The fact that Gauss was able to correct his father's debt accounts at the age of 3 has become an anecdote that has survived to this day. He once said that he learned to calculate on the Mai Xian Ong pile. Being able to make complex calculations in his head was a gift from God that he had given him a lifetime.
When Gauss was 9 years old, Gauss spent a very short time calculating the task assigned by his elementary school teacher: summing natural numbers from 1 to 100. The method he used was:
The sum of 50 pairs of numbers constructed into a sum of 101 is (1+100, 2+99, 3+98......).At the same time, the result is obtained: 5050. However, according to more elaborate mathematical history books, Gauss's solution is not as simple as adding 1 to 100, but 81297+81495+...
100899 (tolerance 198, number of terms 100).
By the time Gauss was 12 years old, he had already begun to doubt the fundamental proofs in elemental geometry. When he was 16 years old, a completely different geometry would inevitably arise outside of Euclidean geometry. He derived the general form of the binomial theorem, successfully applied it to infinite series, and developed the theory of mathematical analysis.
Gauss's teacher Bruettner and his assistant Martin Bartels recognized Gauss's extraordinary talent for mathematics at an early age, and Herzog Carl Wilhelm Ferdinand von Braunschweig was impressed by the gifted child. So they sponsored Gauss's studies and life from the age of 14. This also allowed Gauss to study at the Carolinum Academy (the predecessor of today's Braunschweig College) in 1792-1795 AD.
At the age of 18, Gauss transferred to the University of Göttingen. At the age of 19, he was the first to succeed in constructing a regular 17-angle shape with a ruler.

Mathematical magician.
One summer day in 1981, a mental arithmetic competition was held in India. The performer is a 37-year-old woman from India whose name is Shaguntana. On that day, she had to compete with an advanced electronic computer with amazing mental arithmetic skills.
The staff writes a large number of 201 digits and asks you to find the 23rd root of the number. As a result, it took only 50 seconds for Shaguntana to report the correct answer to the audience. In order to arrive at the same number of answers, the computer has to input 20,000 instructions and then calculate them, which takes much more time than Shagontana.
This anecdote caused an international sensation, and Shagontana was called the "mathematical magician".

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.

Hua Luogeng is a master of modern mathematics plagiarism, too.
He is a man of learning. In the early 50s, the Chinese Academy of Sciences organized 16 famous scientists such as Qian Sanqiang, Zhao Jiuzhang and Hua Luogeng to go abroad. On the way, scientists talk about the past and the present.
Hua Luogeng took Qian Sanqiang as the title, and casually put out a couplet: Han Zhaowei, the top three, and consulted the next couplet. Everyone looked at each other, pondered and meditated, and could not be right.
Finally, Hua Luogeng pointed to Zhao Jiuzhang beside him and said: Chapter 9 Pythagorean strings. Hua Luogeng is familiar with the history of mathematics, and he has become a wonderful pair at his fingertips.
Su Buqing was born in September 1902 in Zhejiang Province. When I was in my third year of junior high school, a math teacher came. He said:
In today's world, the world's great powers want to carve up China. The danger of China's demise is imminent. 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. At the age of 17, Su Buqing went to Japan to study. When he went to become an associate professor at a university in Japan, Su Buqing decided to return to China.

Carl Fle.
Riedrrich Yuan Gauss (born in Braunschweig and died in Göttingen) was a German mathematician, physicist and astronomer, geodesy. One of the founders of modern mathematics, he has a great influence in history, and can be ranked alongside Archimedes, Newton, and Euler, and is known as the "Prince of Mathematics".
-*****== Here's one of the stories about him ********************=
In a very short time, Gauss calculated the task assigned by the elementary school teacher: to sum the natural numbers from 1 to 100. The method he used was:
Sum 50 pairs of numbers constructed into a sum of 101 (1+100, 2+99, 3+98......).At the same time, the result is obtained: 5050. This year, Gauss was 9 years old.

Hua Luogeng's story.
In 1946, Hua Luogeng was invited to give lectures in the United States, and was hired as a tenured professor by the University of Illinois with a high salary. At that time, many people thought that Hua Luogeng would not come back. The birth of New China touched the heart of Hua Luogeng, who loved the motherland.
In 1950, he resolutely gave up his affluent life in the United States and returned to his motherland, and wrote an open letter to Chinese students studying in the United States, mobilizing them to return to China to participate in socialist construction. In his letter, he revealed a pure heart of love for China:"Friends!
Although Liang Yuan is good, it is not a long-term hometown. It's ...... to returnFor the sake of the country and the nation, we should go back to ......"Although mathematics knows no borders, mathematicians have their own homeland.
Gauss Jr. spent one night making a regular 17-sided shape that had not been solved for more than 2,000 years. When the teacher asked Gauss how he did it, he said, "If I had known that this was a puzzle that had not been solved for more than 2,000 years, I would not have had the confidence to do it." ”

The Story of a Scientist Hua Luogeng.
On November 12, 1910, Hua Luogeng was born in Jintan County, Jiangsu Province. His family was poor and determined to study hard. When I was in middle school, in a math class, the teacher gave my classmates a famous problem:
There is a number, 3 3 numbers of 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 stood up and said, "23" His answer surprised the teacher and was praised by the teacher.
From then on, he fell in love with mathematics.
For the sake of an internationally renowned number of my country, once, a woman went to buy cotton, Hua Luogeng was calculating a math problem, and the woman said how much cotton she wanted? However, the diligent Hua Luogeng didn't hear it, so he answered the answer to the calculation, and the woman screamed: "Why is it so expensive? At this time, Hua Luogeng knew that someone had come to buy cotton, so he said**, and the woman bought a bag of cotton and left. Hua Luogeng was about to sit down and continue to count, only to find that the straw paper that had just calculated the topic was taken away by the woman.
This can be a big deal for Hua Luogeng, so desperate to chase, a yellow bag master saw the internationally renowned modern mathematician Professor Hua Luogeng.
So he let him take the car (because they knew each other), and finally caught up, Hua Luogeng said embarrassedly: "Auntie, please ......."Please give me back the straw paper", and the woman said angrily, "I paid for it, not you".
Hua Luogeng was in a hurry, so he said: "Otherwise! I paid for it."
When Hua Luogeng reached out to take out the money, the woman seemed to be moved by this child! Not only did he not ask for money, but he also returned the straw paper to Hua Luogeng. At this time, Hua Luogeng was slightly relieved, and after returning home, he calculated ......

One day, the French mathematician Pu Feng invited many friends to his home and did an experiment. Pu Feng laid out a large white paper on the table, and the white paper was full of parallel lines at equal distances, and he took out many small needles of equal length, and the length of the small needles was half the length of the parallel lines. Pu Feng said:
Please put these little needles on this blank piece of paper and feel free to do so! The guests did as he was told.
This number is an approximation of . An approximation of pi is obtained each time, and the more times you throw, the more accurate the approximation of pi will be. This is known as the "Pufeng Experiment".

Mathematician Hua Luogeng is not only willing to work hard, but also good at using his brains in his studies. When he was 14 years old, he once gave his classmates such a question in class: "I don't know how many things are today, there are two left, three or five numbers are left, and seven or seven numbers are left.
This title comes from the ancient "Sun Tzu Sutra", which means: There is a kind of thing, I don't know the number, if you count it in three or three, there will be two left in the end; Count it five by five, and at last there are three left; Seven and seven to count it, and at last there were two left. Ask how many of these things there are.
As soon as Mr. Wang finished reading the question, Hua Luogeng's answer blurted out: "Twenty-three!" ”
Why, have you read "Sun Tzu's Sutra"? Teacher Wang asked in surprise.
Hua Luogeng said: "I don't know the book "Sun Tzu's Calculations", let alone read it. ”
So how did you figure it out? Teacher Wang asked again.
Hua Luogeng replied with a clear eye: "I think so, three three places, the remaining two, seven seven places, the remaining two, and the remainder are all two, then, the total number may be three times seven plus two, equal to twenty-three, twenty-three is removed by five, and the remainder is exactly three, so twenty-three is the number sought." ”
Ah-" Teacher Wang was simply stunned, "Clever calculation, clever calculation!" ”
The great mathematician of the Northern and Southern Dynasties, Zu Chongzhi, calculated pi to the seventh decimal place. It is proved that pi is located between and . More than a thousand years before the Europeans got the same result.
The Pythagoreans of ancient Greece believed that any number in the world could be expressed as an integer or a fraction, and made this one of their creeds. One day, one of the members of this school, Hippasus, suddenly discovered that the diagonal of a square with a side length of 1 was a strange number, and he studied it diligently, and finally proved that it could not be represented by integers or fractions. But this broke the tenets of the Pythagoreans, and Pythagoras ordered him not to spread the word. >>>More
