Gauss: When the mathematician Gauss was in high school, the teacher would give him two difficult problems for him to practice, but he basically solved them quickly, and he gave a problem one day, and he took a night to make it, and then when he came to the school and asked the teacher, it was a mathematical problem in the world, which has plagued mathematicians for many years.

With the rapid development of economic globalization and the progress of science and technology, people have higher requirements for experimental teaching in the cultivation of innovative talents, so in order to meet the needs of social development, it is necessary to pay attention to the reform of experimental teaching. Experimental teaching is an important part of the quality and ability training of college students, and the establishment of a new experimental teaching system can further improve the quality of experimental teaching.
In order to improve the quality of experimental teaching, it is necessary to establish a complete experimental teaching system, build a suitable experimental teaching platform, and create a good experimental teaching environment. Therefore, it is necessary to strengthen the construction of the experimental teaching team, improve the theoretical guidance level of experimental technicians, guide students to experiment around the clock, promote the communication between students and teachers, encourage students to participate in teachers' scientific research work, strengthen students' scientific research ability and practical ability training, and make the laboratory a relatively independent teaching entity.
At the same time, due to time constraints, it is difficult to synchronize theoretical courses and experimental courses, so it is necessary to establish an information-based experimental teaching platform based on modern computer and network technology, establish an experimental teaching system for students' independent learning, provide rich network experimental teaching resources, and realize online auxiliary teaching and networked and intelligent management. Students can browse the relevant theoretical knowledge and the teacher's lectures online, and they can also ask questions online, and the teacher can answer questions online, so as to realize the network interaction and resource sharing between teachers and students, and meet the basic needs of the current professional teaching. The new educational concept also requires teachers to have the courage to explore teaching methods and keep up with the pace of computer development, so as to promote education and teaching to a new level.

1. When Gauss was at the University of Göttingen, he was late for some reason, and when he arrived at the classroom, the teacher was not there, and there were only a few questions on the blackboard. He thought it was homework and pondered it all night, but he only solved one problem. When I handed it to the teacher, the teacher said that these are the most famous problems in the history of mathematics!
Gauss was only 19 years old at the time.
2. Chen Jingrun is a famous mathematician in my country, once he felt that his hair was long and went to get a haircut, and when he saw that the number was 38, he felt that there was still time, so he hurried up to start studying, and even went to the library to consult the information, and when the number was called to him, he was still reading in the library and forgetting all about the haircut.
3. Hua Luogeng's family was poor when he was young, and when he was in middle school mathematics class, the teacher gave the students a famous problem: "There is a number, 3 3 numbers in 3 places, and there are 2 left; 5 5 land numbers, 3 remaining; 7 7 7 places, there are 2 left, what is the number of this? While everyone was thinking, Hua Luogeng had already said the answer "23", and it was from then on that he fell in love with mathematics.
4, Gauss's math teacher asked everyone to calculate the sum from 1 plus 2 plus 3 to 100, and Gauss Jr. worked out the answer in half an hour, and his method was used by the ancient Greeks and Chinese to calculate the series 1+2+3+....+n. The teacher liked the child very much, and often bought some math books from the city to study and lend them to Gauss, and it was from then that Gauss began to study mathematics.
5. Su Buqing didn't like mathematics before, in the third year of junior high school, a teacher who returned from studying in Japan told about the huge role of mathematics in the development of modern science and technology, which touched him deeply, and from then on Su Buqing's interest shifted from literature to mathematics, and set up the motto of "don't forget to save the country by reading, and don't forget to read to save the country". When he graduated from middle school, Su Buqing's homework was above 90 points.

Gauss was born poor, loved mathematics from an early age, corrected his father's calculation mistakes, and grew up to become the most prominent astronomer and mathematician of our time.
The great mathematician Archimedes identified the crown for King Syhaielo and was inspired to use the drainage method to determine whether the crown was adulterated.
The mathematician Rudolph calculated pi to 35 decimal places, which was called Rudolph's number, and after his death, others engraved the number on his tombstone.
Liu Hui of the Eastern Han Dynasty was the first person in the world to put forward the concept of decimal decimal numbers, and used decimal decimal numbers to represent the cube root of irrational numbers, making great contributions to the development of mathematics.
When he was a child, the Swiss mathematician and physicist Euler was expelled from school because he asked his teacher how many stars there were, which angered the teacher's creed, and ended up being a shepherd boy.

The answer is to see him come; Buicman, in particular, was surprised that all the young French soldier's answers were not wrong at all. As a result, the two became good friends, and Descartes became a frequent visitor to the Buicman house.

1. The Swiss mathematician Jacob Bernoulli, who studied the spiral (known as the line of life) before his death, after his death, a logarithmic spiral was engraved on the tombstone, and the inscription also read: "Although I have changed, I am the same."
2. Mathematics Chen Jingrun's short story: Chen Jingrun was walking while thinking about a problem, and hit a tree trunk without raising his head and said, "I'm sorry, I'm sorry." "Keep thinking.
3. 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 was called the Rudolph number by later generations, and others engraved this number on his tombstone after his death.
5. The ancient Greek scholar Archimedes died at the hands of the Roman enemy soldiers who attacked Sicily, and before he died, he was still praying: "Don't break my circle".
6. Eight-year-old Gauss discovered the mathematical theorem, which was used by the Greeks and Chinese in ancient times to calculate the series 1+2+3+....+n.
7. Von Neumann, the electronic computer invented in 1946, is praised by Westerners"The father of the computer"。Under the individual guidance of Mr. Fickert and co-authored the first math article**, von Neumann was not yet 18 years old.
8. Galois, in 1823, at the age of 12, Galois left his parents to study in Paris, and went to find the most difficult mathematical original works to study, and the teachers commented that he was "only suitable to work in the cutting-edge field of mathematics".
9. Zu Chongzhi's outstanding achievement in mathematics is about the calculation of pi. Before the Qin and Han dynasties, people to:"Trail three times a week"As pi, this is"Ancient rate"。
10. Cyles, the first world-famous mathematician in ancient Greece. In Egypt, Seles learned about the rich mathematical knowledge that the ancient Egyptians had accumulated over thousands of years.

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 answer was, "What is the point of enduring hardship, I am willing, because I have chosen a correct path, which is a patriotic and bright road!" ”
This is the patriotic heart of the mathematicians of the older generation.
