A mathematician's short story

1785, 8-year-old Gauss was in the first grade of a primary school in rural Germany.

The teachers in the school are from the city. He has a prejudice that children in rural areas are not as clever as children in cities. However, he is very strict with his children's study. He hates students who don't pay attention in class and love to make small moves. He often beats them with a whip. Children like to listen to his class because he often talks about some very interesting things.

One day, he worked out an arithmetic problem. He said, "You calculate, 1 plus 2 plus 3, until 100?" Anyone who can't figure it out is not allowed to go home for dinner. "Say that finish, he sat in a chair, with eyes patrolling the students at my desk calculus.

Less than a minute later, little Gauss stood up with a small slate in his hand and said, "Teacher, I have worked it out ..."

Before Gauss finished, the teacher said impatiently, "No! Recalculate! "

Little gauss quickly checked it and said loudly, "yes, teacher!" " "Say that finish, he stepped down from his seat and put the small slate in front of the teacher.

The teacher looked down and was surprised to see "5050" written on it. He couldn't believe such a complicated math problem that an 8-year-old child worked out the correct number in less than a minute. You know, it took him more than an hour to get the question right three times. He suspected that others had asked little Gauss to work out the problem before. Just ask little Gauss, "How did you work it out?" Little Gauss replied, "I didn't add them one by one in the order of 1, 2, 3." Teacher, you see, the sum of two numbers at the beginning and the end of a head is the same: 1 plus1at 000, 1065438 at 2 plus 99+0, and 3 plus 98 is also 10 1 ...

Little Gauss's answer surprised the teacher. Because this is the first time he knows this algorithm. He looked at little Gauss in surprise, as if he had just met the son of a ragged bricklayer. Soon, the teacher specially bought a math book for Xiao Gauss, encouraged him to continue his efforts, and recommended Xiao Gauss to the education authorities for free education. Later, little Gauss became a world-famous mathematician. In memory of him, people called his calculation method "Gauss Theorem".

The story of flowers

Hua, a famous mathematician, was disabled by illness when he was young. After several ups and downs, he almost fell into a desperate situation.

After graduating from middle school, he was forced to drop out of school because he couldn't afford the tuition. Back to my hometown, while helping my father to work, I continued to study and teach myself tenaciously. Soon, he was infected with typhoid fever and his life was dying. After lying in bed for half a year, although he recovered, he left a lifelong disability-deformity of the left leg joint and limping. He was only 19 years old at that time. In that confused, confused and almost desperate day, he thought of Sun Bin behind Sun Tzu's Art of War. "The ancients can still be physically and mentally disabled. I'm only 19 years old, so there's no reason to give up. I want to replace my imperfect legs with a sound mind! " Young Hua is so tenacious in fighting against fate. During the day, he dragged his sick leg, endured severe joint pain and worked with crutches. In the evening, he taught himself late into the night under the oil lamp. 1930, his paper was published in Science magazine, which alarmed Professor Xiong Qinglai, head of the Department of Mathematics of Tsinghua University. Later, Tsinghua University hired Huawei as a teaching assistant. On the campus of Tsinghua University, where famous artists gather, Hua served as a teaching assistant in the Mathematics Department. He also taught himself English, German and French in four years and published ten papers.

The story of Chen Jingrun.

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

One day, Chen Jingrun touched his head during lunch. Oh, his hair is too long. He should get a haircut quickly, or people will think he is a girl when they see him. 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?

After a long time, Chen Jingrun found something he didn't understand in the library, and then went to the barber shop happily. But he passed by the foreign language reading room, and there were all kinds of new books, which were really nice. He ran in and read another book. It was not until the sun went down that he remembered to cut his hair. As soon as he touched his pocket, the little sign No.38 was still lying well. But what's the use of his coming to the barber shop? This number is outdated.
