333 [Upcoming Northern Expedition] (for the penguin boss
Fang Yizhi was thrown to the Public Works Department and served as Song Yingxing's assistant.
Song Yingxing was also inspired by Zhao Han about physics, but he was too busy with official duties, and his interest in studying physics was not as active as Fang Yizhi's.
If the two of them stay together, they should be able to create some sparks.
Regarding physics, Zhao Han could only remember the knowledge from junior high school, but he had forgotten most of the high school physics knowledge. He could not remember even a single high school physics formula.
He can only inspire and teach the methodology of studying natural science.
Fang Yizhi was in a crazy state, studying mechanics all day long. In less than half a month, he made his own dynamometer and asked craftsmen to make it.
Song Yingxing expressed his displeasure, saying that Fang Yizhi, an assistant, was not good enough and would be distracted during working hours.
Zhao Han simply established specialized institutions, namely the Hanlin Academy, the School of Mathematics, and the School of Physics.
This Hanlin Academy is not that Hanlin Academy.
The Hanlin Academy of the Ming Dynasty was a preparatory institution for senior central officials.
Zhao Han's Hanlin Academy is purely an academic institution.
Studying Datong theory, compiling the correct pronunciation of Datong, determining standard characters and dictionaries in the future, and even re-editing primary and secondary school textbooks, or compiling the "History of the Ming Dynasty" after the fall of the Ming Dynasty, all these tasks were handed over to the Hanlin Academy for execution.
Hanlin Academy officials are not allowed to participate in politics, let alone be transferred to official positions with real power!
Hanlin, Mathematics, and Physics are temporarily under the direct jurisdiction of Zhao Han.
The Institute of Physics is the most miserable, with only Fang Yizhi alone.
Zhao Han ordered him to select 20 students, who would help Fang Yizhi conduct experiments and study with Fang Yizhi at the same time. These students were not paid, but they were provided with food and housing.
There are so many houses in Xu Guogong's house in Nanjing that will be allocated to various institutions in the future. For example, Wanzhuyuan is arranged to be the site of the Institute of Physics. It has an absolutely elegant environment and ensures that researchers can be happy physically and mentally.
"Headquarters!"
Another day, Fang Yizhi took out the schematic diagram, pointed at the drawing and said: "The object itself remains stationary because the forces are balanced. Take this square inkstone as an example. It has its own force to fall, and the tabletop gives it upward force.
Lifting force. When the lifting force and gravity are the same, the inkstone can remain motionless. Just like when a person steps on a muddy swamp, it will sink downward due to gravity. The deep footprints are caused by the person's gravity. When the quagmire is stepped firmly
, the lifting force of the ground can offset the gravity, and the person can stand still."
Zhao Han smiled and asked: "So, what general rule did you come up with?"
Fang Yizhi replied: "All things are silent. Any object will definitely remain motionless when it is subject to a balancing force or when it is not subject to external forces."
Zhao Han crumpled Fang Yizhi's drawing into a ball and threw it out at random: "What force did this paper ball receive?"
Fang Yizhi re-drawed the picture, thought carefully, and kept writing down the forces: "It is subject to the force of the general throw and its own gravity. When these two forces are combined, the paper ball will fall forward."
"Really?"
Zhao Han took out another piece of paper, without crumpling it into a ball, unfolded it and threw it out, and asked: "These two pieces of paper are of equal weight, and the force I throw is about the same. Why does one throw far and the other
Close?"
Fang Yizhi thought hard.
Zhao Han picked up a book and used it as a fan to fan Fang Yizhi: "Do you feel it?"
"Wind." Fang Yizhi replied.
Zhao Han asked: "Your hair moves with the wind, and what force does it receive?"
Fang Yizhi's eyes widened: "Wind is the movement of Qi, and Qi is a real thing!"
Fang Yizhi's understanding of wind in "Little Knowledge of Physics" is: Yin and Yang are driven by each other to move the air, and ventilation can create wind.
Zhao Han smiled in approval.
Fang Yizhi added to the drawing and said: "The paper ball still has the resistance of air. When the resistance is balanced with the force of the general throw, the paper ball will no longer be... wrong!"
From Newton's first principle to Newton's second principle, Fang Yizhi was instantly confused. He felt that this problem was very complicated.
Zhao Han smiled and said: "I don't want to think about this for the moment. If my desk is extremely smooth and there is no resistance at all, will the inkstone still stop when I push it?"
Fang Yizhi thought seriously, shook his head and said, "No, the inkstone will keep moving forward."
"Then your previous conclusion is wrong. Things do not remain stationary, but maintain their original state." 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 explored, so he handed over his hand and said: "General Town, I'll take my leave first and go to clarify the cause and effect."
"Go." Zhao Han felt very pleased.
When Fang Yizhi walked to the door, Zhao Han suddenly shouted: "If you come up with any more results, you can invite people from the School of Mathematics and let them go to the School of Physics to have a look. Maybe we can get a few more like-minded people."
"Yes!" Fang Yizhi bowed and resigned.
Zhao Han leaned back in his chair and closed his eyes to rest. Physics research finally had a practitioner. He believed that if the fire was ignited, it would surely spread.
It's time to head to Nanjing. After the summer harvest, we will send troops to the Jianghuai River. The location of Ji'an is quite remote.
The General Military Mansion also had to be reformed, not only to establish itself as a king, but at least to be upgraded to the Governor's Mansion. Zhao Han decided to call himself the "Generalissimo of the World's Soldiers and Horses".
This position is comparable to Zhu Houzhao's "Governor-General of Military Affairs, Mighty General, Chief Military Officer"!
…
The thirteenth year of Chongzhen was destined to be extraordinary.
The Manchu and Qing armies had been surrounding Jinzhou for half a year and were arrogantly migrating to farmland outside the city.
Zu Dashou has always stood firm in Jinzhou City and showed no signs of surrendering.
How could he surrender?
The ancestral family has a great business in Liaodong, and can be said to be the emperor of Liaodong. Surrendering means losing one's basic base.
Unless we run out of ammunition and food, there is no way to survive.
Next to Jinzhou City, there are Songshan Fort where Wu Sangui was garrisoned and Liu Zhouzhi garrisoned on Xingshan Fort.
Wu Sangui was now panicking. He only had 3,000 soldiers in hand, and Zu Dashou was besieged under his nose for half a year. He kept asking the court for reinforcements, but not only did the reinforcements fail to arrive, but the army's salary was completely wiped out.
Throughout Liaodong, Chongzhen sent people one hundred thousand taels of silver.
It's useless to raise money, the court really has no money.
The military generals in Liaodong suddenly became loyal to the emperor and patriotic. Alas, if they don't pay the army, they won't be given. The war will still be fought, and surrender is impossible.
As long as there is still the slightest hope of becoming a local emperor, who the hell is willing to be a dog to the Manchus?
Liaodong has already allowed the establishment of regiment training, and Wu Sangui's father, Wu Xiang, was serving as the chief soldier of the Ningyuan regiment training at this time.
There is more than one general training officer of the Ningyuan regiment. Jin Guofeng also holds this position, and Wu Sangui is applying for this position. Anyway, these Liaodong generals, facing the arrogance of the Tatars, are spending their own money to recruit troops to fight.
Once they surrender, they are nothing.
They did not take the Ming Emperor seriously, and they also did not want to seek refuge with the Manchu Qing Dynasty. Their own interests always came first.
Just when Jinzhou was besieged for half a year, Subandai (a Mongolian) stationed at the Xingshan Beacon Tower secretly wrote a letter hoping that his entire family would join the Manchus.
The Manchu general Jierharang only led 1,500 men to respond. Wu Sangui, Liu Zhouzhi, and Dai Ming found out the news and joined forces with 7,000 men to attack and intercept. After wanting to win the battle, they returned to attack the Qing army besieging Jinzhou with Ningyuan soldiers.
.
7,000 Liaodong troops attacked 1,500 Qing troops, but were defeated and returned.
At the same time, the Mongolian Nomqi stationed in the outer city of Jinzhou secretly wrote a letter to surrender to the Manchus.
Zu Dashou learned the news and led his troops from the inner city to the outer city, killing the Manchu generals Mu Husa, Jue Luo Lantai and Hong Ke. Outnumbered, Zu Dashou retreated to the inner city and the Qing army occupied the outer city of Jinzhou.
The outer city has been occupied, but Zu Dashou still holds on to the inner city. It seems that he can hold on for at least another half year.
Huang Taiji was so flustered that he did not dare to consume food like this anymore, so he simply continued to send troops to attack Songshan and Xingshan.
Wu Sangui only had 4,000 soldiers left, half of whom were newly recruited regimental warriors, and they were tightly besieged in Songshan Fort.
…
On the Hubei side.
Xiangyang rebelled due to lack of pay. The soldiers killed the governor and the general, and all of them defected to Zhang Xianzhong.
Zhang Xianzhong then sent his troops to surround Yunyang. In Huguang's territory south of the Yangtze River, only Yunyang Prefecture was left that was not Zhang Xianzhong's territory.
Henan direction.
Yang Guozhu, Wang Pu, Zuo Liangyu, as fierce as tigers, are still encircling and suppressing Li Zicheng. They say they are encircling and suppressing bandits, but most of the time they are grabbing food. The imperial court cannot pay the army, and if they don't grab food, they will starve to death!
Not to mention officers and soldiers and bandits fighting for food, Henan is experiencing another severe drought this year!
The people of Henan really couldn't survive, so Yuan Shizhong, Li Jiyu, Liu Yuchi, Zhu Chengju and others rebelled. They didn't even bother to take a bandit name and directly used their real names to rebel. Zhu Chengju was even a member of the Ming Dynasty clan.
The whole of Henan is full of rebels from all directions.
These rebels all followed Li Zicheng as the leader, but in fact they followed the orders but not the propaganda. They captured the strongholds of the big landlords, formed strongholds one by one to protect themselves, and occasionally attacked each other.
Unable to suppress the bandits any more, Zuo Liangyu left Henan again and headed to Shandong to rob food and recruit refugees as soldiers.
Li Zicheng called on the bandit leaders from all walks of life to join forces to counterattack. Yang Guozhu and Wang Pu were defeated and fled. They were killed when they broke through the encirclement as fiercely as a tiger.
From then on, Henan became the territory of the rebels. Li Zicheng led his troops back to Shanxi, planning to capture Shanxi and then go straight to Beijing!
The current situation changes so fast that it is dizzying to see.
There is only one real reason: Zhao Han occupied the south of the Yangtze River, the salt owl was fighting in the Jianghuai River, and the court was unable to collect taxes and pay the army.
…
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 been at war for decades, and the royal family has gone bankrupt. So it collects taxes like crazy, driving the nobles, businessmen, and farmers to death. The king also takes the initiative to provoke religious conflicts, and the whole country rebels against him with this outrageous operation!
The Thirty Years' War was still going on in Asia at this time.
Realizing that their army was not good enough, the Netherlands spent money this year to hire thousands of Swedish mercenaries. They sailed all the way from Europe by ship to attack Portugal's eastern colonies, with the main targets being Goa, Ceylon and Malacca.
As soon as the Portuguese fleet transported 500 Indian Marwari horses, the Dutch began to besiege Goa.
If Zhao Han wants to continue buying horses in the future, he will probably have to pay heavy taxes to the Dutch, and Malacca will definitely be taken away by the Netherlands.
April.
500 Indian Marwari horses arrived in Shanghai, all of them are majestic and powerful horses of the best breed!
Unfortunately, more than 30 horses have died during 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.
