematical analysis, and applications in geometry, applied mathematics, engineering, and natural sciences, a function of a real variable is a function (mathematics), function whose domain of a function, domain is the real numbers \mathbb, or a subset of \mathbb that contains an interval (mathematics), interval of positive length. Most real functions that are considered and studied are differentiable function, differentiable in some interval. The most widely considered such functions are the real functions, which are the real-valued functions of a real variable, that is, the functions of a real variable whose codomain is the set of real numbers. Nevertheless, the codomain of a function of a real variable may be any set. However, it is often assumed to have a structure of \mathbb-vector space over the reals. That is, the codomain may be a Euclidean space, a coordinate vector, the set of matrix (mathematics), matrices of real numbers of a given size, or an \mathbb-algebra over a ...

Andrey Nikolaevich Kolmogorov
Andrey Nikolaevich Kolmogorov ( rus, Андре́й Никола́евич Колмого́ров, p=ɐnˈdrʲej nʲɪkɐˈlajɪvʲɪtɕ kəlmɐˈɡorəf, a=Ru-Andrey Nikolaevich Kolmogorov.ogg, 25 April 1903 – 20 October 1987) was a Soviet mathematician who contributed to the mathematics of probability theory, topology, intuitionistic logic, turbulence, classical mechanics, algorithmic information theory and computational complexity. Biography Early life Andrey Kolmogorov was born in Tambov, about 500 kilometers south-southeast of Moscow, in 1903. His unmarried mother, Maria Y. Kolmogorova, died giving birth to him. Andrey was raised by two of his aunts in Tunoshna (near Yaroslavl) at the estate of his grandfather, a well-to-do nobleman. Little is known about Andrey's father. He was supposedly named Nikolai Matveevich Kataev and had been an agronomist.

Academic Degree
An academic degree is a qualification awarded to students upon successful completion of a course of study in higher education, usually at a college or university. These institutions commonly offer degrees at various levels, usually including undergraduate degrees, master's, and doctorates, often alongside other academic certificates and professional degrees. The most common undergraduate degree is the bachelor's degree, although in some countries there are lower level higher education qualifications that are also titled degrees (e.g. associate degrees and foundation degrees). History Emergence of the doctor's and master's degrees and the licentiate The doctorate (Latin: ''doceo'' "I teach") appeared in medieval Europe as a license to teach (Latin: ''licentia docendi'') at a medieval university. Its roots can be traced to the early church when the term "doctor" referred to the Apostles, church fathers and other Christian authorities who taught and interpreted the Bible ...
