"Have you really decided? Take the college entrance examination this year?" Feng Lin was a little puzzled: "You can go to any university you want, why do you still need to take the college entrance examination? Isn't this a waste of time?"

"And you just said you were going to participate in the second round of training in the middle of the year. Once you enter the Chinese national team, you will have to receive training in the capital. Isn't it very time-consuming to take the college entrance examination?" Feng Lin frowned slightly.

She felt that what Liu Yichen did was undoubtedly superfluous and unnecessary.

The purpose of the college entrance examination is not to get into a prestigious school. Nowadays, the major schools have opened their arms and let Liu Yichen choose. Just like the emperor's draft in ancient times, it all depends on where Liu Yichen goes and which one he chooses.

The result was good, Liu Yichen actually wanted to take the college entrance examination this year. Isn't this because he had enough to eat and had nothing to do?

According to her understanding, Liu Yichen should focus all his energy on the mathematics competition and strive to be included in the six-man Chinese national team roster in the second round of training, represent China in the International Olympiad Mathematics Competition, and win honors for the country.

This imo gold medal is no less valuable than an Olympic gold medal, or even higher than that.

Winning the IMO gold medal is bringing glory to the country, but taking the college entrance examination, even if you reach the admission score of Qingbei University, so what? How can it compare with such a major event as bringing glory to the country, such as the IMO gold medal.

"Don't you want to have a boyfriend who is the number one scholar in the province?" Liu Yichen said with a smile.

Feng Lin couldn't help but blush.

Liu Yichen did not tease Feng Lin, and said: "Don't worry, you don't have to choose one of the two, you can do both at the same time."

Yes, in Liu Yichen's view, this is not contradictory at all.

"Okay, you are awesome~~" Feng Lin said.

At the beginning of the new semester, the pressure has gone up to a higher level than in the previous semester. Feng Lin is even more envious of Liu Yichen, who has no pressure at all.

"Eat more. This soup can reduce inflammation and clear away toxins. It is most suitable for you now!" Liu Yichen served Feng Lin a bowl of soup and said.

We haven't seen each other for a while, and Feng Lin's hair looks a little rough. It's obvious that she is under too much pressure. Although Feng Lin studies seriously, she is still around 30 in her year and can never make it up.

After all, she was making progress, and so were others. By this time, it was almost finalized.

Unless Feng Lin suddenly gets through her nerves, becomes enlightened, and becomes a completely different person, otherwise there is basically no hope for her to be ranked in the top 20.

Therefore, hard work in studying is important, but talent is also important. Even to a certain extent, talent is more important, because talent represents the ceiling, the upper limit. The higher the talent, the higher your upper limit. And if the talent is average, the upper limit is

There, the average 985 is the upper limit for people with average talent. No matter how hard you try, it will be difficult to exceed this upper limit.

This is why if you want to go to Qingbei University, in addition to hard work, you also need to be very talented!

As Liu Yichen decided to take the college entrance examination in June this year, he became even busier, because he had to take the college entrance examination and pass the three subjects of history, geography, and politics. He also had to take computer classes, music classes, and art classes.

There are physical exams. Although these exams are actually not important, the procedures are like this. You have to go through the procedures one by one. Only then will there be no problems with the procedures and will not leave any excuses for others and be used to make excuses.

After filling out the college entrance examination registration form, Liu Yichen had to embark on his second round of training. This time the second round of training was from March 15th to March 23rd.

Compared with the 100 math contestants in the first round of training, there are only 19 this time. The list of 19 people will be competed in the second round of training, and 6 places will eventually be competed to form the Chinese national team.

Slightly different from the first round of training, the second round of training is more intensive and more intense. For example, in the plane geometry part, a mathematics professor from Kyungseong University started training through 21 questions, analyzing and solving them.

The ideas contain skills and the knowledge involved, and sometimes even university knowledge is used to answer the questions.

The 21 questions are taught directly from morning to 9:00 in the evening. The intensity is not low. During the explanation process, you may not understand something or you may not understand something, but you cannot interrupt the teacher's lecture.

, if you don’t understand, you can study harder by yourself at night, ask someone who understands, or pick up the textbook and read it.

And this is just plane geometry, there are also training courses in number theory, solid geometry, algebra, combination, etc.

If ordinary high school students are to read it, it will definitely be like listening to a wordless bible, because the difficulty is beyond the ability of ordinary high school students to understand. Even most college seniors will be confused when listening to it.

Water is not allowed.

Why Mizuki and Yanda are fighting so hard for these students is because these students have surpassed most college students in high school. This is due to their solid basic mathematics skills. As long as they enter college and train well, they will be extremely good.

of college students.

Liu Yichen also secretly lamented that the level of the training teachers in this second round of training is indeed far from that of high school mathematics teachers. High school mathematics teachers may be able to give you questions from the mathematics league, but they cannot explain it to you in such an in-depth and simple way.

The level of both parties is not at the same level at all.

The reason why a high school mathematics teacher is a high school mathematics teacher is because he is only oriented to the high school level. He has become accustomed to the knowledge of the high school level and it is difficult to expand it wider and wider. University mathematics professors are different.

Their research on mathematics is deeper, and he can explain the essence of mathematics more closely than a high school teacher.

Of course, the lectures given by these university professors are not without drawbacks, that is, they are not very detailed. Many of them are just a quick summary. Whether you can understand it or not, whether you can understand it or not, depends on you.

For example, there is often more than one solution to a question. In the past, you may only be exposed to one solution, but now you may be exposed to the second solution, or even the third solution.

In fact, having too many solutions is sometimes not a good thing, because it will lead to more needs to be understood and more knowledge points to be mastered, which will lead to confusion of knowledge points.

"Liu Yichen, can you help me with this question?" Wei Dongyi came over shyly, touched his head, and said with some embarrassment.

"Let me see!" Liu Yichen looked at the question: "Suppose abcd is a trapezoid, ab∥cd, and there are points p and q on its two drugs ad and bc, such that ∠apb=∠cpd, ∠aqb=∠cqd,

Prove that the distances from points p and q to the intersection of the two diagonals of the trapezoid are equal."

After reading the question, Liu Yichen had already drawn the corresponding figure on the draft paper and marked the corresponding corners. Then in this figure, Liu Yichen made an auxiliary circle, and the circumcircle of △apb and △cpd intersects at point q1, and the circumscribed circle

The radius of the circle are r1, r2....

"You see, from here we can see that o is on o1o2, and o1o2 is the mid-perpendicular of pq, so we have op=oq!" Liu Yichen said.

"I understand, thank you!" Wei Dongyi grinned and left.

Liu Yichen smiled. In fact, Wei Dongyi seemed better if he didn't smile. This smile immediately dropped a level.

However, everyone relies on their talent to make a living, not their face, which is just a piece of shit.

Isn’t there a saying that says, good-looking skins are all the same, but interesting souls are only one in a million!

However, Liu Yichen has to admit that Wei Dongyi's talent is indeed good. During the CMO competition, Wei Dongyi was ranked 11th, but his current performance is almost 6th, and he has hope of entering the Chinese national team.

Of course, the specific details will depend on the final score, which will not be announced until the last day by team leader Xiong Bin.

"The reply from the "Journal of Symbolic Logic" was really polite... I just don't know when it will complete the review and when it will be able to publish the paper." In the evening, Liu Yichen opened his laptop, entered his mailbox, and saw

When I received the reply from the "Journal of Symbolic Logic", I couldn't help but murmur to myself.

Of course, whether people are willing to include it or not is also a question.

Looking at the forum again, one topic was very noisy at this time, that is, Qiu Chengtong announced: "Cao Huaidong and Zhu Xiping have completed the capstone of the Poincaré conjecture!" This caused a lot of controversy.

For example, Ding Weiyue made another voice: "The common international view is that the mathematician Perelman has given a complete proof of the Poincaré conjecture." "This kind of mistake in the domestic media has a major relationship with him." "Now,

There are doubts about whether Cao Huaidong and Zhu Xiping’s articles have gone through the normal review process.”

Because the people involved are all famous mathematicians, needless to say, Qiu Chengtong, Cao Huaidong is a chair professor of the Department of Mathematics at Lehigh University in the United States and a lecturer at Shumu University. He is engaged in differential geometry and nonlinear partial differential equations, involving kahler-i flow.

, mathematical physics is quite famous. Zhu Xiping is a professor of the Department of Mathematics at Sun Yat-sen University. In 2004, he won the Morningside Mathematics Silver Medal from the World Congress of Chinese Mathematicians. He has long been conducting research in the field of geometric analysis in core mathematics at the international forefront.

Cao Huaidong and Zhu Xiping have a common identity, that is, they are Qiu Chengtong's students!

As for Ding Weiyue, he is no ordinary person. His research fields include ordinary differential equations, semilinear elliptic equations, harmonic mapping and minimal surfaces, predetermined quantity curvature problems, Schrodinger flow, the existence of Kahler-Einstein measures in complex geometry, etc. He is

He is a professor in the Department of Mathematics at Yanda University, a doctoral supervisor, and an academician of the Chinese Academy of Sciences.

Therefore, this was extended to the continuation of the academic dispute between Qiu and Tian, ​​and once again set off a major discussion of grievances between Qiu and the Department of Mathematics at Yanda.

Now Liu Yichen is just a newbie. He can't understand their papers, and he can't tell who is right and who is wrong on both sides, so he never participates in the discussion. In his opinion, this kind of debate is just in the history of mathematics.

It's just a trivial little splash. Think about the debate between Newton and Leibniz. It took 300 years for the dispute to come out.
Chapter completed!
