********************************************

School life passed very quickly, a day, a few classes, passed in an instant, and he didn't feel anything at all, but Han Feng's time was all spent in the library, and in the past few days, he didn't go to any professional classes, and he was all stilted. In this regard, Xu Linhu and Li Wang were full of admiration, of course, the two of them also persuaded Han Feng not to relax on himself, but after learning that he was studying on his own in the library, they let him go, after all, everyone has their own learning methods.

The teacher almost didn't name him, but for some reason, two days later they all knew the fact of Han Feng's class, some teachers just mentioned it, and didn't care, and some teachers couldn't tolerate it, and then every day before class, Han Feng's name must be called, and every time he was not there, this can make these teachers angry, and unanimously reflected the situation to the counselor Dai Xingjian, and said, if you don't come to class again, then Han Feng's usual score is equal to zero eggs.

For this reason, the counselor specially found Han Feng to talk, this is the first student he has found to talk to since the beginning of school, last time for the problem of staying outside, he was a headache by Han Feng, of course, in the end, Han Feng still compromised, obeyed his arrangement, but this time, Han Feng just didn't go in, no matter what he said, he just didn't plan to go to class, said he wanted to study by himself.

The purpose of Mizuki University is to promote individuality, encourage independent thinking, how students learn, usually the school does not care much, older students do not go to class, there are many examples, but it has always been rare among freshmen, so, for the situation of Han Feng, Dai Xingjian has no way, did a period of ideological work, he left, but in his heart he completely labeled Han Feng as a "problem student".

In the past, Han Feng got up very late, because every night when there was no one on the playground, he would go to the playground to exercise, making himself physically and mentally exhausted, and after taking a shower, he would go to bed, and the next day he would sleep at least until about ten o'clock.

However, today, Han Feng got up early in the morning, and this time he did not go straight to the library, but went to the teaching area of the Department of Neuroscience, because there was a neurology course taught by Professor Li Zhongwen today.

When he arrived at the classroom, there were still ten minutes before the start time, and there were already some students in the classroom, and after Han Feng entered the door, he found that several people were staring at him suspiciously.

Han Feng knew what was going on, because there was only one class in the Department of Neuroscience, and there were still very few classmates in this class, so they were naturally familiar with each other, and now that his face appeared, it would naturally cause them some doubts and curiosity, but he didn't care, it was normal for him to go to a class in another department in the university to listen to lectures.

Casually found a seat in the back, Han Feng sat down, then took out the neurosurgery textbook and began to read.

The neurology textbook he held in his hand, the editor-in-chief of which was Professor Li Zhongwen, although the content in it seemed very general and did not tell too many details, but in Han Feng's view, it had been of great help to him, and many problems he had encountered before, but he had solved them with his own observations and feelings, and did not have a systematic and comprehensive understanding. Now that he has read this textbook compiled by Li Zhongwen, Han Feng has a feeling of sudden enlightenment, and when he sees the wonderful points, Han Feng will have a knowing smile on his face.

Han Feng's way of reading, he didn't think there was anything wrong with it, but in the eyes of others, his behavior was a little abnormal.

Seven or eight meters behind Han Feng's right, a girl was looking at him with a slight frown, if Han Feng turned his head, he would definitely find that this girl was the girl he saw in the library who almost put him into a state of death.

After a while, the class Ling rang.

Seeing Professor Li Zhongwen walk into the classroom, Han Feng closed his textbook and prepared to listen to his class intently to see if his class was really as good as everyone had rumored, so as to decide whether to continue listening in the future.

Facts have proved that Professor Li Zhongwen's class is vivid and interesting, and he can express some more complex concepts in very vivid language, so that everyone can easily accept them. He doesn't have to read the lesson plan, he knows what he wants to talk about, and he often draws inferences between them, interspersed with a lot of content outside of the course, even if you have a deep understanding of the textbook in advance, you can still gain a lot...... Listening to his lectures, it is easy to lose track of time, and you will involuntarily follow his rhythm to think and laugh.

After only listening for ten minutes, Han Feng had already included his class in the scope of must-take.

Perhaps, among the many students, only Han Feng can truly appreciate the breadth of Professor Li Zhongwen's knowledge, truly understand every word he says, and correspond his words to the actual situation in his body.

Listening all the way, Han Feng has been following Professor Li Zhongwen's step-by-step thinking, and solved many problems that he couldn't figure out before.

However, although Han Feng listened carefully and understood very deeply, he was the only one in the class who did not take notes. As for the other students, in the face of Professor Li Zhongwen's profound teaching, the pen in their hands has never stopped.

This special situation of Han Feng was noticed by Professor Li Zhongwen.

So, after teaching a paragraph, he stopped, pointed in the direction of Han Feng with his pen from afar, and asked, "This classmate, do you have any questions? You don't have to be restrained, if you have any questions, you can interrupt my lecture at any time, raise them, and then we can solve them together." ”

Suddenly, all the students' eyes were focused on Han Feng.

Although the incident happened suddenly, Han Feng didn't panic much, but stood up very calmly, and picked a problem that had been bothering him in a hurry:" According to the molecular biology theory described in the textbook, the impulse on the nerve fiber is an electrical impulse that lasts for one thousandth, which is the conclusion reached by the winners of the Nobel Prize in Physiology or Medicine in 1963, and it is also a conclusion that is generally accepted. Mr. Li, my question is, does this mean that a nerve impulse is not just an electrical impulse?"

“……”

Quiet –

At this moment, the entire classroom was suddenly silently dropped a needle on the ground, and it could be heard.

All the students showed puzzled and confused looks on their faces or eyes, with their current level of knowledge, they couldn't understand what Han Feng was talking about.

Professor Li Zhongwen was obviously surprised, he really did not expect that this student would be able to ask such a deep question, and the question was closely related to what he had just explained, and it was not that he had to have a high level of knowledge to ask it, but it required the questioner to dabble in a wide range of sciences and be able to think positively.

After being stunned for a moment, Professor Li Zhongwen came back to his senses, nodded with a smile, and said, "This classmate, please sit down, can you tell me your name?"

"Korean style. ”

"Han Feng?" Professor Li Zhongwen read it again, but he didn't have much impression of the name in his mind, and then he continued, "In my class in the future, if you ask any questions, you don't need to stand up, just sit in your seat." When we are studying, we should think positively, not always passively accept, but diverge our thinking......

"Maybe many students didn't hear Han Feng's question clearly just now, so I'll explain it in detail. The 1963 Nobel Prize in Physiology or Medicine was awarded to three scientists working on the fundamental processes of neural control mechanisms and connections between nerve cells: Sir Eccles, Professor Hodgkin, and Professor Huxley, who concluded that a nerve impulse is an electrical impulse in which nerves are "pre-packaged" In the nerve membrane, which is made up of fluids and proteins, charged salt particles can pass through the particle channels within the membrane, and the pulses are transmitted from the end of one nerve to another with the help of charged salt particles. However, as Han Feng said, this conclusion contradicts the conclusion of the laws of thermodynamics, and experiments have proved that nerve impulse conduction does not produce heat......"

“…… Han Feng may not have realized that he just asked a world problem, a problem that has plagued scientists all over the world for more than 50 years, yes, this problem has not been solved yet, and coincidentally, this problem is one of the topics I have been studying. You can discuss it, and then express your opinion, don't worry about saying it wrong, this is a world problem, no one will laugh at you, perhaps, the conclusion you said today is exactly the right conclusion. Professor Li Zhongwen did not directly state his own opinions, but let everyone express their opinions.

Just ask a random question about the world?

Han Feng felt very helpless, he was just in a hurry, and casually picked a question that he couldn't usually figure out to meet the situation, but he didn't expect it to be like this, he would have known this, he wouldn't have asked.

The students in the class were only a little surprised, but when they heard Professor Li Zhongwen say this, they immediately started to talk about it.

"Damn, this is also a problem in the world? I've thought about it before, but I just didn't say it. A boy said sourly.

"Does electric transfer necessarily produce heat?" asked the other students.

"Anything but electrical impulses can be conducted so fast?"

"Is he the same Han Feng? ...... so powerful."

“…… It doesn't matter if he's an electrical impulse or not, is it necessary to figure it out so clearly?"

……

So, everyone said a word, and the class ended in this discussion, and naturally, the problems that have plagued scientists all over the world for decades have not been discussed so easily.

When Professor Li Zhongwen left, one of the students asked, "Mr. Li, this is the topic you are currently studying, have you come to any conclusions?"

Professor Li Zhongwen looked at Han Feng, and then said with a smile: "My point of view is the same as that of Han Feng, a nerve impulse is not just an electrical impulse. However, the current research is limited to this, and further experiments and observations are needed. ”
