"As for this book, Principles of Mathematics of Natural Sciences, there is almost no reading difficulty for those who have mastered geometric methods. The only additional knowledge that needs to be learned is the knowledge of conic sections. These two aspects are explained in the first chapter of the first part of this book, which are the mathematical foundation of the whole book."

"And to make it easier for you to understand, this book tries to avoid using the more difficult calculus methods and strictly limits the mathematical tools to geometry." Teacher Zhao said in a deep voice: "So I will only focus on explaining the knowledge in the first chapter of the first volume to you. I believe you can understand the rest through self-study."

The disciples then understood that the master's words "Those who do not understand geometry should not seek to be his disciple" were not simply the scientists' pride, but because if they wanted to further study science, they would not be able to do so without geometry as a foundation!

As for self-study, the disciples have long been accustomed to the style of "the master leads the way, and the learning is up to the individual". If the master breaks it down and explains it, they will feel uncomfortable.

That means the master looks down on them and thinks they don't have strong learning ability and insufficient comprehension, so he has to break it up and mash it up before feeding it to them.

This is a huge shame for scientists who claim to be geniuses...

~~

Then Mr. Zhao spent only one morning explaining the eleven lemmas in the first chapter of the first volume, and asked Secretary Ma to give him a copy of "Theory of Conic Sections" by Mei Zi, a disciple of Ou Zi... Those were knowledge from more than two thousand years ago, and they would definitely not be difficult for the disciples who had already learned geometry.

This ended this short but extremely important lesson.

All the remaining chapters were taught by themselves by the extremely capable disciples.

But Zhao Hao was not just being lazy, it was also because this huge book was not suitable to be used as a teaching material...

Because in Newton's time, firstly, mathematical tools were very limited, and secondly, algebra had not yet been widely accepted by the public.

So although Lord Niu had already mastered calculus, he chose not to use it, and insisted on using pure geometric methods to complete all his proofs.

Therefore, if we talk about it purely from the perspective of learning knowledge, it is better to directly give the high school mechanics textbooks and calculus to the students.

But as Zhao Hao commented on "Elements of Geometry", the greatest significance of "Mathematical Principles of Natural Sciences" is not the process of deriving those propositions, but its rigorous scientific research method!

As long as the disciples are willing to read this book carefully and engrave the scientific research methods into their bones, this great work will play its due role.

If we guide them to use analytic geometry and calculus to prove these propositions right from the start, they will be unable to master the most valuable things.

As a professor of later generations said, it is useless to learn higher knowledge in order to learn a part of knowledge well.

This is like learning some algebraic methods in college in order to solve high school geometry problems. You can solve them, but you lose the opportunity to understand this part of geometry knowledge.

So let's take it step by step.

I have advanced human science by one hundred and twenty years. That's already great, okay?

~~

After class, Zhao Hao stopped Li Maocai and Chen Yubi, who were planning to go home, and asked them to have lunch with him.

He also instructed Zhang Jian and Zhao Shizhen to go to Shenjiying again in the afternoon to teach them how to make hot air balloons.

"Bring back the three generals along the way." Zhao Hao specifically reminded the two, "Remember, be respectful to them."

He estimated that the three generals must be in a bad mood now. These two guys were cold-faced, stern-mouthed and emotionless scientists. If he didn't warn them in advance, things might get unpleasant.

"Yes, Master." Zhang Jian nodded, and hurried away with Zhao Shizhen.

"Let's go and have dinner." Zhao Hao called Li and Chen.

"Yes, teacher." The two of them quickly responded and followed Zhao Hao back to the west courtyard.

Both of them called Zhao Hao "Teacher", while Yangyang and even Bei Peijia called him "Master".

It's not that you two are being pretentious, but they haven't formally kowtowed to become my disciples, so they are not qualified to call me master.

After all, the Science Institute is an organization with pyramid scheme characteristics... Cross out the previous sentence and change it to "rigorous scientific institution".

How can it be possible without a hierarchy?

Of course, Mr. Zhao would never admit that he was involved in pyramid selling. He claimed that the purpose of doing so was to better teach students in accordance with their aptitude and to motivate his disciples to keep making progress...

Well, with this explanation, it feels much more high-end.

In this organization, which is written as "science" and called "MLM", there are five levels in total.

The two gentlemen and the thirty or so students accepted by Zhao Hao are all in a teacher-student relationship with him, and are called "science students" in the science field.

Science students are at the lowest level in the five-level system and are not qualified to call Zhao Hao "master". They can only call Zhao Hao "teacher".

Only if they have achieved academic success... to put it bluntly, if they have passed the imperial examination, or demonstrated scientific expertise in some area, will they be accepted as Zhao Hao's 'registered disciples'.

Currently, there is only one registered disciple, Bei Peijia. The registered disciples can now call him Master. But the Master will not teach students in accordance with their aptitude. They can only attend the big classes and learn by themselves.

Registered disciples need to wait until they have made achievements... to put it bluntly, they need to pass the imperial examination or have outstanding achievements in science before they can be promoted to "in-house disciples" and receive a name from the master.

Currently, Zhao Hao has seven formal disciples.

Actually, Yu Shensi is not qualified... Although Zhang Jian is only a student, he has already made several inventions. The drainage king alone is enough to accumulate enough contribution points.

But Lieyangzi came early, and at that time Zhao Hao had not yet thought of grading his disciples.

At that time, not counting the Yu brothers, Master Zhao only had three disciples, so how could he think so far ahead? So Yu Shensi took advantage of him.

In addition, this child was very stubborn, so Zhao Hao didn't have the heart to take back the title he had given him... But deep down, Master Zhao couldn't help but be unhappy with him.

It’s like the feeling of a class teacher looking after a poor student.

Finally, there is a higher honorary title above the disciples, called "successor of the mantle", also known as "direct disciple".

That is prepared for those disciples who are the leaders in a certain subject, and no one has got it yet.

~~

Don’t blame Mr. Zhao for engaging in pyramid schemes. Anyway, this method seems to be very effective at the moment.

The most direct manifestation is that the two cabinet ministers are almost dying of inferiority complex...

When it was time to eat, Zhao Hao asked them to get on the kang, but the two young masters insisted on eating while standing on the edge of the kang.

This made Zhao Hao feel very upset, thinking to himself, the Southern School of MLM is really terrifying, even a young cabinet minister is about to lose himself.

So he decided to be nice to the two of them, so he picked up a chicken leg for each of them and asked them in a friendly manner, "How do you feel about your first class?"

Who would have thought that it would have been fine if he hadn't asked, but his direct questions made the two of them unable to eat.

Li Maocai's tears dropped into the bowl, he shook his head and was unable to speak.

Chen Yubi felt a little better, and said with red eyes: "I didn't realize it at first, but after these two days, I realized that I am so far behind others."

"Yes, other people scored 120, and the two of us combined only scored that much." Li Maocai wiped his tears and said, "And the textbooks the teacher gave me look like incomprehensible books to me."

"Students are the same." Chen Yubi nodded and choked up, "If we continue to stay in the dark, we will only bring shame to the teacher."

"Yes, teacher, we are too embarrassed to fill in the gaps." Li Maocai was almost snotting.

"Don't talk nonsense!" Young Master Zhao was so anxious. If you two leave, I will suffer a great loss! !

“You guys are excellent!”
