Euler was born in 1707 in Basel, Switzerland. When he was a child, he liked mathematics very much. He began to teach himself algebra when he was below 10. Even several of his teachers haven't read the book, but little Euler read it with relish. When he meets something he doesn't understand, he marks it with a pen and then asks others for advice afterwards. /kloc-When he was 0/3 years old, he went to university of basel to study, which was a miracle at that time and once caused a sensation in mathematics. Little Euler is the youngest student in this university and even in the whole Swiss university campus. In college, I got the careful guidance of johann bernoulli (1667- 1748), the most famous mathematician in calculus at that time, and gradually established a deep friendship with him. Johann bernoulli later praised shine on you as better than the students in Lanzhou: "When I introduced Advanced Analysis, he was still a child, and you brought him up." Two years later, in the summer, Euler received a bachelor's degree from university of basel, and the following year, Euler received a master's degree in philosophy from university of basel. 1725, Euler began his mathematics career.

Hua

After graduating from junior high school in China, because of his poor family, he could not enter senior high school, so he had to study accounting in the Chinese vocational school founded by Huang Yanpei in Shanghai, in order to find a career similar to accounting to support his family. In less than a year, due to the high cost of living, I was forced to drop out of school and go back to Jintan to help my father manage the grocery store. In the monotonous life of standing at the counter, he began to teach himself mathematics. When he returned to his hometown, he continued to study mathematics while working for his father in a grocery store with only a small facade. Recalling the time when he studied hard, his sister Hua Lianqing said, "Although it was winter, Luo Geng was still reading his math book at the checkout counter. Snuff running down, he wiped his nose with his left hand and threw it aside. He didn't get rid of it, so he stretched out his right hand and kept writing ... "

At that time, Luo Geng stood in front of the counter. When the customer came, he helped his father do business, do abacus and keep accounts. As soon as the customer left, he buried himself in reading and solving math problems. Sometimes I am in a daze, forget to receive the customer, and even take the calculation result as the payment payable by the customer, which surprises the customer. Because similar inexplicable things often happen, after a long time, his neighbors treat him as a joke, and everyone has nicknamed him "Luo Daku". Whenever something happens that neglects customers, my father is angry and anxious, saying that he is too tired to read the "heavenly book" and wants to burn the book forcibly. When there is an argument, Hua always clings to the book.

Jingrun Chen

Chen Jingrun doesn't like walking in the park or walking in the street, but he likes studying. When I study, I often forget to eat and sleep.

One day, Chen Jingrun touched his head during lunch. Alas, his hair is too long. He should get a haircut at once, or others will think he is a girl. So he left work and ran to the barber shop.

There are so many people in the barber shop that everyone cuts their hair next to each other. Chen Jingrun's brand is the small brand number 38. He thought it was too early for me to turn now. Time is so precious that I can't waste it. He hurried out of the barber shop, found a quiet place to sit down, then took out a small notebook from his pocket and recited new words in a foreign language. He recited it for a while and suddenly remembered that when he was reading a foreign language in the morning, there was one place he didn't understand. You must understand what you don't understand. This is Chen Jingrun's temper. He looked at his watch. It's only half past twelve. He thought: check in the library first, and then come back for a haircut. He stood up and left. Who knows, not long after he left, it was his turn to get a haircut. The barber's uncle shouted, "Number 38! Who is number thirty-eight? Come and get a haircut! " Think about it. Chen Jingrun is reading in the library. Can he hear the barber's uncle calling number 38?

newton

"I must pass him!"

When it comes to Newton, people may think that he must have been a "prodigy" and "genius" when he was a child, with extraordinary intelligence. In fact, Newton's childhood was thin and his mind was not smart. When I was studying in my hometown, I didn't study hard and got poor grades in my class. But he has a wide range of interests and his game skills are higher than those of ordinary children.

Usually he likes to make mechanical models, such as windmills, waterwheels, sundials and so on. His elaborate water clock has won people's praise for its accurate timing.

Sometimes, the way he plays ball is also very strange. One day, he made a lantern to hang on the tail of a kite. When night falls, the lighted lanterns rise into the air with the help of the rising power of kites. Luminous lanterns flow in the air, and people are frightened and think there is a comet. Nevertheless, he is often discriminated against because of his poor academic performance.

At that time, the hierarchy of British feudal society was very serious. Students who study well in primary and secondary schools may discriminate against those who study poorly. There was a game between classes. When everyone was in high spirits, a good student kicked Newton and called him an idiot. Newton's mind was stimulated to extreme anger. He thought, we are all students. Why should I be bullied by him? I must pass him! From then on, Newton made up his mind to study hard. He gets up early and goes to bed late. Every minute counts. He studies hard and thinks hard.

After studying hard, Newton's academic performance improved continuously, and soon surpassed the classmate who had bullied him, ranking first in the class.
