The male teacher stood still in front of the podium, and when he saw that Niu Xiaoqiang was still standing, he couldn't help but laugh and ridicule: "This classmate, do you have acne on your buttocks?" If not, please sit down quickly, and if so, please go to the hospital for treatment." ”

The students in the classroom immediately burst into laughter, Niu Xiaoqiang didn't expect a foreign university teacher to talk to the students like this, he couldn't help but bow his head in embarrassment, and quickly walked to a position close to the front row and sat down.

He didn't dare to say that he was here to find someone, otherwise he might be kicked out.

"Let's start the class, today we will talk about the principle of electronic information transmission, please turn the textbook to page 36. ”

There was a loud sound of flipping books in the classroom, and Niu Xiaoqiang had two empty hands, let alone textbooks, not even notebooks. In order not to make himself look too dazzling, he took out a few pieces of waste paper from the desk and put them on the table to pretend, then bent his waist and sat on the chair with his neck bent.

The teacher picked up the chalk and wrote on the blackboard, and after writing, he put down the chalk and patted the chalk ash on his hand: "Since human beings have entered the stage of civilization, the way of information transmission has been constantly evolving and progressing, and now, it has entered the age of electronic information.

The teacher asked a question and glanced around the classroom, but no one raised their hand. He glanced around the classroom again, and quickly took the initiative to point out his troops: "That classmate, do you know the answer to the question?"

The places around Niu Xiaoqiang were empty, and even if he had shrunk up, he seemed out of place with the other students, which was, in Chinese parlance, "one seedling in eight acres of field - a single seedling."

At the beginning, Niu Xiaoqiang didn't realize that the teacher was calling him, he lowered his head and thought about this problem in his mind very seriously.

"This classmate, this is just the beginning of class, should you just fall asleep?"

The teacher seemed to like joking very much, and when he saw Niu Xiaoqiang with his head down and not moving, he couldn't help but smile and took two steps forward and came to Niu Xiaoqiang.

Niu Xiaoqiang felt that the light in front of him was dark, and he looked up a little puzzled, and then he saw the friendly expression of the male teacher.

Niu Xiaoqiang finally understood, and hurriedly explained: "Teacher, I'm not sleeping, I'm thinking about the question you raised. ”

The teacher was just about to speak when he glanced at the scrap of paper on the table. He was stunned for a moment, and then wondered, "...... are you?"

Niu Xiaoqiang hurriedly stretched out his hand to cover the waste paper, and then felt that this was a move to cover his ears and steal the bell, so he retracted his hand in great embarrassment, and said with a dry smile: "I'm sorry, teacher, I came in a hurry today, and my textbook was accidentally forgotten in the taxi." ”

The male teacher seemed very easy-going and had no intention of pursuing it. He sighed and nodded slightly, "Just bring the textbook next time, can you explain your opinion on the question I just raised?"

Niu Xiaoqiang was a little weak-hearted, it was not that he would not answer this question, but he didn't want to attract too much attention, otherwise if his classmates found out that he was not a student in his class, the consequences would be too embarrassing.

"This ......"

Seeing Niu Xiaoqiang stumbling, the male teacher couldn't help but smile and asked, "You are a Chinese student, right?"

Niu Xiaoqiang snorted, and the male teacher sighed: "Why are Chinese students so shy? In fact, you are not worse than others, in my personal opinion, you are much smarter than students from most countries, and the only thing you lack may be courage." ”

As soon as the male teacher said this, some students immediately said unhappily: "Teacher, are you discriminating against us?"

The male teacher smiled and shook his head: "I didn't discriminate against anyone, what I just said is the truth, Chinese students are indeed very smart, not only me, but other teachers also think so." ”

The unhappy student snorted: "Not every Chinese student is smart, right?

This time it was Niu Xiaoqiang's turn to be unhappy, his courage was not small, but he didn't want to attract attention, so he was so low-key.

Most of the time, as long as the other party doesn't go too far, Niu Xiaoqiang doesn't bother to care. After all, this is the United States, and he is new to the country, so there is no need to have conflicts with people.

But this person said that he was a fool, and Niu Xiaoqiang was a little annoyed.

If someone said that about him two years ago, he couldn't refute it at all, because he was really a fool back then, and people just told the truth. As for now, not only is he not stupid, but he is also extremely smart, and he is a genius in the eyes of Professor Watson.

Niu Xiaoqiang was not ready to continue to keep a low profile, he snorted coldly, and turned his head to look at the other party fearlessly: "You are the fool!"

The male teacher saw that the two were about to quarrel, and hurriedly waved his hand: "Okay, okay, there is no point in arguing about who is a fool, if you want to prove yourself, you must come up with real results." ”

Niu Xiaoqiang didn't bother to keep a low profile, he said: "Teacher, I have some thoughts on the question you just raised, can you give me a chance to elaborate?"

The male teacher nodded happily: "No problem, you can explain your point of view without reservation." ”

Niu Xiaoqiang hummed and said eloquently: "In 1948, the mathematician Shannon pointed out in a paper called "The Mathematical Theory of Communication". Information is used to eliminate random indefiniteness', random indefinitability can be described by probability, specifically it is to use information entropy as a measure of uncertainty in the probability distribution, probability itself has inaccuracy, can only be as close as possible to the definite result, in this process, information is a unique form, it is different from the actual matter and energy, there is no fixed model, in a sense, information itself is just the same thing, and this kind of thing cannot be explained by the concept of conventional matter。 ”

As soon as these words were spoken, all the students in the classroom showed puzzled looks, and everyone didn't seem to be able to understand what Niu Xiaoqiang meant.

- Information is a thing, and it is something that cannot be explained by conventional material concepts, isn't that a little too mysterious?

The student who had a conflict with Niu Xiaoqiang just now was the first to speak, and he retorted: "If information cannot be explained by conventional material concepts, then what is the textbook in front of us? Isn't the text in the textbook information? Your answer is obviously problematic!"

This man is right, the words in the textbook do belong to the category of information, and no one can refute this.
