Telstar (play)
Telstar is the name of various communications satellites. The first two Telstar satellites were experimental and nearly identical. Telstar 1 launched on top of a Thor-Delta rocket on July 10, 1962. It successfully relayed through space the first television pictures, telephone calls, and telegraph images, and provided the first live transatlantic television feed. Telstar 2 launched May 7, 1963. Telstar 1 and 2—though no longer functional—still orbit the Earth. Description Belonging to AT&T, the original Telstar was part of a multi-national agreement among AT&T (USA), Bell Telephone Laboratories (USA), NASA (USA), GPO (United Kingdom) and the National PTT (France) to develop experimental satellite communications over the Atlantic Ocean. Bell Labs held a contract with NASA, paying the agency for each launch, independent of success. Six ground stations were built to communicate with Telstar, one each in the US, France, the UK, Canada, West Germany and Italy. The Americ ...

Fucino
The Fucine Lake ( it, Lago Fucino or ) was a large endorheic lake in western Abruzzo, central Italy, stretching from Avezzano in the northwest to Ortucchio in the southeast, and touching Trasacco in the southwest. Once the third largest lake in Italy, it was drained in 1878. Lore Virgil mentioned the former lake in the Aeneid in book 7, in that it weeps for Umbro, the healer priest killed tragically in battle. (See line 7:882 in the Fagles translation). Roman drainage The Romans knew the lake as ''Fucinus Lacus'' and founded settlements on its banks, including Marruvium. It was the site of the Battle of Fucine Lake in 89 BC; however, while the lake provided fertile soil and a large quantity of fish, it was also believed to harbour malaria, and, having no natural outflow, repeatedly flooded the surrounding arable land. The Emperor Claudius attempted to control the lake's maximum level by digging a drainage tunnel through ''Monte Salviano'', requiring 30,000 workers and eleve ...

Bavaria
Bavaria ( ; ), officially the Free State of Bavaria (german: Freistaat Bayern, link=no ), is a state in the south-east of Germany. With an area of , Bavaria is the largest German state by land area, comprising roughly a fifth of the total land area of Germany. With over 13 million inhabitants, it is second in population only to North Rhine-Westphalia, but due to its large size its population density is below the German average. Bavaria's main cities are Munich (its capital and largest city and also the third largest city in Germany), Nuremberg, and Augsburg.

405-line Television System
The 405-line monochrome analogue television broadcasting system was the first fully electronic television system to be used in regular broadcasting. The number of television lines influences the image resolution, or quality of the picture. It was introduced with the BBC Television Service in 1936, suspended for the duration of World War II, and remained in operation in the UK until 1985. It was also used between 1961 and 1982 in Ireland, as well as from 1957 to 1973 for the Rediffusion Television cable service in Hong Kong. Sometimes called the Marconi-EMI system, it was developed in 1934 by the EMI Research Team led by Isaac Shoenberg. The figure of 405 lines had been chosen following discussions over Sunday lunch at the home of Alan Blumlein. The system used interlacing; EMI had been experimenting with a 243-line all-electronic interlaced system since 1933. In the 405 system the scanning lines were broadcast in two complementary fields, 50 times per second, creating 25 frame ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
