Teacher, preach and teach to solve doubts.

The respect for teachers engraved in the bones of Chinese people has always made Chen Muwu regard the matter of attending classes as very sacred.

So invisibly, he put a lot of pressure on himself.

Fowler's words barely gave Chen Muwu a reassurance.

But he suddenly remembered that when he was in college, every summer before the new students enrolled, there would always be various posts on the school's BBS pointing out the course selection, and the seniors of the same department would also spread the word of mouth.

Most of the content is for example, which course is given a loose score, which course is named and attended......

There are also some complaints about the teacher: a certain teacher will only read the courseware on the projection in front of the computer screen in class, and the teacher is full of mistakes in class......

Basically, the vast majority of them are negative evaluations of teachers and professors.

Chen Muwu didn't believe in evil when he was a freshman, so in order to finish the course as soon as possible and continue to play the game, he didn't read the post and blindly selected the teacher of the professional course on the website.

As a result, he met a strange mechanics teacher, not only could he not speak Mandarin clearly, but he spent most of his time in class every time he bragged that he graduated from such and such a school, and went to a foreign school to study for a doctorate, and now he is an editorial board member of such and such a magazine, and next time he is going to run for the head of the department, etc., etc., but he just doesn't give lectures.

In order to pass the exam that semester, Chen Muwu could only borrow notes from classmates in other classes and grit his teeth to read books and study by himself.

Later, after taking the kind of class that is serious and responsible, teaching without class, and in-depth and simple, he realized how important a good teacher is to students.

Chen Muwu decided that he would never use the methods that Fowler taught him until he had no choice but to do so.

He still has to prepare well for this course, to be worthy of the students, and to be worthy of his conscience.

Before the start of the semester, the staff of the Academic Affairs Office of the University of Cambridge sent the list of course selections, and after reading the names of the students who took the course "Linear Algebra", Chen Muwu finally put down his hanging heart completely.

As a time-traveler, Chen Muwu's advantage is not only the knowledge of various disciplines in his brain that is a hundred years ahead of this era, but also the general trend of historical development, as well as the names of some famous people who have appeared or will appear in the future.

These Cambridge students were certainly the most intelligent among those of their age, but Chen Muwu went through his memories and failed to retrieve a famous physicist or mathematician in the future.

In this way, it was very easy to do, and he even felt that he didn't have to go out on his own during the daily Q&A, and it was enough to let Oppenheimer, who had been promoted to assistant coach, go.

There was another thing before the start of the school year, and that was that according to the custom, the professors, teachers, staff, and students of the Cavendish laboratory got together again, and they still borrowed the Bursas Garden, which belonged to the Eucharistic College, and stood on the lawn to take the annual group photo of the laboratory.

Chen Muwu appeared in this photo for the third time, but unlike the previous two times, he sat on a chair in the first row this time.

Behind him stood Oppenheimer, Zhao Zhongyao, Shi Ruwei, and Cockcroft, and Chen Shantou in Cavendis's laboratory had gradually begun to take shape.

Chen Muwu still underestimated his popularity at Cambridge University, and he was too early to rejoice.

There are only about 20 people who take his class, which is not false.

When he walked into the classroom, they were all neatly seated.

However, in addition to these 20 or so students, there were many more people in the classroom who came from other colleges of Cambridge University and did not choose a class but wanted to come to watch the excitement.

Although Dr. Chan is a celebrity at Cambridge University, he is always in sight, spending most of his days in the Cavendish laboratory, not making much public appearances, and his whole person is very mysterious.

Although he had given lectures at the Capitsa Club and the Cavendish Lab before, it was a small area after all.

Now Chen Muwu is finally going to give a lecture at Cambridge University, and the news has been spread by word of mouth, and it has quickly attracted more people to pay attention to this matter.

Standing on the podium, looking at the heads of people under the stage one by one, and saying that it was not nervous, it was fake.

Chen Muwu cheered himself up in his heart, did a lot of psychological construction, and after exhaling deeply, he said the opening remarks that he had prepared a long time ago.

However, everyone only gave him a chance to say the opening remarks.

After introducing himself and the name of the course, Chen Muwu just wanted to talk about the history of linear algebra, so as to quickly cut into the formal content of the course.

He turned around and was about to write the word "history" on the blackboard, but as soon as he wrote the fourth letter, someone in the classroom was already the first to boldly speak: "Dr. Chen, we are not here today to listen to math class, you should talk about something more interesting than math, right?" ”

Hearing what this person said, as well as his rude interruption of his class, Chen Muwu was very angry.

But listening to this person's voice, he felt very familiar.

Chen Muwu still stubbornly finished writing the history this time, he opened his mouth while writing, and then put down the chalk and turned his head, very unhappy from beginning to end: "Sir, you come to audit my class, I welcome you very much." You don't want to hear what I'm saying, and I don't care. But what should be said in class, that's my business, not yours, and if you don't want to hear it, you can get out of the ...... Peter, what kind of trouble are you coming! ”

Seeing the person who spoke, Chen Muwu was angry and happy.

Kapitsa, a Russian guy, didn't stay in Cavendis's laboratory to do experiments, but ran to the classroom to join in the fun!

In order to avoid being detected when he shouted for himself, he also deliberately changed his voice and accent.

If he hadn't turned back in time, he would have really been fooled by him.

"It's not what I personally meant, it's the people who came to this classroom today, and everyone thinks so."

Kapitsa didn't want to apologize for his recklessness just now, but poured the trouble on everyone present.

What's angry is that many people nodded along with him, which can be regarded as a kind of echo to him.

"Don't make a fuss, Mr. Kapitsa, there are so many students in this classroom."

As if he wanted to deliberately oppose him, this time a student raised his hand: "Teacher Chen, we have finished studying the content of your course. ”

Hey, Fowler got it right!

The most basic linear algebra itself is not a difficult course, and Chen Muwu personally even feels that the difficulty of this course is neither the concept nor the theorem, but the huge amount of calculation.

"You're all done teaching yourself?" He asked.

This time, the whole class nodded together.

You are so honest, Mr. Chen can't get off the stage.

After so much hard work compiling lecture notes and preparing for classes for so long, isn't it all useless?

Chen Muwu was still a little uneasy, he randomly ordered a few students, and randomly drew a few after-class exercises, and asked them to give answers to the questions.

Because of the different levels of difficulty of the questions, the time they take to give the answers is also inconsistent.

But no matter how fast or slow, at least the answers were exactly the same as the results that Oppenheimer had calculated for him.

It is said that it is difficult to take classes at university.

However, it is not easy to teach college students.

Especially the University of Cambridge students!

This disappointed Chen Muwu's hope again.

He lectured at Cambridge University, on the one hand, to follow the requirements of Trinity College, and on the other hand, to practice his skills for future lectures.

But who knows, these students have even made the exercises for the last chapter, so what's the point of going on?

It's a pity that this linear algebra course he has been preparing for a long time died as soon as he was born!

It's not realistic, at least for today's first class.

Except for linear algebra, Chen Muwu didn't prepare anything?

Could it be that I have recently made a fun starter, which can produce tens of thousands of volts of high-voltage static electricity, and the market prospect is good, and everyone is welcome to invest?

Let's just throw this problem to the people who raised it!

"Since you don't want to hear linear algebra, what do you want to hear?"

After this question was asked, the audience gave a variety of answers.

Some people want to hear about relativity, some people want to hear quantum mechanics.

There are still people who are interested in the expansion of the universe, could it be that in ancient China, there was really such a Pangu clan with an axe, and with a wave of the big axe, the heaven and the earth were divided into two halves?

Surely there is none!

It's all said to be myths and legends, how can it still be taken seriously?

However, this person's suggestion gave Chen Muwu an idea to kill the rest of the class.

He had previously exported culture with some bad taste, linking the two events of Pangu and the Big Bang.

Then it can be concocted in the same way now, wouldn't it be better to talk about the development of physics in ancient China?

By this time, the Mohist Book of Ink had become an inexhaustible treasure trove.

In middle school physics textbooks, when it comes to the section "Light travels in a straight line", there is always an experiment to image a small hole.

And in the introduction of this experiment, it will also be pointed out that Mozi was the first person in the world to discover this phenomenon.

But when it comes to those official accounts that like to exaggerate the facts, Mozi's exploits have been distorted and amplified by all kinds of bottomless distortions.

It is all nonsense to say that "Mozi discovered the principle of leverage hundreds of years before Archimedes" and "Mozi discovered the essence of force hundreds of years before Newton".

Take the principle of leverage as an example, although the era in which Mozi lived was indeed earlier than Archimedes, the "Book of Ink" recorded that "defeat is not warping, it is said to be winning; At best, it is an experimental phenomenon, not only is it not a complete lever principle, but it also does not give a specific derivation and proof process at all.

Why is "Mozi discovering small hole imaging" written into textbooks, but "Mozi discovering the principle of levers" disappearing from textbooks?

This is precisely because textbooks are very rigorous and do not tolerate the slightest ambiguity.

If we can only observe experimental phenomena and derive the principle behind them, then why not be more bold to say that Neanderthals discovered the principle of levers hundreds of thousands of years before Mozi?

Although it is not advisable to be blind and arrogant, the gimmicks mentioned in these official accounts can allow Chen Muwuhua to use them to bluff people, and he doesn't know what this lesson is going to talk about anyway.

So Chen Muwu's first class at Cambridge University changed from boring linear algebra to the release site of "Violent Theory":

Earlier than Aristotle, he discovered the phenomenon of levers earlier than Archimedes, and earlier than Euclidean defined the circle......

single-handedly, he abused three ancient Greek scientists.

This made Mozi and his book "The Book of Ink" also popular in the classroom, and gradually spread throughout the campus.

Since that day, Chen's linear algebra class has continued according to the schedule schedule.

It's just that what he talks about in class has nothing to do with linear algebra, but is more like "The History of Ancient Science and Technology in China".

In addition to Mozi's "Book of Ink", there is also the starting point of friction in Zhang Hua's "Naturalist".

In addition to these classics, which are barely science books, there are also various idioms and proverbs.

"Pumping from the bottom of the kettle": two conditions for liquid boiling, one is that the temperature reaches the boiling point, and the other is that after reaching the boiling point, the liquid will continue to absorb heat.

"A foot of hammering, half of the day, inexhaustible": is matter infinitely divisible? Democritus said no, Zhuangzi said yes.

Out of respect for a certain elder, Chen Muwu even emphasized the last sentence, and also associated it with the Cavendish laboratory in a grand manner.

"Some people say that atoms are inseparable, but Sir Thomas Sun, the former director of the Cavendish Laboratory, discovered the electrons in the atom.

"Some people say that the nucleus of the atom is inseparable, but my teacher Rutherford discovered the proton in the nucleus and has always believed that in addition to the proton, there is another electroneutral particle in the nucleus.

"Now some people say that protons are the smallest particles, and it is absolutely impossible to continue to divide them.

Is this true or not? I don't think proton can continue to divide, maybe there is something smaller in him. ”

In this way, a few years later, will he Chen Muwu be the first person to predict the existence of quarks again?

The course, called "Linear Algebra", caused more and more repercussions at the University of Cambridge, so much so that during the semester, even the classrooms were changed.

That is, Joseph Needham had graduated from Gwanville and Case College with a Ph.D., and was not in school recently.

If he had audited Chen Muwu's class, he would probably have started thinking about his "Needham problem" decades in advance.

The explosion of Chen Muwu's class also gave Old Tomson some inspiration.

The proposal to establish a new professor at Trinity College was rejected by the review committee.

But if you apply in the name of the Department of Sinology at Cambridge University and let Chen Muwu, a middle-aged Chinese, become a professor of Sinology, will you be able to pass this time?
