Chapter 905
At the same time, the construction team was also busy. Most of the buildings in the Institute of Science and Technology were built by them in the later stage.
In the testing field, dozens of craftsmen stood there, staring at the things displayed in the field.
Four horses, two copper hemispheres with ring handles, a piece of oiled leather, and a piston tool.
Seeing that everything he requested was ready, Wei Wu nodded with satisfaction, then stepped forward to check.
No problem, the edge of the copper hemisphere is polished very smoothly and greased according to my requirements.
The valve holes on the hemisphere are also made very finely, and now we can start arranging the experiment.
"Sun Chang, have someone snap these two copper hemispheres together. Remember to place oil-soaked leather in the middle to create an airtight space."
After receiving Wei Wu's order, Sun Chang immediately arranged for people to do it, and soon the bronze hemispheres were spliced together.
"Very good. Next, have them use that copper piston pump to align with the valve hole and pump the air out of the sphere."
"This thing isn't very easy to pump. It only removes a small amount of air each time, so you have to repeat it about dozens of times."
"Remember, after you've pumped all the air out of the ball, you have to close the valve to prevent air from getting back in and making your whole process go to waste."
After Wei Wu finished speaking, the craftsmen below continued to do as he said, but this time Wei Wu looked at the craftsmen beside him.
"In fact, this step can also be replaced by water. Place the hemispheres in the water, snap them together, and then pump out the water."
"The main thing is to keep the inside of the sphere in a vacuum state so that we can proceed with the next step of the experiment."
After explaining to the craftsmen, Wei Wu stopped talking and the group of people watched the pumping process in silence.
It was not until more than an hour later, when the people below could no longer move, that Wei Wu nodded and said:
"Now the sphere is in a vacuum state. Without air inside, it will be compressed by the atmosphere and the sphere cannot be separated."
"This experiment can show you most directly that we are all under constant atmospheric pressure."
"Sun Chang, have them tie a rope to the handle of the copper hemisphere, and have two horses on each side pull the ball."
Then, under Sun Chang's command, the four horses were separated into two sides, and the ropes tied to their bodies were connected to the ring handles of the bronze ball.
Snapped!Snapped!
Two whip sounds were heard, and the frightened horses immediately started running, but they stopped after just two steps.
It’s not that they don’t want to run, but the rope tied to them is like tied to a wooden stake.
No matter how hard they tried, they could only straighten the rope, but could not separate the copper hemisphere in the middle.
Just as the craftsmen were concentrating on the experiment, Wei Wu spoke again:
"Okay, that's it for today's experiment. The purpose of the experiment is to prove to you that atmospheric pressure exists."
As soon as Wei Wu finished speaking, a craftsman beside him immediately asked.
"Mr. Vice President, we have indeed learned a lot about the existence of air pressure, but I have a question for you."
"Go ahead! What's the problem?"
Seeing Wei Wu responding to him, the craftsman quickly said:
"Which department of our Academy of Science and Technology is responsible for studying the science of air pressure?"
"Air pressure belongs to the field of climate meteorology. Which department does it belong to?"
After hearing Wei Wu's answer, the craftsman recalled what Wei Wu had just said.
"Yes, Gewuyuan?"
"That's right. Climate and meteorology belong to the field of physics. This atmospheric pressure experiment is called a meteorological physics experiment."
Hearing this, the craftsmen around all nodded and silently kept Wei Wu's words in mind.
As the craftsmen nodded, Wei Wu spoke again:
"Okay, if you still don't feel satisfied, you can continue the experiment and try to increase the number of horses."
"By continuously adding horses, we can see how many more horses are needed to pull the bronze ball away."
"That's all for today. You guys stay here and continue watching!"
After saying that, Wei Wu turned around and gave Xu Miao a look, then took him out of the test site and back to the preaching hall.
Who would have thought that as soon as he entered the door, before Wei Wu could say anything, Xu Miao couldn't help but ask a question.
"Teacher, may I ask, this physics you are talking about..."
"Don't even think about physics. Chemistry alone is enough for you to study for a lifetime."
Before Xu Miao could finish, Wei Wu shook his head and interrupted him, then continued:
"Physics is vast and profound. From the sun, moon, and stars to the rivers and seas, and even everything in this world is related to it."
"This is an endless science. Even if the wisdom of all people in the world were combined, we could only scratch the surface."
"As for me, I can only say that I have some knowledge of this subject, not even a tiny fraction, let alone teaching you."
Hearing this, Xu Miao quickly bowed and said to Wei Wu:
"It was the student Meng Lang who was being reckless. Please don't be upset, teacher."
It has to be said that Xu Miao's attitude in front of Wei Wu was absolutely correct, and Wei Wu was very satisfied with it.
"Next, regarding your teaching, I will spend an hour alone with you after the lectures at the Academy of Science and Technology every day."
"In addition to the basics of chemistry, you must also work hard on mathematics. I have only one requirement for you."
"That means you must rely on your own abilities and skills to become the number one in Miaohua Academy, not because of our master-disciple relationship."
As soon as Wei Wu finished speaking, Xu Miao immediately bowed to him.
"Teacher, don't worry, your students will not let you down!"
"Well, in the future, I hope to hand over the management of Miaohua Academy to you, so that you can teach and answer questions, and train more talents."
After hearing Wei Wu's words, Xu Miao's expression froze on the spot, and he spoke after a while:
"Teacher, do you mean that in the future, when your students succeed in their studies, they will also be able to teach others the knowledge you imparted?"
Hearing this, Wei Wu smiled slightly, spread his hands and said:
"Why not? My purpose in establishing the Academy of Science and Technology is to promote science, not to keep it to myself."
"But there is one thing I want you to remember: science has national boundaries. All knowledge and achievements must be based on the interests of the nation!"
