What did Edison invented?

Thomas Edison
1847 ～ 1931
The invention King Thomas Alva Edison was born in 1847 in Milan Town, Ohio. He has only been educated for three years. Students with dull intelligence!

Itheng made his first invention when he was only twenty -three years old -electronic voting recorder, such instruments did not sell. Enter the market. Shortly after the inventor was invented, Edison invented an improved stock market automatic transmitter in exchange for 40,000 US dollars, which was a huge income at the time. Edison then made a series of other inventions, and soon paid fame and fortune. Perhaps his most creative invention was a vocalist, and in 1877 he obtained the patent right of the invention. But for the world, he was more important to invented a practical incandescent bulb in 1879.

The first person to invent an electric lighting device is not Edison. A few years ago, Paris used a lone light for street lighting. However, Edison’s light bulbs, together with the transmission device he invented, enabled ordinary families to realize the use of electricity. In 1882, his company began to produce domestic electricity in New York City. Since then, the use of electric families has spread throughout the world.

Edison established the first transmission company to send electricity to a private home, laying the foundation for the development of a huge industry. After all, today’s power supply is not just electric lights, but a complete set of household appliances from televisions to washing machines. Because Edison’s power grid was easy to use, it greatly promoted the application of electricity in industry.

Edison has made great contributions to the development of movies, cameras and projectors. His telephone (his carbon essence sender has significantly improved visibility), telegram and hitting only the crispy plaque. Tuo 亍 芗 芗 鹄 鹄 鹄 鹄 竦 竦 竦 竦 竦 ф 龅 ハ罘 ⒚ ǎ ǎ ǎ ǎ 獾 獾 桓 桓 桓 隽 隽 四 氖 氖 氖 氖 氖
Itmong’s work efficiency is so amazing. One of the reasons is that in the early days of his career, he established a research laboratory in Mood Park, New Jersey, and hired a group of talented assistants to help him do work. Since then, many industrial companies have established large -scale research laboratories, and their prototypes are Edison’s laboratory. The modern and well -equipped research laboratory founded by Edison -many people in the laboratory as a overall work -it is one of his most important inventions, although he will definitely not obtain patent rights although he will not obtain patent rights.

Itong is not only an inventor, but also engaged in manufacturing, and formed several companies. The most important companies later became general electrical companies.

. Although Edison did not have the temperament of pure theoretical scientists, he made an important scientific discovery. In 1882, he found that the current can be passed between the wires that do not contact each other in the state of vacuum. This phenomenon is called the Edison effect. The establishment of industry.

It’s most of his life suffered from severe deafness, but he worked hard and perseverance, so he completely compensated this defect. Edison has been married twice

(his first wife died when he was young), and both wives gave him three children. He died in Olan, New Jersey in 1931.

The people recognized that Edison is a genius and the greatest invention of heaven that has appeared. Browse his practical invention results, a sense of awe spikes, although most of the inventions may be made by others within 30 years. But if we look at his invention separately, we will find that none of them have real significance. For example, although incandescent lamps are widely used, it is not an irreplaceable gap in modern life. In fact, the invention made by the use of a completely different principle of fluorescent lamps is also widely used; if there is no incandescent bulb at all, our daily life will not be very different from the present. Indeed, before there are electric lights, people generally think that candles, oil lamps and gas lamps are quite satisfactory light sources.

of course, the voice machine is a clever instrument, but people think that it is compared to the changes brought about by the radio, television or telephone to us in daily life. And in recent years, there have been completely different recording methods, such as tape recorders. If there is no spoken machine or a recorder today, it is relatively irrelevant. Many of the patent rights obtained by Edison are reforms made by devices that have been invented by others and are quite useful. Although such reforms are beneficial, they cannot be considered in the entire historical process.

The although there is no single -handed chicken group in Edison’s invention, it should be remembered that he is not just a invention, but a thousand species. It was for this reason that I ranked Aidon’s ranking in front of Gaglmo Marcney and Alexander Graham Bell.

Thomas Alva Edison is a world -renowned American electrical scientist and inventor. In addition to the inventions and contributions in the aspects of spoofing machines, electric lamps, electric
, telegraphs, movies, etc., in There are also many famous creations in the fields of mining, construction, chemical industry and other fields. Edison has a total of about 2,000 creations in his life, making great contributions to human civilization and progress.
Iddie was born on February 11, 1847 in Milan Town, Ohio, Midwest, USA. The father is the Dutch’s
descendants of the Dutch. His mother has been a primary school teacher and is the descendant of the Scottish. When Edison was 7 years old, his father started a roof tile business at a loss, and
The family moved his family to Gratotberg in the northern suburbs of Small Michigan. Soon after moving here, Edison suffered from scarlet
, and he was sick for a long time. People thought that this disease was the cause of deafness. Edison went to school at the age of 8, but only read
for three months, and was scolded by the teacher as “low energy” and went out of the school gate. Since then, his mother is his “tutor
division”. Due to the good educational method of his mother, he had a strong interest in reading. “He not only shows the group books, but also
, but also at a glance, he has recited it.” At the age of 8, he read the most important drama writer Shakespeare,
Dickens’ works and many important historical books during the British Renaissance. By the age of 9, he could quickly understand books that are more difficult, such as Parker
“Nature and Experimental Philosophy”. At the age of 10, he loved chemistry. At the age of 11, he experimented with his first telegram. In order to make money to buy
, he started his work. At the age of 12, he got the work on the train on the train and moved between the Hugen Port
and the Detroit of Michigan. While selling newspapers, he also made fruit and vegetable business. As long as he was free, he went to the library
reading books. He bought an old printing machine and started publishing his own weekly, “Pioneer”, and the first issue was printed on the train
. He built a chemical laboratory on the luggage car with the money he earned. Unfortunately, there was a chemical medicine on fire,
This with his equipment was thrown out of the car. Another time, when Edison was trying to board a row of freight trains, a column
The car staff grabbed his two ears to help him get on the car. This action has led Edison to become a lifelong deaf.
In August 1862, Edison rescued a boy who was about to be killed on the train track with a fearless hero. Children
The father’s father was grateful to Dade, but because he had no money to pay for the return, he was willing to teach him telegram technology. Since then, Edison has had a relationship with the new world of mysterious electricity and embarked on a scientific journey.
In 1863, Edison served as telecommunications officer of the Draord Hub Station. From 1864 to 1867
, he served as a reporter in all parts of the central and western regions and lived a wandering life. Footprints come, including Straford, Edry
Ans, Wayneburg, Indiana Polis, Cindinnati, Nashville, Tennessee, Memphis, Louisville, Houlun n and other places Essence
In 1868, Edison came to Boston as a reporter. In the same year, he obtained the first invention patent right.
This is a device that automatically records votes. Edison believes that this device will accelerate the work of Congress, and it will be welcomed
. However, a member of a parliament told him that they had no intention of speeding up the agenda, and sometimes voting slowly was because of the needs of politics
. Since then, Edison has decided not to engage in any invention that people do not need.
In early June 1869, he came to New York to find a job. When he was waiting for the call in a broker’s office, a telegram was broken. Edison is the only person who can repair the telegram, so he has obtained a job that is better than he expected
. In October, he and Pop set up a “Pop -Edison Company” to operate science
instruments specializing in electrical engineering. Here, he invented the “Edison Pu”. He dedicated the printing machine to the
manager of a large company in Wall Street. He wanted to ask for $ 5,000, but he lacked the courage to say exports. So he asked the manager to give a price, and the manager gave
40,000 US dollars.
Iton built a factory in Ward Street, New Sawak, New Jersey, to build a factory to make various electrical machinery.
This working all night. He cultivated many capable assistants, and at the same time, he also happened to meet the diligent Mary, his first
bride. In Newvac, he made inventions such as wax paper and oil printers. From 1872 to 1875, Edison successively invented the dual and quadruple telegraph machines, and also helped others to become the world’s number one. Set in English.
1876, Edison moved again, and this time he moved to the “Monroe Park” in New Jersey. Here he
has built the first “invention factory”, which “marks the beginning of collective research.” In 1877, Edison improved the early

The invention King Thomas Alva Edison in 1847 was born in Milan, Ohio. He has only been educated for three years. Slow students!

Edison has made great contributions to the development of movies, cameras and projectors. He has made important improvements in the telephone (his carbon essence sender significantly improved), telegram and typo. There are voices, oil printers and batteries in other inventions. In total, Edison has obtained more than a thousand single inventions of patent rights, which is indeed an incredible number.

Today, it is difficult for us to imagine that there is no electricity in life -a lamp cannot be turned on, listening to records, going to the cinema, or calling someone. However, all these things we think for granted are the result of a practical invention and creation -he is Thomas Edison. Before Edison, on the road, the living room, the factory, only the drowsy gas lamps were used by hand. As soon as the night fell, the factory closed. Electricity or telephone was not invented by Edison. But his practical invention and improvement pushed the use of electricity and telephone to every corner.

Idson may be the greatest inventor in history. He opened the precedent of modern world technological innovation. The tireless inventor brought us into the 20th century from the era of steam.

2. Edison also has many famous inventions in movies, trams, mining, architecture, and weapons.

3. Edison also observed the phenomenon of thermal electron launch in a vacuum bulb. Later generations called it “Edison Effect”. The discovery of thermal electron launch laid the foundation for the development of electronic tube.
