August Davidov
August Yulevich Davidov (russian: Август Юльевич Давидов) (December 15, 1823 – December 22, 1885) was a Russian mathematician and engineer, professor at Moscow University, and author of works on differential equations with partial derivatives, definite integrals, and the application of probability theory to statistics, and textbooks on elementary mathematics which were repeatedly reprinted from the 1860s to the 1920s. He was president of the Moscow Mathematical Society from 1866 to 1885. Early life and education Davidov was born in Courland where his father was a physician and his younger brother Karl Davidov (1838–1889) became a noted cellist and composer and director of the St. Petersburg Conservatory. In 1839 Davidov was sent to Moscow to attend the school that is now Bauman Moscow State Technical University. In 1841 Davidov enrolled in the Department of Physics and Mathematics at Moscow University, where he studied under Nikolai Brashman (1796–1866) ...

Liepāja
Liepāja (; liv, Līepõ; see #Names and toponymy, other names) is a state city in western Latvia, located on the Baltic Sea. It is the largest-city in the Kurzeme Planning Region, Kurzeme Region and the third-largest city in the country after Riga and Daugavpils. It is an important ice-free port. The population in 2020 was 68,535 people. In the 19th and early 20th century, it was a favourite place for sea-bathers and travellers, with the town boasting a fine park, many pretty gardens and a theatre. Liepāja is however known throughout Latvia as "City where the wind is born", likely because of the constant sea breeze. A song of the same name ( lv, "Pilsētā, kurā piedzimst vējš") was composed by Imants Kalniņš and has become the anthem of the city. Its reputation as the windiest city in Latvia was strengthened with the construction of the largest wind farm in the nation (33 Enercon wind turbines) nearby. The coat of arms of Liepāja was adopted four days after the jurisdic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cadet Corps (Russia)
A Cadet corps (russian: Кадетский корпус, translit=Kadetskiy korpus), historically an admissions-based all-boys military cadets school, prepared boys to become commissioned officers in Imperial Russia. Boys entered a cadet corps between the ages of 8 and 15. History Empress Anna Ivanovna founded the first cadet corps in Saint Petersburg, Russian Empire, in 1731. The term of education was seven years. All instructors had a military rank; they taught a full program of military preparation. In 1766 Catherine the Great's educational reforms broadened the curriculum to include the sciences, philosophy, ethics, history, and international law. A graduate from the corps became a junker and had prime candidacy for a military career. During the October Revolution and the 1917-1923 Russian Civil War, cadets and junkers largely supported the anti-bolshevik White movement. (Distinguish the military cadets of this era from the members of the Constitutional Democratic Party, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scientists From Liepāja
A scientist is a person who conducts scientific research to advance knowledge in an area of the natural sciences. In classical antiquity, there was no real ancient analog of a modern scientist. Instead, philosophers engaged in the philosophical study of nature called natural philosophy, a precursor of natural science. Though Thales (circa 624-545 BC) was arguably the first scientist for describing how cosmic events may be seen as natural, not necessarily caused by gods,Frank N. Magill''The Ancient World: Dictionary of World Biography'', Volume 1 Routledge, 2003 it was not until the 19th century that the term ''scientist'' came into regular use after it was coined by the theologian, philosopher, and historian of science William Whewell in 1833. In modern times, many scientists have advanced degrees in an area of science and pursue careers in various sectors of the economy such as academia, industry, government, and nonprofit environments.''''

Russian Revolution
The Russian Revolution was a period of Political revolution (Trotskyism), political and social revolution that took place in the former Russian Empire which began during the First World War. This period saw Russia abolish its monarchy and adopt a socialist form of government following two successive revolutions and a bloody civil war. The Russian Revolution can also be seen as the precursor for the other European revolutions that occurred during or in the aftermath of WWI, such as the German Revolution of 1918–1919, German Revolution of 1918. The Russian Revolution was inaugurated with the February Revolution in 1917. This first revolt focused in and around the then-capital Petrograd (now Saint Petersburg). After major military losses during the war, the Russian Army had begun to mutiny. Army leaders and high ranking officials were convinced that if Nicholas II of Russia, Tsar Nicholas II abdicated, the domestic unrest would subside. Nicholas agreed and stepped down, usher ...

Nikolai Luzin
Nikolai Nikolaevich Luzin (also spelled Lusin; rus, Никола́й Никола́евич Лу́зин, p=nʲɪkɐˈlaj nʲɪkɐˈlaɪvʲɪtɕ ˈluzʲɪn, a=Ru-Nikilai Nikilayevich Luzin.ogg; 9 December 1883 – 28 January 1950) was a Soviet/Russian mathematician known for his work in descriptive set theory and aspects of mathematical analysis with strong connections to point-set topology. He was the eponym of Luzitania, a loose group of young Moscow mathematicians of the first half of the 1920s. They adopted his set-theoretic orientation, and went on to apply it in other areas of mathematics. Life He started studying mathematics in 1901 at Moscow State University, where his advisor was Dimitri Egorov. He graduated in 1905. Luzin underwent great personal turmoil in the years 1905 and 1906, when his materialistic worldview had collapsed and he found himself close to suicide. In 1906 he wrote to Pavel Florensky, a former fellow mathematics student who was now studying theology: ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mathematics Anthology
Mathematics is an area of knowledge that includes the topics of numbers, formulas and related structures, shapes and the spaces in which they are contained, and quantities and their changes. These topics are represented in modern mathematics with the major subdisciplines of number theory, algebra, geometry, and mathematical analysis, analysis, respectively. There is no general consensus among mathematicians about a common definition for their academic discipline. Most mathematical activity involves the discovery of properties of mathematical object, abstract objects and the use of pure reason to proof (mathematics), prove them. These objects consist of either abstraction (mathematics), abstractions from nature orin modern mathematicsentities that are stipulated to have certain properties, called axioms. A ''proof'' consists of a succession of applications of inference rule, deductive rules to already established results. These results include previously proved theorems, axioms ...

Secondary Schools
A secondary school describes an institution that provides secondary education and also usually includes the building where this takes place. Some secondary schools provide both '' lower secondary education'' (ages 11 to 14) and ''upper secondary education'' (ages 14 to 18), i.e., both levels 2 and 3 of the ISCED scale, but these can also be provided in separate schools. In the US, the secondary education system has separate middle schools and high schools. In the UK, most state schools and privately-funded schools accommodate pupils between the ages of 11–16 or 11–18; some UK private schools, i.e. public schools, admit pupils between the ages of 13 and 18. Secondary schools follow on from primary schools and prepare for vocational or tertiary education. Attendance is usually compulsory for students until age 16. The organisations, buildings, and terminology are more or less unique in each country. Levels of education In the ISCED 2011 education scale levels 2 and 3 c ...
