The next day, "Datang Daily" published an article written by Li Zexuan, called "Overview of Astronomy", which was an article to popularize basic astronomical knowledge to the public. In the article, Li Zexuan officially proposed to the public the solar system. concept, he pointed out that the sun is a star, and the earth under our feet is called the earth, which is a planet in the solar system, and there are five planets in the solar system: gold, wood, water, fire, and earth, and the planets in the solar system will surround the sun. change!

At the same time, he also pointed out that the time required for the earth to revolve around the sun is about three hundred and sixty-five days, which is often referred to as a year, so people can feel the changes of the four seasons in a year; the moon is a The satellite of the earth, it will revolve around the earth, and the time required to make a circle is about 27 days, which is about a month, so the moon will be cloudy and sunny every month; in addition, the earth will also Rotation, the rotation period is almost one day, so people can see the sunrise and sunset, day and night every day!

In addition, in this article, Li Zexuan also explained to the public the cause of the eclipse of the sun, that is, the moon moves between the sun and the earth. If the three are in a straight line, the moon will block the light from the sun to the earth. , the dark shadow behind the moon just falls on the earth, and a solar eclipse will occur at this time.

In order to better allow readers to understand the theory he said in the article, he also added some sketches of the trajectories of the stars. Basically, anyone who can read and write can understand the causes of solar eclipses! ,

Finally, Li Zexuan stated that the above-mentioned content can be observed and proved with the telescope of Yanhuang Academy.

As for why he only proposed the six planets in the solar system (gold, wood, water, fire, earth, and earth) instead of eight planets, it was mainly because the other two planets (Uranus, Neptune) were dim and orbiting. Slow, and at the edge of the solar system, the telescope of Yanhuang Academy cannot observe it, so now he can only tell people that there are six planets in the solar system!

In fact, the ancients mentioned several major planets in the solar system in astrology. The so-called "five stars" are five planets visible to the naked eye: "Mercury", "Venus", "Mars", "Jupiter", "Saturn"; .

Therefore, the concept of the six planets in the solar system proposed by Li Zexuan is still well understood! Coupled with the supporting evidence from the telescope of Yanhuang Academy, this theory is even more persuasive!

And Li Zexuan's intention in writing this article himself is to give the public a vaccination in advance for the vision of the Tengu eating the sun that will appear in two days.

Since ancient times, once the vision of the Tengu eating the sun appeared, it was regarded as a sign that the monarch was fainting and the country was about to die, which made the people panic, and those who had the heart would take the opportunity to rebel, and even encourage the people to rebel. Li Zexuan just wanted to tell the people in advance, Tengu eating the sun is just a normal astronomical phenomenon, and it has nothing to do with whether the emperor is faint or not.

Once this article was published in "Datang Daily", it immediately caused a huge sensation. The world outside the earth, such as the sky, the moon, and the sun, has always been very mysterious in the hearts of the people, and the stars like the moon and the sun have always been very mysterious. , In many ancient myths and stories, there are special meanings, and now Li Zexuan has unveiled the mystery of these stars and formally proposed the concept of the solar system.

"What? The earth under our feet is spherical? And it revolves around the sun?"

"Look at this picture, there are five other planets that revolve around the sun just like the earth?"

"Bullshit! Complete nonsense! How could the earth under our feet be spherical? Also, how could the earth under our feet revolve around the sun? Doesn't the sun revolve around us? That's why we see day and night!"

"It can't be said that the Marquis of Yong'an is nonsense! Because according to Marquis Yong'an's point of view, we have four seasons of spring, summer, autumn and winter to explain it! The distance from the sun is winter, and the distance from the sun is summer! A year is a cycle, and it also happens to be a revolution cycle!"

"And Yong'an Hou's view that the earth can still rotate is also unique, because if the earth's rotation period is one day, it can explain why there are days and nights on the earth!"

"These viewpoints of the Marquis of Yong'an are unconvincing! I heard that a general in the Taishi Bureau used an astronomical telescope to observe the stars all day in the Yanhuang Academy. These views! Now that they have been said, they can definitely be proved with astronomical telescopes!"

"That's right! That's right! Marquis Yong'an is pedantic, since he dares to say that, and he has so much evidence in his hands, it means that these are all true! I believe Marquis Yong'an's statement!"

"I believe it too! And I finally understood why there is a tengu eclipse today. It turns out that the moon is blocking the sun's rays shining on the earth! In the past, people regarded the tengu eclipse as a big omen. Now it seems that, It's so ridiculous!"

There is a lot of public discussion about Li Zexuan's article, some criticize and doubt it, and some strongly support it. The reason is mainly the views put forward by Li Zexuan. The arguments are very sufficient, and it reasonably explains many problems that could not be explained before. A few illustrations, it's easy to convince!

At this time, Li Zexuan had to rejoice that he was an "engineering dog" in his previous life, because the most important thing for engineering students to write papers is to have clear logic and sufficient arguments and data.

This rigorous academic quality enables him to write popular science articles that are completely different from the style of writing in this era, but can persuade most people well!

Besides, Li Zexuan put on a posture of "If you don't believe me, come to Yanhuang Academy to see for yourself with a telescope", this strong confidence has to be convincing!

Of course, Li Zexuan's lofty prestige in the folk and academic circles has also played a considerable positive role in it. Even though engineering has not been widely recognized and become a mainstream theory, there are already many scholars in the public who admire Li Zexuan very much. !

Under the blessing of various reasons, there are not a few people who believe in Li Zexuan's solar system theory.

…………………………

In the palace, after Li Er finished the morning court, Zhao Song handed over today's "Datang Daily" to Li Er, because he was also present when Li Chunfeng faced the Holy Spirit yesterday, so he saw what Li Zexuan wrote in today's "Datang Daily" After that article, he immediately understood Li Zexuan's intention, and in his opinion, Li Er must be happy to read this article!

"Solar system? Planets? Solar eclipse? After this kid said that, the dog eclipse day doesn't seem to be a bad thing! Well, he is trying to reduce the impact of the dog eclipse sun on the people two days later. It's really hard for this kid! "

After seeing the theory of the solar system in the newspaper and Li Zexuan's explanation on the cause of the eclipse of the sun, Li Er also understood Li Zexuan's intention, and he couldn't help but sigh in his heart.

"I ordered Li Chunfeng of the Taishi Bureau to compile a manuscript of the results he observed with the telescope in the Yanhuang Academy in the past six months, and published it in the "Datang Daily" in the name of the imperial court. Let the people completely believe in Li Zexuan's theory of the solar system and the explanation of the cause of the eclipse of the sun!"

After thinking for a moment, Li Er ordered.

Li Chunfeng had borrowed astronomical telescopes from Yanhuang Academy for so long, so naturally he did not find anything. Regarding the planetary orbits in the solar system, Li Chunfeng drew a star map as early as the beginning of this year and secretly showed it to Li Er. So now Li Er won't be so surprised when he sees Li Zexuan's theory!

Li Er was not afraid of the rumors of the people during the solar eclipse, and did not plan to make arrangements in advance to deal with it, but now that Li Zexuan helped him, he naturally didn't mind to push the boat and provide Li Zexuan with an official copy. In order to make more people believe in Li Zexuan's theory!

Zhao Song understood: "Here! Your Majesty! This old slave will go to the Taishi Bureau to pass the decree!"

………………

The influence of Li Zexuan's solar system theory is not small at all. After the news reached the Japanese mission, the Shanbei eldest brother Wang earnestly read the "Overview of Astronomy" more than ten times. At the end, he couldn't help but sigh:

"The Marquis of Yongan is really pedantic. This theory is unheard of, but it's so well-founded that it's hard for people to believe it or not! I think when our Japanese people were still worrying about food and clothing, The Marquis of Yongan has already set his sights on Qiongyu, with such knowledge and mind, no one in the world can match him! If he can be used by the Japanese country, then why can't the Japanese country prosper beyond the Tang Dynasty!"

After sighing for a while, he looked at his subordinates and asked, "Kamiki Ishikawa, how is our football team training?"

After Yoko Ono died last time, there was one less person around him who was always there for him. Now he was the head of the guards, taking over from Yoko Ono!

"Go back to His Royal Highness! The recent training progress of the football team is very good! We have learned the tactics of the top teams in Datang, and now the cooperation between the players has been very tacit. A few days ago, we privately talked to a few Only the Tang Jia team competed, and they all won! My subordinates feel that we can fight against the best team in Datang and win it!"

Kamiki Ishikawa is a Japanese warrior in his thirties. Although he is not burly, his body seems to be full of strength, which is not to be underestimated. At this time, he respectfully reported to the eldest brother Wang Shanbei. road.

Shanbei eldest brother Wang said with satisfaction: "Okay! When the Datang Football Federation's league is over, I will go to see the Emperor of the Tang Dynasty alone and ask for a match with their most powerful team. The Tang people are good-natured, and the Emperor of the Tang Dynasty will definitely agree. If we win, maybe the Emperor Tang can accept our conditions, and in the future, the Japanese country will be able to send foreign students to Yanhuang Academy to learn advanced knowledge!"

(The term “student students” originated from the cultural exchange between China and Japan during the Tang Dynasty in China, meaning Japanese students who stayed in China to study after returning to China as envoys from the Tang Dynasty.

This guy really has a good abacus, and he has never given up on the engineering knowledge of Yanhuang Academy!

As the so-called bystander is clear, when the people of Tang Dynasty were still fighting each other over Confucianism and engineering, the outsider Wang Shanbei had already seen that engineering was more practical than Confucianism. He even felt that engineering could make a country invincible to the world! He very much hopes that the Japanese state can one day surpass all countries in the world, so his obsession with Li Zexuan and Yanhuang Academy is very, very deep!

But in such a powerful country as the Tang Dynasty, he did not dare to reveal the ambition hidden in his heart at all. He knew that the most important thing now is to keep a low profile, forbearance, and development!

……………………

On this day, in addition to the heated discussion of the solar system theory, another major event happened, that is, the Bahe dam finally began to store water!

"Master Hou! All the gates have been closed, and the current water level is 7:50!"

"Master Hou! An hour has passed, and the water level has risen to ten feet!"

"Master Hou

! Two hours have come, and the water level has risen to twelve feet! "

"Master Hou! Three hours have come, and the water level has risen to 13 feet!"

Starting from the morning, all the gates of the dam have been put down, and the diversion canals built before have also been blocked. The water level in the upper reaches of the Ba River is constantly rising. Fortunately, there are no people living near the riverbed in the upper reaches of the river. Otherwise, there is a risk of flooding!

Listening to the reports from the craftsmen again and again, Li Zexuan's heart was not completely relieved because of this, because the further the water level rose, the more difficult it was to rise. The water level of a mere ten feet could not meet the needs of a county in Lantian County!

"Shangchang, there should be some time before the severe drought, you don't have to worry about it! In the later period, as long as there is rain in the upper reaches of the river, the water level of the Bahe dam will easily break through to more than twenty-five feet. , then it should be enough for the people of Lantian County!"

Seeing that Li Zexuan had been frowning, Mo Huai couldn't help but comfort him.

Li Zexuan nodded and said: "Now we can only wait slowly! Mr. Mo, you are busy first, I will go back and see if there is any other way!"

…………………………

Day two.

"Datang Daily" published another article on the theory of the solar system. The difference is that the signature of this article includes important officials of the entire Taishi Bureau. The results observed with the astronomical telescope are completely consistent with the article by Li Zexuan yesterday.

As soon as this article came out, the common people were in an uproar again, because this is basically equivalent to the court's platform for Li Zexuan's solar system theory!

Since then, the theory of the solar system has gained a firm foothold, and the explanation of the cause of the Tengu Eclipse can be regarded as an advance preparation and prevention for the Tengu Eclipse one day later!
