Sergey Lebedev (scientist)
Sergey Alekseyevich Lebedev (; 2 November, 1902 – 3 July, 1974) was a Soviet scientist in the fields of electrical engineering and computer science, and designer of the first Soviet computers. Biography Lebedev was born in Nizhny Novgorod, Russian Empire. He graduated from Bauman Moscow State Technical University, Moscow Highest Technical School in 1928. From then until 1946 he worked at All-Union Electrotechnical Institute (formerly a division of MSTU) in Moscow and Kyiv. In 1939 he was awarded the degree of Doctor of Sciences for the development of the theory of "artificial stability" of electrical systems. During World War II, Lebedev worked in the field of control automation of complex systems. His group designed a weapon-aiming stabilization system for tanks and an automatic guidance system for airborne missiles. To perform these tasks Lebedev developed an analog computer system to solve ordinary differential equations. From 1946 to 1951 he headed the NASU Institute of ...

Analog Computer
An analog computer or analogue computer is a type of computation machine (computer) that uses physical phenomena such as Electrical network, electrical, Mechanics, mechanical, or Hydraulics, hydraulic quantities behaving according to the mathematical principles in question (''analog signals'') to Scientific modelling, model the problem being solved. In contrast, digital computers represent varying quantities symbolically and by discrete values of both time and amplitude (digital signals). Analog computers can have a very wide range of complexity. Slide rules and nomograms are the simplest, while naval gunfire control computers and large hybrid digital/analog computers were among the most complicated. Complex mechanisms for process control and protective relays used analog computation to perform control and protective functions. Analog computers were widely used in scientific and industrial applications even after the advent of digital computers, because at the time they were ...

Academic Staff Of The Moscow Institute Of Physics And Technology
An academy (Attic Greek: Ἀκαδήμεια; Koine Greek Ἀκαδημία) is an institution of tertiary education. The name traces back to Plato's school of philosophy, founded approximately 386 BC at Akademia, a sanctuary of Athena, the goddess of wisdom and skill, north of Athens, Greece. The Royal Spanish Academy defines academy as scientific, literary or artistic society established with public authority and as a teaching establishment, public or private, of a professional, artistic, technical or simply practical nature. Etymology The word comes from the ''Academy'' in ancient Greece, which derives from the Athenian hero, '' Akademos''. Outside the city walls of Athens, the gymnasium was made famous by Plato as a center of learning. The sacred space, dedicated to the goddess of wisdom, Athena, had formerly been an olive grove, hence the expression "the groves of Academe". In these gardens, the philosopher Plato conversed with followers. Plato developed his session ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
People From Nizhny Novgorod
The term "the people" refers to the public or common mass of people of a polity. As such it is a concept of human rights law, international law as well as constitutional law, particularly used for claims of popular sovereignty. In contrast, a people is any plurality of persons considered as a whole. Used in politics and law, the term "a people" refers to the collective or community of an ethnic group or nation. Concepts Legal Chapter One, Article One of the Charter of the United Nations states that "peoples" have the right to self-determination. Though the mere status as peoples and the right to self-determination, as for example in the case of Indigenous peoples (''peoples'', as in all groups of indigenous people, not merely all indigenous persons as in ''indigenous people''), does not automatically provide for independent sovereignty and therefore secession. Indeed, judge Ivor Jennings identified the inherent problems in the right of "peoples" to self-determination, as i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

History Of Computing Hardware
The history of computing hardware spans the developments from early devices used for simple calculations to today's complex computers, encompassing advancements in both analog and digital technology. The first aids to computation were purely mechanical devices which required the operator to set up the initial values of an elementary arithmetic operation, then manipulate the device to obtain the result. In later stages, computing devices began representing numbers in continuous forms, such as by distance along a scale, rotation of a shaft, or a specific voltage level. Numbers could also be represented in the form of digits, automatically manipulated by a mechanism. Although this approach generally required more complex mechanisms, it greatly increased the precision of results. The development of transistor technology, followed by the invention of integrated circuit chips, led to revolutionary breakthroughs. Transistor-based computers and, later, integrated circuit-based computers ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Novodevichy Cemetery
Novodevichy Cemetery () is a cemetery in Moscow. It lies next to the southern wall of the 16th-century Novodevichy Convent, which is the city's third most popular tourist site. History The cemetery was designed by Ivan Mashkov and inaugurated in 1898. Its importance dates from the 1930s, when the necropolises of the medieval Muscovite monasteries (Simonov Monastery, Simonov, Danilov Monastery, Danilov, Donskoy Monastery, Donskoy) were scheduled for demolition. Only the Donskoy survived the Joseph Stalin era relatively intact. The remains of many famous Russians buried in other abbeys, such as Nikolai Gogol and Sergey Aksakov, were disinterred and reburied at the Novodevichy. A 19th-century necropolis within the walls of the Novodevichy convent, which contained the graves of about 2000 Russian noblemen and university professors, also underwent reconstruction. The vast majority of graves were destroyed. It was at that time that the remains of Anton Chekhov were moved outside the ...
