Civilization is like a middle school student whose studies are unstable, there is no need to be proud when standing on top of the world, and there is no need to be inferior when falling into a cliff. Judging from the history of the introduction of Christianity to China, China's leading position in the world has indeed been threatened.

As early as the ninth year of Tang Zhenguan, Adeben, who was a member of the Stolieu faction, met Taizong Li Shimin and Prime Minister Fang Xuanling in Chang'an, and stayed to establish a monastery and translate the classics. However, this exchange was only recorded as an exchange. During the Mongol and Yuan dynasties, with the expansion of the Mongol Empire, Christianity came to China again, but it was only as an envoy of different civilizations, and it was not able to communicate on the same status as China.

Now St. Francis, one of the founders of the Society of Jesus? Xavier had already died of malaria on Shangchuan Island off the coast of Guangdong, and was unable to set foot on the land of the Ming Dynasty in his lifetime. The successors of the Society of Jesus settled in Macao, which was leased by the Portuguese, thirteen years before they actually entered the mainland for cultural exchange.

When Xu Yuanzuo had a headache when he encountered a science problem, he hoped that someone would bring this textbook over. With his learning ability, even if he can't return to the peak state before the college entrance examination, the level of the high school entrance examination should still be sure - if he just pursues a passing grade. calmed down and recalled the process of the Renaissance, and Xu Yuanzuo's enthusiasm cooled down most of it. In his memory, the rise of mathematicians was still twenty years away, and scholars in the fields of physics, biology, and geography were still called naturalists, and there was no strict division.

Hmm, the father of modern mechanics and the father of modern science - Galileo? Galilei was only six years old, and it would be another two years before he could go to school, and most of his research was already in Xu Yuanzuo's "Physics Tips" - unsigned, unsigned. As for Galileo's student Tolicori, the child who discovered atmospheric pressure, the only historical task is probably to invent the barometer - Xu Yuanzuo has not yet started on this. But there is no guarantee that he will be able to build it before the Ming scientists.

However, in terms of physiology, European anatomists and painters have indeed gone ahead of the Ming Dynasty, and the small circulatory system of blood has also been discovered. After Xu Yuanzuo's death, he thought that he could ask a missionary from Macao to bring some human anatomy drawings and train local anatomists -- by the way, he would preemptively sign the copyright of blood group classification.

These are all intangible assets!

Xu Yuanzuo sat in class and wrote down all kinds of Western books he needed on paper. Mainly the writings of Euclid and Aristotle. As for today's Western writings, we can only say in general terms "modern writings based on ancient Greek civilization." The list will be sent to Macau with a team of three to be presented to the Jesuit presiding priest in Macau — if Xu Yuanzuo remembers correctly, Gianelo, who founded the San Rafi Hospital last year.

By the time he had finished this little list, he found that the class was very quiet.

Xu Yuanzuo raised his head and saw Li Teng waiting for him. For a while, it seemed like going back to the time when I was caught by the teacher reading a novel in high school chemistry class.

"How?" Xu Yuanzuo asked softly.

Li Teng said: "I just thought of a question. We already know that magnets are repelled by the same sex and attracted by opposites, if you use an anode magnet to pave the ground, and then wear anode magnet armor. Won't people be able to fly? ”

Xu Yuanzuo has a big head.

In order to implement his "giant rehabilitation" plan as soon as possible, the earliest natural science education was placed in the side hall of the Sanqing Temple. The students are four little Taoist children, and the teachers are Taoist Li Teng and half-hung Xu Yuanzuo. It is difficult to hold a full 45-minute class in this small class as in later generations, because both teachers and students will encounter various problems at any time.

Or come up with all sorts of questions.

It's a lot like a graduate program.

"Very good idea." Xu Yuanzuo first affirmed Li Teng's imagination, and then secretly said in his heart: If this black technology is called to you to come out, will the fraud of magnetic levitation be so high? Anyway. There were also people in the Ming Dynasty who tied gunpowder under chairs and tried to make earth rockets into the air, although in the end they were sure to fail. However, it is enough to prove that the imagination and spirit of exploration of our people are still very ...... Admirable.

"But it's important that the forces are balanced." Xu Yuanzuo said: "There is also the size of the repulsion. How to increase repulsion? ”

"How can I increase my repulsion?" Li Teng also asked.

――If I knew that I was still a liberal arts student?

Xu Yuanzuo coughed dryly and said, "Instead of thinking about this problem, I'm thinking about another question. ”

"Please." Li Teng walked over, and an apprentice brought him a chair and sat opposite Xu Yuanzuo.

"The force emitted by the magnet, regardless of yin and yang. Obviously, it exists objectively, not our subjective imagination. Xu Yuanzuo said.

Li Teng nodded.

"So the field generated by this force does affect the compass, does it mean that it also affects people?" Xu Yuanzuo asked again.

"I'm afraid it has something to do with Feng Shui." Li Teng said.

"Since we know that forces can affect each other, if we cut this force field. What will happen? Xu Yuanzuo said.

Li Teng fell into deep thought.

Xu Yuanzuo looked at the sun outside and gave an answer in advance: "I plan to try to cut the magnetic field with a copper coil." If successful, it should be able to generate current. If successful, it could be a new chapter in electricity. ”

Li Teng is no stranger to electricity. In the black technology inside the Daomen, the study of electricity is not unpopular - because of the symbiosis of thunder and lightning, in the oracle bone inscription, the middle of the word "thunder" is lightning. In practical application, the lightning rod was produced - a fish tail made of copper raised high; Or a raised dragon head that spits out its metal tongue and is dragged to the ground through hidden metal wires. The famous miracle of the Thunder and Fire Refining Hall in Wudang Mountain was actually built on the understanding of electricity.

It's not uncommon to artificially create static electricity, and it makes some sense to create an electric current.

"You get some copper wire, and I'll do this experiment for you." Li Teng naturally expressed his interest - maybe this thing can solve the mystery of Leifa. Maybe it can greatly lower the threshold for cultivating the Thunder Method!

Xu Yuanzuo was very satisfied with Li Teng's reaction and immediately agreed. Although the quality of the magnet is not very good, the copper wire tube is enough! Thanks to the cloisonné enamel craftsmanship brought by the Arabs three hundred years ago, you can now buy any specification of wire in Suzhou, Hangzhou, or Beijing. Although it can't be done in industrial production, the process is absolutely fine.

Li Teng leaned back in his chair and thought about how he would perfect the experiment. The most important thing is how to check if an electric current is generated.

He didn't know that there was a luminous object called a small light bulb, and he didn't know anything like an ammeter, but he couldn't stand his intelligence, and he quickly associated with the characteristics of electricity.

This thing is going to hit people!
