1 At the beginning of the article, it was written that on Edison's 81st birthday, friends in New York held a party, what role did it play?

2 Why did Edison devote himself so much to the research and production of rubber?

3 In the minute before and after the lights were extinguished in mourning for Edison, what was the expression of the world from "one darkness" to "one light"? Please combine the functions and benefits of writing like this in the original text.

4 "Not only do we live to receive his favors and benefits, but above all we inherit his spiritual legacy! What do you think is Edison's "spiritual legacy"?

5 A well-known psychologist said that "work, love, and play" are the three most important aspects of life, and one cannot be considered a mentally healthy person if one neglects any of them. "And the voice of love is working even on his birthday, do you think he is a mentally healthy person?

Please share your thoughts in conjunction with the article.

Answer] 1 On his 81st birthday, a feast was held for him by his friends, but he himself was unable to attend, a plot that strongly highlights Edison's spirit of selfless work.

2 A love of scientific research has always been his quality; to challenge a completely new goal (or: the study of rubber is a completely new discipline for him); For the development of the United States (or "to change the situation of American rubber imports").

3 Create a stark contrast between light and darkness. It highlights that Edison led the world to the light, made great contributions to mankind, and expressed the admiration of future generations for Edison.

4 (1) The attitude of diligence and selflessness, as he himself said: "There is nothing of real value in the world that can be obtained without hard work", "invention is one percent cleverness and nineteen percent diligence".

2) A great ambition for the benefit of all mankind, as he said: "My philosophy in life is to work, to reveal the wonders of nature for the benefit of mankind." That's right).

5 Example 1: According to this psychologist, Edison was indeed a mentally unhealthy person, his whole life was his career, his life was unusually monotonous, and he even sacrificed his birthday and the opportunity to reunite with his family, but he made great contributions to mankind, so to speak, sacrificing his love and games, but bringing good news to all mankind, which is more meaningful.

Example 2: Psychologists are talking about the situation of ordinary people, hoping that people can feel life in a comprehensive way. Although there were no games in Edison's life, he said on his deathbed:

I have done my best for the happiness of mankind, and there is nothing to regret! It can be seen that his life is full and meaningful, and games are to make people relax and enjoy happiness, and Edison has obtained these in his work, and everyone's pursuit is different, and we can't fit it all. Edison's spirit is not only healthy, but also full of strength.

That's right).

Satisfied, I wish you progress in your studies

At the beginning of the article, it is written that Edison's friends in New York held a banquet on his 81st birthday, and on his 81st birthday, his friends held a banquet for him, but he himself could not participate.

Edison attended elementary school for only three months in his life, and his learning was acquired through his mother's teaching and self-study. His success should be attributed to his mother's understanding and patient teaching since childhood, so that Edison, who was originally considered an imbecile, grew up to become a world-famous "king of invention".

Edison was curious about many things from a young age, and he liked to experiment with them until he understood the truth. When he grew up, he devoted himself to research and invention according to his interests in this area. He established a laboratory in New Jersey and invented more than 2,000 things in his lifetime, including electric lights, telegraphs, phonographs, motion picture machines, magnetic ore separators, crushers, and so on.

Edison's strong spirit of research led him to make significant contributions to the improvement of human lifestyles.

One day, while working in a laboratory, Edison handed his assistant an empty glass bulb with no light on and said, "Measure the capacity of the bulb." He bowed his head and worked again.

He said, "Time, time, how can it take so much time?" Edison came to him, picked up the empty light bulb, filled it with water, handed it to his assistant, and said:

The water in it was poured into a measuring cup and immediately told me how much it was. ”

The assistant immediately read out the numbers.

Edison said, "What an easy way to measure, it's accurate, it's time-saving, how could you not think of it?" Wouldn't that be a waste of time? ”

The assistant's face flushed.

Edison muttered, "Life is too short, too short, save time and do more!" ”

Edison was a poor worker before he became famous. Once, an old friend of his, met him on the street and said with concern, "Look at this coat on your body is not decently torn, you should change it to a new one." ”

A few years passed, and Edison became a great inventor.

One day, Edison ran into that friend on the streets of New York again. "Oops," the friend exclaimed, "why are you still wearing this torn coat?" This time, you're going to have to get a new one anyway! ”

In his later years, Edison, who was determined to forge ahead, once said something that stunned us: "Don't give me any more opinions in the future, because I have already thought about your ideas." And so the tragedy began.

In 1882, after the incandescent lamp was thoroughly accepted by the market, Edison's electric power company began to build an electricity grid, thus beginning the era of electricity. At the time, Edison's company relied on direct current to transmit electricity. Soon, alternating current technology began to emerge, but limited by the lack of mathematical knowledge and even more limited by the mentality of self-appreciation, Edison never recognized the value of alternating current.

Relying on his prestige, Edison gave speeches everywhere, spared no effort to attack alternating current, and even publicly ridiculed that the only use of alternating current was to kill people in electric chairs. The Westinghouse Company, which developed alternating current, was once overwhelmed by Edison.

One is not the same. Later, those who admired and superstitious Edison were surprised to find that alternating current is actually much stronger than direct current!
