Chapter six hundred and seventy first ups and downs
This time, the public school said it had sent out two hundred invitations, but not all of the two hundred people were candidates. There were also a few students from Gyeonggi Province who had sneaked in. Of course, there were far more than 200 people in the lecture hall today.
Two hundred people, as well as other astronomy talents who came in with another batch of invitations, were invited to Beijing. Among them were Ye Mengqiu and others who lived in Zhangyuan.
In addition, there are undoubtedly some people who come first, such as Fang Qing, Song Juren, Zou Ming and other three Juren. Yang Zhan and Guan Qiu also rely on their status as residents of Zhangyuan.
, each got a seat.
At this moment, although His Royal Highness the Crown Prince was welcomed, many newcomers were surprised by the spring-like warmth in this lecture hall. Some whispered that the public school was rich, but there were also people who whispered against the luxury.
The little peanut who came to help today almost wanted to curse. It's such a cold day. If the walls of fire around the lecture hall didn't burn up, you would freeze to death!
But at this moment, Little Peanut also heard what Lu Sanlang said to the third prince. Except for those in Jiuzhangtang who had long been accustomed to the attitude of never treating the prince as a god or Buddha, everyone else in the huge lecture hall was
Their expressions changed. But what made them even more unexpected was that the third prince actually answered without thinking: "I wish I could be the teacher's assistant!"
The third prince was indeed happy to be Zhang Shou's assistant. As early as when he was at Banshan Hall, he had personally seen many very simple but very interesting experiments done by Zhang Shou, whether it was small hole imaging, triboelectricity... all kinds of things.
All of them opened his eyes, and he felt that there were countless secrets in this world.
At this moment, he stood at the edge of the podium without thinking. When he saw Qi Liang bringing a basin of water and placing it on the high podium, he couldn't help but look at it curiously. Just when he was a little confused, there were people below who couldn't bear it.
He couldn't help but exclaimed: "Crystal basin!"
Hearing the word "crystal basin", the third prince was slightly startled. Then he stroked the basin thoughtfully, which looked irregular in shape, and then knocked it twice. Then he raised his head and said with a calm smile:
"You have never seen this object before, so you mistakenly thought it was crystal. In fact, this is the glass that was fired by the teacher not long ago."
"The teacher has already dedicated the glass formula to the imperial court. Now the workshops under the Bureau of Ordnance are also trying to make it, but they are still unable to make such a large utensil. Unexpectedly, the teacher's workshop has broken through the utensil-sized utensils.
The limitation is that it’s not very transparent yet.”
Having said this, an excited voice came from behind him: "Brother Qi, why did the teacher take out this glass basin?"
Without turning his head, the third prince knew that the person behind him must be the fourth prince. Sure enough, after the person stepped out from behind him, he seemed not to see the reproachful look in his eyes and said to himself: "Senior Brother Qi, the third prince is the prince."
It’s boring for me to be an assistant by myself, so I’m here to help! Don’t worry, I will never do anything without the teacher’s instructions!”
Hua Qi, who was mixed in the crowd below, couldn't help but cover her forehead. If this naughty kid really didn't cause any trouble for a day, he would be unwilling to do so. If he had known better, he should have kept him in the palace!
Although most of the other people who came today did not know the Fourth Prince, they knew he was the Fourth Prince when they saw his age and heard that he was the third brother of the prince. Now they heard that this little guy was so shameless that he had to do something.
Assistant, thinking about the attitude of the third prince when he readily agreed to Lu Sanlang just now, I don’t know how many people became even more envious, jealous and hateful towards Zhang Shou.
At this moment, they finally heard a calm voice: "I'm really sorry. I was preparing some things inside, but I just didn't have time to go out to meet His Highness the Crown Prince, the Fourth Prince, and all my colleagues."
Zhang Shou did not wear an official robe today. Instead, he wore a Confucian scarf and a blue robe. But even if he wore these common clothes for scholars, he still looked like a tree in the wind and looked talented. So much so that he went out of his way to look good.
After dressing up, Zhu Ying, who disguised herself as a man and walked in among the crowd, looked up and down, but couldn't help but secretly pursed her lips and smiled. She didn't even notice that Zhu Hong's face turned pale.
Today, he originally followed Zhu Ying's order to invite the so-called wife, but who would have thought that the eldest lady entered a clothing store, claiming to be visiting a friend, and then she never came out. When he rushed in, he only saw that the lady was gone.
She had undergone a miraculous transformation, and when she saw him come in, not only was she unhurried, but she also took out two invitations and invited him to come with her without saying a word.
Of course he originally wanted to refuse, but Zhu Ying said that he had already obtained permission from the wife and madam in the mansion. The previous excuse was just to fool her father and brother. After all, those two people did not allow her to come over today, so he had no choice but to bite the bullet.
Followed. But when he thought of having to listen to a lot of things that he could never understand with a group of scholars, his eyes felt dim.
After all, others don't know how difficult the content of Zhang Shou's class is, but he does know it, because he has been ordered by Mrs. Tai and Duke Zhao to go to the bookstore many times to collect all the published volumes of "New Edition of Gurdjieff's Arithmetic".
Even because of Zhu Ying's relationship, he secretly sneaked into the Imperial College to monitor Zhang Shou's lessons to the students of Jiuzhang Hall. He would rather kill people on the battlefield than go through that kind of baptism again!
And at this time, sitting next to Zhu Ying, he had to be wary of whether the scholar on the other side might be a prostitute and take advantage of the eldest lady after discovering her disguise, and he also had to be wary of whether there was an assassin with ulterior motives in the crowd.
Waiting, so he secretly regretted that he should not have escorted Zhu Ying over alone before. But just when he was in a state of confusion, he suddenly felt a light poke on his back.
His whole body tensed up almost instantly, but he soon realized that it was not a stabbing, but someone poking his back with a finger, as if they wanted to say something to him.
After hesitating for a moment, Zhu Hong finally turned his head slightly, and soon found that directly behind him was Zhu Er, who was sitting with an innocent face. On the left and right sides of the person, there were Zhang Chen, Zhang Wu, Zhang Lu and a few other people.
He was a disciple of Guijie. The one who poked him at this time was none other than Zhang Chen!
The eldest son of the Duke of Qin winked at him, telling him to turn around quickly and not to disturb Zhu Ying. But before Zhu Hong had time to do so, Zhu Ying seemed to have noticed something and suddenly turned her head.
Seeing such a group of people sitting behind her, the eldest lady was just slightly startled, then smiled on her face, and then turned back without saying anything, but glanced at the other side of her. When she saw that Ming Ming
The scholar who should be sitting next to her was sitting upright, with his back straight, but his buttocks were only touching the edge. There was a big distance between him and her, so she laughed softly.
And when she smiled, she noticed that the person beside her seemed to freeze, and she suddenly understood. There was no doubt that people knew her. Even if she was disguised, strangers might not realize that she was a woman.
But people who have seen her can tell it from many details. Otherwise, how could those guys behind her sit so well behind her just now?
Well, of course, it could also be that Zhang Shou made arrangements in advance when he distributed the invitations...
But the person next to her now should not have been arranged by Zhang Shou, or in other words, she felt that the person next to her had a palace aura. Those were some of the people she saw in the Qianqing Palace and other places when she entered the palace since she was a child. In addition to the aura inherent in people, Uncle Hua, whom she is most familiar with, also has such an aura vaguely on his body.
Zhu Ying did not explore for too long because Zhang Shou on the stage had already started speaking.
"Jiuzhangtang once held open classes when I was in the Imperial College. At that time, I didn't take into account the outsiders' observation. I just talked about it, just like the blackboards I used to solve problems on the day of Lu Gaoyuan's crowning ceremony not long ago. Likewise, most people don’t understand it, so naturally the original meaning of the word “open class” is lost.”
"So, I originally planned to simplify the complicated today and talk about everything in a simple and profound way. His Highness happened to be here to watch, so I will use the hands of His Highness to demonstrate a few small experiments in public."
Although there were the third and fourth princes as assistants, Lu Sanlang still stood beside Qi Liang, preparing that if there was anything wrong with the brothers, he would immediately rush to make up for it. However, when he saw the people standing around to maintain order. Those classmates all had genuine confused expressions at this time, and he couldn't help but sigh in his heart.
When he first became a teacher, he was still a bit naive, but over time, he has become very convinced of Zhang Shou. But this teacher is good at everything, but there is one thing that he often likes to do without telling everyone at certain times. Wonderful drama!
Just like today, even he didn't know what Zhang Shou planned to say...
Of course, when he saw the glass basin, he actually had some bad premonitions in his heart. Not long ago, Zhang Shoucai made a ground-breaking conclusion among them-iron ships can float on the water!
After the unhurried opening remarks, Zhang Shou casually explained his experiment at the Sutra Banquet that Confucius University Scholar once dismissed as a demonic method. However, at the moment, he did not intend to show it in kind, but continued on. Said: "As we all know, people will sink when they fall into the water, iron and stones will sink when they enter the water, but light objects such as wood will float when they enter the water."
"Today, my first experiment is to show you a very simple sinking and floating experiment."
Having said this, Zhang Shou casually showed an egg in his hand. When the egg was put into the glass basin, the people who were eagerly observing could see through the basin body that was not too transparent that the egg sank straight to the bottom. . But before they could figure out what Zhang Shou wanted to express, they heard someone speak again.
"I think everyone has seen it clearly. Then, Your Highness, please add the things on the table to the water."
The third prince was thinking about what Zhang Shou's words had to do with the last class. When he heard the instructions, he immediately came back to his senses and hurriedly stepped forward to help. But when his hand shook, a small bag of white coarse grains next to him was suddenly covered. He poured it all into the basin! But before he could scream inwardly, Zhang Shou took a chopstick and stirred it vigorously in the water.
After a while, he saw a jaw-dropping scene. The egg in the water trembled and floated!
Although the people below had not yet had time to see clearly what was going on, they could still clearly see the third prince's expression that almost made his eyes pop out. As for sitting down on the podium at the invitation of Zhang Shou.
A lecture was given to everyone, and from the changes in the faces of the curious audience below, some predictions were already made.
Therefore, Chief Yue Shan stood up first and asked: "Is it because the eggs are floating in the water?"
As soon as these words came out, there was a small commotion below. Although some people had accused Zhang Shou behind his back before, but at this time, His Royal Highness, no one was as good as the Confucian scholar in Wenhua.
There were definitely more than one or two people in the palace who lost their composure and cursed the monsters in their hearts. But at this time, they only heard the fourth prince shouting loudly.
"Yes, it is true that the eggs floated in the water! But, teacher, what is the reason for this? What is the white stuff you asked the third brother to add? How come the eggs floated after stirring twice?"
Seeing that the fourth prince directly intercepted his question, Yue Shanzhang originally remained silent, but when he saw that Zhang Shou did not answer immediately, but turned around and looked at him with a smile, as if he did not care that he was suspected of causing trouble with this question.
, he hesitated for a moment, then simply asked: "If I guessed correctly, what was just added to the water should be salt, right?"
After hearing what Yue Shanchang said, there was an uproar, especially those who had been whispering to their companions just now, were even more stunned. Zhang Shou smiled calmly and said: "Chief Yue Shan is really wise and knowledgeable, that's right.
, it is the most common salt in ordinary people’s homes.”
"Why do I have such sharp eyes and profound knowledge? It's because I grew up by the sea when I was a child." Yue Shan smiled at himself, and then said calmly, "It has always been the case that shipwrecks will inevitably occur when sailing on the sea, although most of the time it is fatal.
There is no life, but sometimes, one or two lucky people will encounter a fishing boat and be rescued, and some claim to have been floating on the sea for a day or two."
"The sea is no bigger than a river, and even a good swimmer cannot cross dozens or hundreds of miles. But some of these lucky people don't even have a sampan, and are rescued purely by luck. Although most people regard this as a blessing from the gods, but I
After hearing about it, I also visited several people who had narrowly escaped death and were rescued, and finally I heard one thing they said."
"That is, in sea water, if it is not the coldest time of winter after falling into the water, the temperature in the water is suitable, and there are no storms, plus you are good at swimming, then it will be easier for a person to float in sea water than in a river."
Hearing Chief Yue Shan talk so eloquently, Lu Sanlang, who had heard Zhang Shou lecture on the buoyancy formula before, immediately widened his eyes. There were indeed similarities between what he taught today and the previous lecture, but he did not expect that someone who actively cooperated with Zhang Shou's lecture
It turned out to be President Yue Shan of Zhaoming Academy!
Not only Fatty Lu, but also Song Juren, who was very familiar with Yue Shan's personality, couldn't help but ask Fang Qing, "Is the sun coming out in the west? Your teacher seems to be humble, but in fact he is the most observant."
Someone who is above the top, will he speak for Academician Zhang? Is there any conspiracy here?" There is no doubt that he received a sharp blow from Song Juren.
Zhang Shoujian was talking even louder at this time. He did not open his mouth to remind or lecture, but nodded and said slowly: "As Chief Yue Shan said, His Highness the Crown Prince just added salt to the water, so originally,
The egg that sank into the clear water finally floated successfully, which is similar to the conditional floating of the human being in the sea water. So, why is this? "
