Time flies, it is autumn and winter when the Tamsui River separates, and it is a new year in the blink of an eye. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

In the thirty-sixth year of Wanli, Xu Guangqi, who was worried about Ding, returned to Shanghai to defend the system.

His courtyard in Shanghai County had become a Chinese-style church, and the Jesuit priest Guo Jujing used it as a basis for his attempts to preach the doctrine in Shanghai and attract believers. This Italian not only has a Chinese name, but also a number, known as Yangfeng Jushi, and his level is still very high.

At this time, Xu Guangqi had been baptized and his Christian name was Paul.

During the Ding period, he did not live in a house in the county seat, but bought some land elsewhere to do some cropping work, and in his spare time pondered the Pythagorean theorem and measurement techniques.

Occasionally, he would teach arithmetic and science to some local young people in the county, and one of the young people was named Sun Yuanhua, who was gifted and curious, especially like mathematics and geometry, so he regarded himself as a disciple and was not baptized.

On this day, several strange guests came to Shanghai County, holding a letter from the prefect of Quanzhou, and no one dared to stop them.

Among these strange guests, the first is Chen Jian's supporters, and it is okay to say that they are admirers. At a young age, he is considered a disciple of Chen Jian, and he loves natural science and mathematics very much, and this time he followed Chen Jian to the sea to see the outside world.

Although I have only just come into contact with Chinese since last year in Pattani, one grammar is the same, the second is that many pronunciations are only slightly different, and the third is similar to the writing, and you can find out the taste with a fine taste......

The fourth is the phonetic table written by Chen Jian based on the original phonetic cuts, which is extremely enjoyable to learn, although it is not proficient in less than a year, but it is no longer a problem to communicate with people, at most it is regarded as a foreigner.

They were with the group of people who were on their way to the capital, but stopped as they passed through Shanghai. Chen Jian only said that they should find a person named Xu Guangqi in Shanghai, because he had heard from Xu Xueju and Jiang Zhili that this person was familiar with astronomy and geography, and no one knew whether he had really heard it from those two people.

The person at the head is not only a supporter of Chen Jian, but also a member of the party, so naturally they will do whatever Chen Jian says, and as for the reason, they can always find a reason. For example, let the light of science spread all over the world, let truth become the cornerstone of the world, etc., or just to find the upper echelons in order to gain a foothold in the Ming Dynasty.

Different people need different reasons, and the reason given by Jian Chen sounds very similar to that, so these people didn't think much about it, and said that it would be great if they could establish a school here to spread science and truth, since they were looking for local upper-class people who knew astronomy and geography, then look for it.

After a little inquiry, they knew where Xu Guangqi lived, and several people went to visit with gifts.

Xu Guangqi heard that someone was visiting, and he didn't think much about receiving these people, and Xu Guangqi himself was surprised when he talked about it a little.

He was not surprised that some people knew their names, but they were surprised that these people introduced themselves, saying that they were from the far west of the country, and this time they sailed around the world to the Ming Dynasty to ask for trade, and they were entrusted with some gifts.

He had never heard of this country, for he was a well-informed man and had a close relationship with missionaries, but this was the first time he had heard of it.

Looking at the gifts, there were ten books, an oil lamp, a telescope, a box of matches, a flint short gun, an octave goniometer, and a thermometer.

If it was a gift like silver, Xu Guangqi was not pleased, but these things were exactly what he liked.

I know all the words, but when these words are connected, they are somewhat unclear, such as an octave-component goniometer and a thermometer.

From the name, it can be vaguely guessed, but it is still difficult to understand what it is.

The guest taught Xu Guang to use the telescope, and Xu Guangqi was also amazed to see that things in the distance were pulled in front of him.

After the guests lit a match, Xu Guangqi had already ordered someone to prepare a meal to entertain the guests, but he didn't want these people to say that these things were just playthings, just like a meal of pork that their parents said when children went to school, but children go to school not for pork but for knowledge, so please ask Mr. Xu Guangqi to read those books first.

He also said that in order to worry about hurting his eyes by the flickering candlelight of reading books at night, he also sent an oil lamp, and after helping to light it, he said that he was afraid that Mr. Xu Guangqi would take some days to read these books, so they left first and came back to visit in a few days.

At this time, the telescope had not been introduced, and this telescope alone had already made Xu Guangqi feel that these books could indeed be read, not to mention the rest of the fire and diesel lamps and other things.

Seeing that these people insisted on leaving, Xu Guangqi asked these people to stay here temporarily, and everyone agreed to come down.

That night, Xu Guangqi flipped through those books, and when he looked closely, he couldn't sleep at night because he didn't know the taste of food, and lit the lamps and lanterns called kerosene sent by the guests overnight, and he didn't realize that the sky was dawning.

There are not many books, but each one is something Xu Guangqi has never seen.

The book "Arithmetic and Geometry" is written in the vernacular of the market, but from the very beginning it introduces the logical system of mathematics in a straightforward and logical language. Xu Guangqi read a small part, and knew that this book is really a rare good book, and the content of the back is gradually obscure and difficult to understand, but it is inseparable from the previous lineage, and the more you read it carefully, the more you read it, the more flavorful it becomes.

Just reading this book made him forget to pray, something he hadn't done since he was baptized five years ago.

The more I looked, the more fascinated I became, and those guests only walked around the fields every day to observe the plants and plants here, or to inquire about some architectural matters, and they were not in a hurry or hurry.

He read arithmetic and geometry for three days, and some of the incomprehensible points in the past were actually integrated, especially after linking geometry and arithmetic together, which made the Pythagorean theorem, a truth that he had been puzzled for a long time, explain clearly.

However, when he looked back, he began to be a little difficult to understand, and he also knew that this book was not a day's work.

The most rare thing is that this book starts from the beginning, just like teaching enlightened children, starting from the simplest numbers, triangles, circles, and logic, and going deeper little by little.

Even people who have never been in contact with it before, as long as they calm down, can understand the content in a few months. Every new content must have a connection with the previous one, and every connection is also proved by some reasoning.

Although he had only read it for a few days, Xu Guangqi had already determined that the remaining books could be carefully studied, and they would definitely be of great benefit. Knowing that arithmetic geometry could not be understood in a day or two, he put down the book and looked through the rest of the books in the gift.

Looking at the bibliography, I couldn't help laughing, the names of these books are crude and ridiculous, but with the previous arithmetic geometry book as the foundation, I didn't dare to underestimate it, knowing that although the title was crude, there must be articles inside.

"How to Plant Sweet Potatoes", "How to Plant Cotton", "How to Save Sweet Potatoes in the North", "How to Plant Corn", "What Kind of Beans Can Increase Yield by Planting Wheat in a Year", "The Root Cause of Fertilization", "The Basis of Everything Talked About by Fertilizer", ......

Turning the page at random, there are various cultivation methods written in detail, and there are some hand-drawn illustrations, which are obviously not printed, but written separately, and the paintings are lifelike and extremely detailed.

After skimming a few sentences, I suddenly felt that this writing did have a deep meaning. As for those who talk about it, the harvesters may not be able to understand it, but the language of the market is more clear, and like those arithmetic books, the units of measurement and measurement in it are written very clearly, and there is never a rough number.

Only the content of growing sweet potatoes and corn in these books was written by Chen Jian himself, and the rest were only written by himself after being brought from China and asked someone to help translate them.

Including the arithmetic and geometry, it took Chen Jian five or six years to prepare, and the level is really not low.

It is true that stealing the theories of predecessors can be a blockbuster, but to write some simple things in the most understandable way is a silent work.

In terms of it, whether it is white phosphorus oil wells, particulate potassium and sodium, explosives and muskets...... Jian Chen is most satisfied with this book "Arithmetic and Geometry", which does not seem to have much new ideas, which is the most satisfying thing he wrote in his spare time.

Mathematics is a system, a system of perfect logic. Solving a problem can be famous for eternity, but that's what genius does. If you want to turn mathematics into a tool, this most basic and basic thing is the most important.

Embarking on the upper class route is just to gain a foothold, this dynasty has rotted to the roots, and it cannot be saved by one or two people who open their eyes to the world, and can only rely on the countless people of the ethnic group to be reborn from the ashes with their own struggle.

Chen Jian was sure that these things would arouse Xu Guangqi's interest, and Xu Guangqi's connections would give him enough opportunities to gain a foothold in some places where it was not easy to gain a foothold, and even open some new schools to recruit some talents.

Xu Guangqi had written the "Complete Book of Agricultural Administration", so Chen Jian was sure that this was not a scholar who thought that the matter of crops was a villain, but a person who could communicate with normal thinking, which was commendable.

Knowing that Xu Guangqi would be interested in books on mathematics, geometry, and agriculture was a breakthrough.

Mathematics goes without saying.

And those agronomy books, which seem ordinary, are actually a huge trap.

Especially the book about the relationship between fertilizer and crop growth, Xu Guangqi, who Chen Jian is sure to hook, itches unbearably in his heart.

To put it simply, it's just a matter of fertilization.

Looking deeper, it is why fertilization, what is the purpose of fertilization, what exactly is fertilization, what is the essence of fertilizer, and why is fertilization......

After this set of combination punches, it has to involve the worldview.

Logic, which began to be instilled in arithmetic and geometry, would influence Xu Guangqi's way of thinking in the long run, and gradually accept the methods of logical induction and deductive deduction.

At this time, Xu Guangqi didn't know that Jian Chen was like a fisherman, first using fish food to attract fish, and then quietly putting down a poisonous hook that couldn't be spit out.

You don't need to come up and talk about such mysterious things as the way of heaven and earth and the origin of the world, but you have to lure you step by step.

Once you take the bait, you can get up and down your hands and make a difference.

Starting from nitrogen, phosphorus and potassium, and then using electrolyzed water, frictional electricity, white phosphorus ghost fire, prism spectroscopy, chemical separation, mechanical gravity and other things, Xu Guangqi's three views were completely destroyed and his world view collapsed.

I dare not say dialectical materialism, mechanical materialism should not be a problem.

On writing articles and combining with Confucianism, Buddhism and Taoism, Chen Jian admits that he does not have this ability, but Xu Guangqi has. If the creation worldview of the Bible collapses completely, perhaps we can use the hands of this person to complete the localization of some ideas, or at least some translation work with more skillful and elegant writing.

It is naturally best to be reborn from the ashes, and if it is suppressed, then it is better to leave a glimmer of life, so that some scholars and doctors can come into contact with these learnings and not cut them off.

It seems that Xu Guangqi at this time has been hooked by the bait carefully prepared by Jian Chen.
