Gorce Mountains
The Gorce Mountains ( pl, Gorce ) are part of the Western Beskids mountain range spreading across southernmost Poland. They are situated in Małopolska Province, at the western tip of the long Carpathian range extending east beyond the Dunajec River for some . The Gorce are characterized by numerous ridges reaching in all directions for up to with a series of higher elevations cut by deep river valleys. The range is dominated by about a dozen gentle peaks including Turbacz (the highest, at above sea level) in the centre, and – facing east: Jaworzyna Kamienicka (), Kiczora (), Kudłoń (), Przysłop, Czoło and Gorc Kamienicki. The south-eastern ridge of the Gorce reaches the Pieniny range (cut off by the Ochotnica pass), with Lubań () as its tallest peak followed by Pasterski Wierch, Runek and Marszałek. The north-west ridges include Obidowiec, and the peak of Suhora (1,000 m (3,300 ft)) featuring an astronomical observatory owned and operated by the Pedagogical ...

Cassegrain Reflector
The Cassegrain reflector is a combination of a primary concave mirror and a secondary convex mirror, often used in optical telescopes and radio antennas, the main characteristic being that the optical path folds back onto itself, relative to the optical system's primary mirror entrance aperture. This design puts the focal point at a convenient location behind the primary mirror and the convex secondary adds a telephoto effect creating a much longer focal length in a mechanically short system. In a symmetrical Cassegrain both mirrors are aligned about the optical axis, and the primary mirror usually contains a hole in the center, thus permitting the light to reach an eyepiece, a camera, or an image sensor. Alternatively, as in many radio telescopes, the final focus may be in front of the primary. In an asymmetrical Cassegrain, the mirror(s) may be tilted to avoid obscuration of the primary or to avoid the need for a hole in the primary mirror (or both). The classic Cassegrain ...

Astronomy
Astronomy () is a natural science that studies astronomical object, celestial objects and phenomena. It uses mathematics, physics, and chemistry in order to explain their origin and chronology of the Universe, evolution. Objects of interest include planets, natural satellite, moons, stars, nebulae, galaxy, 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 atmosphere of Earth, 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 Babylonian astronomy, Babylonians, Greek astronomy, Greeks, Indian astronomy, Indians, Egyptian astronomy, Egyptians, Chinese astronomy, Chinese, Maya civilization, Maya, and many anc ...

Observatory
An observatory is a location used for observing terrestrial, marine, or celestial events. Astronomy, climatology/meteorology, geophysical, oceanography and volcanology are examples of disciplines for which observatories have been constructed. Historically, observatories were as simple as containing an astronomical sextant (for measuring the distance between stars) or Stonehenge (which has some alignments on astronomical phenomena). Astronomical observatories Astronomical observatories are mainly divided into four categories: space-based, airborne, ground-based, and underground-based. Ground-based observatories Ground-based observatories, located on the surface of Earth, are used to make observations in the radio and visible light portions of the electromagnetic spectrum. Most optical telescopes are housed within a dome or similar structure, to protect the delicate instruments from the elements. Telescope domes have a slit or other opening in the roof that can be opened during ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pedagogical University Of Cracow
The Pedagogical University of Cracow ( pl, Uniwersytet Pedagogiczny im. Komisji Edukacji Narodowej w Krakowie, UP), is named after the Commission of National Education created by King Stanisław August Poniatowski. It is a public university located in Kraków, Poland. It was founded soon after the conclusion of World War II, on May 11, 1946, originally as the National Higher College of Teacher Training. Its aim is the training of highly qualified teaching staff for the Polish educational system. The Pedagogical University is the earliest pedagogical university in postwar Poland. It functions according to the model of integrated education combining theoretical knowledge with practical skills. The mission of the university is reinforced in scientific research and development according to the highest European standards in several dozen fields of studies. It runs first-cycle (bachelor's) and second-cycle (master's) degree programmes, as well as in the third-cycle degree studies (Ph.D.) ...

Gorce National Park
Gorce National Park ( pl, Gorczański Park Narodowy) is a national park in Lesser Poland Voivodeship, southern Poland. It covers central and northeastern parts of the Gorce Mountains, which are part of the Western Beskids (at the western end of the Carpathian range). The first steps to protect this land go back to 1927, when a forest reserve was set up on land owned by Count Ludwik Wodzicki of Poręba Wielka. The National Park was created in 1981, then covering 23.9 square kilometres. Today, the area of the park has grown to , of which 65.91 km2 is forested. The area of the protective zone around the park is 166.47 km2. The park lies within Limanowa County and Nowy Targ County, and has its headquarters in Poręba Wielka. The Gorce range is dominated by arched peaks and river valleys which cut into the range. There are a few small caves and obviously - several peaks such as Turbacz (the highest - 1310 meters above sea level), Jaworzyna Kamienicka, Kiczora, Kudłoń ...

Kraków
Kraków (), or Cracow, is the second-largest and one of the oldest cities in Poland. Situated on the Vistula River in Lesser Poland Voivodeship, the city dates back to the seventh century. Kraków was the official capital of Poland until 1596 and has traditionally been one of the leading centres of Polish academic, economic, cultural and artistic life. Cited as one of Europe's most beautiful cities, its Old Town with Wawel Royal Castle was declared a UNESCO World Heritage Site in 1978, one of the first 12 sites granted the status. The city has grown from a Stone Age settlement to Poland's second-most-important city. It began as a hamlet on Wawel Hill and was reported by Ibrahim Ibn Yakoub, a merchant from Cordoba, as a busy trading centre of Central Europe in 985. With the establishment of new universities and cultural venues at the emergence of the Second Polish Republic in 1918 and throughout the 20th century, Kraków reaffirmed its role as a major national academic and a ...

Photometer
A photometer is an instrument that measures the strength of electromagnetic radiation in the range from ultraviolet to infrared and including the visible spectrum. Most photometers convert light into an electric current using a photoresistor, photodiode, or photomultiplier. Photometers measure: *Illuminance *Irradiance *Light absorption * Scattering of light *Reflection of light *Fluorescence *Phosphorescence *Luminescence History Before electronic light sensitive elements were developed, photometry was done by estimation by the eye. The relative luminous flux of a source was compared with a standard source. The photometer is placed such that the illuminance from the source being investigated is equal to the standard source, as the human eye can judge equal illuminance. The relative luminous fluxes can then be calculated as the illuminance decreases proportionally to the inverse square of distance. A standard example of such a photometer consists of a piece of paper with an o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charge-coupled Device
A charge-coupled device (CCD) is an integrated circuit containing an array of linked, or coupled, capacitors. Under the control of an external circuit, each capacitor can transfer its electric charge to a neighboring capacitor. CCD sensors are a major technology used in digital imaging. In a CCD image sensor, pixels are represented by p-doped metal–oxide–semiconductor (MOS) capacitors. These MOS capacitors, the basic building blocks of a CCD, are biased above the threshold for inversion when image acquisition begins, allowing the conversion of incoming photons into electron charges at the semiconductor-oxide interface; the CCD is then used to read out these charges. Although CCDs are not the only technology to allow for light detection, CCD image sensors are widely used in professional, medical, and scientific applications where high-quality image data are required. In applications with less exacting quality demands, such as consumer and professional digital cameras, act ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
