One Thousand Eight Hundred and Forty One Grand Meeting 2
Zhu Yunye didn't understand either. He turned slightly to Han Du and asked in a low voice, "What did Yang Qing do to win the first place in one fell swoop?"
Han Du smiled inwardly, but with a calm look on his face, he explained in a low voice, "He speculated through experiments that the earth under our feet is actually rotating."
"What did you say? The ground beneath our feet is turning?" Zhu Yunye frowned and glanced down at his feet.
It's not moving. Where is it moving?
He also secretly stepped on it hard, but there was no feeling of any rotation.
"Isn't uncle joking? How can the earth be so thick that it can rotate? If it is really rotating, wouldn't the huge force be beyond imagination?"
"It's indeed beyond imagination!" Han Du nodded.
Zhu Yunye's eyes were stunned. Is the earth really rotating? He looked down for a moment again, but he didn't see any sign of rotation under his feet.
"Uncle, why is this happening?"
Han Du rolled up his sleeves, came closer to him, and said patiently, "Yang Qing made a huge pendulum. According to common sense, if the ground under our feet does not move, the pendulum should swing back and forth in a line.
,right?"
"Isn't it like this?" Zhu Yunye suddenly became confused, "I have also seen a pendulum, which swings back and forth in a straight line."
Han Du chuckled and said, "Isn't the pendulum your emperor saw not big? It's only two or three feet in size at most?"
Zhu Yunye nodded subconsciously. When he saw the pendulum for the first time, he became interested in this novel thing and observed it carefully, but it was indeed like Han Du said, what he saw was nothing like it.
They are very big and can be placed directly on the table.
Could it be that this is also related to the size of the single board?
"The small pendulum actually does not swing back and forth in a straight line. It is just because the difference in swing is so small that it is difficult to distinguish with the naked eye, which makes us think that it swings in a straight line." Handu continued to explain.
"Yang Qing keenly observed this subtle difference, so he made a huge pendulum. Then he discovered the obvious difference. The pendulum did not swing back and forth in a straight line at all, but moved every time it swung.
It makes a subtle difference."
"Your Majesty, think about it. Since there is a difference, there must be a reason for such a difference. Later, after careful investigation, Yang Qing finally concluded that it was the rotation of the earth under his feet that caused such a difference."
Zhu Yunye listened carefully to Lailongqumai and finally understood it.
But at the same time, more confusion arose in his mind, "How big of a pendulum did Yang Qing make?"
"Probably, three stories high!" Han Du replied with a smile, "It's inside the Institute of Physics. If the emperor wants to see it, he can go see it at any time."
"Hiss!" Zhu Yunye just thought for a moment that there was a three-story pendulum, and he admired Yang Qing's talent.
He can detect subtle differences that others cannot detect, and this is what makes him special.
"Look, I must go and see it, but not now." Zhu Yunye winked at Fang Xiaoru who was standing on the high platform.
After a pause, Zhu Yunye touched his chin and asked, "So, does uncle think Yang Qing's statement is right or wrong? Is the earth under our feet really rotating, but why can't we feel it at all? If the earth is rotating
If so, then why haven’t we been
fall?"
Of course Han Du knew that Yang Qing's conclusion was correct. Who doesn't know that the earth rotates as long as they have studied junior high school physics?
However, he did not explicitly say that Yang Qing was right. Some things require students to study and verify on their own, and at the same time, it also allows people to slowly accept it.
"Anyway, Yang Qing ruled out the influence of the beams. He even thought it was the influence of the wind, so he moved the pendants into the house and sealed the windows tightly to prevent any wind from blowing in. The result was still that every day
Every swing makes a difference."
"The only thing that can affect the swing trajectory is the earth. Apart from the rotation of the earth itself, I really can't think of other impression factors."
After Zhu Yunye listened, he had to nod slightly. After excluding all factors that could affect the pendulum, no matter how incredible the final conclusion is, it is probably true.
"The knowledge in the academy is really profound. A simple pendulum can reveal such a huge secret." Zhu Yunye nodded first, then shook his head. It was not clear whether he wanted to express agreement or deny.
"But there is another problem."
"Your Majesty, please speak." Han Du agreed with a smile.
"If the earth is rotating, then why can't we feel it at all?" This is where Zhu Yunye feels most confused. If the earth is rotating and the pendulum can show differences, then people should also notice it. But since ancient times,
No one has ever felt this way.
Han Du smiled slightly and said, "I have a guess."
"Uncle, tell me quickly."
"I believe that when we stand on the earth, we are rotating with the earth. In this way, the earth is relatively stationary to us, so we cannot feel it."
This answer obviously did not satisfy Zhu Yunye. He quickly asked, "But the single pendulum is also placed on the ground, so why is there a difference?"
Han Du took the answer to explain to Zhu Yunye, "The pendulum is indeed set on the ground, but the rope of the pendulum is soft, and the rotation of the wooden frame does not affect the pendulum's ability, so we can see the difference.
"
"And Yang Qing also did an experiment on this. He made a pendulum connected with wooden poles. What did the emperor think?"
Zhu Yunye's eyes widened and he said in an excited voice, "Is this pendulum just swinging back and forth on the same line without any difference?"
"exactly!"
Zhu Yunye slapped his thigh excitedly, "Wonderful, it's so wonderful! Using a soft rope to eliminate the influence of the rotation of the earth and discovering the difference is so wonderfully designed. How did Yang Qing come up with the idea?"
"No! When this is over, I must go and see that pendulum with my own eyes. I will also call Yang Qing to me when the time comes. I will ask him how he came up with the idea."
"Yes, I will give my orders immediately."
The applause from the audience continued for a long time. Yang Qing stood up amidst the cheers, turned around and bowed to all the teachers and students, and then walked onto the stage step by step.
Seeing Yang Qing coming in front of him, Fang Xiaoru handed him the gold book.
Yang Qing quickly straightened his clothes, then leaned over and took it with his hands raised.
"Congratulations, you won the 100,000 yuan award from the Institute of Physics! This is a compliment to your knowledge and an encouragement to you. I hope you can continue to study in the future!"
"Thank you, sir!" Zhu Yunye didn't understand either. He turned slightly to Han Du and asked in a low voice, "What did Yang Qing do to win the first place in one fell swoop?"
