What were some of Edison s frustrations?

Edison. He is an outstanding genius inventor whose inventions have contributed greatly to all mankind.

As a child, Edison was particularly fond of "why", with the spirit of breaking the casserole and asking the question, and he also liked to experiment himself. Once, Edison saw the old hen hatching eggs, and he was very happy to learn from the hen, and it is conceivable that he broke a nest of eggs. But there's something worse!

Once Edison asked how the medicine was made, and his mother told him that he burned down the granary.

Edison was kicked out by his teacher after less than three months of school, why? It's because of so many of his problems. In desperation, Edison's mother Nancy could only take him home and buy him a copy of "Natural Science Experiments", and from then on, Edison developed a strong interest in scientific experiments.

At the age of 12, Edison worked as a little newsboy on the train, but because he brought experimental equipment on the train, there was a fire, and he was fired after eating a slap.

Finish. Edison was fired for using his invention in an improper way while he was at the railroad office.

As a newspaper operator, it is stipulated that a message be sent every hour after 9 o'clock every night, so Edison made an automatic transmitter, but he was found during a check, although the director admired him, but Edison was still fired.

At the age of 21, Edison had a small success and invented many objects, let's take a look

Look, this is the photocopier, Edison dipped the engraved roller on the paper and rolled it, and it was good, and it was invented, which helped many manufacturers a lot and was received by the world.

We know that ** was invented by Bell, but if it weren't for Edison's toner walkie-talkie, which improved the volume and sensitivity, what was the use of the unclear **?

Look, this is Edison's greatest invention of the electric light!! Edison worked tirelessly to do more than 1,600 heat resistance tests and more than 600 plant fibers.

The test finally made the center of the lamp, a move that caused a sensation in the United States.

Edison's never-ending invention helped us a lot, and without the photocopier, we would still have to copy by hand; If we don't, it's very troublesome for us to pass on the message; If there were no electric lights, we would have only used oil lamps until now.

In 1931, the great Edison is gone forever, although he passed away, but he and his more than 2,000 inventions will remain in our hearts forever!

In 1854, the Edison family moved from Milan to Fort Glattiot, a northern suburb of Port Huron, Michigan.

In 1855, he began school, and in just three months, he was kicked out of school by his teacher under the name of "imbecile".

Between 1864 and 1867, Edison worked as a newspaper operator in the United States, living a vagabond life with no security, during which time Edison changed ten places of work, five times he was dismissed, and five times he resigned himself.

At the end of 1868, Edison came to Boston as a newspaper operator, and in the same year he obtained the first patent for his invention, which was a device that automatically recorded the number of votes, known as the "vote counter."

In October 1869, Edison and Franklin Pope co-founded the "Pope-Edison" company, specializing in scientific instruments for electrical engineering, and at the same time invented the ordinary printing press.

In 1877, Edison improved the early ** machine invented by Alexander Bell and put it into practical use, and soon opened the ** company.

In September 1878, Edison began to study electric light, but due to Edison's financial problems, he had to find financial support, so he set up a joint-stock company to provide financial support for the experiment.

On October 21, 1879, when the electric lamp was developed, he tried nearly 1,600 materials for this purpose, and it took 45 hours before the filament of the electric lamp was burned out.

In 1881, at the Paris World's Fair, Edison exhibited a 27-ton power generation device that could be used to illuminate 1,200 electric lamps.

1. The story of the photocopier, at first, Edison's invention of paraffin paper was only commonly used in the packaging materials of food and candy, and later he tried to carve the outline of the text on the wax paper to form a paraffin lettering paper plate, and then used the ink roller to roll on the engraved paraffin paper, and the wonderful thing happened, and the clear handwriting appeared on the white paper. After many experiments, in 1976, Edison began to produce the photocopier he invented. All of a sudden, institutions, schools, institutions, and groups have adopted this kind of wax paper mimeographing machine.

Because of the popularity of Edison's photocopier, which became popular all over the world, Edison deeply experienced that it was necessary to invent something that was universally and deeply needed.

2. The story of the steam engine, Watt is a child of extraordinary intelligence, he is diligent and studious, brave to explore, and most interested in invention and creation. One day my father's friend came to visit, and I happened to see little Watt sitting by the stove in a daze, with a pen and paper in his hand, and many drawings on the ground. Once, the whole family went out of the house, leaving Watt alone as a janitor.

He stared blankly at the teapot on the stove, which was about to boil, and the lid of the kettle was lifted by the steam, and the ...... was lifted up and downHe thought: The power of this steam is so great, if you can make a bigger furnace and boil water in a large boiler, the water vapor produced will definitely be dozens or hundreds of times greater than this. Isn't it possible to use it to make power for all kinds of machinery to replace a lot of manpower?

This is the story of "Watt's invention of the steam engine" in later legends.
