European Academy Of Sciences And Arts
The European Academy of Sciences and Arts (EASA, la, Academia Scientiarum et Artium Europaea) is a transnational and interdisciplinary network, connecting about 2,000 recommended scientists and artists worldwide, including 37 Nobel Prize laureates. The European Academy of Sciences and Arts is a learned society of scientists and artists, founded by Felix Unger. The academy was founded 1990, is situated in Salzburg and has been supported by the city of Vienna, the government of Austria, and the European Commission. The EASA is now headed by President Klaus Mainzer, TUM Emeritus of Excellence at the Technical University of Munich and Senior Professor at the Carl Friedrich von Weizsäcker Center of the University of Tübingen. It is unrelated to and should not be confused with a different, highly controversial, and less well-established academy, the Belgium-based European Academy of Sciences. It is a member of the InterAcademy Partnership. Its activities have included a collab ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Czechoslovak Academy Of Sciences
The Czechoslovak Academy of Sciences ( Czech: ''Československá akademie věd'', Slovak: ''Česko-slovenská akadémia vied'') was established in 1953 to be the scientific center for Czechoslovakia. It was succeeded by the Czech Academy of Sciences (''Akademie věd České republiky'') and Slovak Academy of Sciences (''Slovenská akadémia vied'') in 1992. History The Royal Czech Society of Sciences, which encompassed both the humanities and the natural sciences, was established in the Czech Crown lands in 1784. After the Communist regime came to power in Czechoslovakia in 1948, all scientific, non-university institutions and learned societies were dissolved and, in their place, the Czechoslovak Academy of Sciences was founded by Act No. 52/1952. It comprised both a complex of research institutes and a learned society. The Slovak Academy of Sciences, established in 1942 and re-established in 1953, was a formal part of the Czechoslovak Academy of Sciences from 1960 to 1992. Dur ...

Russian Academy Of Sciences
The Russian Academy of Sciences (RAS; russian: Росси́йская акаде́мия нау́к (РАН) ''Rossíyskaya akadémiya naúk'') consists of the national academy of Russia; a network of scientific research institutes from across the Russian Federation; and additional scientific and social units such as libraries, publishing units, and hospitals. Peter the Great established the Academy (then the St. Petersburg Academy of Sciences) in 1724 with guidance from Gottfried Leibniz. From its establishment, the Academy benefitted from a slate of foreign scholars as professors; the Academy then gained its first clear set of goals from the 1747 Charter. The Academy functioned as a university and research center throughout the mid-18th century until the university was dissolved, leaving research as the main pillar of the institution. The rest of the 18th century continuing on through the 19th century consisted of many published academic works from Academy scholars and a few Ac ...

USSR State Prize
The USSR State Prize (russian: links=no, Государственная премия СССР, Gosudarstvennaya premiya SSSR) was the Soviet Union's state honor. It was established on 9 September 1966. After the dissolution of the Soviet Union, the prize was followed up by the State Prize of the Russian Federation. The State Stalin Prize ( Государственная Сталинская премия, ''Gosudarstvennaya Stalinskaya premiya''), usually called the Stalin Prize, existed from 1941 to 1954, although some sources give a termination date of 1952. It essentially played the same role; therefore upon the establishment of the USSR State Prize, the diplomas and badges of the recipients of Stalin Prize were changed to that of USSR State Prize. In 1944 and 1945, the last two years of the Second World War, the award ceremonies for the Stalin Prize were not held. Instead, in 1946 the ceremony was held twice: in January for the works created in 1943–1944 and in June for the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Optical Filter
An optical filter is a device that selectively transmits light of different wavelengths, usually implemented as a glass plane or plastic device in the optical path, which are either dyed in the bulk or have interference coatings. The optical properties of filters are completely described by their frequency response, which specifies how the magnitude and phase of each frequency component of an incoming signal is modified by the filter. Filters mostly belong to one of two categories. The simplest, physically, is the absorptive filter; then there are interference or dichroic filters. Many optical filters are used for optical imaging and are manufactured to be transparent; some used for light sources can be translucent. Optical filters selectively transmit light in a particular range of wavelengths, that is, colours, while absorbing the remainder. They can usually pass long wavelengths only (longpass), short wavelengths only (shortpass), or a band of wavelengths, block ...

Laser Science
Laser science or laser physics is a branch of optics that describes the theory and practice of lasers. Laser science is principally concerned with quantum electronics, laser construction, optical cavity design, the physics of producing a population inversion in laser media, and the temporal evolution of the light field in the laser. It is also concerned with the physics of laser beam propagation, particularly the physics of Gaussian beams, with laser applications, and with associated fields such as nonlinear optics and quantum optics. History Laser science predates the invention of the laser itself. Albert Einstein created the foundations for the laser and maser in 1917, via a paper in which he re-derived Max Planck’s law of radiation using a formalism based on probability coefficients ( Einstein coefficients) for the absorption, spontaneous emission, and stimulated emission of electromagnetic radiation. The existence of stimulated emission was confirmed in 1928 by Rudo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
