Versatile inventor Thomas Alva Edison was born in 1847 in Milan, Ohio, USA. 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 fabrication equipment that can diharapnya sold in the market, shortly after he managed to make an electronic voice recorder, he discovered and perfected engine telegraph which automatically prints 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 inventions are patented machine that records 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. Several years before the electric current bersinarkan lights have been used for lighting street lamps in Paris. However, following Edison's incandescent bulb electric power distribution system which enables the development of practical electric lighting for the home. 1882, the 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 electric lighting for 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 household needs, ranging from televisions to washing machines. Furthermore, the use of electricity through the distribution networks that Edison established itself encourages the use of electricity for industrial sectors.
Edison also contributed for the development of the extraordinary film cameras and projectors. He made important improvements pertilponan (carbon transmiternya improve the clarity of hearing), improvements in the telegraph, and typewriter. Among other findings, among others, dictation machines, coffee machines and the storage battery-driven. Arguably, designing more than 1000 Edison invention, an amount that is really absurd.
One very surprising because their productivity is due at the beginning of his career he built a laboratory investigation in Menlo Park, New Jersey. That's where he gathered a 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 that he could not patented.
Edison was not only an inventor, he also was involved in organizing various construction and 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 discovered that in a state of near vacuum, electrical current can flow between the two wires are not touching each other. This phenomenon - called Edison's invention - not just have important theoretical intention, but also mean a significant practical use. This leads to the development of vacuum tubes and the foundation 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 is 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 great genius inventor who ever lived. Rows of his findings are very useful and make considered shocking knee chills, although it may be partially developed by other people 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 bulb, although widely used, is not an irreplaceable items in the modern world. The fact is, illumination from scattered radiation and outgoing in the form of light, which works on the basis of scientific principles are entirely different, is also widely used by people, 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 tool was able to transform our everyday lives as well as the role presented a radio, television or telephone. Furthermore, in recent years, has created a tool can be a voice recorder with an entirely different method, such as magnetic tape cassette. And if there is no machine record, it does nothing. Many of Edison's patents relating to the improvement of tools, have actually been discovered by others first, even in a form that can be utilized. Improvements in this - although a lot of help - can not be regarded as an important meaning in the sequence of history in general.
But, although none of the inventions Edison-shattering importance, is also useful 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.

Inilah Johann Gutenberg printing press inventor figures 1400-1468

Commonly considered the inventor Johann Gutenberg printing press. What he actually did was to develop the first method involved the use of print and the printing press in the form such a way that the various kinds of written material can be printed quickly and accurately.
There was no finding that jumped out of one's thoughts, not even the printing press. Seals and seal spheres adhere to the principle that the process is similar to block printing was known in China for centuries before Gutenberg was born and the evidence shows that in the year 868 AD a printed book was discovered in China. A similar process has been known in Europe before Gutenberg. Print block allows printing many copies of certain books. This process has one big disadvantage: because a new and complete set of woodcut or metal must be made to a book, by itself it is not practical to print a wide variety of books.
Often called the most important contributions was the discovery in the field of Gutenberg printing letters that can move. In this case too similar things have been discovered in China around the middle of the 11th century AD by a man named Pi Sheng. The letters original print made from a kind of land that can not be durable. Meanwhile, some Chinese and Koreans have done a series of improvements and work well before Gutenberg. The Koreans use metal printing letters, and the Korean government helped a smelter to produce printed letters at the beginning of the 15th century AD Apart from all this, is also wrong to assume Pi Sheng had a special influence. At the first level, Europeans do not learn to print letters move from China but on his own creations. Second, the printing by way of printed letters move has never been used in general in China's own until just recently when modern printing procedures they learned from the West.
There are four essential components of modern way of printing. First, print letters that move, following some adjustment procedures and placement of letters established. Second, the printing press itself. Third, matching ink to produce prints. Fourth, the materials such as paper to print them. Paper has been found in China years before the printing press by Ts'ai Lun and its use was widespread in Europe before the days of Gutenberg. That is the only element of the Gutenberg printing process that is ready to be. Although others have done all kinds of work on each component, but Gutenberg has successfully assorted improvements. For example, he developed a metal alloy for printing letters poured molten metal to block print letters correctly and accurately; oil printing ink and pressure equipment needed to print.
However, the overall contribution of Gutenberg mind is bigger than anyone else in terms of perfecting the printing press. Its importance lies in its success mainly combines all the elements of the printing press to be an effective and productive system. Therefore, printing machines, in contrast with other previous findings, a large-scale production process are key. Sepucuk rifle itself is far more effective than a bow and arrow. A printed book is not much different from the results of a handwritten book. Excess printing machine thus lies in its massive production terms. What has been developed by Gutenberg was not the invention of a device or reason, and not just a series of improvements, but a complete production process.
Biographical Treasury Gutenberg us about yourself so rare, we only know he was born in Germany around 1400 AD in the city of Mainz. His contributions to the art prints in the mid-century prints and terbagusnya job - what is called the Gutenberg Bible - printed in Mainz around the year 1454 AD Oddly, the name of Gutenberg was never listed in any book, nor in the Gutenberg Bible, although he himself clearly printed by means of discovery.
Gutenberg did not ever appear as a businessman, he really had no desire to money from his invention. He was frequently involved with court charges resulting in the need for him to pay ransom in the form of equipment furnished to his friend named Johann Fust. Gutenberg died in 1468 in the town of Mainz.
One of the Gutenberg influence in world history can be profitable if we associate with the development in China and Europe in the next period. At the time of Gutenberg was born, the two regions was almost as advanced. But after Gutenberg invented printing European darted forward with the speed, while China - which still uses the block print - its development is rather slow. Maybe too much if we say the development of printing the only factors that cause different degrees of progress, but the findings clearly have important meaning that can not be removed.
Also worth noting if only three people in this book list live in the five centuries before Gutenberg, while sixty-seven live in the five centuries after Gutenberg's death. This shows how the invention Gutenberg very meaningful - even can be called an important discovery - in relation to the progress of the revolution trigger the withdrawal of the modern era.
Alexander Graham Bell may not even born into the world but the phone remains found at the same time in history. So also could take a sample of other inventions, without Gutenberg, the invention of modern printing will be delayed a few generations, and measured its effects from the great, unmistakable Gutenberg to honor the order listed in this book.
