341 Three Laws (for December 1500

Emperor Chongzhen said, glanced at Li Dingguo and others, and then continued: "Water is in a liquid state. When it is boiled and reaches its boiling point of 100 degrees, it will become a gaseous state. The density of the gas is smaller. Relatively speaking,

It means that the required volume is larger, which means that the number of people in our room has changed from fifty or sixty, one to five hundred. If they can't fit in, they will naturally squeeze out. This is the same as the way gunpowder burns and produces thrust to fire lead bullets.

!”

To be honest, after hearing this, many people suddenly understood, but then they still seemed not to understand.

To them, it seemed that they understood something, but if they carefully understood Emperor Chongzhen's words, they found that there were many things they did not understand. For example, there was a very key word in the words just now, called boiling point. What is boiling point?

?

It seems that Emperor Chongzhen knew what they were thinking. Of course, the more important thing is that Emperor Chongzhen did not understand the term boiling point at the beginning and asked Liu Weichao.

Therefore, they saw him waving to Wang Chengen, then taking a glass tube from Wang Chengen, and then said to them: "This is called a mercury thermometer, which is used to measure temperature. I will never say that it is very cold today and it hurts."

How cold is it? Just take the fact that water can freeze as 0 degrees, and water boils to produce steam as 100 degrees. In this way, we can calculate the specific boiling point, or melting point, etc. of everything in the world, and this is very useful.

of!"

It seems that these words are not very easy to understand. Many supervisors listened intently, and it was obvious that they were frowning a little.

Emperor Chongzhen saw this and waved his hand again. Some of the other eunuchs who were in charge of rituals came forward to take away the kettle, while others brought a pot and put it on the stove.

After they finished their work, Emperor Chongzhen said to them again: "Now, let me give you an example..."

Experimental demonstrations are most welcome. Not only the supervisors, but also Li Dingguo and Liu Wenxiu became energetic.

They stared at the pot and the contents in the pot, all a little confused.

This time it’s not water, it’s oil. What is your Majesty doing?

Hmm, it seems to still have a slight vinegar smell.

When they were puzzled, Emperor Chongzhen said to them: "Just watch, I will show you how to get into the frying pan without getting hurt!"

"..." Upon hearing this, these Imperial College students were all dumbfounded, and then they all became excited.

The emperor wants to get into the frying pan?

Is this a show of magic?

In their surprised eyes, they saw the oil in the pot beginning to bubble.

This is boiling oil!

As soon as Emperor Chongzhen saw it, he said to the Imperial College supervisors below: "You guys should keep an eye on it!"

"Your Majesty, you must not do this!" When an older supervisor saw this, his face changed drastically and he immediately screamed.

If something happened to fry the emperor, wouldn't everyone present die?

On the other hand, those young supervisors were looking forward to it one by one and didn't think much about it at all. Or even if they thought about it, they didn't think that the emperor would seek death on his own, so it would be fine.

Li Dingguo and Liu Wenxiu had rebelled since they were young and had fought all their lives. They were relatively indifferent to life and death. They were not that afraid and believed that the emperor would do this only when he was sure.

Although the emperor was shocked that he wanted to do this, he did not stop him.

After Emperor Chongzhen heard the old supervisor's shouting, he just smiled lightly and said: "Watch it!"

As he spoke, he rolled up his sleeves and inserted his hands into the boiling oil pot.

His expression was calm throughout the whole process, as if what he was inserting his hands into was not a boiling pan of oil, but warm water.

Seeing this scene, especially seeing Emperor Chongzhen's unharmed appearance after retracting his hands, the eyes of all the Imperial College students almost bulged out.

Li Dingguo and Liu Wenxiu also looked incredulous. Even if they thought that Emperor Chongzhen would be fine, they were still very shocked when they saw it.

Feeling their gazes, Emperor Chongzhen felt very proud.

Even though he knew the principle of this experiment, he still didn't dare to do it the first time. He asked a chamberlain to hold out his hand first. After it was confirmed, he ordered it to be sealed and not to be told to anyone else.

Although Liu Weichao has mentioned that there are probably charlatans who can do this, but as long as the subjects of his experiments are not charlatans, he can have a good time.

No, these are all Imperial College students, and they are really shocked.

While he was showing his hands with a smile, the old supervisor who had tried to stop him suddenly left his seat, knelt down, and immediately shouted, "Long live my emperor, long live, long live!"

The gods have appeared!

No, it’s the True Dragon Emperor who has appeared!

The other supervisors were reminded, and they all knelt on the ground, overwhelmed by Emperor Chongzhen's dragon power!

Li Dingguo and Liu Wenxiu were also very shocked. They stared at Emperor Chongzhen's hand carefully, trying to find out what happened.

The two of them had visited the capital camp, used telescopes, and even Li Dingguo had seen microscopes, and they had already developed a certain resistance to weird things. Especially this time, the emperor was teaching the study of objects and

This is not to show magical means. Therefore, the two of them, who have experienced countless life and death, are much calmer than the supervisor. I just want to know the inner reason why the emperor is not afraid of the frying pan?

Emperor Chongzhen did not expect that the display effect of this oil pan would be so good!

For a moment, he didn't want to reveal the key. Wouldn't it be nice to let these ordinary people think that he was the real Dragon Emperor?

But in the end, reason defeated emotion. After all, there are still people in the world who know about this matter.

Therefore, he pointed his hand at the old supervisor and said: "Come on, come here!"

After hearing this, the old supervisor came forward in a polite manner and showed great respect to Emperor Chongzhen!

"What's your name?" Emperor Chongzhen asked with a smile.

"Student, you are right!" the old supervisor quickly echoed in a respectful voice.

Emperor Chongzhen remembered the name and ordered him: "Put your hand in and try it."

"..." Niu Youdao was startled when he heard this, and then hurriedly replied, "Your Majesty, the students are ordinary people. Without Your Majesty's magical hand protection, if this hand reaches in, it will be boiled to death!"

When Emperor Chongzhen heard this, he couldn't help but smile happily. When he was about to say something, he suddenly saw Niu Youdao gritting his teeth again, as if he had made great determination and said: "But your Majesty has decreed that students will not give up even if they die."

!Student...student reaches out now!"

Hearing this, Emperor Chongzhen nodded approvingly and had a better impression of Niu Youdao.

Seeing him nodding, Niu Youdao closed his eyes and then reached into the oil pan resolutely.

Other prison students were worried and did not even dare to look at it.

This Niu Youdao did not scream, but had a surprised expression. Then he opened his eyes, even pulled it down with his hand, and then said to Emperor Chongzhen in surprise: "Your Majesty, this... this is not hot!"

Emperor Chongzhen listened, nodded, smiled and said: "It is indeed not hot!"

Then, he ordered a few more supervisors to try it out, and even asked Li Dingguo and Liu Wenxiu to try it out.

Finally, Emperor Chongzhen said to the people who returned to their original positions: "The reason why it is not hot is because there are actually two things in it, one is oil and the other is vinegar. The boiling points of oil and vinegar are different. You see the oil

When the pot stirred, it was actually the vinegar that boiled first, because the boiling point of vinegar is 60 degrees, which is not enough to burn your hands."

After hearing this, everyone suddenly realized that it was because of this. No wonder they smelled a vinegar smell just now.

Just like the children of later generations, they really like to take science experiment classes. They are fun and novel at the same time. They satisfy the most basic curiosity and can be shown off when they go home.

After these supervisors understood the principle, they were all very excited.

Seeing their sudden realizations, Emperor Chongzhen felt happy and continued: "Boiling point and melting point are all physical properties. In a small way, they can be deceiving, but in a big way, you can use these properties to do things."

Things that benefit the country and the people, such as steelmaking."

"Okay, let's not talk about anything else. Let's talk about this steam train again. Why is its road special?" Emperor Chongzhen felt that the talk was very enjoyable and he did not mind that it was tiring, so he continued to talk eloquently, "This is it.

When it comes to friction, pressure per unit area, etc., I can explain it to you a little bit..."

While he was talking, the supervisors below, including Li Dingguo, Liu Wenxiu and others, were listening attentively, all of them were very serious.

He kept talking, and at the end, Emperor Chongzhen saw that it was getting late, so he stopped talking. Of course, it was not only because of the weather, but also because he didn’t have much in his stomach. Today he said

As he said it, he went beyond the scope.

Just listen to what Emperor Chongzhen said to them at the end: "In short, I have come up with three major laws from the study of objects. This is the most basic. You must listen carefully. One of them is about the movement of objects..."

When the Imperial College students and Li Dingguo heard Emperor Chongzhen speak so solemnly, they couldn't help but be very serious. They listened carefully with their ears raised, as if they were following the three laws of motion.

That's right, Emperor Chongzhen was talking about Newton's three laws of motion. It's just that he felt sorry for Newton's classmate. At this time, he was only a few months old and was still drinking milk!

The big boss in the world of macrophysics is no longer Newton but Chongzhen!

After saying this, Emperor Chongzhen felt that his mouth was dry, so he did not continue and drove back to the palace. Before leaving, he had the impression that he appointed Niu Youdao as the head of the fifty Imperial Academy students, as a way to contact the Royal Academy of Sciences of the Ming Dynasty.

Professor's assistant.

As Emperor Chongzhen left, the Imperial College students were released from school. Immediately, the content of the lectures spread around.

Suddenly, things like friction, boiling point, pressure, etc. suddenly became the most fashionable words in the capital. If you don't come up with a new word when you talk, then you have limited knowledge.
