A hundred words of Edison s introduction, how to write a simple introduction to Edison s life?

Thomas Edison (1847-1931) was a famous American inventor. He worked almost ten hours a day for decades, and read 3 to 5 hours in the study at night. So, on the day of Edison's 79th birthday, he proudly said to people, I am already 135 years old.

He lived to be 84 years old and made as many as 1,100 inventions during his lifetime, the greatest of which was the invention of the phonograph and the automatic telegraph, experimenting with and improving the incandescent lamp and **. Edison began to study electric lighting in his early 20s, and for more than 10 years, he successively chose bamboo cotton, graphite, tantalum ......and so on thousands of different substances as filament materials for testing, often through the sky, once he and his assistants worked for 5 days and nights. In 1879 Edison used carbon filament as an incandescent filament and lit it for 40 hours.

Because the surface of the carbon filament is porous, brittle, and the strength is very low. It was soon replaced by tungsten wire.

In 1883, Edison discovered the phenomenon of thermal electron emission, also known as the "Edison effect", that is, some electrons or ions near the metal surface get enough kinetic energy for their irregular movement due to high temperature, overcome the constraints of the surface, and escape from the metal. The Edison effect is essential for the operation of any vacuum tube, and the cathode, which is the emitting surface, is often coated with a layer of alkaline earth metal oxide to facilitate the emission of electrons, and heated with an electric current to maintain high temperatures.

In 1900, Edison invented the iron-nickel battery, which is an alkaline battery with an electromotive force of about 1 3 1 4 volts, which has a long life but is not very efficient. Edison made many inventions in his life, but when others asked Edison about the reason for his success, he said: Some people think that I have some genius, which is not true, "genius" is one percent inspiration, ninety percent of inspiration.

You've heard of the inventor of the light bulb, Shiram Maxim.

Sir Hi is an American inventor and entrepreneur with numerous important invention patents, and was awarded the title of "Wizard of Menlo Park" by the media, and was the first inventor in the world to use the principle of mass production and his industrial research laboratories to produce inventions. ram maxim)? In fact, Maxim was with Thomas Edison.

One of the many inventors who worked on the light bulb at the same time should be regarded as one of the first developers of this technology. But Edison is recognized as the inventor of the technology, why?

In the end, Edison's light bulb proved to be slightly more technically superior than other designs of his time. But the main reason why Edison's name will always be associated with the light bulb is his ability to shape an environment that commercializes his inventions. In 1879, when Edison first showed his light bulb to the public at Menlo Park, he announced:

We will make electricity so cheap that only the rich will be willing to light candles. Just two years later, he built the company's first power station in Manhattan.

Downtown. Within five years, the Edison distribution network had covered more than 120 power stations, supported by inventions such as the Edison giant generator, the Edison electric feeder and parallel distribution.

But Edison did not limit his shaping activities to the material realm, he also sought to conquer the hearts and minds of his shareholders. For example, when alternating current.

technology against direct current.

When technology challenged and jeopardized his power distribution system, Edison launched a PR campaign to convince the public and regulators that the new technology was unsafe.

More than a century later, many companies are deploying similarly powerful shaping strategies to gain an edge in some of the industries, sectors, and geographies that are undergoing profound change. For example, Novo Nordisk, a global healthcare company, has joined forces with regulators, doctors and patients to create diabetes in China.

market, thus bringing great benefits to its development. By opening up its platform to outside developers, Facebook has built an ecosystem that outperforms its competitors. Southwest Airlines has successfully reinvented mature markets with disruptive innovation.

Like Edison, these companies understood that to operate in an environment that was not malleable but highly malleable, they had to use a shaping strategy. Here's how they managed to do it in seemingly disparate markets.

Edison was a great inventor.

EdisonBorn in the United States in 1847Ohio。He invented more than 2,000 inventions during his lifetime. He not only became one of the most outstanding scientists in the history of modern physics, but also known as the world's greatest inventor

The greatest contribution of Edison's life was the invention of the electric light. He did more than 1,600 experiments on heat-resistant materials and more than 600 plant fibers before he made the first light bulb. Later, he continued to improve the manufacturing method on this basis.

In order to popularize the use of electric lights, he developed various additional equipment for electrical systems such as parallel circuits, fuses, insulating materials, copper wire networks, etc.; It also manufactures a generator with stable voltage and a three-wire switch for economic power distribution. In 1882 he built an electric power grid in New York. Although he uses direct current.

The transmission method limits the distance that can be transmitted, but this great contribution has greatly improved human life.

The way to commemorate Edison after his death

At 3:24 a.m. on October 18, 1931, at his home in Orange, New Jersey, Edison died peacefully in his sleep at the age of 84.

In honor of Edison, USA**.

ordered a nationwide power outage for 1 minute, and at 6:59 on October 21, Hollywood and Denver turned off the lights; 7:59 a.m. Eastern United States.

power outage for one minute; 8:59 a.m., Chicago.

Trams and elevated subways are out of service; From the Mississippi River Valley to the Gulf of Mexico, darkness reigned; Liberty, New York.

The torch was extinguished at 9:59 a.m.

In this minute, it was as if the United States had returned to the era of kerosene lamps and gas lamps, and a minute later, the lights were shining again from coast to coast.

Thomas Edison, an American scientist, inventor, and entrepreneur with many important invention patents, was awarded the title of "Wizard of Menlo Park" by the media, and was the first person in the world to use the principle of mass production and his industrial research laboratory to invent. He is also an alumnus of Cooper Union College.

Edison invented many things, including the gramophone, electric light, moving movie camera, and direct current power system, which had a great impact on the world. In the United States, Edison holds 1,093 patents, and he has more than 150 patents in the United States, the United Kingdom, France, and Germany.

Two of the greatest patents of his life were the gramophone, which preserves and taste, and the other is the controversial patent, the electric light, which ended in Edison's successful patent after six years of lengthy court battles.
