Sergei Rytov
Sergei Mikhailovich Rytov (; 3 July 1908 – 22 October 1996) was a Soviet physicist and member of the Russian Academy of Sciences. Rytov contributed to the fields of statistical radiophysics, and fluctuational electrodynamics. The Rytov number for laser propagation in the atmosphere and the Rytov approximation for wave propagation in inhomogeneous media bear his name. Life Sergei Mikhailovich Rytov was born in Kharkov, Russian Empire in 1908. Rytov graduated from Moscow State University (MGU) in 1930, and continued his studies as a post-graduate at MGU's Research Institute of Physics, which he completed in 1933. Later, Rytov worked at the Gorky Research Institute for Engineering Physics (1932–1934), the Lebedev Physical Institute (1934–1938), and finally in the Mints Institute of Radio Engineering until his death. He also lectured in MGU (1930 –1932 and 1934–1938), in the Gorky State University (1932–1934 and 1945–1947) and in the and at the Moscow Institute of ...

Order Of The Red Banner Of Labour
The Order of the Red Banner of Labour () 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, sports, 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, 1928. The Order's statute and regulations were modified by multiple successive decrees of the Presidium of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Scientists From Kharkiv
A scientist is a person who researches 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 ( 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. History The roles of "scientists", and their predecessors before the emergence of modern scientific disciplines, have evolved considerably over time. Scientists of different eras (and before them, natural philosophers, mathematicians, natur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

USSR State Prize
The USSR State Prize () was one of the Soviet Union’s highest civilian honours, awarded from its establishment in September 1966 until the dissolution of the USSR in 1991. It recognised outstanding contributions in the fields of science, mathematics, literature, the arts, and architecture. History State Stalin Prize (1941–1956) The award traces its origins to the State Stalin Prize (), commonly known as the Stalin Prize, which was established in 1941. It honoured achievements in science, technology, literature, and the arts deemed vital to the Soviet war effort and postwar reconstruction.Volkov, Solomon; Bouis, Antonina W., trans. 2004.

Order Of The Badge Of Honour
The Order of the Badge of Honour () was a civilian award of the Soviet Union. It was established on 25 November 1935, and was conferred on citizens of the USSR for outstanding achievements in sports, production, scientific research and social, cultural and other forms of social activity; for promotion of economic, scientific, technological, cultural and other ties between the USSR and other countries; and also for significant contribution to basic and applied research. The order was awarded 1,574,368 times. The "Order of the Badge of Honour" was replaced by the "Order of Honour" () by a Decree of the Presidium of the USSR on 28 December 1988. Following the USSR dissolution, it was replaced by the " Order of Honour" of Russia, established by Presidential Decree no. 442 of 2 March 1994.Ельцин, Б.Н.

Near-field Radiative Heat Transfer
Near-field radiative heat transfer (NFRHT) is a branch of radiative heat transfer which deals with situations for which the objects and/or distances separating objects are comparable or smaller in scale or to the dominant wavelength of thermal radiation exchanging thermal energy. In this regime, the assumptions of geometrical optics inherent to classical radiative heat transfer are not valid and the effects of diffraction, interference, and tunneling of electromagnetic waves can dominate the net heat transfer. These "near-field effects" can result in heat transfer rates exceeding the blackbody limit of classical radiative heat transfer. History The origin of the field of NFRHT is commonly traced to the work of Sergei M. Rytov in the Soviet Union. Rytov examined the case of a semi-infinite absorbing body separated by a vacuum gap from a near-perfect mirror at zero temperature. He treated the source of thermal radiation as randomly fluctuating electromagnetic fields. Later in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
