"How's that, convincing or not?"

Seeing Ji Zhen leave the room and go to the office at the other end to drink tea, Zhao Lao looked at all the researchers in this room and asked loudly.

"Serve! Uppercase clothes! If you don't accept it, you can't do it! ”

Although the clothes in the researcher's mouth are not neat and a little intermittent, the admiration for Ji Zhen is presented on his face.

If they can enter this institute, they are naturally genius-like figures. Although they are above mathematics and physics, they are not confident to compare with Ji Zhen.

However, on top of chemistry, they were still particularly unconvinced by Ji Zhen before.

Even if Zhao Lao said that anti-gravity materials science was transmitted from Ji Zhen, they still didn't believe it, or rather, their emotions didn't want to believe it.

And now, intellectually and emotionally, they are convinced. Mathematics and physics can't be compared, especially above chemistry, either.

also got up from nine-year compulsory education, but Ji Zhen is better than them.

I'm not afraid that people who are better than you work harder than you, but I'm afraid that people who are better than you are younger than you.

Because the latter doesn't just hold you down on the aspect of excellence.

"Let's talk about it, what did you gain from the half-hour that Professor Ji talked about just now?"

Hearing Zhao Lao's question, someone spoke out loud.

"What Professor Ji just said is very extensive and did not explain in detail, but what he said is the key point, straight to the core, and gives us a lot of inspiration."

"Yes," one person spoke, and there were more speeches later, "Professor Ji didn't seem to care about specific theories, and what he explained was basically things in terms of ideas and directions. ”

"Guide our directional path, so that we can use experimental data to overturn those theorems or laws ourselves."

"And, at the end of the day, we have the flexibility to apply theorems or laws, and that's all that matters."

Zhao Lao listened to the words and nodded.

Although there is a big gap between these researchers and Ji Zhen, after Ji Zhen gave them a start and opened a window, they can still follow Ji Zhen's train of thought.

Ji Zhen is equivalent to a pioneer, and they follow.

"In this case, then you should listen to me well, study hard, think carefully, and be sure to thoroughly understand this anti-gravity material science within a year."

Elder Zhao gave a death order!

"Professor Zhao, it's hard for you to do this." The researcher smiled bitterly, "According to our estimated learning progress, coupled with the increasingly in-depth and difficult anti-gravity materials science, there is absolutely no way to do it within a year." ”

Academic knowledge cannot make a great leap forward, if you can, you can't, if you can't, this is determined by IQ.

It's not that the harder you work, the more you get results.

Old Zhao frowned, "How long do you think it will take?" ”

Although I can't be sure, everyone here is at a similar level, and they are self-aware, and they can almost estimate a deadline.

"Estimated for at least three years."

Zhao Lao thought for a while, three years is indeed not a short time. However, he was soon relieved.

Think about the time when you used to overcome difficult problems, a small problem might be stuck in 3 years. It is now a new type of knowledge system of anti-gravity materials science, which only takes three years.

It's been soon!

Thinking of this, Zhao Lao's mood also changed, and he said, "Okay, then I'll give you three years." ”

After a while, Ji Zhen returned to this room again and continued to explain.

···

Three hours later.

Ji Zhen was sent out of the door of the institute by Zhao Lao.

"Xiao Ji, I have a sentence, I don't know whether to say it or not." Zhao Lao looked at Ji Zhen's face and said.

Ji Zhen couldn't cry or laugh, "You said." ”

When the elders say this kind of thing, they are humble, indicating that what they want to say is still important, and they can't say it directly, so there is such a buffer.

If Ji Zhen directly scolded him, then there was no need to talk about it. That's obviously rude.

Zhao Lao is not a young man, but a senior, and Ji Zhen still maintains enough respect as a junior.

Without the overcoming of these predecessors, there would be no good life now.

"Have you ever thought about doing an open class?"

Ji Zhen was stunned, "Open class? ”

Elder Zhao nodded, "Your current academic ability, mathematics, physics, and chemistry are all top-notch. And you are not very old, and in the hearts of young people, you have a very big influence. ”

"I also know that you have a heavy task now, mathematical research, physical research, anti-gravity technology research, and now you have more work on anti-gravity materials science. So, now your teaching assignment has been canceled. ”

"But can you make some time each week? Record a two-hour public lecture and distribute it online so that other people who love to learn, or who don't have enough resources, can also access this knowledge. ”

Ji Zhen listened carefully to Zhao Lao's three words, and pondered for a moment, "I will consider it carefully." ”

Zhao Lao nodded, "The world belongs to you young people. We have a population of 1.4 billion in China, and education is in place, and it is not a very difficult thing for the Celestial Empire to be in history back then. ”

At present, although the country's education has basically eliminated illiteracy, it is still a little worse than the high-end field.

And this part is one of the reasons that determine the strength of the country.

Zhao Lao's idea is to use Ji Zhen's influence, coupled with Ji Zhen's own extraordinary knowledge, to give people more opportunities.

For example, students who like mathematics, but did not get into Yenching University because of serious deviations. They can learn more advanced mathematics from Ji Zhen's open class.

In terms of mathematics, Professor Ji Zhenji is definitely the top level in the world.

Isn't it more attractive to have a local professor, Ji Zhen, who speaks the local language to explain mathematics knowledge than a foreign open class?

···

Back at home, Ji Zhen sat on the sofa and began to think about what Zhao Lao said about opening an open class.

I don't know who said it, maybe it was Lu Xun.

Everyone has a good psychology of being a teacher.

At least, standing on the podium, Ji Zhen gave lectures to students, which really made him very intoxicated and found it quite interesting.

As he got more and more tasks, he pushed the lecture away. After all, there are still a lot of courses for teaching tasks.

However, the idea of an open class that Mr. Zhao is proposing now is a sight to behold.

An open class is not the same as a teaching task because it has no limits. You can talk about whatever you want.

The teaching task should take into account the flow of the textbook, and it is impossible to choose one of them for in-depth.

However, open classes are possible.

And as Zhao Lao said, it is also a good idea to spend a little time every week recording public lectures and releasing them in the form of serialization.

It doesn't have much impact on Ji Zhen, and he can still spread knowledge.

Thinking of this, Ji Zhen decided to open an open class.

He took out his mobile phone and made a call to the dean of the School of Mathematics, informing him of the incident and asking the department to get ready.

Of course, the school supports Ji Zhen's idea of opening an open class.

After hanging up the phone, Ji Zhen took out a pen and paper and began to write and draw.

Open classes are not held casually, and the first thing we face is the problem of topic selection.

"The first season can't be too profound, it's best to go from shallow to deep."

And, of course, the first thing to open is the mathematical classification. In the future, there will be open classes in physics, chemistry and even computer science.

In terms of topic selection, Ji Zhen pondered for fifteen minutes before finally deciding.

Vector and multivariable calculus!

This is what Ji Zhen has chosen.

It is a calculus course in the second semester of the first year, and it is a compulsory course for undergraduates of many departments at Yenching University.

Topics include vectors and matrices, partial derivatives, double and triple integrals, plane and space calculus.

After writing down these general categories, Ji Zhen is ready to subdivide them further.

"What are you doing?"

I don't know when, Xu Linfei came to Ji Zhen's side, looked at Ji Zhen holding a pen and writing special mathematical terms on paper, and asked curiously.

Ji Zhen's thoughts at this time have been clear, but he is not worried that Xu Linfei will interrupt his thinking.

He turned his head, looked at Xu Linfei, and said with a smile: "I want to do an open class, this is the content of my first season of open class." ”

"Doing an open class?"

Xu Linfei's eyes widened, this was really a bit unexpected. "Why did you suddenly think of doing an open class?"

"I went to the institute today, and I found that the researchers' knowledge was still a little worse. It just so happens that I am quite successful in many aspects, so I will do my part to allow more people to receive more comprehensive and in-depth knowledge. ”

"After all, a lot of the time, I'm still a little slower when I'm alone."

Xu Linfei knew that this was cultivating talents, but Ji Zhen was using open classes to cultivate.

"Okay, I'll support you anyway."

Ji Zhen smiled and didn't say anything, everything was in his heart.

"I'm going to buy you some fruit, and you can think about how to do this open class!"

Ji Zhen nodded, and when Xu Linfei was about to go out, he suddenly shouted: "Don't buy oranges!" ”

Xu Linfei was stunned for a moment, and then a sanitary eye flew towards Ji Zhen, "Just your skin!" ”

She pushed the door open and walked out, halfway down the road, pulling out her phone.

opened Weibo, and then posted a text with a picture of Ji Zhen thinking seriously.

There are a lot of pictures like this in her mobile phone.

"Professor Ji is going to give an open class, and I'm looking forward to it...

Xu Linfei's Weibo, Ji Zhen didn't know that he was now sorting out the content to be taught in the first season of the open class.

"Matrix, inverse matrix; Second-order guide test: boundary and infinity; Differentiation, chain rule; Lagrangian multiplier method; line integration of plane vector fields; gradient fields and potential functions; divergence theorem; Stokes' theorem; Topological Thinking - Maxwell's Equations. ”

Ji Zhen wrote down the content to be explained on paper line by line, using this as a catalog, and then refined and sorted.
