Where was Gauss born?

Gauss (1777~1855) was born in Brunswick, located in what is now central and northern Germany. His grandfather was a farmer, his father was a plasterer, and his mother was the daughter of a mason. He had a very smart younger brother, Gauss. This uncle took great care of little Gauss and occasionally gave him some guidance. His father can be said to be a " "Big boss" believes that only strength can make money, and knowledge is of no use to the poor.

Gauss showed his extraordinary talent very early. At the age of three, he was able to point out errors in his father's account books. When I was seven years old, I entered primary school and was taught in a dilapidated classroom. The teacher was not kind to the students. He often thought that he was underappreciating his talents by teaching in a remote area. When Gauss was ten years old, his teacher took the famous "adding from one to a hundred" test and finally discovered Gauss's talent. He knew that his ability was not enough to teach Gauss, so he bought a deeper mathematics book from Hamburg. Read to Gauss. At the same time, Gauss became very familiar with Bartels, an assistant teacher who was almost ten years older than him. Bartels was also much more capable than his teacher. He later became a university professor and taught Gauss more and deeper mathematics.

The teacher and teaching assistant visited Gauss’s father and asked him to let Gauss receive a higher education. However, Gauss’s father believed that his son should be a plasterer like him, and he had no money for Gauss to continue his studies. The final conclusion is - find rich and powerful people to be Gauss's sponsors, although they don't know where to look. After this visit, Gauss was exempted from the work of weaving every night and discussed mathematics with Bartels every day, but before long, Bartels had nothing to teach Gauss.

In 1788, Gauss entered higher education despite his father's opposition. After seeing Gauss's homework, the math teacher asked him to stop taking math classes, and his Latin soon surpassed the class.

Hua Luogeng (1910-1982) was born in Jintan County on the shores of Taihu Lake in Jiangsu Province. When he was born, his father Hua Laoxiang placed him in a basket for good luck. Therefore, he was named Luo Geng.

Hua Luogeng has been playful since he was a child and likes to join in the fun, but his homework is mediocre and sometimes he fails. He reluctantly finished elementary school and entered Jintan Middle School in his hometown, but he was still playful and his handwriting was crooked. When he was doing math homework, he was distracted and drew seriously, but it was like graffiti. Therefore, when he was in junior high school, Hua Luogeng was still Students who are not liked by their teachers are often punished.

A teacher named Wang Weike at Jintan Middle School had a unique insight. After studying Hua Luogeng's scribblings, he discovered that the many erasures reflected the various approaches he explored when solving problems. Once, Teacher Wang Weike gave a lecture to his students on [Sun Tzu's Sutra] and asked this question: "There is something whose number is unknown. If you count three or three, you will be left with two. If you count five or five, you will be left with three. If you count seven or seven, you will be left with two. Ask about the geometry of the object." "While everyone was silent, a student stood up. When everyone saw it, it turned out to be Hua Luogeng, who had always been looked down upon. He was only fourteen years old at the time. Guess what Hua Luogeng said?

1. Chen Jingrun doesn’t like playing in parks or walking on the street, but he loves studying. When studying, I often forget to eat and sleep.

One day, when Chen Jingrun was having lunch, he touched his head and said, "Oh, my hair is too long. I should get it straightened out quickly. Otherwise, if people see it, they will think he is a girl." So he put down his job and ran to the barber shop.

There are many people in the barber shop, and everyone gets their hair cut next to each other. The brand Chen Jingrun took was the small brand No. 38. He thought: It's still early for my turn. Time is so precious, I can't waste it in vain. He hurriedly walked out of the barber shop, found a quiet place to sit down, then took out a small notebook from his pocket and memorized new words in foreign languages. After memorizing it for a while, he suddenly remembered that when he was reading a foreign language in the morning, there was something he didn't understand. If you don't understand something, you must understand it. This is Chen Jingrun's temper. He looked at his watch. It was only half past twelve. He thought: Go to the library to check it out first, and then come back before you can get a haircut, so he stood up and left. Who knows, not long after he left, it would be his turn to get a haircut.

The uncle barber shouted loudly: "Number 38! Who is number 38? Come and get a haircut!" Think about it, Chen Jingrun is reading in the library, can he hear the uncle barber calling number 38?

After a while, Chen Jingrun understood what he didn't understand in the library, and then happily walked to the barber shop. But he passed by the foreign language reading room. There were all kinds of new books, which were very nice. He ran in and read a book again. It wasn't until the sun went down that he remembered about getting a haircut. When he touched his pocket, he saw that the small sign with the number thirty-eight was still lying there. But what's the use of him coming to the barber shop? This number has long been outdated.

2. Archimedes

King Hiero of Syracuse asked a goldsmith to make a crown of pure gold. He suspected that it contained silver, so he asked Archimedes to make it. identification. When he entered the bathtub to take a bath, the water overflowed out of the basin, and he realized that although objects of different materials have the same weight, the water drained away will not be equal due to different volumes. Based on this principle, we can determine whether the crown is adulterated.

.In 1966, Chen Jingrun, who lived in a six-square-meter hut, borrowed a dim kerosene lamp, leaned on the bed, used a pen, and consumed several sacks of draft paper, and actually conquered the world. (1 2) in the famous mathematical problem "Goldbach's conjecture" has created a brilliance that is only one step away from picking up the crown jewel of number theory (1 1). He proved that "every big even number is the sum of a prime number and the product of no more than two prime numbers", making him a world leader in the study of Goldbach's conjecture. This result is internationally known as "Chen's theorem" and has been widely cited. This work also enabled him to win the first prize of the China Natural Science Award together with Wang Yuan and Pan Chengdong in 1978. His achievements in studying Goldbach's conjecture and other number theory problems are still far ahead in the world. A. Weil, a world-class mathematics master and American scholar, once praised him: "Every work of Chen Jingrun is like walking on the top of the Himalayas.
