So, with everyone in the yard paying attention, Zhang Mingwei began to explain.
"The first question is, why can people only walk on the ground but not in the air?" Zhang Mingwei first asked the question and then answered it for them, "Because there is gravity! What is gravity..."
Newton was only fifteen years old, that is, he was born last year. Therefore, the universal gravitation was the first thing Zhang Mingwei proposed.
The reason why Zhang Mingwei keeps mentioning this is because universal gravitation and Newton's three laws are actually the basis of physics. To popularize physics in Ming Dynasty, this foundation cannot be bypassed. Therefore, he didn't mind talking about it in the capital and talking about it again in Jiangnan.
However, he talked about universal gravitation and said that all objects have mutual attraction. Just this statement made everyone dumbfounded except Zhu Yuluo.
When many people heard this, they looked at each other and didn't feel any attraction at all!
However, when many of them saw Li Xiangjun and others, they seemed to suddenly realize that they were indeed somewhat attractive.
Then when Duke Xingguo said this, did he forget to mention a premise? Should he add the relationship between men and women, or between men and women with talent and beauty?
But when they heard that this attraction was not related to a person's appearance, but was directly proportional to quality and inversely proportional to distance, they were completely confused. Where exactly was this attraction? Not enough!
While Zhang Mingwei was talking, he naturally saw their reactions and basically guessed what they were thinking.
So, he gave an example: "The reason why people can only walk on the ground is because the mass of the earth is too large, so it will attract us to the ground. Even if you jump up, you will only fall back to the ground." …”
Zhang Mingwei was not perfunctory and explained seriously.
The reason for this is that Jiangnan was the place where the literary style of the Ming Dynasty flourished. If the wind of science can blow in the south of the Yangtze River, it will have a multiplier effect on his promotion of science and technology.
There are many scholars here, and those invited by the top names are all of a certain reputation. If it can influence such a group of people, its help in promoting science and technology cannot be underestimated.
Therefore, Zhang Mingwei spoke seriously.
However, even if Zhang Mingwei said this kind of thing clearly and logically, this knowledge is really beyond the understanding of these people. Therefore, for a while, these people were more at a loss and still couldn't understand.
When he finished speaking about the first question, although most people, including Qian Qianyi, said "I see", they were actually not convinced in their hearts.
Zhang Mingwei didn't care, and went on to talk about the second question, which is based on gravity, and then talk about buoyancy; and the third question, which is how to overcome gravity, or overcome the constraints of gravity.
As soon as these questions are raised, just like the first question, these people, even if they are elite intellectuals of this era and are familiar with classics and history, cannot understand them.
After all, what Zhang Mingwei said is all based on truth, and it is not the kind of shock that seeing is believing. Most of it is pure theory.
When Zhang Mingwei finished speaking, he looked at Qian Qianyi and asked: "These three questions contain knowledge that, once learned and used, people will be able to fly in the sky. From Yangzhou to the capital, two or three people will be able to fly in the sky." The time has come. Even if you go to the moon to see it, you can go there. Do you think this kind of knowledge is serious knowledge that benefits the country and the people?"
"Yes, it is indeed!" Qian Qianyi looked ashamed after hearing this, and nodded quickly and said, "Such knowledge is really unheard of. I... the common people are ignorant!"
Wu Zhen and others, who were kneeling on the ground, also echoed, looking like they were being taught.
As for the other people, probably about half of them are also echoing. The rest bowed their heads and remained silent.
Zhang Mingwei noticed that Liu Rushi's face was obviously dissatisfied, but she looked at Qian Qianyi and said nothing in the end.
Obviously, many of them were just afraid of the power of Duke Xingguo, so they did not dare to disobey.
Zhang Mingwei knew it in his heart, but he didn't care, because they would just obey whatever was said at the moment. It will take a while for them to change their view.
So, he dropped the topic and asked Qian Qianyi: "I also heard that you have opinions on the music in Ming Pao, right?"
"..." When Qian Qianyi saw that Duke Xingguo had not given up, he couldn't help but secretly complain. He wanted to deny it, but how could he deny it when Duke Xingguo heard it with his own ears?
However, admitting it in person would once again arouse the dissatisfaction of Duke Xing Guo? To be honest, he didn't dare.
So, he felt a little embarrassed again.
Zhang Mingwei did not let him go, but continued to ask him: "Let me ask you, what is the music used for?"
His words made Qian Qianyi stunned again, and he asked himself in his heart: What is the music used for? Can't you sing?
Other people's thoughts are actually similar. Everyone is very strange, why did Xingguo Guild ask such a superficial question?
When Liu Rushi saw Qian Qianyi standing there stunned again, he quietly pulled down the hem of his clothes with his hand. The Duke is asking questions, how can we keep doing this, don't make the Duke unhappy again!
Qian Qianyi was pulled by him, came to his senses, and quickly replied: "Ordinary people think that music belongs to poetry and is composed to express certain feelings!"
Originally, he wanted to say that poems, lyrics, and songs all have their own requirements, and so does music. The previous song was obviously out of tune, and he didn't make a mistake.
However, seeing Duke Xingguo staring at him, he couldn't say these words.
After hearing this, Zhang Mingwei finally nodded, acknowledging what he said. This was the first time, and Qian Qianyi couldn't help but feel a little excited, secretly glad that he finally got the answer right for once.
Zhang Mingwei picked up the newspaper, showed it to Qian Qianyi with his fingers, and then asked: "You are very disdainful of this piece of music, right? It's because this piece of music can't be expressed unless it's written according to certain lyrics." Emotional?"
When Qian Qianyi heard this, his heart skipped a beat, and he dared to admit it.
But before he could say anything, Zhang Mingwei turned around and told Liu Jin and the others: "You all know how to sing this song. Come on, sing it to them!"
As soon as Liu Jin listened to Zhang Mingwei's instructions, of course he had nothing to say.
Therefore, these imperial guards in golden uniforms who had been following Zhang Mingwei all the time in the courtyard naturally had no problem, so they started singing together.
"He passed the Golden Ox Road with great vigor and high spirits. He protected peace and defended the land of Shu, which is to protect his hometown. A good man of the Ming Dynasty..."
More than 20 military officers in golden uniforms sang this song together. It was sonorous and powerful, and had a masculine flavor. It was definitely not comparable to the more formal tunes from Jiangnan.
Although they are not good at singing, the melody of this song does not have high requirements on the singers.
It can be said that this song was sung for the first time here in Jiangnan, and everyone in the courtyard was immediately shocked.
What is refreshing, this is refreshing!
Even Li Xiangjun and the others were originally going to sing this song, but suddenly they felt that they had misunderstood the true emotion of the song. If I had sung it before, I would have definitely not sung it well!
This is how this song is supposed to be sung!
After these Jinyi guardsmen finished singing, Zhang Mingwei saw that they had not come back to their senses and did not care about them, so he said: "This song was just after the New Year this year. At that time, the army arrived in Hanzhong, and the Shu area When the situation was tense, I had to risk going through the Golden Bull Road to rescue Shu, so I composed it. The army officers and soldiers sang this song, and finally passed the Golden Bull Road before the beginning of spring, and finally reached Shu and fought. The bandits and rebels were caught off guard, thus laying the foundation for the pacification of Shu today."
People in the courtyard were shocked by this novel piece of music. Now when they listened to the background of this piece of music, they thought of the imperial army, regardless of danger, passing through the Golden Ox Road before the beginning of spring, and thousands of troops marching, singing Play this song to hunt down thieves.
These people were shocked just by thinking about it.
To be honest, neither of them had ever dreamed of such a scene!
At this time, they seemed to really understand what it means to be bold and high-spirited!
"What a good man from the Ming Dynasty!" Liu Rushi thought about the scene in his mind and suddenly spoke with emotion, finally breaking the silence in the yard.
She is older than Li Xiangjun and others. Moreover, her early years were not very smooth. She experienced many storms, and she lamented that the imperial army was able to quell the rebellion and restore peace to the people.
Because of this, she was the first to express emotion.
After hearing what she said, the people in the yard came back to their senses.
Li Xiangjun and others, who were the most expert in music, were all amazed.
"This song is truly the most beautiful song I have ever heard in my life!"
"Yes, me too. I feel that after listening to it, even though I am a girl, I am still full of passion!"
"..."
They were like this, and so were everyone else, all marveling at this exciting piece of music that they had never heard before.
Of course, there are also some people among them who are afraid of the power of Duke Xingguo and are echoing the crowd's admiration.
However, whether it is sincere or not, as long as you observe carefully, you can hear it in addition to the actor-level acting skills.
Even Qian Qianyi had a look of shame on his face and said: "This piece is indeed an emotional piece that I have never heard before. It is so impassioned that it reminds me of my youth..."
When he said this, he suddenly came back to his senses. He seemed to have called himself an old man in front of Duke Xingguo just now!
Suddenly, Qian Qianyi's expression became panicked, and he quickly added: "The common people are convinced, they are indeed ignorant, and the music cannot be limited to lyrics!"
