The story of the mathematician 1 is good, the story of the mathematician is complete

In 1785, at the age of 8, Gauss was in the first grade in an elementary school in rural Germany.

One day, the teacher came up with an arithmetic problem. He said, "Do the math, 1 plus 2 plus 3, all the way up to 100 is what is the amount?"

Whoever can't figure it out is not allowed to go home for dinner. In less than a minute, little Gauss stood up, holding the small slate in his hand, and said, "Teacher, I have figured it out."

Before Gauss could finish speaking, the teacher said impatiently, "No! Recount! ”

Little Gauss quickly checked it and said loudly, "Teacher, that's right! As he spoke, he stepped out of his seat and stretched the small slate in front of the teacher.

When the teacher saw that it read "5050" on it, he couldn't help but be surprised. He couldn't believe that an 8-year-old child could figure out the correct number in less than a minute for such a complex math problem. You know, it took him more than an hour to calculate this problem correctly.

He suspected that someone else had asked Gauss Jr. to do the math before. Just asked, "How do you calculate?"

Little Gauss said, "Teacher, you see, the sum of the two numbers at the beginning and the end is the same: 1 plus 100 is 101, 2 plus 99 is 101, 3 plus 98 is also 101....

Add the numbers one after the other, there are 50 101s, and multiply 101 by 50 to get 5050. ”

Little Gauss surprised the teacher. Because this is the first time he has known about this algorithm. He looked at little Gauss in surprise, as if he had just met this student.

Soon after, the teacher bought a math book for little Gauss, and recommended Gauss to the education authorities, so that he could get free education. Later, Gauss Jr. became a world-famous mathematician.

Then it depends on you to see it in your space as soon as possible, you see it, you see it, you see it, you see it

The story of a mathematician - 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, thinking that mathematics was too simple and he could understand it as soon as he learned it.

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

It was when Su Buqing was in his third year of junior high school, and he was studying in Zhejiang Province No. 60 Middle School, and there was a teacher Yang who had just returned from studying in Tokyo to teach mathematics. In the first class, Mr. Yang did not talk about mathematics, but told stories. He said:

In today's world, the law of the jungle eats the strong, and the world's great powers rely on the strength of their ships and guns to carve up China. The danger of China's extinction is imminent, and it is a move to revitalize science, develop industry, and save the country. 'The rise and fall of the world is the responsibility of the husband', and every student here has a responsibility.

He talked about the great role of mathematics in the development of modern science and technology. The last sentence of the lesson was: "In order to save the world, science must be revitalized."

Mathematics is the pioneer of science, and in order to develop science, it is necessary to learn mathematics well. Su Buqing didn't know how many classes he had heard in his life, but this class made him unforgettable for life.

Mr. Yang's class deeply touched him and injected new stimulants into his mind. Studying, not only to get rid of personal difficulties, but also to save the vast number of suffering people in China; Studying is not only to find a way out for individuals, but also to seek a new life for the Chinese nation. That night, Su Buqing tossed and turned, unable to sleep all night.

Under the influence of Mr. Yang, Su Buqing's interest shifted from literature to mathematics, and since then he has set up the motto of "reading without forgetting to save the country, and saving the country without forgetting to read". As soon as he became obsessed with mathematics, whether it was a scorching summer or midwinter, a frosty morning or a snowy night, Su Buqing only knew how to read, think, solve problems, and calculate, and he calculated tens of thousands of number learning problems in 4 years. Now Wenzhou No. 1 Middle School (that is, the Provincial No. 10 Middle School at that time) still treasures Su Buqing's geometry exercise book, which is written with a brush and is neat.

When he graduated from middle school, Su Buqing's homework was above 90 points.

At the age of 17, Su Buqing went to Japan to study and was admitted to the Tokyo Higher Technical School with the first place, where he studied hungrily. The belief in winning glory for the country drove Su Buqing to enter the field of mathematics research earlier, and while completing his studies, he wrote more than 30 articles**, achieved remarkable results in differential geometry, and obtained a doctorate in science in 1931. Before receiving his Ph.D., Su Buqing was already a lecturer in the Department of Mathematics at Imperial University of Japan, but just as a Japanese university was about to hire him as an associate professor with a good salary, Su Buqing decided to return to China and return to his ancestors who raised him to teach.

Su Buqing, who returned to Zhejiang University as a professor, lived a very difficult life. In the face of the predicament, Su Buqing's "What is the benefit of hardship, I am willing, because I have chosen a correct path, which is a bright road of patriotism!" ”

This is the patriotic heart of the older generation of mathematicians.

Hua Luogeng was studious, and when he was in junior high school, he showed a special talent in arithmetic class. One day, Teacher Wang Wei gave the class an arithmetic problem, which was a title question from "Sun Tzu'er Sutra": "At present, there are things that do not know the number, three or three are left, five or five are left, and seven or seven are left, and the geometry of things is asked?"

When Instructor Wang read this question, he read it very slowly, and his voice was frustrating. After reading the title question, Instructor Wang swept his eyes to the whole class, and the faces of nervous thinking and puzzled eyes were all within Instructor Wang's field of vision. Oh, a student stood up and said:

This item is 2 three. It was a familiar sound, and it woke the students from their thoughts and doubts. And they looked at him with astonishment.

The first classmate to say the answer was the teenager Hua Luogeng. Hua Luogeng thought as he wished when solving this problem: starting from "the remaining two of the seven and seven numbers", that is, the seven numbers are more than two, and the multiple of the last seven plus two must be this number, and the number is 7 3 2 = 23.

Then check 23: 23 is divided by 3, and the remaining 2; 23 is divided by 5 by 3, therefore, 23 qualifies as a title question. It is precisely because Hua Luogeng has been diligent and studious since he was a child that Teacher Wang Wei redoubled his admiration for his intelligence and talent.

Hua Luogeng left a deep impression on Teacher Wang when he was in the dormitory.

I bought a dress with a price tag of 50 (cost of 30) and gave the boss 100 (fake banknotes) The boss looked for him for 50, and the next day Xiao Ming took the clothes +20 and changed to a dress with a price of 70 (cost of 50). Q: How much money did the boss lose?

For the boss, the first day loses 30 + 50 = 80

The next day, 30 + 20-50 = 0

So the boss still pays 80 yuan.

Hua Luogeng, a famous mathematician in China, only studied in junior high school and never went to college at all. Its success depends on diligence and assiduous self-study. Because of his family's poverty, he dropped out of junior high school and started a business in his family's small grocery store, selling cigarettes and needlework.

However, mathematics still can't be put down. Almost every day of the year, I spend more than a dozen hours studying mathematics. Even though he later contracted typhoid fever and had a lifelong disability in his left foot, he did not stop studying mathematics because of the illness.

With unremitting diligence, he finally became a world-famous mathematician.
