Ariki Yuki, who told me a little story about mathematicians

Gauss (1777-1855), a famous German scientist, was born into a poor family. Gauss learned to do arithmetic on his own before he could speak, and one night when he was three years old, he watched his father calculate wages and corrected his mistakes in calculations.

When he grew up, he became one of the most prominent astronomers and mathematicians of our time. He made some contributions to the electromagnetism of physics, and one of the units of electromagnetism is now named after him. Mathematicians called him the "Prince of Mathematics".

At the age of eight, he entered a rural primary school. The math teacher was a man from the city, and he thought it was useless to teach a few young people to read in a poor rural area. And he is a little biased:

The children of the poor are born stupid, and it is not necessary to teach these stupid children to read, and if there is an opportunity, they should be punished to add some fun to this boring life.

It was a day of low mood for math teachers. When the students saw the teacher's depressed face, they cringed in their hearts, knowing that the teacher would arrest these students and punish them today.

You will count for me today the sum from 1 plus 2 plus 3 all the way up to 100. Whoever can't figure it out will be punished for not being able to go home for lunch. After the teacher said this, he picked up a ** without saying a word, sat on a chair and read it.

The children in the classroom picked up the slate and began to calculate: "1 plus 2 equals 3, 3 plus 3 equals 6, 6 plus 4 equals 10 .......""Some children add a number and then erase the results on the slate, and then add more, the number gets bigger and bigger, which is very difficult to calculate. Some of the children's faces were red, and some of them were sweating from their palms and foreheads.

In less than half an hour, little Gauss picked up his slate and stepped forward. "Teacher, is the answer so? ”

The teacher didn't raise his head, waved his fat hand, and said, "Go, go back and count again!" Wrong. He didn't think he would have an answer so soon.

But Gauss stood still and stretched out the slate in front of the teacher: "Teacher! I guess the answer is right. ”

The math teacher wanted to roar, but when he saw that the number was neatly written on the slate: 5050, he was amazed, because he had calculated it himself, and the number he got was also 5050, how could this 8-year-old kid get this value so quickly?

Gauss explained a method he had discovered, which was used by the ancient Greeks and Chinese to calculate series 1+2+3+....+n. Gauss's discovery made the teacher feel ashamed that he had not been right to look at everything and despise children from poor families. He also began to teach seriously, and often bought some math books from the city to study and lend them to Gauss.

With his encouragement, Gauss later made some important research in mathematics.

A short story of Chen Jingrun in mathematics.

Mathematician Chen Jingrun, while thinking about a problem, walked and hit the trunk of a tree without raising his head and said, "I'm sorry, I'm sorry." "Keep thinking.

A short story by the mathematician Rudolph.

In the 16th century, the German mathematician Rudolph spent his whole life calculating pi to 35 decimal places, which later generations called Rudolph's number, and after his death, others engraved this number on his tombstone.

A short story by mathematician Jacob Bernoulli.

After his death, the Swiss mathematician Jacob Bernoulli, who studied the spiral (known as the thread of life), was engraved on his tombstone with a logarithmic spiral, and the inscription reads: "Although I have changed, I am the same." It's a pun that both portrays the nature of the spiral and symbolizes his love for mathematics.

High fan answer. It's all dry goods, come and pay attention.

Let's talk about following to become the 577th fan.

1. The story of mathematician Chen Jingrun.

Mathematician Chen Jingrun, while thinking about a problem, walked and hit the trunk of a tree without raising his head and said, "I'm sorry, I'm sorry." "Keep thinking.

Test. 2. The story of the mathematician Rudolph.

In the 16th century, the German mathematician Rudolph spent his whole life calculating pi to 35 decimal places, which later generations called Rudolph's number, and he died.

Later, others engraved this number on his tombstone.

3. The short story of the mathematician Jacob Bernoulli.

The Swiss mathematician Jacob Bernoulli, who studied the spiral (known as the thread of life) during his lifetime, had a pair engraved on his tombstone after his death.

Counting the spirals, the inscription reads: "Although I have changed, I am the same". This is a sentence that depicts both the nature of the spiral and the image.

A pun on his love of mathematics.

Hua Luogeng Hua Luogeng loves to use his brain, and often shows a strong interest in some things that seem commonplace to others, and asks some questions that seem strange. Once, when he went to play on the outskirts of the city with others, he saw a stone man and a stone horse beside a deserted grave, and asked his companions, who were older than him, "How many companions do these stone men and stone horses have?"

How can this be known. Hua Luogeng was unwilling, pondered for a moment, and said: There will always be a way to know in the future.

Hua Luogeng's story.

Hua Luogeng was particularly fond of mathematics when he was a teenager, but his math scores were not outstanding. When he was 19 years old, an excellent article alarmed the famous mathematician Xiong Qinglai at the time. Since then, under the guidance of Mr. Xiong Qinglai, he has embarked on the road of studying mathematics.

In his later years, for the sake of the country's economic construction, he popularized and applied pure mathematics to industrial and agricultural production, and struggled for the construction of the motherland for life. The following is an interesting math game that Hua Luogeng's grandfather once introduced to his classmates: there is a teacher who wants to identify which of his three students is smarter.

He used the following method: prepare 3 white hats and 2 black hats in advance, let them see them, then tell them to close their eyes, put their hats on each other, hide the remaining 2 hats, and finally, ask them to open their eyes, look at other people's hats, and say the color of their hats. The three students looked at each other, hesitated for a moment, and said in unison that they were wearing white hats, smart little readers, think about it, how do they know the color of the hat" In order to solve the above problem, let's first consider the problem of "2 people with 1 black hat, 2 white hats".

Because, there is only one black hat, and if I wear it, the other party will immediately say that I am wearing a white hat. But he hesitated for a moment, and it was obvious that I was wearing a white hat.

In this way, the problem of "3 people, 2 black hats, 3 white hats" is easy to solve. Suppose I am wearing a black hat, then the two of them become a "2 people 1 black hat, 2 white hats" problem, they can come out immediately, but they all hesitate for a while, which means that I am wearing a white hat, and the 3 people after the same thinking, so they all deduce that they are wearing white hats. See here.

The students may applaud. Later, Grandpa Hua also complicated the original problem, how to solve the problem of "n people, n-1 black hats, several (no less than n) white hats" can be solved with the same method. He also admonishes us:

To be good at "retreating" complex problems, to "retreat" sufficiently, and to "retreat" to the most primitive place without losing its importance is a trick to learning mathematics well.

Su Buqing: Su Buqing was born in September 1902 in a mountain village in Pingyang County, Zhejiang Province. Although his family is poor, his parents are frugal and work hard to provide for him to go to school. When he was in junior high school, he was not interested in mathematics, and he thought that mathematics was too simple and he could understand it as soon as he learned it.

However, a later math class influenced the course of his life.
