Chapter 26 Solving the World's Three Major Mathematical Problems
Yang Fan was ready to wait in the corridor, and the next second test would start in twenty minutes.
The students looked for their own acquaintances to answer the questions, some sighed, some were full of confidence, and all kinds of expressions.
At this time, Feng Yao came over with four disciples. The faces of the four of them were extremely ugly, and Feng Yao also had a gloomy face.
"Yang Fan, how did you do in the exam?" Feng Yao asked with concern.
"It's okay, the amount of calculation is relatively large, and the difficulty is medium to high. ”
"Oh, since that's the ......case," Feng Yao hesitated, and finally made up his mind and took out a scroll, "If you are confident, see the answer." I also made the roll just now, you can compare it. ”
The four disciples had already been hit just now, and Feng Yao was afraid that Yang Fan would not be able to accept the result, so he was a little hesitant. Now that he is full of confidence, he still decided to let him be right.
Yang Fan compared Feng Yao's answer with his own, and one was correct. He didn't want to be too exaggerated, and said, "Teacher Feng, in the last question, I omitted two steps, I don't know if I will deduct points." ”
Feng Yao was stunned for a moment, suppressed his surprise, and pretended to be gloomy and said: "Yang Fan, I also just received the news, this topic is from Ge Jun, are you sure that only the last question has questions?"
Who is Ge Jun? Millions of candidates who have understood the difficulty of his questions have absolutely hacked him for the rest of his life. Receiving the news at that time, Feng Yao was ready. Sure enough, Ge Jun is a pervert.
The difficulty of these questions is indeed medium to high, but it pays attention to divergent thinking, and the amount of calculation is very large, and it is not enough time to complete it from beginning to end.
"Yang Fan, are you done? I didn't have time to write the last two questions. It's over, it's over, I didn't expect to run into him, it's really late. Cui Qiming gritted his teeth and scolded.
Ye Haoran stretched out a finger, it seems that there is a question that he didn't have to do in a hurry. For the other two, the gap is even greater.
Yang Fan would never say that he completed it the first time, took thirty minutes, checked it two or three times, and was bored to figure out the questioner's thoughts.
"For the last question, even if you omit the steps, the answer is accurate, and a few points will be deducted at most. So, Yang Fan, are you sure that it is above 115?" Feng Yao asked again.
"Almost. Yang Fan muttered in his heart, "Teacher Feng, the steps of your last question are cumbersome, it's not that I'm less, it's you who are more." ”
"It's not bad, the end continues, and you guys have to work hard. Now that it's over, relax. Remember, as long as you have a total score of 300 points in two rounds, you can get a third-class general, and you have to grasp the back. ”
The five people left, Yang Fan was stunned, he even underestimated himself, to have confidence, this time, he really felt that the so-called science genius, the so-called first in the grade, could only see his back.
The second round of exams begins, and the papers are distributed. The test questions are four answer questions, the first two questions are 40 points each, and the last two questions are 50 points each, with a full score of 180 points, and the test time is 2 and a half hours.
As you can see from the time, the difficulty of the second round, four questions, takes 150 minutes.
Normally, it is definitely from easy to difficult, and the time is still early, Yang Fan decided to try it himself to see how far he can go.
The first course, it took five minutes to clear my thoughts, and I calculated while doing it, and the time for checking and completing the calculation was exactly twenty minutes.
Yang Fan was shocked, a little interesting, the first question took so long. Looking up, most of the students were biting their noses and frowning in a daze.
In the second round, most of the students were made of soy sauce. Continuing to tackle the second question, the difficulty has risen steadily, and the amount of calculation has increased.
Fortunately, I have a clear mind and can do it. It took half an hour to finally finish.
The third question, halfway through, can't be carried out anyway. The steps are not bad, the conditions are clearly explained, but a little bit of sparkle is missing.
Yang Fan rubbed for ten minutes and estimated his total score, even if he didn't do it now, he would have more than 200 points, and he couldn't escape the second prize.
Do you want to continue? If you do it yourself, it's still an endless loop, and time is running out.
Faith wars, or decides to forgive yourself for a small means. First, this topic is very interesting, Yang Fan is sure that if he doesn't solve it now, he will not sleep well for a few days and nights, and hate his stupidity.
Second, I will definitely detach myself in the future and leave those people behind, and now, it is not impossible to use my potential in advance. There is also a benefit, the spirit can be infected, and the bearing of those masters will give feedback.
Chen Jingrun possessed. ”
The whole person was not shaken, the topic was swept away, and the fog was seen through one by one. Yang Fan's pen is like a divine help.
The last question and a half took a total of fifteen minutes, mainly because of the huge amount of calculations and extremely tedious.
The train of thought kept up with the handwriting, without the slightest pause, hearty. Yang Fan put down his pen and recalculated, why he couldn't think of it at that time, and the master could be so easy.
This imitation, Yang Fan found that his own background is not enough, the second round, is out of the syllabus, the last two questions, if it is a senior high school student, can only solve some leftovers. If you want to be able to do it, at least to the level of a sophomore.
The master possessed him, re-checked, and it took ten minutes, Yang Fan was satisfied, and it should be another full score. The second time, you don't have to try it.
Looking at the time, there are still forty minutes. I can't hand in the papers, do something.
I don't know where I got the idea, so he asked the invigilator for a piece of scratch paper to write and draw.
Two minutes later, he raised his hand and asked for dozens of scratch papers from the invigilator.
The teacher changed color on the spot, and for the sake of classroom discipline, he still didn't speak, just stood on the side, watching what the student was writing.
The handwriting is vigorous and vigorous, even if it is a number, it has a different kind of beauty when you look at it. The teacher's eyes lingered on the student's face, this child is definitely a top student, just with this good hand, I think it is a long-term practice.
Looking at the content again, the dense number sequence, he is also a math teacher, and after scanning a few lines, he found that the content was not in the topic at all.
What exactly is being written?
Any sufficiently large even number can be expressed as the sum of two prime numbers.
What is this? This is the Goldbach conjecture.
What is the situation of this student, in such an important competition, to do some meaningless moves.
The most cutting-edge contribution of Goldbach's conjecture is Chen Jingrun's proof of 1+2 in 1966, which caused a sensation in the world and was recognized by the whole world as "Chen's theorem". ”
And the most important 1+1 proof is that countless masters, racking their brains, have gained zero.
Seeing that the blank paper was smeared all over, the invigilator made a move that he couldn't understand, took out half of the draft paper from the podium and put it next to Yang Fan.
He looked at the name school on the exam paper, walked to the door of the classroom, and reported the situation to the teacher of the inspection team.
reported at the first level, and the inspection team found Feng Yao, who led the team.
"What do you say? My student is doing the Goldbach conjecture? What about his papers?"
"It's done, and the invigilator looks at it and says it might be a perfect score. ”
"In that case, let him do it well. Feng Yaodi's rigid face was unprecedentedly relaxed.
"Your student, the current situation is very wrong, I can't say it clearly, you can see for yourself. ”
This is worth it, Feng Yao knew Yang Fan's examination room, and let go of his pace and ran over. When he arrived at the door, he swept his eyes, and an invigilator was beside Yang Fan, his eyes moved with his handwriting, and the teacher had lost his soul, his focus was distorted, and his pupils were dilated.
And Yang Fan is in even worse condition, his eyes are bloodshot, his face is gray, and his forehead is bruised. I haven't seen it for just an hour, but I have made such a change.
Feng Yao understood that this was a demon, a spiritual death. The manic aura exuded from the whole body, standing at the door, I could feel the eagerness.
"Be fast, be faster, there's no time. Yang Fan has been mentally infected by Chen Jingrun, and one of his thoughts is Goldbach's conjecture, and for half an hour, his brain burned wildly, extracting his essence.
"Not good, not good." Feng Yao stomped his feet anxiously, this was in the examination room, and there were forty classmates competing, so he couldn't be disturbed.
"Get an ambulance. As soon as the bell rings, it's best to knock him out. Feng Yao instructed the members of the inspection team, and took out his mobile phone again: "Principal, Yang Fan, this student, something is wrong......
"Hurry up and inform his parents, I'll be here now. ”
The teachers in the corridor gathered more and more, and when they heard about it, they all became curious. In the competition, there were students who did the Goldbach conjecture? What kind of thing can students touch?
Who is it?
The teachers who were piled up together were all discussing in low voices.
"Does anyone know the progress? Is it really proving the conjecture?"
"Shhhh ”
"Which school is it, I haven't heard the name Yang Fan. ”
"Attached to the middle school, Feng Yao personally brought it out. ”
As soon as he talked about Feng Yao, he immediately understood. Four years ago, it was he who took a student and suppressed all the other three prestigious schools, which is definitely a shame.
It's acceptable for everyone to take turns sitting in the bank in the early one or two, and each time the game throws people away, which is a deep blow to the mathematical genius of that class.
Now, I'm afraid of another one. This Feng Yao, how can he be so lucky.
The examination venue was No. 9 Middle School, and the fat-headed and big-eared principal gave Feng Yao a roll of his eyes, and he was reluctant to come when he opened twice his original salary. No. 9 Middle School is the first in Wuzhou, no one can deny it, it's really ignorant.
He glanced at the students in the classroom again, that kind of obsession, that kind of seriousness, the more he looked at it, the more he liked it, the third year of high school just started, can he transfer to another school.
