Li Jinglong didn't go. Zhu Su's study had been designated as a forbidden area for the Zhu family since the last time Zhu Biaozhen took away all the manuscripts. Xiang Deng, who was also the temporary manager of the imperial village, hurried out and brought it after a while.
A small glassware.
"Isn't this thing just a broken piece... What does this mean?" Everyone was puzzled.
Zhu Su didn't answer. He took the small thing, which was only the size of a finger. It was part of the Qianyuan glaze he found in the palace collection. This glaze was not of the highest quality, and the color was extremely impure. But there was a piece of it.
, but it is a crystal color that is very close to transparent.
So Zhu Su broke the ornament, leaving the nearly transparent part, and ground it into a prism to tease his sister Princess Huaiqing in the palace.
This is just the right time to scare these scientific idiots.
"Fang Xizhi." Zhu Su walked to Fang Xiaoru. "Stretch out your hand."
Fang Xiaoru didn't understand what he meant, so he took two steps to Zhu Su's side, stretched out his hand and put it in the sun. Zhu Su took out a prism and fiddled with it slightly, and suddenly, a rainbow appeared in Fang Xiaoru's palm.
"Ah!" Fang Xiaoru was startled. He retracted his hand and wanted to get closer, but the rainbow actually fell to the ground. He was shocked and wanted to squat down to build the rainbow. Zhu Su gently fiddled with the prism, and the direction of the rainbow changed, and it shone on the ground.
on him.
"Now that the rainbow is on you, do you feel that you are filled with yin energy?" Zhu Su smiled.
Fang Xiaoru shook his head numbly, feeling inexplicably shocked. The rainbow was really picked off by His Highness? Is the sage's statement really wrong?
"You...have you really mastered this rainbow way?" Xu Yungong was also shocked. In his heart, Zhu Su was already a genius in arithmetic. Even his sister, who had always admired him, was also impressed by Zhu Su's arithmetic skills.
He was very admired for his achievements. He memorized Zhu Su's problem-solving ideas at Zhu Xi's wedding that day. His sister and he studied it sleeplessly for several days and nights. The more they studied, the more profound and profound it became.
In just a few lines of words, his attainments have surpassed those of the sages in arithmetic several times!
Being able to master this level of arithmetic is already an achievement that is difficult for ordinary people to achieve in their lifetime. As a result, he actually also has attainments in Gewu?
Picking off a rainbow from the sky with your bare hands is like a deity’s behavior in mythology!
Fang Xiaoru, Xu Yungong, and even Li Jinglong and Zhu Shouqian all looked shocked. Fortunately, the soldiers had already finished lunch and lined up back to the camp, and there were only a few of them left in the canteen. Otherwise, it would have caused a sensation.
"This...is this also knowledge?" Fang Xiaoru looked up at Zhu Su. Is this really knowledge and not magic?
"You look down on this knowledge?" Zhu Su thought that Fang Xiaoru was questioning the uselessness of this knowledge, and snorted arrogantly. "How can this not be knowledge? The name of this science is 'optics'. The so-called rainbow is actually just like this everywhere.
Visible sunlight is generally the same..."
"Rainbow is sunshine?" Li Jinglong looked in disbelief. "Uncle Wu, please don't lie to me. Sunlight is just one color, but rainbows have many colors. You can tell with your eyes that they are not the same thing..."
"This is a joke caused by not practicing optics." Zhu Su said with a smile. "You must know that sunlight actually contains seven colors."
"As long as you have basic knowledge of optics, you can easily extract these seven colors from sunlight."
As he spoke, he played with the prisms in his hands. Everyone moved their heads closer to look, and found that indeed, as long as the sunlight passed through the prism, it naturally turned into a rainbow!
"What's the point? What's the point?" Fang Xiaoru felt her heart itching unbearably, and looked at Zhu Su with the eyes of a young woman who had been hungry for decades.
Zhu Su deliberately ignored him, but looked at Li Jinglong and said with a smile: "Jiujiang, I will teach you this knowledge later."
"If you are proficient in optics, you can see thousands of miles away, slice ice to make fire, and have all kinds of wonderful uses. What's the point of catching a rainbow with just one hand? It's just the lowest level of means."
"You have a far-sighted vision, and you can cut ice to make fire?" Xu Yungong was shocked. That was really a magical method! Li Jinglong was even more delighted, "That's great! I didn't expect you, Fifth Uncle, to be able to use such magical methods! My nephew will definitely take good care of it." study!"
Even Zhu Shouqian pursed his lips, feeling extremely excited.
"Your Highness! Xiaoru has such a shameless face, can you help clarify Xiaoru's doubts?" Fang Xiaoru was already very thirsty for knowledge, but now that he had heard about such a piece of knowledge that he had never heard of before, how could he not feel itchy? He grabbed Zhu Su and asked him. I want to kowtow to him.
"Don't ask about poetry?" Zhu Su said with a smile. Fang Xiaoru blushed. Of course he knew that compared with practical abilities such as farsightedness and cutting ice to make fire, mere poetry was insignificant. Just talking about farsightedness, if it was placed on the battlefield In the formation, can we not only gain an advantage over the enemy, but also how many casualties can be reduced by the scouts?
Of course, you can't just teach him everything you have as soon as he asks. You also need to make him completely convinced, so that you can use Fang Xiaoru's literary works to flag up your own "Gurus". Zhu Su has not forgotten that Lao Zhu asked him to establish a sect. How could he let go of such a good chess piece brought to his door? So Zhu Su continued to pretend to be Boyi and said: "One piece of optics is just one of the ears."
"My study of things is extremely profound. All things in the world are encompassed and studied. Physics, chemistry, mathematics, medicine, etc., all exist for the purpose of exploring the great road of heaven and earth."
"The purpose is to understand the principles of everything in the world and to use it for all the people. If Confucianism was born to govern the country and bring peace to the world, then my goal of studying things is to understand everything in the world and use it for people!"
Fang Xiaoru was stunned again and again. The study of things? This young Fifth Highness, what he knew was not just a partial knowledge, but a complete school of thought?
Gewuxue...is this the name of this new school?
Fang Xiaoru felt as if his whole body was on fire.
Zhu Su, who had finished his holy performance in front of others, felt a little tired. He had just finished running a lap in the morning, and he was easily sleepy after eating. Although Li Wenzhong took care that he had other things to do and allowed them to take care of the time after lunch, but the time was still too long after all. Shaolian had to race against time to rest. He waved his hand and stopped Fang Xiaoru and Xu Yungong who wanted to ask more questions: "The way of studying things is profound and profound, and only smart people can understand it. I don't want to waste my words, so you two should answer me first. Just a few questions to get started.”
"Well... you can try making a cauldron out of paper, fill it with water and then burn it with fire. What will happen and why? If you think of it, tell me."
"If you burn paper with fire, what else will happen besides burning it?" Xu Yungong said naturally. "Could it be that after it is burned, the water will put out the fire?" Fang Xiaoru also added.
"No. In this way, the fire will not burn through the paper, and the water in the paper will be boiled by the fire."
"How is it possible! There is such a thing as paper that cannot be burned! It's absolutely impossible!" Xu Yungong felt that Zhu Su was bragging about Boyi!
"Young Master, you can go and try it yourself." Zhu Su yawned. "After you have answered this question, come and ask me other questions. I'm sleepy, Jiujiang, Tiezhu, let's go back to the village to wash up and rest."
"When you have thought about this most basic question, come find me again." He said and left the canteen.
