The Inventors Behind the Creation of Television

Television wasnt invented by a single person. The efforts of many people working over the years, together and separately, contributed to the evolution of the technology. At the dawn of television history, two competing experimental approaches  led to the breakthroughs that eventually made the technology possible.  Early inventors attempted to build either a mechanical television based on Paul Nipkows rotating disks or an electronic television using a  cathode ray tube  developed independently in 1907 by English inventor A.A. Campbell-Swinton and Russian scientist Boris Rosing. Because electronic television systems worked better, they eventually replaced mechanical systems. Here is an overview of the major names and milestones behind one of the most important inventions of the 20th century. Mechanical Television Pioneers German inventor  Paul Gottlieb Nipkow developed a rotating disc technology in 1884 called the Nipkow disk to transmit pictures over wires. Nipkow is credited with  discovering televisions scanning principle, in which the light intensities of small portions of an image are successively analyzed and transmitted. In the 1920s, John Logie Baird patented the idea of using arrays of transparent rods to transmit images for television. Bairds 30-line images were the first demonstrations of television by reflected light rather than back-lit silhouettes.  Baird based his technology on Nipkows scanning disc idea and other developments in electronics. Charles Francis Jenkins invented a mechanical television system called Radiovision and claimed to have transmitted the earliest moving silhouette images on June 14, 1923. His company also  opened the first television broadcasting station in the U.S., named W3XK. Electronic Television Pioneers German scientist  Karl Ferdinand Braun entered history books by inventing the cathode ray tube (CRT) in 1897. This picture tube, which for years was the only device that could create the images viewers saw, was the basis for the advent of electronic television. In 1927, American Philo Taylor Farnsworth  became  the first inventor to transmit a television image—a dollar sign—comprising 60 horizontal lines. Farnsworth also developed the dissector tube, the basis of all current electronic televisions. Russian inventor  Vladimir Kosma Zworykin invented an improved cathode ray tube called the kinescope in 1929. Zworykin was one of the first to demonstrate a system with all the features that would come to make up televisions. Additional Television Components In 1947 Louis W. Parker invented the Intercarrier Sound System to synchronize television sound. His invention is used in all television receivers in the world. In June 1956  the TV remote controller first entered the American home. The first TV remote control, called Lazy Bones, was developed in 1950 by Zenith Electronics Corp., then known as Zenith Radio Corp. Marvin Middlemark invented rabbit ears, the once-ubiquitous V-shaped TV antennae, in 1953. His other inventions included a water-powered potato peeler and a rejuvenating tennis ball machine. Plasma TV display panels use small cells containing electrically charged ionized gases to generate high-quality imagery. The first prototype for a plasma display monitor was invented in 1964 by Donald Bitzer, Gene Slottow, and Robert Willson. Other Television Advances In 1925, Russian TV pioneer Zworykin filed a patent disclosure for an all-electronic color television system. Following authorization by the FCC, a color television system began commercial broadcasting on Dec. 17, 1953, based on a system invented by RCA. TV closed captions are hidden in the television video signal, invisible without a decoder. They were first demonstrated in 1972 and debuted the following year on the Public Broadcasting Service. Television content for the World Wide Web was rolled out in 1995. Historys first TV series made available on the Internet was  the public access program Rox.

Essay on Pigs Role in Animal Farm by George Orwell

Pigs Role in Animal Farm by George Orwell At the start of the novel Orwell describes the pigs to be the cleverest of the animals. This is clearly an advantage and so leads to the pigs taking over the farm. There is a sense of leadership very soon after Old Majors death as the three pigs, Snowball, Napoleon and Squealer arrange meetings with the other animals and already begin to give orders. You do not need sugar, says Snowball. It is evident here that Snowball believes that he has power over the other animals already. Further on during the second chapter Snowball and Napoleon send for a ladder, proving that they think they can use the animals to do jobs and progresses more in chapter 3 when they believe that they can†¦show more content†¦The only good human being is a dead one. This quote proves to us that Animalism is very important to Snowball. Orwell also describes Snowball to be quicker in speech. We can see that he is a brilliant speaker and uses this as a persuasive way to the control the animals instead of using force. Snowball also uses his intelligence to convince the birds that their wings are considered as legs. He says A birds wing, comrades, is an organ of propulsion and not of manipulation. It should therefore be regarded as a leg. Snowball is considered to be the most intelligent of the pigs. It is evident that this is true when he plans to build a windmill to supply electricty on the farm. He was closeted there for hours at a time. This quote shows again Snowballs strong passion for the farm as he spends hours working on plans for innovations and improvements. Napoleon cannot accept that Snowball is the cleverest out of them both and this is proved to us again when Snowball makes Animal Comittees to teach the animals to read and write as Napoleon claimis that the education of the young is far more important than that of the older animals. He says this clearly because he is jealous of Snowball and wants power and glory all the time. Orwell describes Napoleon as large and fierce-looking. From this description we picture him to be extremely intimidating and he uses this throughout the novel to control the other animals. It is obvious that NapoleonShow MoreRelatedAnimal Farm, By George Orwell1243 Words   |  5 Pagesâ€Å"All animals are equal but some animals are more equal than others.† In George Orwell’s novel, Animal Farm, farm animals drive out their farmer and live in an environment where all animals are equal.
