Soviet Union
The Soviet Union,. officially the Union of Soviet Socialist Republics. (USSR),. was a transcontinental country that spanned much of Eurasia from 1922 to 1991. A flagship communist state, it was nominally a federal union of fifteen national republics; in practice, both its government and its economy were highly centralized until its final years. It was a one-party state governed by the Communist Party of the Soviet Union, with the city of Moscow serving as its capital as well as that of its largest and most populous republic: the Russian SFSR. Other major cities included Leningrad (Russian SFSR), Kiev (Ukrainian SSR), Minsk ( Byelorussian SSR), Tashkent (Uzbek SSR), Alma-Ata (Kazakh SSR), and Novosibirsk (Russian SFSR). It was the largest country in the world, covering over and spanning eleven time zones. The country's roots lay in the October Revolution of 1917, when the Bolsheviks, under the leadership of Vladimir Lenin, overthrew the Russian Provisional Government ...

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 ...

Scientists From Kropyvnytskyi
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.''''

1950 Births
Year 195 ( CXCV) was a common year starting on Wednesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Scrapula and Clemens (or, less frequently, year 948 '' Ab urbe condita''). The denomination 195 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years. Events By place Roman Empire * Emperor Septimius Severus has the Roman Senate deify the previous emperor Commodus, in an attempt to gain favor with the family of Marcus Aurelius. * King Vologases V and other eastern princes support the claims of Pescennius Niger. The Roman province of Mesopotamia rises in revolt with Parthian support. Severus marches to Mesopotamia to battle the Parthians. * The Roman province of Syria is divided and the role of Antioch is diminished. The Romans annexed the Syrian cities of Edessa and Nisibis. Severus re-establ ...

Difference Equation
In mathematics, a recurrence relation is an equation according to which the nth term of a sequence of numbers is equal to some combination of the previous terms. Often, only k previous terms of the sequence appear in the equation, for a parameter k that is independent of n; this number k is called the ''order'' of the relation. If the values of the first k numbers in the sequence have been given, the rest of the sequence can be calculated by repeatedly applying the equation. In ''linear recurrences'', the th term is equated to a linear function of the k previous terms. A famous example is the recurrence for the Fibonacci numbers, F_n=F_+F_ where the order k is two and the linear function merely adds the two previous terms. This example is a linear recurrence with constant coefficients, because the coefficients of the linear function (1 and 1) are constants that do not depend on n. For these recurrences, one can express the general term of the sequence as a closed-form expression of ...

State Prize Of Ukraine In Science And Technology
The State Prize of Ukraine in Science and Technology is an annual award given by the President of Ukraine for accomplishments in science and technology. It is given for one of four categories: outstanding scientific research in the humanities, social, or natural sciences; development of new equipment, technologies, or methods of disease prevention; the solution of environment problems or invention of new environmental conservation techniques; or textbooks or new vocational techniques. It is the highest award given by The Government of Ukraine for accomplishments in science and technology. Recipients are called Laureates of the State Prize of Ukraine in the field of science and technology. History The State Prize of Ukraine in Science and Technology was established by the Council of Ministers of the Ukrainian SSR in 1969. Winners have been named every year since then (see the list of winners in Ukrainian). The prize is often given to groups of researchers for joint work on one proje ...

Kropyvnytskyi
Kropyvnytskyi ( uk, Кропивницький, Kropyvnytskyi ) is a city in central Ukraine on the Inhul river with a population of . It is an administrative center of the Kirovohrad Oblast. Over its history, Kropyvnytskyi has changed its name several times. The settlement was known as Yelysavethrad ( uk, Єлисаветград, links=no ) after Empress Elizabeth of Russia () from 1752 to 1924 as well as simply Elysavet. In 1924 it became Zinovievsk ( uk, Зінов'євськ, links=no, ) in honour of the Bolshevik revolutionary and Politburo member Grigory Zinoviev (1883-1936), who was born there. Following the assassination of the First Secretary of the Leningrad City Committee of the All-Union Communist Party (Bolsheviks) Sergei Kirov (in office 1926–1934), the town was renamed Kirovo ( uk, Кірово, links=no ) in Kirov's honour on 7 December, 1934—a name-change similar to those of numerous other localities throughout the USSR (including present-day Kirov in Kir ...
