I reach the pinnacle of life by learning

Li Chujie has been concerned about the school's admission list these days.

Although, he asked Qiao Yu before, Qiao Yu said that his first choice was Yenching University.

But Li Chujie was still not at ease.

After all, if what Qiao Yu reported was Guanghua School of Management, compared with the School of Mathematics, it would not seem so advantageous...

Qiao Yu has always been a very assertive person, which made it impossible for Li Chujie to interfere too much in his decision-making.

What he can do is to brag about the School of Mathematics of Yanda University on WeChat, as if he can catch up with the Premier League and the United States in no time, and if he joins, he can reach the pinnacle of life.

In mid-July, Yanda’s admission list finally came out.

Director Wang, who had received the notice a long time ago, sent Li Chujie a copy of the admission list of each department without stopping.

Professor Zhou, who was in the same office, was puzzled: "What about you, Lao Li? Although national gold medals and provincial champions are rare, it's not like we don't have them at Yanda."

Li Chujie just shook his head and sighed, "You don't understand."

Is it hard to have a Maxima, or is it hard to have a bole?This matter, I am afraid only God knows.

Li Chujie directly ctrl+f, and searched for Qiao Yu's name in the form.

The next moment, he suddenly opened his eyes wide.

"Qiao Yu, why, why..."

"Why did you choose a creature?"

Knowing the final result, Lu Miao screamed strangely on the phone.

His younger sister, Lu Yun, is also taking the college entrance examination this year, but she has just passed the first line, and her scores are not up or down, which is very embarrassing. Now the whole family is worrying about her volunteering.

Lu Yun asked what major Qiao Yu wanted to choose.

Lu Miao casually said a word about mathematics without research, so Lu Yun, a girl who only scored 92 points in mathematics in the college entrance examination, was determined to learn mathematics.

"Is it surprising?" Qiao Yu felt a little strange, "The research in the laboratory has always been in the direction of biology. It's not surprising to apply for biology."

Song Tianyu scored 666 points in the college entrance examination. His first choice was biological science, and his second choice was basic medicine.

According to the past data of Changning Province, Yanda’s admission line is between 640 and 660.The admission line of Tsinghua University is around 650.

Chu Xining's college entrance examination score was 717, which was among the top ten in the province.

However, he is already planning to study abroad, and scores mean little to him.

Even so, it is still a joyful thing in the environment where exams are paramount.

among the people around.The only person who was happy to report to Qiao Yu as a biology major was probably Mr. Lin Feng.

During dinner, I happily drank several glasses of white wine, but no one else could persuade me.

"I will go to Beijing another day, and I will introduce my old colleague to you." Lin Feng laughed heartily, recalling the past years, "At that time, I was still teaching at Yanda University, and I rode a bicycle to visit the scientific research institute in Zhongguancun on weekends... ...It was all 30 years ago. Your grandpa was there too, but he didn’t like to go out with us. Your grandma was not in good health at that time. Old Joe liked to move a stool and stay by your grandma’s side, slowly Do the math."

"When you were just born, everyone said that you looked like your mother. In fact, you are most like your grandma. She was very beautiful when she was young. It's a pity that she is not in good health. So is Qiao Qianlong, and you are Qiao Yue. Fortunately, you are not. Fortunately, you are not. You are not..." Lin Feng grabbed his hand and babbled, this academician who was nearly 70 years old suddenly burst into tears.

He looked so sad that Qiao Yu had no choice but to comfort him softly.

It took Lin Feng a long time to relax.

"Don't mention these things. I'm getting old, and I can't see birth, old age, sickness and death. You juniors will laugh at me." After Lin Feng finished speaking, he stood up with a cane, "I was cleaning up the old house before and found something by accident. It belongs to your grandfather."

"When your grandma passed away, Old Qiao aged ten years overnight. She told me to entrust this book to me...you can ask me for it later when you are in the mood."

As a result, Qiao Qianlong never asked for it again.

Qiao Yu followed him to the study.

Chu Xining, his grandson, was shut out instead.

Qiao Yu stared at Lin Feng's back bent over looking for something, feeling inexplicably sad.

When we met for the first time, Lin Feng's hair was also grizzled, but he was in good spirits.

Now that three years have passed, Lin Feng is like the sun at sunset, who knows when the last ray of light will be drowned by the sky.

Lin Feng quickly found what he wanted, which was a yellowed notebook.

He turned his head and handed the contents inside to Qiao Yu: "I have never opened it for so many years. Take it."

On the way back, the system couldn't help complaining to Qiao Yu: "He's like a novice village NPC who gives away equipment."

Qiao Yu lowered his head and looked at the notebook in his hand.

It can be seen that this notebook is quite old, and even the paper on the title page is slightly yellowed.

On the first page of the notebook were written "Qiao Qianlong" in big characters.

His grandparents left early, so Qiao Yu didn't know how to get along with the elderly.

But judging from the handwriting, Qiao Qianlong should have a personality completely different from his, more gentle, probably like Chu Xining.

Qiao Yu didn't open it to read the content, but waited until Qiao Yue came home.

"Grandpa's things are from Grandpa Lin Feng." He handed over the things in his hand.

Qiao Yue, who had just got off work from the dessert shop, had obvious shock on her face.

Song Tianyu had always praised Qiao Yue's delicious desserts before, but now Qiao Yue really opened a dessert shop in the business district near the school.

Because Qiao Yu secretly bought the shop she rented, her monthly loss is not much, and she can still make some money occasionally.

Over the years, Qiao Yu had accumulated enough points to buy back the five courses of medicine that Qiao Yue needed.

Now Qiao Yue's body is even healthier than ordinary people.

The system had instigated him many times, hoping that Qiao Yu could use the [-] points wisely, such as buying equipment, buying analysis diagrams, etc., but Qiao Yu seemed extremely stubborn, and used the most stupid method to buy medicines at the original price.

Qiao Yu doesn't care if it's worth it or not, he just hopes that nothing will happen to Qiao Yue in this life.

She is Qiao Yu's only relative in this world.

Only when Qiao Yue is present can Qiao Yu realize that he has a family.

"Is it... father's thing?" Qiao Yue asked cautiously.

Qiao Yu: "Yes."

Qiao Yue sat down at the dining table, her lips parted slightly, and she was speechless for a long time.

She stroked the cover, hugged it to her chest suddenly, lay down on the table and burst into tears.

Qiao Yue's mood didn't stabilize until more than ten minutes later.

She is in her 40s, and she is still crying like a child in front of her son, which is really embarrassing.

Qiao Yu poured her a cup of sugar water and put it in front of her: "Drink some."

Because he is not good at caring for others, his tone of voice seems too calm.

Qiao Yue's emotions were appeased.

Qiao Yu was precocious, and she rarely showed her emotions since she was a child. Instead, she looked more like an adult in front of her mother.

She opened the notebook left by her father, and the slight sadness in her expression was quickly replaced by blankness.

"Little Qiao," she put the notebook in front of Qiao Yu, "This seems to be his work notebook, I can't read it."

Qiao Yu glanced at it, and found that it was full of formulas and letters, and occasionally there were a few Chinese annotations, which Qiao Yue probably couldn't understand.

"Let me see what is written..." Qiao Yu said.

After saying this, he seemed to be frozen in front of the table, not moving.

Qiao Yue sat on the side, waiting patiently, until her arms felt a little sore on the ground, and then asked in a low voice, "Little Qiao, do you see anything?"

Qiao Yu seemed to be frightened, and suddenly stood up!

Qiao Yue was taken aback by his actions, blinked and asked, "What's wrong?"

Qiao Yu raised the notebook: "Sorry, I'm going back to the bedroom. Don't bother me today."

After speaking, he returned to his room.Sitting at the desk, he reopened the notebook.

Qiao Yu has been watching for more than ten minutes, but he is still not sure, or rather, not sure what he saw.

But the first line of Qiao Qianlong's notes already gave the answer.

【Proof of Goldbach's conjecture】.

One day hundreds of years ago, Goldbach wrote to Euler and made a conjecture: any natural number greater than 5 can be written as the sum of 3 prime numbers.

Not long after, Euler wrote back and added: Any even number greater than 4 is the sum of two prime numbers.

This is the famous Goldbach conjecture.

More than 40 years ago, Chen Jingrun made the biggest breakthrough in this conjecture. He proved that "any large even number can be expressed as the sum of a prime number and the product of two prime numbers." According to the media, this conclusion is only one step away from the final answer. remote.

This proof, until today, represents the pinnacle achievement of Huaguo mathematics.

Goldbach's conjecture is too famous, not only because of its own mathematical value, but also because of the serious lack of self-confidence of Chinese people in the 70s.

After Chen Jingrun proved that he was one step ahead of the finish line, his deeds began to be hyped by the media, which greatly boosted the national self-confidence.

Unlike the Riemann conjecture or the Poincaré conjecture, Goldbach's conjecture seems so simple that until now, every year, civilian scientists have stated in various mathematics forums that they have proved Ge Guess.

But just because it looks simple doesn't mean it's really simple.

Countless mathematicians fell before it, and generations of people stood up.

This is a jewel in the crown of mathematics, but so far no one has been able to pick it.

Qiao Yu's hands were almost trembling at this moment, and her ears were buzzing, so that she couldn't hear Qiao Yue's voice clearly.

This is the derivation process written by Qiao Qianlong, a thick book, Qiao Yu directly turned to the last page.

The proof on the last page was only half written, and a line of words was attached.

"Am I wrong?"

There was a long silence.

What surprised Qiao Yu was that according to Qiao Qianlong's notes, he had already proved Goldbach's conjecture.

The only problem is that Qiao Qianlong used a theory that has not been proven in it, called the twin prime number conjecture.

It's like doing a math problem. Obviously there is no such condition, but in order to get the result, I created a condition myself.

According to Lin Feng, Qiao Qianlong has never opened it since his grandmother passed away.

That's been close to 30 years.

Qiao Qianlong's proof has never moved forward.

The system said at this time: "[Random task] Prove Goldbach's conjecture. Reward: 3000 points. There is no penalty for failure."

Qiao Yu was silent for a moment: "...It's a bit too exaggerated."

The general perception in the mathematics community is that although Goldbach's conjecture is correct, it will probably never be proven.

Let him prove it?

Let others know, it may be like hearing a child say that he wants to go to the sky to pick up the stars.

It is also very romantic to have ideals, but it sounds childish and ridiculous.

The system said: "I don't know if the host has heard a sentence, mathematics is the field of genius."

"And you are the only one selected by the system from 70 billion people."

The author has something to say: Heart: Joe is only a freshman, is it too exaggerated to let him prove my brother guess now?

——It doesn't matter, it was Qiao Qianlong who proved it anyway!Qiao Qiao only needs to prove the twin prime number conjecture~

Heart: Grass, that's too exaggerated! !
