(Two in one chapter)
The next day, "Datang Daily" published an article written by Li Zexuan called "Astronomy Overview". This was an article to popularize basic astronomical knowledge to the public. In the article, Li Zexuan formally proposed to the public the introduction of 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. There are also five planets in the solar system: gold, wood, water, fire, and earth. All the planets in the solar system revolve around the sun. change!
At the same time, he also pointed out that the time it takes for the earth to revolve around the sun is about 365 days, which is often called a year, so people can feel the changes of the four seasons in a year; the moon is The earth's satellite will revolve around the earth. The time it takes for one revolution is about twenty-seven days, which is about one month. Therefore, the moon will wax and wane 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, Li Zexuan also explained to the public the cause of the Tengu solar eclipse phenomenon, that is, the moon moves between the sun and the earth. If the three happen to be in a straight line, the moon will block the sun's light from the earth. , the dark shadow behind the moon happens to fall on the earth, and a solar eclipse will occur.
In order to better let readers understand what he said in the article, he also included some simple diagrams of the orbits of the stars. Basically, anyone who can read can understand the causes of solar eclipses after reading it! ,
Finally, Li Zexuan declared that all the above can be observed and proved using the telescope of Yanhuang Academy.
As for why he only proposed the six major planets in the solar system (gold, wood, water, fire, earth, and earth) instead of the eight major planets, it was mainly because the other two planets (Uranus and Neptune) were relatively dim and orbiting. It's slow, and it's at the edge of the solar system. It can't be observed by Yanhuang Academy's telescope, so now he can only tell people that there are six major planets in the solar system!
In fact, the ancients mentioned several major planets in the solar system in astrology. The most important content in astronomical observation is the "five stars and seven states." The so-called "Five Stars" refer to the five planets visible to the naked eye: "Mercury", "Venus", "Mars", "Jupiter" and "Saturn"; the so-called "Seven Stars" are the addition of the sun and moon to the "Five Stars" .
Therefore, the concept of the six planets in the solar system proposed by Li Zexuan is still easy to understand! Coupled with the supporting evidence of the telescope of Yanhuang Academy, this theory becomes even more convincing!
Li Zexuan's intention in writing this article himself was to inoculate the public in advance against the Tengu eclipse phenomenon that will appear in two days.
Since ancient times, once the phenomenon of Tengu eclipsing the sun occurs, it is regarded as a sign that the monarch is ignorant and the country will be destroyed, making the people panic. Li Zexuan wanted to tell the people in advance that the Tengu eclipse is just a normal astronomical phenomenon. It doesn't matter whether the emperor is stupid or not.
As soon as 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 stars like the moon and the sun are , have special meanings in many ancient myths and stories. Now Li Zexuan has unveiled the mystery of these stars and formally proposed the concept of the solar system. While it is refreshing, the people are also shocked!
"What? The earth under our feet is spherical? And it also revolves around the sun?"
"Look at this picture, there are five other planets that also revolve around the sun like the earth?"
"Nonsense! Complete nonsense! How could the land under our feet be spherical? Also, how could the land under our feet revolve around the sun? Doesn't it mean that the sun revolves around us? It is precisely because of this that we see day and night!"
"You can't say that Marquis Yong'an is talking nonsense! Because according to Marquis Yong'an's point of view, it can be explained that we have four seasons of spring, summer, autumn and winter every year! Winter is when we are farther from the sun, and summer when we are closer to the sun! One year is a cycle, which also happens to be a revolution period!”
"Furthermore, Marquis Yong'an's view that the earth can still rotate is also very unique, because if the earth's rotation period is one day, it can exactly explain why there are day and night on the earth!"
"These views of Marquis Yong'an are so convincing! I heard that a general from the Taishi Bureau used an astronomical telescope to observe stars all day long in Yanhuang Academy. Without evidence, Marquis Yong'an would not dare to say this with such certainty. These views! Now that they are stated, they can definitely be proven using astronomical telescopes!"
"That's right! That's right! Marquis Yong'an is a scholar of heaven and earth. Since he dares to say this and has so much evidence in his hands, it shows that these are true! I believe what Marquis Yong'an says!"
"I believe it too! And I finally understood why there is a Tengu eclipse today. It turns out that the moon blocks the sunlight that shines on the earth! People in the past regarded the Tengu eclipse as a sign of great misfortune. But now it seems, So ridiculous!"
There are a lot of discussions among the people about Li Zexuan's article, some are critical and skeptical, and some are full of support. The main reason is the views raised by Li Zexuan. The arguments are very sufficient, and they reasonably explain many problems that could not be explained before. With a few The illustrations are easily convincing!
At this time, Li Zexuan had to be grateful that he was an "engineering dog" in his previous life, because the most important thing for engineering students to write papers is clear logic, sufficient arguments and data. It is based on this rigorous academic quality that he can write A popular science article that is very different from the writing style of this era, but can persuade most people very well!
Besides, Li Zexuan put on a posture of "If you don't believe it, come to Yanhuang Academy and use the telescope to see for yourself." This strong confidence is even more convincing!
Of course, Li Zexuan's high reputation among the people and academia now also plays a considerable positive role in it. Even though engineering has not yet been widely recognized and has become a mainstream theory, many scholars among the people already admire Li Zexuan very much. !
Due to various reasons, there were not a few people who believed in Li Zexuan. From then on, the theory of the solar system first appeared in the Tang Dynasty and achieved initial success!
.............................
In the palace, after Li Er went to the morning court, Zhao Song handed today's "Datang Daily" to Li Er. Because he was also present when Li Chunfeng met the saint yesterday, he saw what Li Zexuan wrote in today's "Datang Daily" After reading that article, he immediately understood Li Zexuan’s intention, and in his opinion, Li Er would definitely be happy to read this article!
"Solar system? Planet? Solar eclipse? After this boy said this, it seems that the dog's eclipse that day is not a bad thing! He is trying to reduce the impact of the dog's eclipse on the people the day after tomorrow. It is really difficult for this boy!"
After seeing the solar system theory in the newspaper and Li Zexuan's explanation about the cause of the Tengu eclipse, Li Er also understood Li Zexuan's intention, and he couldn't help but sigh in his heart.
"Order Li Chunfeng of the Taishi Bureau to compile a manuscript based on the results he has observed using telescopes at Yanhuang Academy over the past six months, and make it public 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 Tengu eclipse!”
After thinking for a moment, Li Er ordered.
Li Chunfeng had borrowed the astronomical telescope at Yanhuang Academy for so long, so it was natural that he would not have discovered anything. As for the planetary trajectory diagram of the solar system, Li Chunfeng had drawn a copy of it as early as the beginning of this year and secretly presented it to Li Er. So now Li Er won't be so surprised when he sees Li Zexuan's theory!
Li Er was originally not afraid of folk rumors during the solar eclipse, and had no intention of making arrangements in advance to deal with them. But now that Li Zexuan has done it for him, he naturally doesn't mind going along and providing Li Zexuan with an official report. evidence to make more people believe in Li Zexuan’s theory!
Zhao Song understood and said: "Here! Your Majesty! This old slave will go to the Taishi Bureau to deliver the order!"
.............................
Li Zexuan's theory of the solar system had a considerable impact. After the news reached the Japanese mission, Shanbei's eldest brother, Wang, read the "Astronomical Overview" seriously for more than a dozen times. At the end, he couldn't help but sigh:
"Marquis Yong'an is really a scholar. I have never heard of this theory, but it is so well-founded that it's hard not to believe it! When the people of Japan were still worrying about food and clothing, Marquis Yong'an But he has already set his sights on Qiong Yu. With such knowledge and such a big heart, no one in the world can match him! If he can be used by the Japanese country, then why should we, the Japanese country, not be able to prosper more than the Tang Dynasty!"
After sighing for a while, he looked at his subordinates and asked: "Ishikawa Kamiki, how is the training of our football team?"
After Yoko Ono died last time, there was one less person around him who could always serve him. Now he is his original head of bodyguards, taking over Yoko Ono's position!
"Back to Your Highness! The recent training progress of the football team is very good! We have studied the tactics of several top-ranked teams in Datang. Now the cooperation between the players is very tacit. A few days ago, we privately talked to a few Only Tang A teams competed, and all of them won! My subordinates feel that we can compete with the best team in Tang Dynasty and win!"
Ishikawa Kamiki is a Japanese warrior in his thirties. Although he is not tall, his body seems to be full of strength, which makes people dare not underestimate him. At this time, he respectfully reported to the eldest brother Yamabei road.
Shanbei's eldest brother Wang said with satisfaction: "Okay! As soon as the Tang Football Association's league is over, I will go to see the Emperor of the Tang Dynasty and ask for a match with their most powerful team. The Tang people are good at face, and the Emperor of the Tang Dynasty will definitely agree. ! If we win, maybe the Emperor of the Tang Dynasty will be able to 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 "foreign students" originated from the cultural exchanges between China and Japan during the Tang Dynasty in China, meaning Japanese students who stayed in China to study after the envoys sent to the Tang Dynasty returned to China. In modern times, it generally refers to students who stay abroad to study or research)
This guy is really good at calculating. He has never given up on the engineering knowledge from Yanhuang Academy!
As the saying goes, bystanders know better. When the Tang Dynasty people were still fighting each other over Confucianism and engineering, Shanbei's eldest brother Wang, an outsider, had already seen through that engineering was more practical than Confucianism. He even vaguely felt that engineering could make a country invincible in the world! He very much hopes that the Japanese country will one day be superior to all countries in the world, so he has a very, very deep obsession with Li Zexuan and Yanhuang Academy!
But in a country as powerful as the Tang Dynasty, he did not dare to reveal his hidden ambitions at all. He knew that the most important thing now was to keep a low profile, be patient, and develop!
............................
On this day, in addition to the solar system theory arousing heated discussion among the people, another major event also happened, that is, the Bahe Dam finally began to store water!
"Master Hou! All gates have been closed, the current water level is 7.5 feet!"
"Master Hou! An hour has passed and the water level has risen to ten feet!"
"Master Hou! Two hours have passed and the water level has risen to twelve feet!"
"Master Hou! Three hours have passed and the water level has risen to thirteen feet!"
Starting at 6 o'clock in the morning, all the gates of the dam were lowered, and all the previously built diversion canals were blocked. The water level in the upper reaches of the Bahe River continued to rise. Fortunately, there were no people living near the riverbed in the upper reaches. Otherwise, there is a risk of being flooded!
Listening to the reports from the craftsmen again and again, Li Zexuan was not completely relieved because the water level became more difficult to rise as it reached the back. The water level of only a dozen feet could not meet the needs of a county in Lantian County!
"The mountain is long. There should be some time before a severe drought. You don't have to worry about it! In the next period of time, as long as it rains in the upper reaches, the water level of the Bahe Dam will easily exceed 25 feet. , it should be enough for the people of Lantian County by then!"
Seeing Li Zexuan frowning all the time, Mo Huai couldn't help but comfort him with gentle words.
Li Zexuan nodded and said: "Now we can only wait slowly! Mr. Mo, you work first, I will go back and think about other solutions!"
............................
The second day.
"Datang Daily" published another article on the theory of the solar system. The difference is that the signatures of this article include important officials from the Taishi Bureau. The article details the work of Li Chunfeng, the general of the Taishi Bureau, in the past six months. The results observed with astronomical telescopes are completely consistent with Li Zexuan's article yesterday.
As soon as this article came out, public opinion was in an uproar again, because this is basically equivalent to the court supporting Li Zexuan's solar system theory!
Since then, the solar system theory has gained a firm foothold, and the explanation of the cause of the Tengu eclipse can be regarded as an early prevention for the Tengu eclipse in the future!
