Chapter 27 The first popular science class in Datang
Naturally, Qin Hao did not suffer from stage fright. He calmly walked to the podium and wrote the word "Gewu" on the whiteboard with a charcoal pen.
"Students should know that Yun Ye and I are from the same school, and our school majors in studying objects."
"Before going to class, I think it is necessary to tell the students what gwu is."
While Qin Hao was talking non-stop on the podium, Li Shimin and his entourage had already arrived outside the classroom. Du Ruhui and Fang Xuanling originally planned to go in directly through the back door, but were stopped by Li Shimin.
"There's a lecture going on inside, let's not disturb it and just listen outside."
In fact, Li Shimin was afraid that his appearance would make Qin Hao have reservations. He wanted to gain a glimpse of Qin Hao's lectures and explore the secrets behind his sect.
Qin Hao also noticed that someone was eavesdropping outside the classroom, but he didn't care. Since the school was already running, there was no need to hide it.
"The so-called investigation of things, as Yun Ye said before, is to study the laws of the operation of all things in the world. But how to find the laws of the operation of all things in the world?"
Qin Hao said, writing two words on the whiteboard: appearance - essence.
At this time, except for Yun Ye, Li Gang, Yuan Tiangang and other teachers all frowned subconsciously. Only Yun Ye remained calm and calm, while the students were not sure why.
Qin Hao said unhurriedly: "The so-called appearance, as the name suggests, is the state of everything in the world. For example, some of the well-known phenomena are water flowing downwards."
"Students, have you ever thought about why water flows to lower places?"
There was silence in the classroom for a while, and then it started to get lively.
Li Gang, Yuan Tiangang and other teachers were also stunned. They really had not thought about this issue carefully. In their subconscious, water flows to lower places, which is eternal and unchangeable. It is as natural as people need to eat when they are hungry.
Li Shimin outside the classroom thought for a long time before looking at Du Ruhui and Fang Xuanling.
Du Ruhui and Fang Xuanling looked at each other and smiled bitterly. They didn't know how to answer this question.
Qin Hao smiled: "This is the knowledge of our school of research on objects."
"Let me ask the students a question first. In a pool with the same height up and down, will the water flow downward?"
Li Huairen immediately shouted: "Water flows to lower places. How can it flow if there is no lower place?"
"Yeah, how can water flow in a stagnant pool?"
The fat Li Tai looked at Qin Hao on the podium, frowning and thinking, is it really that simple?
When Li Huairen saw that everyone agreed with his point of view, he raised his chin proudly.
Qin Hao smiled and nodded at him, praising: "Classmate Li Huairen's words make sense."
"Then can we draw the conclusion that as long as the height difference is the same, the water will not flow downward?"
Most of the students below nodded in agreement. Only a few people like Li Tai were frowning and thinking, while others looked confused and didn't understand why Qin Hao would teach such a simple truth in class.
Qin Hao said unhurriedly: "Yes, the height difference is indeed one of the reasons why the water flows downward, but, as I just said, some of the things we take for granted in daily life, in fact, we only see the surface."
Li Huairen was a little unconvinced when he heard this. He stood up and saluted Qin Hao first, and then said: "Sir, isn't it?"
Qin Hao nodded to Li Huairen and motioned for him to sit down first, and then asked his entourage to bring over two transparent glass bottles. Yun Ye was happy when he saw them. They were not the wine bottles in his backpack before.
The students present didn't understand why Qin Hao asked him to take two half-filled bottles. Their attention was all attracted by the glass bottles.
"Wow, this glass is so crystal clear, it's probably a priceless treasure, right?"
"Isn't this the first time in eternity that you have used such precious rare treasures as teaching aids?"
Li Gang shook his head for a while, seeming to think that Qin Hao's move was inappropriate. Yuan Tiangang thought again. If these pairs of bottles could be obtained from the temple as a treasure, how many pilgrims would be attracted to them.
Outside the classroom, Li Shimin said to Empress Changsun beside him: "I originally thought that boy Yun Ye had a wild temper and Qin Aiqing had a calm personality, but I didn't expect that he would do such a reckless thing."
"Your Majesty, the man from Qin County used all the treasures of the master's family as teaching aids, which shows that he is dedicated to preaching. I am very lucky to send Tai'er to the academy to study." Empress Changsun said with a smile.
Du Ruhui and Fang Xuanling remained silent, but it was easy to see from their eyes that they did not agree with Qin Hao's behavior of easily showing off his master's treasure to others.
Qin Hao didn't care what those people outside the classroom thought. Under the curious eyes of the students, he took out another hose made of beef tendon from his sleeve.
Then, place one of the bottles on the ground and one of the bottles on the podium.
"Are these two bottles one high and one low?"
Li Huairen and the other students nodded subconsciously.
Then Qin Hao continued: "According to common sense, the water in these two bottles should only flow from the bottle on the podium to the bottle on the ground, right?"
Qin Hao said, picking up one of the bottles, pointing it at the mouth of the bottle on the ground, and poured the water into the bottle on the ground.
"Yes." Li Huairen and others nodded in agreement.
Qin Hao smiled, put the bottle back on the podium, then put one end of the hose into the bottle on the ground, took the other end in his hand, took a sharp breath, and finally put the end of the hose on the
On the bottle on the podium.
Then, a shocking scene occurred.
I saw the water in the bottle on the ground climbing along the hose, and then poured into the bottle on the podium.
"Water...is the water flowing back?" Li Huairen exclaimed.
Many students were shocked when they saw this scene.
Even Yuan Tiangang's face was full of disbelief, and he even whispered to himself: "Could it be that his two bottles are treasures that can make water flow back?"
Li Shimin, who had been hiding in the window and peeking, was also shocked by this scene.
This chapter is not over yet, please click on the next page to continue reading the exciting content! "How did he do it?"
Only Yun Ye hid in the back row of the classroom and snickered. After learning mathematics, physics and chemistry well, any magic would no longer be magical. At the same time, he secretly complained in his heart. He originally thought that he was the only one who liked to use modern science to shock the ancients and gain a sense of satisfaction.
Unexpectedly, Qin Hao, who usually seemed serious, was the same.
Li Gang keenly noticed Yun Ye's movements and immediately asked in a low voice: "Did your senior brother do anything in those two bottles?"
Facing Li Gang, Yun Ye was embarrassed to hide it and shook his head repeatedly: "Master Li, the bottle has not been tampered with in any way. This is a natural phenomenon. You will know it later."
"It's best this way. If you try to deceive the students by using some unflattering tricks, I, as the mountain leader, will not agree to it!" Li Gang snorted softly.
Just when Li Gang raised questions, some students also raised questions, and the chubby Li Tai stood up immediately.
"Mr. Qin, if you change two bottles, can you do it?"
Li Huairen and other students also began to suspect that the two bottles had been tampered with.
Qin Hao smiled calmly: "Of course."
Originally, he used these two glass bottles for this experiment just because the glass bottles were more transparent and allowed students to intuitively see the flow of water.
When Li Tai heard this, he immediately left the classroom and found that his father and mother were eavesdropping outside the classroom with a group of people.
Li Shimin glared at Li Tai, and then made a silence gesture. Queen Changsun waved at him, indicating that he would find a replacement.
Not long after, Li Tai came back from the cafeteria with two jars in his arms. It was difficult for him, a majestic prince, to have to do it himself. Sweat broke out on his forehead as he ran around.
"Sir, here you go."
Qin Hao did not pick up the jar that Li Tai handed over, but smiled at him: "If you don't bother me, I'll leave you to help me put the jar in place and add water to it."
"Okay." Li Tai agreed enthusiastically.
Then, in front of everyone's eyes, Li Tai had completed all the preliminary preparations. Qin Hao had not touched the two jars during the whole process, and even specially checked the hoses for Li Tai.
"That's right, it's a thin tube made of ordinary beef tendon."
After receiving Li Tai's confirmation, Qin Hao put one end of the hose into the jar on the ground again and took another deep breath.
Under everyone's surprised gazes, the water in the jar on the ground still climbed up tenaciously, eventually forming a stream of water and flowing into the jar on the podium.
"The water is flowing back!"
"This...it's fake that the water flows downwards!"
Li Huairen and other students all had a sense of déjà vu as their worldview collapsed. This was a phenomenon they had believed to be the truth since childhood, but at this moment it was overturned by two ordinary jars and a hose.
Li Gang also had a look of shock on his face, and subconsciously looked at Yun Ye: "Is this your master's secret skill?"
Yun Ye smiled: "It's not a unique skill, it's just the basics."
"Basics? Basics..." Li Gang muttered to himself, his voice getting softer and softer, until in the end only he could hear him.
Yuan Tiangang looked at Qin Hao on the podium with open eyes. If he could understand these "secret techniques" thoroughly and undergo some transformation, wouldn't he be able to become a Taoist miracle? The more he thought about it, the more Yuan Tiangang's heart became hotter.
Outside the classroom, Li Shimin's gaze was so intense that he murmured to himself: "Is this the secret method of their sect?"
Standing on the podium, Qin Hao motioned to Li Tai to return to his seat first. After the students gradually calmed down, he slowly spoke.
"You see, a small experiment can prove that water does not necessarily flow only to lower places."
Having said this, Qin Hao paused: "Students, this experiment is not just to tell you that water can flow from low to high, but to give you a concept. Don't be distracted by what you see in front of you.
Appearances may deceive you. Everything you see and hear must remain curious and explore why.”
"Perhaps there are many problems that we cannot explain today, but as long as we continue to explore from generation to generation, one day we will find the principle, and then use this principle to deduce the truth of many other phenomena."
Li Tai's face turned red with excitement and he clenched his fists with both hands. He had never been as excited as he is now since he was born. As the son of Li Shimin and the legitimate son of Empress Changsun, he was not the first in line to inherit the throne.
In addition, since he was a child, he has had almost everything he asked for, and there has never been anything that has interested him deeply.
At this moment, he discovered something that could keep him excited forever, and Qin Hao's voice kept echoing in his mind.
"Stay curious and explore the secrets of everything in the world."
This excitement was more pleasurable to him than any physical stimulation. He was so excited that he almost fainted on the spot.
Li Huairen and most other classmates also fell into deep thought after hearing Qin Hao's words. These dudes are not stupid. In fact, most dudes are very smart. The reason why they become dudes is not that they have no ability, but just because of their abilities.
Born, he is destined to be trapped in the family cage.
All their material requirements can be easily met, and even those who bully men and women will have someone to wipe their butts for them. But after a long time, such a life becomes very boring, and they can't find their life goals at all.
But now Qin Hao has given them a goal to chase, and it may be a goal that even their generation cannot accomplish. A sense of mission arises spontaneously, and it turns out that they can also do something meaningful.
Yun Ye was winking at Qin Hao when he suddenly felt a stabbing pain in his wrist. He looked down and found that the old man Li Gang was grabbing his wrist with an excited expression. Just as he was about to persuade the old man not to be so excited, he would be worried if he had a stroke.
When it's bad.
Li Gang suddenly stared at him: "Who is your master? What a huge ambition!"
Yun Ye was dumbfounded. What ambition? Which master are you talking about? Is it Newton, Galileo, or Einstein?
"Boy Yun, tell me honestly, how many people are there in your sect? What exactly do you want to do?" Li Gang growled.
Yun Ye just thought that this old man looked extremely weak, why was his hand so strong, and he explained repeatedly in pain.
"Master Li, you are overthinking. Our sect is now composed of me and my senior brother. I only want to spread the seeds of knowledge by running this academy."
When Li Gang heard Yun Ye's words, his eyes seemed clearer and he murmured to himself: The seeds of knowledge?
Outside the classroom, Li Shimin's eyes were flashing with a frightening light, and even Empress Changsun next to him did not dare to make any sound at this moment.
"Du Aiqing, Fang Aiqing, do you think the Qin County man and the Yun County man are pawns of some hidden school?"
Du Ruhui and Fang Xuanling looked at each other and shook their heads one after another. Although they had always been wary of Qin Hao and Yun Ye, it did not mean that they wanted to be enemies with them.
"Your Majesty, with all due respect, which school of thought has the luxury to treat such a talented person as a pawn?"
When Li Shimin heard this, the frightening light in his eyes subsided.
Yes, leaving aside Qin Hao, a talented person with both civil and military talents, even Yun Ye can be said to be amazingly talented. If this school is really extravagant to this extent, how come there is no trace of it?
