The morning light shone into the large classroom in the east courtyard, casting a layer of glittering golden light on Master Zhao.

His eyes slowly swept across his disciples. After a year of his earnest instruction, they had become the top mathematical talents in the Ming Dynasty.

Next, it’s time to push them to take that crucial step of selling.

Then I heard Teacher Zhao say in a deep voice:

"Over the past three generations, there have been countless sages, each using his own method to understand and explain the world. But so far, including Taixi, all the great scholars on this earth are philosophers."

“Philosophy uses speculation to find the origin and laws of the world. Therefore, every philosopher can put forward his own theory to explain the laws of the universe, but no one can convince anyone else.”

"And science, unlike all philosophy, does not rely on subjective speculation, but mathematics and experiments to find the laws of the world."

After saying this, he continued word by word: "This is the biggest difference between us and others!"

"Yes, Master!" the disciples responded in unison. It was such a great feeling to be so different.

"Why should we use mathematics and experiments to replace speculation? Because among all the subjects, mathematics is the one that can get the clearest and most accurate conclusions. We have all learned Euler's "Elements of Geometry". He derived hundreds of accurate propositions from five postulates. This unparalleled accuracy is in sharp contrast to the ambiguity of philosophers!"

"And one of the two fists of scientific research is mathematics, so it can bring us precise knowledge!"

"The other fist is experiment. Xunzi said, 'If you don't climb a high mountain, you don't know how high the sky is; if you don't stand by a deep stream, you don't know how thick the earth is.' As the saying goes, 'If you don't see or hear something, how can you make a conjecture about its existence?' So although science advocates bold assumptions, it must abandon any subjective conjectures. Because our intuitive judgments are too inaccurate, the only things we can really trust are mathematical calculations and objective experiments!"

"That's why science is so reliable! It allows us to draw conclusions based on scientific methods without having to debate or argue with others!"

"For example, if someone says that the sun, moon and stars revolve around the earth, we can build a telescope and let them see for themselves. For another example, if they don't believe in the existence of gravity, we can calculate it for them!"

"The science is there. Whether you believe it or not, it doesn't affect its correctness!"

"This is why, as a teacher, I have to take the initiative to cut off my relationship with philosophy, because we are fundamentally different. Although I often mention Xunzi's views and do not deny the origins of science and Xunzi, as long as we refine these two fists, we can say goodbye to all philosophy. From now on, we can set up our own school and independently develop countless accurate, practical, and world-changing knowledge!"

"Long live science!" the eldest disciple couldn't help but shout.

Zhao Hao gave him a helpless look, but the other disciples also started shouting.

"Long live science! Master is great!"

That kind of deep admiration almost made Mr. Zhao drunk, and greatly boosted his recently weakened self-confidence.

He scratched his head in confusion and looked at Ma Xianglan who was laughing with her hands covering her mouth. He couldn't understand why his disciples were so excited just as he started talking.

Even when I went to heaven, they were not shocked like this.

The reason why he could not understand the excitement of his disciples was that he was looking back at this period of scientific history from a God's perspective. Naturally, he felt that these things were very simple and were simply taken for granted.

But the disciples who came into contact with these things for the first time were deeply shocked by this epoch-making courage and genius.

~~

After the disciples calmed down, Zhao Hao continued:

"Okay, after solving the 'why', I will teach you the 'how'."

"Yes, Master!" The disciples looked solemn and pious.

"In fact, I have already given you the templates of all scientific research methods." Teacher Zhao said in a deep voice.

"The Elements?" the clever disciples whispered.

"Yes, the most important thing about this book is not how many geometric propositions it proves." Zhao Hao glanced at Hua Shuyang and Wang Dingjue. Yes, I'm talking about you two.

The two beasts have already conquered Chapter 8 and are heading towards Chapter 9...

"It is the axiomatic system established by Ouzi. He gave five basic postulates with great genius, and then derived more than 400 propositions from these five postulates step by step with rigorous logic."

"Because he uses precise mathematical methods, as long as the five postulates are not overturned, all the derived propositions will definitely not have any problems. Ou Zi's scientific system is called an axiomatic system."

"This method of starting from a few most basic and obvious axioms and eventually deriving the entire academic system step by step is the scientific research method that I want to teach you."

Zhao Hao said, his eyes swept over all the students again, and said in a firm tone: "No matter which direction you research in the future, you should do it under the guidance of this method."

"Yes, Master," the disciples responded in a deep voice.

"In order to make you sure, I asked Secretary Ma to copy this book, 'Mathematical Principles of Natural Sciences', and give it to you for study."

Zhao Hao said sorry to Newton in his heart, your epoch-making masterpiece will be attributed to someone else. But thinking that Newton often does this kind of thing, he didn't feel particularly guilty.

I just don’t know, when Niuzi goes to school a hundred years later and reads this book, will he feel particularly familiar with it?

I guess he must have felt this way when he was a kid and learning to use a prism to look at the spectrum?

I hope he doesn't burst into tears.

"This book, Principles of Mathematics in Natural Science, completely follows the method of Geometry's Elements. It first gives a few definitions, then a few laws of motion and rules of reasoning, and then, through a series of reasoning and calculations, it gets some universal conclusions and constructs an axiomatic system of physics."

“Finally, these conclusions are applied to practice and compared with experimental and observational data, which is a complete scientific study of mechanics.”

Then Teacher Zhao calmly used his great incitement technique to incite his disciples:

"I hope that you can use this method to build your own axiomatic scientific system in the future!"

"We remember Master!" The disciples' hearts were beating faster. After following their teacher for a year or so, they finally understood the direction they should go.

Following the different paths opened up by the teacher, we will move forward into different fields and eventually legislate for this subject! We will become the successor of the master in this subject!

Even Secretary Ma couldn't help but feel excited and wondered whether he should also choose a subject and become the young master's successor in the future?

But she quickly dismissed the idea.

Well, compared to being one of the several successors, I prefer being a unique secretary.

ps. Chapter 2, please give me monthly tickets and recommendation tickets~~~
