Research starts with PhD students

Chapter 142 Zhang Shuo calculated the winning number! ? This is not a rumor!
Science Building, large classroom on the first floor.

Nearly two hundred seats were filled, with many people standing in the back rows and even a lot of people crowded at the door.

There is also a row of seats on the side of the classroom.

Tan Youming, Qi Zhixiang, Wang Hui, Luo Yongjun and others were sitting there. They came just to watch the lecture and to support Zhang Shuo.

They were worried about something going wrong because it was Zhang Shuo's first time giving a lecture to students, and if any problems arose during the lecture, they could do something to remedy the situation.

Sun Xingli did not sit in a seat at the side. He did not want to sit with a group of middle-aged and elderly men, so he simply disguised himself as a student and sat in the back. As a result, he was recognized by the students.

Then, he consciously went to stand in the corner of the back row, but was still stared at by a lot of students in the back row.

Zhang Shuo's arrival helped to resolve the situation.

Under the gazes of many people, Zhang Shuo walked into the classroom from the front door and went straight to the podium. He glanced at the time, but before he could say anything, there was already a lot of applause in the classroom.

Zhang Shuo smiled and pressed his hands down, then said into the headset, "I haven't said anything yet, and everyone's already applauding. This makes me nervous!"

Many people laughed.

He continued at his own pace, turned around and wrote seven big words on the blackboard - Mathematical Research and Application.

Then, crossed it out.

In the face of everyone's confused gazes, Zhang Shuo explained, "Mathematical Research and Applications is the name of this course, but in fact, the name doesn't make any sense. The field of mathematical research and application contains too much content."

"This is my first time giving a lecture to students. To be honest, I am a little nervous, so I won't talk about the very professional content. Let's start with mathematical research."

"Many people asked me a question. They asked Zhang Shuo, how do you do research? How can you publish so many papers in a year at such a fast pace?"

“In short, they asked me for tips on how to do research.”

When hearing this, everyone became much more serious and the classroom became very quiet.

They wanted to know how Zhang Shuo did his research.

Zhang Shuo said two words, "Talent!"

“Hula~~~~”

The classroom suddenly went from quiet to bustling.

Zhang Shuo stretched out his hand and pressed it down, and continued, "This is a joke. In fact, everyone has different talents and ways of thinking, so of course there is no commonality in research."

“So I feel that my own research methods and my own experiences cannot help others.”

"I'm not saying that I have talent, but I'm talking about another issue, the core of research—"

He turned around and wrote three words - innovation.

“When we do mathematical research, we must abandon our traditional thinking and be innovative.”

"There is an international standard for judging mathematical achievements, which is whether the research is innovative. Innovation is very important. It means developing a new method and conducting a completely new research..."

Zhang Shuo focused his discussion on innovation.

His discussion was not a long speech, but rather he used several prepared examples to illustrate his ideas, and he would interact with students in the middle.

This kind of explanation is very interesting.

Everyone in the classroom listened very carefully and many people gave high praise.

Tan Youming listened for a long time and commented, "Zhang Shuo is not at all stage-frightened. He feels like an experienced professor. I am still worried about what might go wrong."

Qi Zhixiang nodded in agreement, "Yes, it is indeed amazing. I feel it is even better than what I said. There will be no problem for him to teach the class."

“This is genius.”

Wang Hui said depressedly, "I am not so casual in class. It seems that he has no ideological burden and is very relaxed when explaining."

"Don't you even look at whose students they are?"

Luo Yongjun smiled complacently and said, "How can the students I teach be bad?"

The people around rolled their eyes, but there was no way to refute.

Who made Luo Yongjun Zhang Shuo’s mentor?

……

Zhang Shuo spoke for 45 minutes straight, stopping to rest for ten minutes before moving on to the next part.

The next step is the application of mathematics.

He talked about some prepared content, cited several examples from life, and talked about how to use mathematics to clearly express and analyze things in life.

Of course, in this regard, mathematical description of physics is more convincing.

Therefore, he also cited several physical mathematical model frameworks, and then used solutions to conduct mathematical analysis of specific physical phenomena.

This part is also the most professional content in the course.

Then he jokingly talked about some incorrect applications of mathematics, and later used his own lottery buying experience as an example.

"There was an interesting thing last week."

Zhang Shuo said, "Professor Sun Xingli and I studied the winning lottery numbers together."

"We used more than a dozen methods to analyze past winning numbers, involving statistics, function theory, differential equations, and even some algebraic geometry expressions to perform complex number operations..."

Everyone listened carefully.

Zhang Shuo continued, "We researched several sets of numbers, one of which had the highest probability, and the others were similar, and then we bought lottery tickets for several draws in a row."

"In the end, I didn't even win a small prize. Even if I randomly picked numbers, they would be more reliable than the numbers we researched."

“This is a negative example of mathematical application!”

While Zhang Shuo was giving examples, many students in the back row looked at Sun Xingli.

The people standing behind him also looked over and asked, "Is what Professor Zhang Shuo said true?"

"Uh~~~"

Sun Xingli endured the gazes of the people around him. He felt that he should not have come here. He muttered silently in his heart, "Why do you talk about yourself?..."

Then he took out a lottery ticket from his pocket, showed it to the person next to him, and said blankly, "Look, it's the Hong Kong City Mark Six Lottery, but I didn't win."

Many people laughed. On the podium, Zhang Shuo continued, "So sometimes, mathematics is not omnipotent."

"When we consider using mathematical methods to analyze something, we must also consider whether the thing can be analyzed..."

He talked about this topic for another ten minutes, then looked at the time and ended his lecture.

The next step is to enter the free question session.

Zhang Shuo will answer students' questions, which is equivalent to face-to-face communication.

This is where things get interesting.

Some of the students' questions revolved around research, but most of them revolved around Zhang Shuo himself. One girl even asked him if he had a girlfriend.

Then a student asked, "Professor Zhang, can you tell me about the lottery numbers you studied?"

Zhang Shuo was stunned for a moment, then laughed, "This isn't gambling, is it? I've already said that all those Mark Six lottery tickets online are fake. We bought this lottery ticket from someone in Gangcheng."

“This must be emphasized!”

"Also, after I lose the numbers, if any of you win the lottery, you have to give me half of the money."

He said this very seriously, which made the whole classroom burst into laughter, with many students shouting, "No problem!"

"I agree!"

"Whoever wins the prize must give Professor Zhang half of it!"

Zhang Shuo nodded in satisfaction, and then wrote a string of numbers on the blackboard, "This string of numbers is the result of the analysis, and it is also the number we think is the most likely."

“Of course, this is pseudo-math.”

"Lottery winning number analysis is invalid from the beginning. No matter what analysis method is used, it is meaningless."

"Of course, I emphasize again that you can buy one or two tickets occasionally as entertainment, but don't get addicted to it. We study mathematics and can easily calculate the probability of winning."

"If you use a covering purchase method, the only result is a loss..."

……

The lecture is over.

Several professors gathered around.

Tan Youming praised Zhang Shuo's final example, "Your example of studying lottery with Sun Xingli is really interesting."

"All the students were listening attentively at that time. It was very relevant to our daily lives!"

Qi Zhixiang smiled and said, "Some time ago, I saw them doing research and wanted to persuade them. We mathematicians know that this thing is meaningless."

Luo Yongjun nodded and said, "It really doesn't make any sense. If lottery tickets could be researched, other people would have done it long ago."

He muttered softly, "It's all Sun Xingli's fault. Dali always thinks of some crooked ways and even drags Zhang Shuo into it..."

"I heard."

Sun Xingli's voice suddenly appeared behind Luo Yongjun, "We are obviously doing research together, I am confused, why don't you think it was Zhang Shuo who pulled me?"

Luo Yongjun, Qi Zhixiang and Wang Hui looked at Sun Xingli together.

Wang Hui asked, "Who is pulling whom?"

"Ahem... It was my suggestion, but Zhang Shuo is also interested, and..."

"Don't bother."

Luo Yongjun interrupted him and nodded vigorously, "That's the reason."

……

After the lecture, Zhang Shuo, Sun Xingli and several other professors went out for dinner together to celebrate Zhang Shuo's first lecture to students.

The only difference is that when a large group of professors sat together, the topic they discussed became a seminar on nonlinear partial differential equations.

It was almost nine o'clock after dinner.

Sun Xingli returned to the staff dormitory.

Zhang Shuo returned to the research institute building and temporarily stayed in the luxurious reception room on the third floor. After returning to his room, he lay on the bed, browsed his phone for a while, and soon fell asleep.

What he didn’t know was that just two hours later, a topic titled #Zhang Shuo calculated the winning numbers# made it to the major media pages.

The topic originally originated from a doctoral student at Soochow University named Zhou Chang.

After listening to the lecture, Zhou Chang returned to the dormitory and found that the Mark Six lottery was about to be drawn, so he paid attention to the process.

Then he was surprised to find that the winning numbers of the Mark Six lottery and the numbers written by Zhang Shuo on the blackboard had five or four repeated digits.

If you buy the Mark Six lottery according to the numbers written on the blackboard, you can at least win five fifth prizes and three third prizes.

If you can hit the special number, you might win a second prize!

The second prize should be more than one million, right?
Zhou Chang was so excited that he felt like he had won the lottery himself. He immediately posted a message on Weibo, "Professor Zhang Shuo calculated the winning numbers for this issue of the Mark Six lottery and wrote them publicly on the blackboard!

Photos as proof! "

Below are two photos, one is the numbers on the blackboard and the other is the winning numbers for this period.

Zhou Chang just has a very ordinary account. Few people saw the message he posted, but those who saw it couldn’t help but like, comment and share it.

"Is this true or false?"

"Calculated the winning numbers? Stop kidding, this is a rumor!"

"How is this possible?"

"Maybe it's true, I saw other people saying the same thing..."

Zhou Chang insisted that he did not spread rumors and even asked a lot of classmates to help him.

Many students came forward to confirm the information.

As the news received more attention, the media soon began to repost it, and the relevant public opinion gradually heated up, and slowly became a hot topic...
