Something that resonates for thousands of years without having to meet, nothing is better than culture. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

At this time, Chen Jian was far away in Tamsui River, Taiwan, to learn the indigenous language, and Xu Guangqi was worried about the Shanghai system, but relying on the names of angles, straight lines, obtuse angles, and acute angles, the relationship between the two was brought closer almost within a few days.

Xu Guangqi struggled to explain this familiar feeling, and a year earlier he had translated the first six volumes of the original geometry, giving these names such as obtuse geometry without any references.

At this time, the book was still around and had not been published, but the book that had been handed down in the Far South had the same name.

It's like someone you've never met, but you read your own heart.

This is the fetters of culture, a fetters that can be read in a thousand years and still be catchy in a tone that can be read in a tone that has long since changed, and a fetter that can cry or laugh out loud when reading the words of history in a tone that has long since changed.

If there was no Xu Guangqi, there would have been geometry.

But in that case, it is unknown whether geometry is called geometry, and whether an obtuse angle is an obtuse angle is also an open case. Geometry is the name of geometry but not geometry itself, and obtuse angles, if named acute angles, are still obtuse angles but are no longer obtuse.

It was Xu Guangqi who helped Chen Jian translate these things without racking his brains, and Chen Jian fed back to Xu Guangqi without knowing it, and this kind of similarity of thoughts is a tacit understanding that is difficult to explain in words.

This book of arithmetic and geometry is the perfect book conceived in Xu Guangqi's heart, as a person who is subject to the times and wants to transcend the times, he must be the elite at this time, the existence of one out of ten thousand.

Therefore, when he began to translate Geometry, Xu Guangqi wanted not only to translate, but also to establish a mathematical system, a mathematical system with logic.

Algorithm is the technique, and logic is the way.

However, Matteo Ricci wanted to translate the astronomical calendar to please higher officials such as the emperor, and his purpose was to preach, and Xu Guangqi returned to his hometown after his father died after translating the first six volumes...... If everything is normal, by the time he returns to the capital, Matteo Ricci has already died, and the remaining missionaries have no such mind or talent, and they will leave half a book after all.

The easiest bait to take the bait is often what you want most in your heart, as if you are reflected in a mirror that you don't even know yourself.

Looking at the translations that were too familiar to be familiar with, except for a small number of translations such as isosceles triangles, which were slightly different but could be understood after thinking about it, Xu Guangqi understood that what he had been wanting could finally have a second choice.

At this time, Xu Guangqi was still in contradiction, he had not yet completed the ideology of the unity of Confucianism in his heart, but in these books, he saw another word called "Dao" that appeared many times and he was very familiar with.

This path may not be the other way, but it allowed Xu Guangqi to open the door to a new world, and the shock in his heart was no less than when he first came into contact with the missionary and saw the original geometry.

Different paths lead to the same end, and the road is one...... Vaguely, he had a trace of such an idea, but he couldn't grasp where this idea came from.

What he liked most of these books was the translation of the name "Science", which coincided with many things in his mind, but those were only germinations and did not systematically form a complete idea in his heart.

When translating European hydraulic engineering monographs, Xu Guangqi vaguely felt that the techniques of these Europeans were "based on measurement and calculation", and the remaining technologies and machinery were secondary.

And the translation of science used by Chen Jian is exactly in line with Xu Guangqi's thoughts at this time. This is the Dao, and those mechanical and the like are the techniques that arise from the Dao.

This wonderful coincidence and identification made Xu Guangqi a little trance, and the familiarity that arose from his mind and flowed back into his mind made him feel an inexplicable closeness.

In fact, he is close to himself, and he is also the easiest person to get close to, but Chen Jian put his skin in his book without his knowledge and changed his name.

A few days later, he put down the books and invited the mysterious guests, wanting to ask for something more.

Looking at the young man sitting here, he was surprised by the young man of the other party, so he picked up "Arithmetic and Geometry" and asked, "This book will definitely shine in the future, everyone can read it, everyone must read it." I don't know how many people read this book in your state? ”

The young people have also read the content of the book, although the words are different, but some of the formulas in it can be seen at a glance, and they nodded: "According to what you said about the imperial examination...... Our imperial examination is also to be examined. Arithmetic is also a compulsory subject. It can't be said that everyone must read it, but there are still quite a few people who read it. After reading this book, you can calculate money and grain, dig river embankments, and build fortresses. However, Mr. Chen's writing is very deep, and some things are actually only circulated among a small number of people. ”

Xu Guangqi sighed lightly, he had heard that this "Mr. Chen" was not yet old, but he was only honored by his knowledge, and he heard the faint respect in this person's tone, and smiled: "Presumably, the Mr. Chen you mentioned must also be an erudite and talented, but it's a pity that he is on the side." Now I am at home, and even if he goes to the capital to discuss trade, it will be within two years. When I entered Beijing, I was afraid that he would have already returned to China. ”

The young man thought about some of Jian Chen's instructions, and hurriedly said: "If you are a god with science, why should you care if you meet or not?" This time, Mr. Chen actually had something to ask for. ”

After a pause, he said, "Mr. Chen said that science is universal for everyone. And the more people who study, the more results can be achieved. Morality aside, future generations always know more than their predecessors in this kind of thing, which does not vary from country to country, depending on the environment, seasons. Therefore, he hoped that with the help of Mr. Xuan'an, he could establish some schools to teach this scientific method. Only when there are more people who learn and communicate with each other can they continue to improve. ”

Xu Guangqi hurriedly said: "This is a good thing for the benefit of the country and the people, and I will not shirk if I can." It's just that...... I am shy in my pocket, and the house in Shanghai County is a place for preaching doctrine......"

The young man laughed and said, "Mr. Xuan'an, don't worry, Mr. Chen is also a first-class capitalist in my country, and money is not a problem." ”

The word capital is easy to understand, and the original meaning of the word capital is mostly used in the Song Dynasty scripts, and the Ming Dynasty has long been circulated.

The word capital in front and the word family in the back are nothing more than two meanings. Either they are people who make a living from the profits of capital, or they are schools of thought such as Confucianism.

After thinking about it for a while, Xu Guangqi understood what this person meant by capitalists, so he naturally took the previous intention, because he smiled and said: "I didn't expect that it turned out to be a rich family with a lot of land. ”

"There is not much land, and the main thing is to make money from scientific profits. The mirrors, glass, and oil lamps that were given to Mr. Hyun An were all Mr. Chen's property. Now in the country, everyone in several counties knows about it. Therefore, for things like building a school, Mr. Chen naturally paid for it, which can be assured. The main thing is to ask Mr. Gen-an to find some young talents who are interested in science, and this is where he wants to ask Mr. Gen-an for help. ”

Taking the opportunity to tell some stories about Chen Jian's "self-made" in Fujian, and also about some things such as relieving disaster victims in Quanzhou and calculating comet earthquakes, Xu Guangqi was fascinated by it and couldn't help asking: "Do you know about astronomy and the universe?" ”

The young man glanced at the disciple of Mr. Benchu who was proficient in astronomy and mathematics that Jian Chen had prepared in Mincheng as early as in Mincheng, and secretly glanced at him, and instead of speaking directly, he asked, "What does Mr. Xuan'an think the universe is?" Can the universe and the universe be separated? Can time exist independently of space? ”

Xu Guangqi laughed and said, "How can these profound words be said clearly in three words? In the future, if you have the opportunity, you can sit down and talk slowly, and today I will just talk about the comet, astronomy, solar and lunar eclipses. ”

Before coming, Jian Chen had already told them this question, this is a breakthrough, but it is extremely difficult to open this breakthrough.

Even though Xu Guangqi was the first scholar to come into contact with European astronomy, he was exposed to geocentrism rather than heliocentrism.

On the one hand, there is the ideology of Catholicism, which is extremely conservative.

From the point of view of heliocentrism alone, the burning of Bruno was not because of heliocentrism, but because Bruno sprayed from Mary to God and then to Catholicism, and after spraying Catholicism, Calvin and Luther were sprayed. After spraying these people, they were not satisfied, and they also put forward slogans to nationalize the land of the church, close the monasteries, let the priests serve the people, and so on. Dare to shout like this, the death of eight years ago is inevitable, but on the whole, heliocentrism has not made too many waves.

On the other hand, when Chen Jian calculated the time and Matteo Ricci came to China, geocentrism had the absolute upper hand, and even from a "scientific" point of view, it could never be heliocentrism.

This was basically the case until he went to sea, and before that heliocentrism was just a guess in Europe, and even mathematically verifying it was wrong.

Two things are needed to break this speculation.

The first is the astronomical telescope.

Jupiter's moons were observed to prove that the Earth is not the center of the universe and that there is another system outside of the Earth. If the Earth is the center of the universe, then the Moon, the Sun, Jupiter, and any other planet revolve around the Earth.

As long as it can be shown that there is one thing that does not revolve around the earth, the most basic perfect model of this hypothesis is broken. Jupiter's moon is the best choice because it doesn't orbit the Earth and is easy to observe.

But the role of astronomical telescopes is only to break this perfect model, not to completely overturn geocentrism. It even needs to be corrected a little, and you can continue to explain it from the center of gravity.

Therefore, a second thing called mathematics is needed, relying on observation to calculate the ellipse trajectory of the star, with the upper plane Cartesian coordinate system and simple calculus to solve the ellipse problem.

Without the elliptic theorem and the calculation of the focus and eccentricity of the ellipse, many heliocentric hypotheses are wrong to extrapolate mathematically from the standard circle trajectory.

Thankfully, these two things aren't a problem.

The former, Chen Jian, is spending money to manufacture in Mincheng.

The latter saw the first astronomical treatise of the academy in his life about the eccentricity of the luminous star, and the elementary calculus and Cartesian coordinate system had a prototype, he had read that article for ten years, and he had also seen the gentleman who wrote the article, and the name of the old gentleman became the name of the meridian, and the disciple also followed Chen Jian to the sea to the Ming Dynasty......

In addition, the group that started with the hypothesis has always believed in heliocentrism, so the eccentric rate event only affects the world's "cosmology compulsive patients with symmetrical circle aesthetics" and does not affect the model of the universe.

Hypotheses are hypotheses, heliocentrism can explain many things, but geocentrism can also explain.

Therefore, if you want to make this hypothesis acceptable to people like Xu Guangqi, who have accepted the perfect geocentric theory, you need to prepare several years in advance.

The problem now is that Chen Jian has relied on his fame and connections to recruit the best astronomy and mathematical talents among the younger generation of the group, but if he wants to explain it clearly, Xu Guangqi needs to help him polish "Arithmetic and Geometry" first, and be able to understand some calculation methods of the principles of ellipses and triangles.

It's like a strange circle, if you want to eat steamed bread, you need to plant wheat first, and you have to eat steamed bread to survive to grow wheat......
