PS: There are two more chapters tonight, around 11 o'clock and 1 o'clock

In Anpingjun's mansion, Tian Dan felt a little uncomfortable, not only Tian Jia, the daughter who suddenly appeared and watched Chang'anjun's performance attentively, but also Zou Yan's uncle and nephew who were talking to each other and had doubts, he couldn't help but sigh in his heart, a good feast, but now it has become a school palace classroom. Pen fun and pavilion www.biquge.info

Seeing that everyone was interested, Tian Dan didn't want to spoil the fun, so he could only listen patiently, who expected that when he heard this, even he was attracted by what Chang An Jun described.

With the sound of brushing, on the blackboard, Chang Anjun used chalk to draw a commonplace "material change process diagram" in middle school physics textbooks, this diagram that spans the era, appeared in the Warring States period in the third century BC, presented in front of Zou Yan, Zou Zheng's uncle and nephew, so that they couldn't take their eyes off.

"The gaseous state becomes a liquid state, which is liquefaction, and this process is exothermic. When a solid state becomes a liquid state, it melts, and this process absorbs heat. The liquid state becomes solid, which is solidification, and this process is exothermic. The transformation of a solid state into a gaseous state is sublimation, and this process absorbs heat. The gaseous state becomes solid, which is condensation, and this process is exothermic ......"

Mr. Zou Yan's curiosity has not diminishedBack then, whenever Mingyue proposed a change in the state of matter, he would raise his own questions, as if he was criticizing him.

Fortunately, those common sense of life are clear to modern people, Mingyue not only drew the relationship between the three states of matter, but also gave corresponding examples such as water condensation into ice, iron heating into molten iron, orpiment and realgar heating and gas, etc., to prove it, so that Zou Yan could not find fault with it.

And when he began to use this set of theories to deduce the process of rainfall and snowfall, he did not expect that he accidentally solved a problem that had plagued the ancients for thousands of years......

"The water on the ground evaporates into gas, rises high into the air, turns into tiny droplets or ice crystals, forms visible clouds, and the water vapor in the clouds condenses, and finally descends to the ground, which is what we are accustomed to rainfall, snowfall, and even hail."

As soon as these words came out, not only Tian Jia was slightly stunned, but even Tian Dan, who was not very interested in it, was also surprised.

The father and daughter said in unison:

"The clouds are water?"

"That's why it rains?"

Or Zou Zheng is well-informed, he thought for a while, and said: "Decades ago, there was a medical officer of Qi in the school palace, in the name of the Yellow Emperor, wrote a book "Su Wen", which also mentioned that the earth is cloudy, the weather is rain, the rain is out of the earth, and the cloud is out of the weather. I've been thinking hard about what this earth qi is, and today after being taught by Chang'an Jun, it suddenly dawned on me that it was ordinary water vapor......

"The gentleman is really knowledgeable and knowledgeable......"

Zou Zheng's reaction made Mingyue break out in a cold sweat, I thought that the process of breaking the rain was beyond the vision of the times, who would have thought that the native Warring States princes had relied on long-term observation and put forward an assumption that was extremely close to the truth, how could he not be embarrassed?

However, Zou Zheng was still immersed in excitement and said: "I have also read from the ancient books of the ancients, the qi of yin and yang, each according to its own place, is quiet; If it is biased, it will be windy, if it is thunder, if it is traffic, if it is electricity, if it is chaotic, it will be foggy, and if it is peaceful, it will rain; If the yang energy wins, it will disperse into rain and *** qi will win, and it will condense into frost and snow; The dedication of the yang is hail, the dedication of the yin is hail, and the hail is also ...... of the transformation of one qi."

"Originally, I thought that this statement was rootless and unfounded, but today I listened to Chang Anjun's explanation of the changes in the three states and apply this law to it, and I knew that the rain and snowfall were indeed caused by the change of yin and yang acting on the water vapor!"

The Yin-Yang family is not the original creator of the theory of the five elements of yin and yang, they only combine the two concepts of "yin and yang" and "five elements" since the Spring and Autumn Period, believing that gold, wood, water, fire, and earth are the material basis of the world, and yin and yang are the causes of their changes.

Although this concept was already very advanced in B.C., it was unfortunately too broad, and it sounded very reasonable at first glance, but if someone used common examples in life to question in detail, Zou Zheng could not explain all those phenomena one by one. Therefore, there are not many people who believe in this theory, and they still privately regard Zou's uncle and nephew as "a strange thing to look at the news of yin and yang".

Nowadays, with the "three states of matter" proposed by Chang Anjun as a supplement, many phenomena seen in daily life can be caused one by one, which is simply a huge complement to the five elements of yin and yang, how can Zou Zheng not like it?

However, when he looked at his uncle excitedly, who expected that Zou Yan's face did not have a sudden relief, but became a little gloomy.

Zou Zheng couldn't help but chuckle in his heart, the secret way is not good!

Zou Yan didn't express his opinion for a long time, Zou Zheng didn't dare to speak, the atmosphere suddenly became a little subtle, and finally Tian Jia came back to his senses and laughed: "If Chang'anjun's statement is true, the country witch who advocates the rain master Fengbo's rainfall will hate you." “

Mingyue couldn't help but wonder: "Why?" ”

Tian Jia puffed his hands and said: "Since miracles such as rain and snowfall in the eyes of ordinary people can be explained clearly with simple truths, no one will ask Wu Zhu to pray for rain on a dry day, and the ministers can no longer use the drought as the reason for the king's immorality......"

This sentence seemed to be a joke, and it seemed to remind Mingyue of something, and then looked at Zou Yan's face, he suddenly realized that if this set of rainfall is spread and widely accepted by the world, it will not only smash the rice bowl of ghosts, gods and witches, but I am afraid it will also dig up Zou Yan's roots!

Sure enough, Zou Yan was silent for a while and then slowly spoke:

Although Chang'anjun said this is reasonable, but the changes of heaven and earth yin and yang are so wonderful, we were born in it, but it is a drop in the ocean, and people's knowledge is limited, how can we explain the infinite changes of heaven and earth so simply? It's so irreverent! The old man thinks that the water vapor in the sky shrinks and shrinks, and the clouds and rain change, in addition to being natural, there must be a providence at work, and the sky listens to its own people, and the sky sees itself and the people, so the rain, dew and thunder are all the embodiment of the chaos in the world, how can it be covered up in simple words? ”

……

Half an hour later, it was already dark, and at the gate of Anping Jun's mansion, Zou Yan's uncle and nephew boarded the car and left, and this unhappy banquet came to an end.

Tian Hu, who came to send Mingyue on the order of Tian Dan, whispered to him: "Chang'anjun, my cousin just called me into the room and asked me to pass the word on my behalf, saying that you are afraid that you have offended Zou Zi today......"

"Why didn't she come and tell me that in person?" Mingyue couldn't cry or laugh, it's all at this time, that "Tian Jia" is still pretending, is it true that when she changes into a woman's clothes, he won't recognize it?

However, the girl's reminder was not out of nowhere, and he was only afraid that he would really have a grudge with Zou Yan tonight.

When Mingyue talked about material changes, she completely forgot one thing, that is, although Zou Yan was known as the "Yin and Yang Family", in fact, he learned from Confucianism in his early years and agreed with the "benevolence, righteousness and frugality" advocated by Confucianism.

However, Confucius and Meng, who were earlier than him, tried to sell "benevolent government" and "royal way" to the Warring States monarchs, but they all ended in failure, and they were ridiculed and boundless.

So the clever Zou Yan changed the way of sales, and he created a set of "five virtues always" theory based on the five behaviors of yin and yang, which is not very different from the Confucian set of moral and political theories in disguise.

According to Zou Yan, each regime will correspond to a certain virtue in the five elements, gold, wood, water, fire, and earth, and be supported by that virtue. When this virtue weakens, it will be replaced by another virtue that "grows together", and the regime will change accordingly. For example, the earth is born of wood, and wood makes fire, so the Yellow Emperor was a native at that time; Dayu was Mude at that time......

In order to win the trust of others, Zou Yan pieced together this set of things into "more than ten thousand words", which is very capable of bluffing people, and also listed the disasters and blessings that fell from the sky, such as great drought and heavy rain, intending to intimidate those arrogant and lascivious kings who are "not virtuous" and control their selfishness.

This set of theories was later absorbed by Dong Zhongshu and became "heaven and man induction", and later, the theory of yin and yang and the five elements no longer had any scientific basis at all, but was filled with the theory of Wei Wei.

But as Mingyue said, if rain and snowfall are just natural phenomena and have nothing to do with ghosts and gods, how can people believe in the five virtues?

"In the final analysis, Zou Yan is just a doctor who needs to use the theory of yin and yang and the five elements to find a basis for his political opinions, not a pure scholar."

This is like geocentrism and heliocentrism are both theories that explain astronomical phenomena, but because geocentrism caters to the theocratic theory of the church, it is very popular, and in the face of further heliocentrism, it is ushered in crazy denial and suppression, and its supporters are also denounced as heretical......

Similar to that incident, in the end, Zou Yan may become a conservative who resists this statement!

Mingyue shook her head helplessly, it seemed that his idea of getting praise from Zou Yan and sticking gold for himself had failed.

"Today's matter, I'm afraid it will soon be known to the Jixia School Palace, I don't know how many people will support it, and how many people will besiege it?"

……

On the other side, when he left Anping Jun's mansion, the old Zou Yan also slowly said to his nephew Zou Zheng: "Chang'anjun, you are really not the same traveler as us......
