English speech on Edison as a great scientist, three minutes

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.

His strong research spirit led him to make a significant contribution to the improvement of human lifestyles.

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

After a long time, he asked, "How much capacity?" He didn't hear it, but turned his head to see the assistant measuring the circumference and slope of the bulb with a soft ruler, and took the measured number and lay it on the table to calculate.

He said: "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." ”

Do you need it? No one knows me in New York. Edison didn't care.

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! ”

Do you need it? Everybody knows me here. Edison still didn't care.

Writing about Edison I personally think a few points:

1. Edison's contribution to mankind.

2. Edison's spirit of finding a way out of life under difficult conditions, but still tirelessly carrying out his own inventive activities.

3. Edison did not go to school much in his life, and his education level was not high, but he made great contributions to mankind, and compared with the current highly educated spine members, he was more or less idle and did not know how to be practical.

So I recommend:

1. The inventor Edison was introduced from the light bulb commonly used in daily life.

2. Briefly introduce Edison's life resume (in addition to his great and wild faction, it is probably Edison's family miserable, sick and disabled, struggling and ridiculed).

3. Talk about Edison's contribution to mankind and his spirit of invention and creation in adversity.

4. Compare the current situation of society, according to your age stage, compare your peers, and explain what your peers lack.

5. Finally, of course, call on your peers. Learn from Edison. Or call for the lack of the spirit of exploration, invention, and creativity because of the comfort of society.

Einstein made a small bench when he was a child, and the careless teacher thought he was not good, but in fact, little Einstein tried 2 by himself, which has far-reaching implications. To educate children, it is recommended to check out the children's class, which is full of them.
