Mother knows that Al liked chemistry and electronics, so he frequently bought books of Al with respect to the field. One of the books owned by Al explains how the practice of chemistry experiments at home, from the book that Al-takes-all.At that age, Al looks like an adult. Her parents gave Al permission to sell newspapers, snacks, and candy at the Railway Station, he was also allowed to do business selling fruits and vegetables.At the age of 15 years, Al has mastered the basic principles accepted the job after working as one in a thousand successive telegraph operator in the American civil war. 

It was then that he had a golden opportunity to improve the speed and efficiency in sending and receiving Morse code practice equipment and experiments are designed to improve the tool.At the age of 16 years, having worked in various telegraph office, and came to the discovery of the so-called first-automatic repeater (automatic repeater) - that can conduct signals between the stations are empty. So it allows people to easily and accurately translate Morse code without any interruption. Strangely, he never patented it homemade.In 1879, Al received extreme disappointment when Alexander Graham Bell had beaten her. Bell had patented a device Conductor of the human voice.

Yet when it was Edison's creations have also developed a tool that can deliver the human voice.His disappointment did not deter her. Edison began to walk to the discovery of an electric incandescent bulb.In 1880, Edison and his friends make at least 3000 different theories to develop an efficient incandescent lamps. Incandescent lamp shining through an electric current by heating a thick slab of material (called a filament / wire coil) until hot enough to make the light shine.In Edison biography of a writer noted "his mother is a teacher who is completely and do the best for his students, he took Edison to learn for himself the stage, the stage of learning to make her interested and entertained, he gave encouragement to keep going in that area. one of the best things he can do against the child's extraordinary. "Thomas Alva Edison himself gives the impression of his mother "Ibundaku have shaped me. He understands me, and he let me follow my talent. "

Thomas Alva Edison (February 11, 1847 - October 18, 1931) was an inventor and businessman who developed many important devices. The Wizard of Menlo Park is one of the first inventors to apply the principles of mass production in the discovery process.Edison is considered as one of the most prolific creator of his day, holding a record 1,093 patents in his name. Most of these findings is not entirely original, but it is an improvement earlier patents, and in fact created by the many employees - Edison was frequently criticized for failing to include the name of its employees. Nevertheless, Edison received patents worldwide, including the United States, United Kingdom, France, and Germany.Edison founded the Motion Picture Patents Company, which is a conglomerate of nine major film studios (commonly known as the Edison Trust). He also helped in the field of defense the United States government. Some of his research include: detection of the aircraft, destroying periscopes with machine guns, submarine detection, stop the torpedo nets, increasing the power of the torpedo, the ship camouflage, and many more. He was born in Milan, Ohio, USA. He died at the age of 84, on the anniversary of the famous inventions, modern light bulb.
