Kościan
Kościan (german: Kosten) is a town on the Obra canal in west-central Poland, with a population of 23 952 inhabitants as of June 2014. Situated in the Greater Poland Voivodeship (since 1999), previously in Leszno Voivodeship (1975–1998), it is the capital of Kościan County. Polish nobleman Ignacy Wyssogota Zakrzewski was born nearby. History Kościan was founded in the 12th or 13th century, when it was part of the Duchy of Greater Poland of the fragmented Polish realm.Leon Plater, ''Opisanie historyczno-statystyczne Wielkiego Księztwa Poznańskiego'', Księgarnia Zagraniczna, Lipsk, 1846, p. 207 (in Polish) It was granted town rights in the second half of the 13th century, which were later confirmed by King Władysław Jagiełło in 1400.

In the 15th century Kościan was famous for its cloth production. King Casimir ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electromagnetic
In physics, electromagnetism is an interaction that occurs between particles with electric charge. It is the second-strongest of the four fundamental interactions, after the strong force, and it is the dominant force in the interactions of atoms and molecules. Electromagnetism can be thought of as a combination of electrostatics, electricity and magnetism, two distinct but closely intertwined phenomena. In essence, electric forces occur between any two charged particles, causing an attraction between particles with opposite charges and repulsion between particles with the same charge, while magnetism is an interaction that occurs exclusively between ''moving'' charged particles. These two effects combine to create electromagnetic fields in the vicinity of charge particles, which can exert influence on other particles via the Lorentz force. At high energy, the weak force and electromagnetic force are unified as a single electroweak interaction, electroweak force. The electroma ...

Sound Recording
Sound recording and reproduction is the electrical, mechanical, electronic, or digital inscription and re-creation of sound waves, such as spoken voice, singing, instrumental music, or sound effects. The two main classes of sound recording technology are analog recording and digital recording. Sound recording is the transcription of invisible vibrations in air onto a storage medium such as a phonograph disc. The process is reversed in sound reproduction, and the variations stored on the medium are transformed back into sound waves. Acoustic analog recording is achieved by a microphone diaphragm that senses changes in atmospheric pressure caused by acoustic sound waves and records them as a mechanical representation of the sound waves on a medium such as a phonograph record (in which a stylus cuts grooves on a record). In magnetic tape recording, the sound waves vibrate the microphone diaphragm and are converted into a varying electric current, which is then converted to a ...

Oldenburg (city)
Oldenburg () is an independent city in the state of Lower Saxony, Germany. The city is officially named Oldenburg (Oldb) (''Oldenburg in Oldenburg'') to distinguish from Oldenburg in Holstein. During the French annexation (1811–1813) in the wake of the Napoleonic war against Britain, it was also known as ''Le Vieux-Bourg'' in French. The city is at the rivers Hunte and Haaren, in the northwestern region between the cities of Bremen in the east and Groningen (Netherlands) in the west. It has a population of 170,000 (November 2019). Oldenburg is part of the Bremen/Oldenburg Metropolitan Region, with 2.37 million people. The city is the place of origin of the House of Oldenburg. Before the end of the German Empire (1918), it was the administrative centre and residence of the monarchs of Oldenburg.

Siemens & Halske AG
Siemens & Halske AG (or Siemens-Halske) was a German electrical engineering company that later became part of Siemens. It was founded on 12 October 1847 as ''Telegraphen-Bauanstalt von Siemens & Halske'' by Werner von Siemens and Johann Georg Halske. The company, located in Berlin-Kreuzberg, specialised in manufacturing electrical telegraphs according to Charles Wheatstone's patent of 1837. In 1848, the company constructed one of the first European telegraph lines from Berlin to Frankfurt am Main. Siemens & Halske was not alone in the realm of electrical engineering. In 1887, Emil Rathenau had established ''Allgemeine Elektrizitäts-Gesellschaft'' (AEG), which became a long-time rival. In 1881, Siemens & Halske built the Gross-Lichterfelde Tramway, the world's first electric streetcar line, in the southwestern Lichterfelde suburb of Berlin, followed by the Mödling and Hinterbrühl Tram near Vienna, the first electrical interurban tram in Austria-Hungary. 1882 saw the openi ...

Reichs-Rundfunk-Gesellschaft
The Reichs-Rundfunk-Gesellschaft (RRG; ''Reich Broadcasting Corporation'') was a national network of German regional public radio and television broadcasting companies active from 1925 until 1945. RRG's broadcasts were receivable in all parts of Germany and were used extensively for Nazi propaganda after 1933. Historical recordings of RRG broadcasts are today held by the German Broadcasting Archive. History The company was established in Berlin on 15 May 1925 with a start capital of 100,000 Reichsmark as an umbrella organisation by nine regional broadcasters – that is to say, all of the German radio stations other than the Deutsche Stunde in Bayern – serving the various states of the Weimar Republic. From 1926, a majority share was held by the state-owned Deutsche Reichspost authority, represented by RF engineer and Reichspostministerium official Hans Bredow as chairman in the rank of a ''Reichs-Rundfunk-Kommissar''. The logo of the RRG was designed by German graphic de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ufa-Palast Am Zoo
The Ufa-Palast am Zoo, located near Berlin Zoological Garden in the New West area of Charlottenburg, was a major Berlin cinema owned by Universum Film AG, or Ufa. Opened in 1919 and enlarged in 1925, it was the largest cinema in Germany until 1929 and was one of the main locations of film premières in the country. The building was destroyed in November 1943 during the Bombing of Berlin in World War II and replaced in 1957 by the Zoo Palast. History The Neo-Romanesque building at Hardenbergstraße was designed as an exhibition hall by architect Carl Gause (1851–1907), an alumnus of the Bauakademie who had also drawn plans for the Hotel Adlon. Like the '' Romanisches Haus'' nearby, the design followed the model of the Kaiser Wilhelm Memorial Church at Auguste-Viktoria-Platz (present-day Breitscheidplatz), built in 1891–1895 according to plans by Franz Schwechten. The development of a "Romanesque forum" met the demands of Emperor Wilhelm II who even set guidelines for the de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

People From Gelsenkirchen
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of per ...
