Optical Telescope
An optical telescope is a telescope that gathers and focuses light mainly from the visible part of the electromagnetic spectrum, to create a magnified image for direct visual inspection, to make a photograph, or to collect data through electronic image sensors. There are three primary types of optical telescope: * Refracting telescopes, which use lenses and less commonly also prisms ( dioptrics) * Reflecting telescopes, which use mirrors ( catoptrics) * Catadioptric telescopes, which combine lenses and mirrors An optical telescope's ability to resolve small details is directly related to the diameter (or aperture) of its objective (the primary lens or mirror that collects and focuses the light), and its light-gathering power is related to the area of the objective. The larger the objective, the more light the telescope collects and the finer detail it resolves. People use optical telescopes (including monoculars and binoculars) for outdoor activities such as obs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Astronomical Observatories In The Czech Republic
Astronomy () is a natural science that studies celestial objects and phenomena. It uses mathematics, physics, and chemistry in order to explain their origin and evolution. Objects of interest include planets, moons, stars, nebulae, galaxies, and comets. Relevant phenomena include supernova explosions, gamma ray bursts, quasars, blazars, pulsars, and cosmic microwave background radiation. More generally, astronomy studies everything that originates beyond Earth's atmosphere. Cosmology is a branch of astronomy that studies the universe as a whole. Astronomy is one of the oldest natural sciences. The early civilizations in recorded history made methodical observations of the night sky. These include the Babylonians, Greeks, Indians, Egyptians, Chinese, Maya, and many ancient indigenous peoples of the Americas. In the past, astronomy included disciplines as diverse as astrometry, celestial navigation, observational astronomy, and the making of calendars. Nowadays, professional ...

Research Institutes In The Czech Republic
Research is "creative and systematic work undertaken to increase the stock of knowledge". It involves the collection, organization and analysis of evidence to increase understanding of a topic, characterized by a particular attentiveness to controlling sources of bias and error. These activities are characterized by accounting and controlling for biases. A research project may be an expansion on past work in the field. To test the validity of instruments, procedures, or experiments, research may replicate elements of prior projects or the project as a whole. The primary purposes of basic research (as opposed to applied research) are documentation, discovery, interpretation, and the research and development (R&D) of methods and systems for the advancement of human knowledge. Approaches to research depend on epistemologies, which vary considerably both within and between humanities and sciences. There are several forms of research: scientific, humanities, artistic, economi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Astronomical Observatories
This is a list of astronomical observatories ordered by name, along with initial dates of operation (where an accurate date is available) and location. The list also includes a final year of operation for many observatories that are no longer in operation. While other sciences, such as volcanology and meteorology, also use facilities called observatories for research and observations, this list is limited to observatories that are used to observe celestial objects. Astronomical observatories are mainly divided into four categories: space-based, airborne, ground-based, and underground-based. Many modern telescopes and observatories are located in space to observe astronomical objects in wavelengths of the electromagnetic spectrum that cannot penetrate the Earth's atmosphere (such as ultraviolet radiation, X-rays, and gamma rays) and are thus impossible to observe using ground-based telescopes. Being above the atmosphere, these space observatories can also avoid the effect ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Astronomical Institute Of Slovak Academy Of Sciences
The Astronomical Institute of Slovak Academy of Sciences was founded in 1953, when the state observatory on Skalnaté Pleso (founded in 1943 by Dr. Bečvář) got a status of astronomical institute and became one of the founding institutes of the newly born Slovakian Academy of Sciences. In memories of past and current employees, the institute and the observatory on Skalnaté Pleso were always blended in one and therefore one could consider for the year of the institute foundation already the 1943. Currently, it has its headquarters at Tatranská Lomnica. Field of research and organization of the institute The institute focuses its research on the Sun, interplanetary matter (comets, meteoroids, asteroids) and on astrophysical research of variable and chemically peculiar stars. It has about 65 permanent employees of which roughly 50 are active researchers. It is divided into 3 departments: Department of Solar Physics Interest in solar atmospheric activity led the department to ...

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. Duri ...

Clementinum
The Clementinum (''Klementinum'' in Czech) is a historic complex of buildings in Prague. Until recently the complex hosted the National, University and Technical libraries; the City Library was also nearby on Mariánské Náměstí. In 2009, the Technical library and the Municipal library moved to the Prague National Technical Library at Technická 6. It is in use as the National Library of the Czech Republic. In 2005, the Czech National Library received the UNESCO Jikji prize (Memory of the World). History Its history dates from the existence of a chapel dedicated to Saint Clement in the 11th century. A Dominican monastery was founded in the medieval period, which was transformed in 1556 to a Jesuit college. In 1622 the Jesuits transferred the library of Charles University to the Klementinum, and the college was merged with the University in 1654. The Jesuits remained until their suppression in 1773, when the Klementinum was established as an observatory, library, and unive ...
