After 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 moment, my daughter is your super fan, I like your songs. You can sign a name. Otherwise, she will be whispered to death when I go back."

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?"

"You can just write a message."

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

Xu Ying took it and laughed. She saw the book, saying: Study hard and improve every day. Signature: Wu Zhe

Wu Zhe was also a little embarrassed. Seeing Xu Ying laughing, he hurriedly asked, "No? Why don't I rewrite it."

"No, no, that's great. I have something to say when I go back now, and my idols ask her to study hard."

After saying goodbye, the two of them came out, Wu Zhe sent a message to Wang Chao and asked where they were in class?

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

Wu Zhe came to 306 on the third floor with a familiarity, looked inside, and saw the calculus inside. The teacher was an old acquaintance Professor Yuan Wenshu.

Wu Zhe took advantage of Professor Yuan's chance to turn around and walked in through the back door.

But he underestimated his influence. When he saw Wu Zhe appearing in the classroom, many people still made surprise sounds.

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

Wu Zhe was rushing towards Wang Chao and the others.

"Wu Zhe, a rare guest! He didn't say hello when he came in." Professor Yuan said with a smile on his face.

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

"Okay, don't be polite. You're here, so you save me a lot of trouble! Come up and tell your classmates about these questions." Old Yuan took action against Wu Zhe.

Wu Zhe was stunned and smiled embarrassedly: "Teacher Yuan, let it go! Isn't it difficult for me? These are all classmates, and everyone is so familiar with them."

"If you come up, come up. Why do you talk so much nonsense? If you weren't in school this time, the school would definitely hold an academic seminar on "About the Sitapan Conjecture". At that time, you would be a well-known scholar sitting in the audience. Don't practice your skills now? When you make your grades, you won't have time to practice teaching and give you a presentation."

After saying this, Wu Zhe also knew that Professor Yuan was doing his best. To be honest, the professors and teachers from the University of Science and Technology are really very good to Wu Zhe.

When he got up, Wu Zhe came to the front of the whiteboard and looked at the topic above:

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

This is a proof question.

After a little thought, Wu Zhe untied it. He picked up the marker and wrote on the whiteboard:

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, that is, f(x) is continuous everywhere.

0≤|f(xo+△x)-f(xo)|≤l|Acr|

Take the limit Ax→0 for the above formula, and lim f(xo+△x)-f(x)=0, that is, f(x) is continuous everywhere on (a,b).

While writing, Wu Zhe also explained. He drew from those theorems, and then used which formulas to draw what results were obtained. Then he proved what was found.

Listening to Wu Zhe's explanation, Yuan Wenshu shook his head. Seeing Wu Zhe finished speaking, Yuan Wenshu said to Wu Zhe: "Wu Zhe! There is no problem with you doing the questions like this, but you can't do it if you give lectures and give reports. You are too detailed and don't talk about some obvious things."

Seeing that Wu Zhe was a little confused, Professor Yuan continued to explain: "This is a relatively simple mathematical problem. If it is a very advanced mathematical research, there will be many steps to prove the formula. Even if you express it in mathematical language, it may take a long time to speak. A report only has about an hour of statement time. For example, Fields divides the report into 45 minutes and 60 minutes. You have to express your point of view clearly in a limited time."

Seeing many people nodding subconsciously, Professor Yuan continued, "You must remember that in the future, the mathematical research meeting will be for those who can understand it. Even if you don't understand it, you will still not understand it no matter how detailed it is."

Now Wu Zhe really understood Professor Yuan’s words.

"Wu Zhe, continue to talk about the following topic." Yuan Wenshu pointed out Wu Zhe for a while and asked Wu Zhe to continue.

Wu Zhe bowed to Professor Yuan and continued to talk about the topic: "Look at this question, let's say that the function f(x) always has any two points x and y on the closed interval [a,b]|f(x)-f(y)≤Ix-y, where I is a constant, and f(a)f(b)0, prove that there is at least a little ξE(a,b), so that f(number)=0.------"

With Wu Zhe's continuous insights, his thinking on lectures and questions changed very quickly, but he only suffered the students below. He had already said very detailed words but didn't understand them. But Wu Zhe suddenly began to have the same style as the professors, and began to become messy in the wind again.

OK, it’s all the old man. Take your phone out and record the screen and study it carefully!

What Wu Zhe didn't know was that when he was giving a lecture, President Qi from the Young Academy took Zhang De to an office, and there were all people sitting in it that were highly respected at the University of Science and Technology, and Chang Yuanfang, the president of the University of Science and Technology, was also sitting in the first place.

Seeing Dean Qi coming in, Principal Chang smiled and said, "Old Qi, I'm waiting for you."

President Qi also clasped his fists to everyone and said, "Sorry, I've been waiting for a long time. But our institute organized a group of people to review Wu Zhe's project. So it's too late."

President Chang immediately asked anxiously: "How is the situation? You know this meeting is for Wu Zhe's genetic mapping project. Academician Zhang Wei submitted a report to the Chinese Academy of Sciences through a gene researcher. The Chinese Academy of Sciences now attaches great importance to it and has given us specific research tasks. So we also need first-hand information now."

President Qi nodded clearly and said, "Our hospital also knows that it is of great importance, so after Professor Zhang talked to me last night, I went to get the project report overnight and immediately arranged people for preliminary verification. The conclusion is: it is feasible. It can involve many subjects, and the scientific research strength of our junior college alone is definitely not enough."

President Chang replied with a laugh, "Old Qi, I'm going to make arrangements for you! You said that anyone here is not a subject leader. Read the project report first, and then talk about the others!"

After listening to this, Zhang Detong immediately sent a scientific research project report to everyone present, Wu Zhe applied for.

Several old experts held the copied manuscripts, and everyone felt good about Wu Zhe because Wu Zhe did not use a computer to make this report, but was written by hand. This is very in line with the preferences of the elderly, and Wu Zhe's handwriting is indeed very beautiful and has great skills.

One of the old professors in optics said: "This child is good, and this report shows that he has put a lot of thought into it."
