Academic tyrant: I have become a prodigy since I was able to pursue my academic career with peace of

Nothing happened at the bar, which made Chen Fan very happy. However, Chen Fan still listened to Liu Dong and Lin Qiuyu's ideas.

In the theoretical task of choosing one of three, Chen Fan could complete the last one, or he could choose a love relationship to earn academic points, but the Mersenne prime number was the first.

This is a challenge.

Current mathematics can no longer satisfy Chen Fan, or in other words, Chen Fan intends to hit a higher world, a higher world of mathematics.

Zhou Siyu was taken away, and of course Zhang Rongrong also drank too much.

If he hadn't been drinking with Lin Qiuyu, he probably wouldn't have been so uncomfortable.

It was impossible to go home. Zhang Rongrong's family was a traditional family. If he knew that his daughter had gone to a bar, he would probably break Lin Qiuyu's legs.

Temporarily living at Lin Fan's house, of course, Zhang Rongrong herself was very happy.

Late at night, Chen Fan was sorting out information. Seriously, Mersenne prime numbers are really fascinating.

But still exercise restraint.

Throughout the research history of Mersenne prime numbers, this is a history of development. Countless predecessors have used countless sweat to tell everyone that Mersenne prime numbers are actually of no use.

How is the research?

In 2006, there were results, but they were not recognized by everyone.

In China, Zhou's conjecture is infinitely close to the Mersenne prime number.

"dad."

Chen Keke walked into the study room

"whats the matter?"

"I peeled the apple for you, Dad. I have something to tell you."

Chen Fan turned his chair and looked at his daughter

"you say"

"Dad, my mother has been gone for so many years. After so many years, haven’t you thought about looking for her?"

"No."

What a straight man, it's really uncomfortable

"Well, my aunt seems to be very interested in you."

"They are sisters, and they were in the same class as me back then, but I rose quickly and reached the level of a mentor very quickly. They became my students. I chose your mother over her." ah?

"Why, dad, my mom doesn’t look that smart."

"She is very smart, but her health is not very good. She can do very little research and the results she produces are also very low. When the 4G algorithm broke through, your mother participated in the calculation. It can be said that your mother and I were at the same time. It was completed, but later, when she gave birth to you, she still couldn't survive it."

Alas.

Chen Keke blames herself very much. She has known about this for a long time.

But she doesn't know how to tell her father about her self-blame.

"Well, Dad, are you angry with me?"

"Why am I angry with you? Oops, I remembered. The psychology professor at school told me that you will blame yourself for the death of your mother. Don’t worry, you don’t have to blame yourself. I should be the one blaming myself for life, old age, illness and death. If I am stronger, I can break through. My limit, then I might really bring her back. Your mother had a genetic problem, but fortunately, it did not appear in you."

Genes, God's forbidden area, are more serious existences than the brain.

"Well, dad, I have one more thing"

"What about Zhang Rongrong?"

"If you really like Zhang Rongrong, you can talk, but please don’t hurt her heart. She is my best best friend."

"I know, I know propriety."

The next day, Chen Fan went to Peking University as usual, preparing for new things.

The calculation of Mersenne prime numbers, plus an invigilation.

This time the invigilation was very simple.

The selection was for the national team, that is, the National Mathematical Olympiad team, from each province.

The first person came to form a team, with a total of sixty-seven people.

The person who asked the question was Chen Fan, and the person who helped Chen Fan was Huang.

Zhong was the teacher who led the team in the previous year, but the first two years were not ideal.

In the third year, the country issued a death order and the championship must be brought back.

Chen Fan took the microphone, coughed and said,"You guys are. Come to participate in the Mathematical Olympiad competition. I hope there will be no fraud. If your test score is particularly low, I think I will doubt your own performance in the provincial Mathematical Olympiad competition. The test time is after lunch, and you have an afternoon. time to do the questions, and a whole morning to think about whether to participate."

After that, Chen Fan left.

"Teacher, who is this person?"

"he? That's the professor who needs to be written in the textbook."

"You are so young. After looking at more than 30 games, you are now a professor?"

"If he hadn't gotten married and raised children, I think he might have been out of reach of you. Remember, in academic terms, at least in the field of mathematics, he is the only one."

Nima, it's too scary to be led by such a giant Buddha.

In the office, Chen Fan was calculating on the draft paper

"Professor Chen, if you do this, you will easily offend others."

"Teacher Huang Zhong, when you taught me back then, weren’t you ruined by these cheaters?"

"Alas, there is no other way, the environment is like this."

Chen Fan said:"What the environment is like has nothing to do with me. I never care about it, because mathematics will not lie. It is clear at a glance. If you want to go through the motions and get gold plating, it is impossible here. I don't care about the other party. who is it."

Huang Zhong sighed.

It was twelve o'clock at noon. After everyone had eaten, they gathered on the playground.

There were no shortage of people, sixty-seven of them. To withdraw now would be equivalent to admitting that he had cheated. Even if he got zero points, he would still get Come on bravely

"My decision will not change, and I know what you think, but it has nothing to do with me."

The students came in one after another.

The papers were handed out and the students finished their work steadily.

Then they looked at the papers.

It is known that in the isosceles right triangle ABC,∠BAC=90, A.D.=AE，AF⊥BE intersects BC at F, draws FG⊥CD through F and intersects the extension line of BE at G. Prove: BG=AF+FG.

Anyone familiar with mathematics knows that the shorter the question is, the more difficult it will be.

One question per page, six pages in total.

The six questions are completely based on the International Mathematical Olympiad competition.

Forty-two points.

One question is worth seven points.

Damn, how do you calculate this kind of question? ps: Please support me, thank you all, I hope you can give me flowers and comments and support.
