I reach the pinnacle of life by learning

How did you pass the test?

Qiao Yu was very puzzled by this question.

Qiao Yu thought for a moment: "I'll keep writing and writing, and I'll hand in the paper when the time is up. After the test, I'll check the score, 200."

The atmosphere was silent, with a little embarrassment.

The smile on Li Chujie's face froze slightly: "That's not what I meant."

Qiao Yu looked puzzled: "Then what do you mean?"

Of course, it is to ask about your problem-solving experience, learning process, etc...!Unexpectedly, Qiao Yu didn't play cards according to common sense.

If you answer like this, you will be sacked by the majority of students who have not passed the retest line.

Li Chujie took a deep breath: "It can be seen that you have studied college mathematics, and what have you learned?"

As soon as this was mentioned, Qiao Yu had to scold, the dog system is really harmful.

He could have been happy and happy, but the system made him ignorant and nightless.

About half a year ago, as a high school student, Qiao Yu encountered knowledge beyond her age group for the first time, and it was like a fateful encounter.

That's in the system's weekly task reminder.

The system gave him an "Introduction to Basic Number Theory".

Since then, Qiao Yu's weekly tasks have revolved around various math problems.

Sometimes number theory, sometimes arithmetic algebraic geometry, sometimes differential equations.

During countless sleepless nights, Qiao Yu used bottle after bottle of energy potion to get himself drunk.Banging my head against the wall for the proof steps in the paper, and not thinking about eating and drinking for an equation.Don't be afraid that some people are talented, just be afraid that some people are more talented than you, willing to work hard, and have an open system.

If it weren't for Qiao Yu's own excellent genes, it would be difficult to avoid the fate of going bald at an early age.

So, Qiao Yu is no stranger to math problems.

He has at least the level of a third-year undergraduate mathematics major.

After thinking for a while, Qiao Yu replied conservatively: "I have learned a little bit, number theory, differential equations, topology, algebraic geometry, and arithmetic geometry. I know a lot about these aspects."

Li Chujie was refreshed, and his sitting posture became more dignified: "Who did you learn from?"

After thinking carefully, Qiao Yu replied: "There are quite a few, Vinogradov, Chern Shiingshen, William Thurston..."

Vinogradov, the author of "Fundamentals of Number Theory", once served as the director of the Steklov Institute of Mathematics of the Soviet Academy of Sciences.

Chern Shiing-shen, a Chinese mathematician, one of the greatest geometers of the 20th century, must memorize elementary school textbooks.

William Thurston, a pioneer in the field of topology research, completed the topological classification of three-dimensional closed manifolds.

……

The smile on Li Chujie's face couldn't hold back anymore.

He felt that Qiao Yu was teasing him, or else it was the young man who let him go.

This time it was Li Chujie's question, and the difficulty of this test paper mainly focused on the last algebraic geometry question.

As a mathematics researcher, Li Chujie set up questions step by step. The last small question is the most difficult. Li Chujie is confident that no high school student in the country can solve it, but this question is only 2 points.

His original intention of setting up this question is to let these students experience the power of mathematics, so as not to learn a little bit of superficiality, and their tails will go up to the sky.

But unexpectedly, it was his eye-opener in the end.

He personally read Qiao Yu's answer, the process was rigorous, logical and perfect.Even the most picky graders can't find anything wrong with a magnifying glass.Moreover, Qiao Yu completed a test paper independently within 3 hours, and it was the first time he had seen the question.

The only problem is - this is a high school student's answering process.

Li Chujie was born in the branch of the Li family in Yanjing, and has no connection with the main branch, but he was born in the third ring of Yanjing, and his family is still very wealthy.

From the age of 7, he followed his father, who is a university professor, to lecture in universities and schools in various European countries, feeling the intoxicating fragrance of knowledge.

For most people, "When I grow up, I want to be a scientist" is just a general talk of elementary school composition written on paper, but for Li Chujie, it is his lifelong goal.

At the age of 17, Li Chujie received an admission letter from the Department of Mathematics of Princeton University with his excellent grades.

At the age of 27, Li Chujie finished his studies at the Clay Institute of Mathematics, declined the invitation to enroll as a doctoral student at the University of Berkeley, where Chern and Oppenheimer had both stayed, and returned to China in response to the call of the "Thousand Talents Program". A professor of mathematics at the university.

Although he is still an associate professor in his name, his conversion to a full-time job has already been put on the agenda.

I don't know why, but there is always a saying in the world that Huaguo has no soil for cultivating mathematicians.Li Chujie refused to accept, but he had no right to refuse.

Because they really didn't have any good results.Now the world's top academics are in the hands of Europeans and Americans...

Li Chujie asked himself, when he was a freshman in high school, could he solve this problem?

The answer is a small question mark.

"It seems that you have learned a lot." Li Chujie smiled more gently, "Looking at the answer to the last question of your test paper, you have studied advanced algebra."

The last question in the test paper is actually relatively easy to solve as long as you do some research on the determinant analysis method of the matrix eigenvalue theory.

Li Chujie asked a few random questions.The field of mathematics is too specialized. Even if it belongs to the second-level discipline of applied mathematics, a small branch can make scholars who study different branches unable to understand each other.

Since Qiao Yu made the last question, his questions naturally focused on the field of matrix algebra.

Li Chujie was just on a whim. He didn't expect Qiao Yu to answer fluently. It wasn't the kind of fluency that he simply recited, but he had his own understanding and thinking.

Principal Hao and Mr. Sun, the English teacher on the other side, looked at a loss.

Occasionally, a few obscure English words would pop out of Qiao Yu's mouth. Sun Yue had taught high school English for almost 15 years, but he didn't realize what Qiao Yu said.

With the assistance of the system and the blessing of 138.2 intelligence, the current level of learning is relatively easy for Qiao Yu.At least, the system has not been so frantic that he has to prove the Riemann Hypothesis or the Navel-Stoke equation.

The expression on Li Chujie's face gradually softened.

If he is really capable, he doesn't mind being arrogant... After all, when he went to other universities to give lectures, he was often licked and drenched by the school.

Li Chujie asked suddenly: "How old are you this year?"

Before Qiao Yu could speak, Principal Hao hurriedly replied: "Teacher, he is 17. He is the No. 1 in the freshman year of our school. He was No. 1 in the city in the joint entrance examination before. He is also an outstanding provincial Communist Youth League cadre. Qiao Yu Classmate Yu is really outstanding!"

Principal Hao tried his best to prove Qiao Yu's strength, but he was afraid that the fire of leaking the questions in the competition would spread to his students.

The lump in Li Chujie's heart slowly disappeared.

At the age of 17, he has already received the admission letter from Princeton, and Qiao Yu is still in the first year of high school.

But then, another pimple suddenly appeared.

17 years old, with this kind of talent, still in the first year of high school, it is really a waste... a waste of time!

"Qiao Yu, it's really good that you can study this far by yourself." He showed a gentle smile, and then took out a business card from his arms, "I am an associate professor of the Department of Mathematics, Yanjing University. Not only because of the leak, but also because I was invited to give a lecture on advanced algebra and topology in Tianhai. If you are interested, you can come and listen. It will be this Saturday afternoon, right after the exam."

Qiao Yu took the business card and whispered "Thank you".

Principal Hao on the side nodded hurriedly: "Definitely."

Li Chujie didn't say anything more, and left the office with the staff.

As soon as he got out of No. 7 Middle School, he sighed inwardly with some annoyance.

Li Chujie's status may be mediocre at Yenching University, but he once published a paper related to the Ridge curvature integral in the top journal "Iiones Mathematicae" ("New Advances in Mathematics") as a corresponding author .It was also this thesis that earned him an invitation from Berkeley University.

This means that in other slightly inferior books, Li Chujie can be regarded as a "school bully".In the admissions introduction, there may be a special introduction column.

Why was he so obsessed with ghosts that he threw an olive branch at a high school student.

The reason could only be that the words on Qiao Yu's math test paper were so beautifully written.

"If he chooses Yenching University in the future, he can come to my graduate school." After sighing, Li Chujie began to mutter to himself, "It's just too young, and college may not be good... When will Hua Guo be able to produce another Chen Shiingshen?" Woolen cloth?"

His expression was full of self-mockery.

As a Chinese, even if you study in the world's top universities, you will inevitably face some disturbing prejudices.

The small employees of the police station were stunned when they heard this, and felt that Professor Li was a little dazed.

Because I went to the office, by the time Qiao Yu returned to the small classroom, it was almost 8 o'clock.

Qiao Yuren was not there, and the class leader Ma Guanghui organized self-study in the small classroom.

In the 33-person classroom, the study groups are orderly. Even Song Tianyu, who doesn't like to study the most on weekdays, is patiently explaining chemistry problems to the members of the same group.

Qiao Yu was very pleased, as if he saw rows of bright points waving to him.

Qiao Yu picked up the lesson plan and stood on the podium: "Today we will talk about a big test of biology, heredity."

This class will also be put on the MK platform after a while for other students to learn.

Speaking of creatures, we have to mention the two main quests given by the system.

On the way back, Qiao Yu applied to Principal Hao for the key to the school's biology laboratory.

If you just do cell slices, the school's biology laboratory is completely sufficient.

Principal Hao readily agreed.Immediately, he took out the key from the lab teacher's pocket and handed it to Qiao Yu.

Principal Hao: "I understand. When I was studying biology in high school, what I was most looking forward to was going to the laboratory. It's just that the conditions were not good at that time, and the teacher could only do it on the top, and we could watch it from the bottom. Now that I have the opportunity to touch the instrument, I should touch it more. Bar."

The laboratory teacher hesitated to speak, and said that he didn't know who told him not to open the laboratory door if there was nothing to do. A microscope is super expensive, and its lifespan will be shorter after one use...

Now, there are still 12 days before the math competition league.In Qiao Yu's prediction, he planned to complete this task in 10 days.

100 cell slices, very simple, 10 slices a day, just finished by next weekend.

However, he found that this time he underestimated the task.

For the first time, Qiao Yu chose human oral epithelial cells and tissue slice experiments, which are the most readily available materials, and it was also the first experiment for countless middle school students.

He is calm and cautious by nature, and the cell slices he made in 33 minutes are as standard as those in the textbook.

However, in the judgment of the system, this slice is only a passing level.

The system gave a modification opinion: "The host has made invalid actions many times during the experiment, please pay attention to the time control of the host."

Got it, not only must it look good, but also be fast.

Qiao Yu tried again and again like a robot.Finally, after the 6th failure, I got a perfect cell slice.

He processed the second piece in the same way, and the system identification was still perfect, but the task progress was still 1/100.

The system cruelly said: "The same cell slices are not included in the task progress."

Qiao Yu: "..." Gan.

After leaving class 11, Qiao Yu walked into the laboratory with a newly bought onion.

He has not only onions in his pockets, but also cucumbers, tomatoes, and bananas.

For the task of slicing biological cells, Qiao Yu had already attacked the animals in the school for a round, and now it was finally the turn of the plants.

Now, the campus rumors related to Qiao Yu started to be updated again.

Everyone said that Qiao Yu cooked crucian carp soup in a retort in the biology laboratory.

Otherwise why would he bring a fish into the lab?

Qiao Yu didn't know anything about it.

Under systematic training, he has now become a skilled slicer.You only need to look at the material to recall the simplest and time-saving operation method.

If this is a university laboratory, then he must be a technical job that the instructor appreciates.

Qiao Yu's experiment time is fixed between after school in the afternoon and before the evening self-study class.There is a full hour and a half, but there is not much time left for him to actually operate.Fortunately, he found free labor.

He took off his white gloves and began cleaning the slices.

On the other side, Song Tianyu hurriedly put the reagents back in place.

While Qiao Yu was doing experiments, Song Tianyu was doing homework on the next table.

Song Tianyu never asked him why he made these strange slices.

With the improvement of Qiao Yu's technology, Song Tianyu also became proficient in tidying up the laboratory.

Sometimes, as soon as Qiao Yu opened his hands, Song Tianyu knew whether the other party wanted tweezers or blades.

Qiao Yu is actually not used to having people around her.

But now, he feels that the word "habit" is not all derogatory.
