- Fang Yizhi was thrown to the Department of Public Works as Song Yingxing's assistant.
Song Yingxing was also inspired by Zhao Han in physics, but he was too busy with official duties, and he was not as active in researching physics as Fang Yizhi.
The two of them staying together should be able to spark some sparks.
Regarding physics, Zhao Han can only remember his junior high school knowledge, but he has long forgotten most of his high school physics, and he can't even remember a single high school physics formula.
He can only inspire and teach the methodology of studying natural science.
Fang Yizhi is in a state of madness, studying mechanics all day long. In less than half a month, this guy made his own dynamometer and asked craftsmen to make it.
? Song Yingxing expressed displeasure, saying that Fang Yizhi was not good as an assistant, and that he was distracted by various errands during working hours.
Zhao Han simply established specialized institutions, namely the Imperial Academy, the Academy of Mathematics, and the Academy of Physics.
This Hanlin Academy is not the Hanlin Academy.
The Imperial Academy of Ming Dynasty belongs to the central senior cadre preparation agency.
Zhao Han's Hanlin Academy is purely an academic institution.
?Research on Datong theory, compile Datong correct pronunciation, determine standard characters and dictionaries in the future, even recompile primary and secondary school textbooks, or compile "Ming History" after the fall of the Ming Dynasty, all these tasks are entrusted to the Imperial Academy for execution.
Officials of the Imperial Academy are not allowed to participate in politics, let alone be transferred to official positions with real power!
The Hanlin Academy, Mathematics Academy, and Physics Academy are temporarily under the direct jurisdiction of Zhao Han.
The Faculty of Physics is the poorest, with only Fang Yizhi alone.
Zhao Han ordered him to select 20 students, and while helping Fang Yizhi to do experiments, he also learned from Fang Yizhi. These students are not paid, but they are provided with food and housing.
There are so many houses in Nanjing Xu Guogong's house, and they will be distributed to various institutions in the future. For example, Wanzhu Garden is arranged to be the site of the School of Physics. The environment is absolutely elegant and the researchers are guaranteed to be happy physically and mentally.
"Headquarters!"
Another day, Fang Yizhi took out the schematic diagram, pointed to the drawing and said: "The object itself remains stationary because of the balanced force. Take this square inkstone as an example. It has the gravity of falling itself, and the desktop gives it upward force." Lifting force. When the lifting force is the same as the gravity, the inkstone can remain still. Just like people stepping on the mud, it will sink due to gravity. The deep footprints are the gravity of the person. When the mud is stepped on , the lifting force on the ground can counteract the force of gravity, and the person will not be able to stand still.¡±
Zhao Han asked with a smile: "So, what general (law) did you come up with?"
Fang Yizhi replied: "Everything thinks of tranquility. Any object, when it receives a balance force or no external force, it must be still."
Zhao Han crumpled Fang Yizhi's drawing into a ball and threw it out casually: "What kind of force did this paper ball bear?"
Fang Yizhi redraws the picture, thinks carefully, and constantly writes the force: "It is subjected to the force of the general town's throwing and its own gravity. When these two forces combine, the paper ball will fall forward."
"Really?"
Zhao Han took out another piece of paper, unfolded it without crumpling it into a ball, and threw it out, asking: "These two pieces of paper are equal in weight, and the force I throw is also similar. Why is one thrown farther and the other thrown away?" close?"
Fang Yizhi thought hard.
Zhao Han picked up a book, used it as a fan, and fanned Fang Yizhi: "Do you feel it?"
"Wind." Fang Yizhi replied.
Zhao Han asked: "Your hair moves with the wind, what kind of force does it bear?"
Fang Yizhi's eyes widened: "The wind is the movement of the air, and the air is the real thing!"
Fang Yizhi's understanding of wind in "Little Knowledge of Physics" is: Yin and Yang are driven by each other to move air, and ventilation can make wind.
Zhao Han smiled and approved.
Fang Yizhi added to the drawings again, and said: "The paper ball still has the resistance of air. When the resistance is balanced with the throwing force of the general town, the paper ball will no longernot right!"
From Newton's first principle to Newton's second principle, Fang Yizhi was stunned instantly. He felt that the problem was very complicated.
Zhao Han said with a smile: "I don't want to think about this for now. If my desk is extremely smooth and there is no resistance at all, will it stop after pushing the inkstone?"
Fang Yizhi thought seriously, shook his head and said, "No, the inkstone will keep moving forward."
"Then your previous conclusion is wrong. Things don't stay still, but keep their original state unchanged." Zhao Han said.
Fang Yizhi nodded: "Indeed."
Zhao Han said with a smile: "How about calling this representation of things 'inertia'? Consistency."
"Yes."
Fang Yizhi felt that this issue could be further studied, and he cupped his hands and said: "General Town, I will take my leave first, and go to the matter."p; Unable to suppress thieves anymore, Zuo Liangyu left Henan again, went to Shandong to rob food, and recruited refugees as soldiers along the way.
? Li Zicheng called on all bandit leaders to join forces to counterattack. Yang Guozhu and Wang Pu were defeated and fled, and were killed when they broke through like tigers.
Since then, Henan has become the territory of the rebels. Li Zicheng led his troops back to Shanxi, intending to take Shanxi and go straight to Beijing!
The current situation is changing so fast that it is dazzling to see.
?There is only one real reason: Zhao Han occupied Jiangnan, the salt lords fought in Jianghuai, and the imperial court was unable to collect taxes and pay military salaries
Far away in Europe.
The British bourgeois revolution officially kicked off this year.
In fact, it has nothing to do with the bourgeoisie, it is just a by-product of the Thirty Years War.
Britain has fought wars for decades, and the royal family has gone bankrupt. So they collected taxes crazily, forcing the nobles, merchants, and peasants to their death. The king also took the initiative to provoke religious conflicts, and the whole country was rebelled by a slapstick operation!
The Thirty Years War is still going on in Asia at this time.
The Netherlands realized that its army was not good enough, and spent money to hire thousands of Swedish mercenaries this year. Sailing all the way from Europe by boat to attack Portugal's eastern colonies, the main targets were Goa, Ceylon and Malacca.
As soon as the Portuguese fleet took away 500 Indian horses, the Dutch began to besiege Goa.
In the future, if Zhao Han wants to continue buying horses, he will probably have to pay heavy taxes to the Dutch, and Malacca will definitely be taken away by the Netherlands.
April.
500 Indian Warri horses arrived in Shanghai, all of which are strong and vigorous horse breeds!
It is a pity that more than 30 horses have died during the long-distance transportation by sea.
Zhao Han came to Nanjing again, the General Military Mansion was renamed the Dudu Mansion, and the entire team moved to Nanjing City.
Everyone knows what Zhao Han will do next.
Northern Expedition!
Northern Expedition!
