Three Kingdoms: I Am Not an Ant Thief Chapter 708: Doubts in the Academic Circle
Xu Wei asked Zhuge Liang to assemble the copper ball and block the air holes on both sides, and then said: "Now we slowly fill the copper ball with water!"
Xu Wei slowly poured water into the air inlet. When it was full, Xu Wei tightened the air inlet and then began to open the air outlet. However, the water did not flow out much and did not come out again, even though the air outlet was pointing downwards. !
This scene surprised many students and was a bit contrary to common sense!
Xu Wei said: "This is the power of atmospheric pressure. Now this copper ball is almost sealed. The water that has just flowed out has created a little vacuum environment inside the copper ball. This has resulted in the maximum dry pressure inside the copper ball being less than what we have outside. , so the atmospheric pressure from the outside goes to the inside of the copper ball, preventing the water inside from flowing out! In this environment, water cannot flow to lower places!"
"Now we find a way to use a piston to pump out the water from the copper ball, so that we can get an almost vacuum environment."
After saying this, Xu Wei asked Zhuge Liang to continuously use the piston to pump the water out of the copper ball, but when he was halfway through, Zhuge Liang couldn't pump anymore! Xu Wei could only take over, and when he reached 90%, he couldn't pump anymore. moved, and then closed the valve.
"Now more than 90% of the water in this copper tube has been removed, and it is actually a vacuum environment inside, because almost all the air inside has been removed. The outside air wants to get in, but the outer shell of the copper ball blocks the air from entering. The path of the copper ball is equivalent to the force exerted by the air on the header, causing the two hemispheres to squeeze together tightly. You can try the magnitude of this force."
Zhuge Liang was most interested in atmospheric pressure. He was the first to pull the two handles outside the copper ball. As a result, he turned red, but the copper ball was still glued together perfectly. This aroused the interest of many students.
Xu Shu immediately said: "Kong Ming, I'm here to help you!"
After saying that, the two of them pulled a handle again and again. As a result, they pulled for a long time, but they still couldn't pull the copper ball away!
Finally, Xu Wei asked someone to find two hemp ropes several feet long, and then asked the students to continue to use their strength!
Zhuge Liang also asked 18 classmates to help, but the 20 people divided into two sides like a tug-of-war and still couldn't pull the copper ball!
Many students were shocked at this time. They did not expect that the light air could be so powerful that they could not usually see it. It was more powerful than 20 people!
Zhuge Liang wanted to continue asking his classmates to play, but Xu Wei stopped Zhuge Liang and said: "It will be too dangerous to continue. The teacher doesn't want to see you get hit by a copper ball!"
Then he said to the students around him: "Through today's experiment, everyone must have an understanding of the power of air. The teacher has assigned you an assignment. Think about it, this atmospheric pressure distance can be used in pressure-bearing wells. It hasn’t been used for anything yet!”
"Studying is not just about studying. You should also learn and apply knowledge while learning. Use the knowledge you have learned to benefit the people. This is what the teacher expects from you!"
"Okay, that's it for today's class, get out of class is over!"
After saying that, Xu Wei left the playground used for experiments.
And thousands of classmates around him also left in twos and threes!
Xu Shu and other scholars from Jingzhou gathered together. He looked at Xu Wei's back with admiration and said: "I can't imagine what kind of teacher taught such a genius as a ruler. Not to mention he was good at both civil and military skills, and even had knowledge of physics. They are all so knowledgeable, and a lot of knowledge has not been recorded anywhere else! And they teach us so generously!”
Pang Tong was also confused and said: "My family and my teacher are somewhat prestigious among the people who come to visit us, but the location of the ruling sect has not been found in the entire mountain gate of Daqian. Even the mountain gate in Jizhou is the same. The ruling sect seems to have appeared out of thin air!"
"Just like the knowledge taught to us today, it is completely unheard of and unseen in other families and schools. It is obviously the unique knowledge of the ruling party. However, these knowledge are extremely profound, even contrary to common sense, without the observation and observation of several generations and hundreds of years. Exploration can’t happen out of thin air!”
"So there should indeed be a huge sect behind the ruling party. The knowledge here even exceeds the knowledge of our Han sects and sects. How could such a huge mountain sect have no trace of knowledge? Even to this day, only the ruling person has appeared. , Logically speaking, the entire world now belongs to the ruling party. Even if the Mohist school’s knowledge was suppressed at the beginning, it should now come out and spread its own knowledge!”
Do you have any doubts about Xu Wei’s origins in the entire Han Dynasty and Shanmen?
Xu Wei is the best in the world in terms of military, politics, economy, and even machinery. This is naturally due to his personal talent, but the teacher's teaching is obviously also a very important reason, especially Xu Wei's knowledge system is obviously completely different from that of the big man. , this can be explained by more than just talent.
Xu Wei has such a huge and complex knowledge system, as if there is someone outside the Han Dynasty who is more powerful than the Han Dynasty. Advanced countries have taught Xu Wei this knowledge.
But this is obviously contrary to common sense. The academic circles of the Han Dynasty are not closed. Their understanding of the known world is better than that of previous scholars after the Song Dynasty. However, among their known world, there is no one who can compete with the Daqian civilization. civilization, even the recently discovered Tianzhu civilization.
By the way, change the source app to anyanapp version.】
Thanks to the blessing of the development of newspapers in Jidu, during this period of time, the information about the military, economic, political, religious, cultural and other aspects of Tianzhu civilization in the newspapers was displayed to the people of Daqian, so that everyone can have a deeper understanding of Tianzhu's country and civilization.
Although there are many merits, and there are many places that are more advanced than the Han Dynasty, overall, the civilization of Tianzhu is still not as good as that of Daqian. In particular, they are ruled by a group of magic sticks, which makes the academic circles of Daqian even more despised. As early as two thousand years ago, the rule of Shengun ended.
Recently, the Five Pecks of Rice Sect ruled the territory of a county, barely doing well, but compared to other princes of the Han Dynasty, Zhang Lu was useless and there was not much difference.
But what surprised the Dagan academic circles was that if Zhang Lu went to Tianzhu, he might even be able to become the master of the Ming Dynasty! Such a level of governance was naturally not taken seriously by the Dagan people.
Especially when they knew that Tianzhu was often invaded by northern nomads, and that the most powerful country in Tianzhu now, the Kushan Empire, was actually the Yuezhi previously recorded in history.
Then a formula immediately appeared in their minds: Daqian was stronger than the Han, the Han was stronger than the Xiongnu, and the Xiongnu was stronger than the Yuezhi. The Yuezhi was the most powerful country among the Tianzhu kingdoms, so Dagan was far stronger than Tianzhu. !
