LUCY
I'm doing a school project on the history of the television and i was wondering if anyone could give me any info like when it was first invented, when colour,3d and hd came in, how many channels it had at first, what they were made out of, when remote controls were invented and stuff like that? it's monday and my project is due wednesday so please help. thanks
Answer
I have to warn you, this is a very small paste from a huge article in Wikipedia.
I went to Google and wrote : advent of television invention and found many article and just selected a small section from Wikipedia.
paste:
The beginnings of mechanical television can be traced back to the discovery of the photoconductivity of the element selenium by Willoughby Smith in 1873, the invention of a scanning disk by Paul Gottlieb Nipkow in 1884 and John Logie Baird's demonstration of televised moving images in 1926.
As a 23-year-old German university student, Paul Nipkow proposed and patented the first electromechanical television system in 1884. Although he never built a working model of the system, variations of Nipkow's spinning-disk "image rasterizer" for television became exceedingly common, and remained in use until 1939. Constantin Perskyi had coined the word television in a paper read to the International Electricity Congress at the International World Fair in Paris on August 25, 1900. Perskyi's paper reviewed the existing electromechanical technologies, mentioning the work of Nipkow and others.
However, it was not until 1907 that developments in amplification tube technology, by Lee DeForest and Arthur Korn among others, made the design practical. The first demonstration of the instantaneous transmission of still silhouette images was by Georges Rignoux and A. Fournier in Paris in 1909, using a rotating mirror-drum as the scanner and a matrix of 64 selenium cells as the receiver.
In 1911, Boris Rosing and his student Vladimir Zworykin created a television system that used a mechanical mirror-drum scanner to transmit, in Zworykin's words, "very crude images" over wires to the "Braun tube" (cathode ray tube or "CRT") in the receiver. Moving images were not possible because, in the scanner, "the sensitivity was not enough and the selenium cell was very laggy".
On March 25, 1925, Scottish inventor John Logie Baird gave the first public demonstration of televised silhouette images in motion, at Selfridge's Department Store in London. AT&T's Bell Telephone Laboratories transmitted halftone still images of transparencies in May 1925. On June 13 of that year, Charles Francis Jenkins transmitted the silhouette image of a toy windmill in motion, over a distance of five miles from a naval radio station in Maryland to his laboratory in Washington, using a lensed disk scanner with a 48-line resolution.
However, if television is defined as the live transmission of moving images with continuous tonal variation, Baird first achieved this privately on October 2, 1925. But strictly speaking, Baird had not yet achieved moving images on October 2. His scanner worked at only five images per second, below the threshold required to give the illusion of motion, usually defined as at least 12 images per second. By January, he had improved the scan rate to 12.5 images per second.
Then on January 26, 1926 at his laboratory in London, Baird gave what is widely recognized as being the world's first demonstration of a working television system to members of the Royal Institution and a newspaper reporter.

But German stuff........hmmm
Oktoberfest
German beer - even though the first beer brewed was in Egypt, that is what Germany is most famous for.
Sauerkraut
Wienershnitzel
Wieners
Bratwurst
Liederhosen
3D Mars Camera
Airbag
Aspirin
Automobile
Bacteriology
Beer
C-Leg
Chipcard
Computer
Ecoflex Plastic
Glider
Gummi Bear **** My favorite!
Helicopter
Jet Engine
MP3 Format
Nuclear Fission
Nylon Plug
Radio-controlled watch
Record Player
Scanner
Small format camera
Social Legislation
Tape recorder
Television
The Pill
Theory of Relativity
Toothpaste
Twin Elevator
X-ray technology
I found all these at, http://germanoriginality.com/index.php , Americas German Originality.
I also found this one on inventors and their inventions
http://www.enchantedlearning.com/inventors/germany.shtml
Let's not forget some of the best music ever made came from German composers as well as some operas,
Handel, Bach, Bethoven, Hummel, Graun,Mendelssohn.
Pygmalian, Der Protagonist, Orpheus and Eurydike, Antigonae, Elektra.
Wagner (pronounced Vaugner) was one of the best composers of music and opers in the 19th century from Germany and is still praised today.
Glad to see you interested in yours and others heritage.
