If a time traveler wants to fundamentally change the times, what should he do most? Import advanced ideas? Exploit black technology? Make a revolution?
None, but the introduction of scientific methodology.
Otherwise, no matter how advanced the ideas are, there will be no place for survival, and no matter how much technology we use, we will only get an alternative rigid system and technology that has come to a standstill.
Scientific methodology is the fundamental method to solve all problems.
Teach people to use scientific methods to look at and solve problems, and if this concept is deeply rooted in people's hearts, countless people will step forward to solve various problems.
New ideas, new technologies, and even revolutions will spring up like mushrooms after a rain.
But scientific methodology cannot be achieved by shouting a few slogans. We must first tell everyone what science is and establish a system, so that this concept can be established.
And this is undoubtedly a complicated and huge project.
The power of an individual is limited. Even if he has the advantage of a prophet, he cannot solve all problems by one person. He must include as many talents as possible.
There are two sources of talent. One is to cultivate it yourself. This is the purpose of writing textbooks.
The second is to find like-minded people. Lu Cai is undoubtedly a person worth winning over, and this is the purpose of his coming here today.
…
Lu Cai was very interested in this physics book, and he was very arrogant in exploring the principles of all things. If someone else had given it to him, he would have definitely thought that the other person was arrogant.
But he didn't think Chen Jingke was such a person. The two had known each other for a while, and he knew exactly what kind of person the other person was.
Since the other party dared to claim to study the principles of all things, he must have some basis for it. He was very curious about what content in this book could make Chen Jingke get the name of physics.
When he opened it, he saw rows of horizontally arranged text. Lu Cai was just not used to it and was not surprised. He had seen the mathematics book brought by Chen Jingke before, and it was also arranged horizontally.
After the introduction of new mathematical symbols and vertical calculation methods, horizontal layout is indeed more suitable.
After simply adapting to the horizontal layout, he quickly got into reading.
Although he was mentally prepared, he was still shocked when he actually read the contents of the book.
Why does the sun rise in the east and set in the west?
Why does the hull of a ship disappear first, and the mast disappears last?
Why does it rain only when there are dark clouds?
Why is there a rainbow after the rain?
Why do apples fall under the tree instead of flying up into the sky?
Why do objects falling from heights become faster and faster?
What shocked him was not these questions. Countless people have raised questions about these questions since ancient times. He himself also had similar questions. There really was nothing to say.
What shocked him was that the answer was actually given in the book.
'The sky is like a chicken's egg, the sun is like a chicken's yellow, the celestial body is round like a bullet and revolves around the sun, and the earth does the same. The earth revolves around the sun from west to east, so the sun rises in the east and sets in the west.'
"Because the ground is like a projectile, as the ship goes away, the hull disappears first, and then the mast disappears."
"Clouds are water mist that condenses into rain."
"Gravity causes the apple to fall to the ground."
"Acceleration of gravity..."
This is a complete subversion of the previous cognitive system, especially the theory of ghosts and gods in religion. It is a direct attack. It can be called a violent theory.
Lu Cai always thought that he was radical enough, but he didn't expect that this real person, despite his age, was far more radical than him.
But for a materialist, not only did he not feel scared, but he was even more excited and couldn't wait to read the following content.
How the earth revolves around the sun, how water circulates, how the acceleration due to gravity is calculated...
What other small hole imaging is behind, what reference objects, what relative speeds...
In short, in this book, Chen Jingke takes common natural phenomena as the starting point and uses the scientific knowledge he learned in his previous life to answer the questions.
It involves subjects such as astronomy, geography, physics, chemistry, biology, etc. It can be said to be a hodgepodge.
But these questions are not just a hammer and a stick. Which question is used and which question is not used, which question comes first and which question comes last, are all carefully considered.
By connecting the answers to these questions, a relatively complete knowledge system can be formed.
For example, rainfall leads to water circulation, which leads to atmospheric circulation, wind, rain, thunder and lightning, etc.
For example, universal gravitation and gravitational acceleration have led to a complete set of basic mechanical theorems and calculation formulas.
From the fact that crops need fertilizer to grow and people need to eat, the concept of elements is derived.
Adding water to quicklime generates heat and turns it into slaked lime, leading to chemical replacement reactions, the law of conservation of energy, etc.
As mentioned before, what he has to do is to establish a framework system. With the system, people can study various problems according to the logic within it.
With the guidance of the system, people can deeply explore the inner connections of things and make breakthroughs in science.
However, considering the practical issues, astronomy is relatively less involved, and this aspect is too sensitive.
He also simply clicked on the theory of day and night to explain the changes in day and night, the four seasons and some common phenomena.
He didn't dare to tell anyone about the eight planets or anything like that. If this thing were to be revealed, Li Shimin would probably explode.
However, astronomy was the least important thing when basic science had not yet been established.
After the basic disciplines were established, even if Chen Jingke didn't do it, there were still scientists who would do the research, so he didn't bother messing around.
…
The above knowledge is actually equivalent to the science level of junior high school, but it was already very advanced for the ancients.
Lu Cai had a hard time reading. He had to consider every question and even every sentence carefully. Even so, he couldn't understand most of them.
But the part he could understand gave him enough inspiration and answered many of his previous questions, which also made him more and more convinced that the content in the book was true.
The more he believed that this knowledge was true, the more he wanted to study it.
Seeing that he was about to get addicted to it, Chen Jingke had to remind him: "Mr. Lu, how about this book?"
Lu Cai raised his head blankly, and then he realized what he was doing. He couldn't help but exclaimed: "It's really... a unique book. How did the real person know this knowledge?"
Chen Jingke smiled and said: "I have another teacher, and later I studied Confucian classics with my master. These were all taught by my original teacher."
Lu Cai asked: "I wonder who the master is and where he lives? I would like to ask for a recommendation from a real person."
Chen Jingke shook his head and said, "They are not in this world."
Lu Cai thought he was no longer alive, so he said regretfully: "My master is really a god. I wish I could ask him for advice in person."
Then he said excitedly: "The real person is also a genius. He can master physics at a young age."
Chen Jingke said: "You think too highly of me. These are actually just the basics of physics. I haven't had time to learn the truly advanced knowledge."
"This..." Lu Cai didn't know what to say. In his opinion, the knowledge was already too deep and couldn't be deeper, but the other party said it was just the basics.
Then how deep his original studies in physics must go, which is very exciting.
Seeing that he took the bait, Chen Jingke slowly revealed his purpose: "Mr. Lu should also be able to see that if this knowledge is used properly, it will benefit the country and the people."
"I have no intention of cherishing it for myself. I want to teach this method to everyone in the world and let everyone in the world study it together."
"In this way, we can not only benefit the world with this method, but also gather the efforts of everyone to study deeper physical knowledge."
Lu Cai said with admiration: "The real person is noble and upright, I admire him."
Chen Jingke continued: "However, Mr. Lu should also know that this theory will not be welcomed by the mainstream, and it will be extremely difficult to promote it."
Lu Cai felt the same way and said: "It is indeed the prejudice of most people to emphasize the study of classics and neglect the investigation of things. If a real person prints and publishes this book, it may be difficult to achieve anything."
Chen Jingke said: "So I plan to take two steps. The first is to make this book public and attract talents who are interested in studying things to join."
"The second is to establish a school in Zixiaoguan to recruit some children from poor families and teach them physics."
"At the same time, physics enthusiasts who come to study can also be placed in the school. We can study physics together and serve as teachers for those students."
Lu Cai said thoughtfully: "This method costs a huge amount of money, and even with the power of Zixiao Guan, I'm afraid it won't last long."
Chen Jingke said confidently: "Money is not a problem. Not only can I meet the funding required for research, but I can also provide everyone with a salary so that they can have no worries and concentrate on studying physics."
Lu Cai saw that he was so confident, so he didn't ask any more questions, but said: "If so, this method is indeed a good method. I would even go there if there was no imperial order."
Chen Jingke looked at the situation and said: "Actually, this is exactly why I came to see you sir today."
Lu Cai said with an embarrassed look on his face: "This...photography shows love to people. Unless I don't want to go, it's really hard to disobey the emperor's order."
Chen Jingke knew what he was thinking. The upright official of Hongwen Hall was now in the eyes of the emperor, and his future was still very good.
It is impossible to leave a good official job and go to Zixiaoguan to become a gentleman.
He is an all-rounder, and studying things is only a small part of all knowledge for him, it is just a hobby.
It is impossible to give up everything else just for your hobbies.
Therefore, Chen Jingke knew before he came that he would refuse, and he also thought of a way to deal with it, saying: "Mr. Lu misunderstood, I am not asking you to resign and join Zixiaoguan Academy."
"The more knowledgeable a person is, the easier it is for him to be arrogant. I am afraid that those who like to study things will despise me because of my age, and thus despise the study of physics."
"So I want to ask you to serve as the college's sacrificial wine. Come over when you have time and help me calm down the situation. Don't worry about the saint, I will go and get his consent."
Having said this, he stood up and saluted him solemnly: "Please give me a helping hand, Mr. Lu."
Lu Cai hurriedly came over to help him and said: "Master, how can I do this? You have a favor with Lu, how can I accept your courtesy?"
Chen Jingke couldn't stand up and said, "Mr. Lu, you will get up if you promise me."
Lu Cai had no choice but to say: "Lv agreed, please hurry up and invite me."
Chen Jingke then stood up and said happily: "With Mr. Lu joining us, this matter is done."
Lu Cai was half helpless, half happy to be valued, and said: "Lv is just a mediocre person, how can a real person be like this?"
"But I can go to the academy to help. Please forgive me for offering wine, but I can't agree to it."
