"Generally speaking, solids and liquids are considered incompressible." Zhu Qiyu answered Wanjieli's question, such as why a piece of iron was not crushed when placed in the air?

"Under certain special circumstances, it can be compressed." Zhu Qiyu added.

In the macroscopic state, solids and liquids are generally regarded as incompressible, but in the microscopic state, there are gaps between molecules and atoms, and everything in nature can be compressed.

Vangeli did not explore any special circumstances, but was thinking about what His Majesty said: Under normal circumstances, solids and liquids are considered incompressible.

He felt that he had glimpsed a shocking secret, but he had no idea what that secret was, and it was like a heavy fog that shrouded his eyes.

Zhu Qiyu didn't know what Wanjieli was thinking, and said with a smile: "Bold guesses, put forward hypotheses, carefully demonstrate, draw conclusions, come from practice, go to practice."

"Don't be afraid of doing something wrong. You should be more afraid of not doing it. Just do whatever you want."

"You are very good, I am very satisfied."

Humanity's understanding of the world is made up of specific events stacked one by one, rather than tall buildings rising in the sky. There is a knowledge warehouse of quantitative changes, and quantitative changes lead to qualitative changes.

It is only natural that studying a large number of problems will lead to a qualitative change in cognition and then rise to a general theory.

Zhu Qiyu has always hoped that everyone in the Ming Dynasty would be full of original curiosity about the world, have instinctive doubts about phenomena, and then use wild imagination. Finally, after a long period of discussion and demonstration, they would form conclusions and finally systematize and formalize knowledge.

This is science. Obviously, Ming Dynasty is making great strides forward on the road to complete science construction. Regardless of whether there are results or not, this is something worth celebrating.

Wanjieli saw Yuheng and Hengsheng drawing water three feet away. He kept guessing why, put forward his own hypothesis, and wanted to prove it. Finally, he got a few glass tubes in front of him, and verified the hypothesis through measurement, and got

came to a conclusion.

This means coming from practice and going to practice.

"I will obey the Holy Instructions." Xu Dun, Beilin, and Wanjieli said in unison. This was His Majesty's instruction to Qin Tianjian, so they naturally took it to heart.

"The Point Guard Is Here"

Zhu Qiyu studied the pillars in front of him again and asked a few questions. Of course, because mercury was poisonous, he, as the emperor, did not get too close to embarrass the courtiers.

We cannot talk about toxicity regardless of the dose, but the officials at Xing'an and Qintianjian are quite nervous.

Zhu Qiyu and several others discussed for a long time the application of atmospheric pressure. For example, based on the principle of a water pump, an air pump was made to preserve food for a long time, such as the improvement of the Hengsheng car and the solution for pumping water over ten feet.

etc.

"I remember how I asked the great craftsmen of the Ministry of Industry, Shijing Factory, Craftsman City, and the ten major calendar bureaus to do the job of miniaturizing steam engines?" Zhu Qiyu set off from Guangzhou at the end of February and spent nearly four months on it.

Just returned to the capital.

This is the second purpose of his visit today, to hear about the progress of steam engine miniaturization.

Xu Dun, Beilin, and Wanjieli looked at each other, then bowed their heads and said: "I feel guilty, there is progress, but not much."

Zhu Qiyu was slightly disappointed, but still said with a smile: "No rush, no rush, just take your time, take your time."

If it's really not urgent, I won't ask in person.

Xu Dun and others immediately felt the pressure. His Majesty was lenient and unwilling to put pressure on him, but Qin Tianjian and the Ten Liju Bureaus could not really think that His Majesty was not in a hurry.

From testing machines to large-scale industrialization, standardization, and standardized production, it is not an easy task. Zhu Qiyu is not too impatient. There are many problems to be solved.

"Your Majesty, I have something that I would like to ask your Majesty to examine." Seeing His Majesty's disappointed look, Beilin quickly bowed her head and said.

Zhu Qiyu smiled and asked: "Oh, what is it?"

Beilin bowed her head and said: "Your Majesty, making cheese will warm the human body; making black beans will make it as warm as the armpits."

"When raising silkworms, if you feel your body is cold, the silkworms will be cold, so add cooked fire. If you feel your body is hot, the silkworms will also be hot, so use an appropriate amount to remove the fire. When frying tea, the fire used is usually the same as human body temperature. If there is too much fire, the tea will be burnt and inedible.

"

"When water boils, it makes a slight sound like the eyes of a fish at the beginning, which is the first boil; the springs gushing out from the edges are the second boil; the waves splashing with foam are the third boil."

When preparing cheese, the temperature should be slightly higher than body temperature. When making tempeh, the temperature of the tempeh vat should be roughly the same as the human body temperature.

Silkworm farmers wear single clothes in the silkworm room and use body temperature as the temperature. If they feel cold, the silkworms will also feel cold, so they need to add firewood. If they feel hot, the silkworms will also feel hot, and they need to remove the fire to cool down.

When roasting roasted tea, the temperature should be about the same as human body temperature, otherwise the tea will be burnt and you won't be able to drink it.

Beilin continued: "The number of this boiling, the second boiling, and the third boiling is just a rough approximation. Since the degree bypass, I dare to use ice water as zero and three boiling water as hundreds to measure the temperature."

Zhu Qiyu felt that this passage was inexplicably familiar, and asked enthusiastically: "Oh? How to count human body temperature?"

Beilin bowed her head and said: "Everyone is different, roughly thirty-six to thirty-seven degrees."

"How to measure?" Zhu Qiyu asked again.

Beilin looked left and right, then scratched her head and said, "Your Majesty, please follow me."

Behind the statue of Mo Zhai, there is a five-story attic with no words on the plaque. It is obviously newly built.

This pavilion does not have the luxury of decorated beams and painted pillars, nor the beauty of pavilions, pavilions, ponds, pavilions, green pines and cypresses, or the beauty of rockeries and rocks.

An ordinary, elegant pavilion that doesn't even have a name.

On the left hand side as soon as you enter the door, there are spiral hydraulic presses, hydraulic forging machines, seismometers, flywheels, water and land livestock boats, etc. On the right hand side are lime blowtorches, water conservancy clocks, balance clocks, cylinder clocks, and six-minute watches.

Instruments such as armillary sphere and armillary sphere.

Beilin walked to a shelf, took down three wooden boxes, and opened them one by one. What appeared in front of Zhu Qiyu were three thermometers.

"One of them is filled with ink, one is wine, and one is mercury. Among them, the mercury column thermometer is the most accurate." Beilin introduced these three objects, which are three thermometers he carefully invented to measure temperature.

Beilin pointed at the thermometer and said: "The mercury column thermometer is an improved sample sent from the Taipei Hospital. It has no scale. It is generally only used to measure body temperature. It is more accurate, but it is inert. It needs to be shaken before use.

Throw it away."

There is a mercury column thermometer in the Imperial Hospital of the Ming Dynasty, which is about a bundle long and has only one mark. If it exceeds the mark, it means you have a fever and you need to cool it down. It is very simple, but the mercury column thermometer in front of you is much more accurate.

A wine column thermometer has no thermal inertia and changes as the temperature changes.

Zhu Qiyu took the three thermometers in his hand and looked at them carefully, and said with a smile: "Okay, very good, reward!"

"Thank you for your kindness, Your Majesty." Beilin quickly bowed her head and said.

Zhu Qiyu thought for a while and said: "Bring me pens, ink, paper and inkstones. This pavilion stores my Ming Dynasty's most amazing and obscene things. How can it be nameless?"

Zhu Qiyu thought about it for a long time and wrote three big characters on the paper: [Tiangong Pavilion].

From now on, this Tiangong Pavilion will be Zhu Qiyu's imperial box. Whenever he gets any auspiciousness, one will be placed in Tiangong Pavilion and another in Tai'an Palace.

When Zhu Qiyu walked out of Tiangong Pavilion, he stopped for a long time, thought for a while and then said to Lu Zhong: "Send a Tiqi Qianhu to guard, and don't get close to him for a while."

After Zhu Qiyu finished speaking, he left with a smile on his face. All inventions and creations from tomorrow will be included in it, and this five-story attic will definitely not fit in it.

But the Tiangong Pavilion has been erected, and it will have an immeasurable impact on the future of the Ming Dynasty.

The atmosphere has weight and pressure. In the eyes of Confucian scholars, this is too deviant.

If the atmosphere really has weight and can press water more than three feet high, wouldn't that person have been crushed to death long ago?

Qin Tianjian's remarks immediately aroused heated discussion in the capital and caused disputes after they were published in the Di newspaper.

This dispute was clearly divided into two factions.

One group firmly believes that the ten major calendar bureaus of Qin Tian Jian are deviant and deviant, and they should immediately ban the ten major calendar bureaus and allow Qin Tian Jian to resume its own functions. There is no pressure in the atmosphere.

The other faction firmly believes that it exists and has done many experiments to verify this statement. However, this faction is mainly composed of 500 astronomy students from Qintianjian. They are weak and no one wants to see them.

experiment.

Zhu Qiyu remained on the sidelines, making the discussion more intense.

"This envoy of the Muscovite Principality named Yin Fan, according to the system, should be received by the Minister of Honglu Temple. Why did the Ministry of Rites send this matter to my emperor?" Zhu Qiyu asked, holding a memorial.

According to the Ming Dynasty system, envoys from various vassal states could request an audience with the emperor through the Ministry of Rites. Most of the envoys from foreign barbarian kingdoms were received by the Minister of Rites. If they were from unknown small countries, they were completely handled by Honglu Temple.

The envoy of this principality, even the crown prince, has no right to request an audience.

Xing'an looked at the stamp on the memorial and said, "It was sent by the Ministry of Rites. Xiao Han and Yao Kui haven't returned to Beijing yet, so there should be nothing wrong with it."

Zhu Qiyu read the memorial carefully again and then said to Xing'an: "Go and find Yu Shaobao and Hu Shangshu."

The first time he saw this name, he felt a little strange, and then he remembered who this Yinfan Vasilyevich was.

The monarch of all Russia, the first tsar, and the founder of Tsarist Russia.

"I accept the decree." Although Xing'an didn't know why the prince of this small principality made his majesty so solemn, Xing'an still went to invite Yu Qian and Hu Hu to play a duel.

"I have come to see your majesty. Is your majesty bowing well?" Yu Qian and Hu Hui greeted each other.

Zhu Qiyu nodded and said, "Sit down."

Hu Hui seems to be living a happy life in his retirement days. His energy and energy seem to be much better, there is no fatigue, and Hu Hui's body and bones look quite healthy.

Zhu Qiyu handed the memorial to Xing'an and said: "I want to meet this Yin Fan, but how and what to say when I meet him. Yu Shaobao and Hu Shangshu will come and talk about it."

Yu Qian finished reading the memorial and said: "I have heard about this Yin Fanchen. Wang Fu and Wang Yue both said that this person was a great man. He never caused any trouble in the Ming Dynasty. He was quite forthright, made many friends, was diligent in learning and inquiring, and was regarded as a young talent.

But he is the heir to the Principality of Muscovy, so I am afraid he will not be able to stay as a Tartar official and serve His Majesty."

Hu Bi didn't read the memorial, but he knew what it was about.

"Your Majesty, why did Yin Fan travel east?" Hu Hui asked a question first, and then said: "He must understand the Ming Dynasty."

"Because the Ming Dynasty's expeditionary force is on an expedition to the west and has the potential to replace the Golden Horde, and the Kang State and the Ming Dynasty have an unclear and unclear relationship. How should we get along with the Kang State? It is the Principality of Muscovy, or rather

Slavs, something that must be thought about.”
