Pavel K. Oshchepkov
Pavel Kondratyevich Oshchepkov (June 24, 1908 – December 1, 1992) was a Soviet physicist who had a leading role in the development of radio-location (radar) in the USSR. During the Great Purge he was sent to a Gulag labor camp for 10 years. Upon release, he began a new life and gained recognition in other scientific areas. Career and accomplishments Pavel (also known as Piotr) Oshchepkov was born in the village of Zuevy Kluchi, Karakulinski district, Udmurtia Republic. A child of the Russian Revolution and the associated strife in life, he lost his parents and, uneducated, roamed the streets until he was 12. He was then placed in school at the Shalashinsk Commune where he first learned to read. By 1928 he was able to enter the Plekhanov Russian Academy of Economics in Moscow to study economics of electrical power. His early performance there was excellent, and he was allowed to transfer to Moscow University, where in 1931 he completed his undergraduate education in the physic ...

Udmurtia
Udmurtia (russian: Удму́ртия, r=Udmúrtiya, p=ʊˈdmurtʲɪjə; udm, Удмуртия, ''Udmurtija''), or the Udmurt Republic (russian: Удмуртская Республика, udm, Удмурт Республика, Удмурт Элькун, ''Udmurt Respublika'', ''Udmurt Eľkun''), is a federal subject of Russia (a republic) in Eastern Europe, within the Volga Federal District. Its capital is the city of Izhevsk. Name The name ''Udmurt'' comes from ('meadow people'), where the first part represents the Permic root or ('meadow, glade, turf, greenery'). This is supported by a document dated 1557, in which the Udmurts are referred to as ('meadow people'), alongside the traditional Russian name . The second part means 'person' (cf. Komi , Mari ). It is probably an early borrowing from a Scythian language: or ('person, man'; cf. Urdu ), which is thought to have been borrowed from the Indo-Aryan term ('man, mortal, one who is bound to die'. cf. Old Indic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Abram Ioffe
Abram Fedorovich Ioffe ( rus, Абра́м Фёдорович Ио́ффе, p=ɐˈbram ˈfʲɵdərəvʲɪtɕ ɪˈofɛ; – 14 October 1960) was a prominent Russian/Soviet physicist. He received the Stalin Prize (1942), the Lenin Prize (1960) (posthumously), and the Hero of Socialist Labor (1955). Ioffe was an expert in various areas of solid state physics and electromagnetism. He established research laboratories for radioactivity, superconductivity, and nuclear physics, many of which became independent institutes. Biography Ioffe was born into a middle-class Jewish family in the small town of Romny, Russian Empire (now in Sumy Oblast, Ukraine). After graduating from Saint Petersburg State Institute of Technology in 1902, he spent two years as an assistant to Wilhelm Röntgen in his Munich laboratory. Ioffe completed his Ph.D. at Munich University in 1905. His dissertation studied the electrical conductivity/electrical stress of dielectric crystals. After 1906, Ioffe worked i ...

Radar Pioneers
Radar is a detection system that uses radio waves to determine the distance (''ranging''), angle, and radial velocity of objects relative to the site. It can be used to detect aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations, and terrain. A radar system consists of a transmitter producing electromagnetic waves in the radio or microwaves domain, a transmitting antenna, a receiving antenna (often the same antenna is used for transmitting and receiving) and a receiver and processor to determine properties of the objects. Radio waves (pulsed or continuous) from the transmitter reflect off the objects and return to the receiver, giving information about the objects' locations and speeds. Radar was developed secretly for military use by several countries in the period before and during World War II. A key development was the cavity magnetron in the United Kingdom, which allowed the creation of relatively small systems with sub-meter resolution. The t ...

Order Of The Red Banner Of Labour
The Order of the Red Banner of Labour (russian: Орден Трудового Красного Знамени, translit=Orden Trudovogo Krasnogo Znameni) was an order of the Soviet Union established to honour great deeds and services to the Soviet state and society in the fields of production, science, culture, literature, the arts, education, health, social and other spheres of labour activities. It is the labour counterpart of the military Order of the Red Banner. A few institutions and factories, being the pride of Soviet Union, also received the order. The Order of the Red Banner of Labour was the third-highest civil award in the Soviet Union, after the Order of Lenin and the Order of the October Revolution. The Order of the Red Banner of Labour began solely as an award of the Russian SFSR on December 28, 1920. The all-Union equivalent was established by Decree of the Presidium of the Supreme Soviet on September 7, 1928, and approved by another decree on September 15, 1 ...

Order Of The October Revolution
The Order of the October Revolution (russian: Орден Октябрьской Революции, ''Orden Oktyabr'skoy Revolyutsii'') was instituted on October 31, 1967, in time for the 50th anniversary of the October Revolution. It was conferred upon individuals or groups for services furthering communism or the state, or in enhancing the defenses of the Soviet Union, military and civil.

Those who were awarded the titles "Hero of the Soviet Union" and " Hero of Socialist Labour" were also given the order as part of the award. It was also bestowed on cities, companies, factories, regions, military units, and ships. Various educational instituti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Entropy
Entropy is a scientific concept, as well as a measurable physical property, that is most commonly associated with a state of disorder, randomness, or uncertainty. The term and the concept are used in diverse fields, from classical thermodynamics, where it was first recognized, to the microscopic description of nature in statistical physics, and to the principles of information theory. It has found far-ranging applications in chemistry and physics, in biological systems and their relation to life, in cosmology, economics, sociology, weather science, climate change, and information systems including the transmission of information in telecommunication. The thermodynamic concept was referred to by Scottish scientist and engineer William Rankine in 1850 with the names ''thermodynamic function'' and ''heat-potential''. In 1865, German physicist Rudolf Clausius, one of the leading founders of the field of thermodynamics, defined it as the quotient of an infinitesimal amount of hea ...

Radiation Spectrum
In physics, radiation is the emission or transmission of energy in the form of waves or particles through space or through a material medium. This includes: * ''electromagnetic radiation'', such as radio waves, microwaves, infrared, visible light, ultraviolet, x-rays, and gamma radiation (γ) * ''particle radiation'', such as alpha radiation (α), beta radiation (β), proton radiation and neutron radiation (particles of non-zero rest energy) * '' acoustic radiation'', such as ultrasound, sound, and seismic waves (dependent on a physical transmission medium) * ''gravitational radiation'', that takes the form of gravitational waves, or ripples in the curvature of spacetime Radiation is often categorized as either ''ionizing'' or ''non-ionizing'' depending on the energy of the radiated particles. Ionizing radiation carries more than 10 eV, which is enough to ionize atoms and molecules and break chemical bonds. This is an important distinction due to the large difference i ...

Thermal Physics
Thermal physics is the combined study of thermodynamics, statistical mechanics, and kinetic theory of gases. This umbrella-subject is typically designed for physics students and functions to provide a general introduction to each of three core heat-related subjects. Other authors, however, define thermal physics loosely as a summation of only thermodynamics and statistical mechanics. Thermal physics can be seen as the study of system with larger number of atom, it unites thermodynamics to statistical mechanics. Overview Thermal physics, generally speaking, is the study of the statistical nature of physical systems from an energetic perspective. Starting with the basics of heat and temperature, thermal physics analyzes the first law of thermodynamics and second law of thermodynamics from the statistical perspective, in terms of the number of microstate (statistical mechanics), microstates corresponding to a given macrostate. In addition, the concept of entropy is studied via Qu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
