When the emperor came to the Academy of Sciences, what he saw and heard made him feel a sense of confusion, as if he had entered a mental hospital.

Two or three scholars were instructing craftsmen in the courtyard to make equipment, and it looked like a strange thing with a wheel and axle structure.

Zhu Youxiao hadn't recognized what he had made, and the scholars had already quarreled.

"According to the principle of leverage, this wooden tenon should be the most labor-saving here." A scholar pointed to the craftsman, "Come, change it, I'll make a mark with a pen." ”

The other Wensheng stopped and stretched out his hand to stop the craftsman, "I said it was a wheel axle, what lever are you pulling?" Irrelevant, what are you messing with? So saying, he waved his hand to the craftsman and said, "Don't listen to him, just make it according to the mark I have marked." ”

"The axle is actually the principle of leverage." Another scholar said: "I think Brother Zhou is reasonable, so what's the point of changing it?" ”

"If you can't change it, you have to rebuild it, it's the third time!" Wen Sheng pulled his face, looked at this, looked at that, and waved his hand violently, "Just according to a certain design, Brother Wu and Brother Zheng, please forgive me." Otherwise, when the craftsman is done, you can make a new one. ”

The craftsman's face is a little black, endless, reconstructed, remade, and tossed a fart. Isn't it just a home that wants to pump water, it's so complicated, and it's not so hard to carry water with a flat pole.

Zhu Youxiao smiled and turned to leave.

The theories in the book have been learned, but there is still a long way to go before they can be applied to practice. Keeping doing it and thinking about it is the most direct way.

I'll go! This guy is chubby, and he turned out to be a monkey?!

Zhu Youxiao suddenly saw a guy dressed as a scholar standing on the roof, and there was a guy below shouting and commanding, "No one, no one, drop it down!" ”

Fat Wensheng agreed loudly, stretched out his arms, let go, and the two balls fell. One was clearly an iron ball, smashing on the ground with a heavy sound; The other seemed to be a wooden ball, which bounced twice on the ground.

"At the same time, at the same time!" The Wen Sheng below shouted loudly, raised his hand and said, "If you can see it more clearly!" ”

Well? Is it necessary to build a leaning tower? Zhu Youxiao thought about it and felt that it was more economical to build a high Diao Dou. The fat man is so able to climb, he shouldn't care about the drops.

"Brother Shen, Brother Shen. Why is it too late, you want to mess with us. A greeting full of surprise and excitement came, Wang Ji Chongfei ran over, Lu Jianxing stepped forward to stop, but Zhu Youxiao stretched out his hand to block it.

Can't talk well? "Why are you here?" sounds very pleasing to the ear!

Zhu Youxiao smiled, opened his arms imperceptibly, just avoided Wang Jizhong's hand, and then slapped Wang Jizhong's two arms hard, "It's full of mundane things, so you have to wait for a long time." ”

Wang Jizhong laughed, and then said with a bitter face: "Brother Shen doesn't come to answer questions and solve doubts, everyone here will go crazy." ”

"No, no." Zhu Youxiao waved his hand and said with a smile: "If you think about it yourself and practice it yourself, you will have a deeper impression and a more thorough mastery." ”

After a pause, Zhu Youxiao continued: "Actually, when I talk about it, it's also those things in the book, nothing new. ”

Wang Jizhong shook his head again and again, obviously not believing the words of "Shen Lang". And after he shouted like this, many students gathered around and talked about their problems.

Although there were many people, the emperor still heard it clearly, and felt that it was much stronger than the childish question of the moon before. It seems that these people are also doing it themselves, thinking on their own, and have made some gratifying progress.

For the contact and vision of the ancient people, as well as the limitations of knowledge, it is indeed confusing and exciting to come into contact with these new knowledge and things at first glance.

is like Song Yingxing, who used to know what it was, but didn't know why. When all the skills can be explained by this principle and that theory, the impact on his psychology can be imagined.

It turns out that the growth of all things and the operation of things are all traceable and reasonable! At the same time as some sudden enlightenment, he also fell into a state of obsession, even madness.

Of course, this is for people who love to learn. Some people look through it, and I'm afraid they just throw it aside, don't explore, don't think.

Therefore, the emperor confined the scholars who looked more studious in this mansion. That's right, it's like a captivity, eating and drinking, reading and studying, but it's not going to let you go out.

If you are interested in learning, if you are not interested, you have nothing to do, read books to discuss research experiments, and in this atmosphere, you can also get a great driving and edifying effect.

Zhu Youxiao arched his hand in all directions, and when his voice stopped for a while, he said with a smile: "Everyone, please write down the questions on a piece of paper, and then take them to ask the master for advice." ”

Who else is taller than me?

Zhu Youxiao had a smile on his face, Lu Jianxing opened the way in front, and he and Wang Jizhong waited for acquaintances until they sat down in the hall to talk.

"Zhang Yitai is a little crazy, Brother Shen is here, just to explain." Wang Jizhong was a little helpless and a little anxious, "All day long, I either grind the lens, or look at that, that little thing." It's not right to look at other people's eyes, and he always holds a lens in his hand, as if he wants to check up and down. ”

It's something I haven't seen before, it's both fresh and obsessive! This, it seems that you have to explain it, don't make a fuss, do something out of the ordinary.

Zhu Youxiao nodded, and before he could speak, a scholar asked, "Brother Shen is talented, can you explain." According to the law of buoyancy, it is possible to build an iron ship, right? ”

"Yes." Zhu Youxiao said firmly: "I don't know if this brother has done experiments, the iron box and the iron block are in the water, if the weight is the same, the state is different." If the displacement of the iron box exceeds the weight, it can float on the water. ”

Wen Sheng blinked his eyes and said thoughtfully, "Iron-hulled ship? Is it possible? ”

Zhu Youxiao smiled, although there was not enough power, it was of little significance to build an iron-hulled ship. But this idea already exists, and if it continues to develop like this, there will be people who will continue to study it.

As for the steam engine, Zhu Youxiao felt that without more than ten or twenty years of all-out research and experiments, it seemed that he could not make a practical one. Therefore, there is no rush now, let alone the most important thing.

There is no peaceful and stable social environment, and there are no conditions for studying with peace of mind and improving the level of science and technology. At least in a year or two, Zhu Youxiao doesn't have much energy. With a few words of explanation and guidance, I hope that these people's understanding is good enough and their hands-on ability is strong enough.

Then another scholar asked a question, and Zhu Youxiao answered after a little thought. It is also a matter of linking theory with practice, and it is up to Wensheng himself to verify the specifics.

One by one, the emperor couldn't help but be troubled. Junior high school physics is only, not all, except that gravity is not very clear, Zhu Youxiao really asks and answers like a pedant.

The eyes of everyone looking at the emperor became more and more different. At first, I thought that Shen Gongzi had a good master, or he was lucky, and he got the knowledge that his predecessors had studied all his life.

But now, everyone knows that Shen Gongzi's understanding of physical chemistry is much higher than theirs. Looking at the age difference, how can you achieve this level without hard work?

Maybe—the books were all made up by Brother Shen, right?

Wang Jizhong looked at "Shen Lang" thoughtfully, and such a thought suddenly popped up in his heart.

It's no wonder that he is cranky, as far as those two books are concerned, if you don't understand them thoroughly, you can't answer them fluently, and every sentence is to the point.

In fact, these two books do not represent Zhu Youxiao's real level. No matter how advanced he is, he also knows that he only has limited time and energy, and he only makes up relatively superficial knowledge.

"Brother Shen, Brother Shen." Xu Fuyuan appeared at the door of the hall and waved enthusiastically.

Zhu Youxiao smiled and waved his hand, and saw that Xu Fuyuan was still followed by Zhang Yitai. Zhang Yitai stretched out his hand to hold a lens and observed Xu Fuyuan's neck, his eyes were shining, which startled Zhu Youxiao.

This guy is really not normal, as if he is going to go up and bite someone.

Xu Fuyuan glanced back at Zhang Yitai, and was also startled, and hurriedly reached out to pull out the lens of the opening ether, and pulled his sleeve towards Zhu Youxiao.

"Brother Zhang has made a great discovery, using a lens that he has polished himself." Xu Fu said loudly as he walked: "The water is full of small insects, all kinds of them, and they are all alive!" ”

Wang Jizhong just picked up the tea, and when he heard this, he hurriedly looked into the bowl, his eyes widened.

Similar to Wang Jizhong's expression, many people were now stunned, and those who had tea in their hands or on the table hurriedly lowered their heads to inspect it.

Zhu Youxiao smiled slightly, took the tea, and took a sip calmly before motioning for Xu Fuyuan and Zhang Yitai to sit down.

"Brother Shen-" Wang Ji looked at Zhu Youxiao seriously, and asked suspiciously, "Brother Xu is teasing us, right?" ”

"Don't you believe me?" Xu Fuyuan looked at Wang Jizhong, and then at "Shen Lang" who was not surprised, and reached out to pull Zhang Aether again, "Come, come, let them all see." ”

Zhu Youxiao smiled, waved his hand, and said, "There are many creatures in the water, which are invisible to the naked eye. But it's not appropriate to call them bugs, I call them microorganisms. ”

Zhang Yitai's eyes widened suddenly, looking at Zhu Youxiao, the stupid expression just now turned into surprise, and asked, "Brother Shen already knows?" Tell me, those worms...... No, are microbes harmful? What happens if you drink it in your stomach? ”

Zhu Youxiao took the teacup and said, "Brother Zhang hasn't observed this tea, or boiling water, right?" ”

Zhang Yitai shook his head and said, "What's the difference? ”

"There are microorganisms in raw water, and when the water is boiled, the microorganisms are killed by the heat." Zhu Youxiao explained: "Therefore, drinking raw water, especially unclean water, people will easily get sick. ”

"I see." Wang Jizhong saw that Zhu Youxiao was calmly drinking water just now, and listened to his explanation, and he didn't know why, so he was convinced, and took a sip of the teacup with confidence.

Zhang Yitai blinked his eyes, looked at Zhu Youxiao very suspiciously, and asked, "Why does Brother Shen know so clearly, does Brother Shen have a better lens and can observe more nuancedly?" ”

Zhu Youxiao pondered for a moment, stretched out his hand, and said, "Brother Zhang's lens, please borrow a certain view." ”

Zhang Yitai did not hesitate to hand over the lens in his hand to Zhu Youxiao, which was originally the most cherished, but Zhu Youxiao should have better, so this is nothing.

Zhu Youxiao took it in his hand and looked at it, and sure enough, it was the same as the development trajectory in history, Zhang Yitai thought of grinding the lens with a glass ball, and this idea was very remarkable.

However, a single lens is a single lens, and the magnification has reached the limit, and the observation of microorganisms will cause a distorted feeling.

Nodding slightly, Zhu Youxiao praised: "Brother Zhang spent a lot of time and thought hard to grind a lens with such a high magnification. ”

Zhang Yitai shook his head, disapproving of this compliment, and looked at Zhu Youxiao aggressively, knowing that there must be something else next. First praise and then turn, the speaking habits of the Chinese!

Zhu Youxiao smiled and said, "It's not a secret, there is also a lens like this, which is no better than Brother Zhang's." ”

"But-" Zhu Youxiao changed his words, looked at Zhang Yitai and said, "Brother Zhang can seriously study the knowledge about optics in the book, it will be very inspiring." I already have some ideas, that is, a combination of multiple lenses, and the magnification exceeds that of a single lens. ”

After a pause, the Emperor continued: "Well, so-and-so is going to call this new instrument a microscope. ”

"A mirror that shows microbes." Zhang Yitai nodded thoughtfully and said, "The single lens has reached this level, and I thought it was the limit. What Brother Shen said is very feasible. Optics, well, when seriously studied. But if Brother Shen made the microscope first, he wouldn't cherish himself with a broom, and he would definitely open his eyes. ”

Zhu Youxiao smiled and gently bowed his head and said, "There are many affairs, I'm afraid I just think about it." Brother Zhang studied hard and will definitely be able to study the microscope before he does. ”

Xu Fuyuan was a little puzzled, and asked: "Brother Shen, dare to ask, what is the practical significance of taking time and effort to build this microscope?" ”

Zhu Youxiao pondered for a moment and said, "Brother Xu, do you know why the wound is swollen, or pus, or even life-threatening?" ”

Xu Fuyuan frowned, thought about it, shook his head and said, "I don't know." ”

Zhu Youxiao said: "That's because the wound is infected, and there are microorganisms that cannot be seen with the naked eye multiplying in the wound. If we have a microscope, we can see which microorganisms are causing the damage and what kind of things can be used to kill them. ”

"Boiling water-" Wang Jizhong blurted out, and then he couldn't help laughing, "The injured person was also scalded to death!" ”

Several students also laughed, thinking that Wang Jizhong's words were too casual, and it was a little funny to think about it.

"There are microorganisms that are harmful to people, but there are also beneficial to people." Zhu Youxiao said with a smile: "At first, I felt that it was useless to look at what I couldn't see with my eyes in a mirror, but if I studied it deeply, I would find that this was not the case. ”

Zhu Youxiao stood up, looked around at the students, and said loudly: "Isn't the truth of the operation of everything exactly what we are exploring?" What we are accustomed to in our lives is often unaware of its principles. ”

As he spoke, he pointed to the table and said, "Why is it that the four-legged stool is the most stable, and the three-legged stool can be balanced, and the two-legged one, except for people, why is it unstable?" ”

"If you have read the book carefully, you must know that this is the matter of gravity. If you touch the loaded truck, you will not put heavy objects on it, so as to avoid unnecessary trouble. ”

"Some people may say that learning these things may not be useful, and when you don't, you can live well." Zhu Youxiao pursed the corners of his mouth, revealing a hint of contempt, and then said: "But you can think about it, from the Shang and Zhou dynasties, or the earlier era of the Three Emperors and Five Emperors, to the present, if there is no progress in science and technology, what would it be like?" ”

Everyone's faces showed confusion and contemplation, and they blinked their eyes slowly, and they couldn't imagine the scene assumed by "Shen Lang" for a while.
