Joule, a famous British scientist, loved physics since he was a child. He often does some experiments about electricity and heat by himself. One holiday, Joule and his brother traveled to the suburbs. Joule, who is clever and studious, never forgets to do his physics experiments even when he is playing.

He found a lame horse, led by his brother, and quietly hid behind him. He used a volt battery to electrify the horse, trying to see how the animals reacted after being stimulated by the current. As a result, the reaction he wanted to see appeared. The horse jumped wildly after being shocked and almost kicked its younger brother.

Although the danger has appeared, it has not affected the mood of little Joule who loves to do experiments. He and his brother rowed the boat to the lake surrounded by mountains. Joule wants to see how big the echo is here. They filled the musket with gunpowder and then pulled the trigger.

Who knows "bang", a long flame spouted from the muzzle and burned Joule's eyebrows, almost scaring my brother into the lake. At this time, the sky was covered with thick clouds, lightning and thunder. Joule, who just wanted to go ashore to take shelter from the rain, found that it took a long time to hear the thunder after every lightning.

Joule didn't take shelter from the rain, dragging his brother up a hill and carefully recording the time of lightning and thunder with his pocket watch. After school started, Joule almost wanted to tell the teacher all the experiments he had done and ask for advice from the teacher.

The teacher smiled at Joule, who was eager to learn and curious, and patiently explained to him: "The speed and harmony of light are different. The speed of light is fast and the speed of sound is slow, so people always want to see lightning before hearing thunder, but in fact lightning and thunder happen at the same time. "

Joule suddenly realized. Since then, he has been more fascinated by learning scientific knowledge. Through continuous study and careful observation and calculation, he finally discovered the mechanical equivalence of heat and the law of conservation of energy, and became an excellent scientist.

2. Edison: Telegraph fan and newspaper fan.

Edison is a famous invention king in the world. He invented 1000 items, such as electric lights, phonographs and film machines. However, when Edison was a child, he only went to school for a few years because his family was poor. At the age of twelve, he went to the train to sell newspapers. If he can't go to school, he will teach himself. He loves learning very much. He sells newspapers while reading them, taking time to study and do experiments.

Edison's father is strict with his family at ordinary times. He stipulates that the whole family must turn off the lights and sleep before 1 1 half past one every night. But Edison often comes home at eleven o'clock in the evening after selling newspapers, and there is no time to do his favorite experiments after returning home.

This is unbearable for Edison who likes to learn and explore by himself. So he thought about it and finally came up with a good way to get his father to support himself in the experiment.

One day, Edison put a wire on the tree with a copper wire, which was directly connected to his good friend's house, leaving the newspaper and a telegraph machine left at his friend's house. When he comes home at night, his father wants to read the newspaper. Edison said today's newspaper was sold out. At first, his father was not very sorry.

In order to arouse his father's interest, Edison began to talk about how fresh and interesting the contents of today's newspaper are. It is a pity that he didn't read it. Edison's father listened to him so vividly that he wanted to see it. So he asked Edison if he could find another one.

Edison said that his friend Gary had another copy, and he could send out the contents of the newspaper by telegram. At this time, Edison's father was addicted to reading newspapers, so he promised him happily.

Edison's father was very happy to see that his son's homemade telegraph really worked. Since then, he has never stopped Edison's telegraph experiment at night. Later, Edison worked hard and finally became a great scientist in the world.

3、

Zhuge Liang studied under Mr. Si Mahui, a water mirror. Because he studied very hard and was good at thinking, he got excellent grades and was deeply loved by his husband.

However, Zhuge Liang loves reading too much. He has too many questions and her husband's knowledge is too profound. For a time, Zhuge Liang couldn't wait for class every day and always listened to the teacher.

Zhuge Liang, who is eager to learn more, always tries his best to ask Mr. Wang to postpone the class for a while, but Mr. Wang finishes the class as soon as he hears the cock crow and never delays. I'm so anxious that Zhuge Liang really wants to beg the rooster, hoping it won't crow so punctually every day.

Zhuge Liang, who never gave up easily, found through careful observation that Mr. Wang's little bookboy had a fixed time to feed the chickens, so he secretly brought some food and secretly fed some to the cocks before class. This trick really works. The rooster may be too full, so he will be lazy and stop barking. Mr. Shuijing's class will be extended a lot, and Zhuge Liang is very happy.

After a few days of this life, Mr. Shuijing found the problem. He called his little boy to his side and asked him if he fed the rooster regularly. Little extremely naive answer: "I have been feeding chickens according to my husband's instructions." Mr. Water Mirror touched his beard and lost in thought.

In class the next day, he asked with a serious face: "We have all read sage books and learned benevolence, righteousness and honesty. Now, who can tell me why the cock doesn't crow on time? " The students all looked blank and at a loss.

Only Zhuge Liang played drums in his heart. Finally, he stood up and confessed his mistake, saying that he secretly fed the chickens in order to attend more classes. The old gentleman was very angry and shouted in public, "You don't deserve to study here. Go home. "

Zhuge Liang didn't expect that he would make things out of control in order to listen to the teacher's teachings more. He knows that Mr. Wang is angry now and he won't listen to anything he says. After much consideration, he felt that his wife was easy to talk to, so he went to Mr. Wang's house and begged her to put in a good word for him.

The lady said earnestly, "Although he is still young, he lied to you, but his starting point is just to listen to your class for a while, which is completely different from what ordinary secular people want." Can't you see the child's heart after living together for so long? "

Can't you see the child's heart after living together for so long? " Later, Mr. Shui Jing felt that he had gone too far, so he left Zhuge Liang and continued to learn from himself.

4. Wang Yanan

When I was a child, I was ambitious and loved reading. When he was in middle school, in order to gain more time to study, he deliberately sawed off the 1 foot of the wooden bed where he slept and turned it into a three-legged bed. Every day, he reads until late at night. Go to bed when you are tired, then turn over in confusion, and the bed will tilt in the direction of his short feet. He was suddenly awakened and immediately got out of bed and read on his desk. Every day, without interruption.

As a result, he achieved excellent results every year and was regarded as one of the three outstanding figures in his class. He studied hard as a teenager and later became an outstanding economist in China.

5. Madame Curie

Madame Curie's original name was Marie Skoro Dovska. Mary was born and brought up in Poland. Mary's mother died when she was very young, and her father lost his job because of the national subjugation. He only relies on his previous savings to teach other children in his family to earn some money to support themselves. Life at home is very difficult.

Mary graduated from middle school. Because of her outstanding talent, she won a gold medal. But she can't go on to school. Because I study in Paris, my family can't afford that much money. She discussed with her sister that she should be a tutor first and let her study. You can work for her after graduation.

In this way, my sister went to Paris with the money raised by the whole family. Mary earned money while studying, and finally 189 1 entered the Faculty of Science of Paris University. When Mary arrived in Paris, she moved to a small attic near the school.

The conditions in the attic are quite difficult, and it can't be heated in winter. Mary is often awakened by the cold. She has to get up, cover all her clothes, and sometimes even put a stool on her body to increase her weight. Mary's life is extremely simple. She only eats a few slices of bread every day. She forgot this several times. She was reading a book when she suddenly fainted. Thanks to her classmates' discovery, she informed her sister.

All the hard conditions didn't affect Mary's study at all. She always comes to the classroom early every day, sits in the front seat and listens to the teacher carefully. At night 10, the lights in the library went out, and she reluctantly left and went back to her hut. Kerosene lamps are often turned on at two or three in the evening.

In just two years, she got two master's degrees in physics and mathematics. The pale girl in a shabby sweater graduated from Paris University with the first prize 1893.
