THOMAS ALVA EDISON

Versatile inventor Thomas Alva Edison was born in 1847 in Milan, Ohio, United States. Just three years he received formal education, after it kicked out of school because the teacher thought the child was incredible stupid.                                                                                                                                      His first creation, electronic voice recorder dibikinnya when he was twenty one years. Her work did not sell. After that he earned expectation fabrication equipment can be sold in the market, shortly after he managed to make an electronic voice recorder, he discovered and perfected telegraph machines that automatically print the letter, which sold for 40,000 dollars, a huge amount at that time. After that, as he queued to find new work and in a short time Edison was not only famous but also the rich. Perhaps, the most original invention is a patented machine LPs in 1877. However, more famous in the world than it is the development of a practical incandescent light bulb in 1879.                                                                      Edison was not the first to create a system of electric lighting. A few years earlier bersinarkan light electric current has been used for street lighting in Paris. However, the ball follows Edison incandescent electric power distribution system which enables the development of practical electric lighting for the home. In 1882, his company began producing electricity for homes in New York, and in a short time had spread throughout the world.                                                                                               With the establishment of the first electricity for lighting homes, Edison is already laying the groundwork for the development of big industry. The use of electric power is not just for lighting but for all aspects of their household needs, ranging from televisions to washing machines. Furthermore, the use of electricity through the distribution networks established Edison in itself encourage the use of electricity for the industrial sector.                                                                                                                            Edison also gave large donations made remarkable progress film cameras and projectors. He made important improvements pertilponan (carbon transmitter increase the clarity of hearing), improvements in the field telegraph, and typewriter. Among other findings, among others, dictation machines, coffee machines and battery-driven storage. Arguably, Edison designed more than 1000 inventions, a number that really does not make sense.                                                                                 One reason for its productivity is very surprising because in the beginning of his career he built a laboratory investigation in Menlo Park, New Jersey. That's where he called for the group which enabled makers to help him. This is the embryo of a laboratory investigation that later imitated by so many industries. Edison beginner modern laboratories, a fully equipped central inquiry where so many people working together is a team, is also the result of his work is important, though, of course, something she could not patented.                                                                                                                               Edison was not only an inventor, he also engaged in fabrication and organizing various industrial companies. The most important of which eventually transformed into the General Electric Company.                 Although the traits he's not a pure scientist, Edison make a scientific discovery. In 1882 he found that in a state of near vacuum, electric current can flow between the two wires are not touching each other. This phenomenon-called Edison's invention has a purpose-not just theoretical importance, but also have practical use meaningful sense. This leads to the development of vacuum tubes and laying the basis of the electronics industry.                                                                                                                                                Almost all his lifetime, Edison suffered from weak hearing. But, even so, he is more than able to overcome it with hard work are amazing. Edison married twice (his first wife died young), has three children from each wife. He died in 1931 in West Orange, New Jersey.                                                                     There was no disagreement about the talent Edison. Everyone agreed that he was the inventor of the genius who ever lived. Rows of his findings are very helpful considered appalling and raise a knee chills, although perhaps only partly developed by another person within thirty years. However, if we consider his personal discoveries, would seem to us that none of it has a decisive significance. For example, incandescent ball, although widely used, is not an irreplaceable items in the modern world. The fact is, lighting that comes from the radiation and the outgoing scattered in the form of light, which works on the basis of scientific principles are entirely different, also used by people at large, and in our daily lives does not make any difference if we do not use incandescent light bulbs altogether. Indeed, prior to use electric lighting, candles, oil lamps, and gas lamps are generally regarded as satisfactory levels of illumination.                                                                                                                                    LPs tool is a clever invention, but nobody thought the device was able to change our daily lives as well as the role that served the radio, television or telephone. Furthermore, in recent years, has to be created a voice recording device with an entirely different method, such as magnetic tape cassettes. And if there is no machine record, it did not feel anything. Many of Edison's patents relating to the improvement of tools, have actually been found by other people first, even in a form that can be utilized. These improvements, although many help-can not be considered as an important meaning in the series of historical movements in general.                                                                                     But, although none of Edison's inventions have an appalling significance, useful also to remember that he did not just create a single tool, but more than a thousand. On the basis of these considerations I put Edison higher than such famous inventor Guglielmo Marconi and Alexander Graham Bell.
