Reshaping life starting from the Junior Class of HKUST

Chapter 209

At the end of the interview, Wu Zhe, Xu Ying, and the camera brother shook hands respectively.

Wu Zhe wanted to leave immediately, but Xu Ying stopped him: "Wu Zhe, wait a minute, my daughter is a big fan of yours, and she likes your songs. Please sign her name. Otherwise, I will be killed by her when I go back." Long-winded to death."

Wu Zhe blushed a little, this was the first time someone asked him for an autograph.

He took Xu Ying's signature pen and asked, "Sister Ying, what are you writing?"

"Whatever you want, just write a message."

Wu Zhe wrote a few words in a hurry, and handed back the notebook and pen to Xu Ying.

Xu Ying took a look and laughed.I saw the flying dragons and phoenixes written in the notebook: study hard and make progress every day.Signed by: Wu Zhe
Wu Zhe was also a little embarrassed. Seeing Xu Ying laughing, he hurriedly asked, "Can't you? How about I rewrite it."

"No, no, it's fine. I'll have something to say when I go back now, the idols let her study hard."

After saying goodbye to the two of them, Wu Zhe sent a message to Wang Chao, asking where they had classes?

Soon, Wang Chao's news came back: 306.

Wu Zhe came to 306 on the third floor familiarly, and looked inside, and there was the calculus on the inside.The teacher is an old acquaintance, Professor Yuan Wenshu.

Taking advantage of Professor Yuan's turning around, Wu Zhe slipped in through the back door.

But he underestimated his own influence, seeing Wu Zhe appearing in the classroom, many people still made surprise voices.

Hearing the noise behind, Professor Yuan also turned around and looked over.

I saw Wu Zhe's waist was squeezing towards Wang Chao and the others.

"Wu Zhe, a rare visitor! You don't even say hello when you come in." Professor Yuan said with a smile on his lips.

"Hi Teacher Yuan, it doesn't matter that you are busy, don't you have the nerve to disturb me?" Wu Zhe could only stand up straight and replied.

"Okay, don't pretend to be polite. It just so happens that you are here, and it will save me a lot of trouble! Come up and explain these questions to your classmates." Lao Yuan beckoned to Wu Zhe.

Wu Zhe was taken aback, and said with a sneer: "Mr. Yuan, let's forget it! Don't you make things difficult for me? These are some classmates, and we all know each other so well."

"Come up as soon as you come up, why are you talking so much nonsense! If you weren't at the school this time, the school would definitely hold an academic seminar on "Sitappan's Conjecture". At that time, you would be sitting under the stage with well-known scholars." Don't you want to practice your hands now? When you make your grades, there will be no time for you to practice such lectures and reports."

Having said that, Wu Zhe also knew that Professor Yuan was doing it for his own good.To be honest, the professors and teachers at HKUST are really very kind to Wu Zhe.

After getting up to go on stage, Wu Zhe came to the front of the whiteboard and looked at the topic on it:

Suppose the function f(x) is meaningful for any real number, and for any real number x, y, f(x+y)=f(x)+f(y), try to prove that if f(x) is at x=0 is continuous everywhere, then f(x) is continuous everywhere within negative infinity and positive infinity.
This is a proof question.

After Wu Zhe thought for a while, he untied it.Grab a marker and write on the board:
if(0+0)=f(0)+f(0), then f(0)=0.Vo∈R, f(xo+Ax)-f(xo)=f(xo)+f(Ar) -f(0)=f(Axr), so lim f(xo+△x)-f(ro)=lim f(Axr)= f(0)=0, ie f(x) is continuous everywhere.
0≤|f(xo+△x)-f(xo)|≤l|Acr|
Taking the limit Ax→0 for the above formula, there is lim f(xo+△x)-f(x)=0, that is, f(x) is continuous everywhere on (a, b)——
While writing, Wu Zhe also explained.From those theorems, what results are obtained from which formulas.Then prove what happened.

Listening to Wu Zhe's explanation, Yuan Wenshu shook his head.Seeing that Wu Zhe had finished speaking, Yuan Wenshu said to Wu Zhe: "Wu Zhe! It's okay for you to do the questions like this, but it's not good for lectures and reports. You have explained in too much detail. Don't talk about some obvious things."

Seeing that Wu Zhe didn't understand, Professor Yuan continued to explain: "This is a relatively simple mathematical problem. If it is a very advanced mathematical research, there will be a lot of formula steps to prove. Even if you express it in mathematical language, you may need to explain it. A long time. And a report will only have about one hour of presentation time. A report like Fields will be divided into 45 minutes and 60 minutes. You have to express your point of view clearly within the limited time.”

Seeing many people nodding subconsciously, Professor Yuan continued: "You have to remember one thing, in future mathematics research conferences, it is for people who can understand, and for those who don't understand, you just have to explain it carefully. Still don't understand."

Now Wu Zhe really understood what Professor Yuan said.

"Wu Zhe, continue with the next topic." Yuan Wenshu asked Wu Zhe to continue.

After Wu Zhe bowed to Professor Yuan, he continued to talk about the topic: "Let's look at this question, suppose that for any two points x and y on the closed interval [a, b], the function f(x) always has |f(x) -f(y)≤Ix-y, where I is a constant, and f(a)f(b)<0, prove that there is at least one point ξE(a,b) such that f(number)=0——"
-
With Wu Zhe's continuous insights, his thinking about lectures and problem-solving also changed quickly, but it was hard for the students below. He could still understand what he said in detail.But Wu Zhe suddenly started to have the same style as the professors, and the wind started to be messy again.

Yes, they are all uncles.Obediently take out your phone to record the screen and go back to study it carefully!

What Wu Zhe didn't know was that when he was lecturing.Dean Qi of the Junior College took Zhang Detong to an office, which was filled with people who could be said to be highly respected in the University of Science and Technology, and Chang Yuanfang, the principal of the University of Science and Technology, was also sitting in the first place.

Seeing Dean Qi coming in, Principal Chang greeted with a smile: "Old Qi, I'll just wait for you."

Dean Qi also clasped his fists at everyone and said, "I'm sorry, everyone has been waiting for a long time. It's just that our courtyard first organized a group of people to review Wu Zhe's project. That's why we came late."

Principal Chang immediately asked anxiously: "How is the situation? You know that this meeting is for Wu Zhe's genetic mapping project. Academician Zhang Wei submitted a report to the Chinese Academy of Sciences through a genetic researcher. He gave us specific research tasks. So now we also need first-hand information.”

Dean Qi nodded clearly and said: "Our institute also knows that the relationship is very important, so after Professor Zhang told me last night, I immediately arranged for people to conduct a preliminary verification of the project report I went to get overnight. The conclusion is: It is feasible. There are many disciplines that can be involved, and the scientific research strength of our junior academy alone is definitely not enough."

Principal Chang laughed and replied: "Old Qi, I'm making an arrangement for you! Which one of you here is not a subject leader, so let's read the project report first, and then talk about other things!"

After Zhang Detong listened, he immediately sent a report on the scientific research project that Wu Zhe applied for to everyone present.

Several old experts held the photocopied manuscripts, and everyone had a good impression of Wu Zhe, because Wu Zhe didn't use a computer to make this report, it was a handwritten report.This is very much in line with the preferences of the old people, and Wu Zhe's handwriting is indeed very beautiful and very solid.

One of them, an old professor of optics, said: "This kid is good, and this report shows that a lot of thought has been put into it."

Principal Chang sighed in his seat: "I have heard of Wu Zhe's name for a long time, and the Chess Academy still wanted to find me to poach someone. It's just that due to various reasons, I haven't seen it. This time, I have to meet our one. Now I can It is said that he is a young genius who is famous all over the world."
