Otaku Engineer in Great Tang Dynasty Chapter 1391: The solar system!
(Two-in-one chapter)
The next day, "Datang Daily" published a news written by Li Zexuan, called "Astronomy Overview". This is an article to popularize basic astronomy knowledge to the public. In the article, Li Zexuan formally proposed to the public In order to understand the concept of the solar system, he pointed out that the sun is a star, and the earth under our feet is called the earth. It is a planet in the solar system, and there are five major planets in the solar system: gold, wood, water, fire, and earth. Revolve around the sun!
At the same time, he also pointed out that the earth revolves around the sun for a week, and it takes about three hundred and sixty-five days, which is what people often call a year, so people can feel the changes of the four seasons in a year. ; The moon is the satellite of the earth, it will revolve around the earth, and the time required for one revolution is about 27 days, which is about one month, so every month the moon will be cloudy and sunny; besides, The earth also rotates, and the rotation cycle is almost one day, so people can see the sun rising and sunset, day and night every day!
In addition, in this article, Li Zexuan also explained to the public the cause of the Tengu eclipse phenomenon, that is, the moon moves between the sun and the earth. If the three are exactly in a straight line, the moon will block the sun from shooting. The light of the earth and the black shadow behind the moon just fall on the earth, and a solar eclipse will occur at this time.
In order to better allow readers to understand what he said in the article, he also included some simple diagrams of the trajectories of stars. Basically, anyone who can read characters can understand the cause of the solar eclipse after reading it! ,
Finally, Li Zexuan stated that the above-mentioned content can be observed and proved by the telescope of Yanhuang Academy.
As for why he only proposed the six planets in the solar system (gold, wood, water, fire, earth, earth) instead of the eight planets, it is mainly because the stars of the other two planets (Uranus and Neptune) are relatively dim , Orbiting slowly, and at the edge of the solar system, the telescope of Yanhuang Academy cannot observe, so he can only tell people that there are six planets in the solar system!
In fact, the ancients mentioned several planets in the solar system in astrology. The most important content in astronomical observations is the "five stars, seven politics". 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 Governments" means adding the sun and moon to the "five stars" .
So the concept of the six planets in the solar system proposed by Li Zexuan is well understood! Coupled with the supporting testimony of the telescope of Yanhuang Academy, this theory is even more convincing!
And Li Zexuan personally wrote this article to give people a vaccination in advance for the Tengu eclipse day vision that will appear two days later.
Since ancient times, once the Tengu Eclipse Phenomenon appears, it has been regarded as a sign of the monarch’s fainting and the country’s dying, making the people panic. Li Zexuan wanted to tell the people in advance that the Tengu Eclipse is just a normal astronomy. This phenomenon has nothing to do with the emperor's faintness.
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 it is like the moon and the sun. Such stars 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. It is refreshing and the people are also shocked!
"What? The earth under our feet is spherical? And it still revolves around the sun?"
"Look at this picture, there are five other planets that revolve around the sun just like the earth?"
"Nonsense! Total nonsense! How could the land under our feet be spherical? Also, how could the land under our feet revolve around the sun? Isn’t the sun revolving around us? That’s why we Will see day and night!"
"You can’t say that Yonganhou is nonsense! Because according to Yong’anhou’s point of view, we have four seasons of spring, summer, autumn, and winter that can be explained each year! Far away from the sun is winter, and closer to the sun It’s summer! A year is a cycle, and it also happens to be a revolution cycle!"
"And Yonganhou's view of "the earth can still rotate" is also unique, because if the earth's rotation cycle is one day, it can explain why day and night appear on the earth!"
"These views of Yonganhou are compelling! I heard that a general of the Taishi Bureau used astronomical telescopes to observe stars at Yanhuang Academy. If there is no evidence, Yonganhou would definitely not be so sure. Say these points! Now that they are said, they can definitely be proved by astronomical telescopes!"
"Yes! That's right! Yong'an Hou is pedantic, since he dares to say that, and he has so many evidences in his hands, it shows that these are true! I believe Yong'an Hou's statement!"
"I believe it too! And I finally understand why there is a Tengu Eclipse Day. It turned out that the moon blocked the sun shining on the earth! People in the past regarded the Tengu Eclipse Day as a big bad omen. Now It seems so ridiculous!"
There are a lot of people talking about Li Zexuan’s article, both critically and skeptical, and strongly supported. The main reason is the viewpoints put forward by Li Zexuan. The arguments are very sufficient and explain many problems that could not be explained before. With a few illustrations, it is easy to be convincing!
At this time, Li Zexuan had to be thankful 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, sufficient arguments and data. It is based on this rigorous academic quality that makes He can write popular science articles that are very different from the style of this era, but can persuade most people well!
Furthermore, Li Zexuan put on a posture of "If you don't believe me, come to Yanhuang Academy and watch it yourself with a telescope." This powerful confidence is even more convincing!
Of course, now Li Zexuan’s high reputation in the civil and academic circles has also played a considerable positive role in it. Even though engineering has not been widely recognized and has become the mainstream doctrine, there are already many scholars in the civil society who have regarded Li Zexuan. I really admire it!
Thanks to various reasons, there are not a few people who believe in Li Zexuan. Since then, the theory of the solar system has been decapitated for the first time in Datang, and it has succeeded for the first time!
.........................
Imperial Palace, after Li Er’s morning dynasty, Zhao Song handed over today’s "Datang Daily" to Li Er, because he was also there when Li Chunfeng faced the saint yesterday, so he saw today’s "Datang Daily" After Li Zexuan wrote that article, he immediately understood Li Zexuan's intentions, and in his opinion, Li Er must be happy to read this article!
"Solar system? Planets? Solar eclipse? When this kid said that, the dog eclipse day did not seem to be a bad thing! He wanted to reduce the influence of the eclipse day on the people in the future. It is really hard for this kid. !"
After reading the theory of the solar system in the newspaper and Li Zexuan's explanation of the cause of the Tengu eclipse, Li Er also understood Li Zexuan's intentions, and he couldn't help feeling in his heart.
" With Li Chunfeng of the Taishi Bureau, he compiled a manuscript of the results he observed with the telescope at Yanhuang Academy over the past six months and published it in the "Datang Daily" in the name of the court. To the public, let the people completely believe in Li Zexuan's solar system theory and the explanation of the cause of the eclipse of the Tengu!"
thought for a moment, Li Er ordered.
Li Chunfeng borrowed the astronomical telescope at Yanhuang Academy for so long, naturally, he would not have found nothing. Regarding the planetary trajectory map of the solar system, Li Chunfeng drew a copy as early as the beginning of this year and secretly showed it to Li Er. It's over, so now Li Er sees Li Zexuan's theory, he won't seem so surprised!
And Li Er was originally not afraid of the rumors of the people during the solar eclipse, and did not plan to make arrangements to deal with it in advance, but now that Li Zexuan helped him do it, he naturally didn’t mind coming along and providing it to Li Zexuan An official piece of evidence to make more people believe in Li Zexuan's theory!
Zhao Songxin knows how to say: "Hey! Your Majesty! The old slave will go to the Taishi Bureau to pass on the decree!"
...........................
Li Zexuan’s theory of the solar system has not a small impact at all. After the news reached the Japanese mission, Brother Shanbei carefully read the "Overview of Astronomy" over a dozen times. At the end, he couldn't help but sigh with emotion. :
"Hou Yongan is really pedantic. This theory is unheard of, but the above statement is so reasonable and well-founded, it is hard for people to believe it! When the Japanese people were still worried about food and clothing However, Yonganhou has already set his sights on Qiongyu. With such a knowledge and such a mind, no one in the world can match! If he can be used by the Japanese country, then why should I worry about the Japanese country not prospering over the Tang Dynasty! "
sighed for a while, he looked at his subordinates and asked: "Ishikawa Kamiki, how is our football team training?"
The last time Yoko Ono died, there was one less person around him who was waiting at any time. He is now the head of his bodyguard, taking over the position of Yoko Ono!
"Return to Your Highness! The football team’s recent training progress is very good! We have learned the tactics of the top teams in Datang, and now the cooperation between the players is very tacit. A few days ago, we Privately competed against several Tang A teams, and they all won! The subordinates feel that we can fight and win against the best team in Datang!"
Ishikawa Kamiki is a 30-year-old Japanese warrior. Although he is not burly, his body seems to be full of power, which is not to be underestimated. At this time, he respectfully faces the mountain back. Brother Wang Hui reports.
Shanbei 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 and ask for a match with their best team. The Tang people are good-faced, the Emperor of the Tang Dynasty. We will definitely agree! If we win, maybe the Emperor of Tang Dynasty will be able to accept our conditions, and the Japanese will be able to send overseas students to Yanhuang Academy to learn advanced knowledge!"
(The term “student abroad” originated from the cultural exchanges between China and Japan during the Tang Dynasty in China. It means Japanese students who stayed in China to study after being sent to the Tang Dynasty. In modern times, it generally refers to students who live abroad for study or research)
This product is really a good calculation, he has never given up on the engineering knowledge of Yanhuang Academy!
is the so-called bystander clear. When the people of Tang Dynasty were still fighting with each other over Confucianism and engineering, the outsider, Shanbei, had already seen that engineering is more practical than Confucianism. He even faintly felt that engineering can make a country invincible in the world. ! He very much hopes that the U.S. country will be able to surpass all countries in the world one day, so his obsession with Li Zexuan and Yanhuang Academy is very, very deep!
But in a country as strong as Datang, he dare not show his hidden ambitions at all. He knows that the most important thing now is to keep a low profile, tolerate, and develop!
........................
On this day, in addition to the solar system theory that aroused popular debate among the people, another major event happened, that is, the Bahe Dam finally started to store water!
"Master Hou! All gates have been closed, and the current water level is seven to five feet!"
"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, the water level has risen to 13 feet!"
Since the morning, all the gates of the dam have been lowered, and all the diversion channels built before have been blocked. The water level in the upper reaches of the Bahe River is constantly rising. Fortunately, there is no If the people live, they will be in danger of being flooded!
Listening to the reports from the craftsmen~IndoMTL.com~Li Zexuan's heart is not completely relieved because the water level rises more difficultly as the water level rises to the back. The water level of a mere ten feet can not satisfy Lantian County. What a county needs!
" The mountain is long, and there should be some time away from the severe drought. You don’t have to worry about it for a while! In the latter period, as long as there is a rain in the upper reaches of the river, the water level of the Bahe Dam can easily break through to 20 More than five feet, it should be enough for the people of Lantian County by then!"
Mo Huai saw Li Zexuan frowning all the time, and couldn't help but comforting.
Li Zexuan nodded and said: "Now I can only wait slowly! Mr. Mo, you are busy, I will go back and think about any other way!"
..........................
the next day.
"Datang Daily" published an article on solar system theory. The difference is that the signature of this article included important officials of the Taishi Bureau. The article detailed the introduction of Li Chunfeng The results observed with astronomical telescopes in the past six months are in full agreement with the article by Li Zexuan yesterday.
As soon as this article was published, public opinion was in an uproar again, because it was basically the equivalent of the imperial court serving Li Zexuan's solar system theory platform!
Since then, the theory of the solar system has gained a firm foothold, and the explanation of the cause of the Tengu eclipse day can be regarded as an advance prevention for the Tengu eclipse day one day later!
