Television



Before the end of the nineteenth century, the watched media crept to take the lead position in the public imagination. Originally, the camera, which showed enormous capacity to produce images identical to nature, and for a moment in transit, in an automated fashion. It seemed like a culmination of a huge humanitarian effort and an uphold of the eye among other senses. What can be seen becomes plausible amazingly, despite the common knowledge can deceive the senses. In 1898, the Lumiere brothers launched the cinema with its fantasy and images. In the same year, Marie Curie put her hand between the tube of radium, which showed the image of the hand bones and the wedding ring. That was the first X-ray image, and that was the beginning of the image era in science. These discoveries branded the twentieth century with a distinctive visual character, so it became an era dominated by the image, especially with spread of the cinema.



The image reached its peak with the visual dominance of television and its spread, and so it was the tool of choice for art, in addition to the wealth the image got with values and connotations. Ironically, one of the early innovators of television broadcast technology, the American Philo Farnsworth, was famous for his vigilance from the seriousness of this tool. Farnsworth was born on 19 July 1906, in the U.S. state of Utah. He showed remarkable superiority in the science of theoretical physics and amazed his teachers when he was capable of explaining Einstein's relativity theory at an early age. Busy, in his youth, to find practical applications for the electric - light effect that Einstein discovered and received the Nobel Prize in Physics for.


In the details of this discovery, which is the basis of television and later the computer, Einstein alerted to the fact that the passage of bundles of light of a particular kind (In other words, a steady stream of electrons), in a tense circuit, leads to the generation of specific patterns, and certain forms of electromagnetic waves; which means that electromagnetic waves can be transformed to lines and drawings. Little Farnsworth picked up this thread and worked diligently to develop the idea of inspired revelation of the field and parallel lines.



Before he was fourteen years old, he thought of the possibility of cutting the picture into a group of small parallel lines, as the plow does when it cuts the field into lines and even more he had a perception that it is possible to reproduce such lines on the electronic form of electromagnetic waves to be broadcasted according to Einstein's theory for the optical - electromagnetic effect. Thus, he had to invent 3 things: a device that converts camera images to small electronic lines, an instrument which converts those lines into specific electromagnetic waves, and finally a device that responds to electromagnetic waves and then converts them into small electronic lines to match the images they were originally generated from.


During his scientific career, Farnsworth was able to make two of those three things. In 1927, he invented a device for cutting the images into small straight lines, and called it Image Dissector. Two years later, he made a device for the reintegration of those lines and called it Fauser, which effectively allowed the manufacture of electronic television. John Logie Baird made the third device, which is the device converting the electronic chopped lines into electromagnetic waves to be easily broadcasted, in addition to manufacturing cathode tube, which allows transfer of images collected by the device Fauser into scenes seen on the silver screen.


In 1921, Farnsworth was able to elaborate the basic idea for making electronic images and broadcast them. In 1927, he applied his idea about cutting the image, and by an experiment that entered the history of technology. He Drew a straight line at the center of a square made of glass painted black. Then put this box between a particular imaging device, that can cut the images into small electronic lines.


It was considered to be the experience of the first televised broadcast. For further illumination of this invention, it is sufficient to note that the voice is broadcasted through the electromagnetic waves which are radio waves, as demonstrated by the Italian innovator Marconi.


Thus, electromagnetic waves became common carrier of voice and image. Farnsworth did not work on the sound, nor on the integration of sound and image, and not on making devices which receive electromagnetic waves that carry sound and picture together. Those things were done by other innovators, such as the Scottish John Logie Baird.


At the same time, it is remarkable to notice that Farnsworth was the one who created the tool cutting the images into electronic lines, as well as converting those lines to the electromagnetic waves, like radio waves. According to this, Farnsworth is the innovator who paved the way to manufacture the electronic television.


In 1939, he won a patent dedicated for his contribution in the creation of television. Farnsworth only left behind a single television interview, during which he reiterated criticism of the dominance of television on daily life. He described it as: « very painful». Later, His wife, who died in 2004, talked again about the pain of the Television that Farnsworth helped in its creation and spread. The device that he described as a «kind of monster, disguised as a tool to entertain people». She also quoted him as saying he feared that television weakens the mental capacity for his son. In 1971, Farnsworth died, after he almost became forgotten.




Television...a device that changed the way we live..
