Volume 1: Student Life Chapter 199 Come share with us
“…Here, if the conclusion holds when n=m, then when n=m+1, using the inductive hypothesis, we know that i=1∏m+1(kiA+1)/(A+1)=(i=1∏m(kiA+1)/(A+1))·(km+1A+1)/(A+1)≤(k1k2···kmA+1)/(A+1)·(km+1A+1)/(A+1)≤(k1k2···k m+1A+1)/(A+1).”
As Chen Zhou wrote, he asked Chen Xiao, "Do you understand this step?"
Chen Xiao shook his head, then nodded: "I can understand it, but it's a little difficult..."
Chen Zhou asked curiously, "What's so difficult?"
"Uh..." Chen Xiao said hesitantly, "This is how it should be done, but the key is that I can't think of the key steps..."
Hearing Chen Xiao's words, Chen Zhou smiled and said, "It's okay. It's normal that you can't think of it. The main reason is that your own knowledge reserves are not enough. There is only one way to solve it. Read more, think more, and accumulate more."
Chen Xiao nodded silently.
Chen Zhou put down the draft paper and continued, "Finally, using mathematical induction, we can make the inequality true for all positive integers n, and the proposition is proved. This question is mainly about the flexible application of induction, so think about it carefully."
"Yeah." Chen Xiao nodded, picked up the draft paper, and started thinking about it on his own.
Chen Zhou glanced at Chen Xiao and said nothing.
He stood up, gave his seat to Chen Xiao, then cut a piece of watermelon, washed some grapes, and brought them to Chen Xiao.
After doing all this, Chen Zhou looked at the time and returned to his room.
Sitting down at the desk, Chen Zhou began to make a detailed plan and break down his time.
Time is something that, as long as you manage it well, you will find that it actually has a lot of spare time that can be used.
Moreover, in a certain sense, time is movement.
The day we define is nothing more than one rotation of the earth.
The year we define is nothing more than one revolution of the Earth around the sun.
Therefore, saving time can also be understood as chasing the movement of the earth.
Thinking of this, Chen Zhou suddenly felt that the concept of time management had risen to a new level.
After all, the sport of chasing the earth is pretty cool just to think about!
After making a plan, Chen Zhou began to get into the rhythm of the afternoon.
Continue to study the hail hypothesis.
After a busy afternoon, Chen Zhou left several pages of heavy mistakes in the collection of wrong questions.
There is no way. So far, he still hasn't found a good idea.
What he can do is still to learn and research at the same time.
Continue to absorb knowledge from relevant literature and continue to try to solve the difficult problem of hail conjecture.
Putting down the work at hand, Chen Zhou rubbed his temples.
Studying and researching consume both physical and mental energy.
Chen Zhou felt a little tired.
At seven o'clock in the evening, Chen Zhou and Yang Yiyi were video chatting.
He began to continue his work from the previous morning, studying and summarizing the research materials sent by Dean Yang.
This is Chen Zhou's plan. He will spend the evening on Dean Yang's project, the afternoon on the hail hypothesis, and the morning on the physics department's textbooks.
In this fulfilling arrangement, Chen Zhou chases the movement of the earth.
In this way, Chen Zhou has not left the house for more than 20 days since he came back from summer vacation.
The reason he went out today was because Chen Xiao’s high school entrance examination results came out, and he accompanied Chen Xiao to the Third Middle School to find a teacher to fill out his application.
Just like the college entrance examination, you also have to fill in your application form after the high school entrance examination .
However, unlike the college entrance examination, the application process for the high school entrance examination is not that complicated.
The school has quotas for general enrollment, targeted enrollment and expanded enrollment.
Which school each student can go to is basically determined after checking their grades and rankings.
The full name of No. 3 Middle School is the Third Middle School, which is a junior high school.
This is also where Chen Zhou went to junior high school.
I went to No. 3 Middle School with Chen Xiao and found Chen Xiao’s class teacher.
Chen Xiao's class teacher didn't recognize Chen Zhou at first, but when Chen Xiao introduced him, he remembered him.
Wow, this is actually the top scorer in science in our province...
The head teacher quickly greeted Chen Zhou warmly.
This made Chen Zhou feel a little embarrassed.
Moreover, there were teachers from other classes and some students who also came to check their grades and fill out their applications in the head teacher's office.
Hearing the noise from Chen Zhou and the others, everyone looked at Chen Zhou curiously.
They had heard before that Chen Xiao had a brother who was a top scorer in the imperial examination, but this was the first time they had seen him in person.
Curiosity is inevitable.
Chen Zhou was naturally accustomed to being the center of attention, but Chen Xiao was obviously a little uncomfortable.
Because when he was with Chen Zhou, he felt a lot of pressure.
Fortunately, after Chen Zhou asked Chen Xiao about his grades and ranking, he was completely relieved.
I did very well in the exam, ranking first in the school, top in the county high school entrance examination, and top in the city high school entrance examination. I can go to one of the top high schools in the province.
This result is much better than Chen Zhou's back then.
Seeing that Chen Xiao had filled out the application form, Chen Zhou decided to leave with Chen Xiao.
At this time, a man walked in hurriedly.
Chen Zhou took a look and felt that it looked familiar, but he couldn't remember what it was for a moment.
The other party was different. They were obviously targeting Chen Zhou.
I saw this man walking towards Chen Zhou.
Chen Xiao's head teacher also stood up and greeted him: "Principal Ruan, why are you here?"
Hearing the name of Principal Ruan, Chen Zhou suddenly thought: Isn't this the vice-principal of No. 3 Middle School who was in charge of teaching and research and often caught him being late when he was in junior high school?
"I'm here to find our classmate Chen Zhou." Principal Ruan replied, and his entire gaze remained on Chen Zhou.
"Uh, hello, Principal Ruan." Chen Zhou hesitated slightly, but still spoke and greeted politely.
"Student Chen Zhou, why are you returning to your alma mater without saying hello ?" Principal Ruan's hearty voice made Chen Zhou quite embarrassed.
He's not a celebrity, and he's just accompanying his brother to fill out an application form, so why is he saying hello...
Chen Zhou looked at Principal Ruan and said, "Principal Ruan, what do you want to talk to me about?"
Principal Ruan did not beat around the bush and said directly: "I was embarrassed to bother you, and now that you are here at school, I was thinking, why don't you come and share your learning experience with our students, your younger classmates?"
Chen Zhou was slightly stunned. This Principal Ruan was really rude. It had been a year since he finished the college entrance examination, and he had never come to see him before...
But since the person had already said it, and it was in the name of his alma mater, Chen Zhou couldn't refuse.
What's more, in Chen Zhou's understanding, the school will probably gather a lot of students for this sharing, which should be able to gain some experience.
Thinking of this, Chen Zhou said, "No problem."
Principal Ruan was overjoyed and immediately said, "How about tomorrow morning, in the auditorium of No. 3 Middle School?"
Chen Zhou nodded.
Since others have already thought about it, you don’t need to worry about anything, so just wait and gain experience.
On the way home, Chen Zhou learned that No. 3 Middle School had originally planned to arrange the graduation ceremony tomorrow.
Chen Zhou then realized that he had forgotten this.
This has always been the custom of No. 3 Middle School. On the second day after the announcement of the senior high school entrance examination results, all the graduating third-year students return to school to participate in the graduation ceremony.
Chen Zhou was a little embarrassed.
