I am really a language teacher

Mathematics, as a scientific discipline, is almost simultaneously in the civilized societies of the East and the West. Both the Sinian people and the Westerners have made outstanding and important contributions to the development of mathematics in their own history.However, with the development of time, natural science has shown a declining trend in the East, but it has flourished in the West.

For this reason, the Aurora National Mathematical Society has always been at odds with the International Mathematical Union. For 50 years, the Aurora National Mathematical Society was independent of the International Mathematical Union.The reason for such an embarrassing situation is nothing more than disputes between the East and the West over the naming of some mathematical laws and the historical positioning of each other's mathematicians.For example, the Pythagorean Theorem of the Cathay Kingdom is called the Pythagorean Theorem in the West. Disputes like this make the mathematicians of the two parties look at each other differently.

But the Aurora mathematicians have to admit that the foundation of modern mathematics was indeed completed by Westerners, and the Aurora people are one step behind in this respect.Although there will be exchanges between the two parties later, sparks fly every time.As a doctoral student in the Department of Mathematics of Southern Institute of Technology, Sun Ping completed the proof of the Poincaré conjecture. Although this paper has been recognized by the Western mathematics community, it does not mean that Sun Ping and Eastern mathematicians have been recognized by them.

When the "Seven Mathematical Problems" were announced, the Aurora Mathematical Society had not yet joined the International Mathematical Union, so this matter had nothing to do with the Aurora Kingdom.However, the proof of one of the conjectures was completed by the people of Cathay.So the American Mathematical Society came to the Southern Institute of Technology to "communicate" this time, which more or less meant that it would come to the gym in the future.

Although the intention of the American Mathematical Society is obvious, the superficial effort is still very good. Several winners of the Pythagoras Award and the Euler Award are on the list of the visiting group.This list not only surprised the technology media, but even the current political news media couldn't help reporting it.The communication between the two parties was quite harmonious in the past few days. Even Sun Ping found it a bit unbelievable. He even thought that Professor Gao called him back to sit in the township. Was it a bit "petty"?

As a result, after most of the official agenda was over, the head of the American Mathematical Society delegation suddenly said: "I am very grateful to the Southern Institute of Technology for taking care of me these few days, and we have also seen the mathematics skills of the undergraduates majoring in mathematics in your country here. But we all know that secondary education is the key to a country’s foundation in mathematics. I wonder if your school is interested in taking us to visit middle schools in your country, so that we can learn about the mathematics education in your country at the middle school stage How is it?"

Although the American Mathematical Society's request was sudden, it was not unreasonable.According to the purpose of the International Mathematical Union, besides being responsible for coordinating and assisting mathematicians in their countries to carry out mathematical research, mathematical societies of various countries also have an important function to promote mathematics education, especially mathematics education in middle school is regarded as the key.Because middle school mathematics education is a stage connecting the past and the future, people will be exposed to the charm of the main categories of mathematics at this stage, such as algebra, geometry, analytic geometry and so on.The excellence of mathematics education at the middle school stage will directly determine the excellence of university mathematics education in the country, so it is not without reason that the American Mathematical Society proposed the inspection intention.

After thinking about it, Professor Gao decided to set the place of visit as Jiangnan Oriental Academy.Professor Gao is not trying to sell face to Sun Ping, but Jiangnan Oriental Academy is not an excellent high school in the traditional sense of Jiangnan Province, but more representative in a general sense; but compared with ordinary high schools, Jiangnan Oriental Academy is obviously It has to be a bit higher, so as not to make the final inspection results too ugly.

Now that Professor Gao has made a decision, someone will rush to notify Jiangnan Oriental Academy.The principal and school managers of Jiangnan Oriental Academy are of course happy to have such a high-level visiting group visit the school. The American Mathematical Society is the leader in the western mathematics field. Being able to visit here is enough to prove that our school is not simple.Since people are here to inspect middle school mathematics education, it is imperative that the academy also inform the teachers of the mathematics teaching and research group to prepare.They are also teachers in the mathematics field. Although they are only middle school teachers, when they see the names of those big professors, these mathematics teachers are as excited as little girls and boys seeing tfboys.

When the mathematics teaching and research group was in full swing, Yu Yili couldn't help snorting coldly: "I really don't know whether I am a Chinese teacher or a math teacher! Isn't your elbow turned outward like this?"

Yu Yili's complaints were heard in the ears of other Chinese teachers, and there were supporters. After all, many people believed that Sun Ping had won this opportunity; What's so sour?What's more, he came to the Mathematics Society. Is it true that our Chinese teaching and research group can receive it?

Just when everyone was full of thoughts, the delegation of the American Mathematical Society, accompanied by the Department of Mathematics of the Southern Institute of Technology, came to the Jiangnan Oriental Academy.American mathematicians are satisfied with the campus environment first, because mathematics is a science that needs inspiration and time, and a quiet environment is very important for mathematicians.The natural design concept of "harmony between man and nature" in the academy also makes mathematicians feel fresh, and the fresh environment is also helpful to stimulate mathematicians' inspiration.

The delegation first went to the classrooms of middle and high schools to see how the mathematics class was taught, and then expressed their desire to give a lecture with a test.The leaders of the academy immediately arranged for the teachers of the mathematics teaching and research group to transfer the top mathematics students from each class to the lecture hall, and then the visiting group also sent a young scholar to give a small lecture to the children.

Needless to say, this young scholar is not only good at Chinese, but also knows how to communicate with children. He explained some cutting-edge and high-end mathematical theories in an easy-to-understand manner.I believe that many of these children will decide to join the ranks of mathematics research because of this lecture.Sun Ping, who was accompanying him, had to admire that this group of Americans had their own way.

Just when everyone thought the lecture was about to end, the young scholar suddenly threw out an allusion.When Sun Ping heard it, isn't this the story of Fermat's last theorem on the earth plane?It's just that in this plane, Fermat's Last Theorem is still called "Tom's Conjecture".When American mathematician Tom Jefferson was reading mathematics classics, he suddenly wrote in his reading notes that when n>2, x^ny^n=z^n has no positive integer solution.When he finished writing this conjecture, he seemed to write another paragraph like a joke, "I am sure I have found a perfect and concise method to prove it".It was this sentence that made mathematicians crazy for more than a hundred years. Although some people thought this conjecture was a prank, many talented mathematicians later proved that this conjecture was partially established in their own ways.

Because of this, this conjecture has become a difficult problem for mathematicians.Some people say that this will be the greatest conjecture in the history of mathematics; others think that this will be the most hateful prank in the history of mathematics.At present, the closest proof of this conjecture is the "ideal prime number" theory of American contemporary female mathematician Joanna. She uses this theory to advance Tom's conjecture a big step forward, and makes more and more mathematicians think that this conjecture may be correct. of.At the same time, because this conjecture does not look complicated, it has become a conjecture often mentioned in many mathematics popularization magazines, so many mathematics enthusiasts who are just getting started are directly directed at this conjecture.

Although the value of this conjecture is not as good as the "Seven Mathematical Problems", the World Congress of Mathematicians also offered a reward of 10 US dollars, hoping that someone can answer it.

When Professor Gao and the others saw that the young scholar brought the topic to this conjecture, their expressions changed, and then the young scholar suddenly said: "Actually, we have explained a lot about 'Tom's conjecture', I wonder if there are any present here Are classmates or teachers interested in proving it?"

"Ridiculous!" Professor Gao quickly stopped.

Any conjecture that has troubled mathematicians for a century is beyond the reach of middle school students and teachers.Although Tom's conjecture seems not difficult, the theory involved in it can only be learned after the university level.In order to reduce the mystery of mathematics, many popular mathematics books often over-promote the role of geniuses in promoting mathematics, while ignoring the contributions of many ordinary people.In fact, as a scientific discipline that develops along with the history of human civilization, its every progress is inseparable from a large amount of accumulation.

Mathematics education in elementary school is only to open the door of mathematics for human beings and cultivate children's interest in mathematics; mathematics education in middle school is to lay the foundation for human beings to study mathematics; only when you go to university can you really touch the essence of mathematics.But if you want to study mathematics, at least you dare to say it after you graduate with a Ph.D.Now throwing such a difficult problem, how many people have lost interest and confidence in mathematics because they are tortured by difficult mathematics.

If someone came from a formal mathematics class, Professor Gao might not say anything, after all, he would know how to regulate himself.But the vast majority of the people sitting here are still children who have just developed a great interest in mathematics. It can be said that they are good seedlings in the future of the mathematics field in Cathay. The move of the American Mathematical Society is like spraying pesticides on this fertile land He intends to destroy this group of children.

But at this time the leader of the Mathematics Society stood up, "Professor Gao, we are just throwing bricks to attract ideas. If you can't do it or don't want to do it, then don't do it. In our United States, this question is one of the sat math test questions." one."

Since Professor Gao had never been in contact with the American SAT test, he was choked up.But Sun Ping immediately recalled the SAT math test papers in the United States over the years. In the test papers of the past 20 years, "Tom's Conjecture" was hardly mentioned. It was only mentioned in the math test papers of 37 years. Instead, let students guess the correctness of the conjecture based on their own understanding of mathematics.This question is a subjective question, and it does not stipulate that the answer must be right or wrong. It basically examines students' understanding of mathematics and sorting out existing knowledge.Even so, this question has been criticized for a long time, and later there is no such question in the SAT test.

So Sun Ping immediately opened his mouth to refute the nonsense of the Americans, especially after Sun Ping pointed out the real intention of the question at that time, the faces of several American professors were a little ugly.Finally, Sun Ping added, "Is it just a 'Tom's conjecture'? Although I may not be able to restore Mr. Tom Jefferson's proof back then, it is not difficult to prove its correctness. Otherwise, I will be a It’s enough to prove it in front of everyone.”

Sun Ping stepped onto the podium, picked up the pressure-sensitive pen, and started writing on the screen on the podium.At this time, the blackboard is displayed synchronously, and smart devices that can be connected to the lecture theater and have installed the corresponding software of the Oriental Academy can also view it online.
