František Nušl
František Nušl (; 3 December 1867, in Jindřichův Hradec – 17 September 1951, in Prague) was a Czech astronomer and mathematician. Life After high school in Jindřichův Hradec, he studied physics and astronomy in Prague, where he met among others the future president of Czechoslovakia, T. G. Masaryk, the linguist Jan Gebauer and the historian Josef Goll, with whom he collaborated on Otto's encyclopedia. After 1893 he taught maths on various high schools and met with J. J. Frič, a manufacturer of precision instruments. In 1898 Frič bought a large piece of land in Ondřejov, 50 km south-east from Prague, where they established an astronomical observatory. Since 1904 Nušl was assistant professor of astronomy at the Charles University of Prague and after 1908 professor of mathematics at the Czech Technical University in Prague (ČVUT). In 1917, Nušl was among the founders of the Czech Astronomical Society, whose president he was to become later. In 1928 Frič dedic ...

Petřín
Petřín () is a hill in the centre of Prague, Czech Republic. It rises 327 m above sea level and some 130 m above the left bank of the Vltava River. The hill, almost entirely covered with parks, is a favorite recreational area for the inhabitants of Prague. The hill (in German known as ''Laurenziberg'') is featured prominently in Franz Kafka's early short story "Description of a Struggle" and briefly in Milan Kundera's novel ''The Unbearable Lightness of Being''. The chronicler Cosmas describes Petřín as a very rocky place, the hill is allegedly called Petřín because of the large number of rocks (Latin: petra). Since ancient times, stones were dug and were used to construct buildings in Prague. Medieval defence wall, the Hunger Wall was built on Petřín Hill during 1360 - 1362, by the order of king of Bohemia Charles IV. The Petřín Lookout Tower, which strongly resembles the Eiffel Tower, was built atop a hill in 1891. Other sights include the Rose Garden, Mirror Maze, ...

Charles University Alumni
Charles is a masculine given name predominantly found in English and French speaking countries. It is from the French form ''Charles'' of the Proto-Germanic name (in runic alphabet) or ''*karilaz'' (in Latin alphabet), whose meaning was "free man". The Old English descendant of this word was '' Ċearl'' or ''Ċeorl'', as the name of King Cearl of Mercia, that disappeared after the Norman conquest of England. The name was notably borne by Charlemagne (Charles the Great), and was at the time Latinized as ''Karolus'' (as in ''Vita Karoli Magni''), later also as '' Carolus''. Some Germanic languages, for example Dutch and German, have retained the word in two separate senses. In the particular case of Dutch, ''Karel'' refers to the given name, whereas the noun ''kerel'' means "a bloke, fellow, man". Etymology The name's etymology is a Common Germanic noun ''*karilaz'' meaning "free man", which survives in English as churl (< Old English ''ċeorl''), which developed its depr ...

Masaryk University
Masaryk University (MU) ( cs, Masarykova univerzita; la, Universitas Masarykiana Brunensis) is the second largest university in the Czech Republic, a member of the Compostela Group and the Utrecht Network. Founded in 1919 in Brno as the second Czech university (after Charles University established in 1348 and Palacký University existent in 1573–1860), it now consists of ten faculties and 35,115 students. It is named after Tomáš Garrigue Masaryk, the first president of an independent Czechoslovakia as well as the leader of the movement for a second Czech university. In 1960 the university was renamed ''Jan Evangelista Purkyně University'' after Jan Evangelista Purkyně, a Czech biologist. In 1990, following the Velvet Revolution it regained its original name. Since 1922, over 171,000 students have graduated from the university. History Masaryk University was founded on 28 January 1919 with four faculties: Law, Medicine, Science, and Arts.

Moon
The Moon is Earth's only natural satellite. It is the fifth largest satellite in the Solar System and the largest and most massive relative to its parent planet, with a diameter about one-quarter that of Earth (comparable to the width of Australia). The Moon is a planetary-mass object with a differentiated rocky body, making it a satellite planet under the geophysical definitions of the term and larger than all known dwarf planets of the Solar System. It lacks any significant atmosphere, hydrosphere, or magnetic field. Its surface gravity is about one-sixth of Earth's at , with Jupiter's moon Io being the only satellite in the Solar System known to have a higher surface gravity and density. The Moon orbits Earth at an average distance of , or about 30 times Earth's diameter. Its gravitational influence is the main driver of Earth's tides and very slowly lengthens Earth's day. The Moon's orbit around Earth has a sidereal period of 27.3 days. During each synodic period ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Asteroid
An asteroid is a minor planet of the inner Solar System. Sizes and shapes of asteroids vary significantly, ranging from 1-meter rocks to a dwarf planet almost 1000 km in diameter; they are rocky, metallic or icy bodies with no atmosphere. Of the roughly one million known asteroids the greatest number are located between the orbits of Mars and Jupiter, approximately 2 to 4 AU from the Sun, in the main asteroid belt. Asteroids are generally classified to be of three types: C-type, M-type, and S-type. These were named after and are generally identified with carbonaceous, metallic, and silicaceous compositions, respectively. The size of asteroids varies greatly; the largest, Ceres, is almost across and qualifies as a dwarf planet. The total mass of all the asteroids combined is only 3% that of Earth's Moon. The majority of main belt asteroids follow slightly elliptical, stable orbits, revolving in the same direction as the Earth and taking from three to six years to comple ...

Mercury occurs in deposits throughout the world mostly as cinnabar (mercuric sulfide). The red pigment vermilion is obtained by Mill (grinding), grinding natural cinnabar or synthetic mercuric sulfide. Mercury is used in ...
