Otaku Engineer in Great Tang Dynasty

(Two-in-one chapter)

The next day, "Datang Daily" published an article 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 about the solar system. Concept, he pointed out that the sun is a star, the earth under our feet is called the earth, which is a planet in the solar system, and there are five major planets in the solar system: gold, wood, water, fire, and earth. All planets in the solar system surround the sun. turn!

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, it takes about 27 days, about one month, so every month the moon will be cloudy and clear; besides, the earth will also Rotation, the rotation cycle is almost one day, so people can see sunrise and sunset, day and night every day!

In addition, in this article, Li Zexuan 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’s light from the earth. , The black shadow behind the moon just fell on the earth, at this time a solar eclipse will occur.

　　 In order to better allow readers to understand what he said in the article, he also included some simplified diagrams of the trajectories of stars. Basically, anyone who can read characters can understand the cause of the solar eclipse! ,

　　 Finally, Li Zexuan declared that all the above-mentioned contents 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, and earth) instead of the eight planets, it is mainly because the stars of the other two planets (Uranus and Neptune) are relatively dim and orbiting. Slowly and at the edge of the solar system, the telescope of Yanhuang Academy cannot observe it, 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 and 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, the occurrence of the Tengu eclipse day has been regarded as a sign that the monarch is faint and the country is about to die, causing the people to panic. Li Zexuan wants to tell the people in advance that the Tengu eclipse day is just a normal astronomical phenomenon. It didn't matter whether the emperor was faint or not.

As soon as this article was published in the "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. In many ancient myths and stories, there are special meanings. 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 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!"

"Nor say that Yong'an Hou is nonsense! Because according to Yong'an Hou's point of view, we have four seasons of spring, summer, autumn, and winter that can be explained each year! Far from the sun is winter, and closer to the sun is summer! A year is a cycle, and it is also a revolution cycle!"

　　 "And Yonganhou's view of "the earth can still rotate" is also very unique, because if the rotation cycle of the earth is one day, it can explain why there will be day and night on the earth!"

"These views of Yong'an Hou are convincing! I heard that a general of the Taishi Bureau used astronomical telescopes to observe stars at Yanhuang Academy all day long. If there is no evidence, Yong'an Hou would definitely not dare to say so confidently. These points! Now that I have said them, they can definitely be proved by astronomical telescopes!"

　　 "That's right! That's right! Yonganhou is a scholar of heaven and human beings. Since he dares to say so, and he has so many evidences in his hands, it shows that these are true! I believe Yonganhou's statement!"

"I believe it too! And today 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 great omen. Now it seems, It's so ridiculous!"

There are many discussions among the people 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 many problems that could not be explained before are reasonably explained. The sub-illustration is easily convincing!

At this time, Li Zexuan had to be fortunate 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 accomplishment that he can write Produce popular science articles that are very different from the writing style of 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 watch it yourself with a telescope." This powerful confidence is even more convincing!

Of course, Li Zexuan’s lofty prestige 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 who admire Li Zexuan very much. !

　　Under the blessing of 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!

　　.........................

In the imperial palace, after Li Er’s morning dynasty, Zhao Song handed over today’s "Datang Daily" to Li Er. Because he was also present when Li Chunfeng faced the saint yesterday, so he saw what Li Zexuan wrote in the "Datang Daily" today. After that article, I 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 didn't seem to be a bad thing! He wanted to reduce the influence of the eclipse day on the people in the future. It's really hard for this kid!"

　　 After reading the theory of the solar system in the newspaper and Li Zexuan's explanation on the cause of the Tengu eclipse, Li Er also understood Li Zexuan's intention, and he couldn't help but sigh 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. Let the people completely believe in Li Zexuan's solar system theory and the explanation of the cause of the Tengu eclipse!"

　　 After thinking for a moment, Li Er ordered.

Li Chunfeng borrowed the astronomical telescope from Yanhuang Academy for so long, naturally, he didn’t find anything. 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. 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 Li Zexuan with an official In order to make more people believe in Li Zexuan’s theory!

　　 Zhao Songxin knew how to say: "Hey! Your Majesty! The old slave will go to the Taishi Bureau to deliver the decree!"

　　...........................

　　 Li Zexuan’s solar system theory has not little influence at all. After the news reached the Japanese mission, Brother Shanbei carefully read the "Overview of Astronomy" a dozen times. At the end, he couldn't help but sigh with emotion:

"Hou Yongan is really a scholar of heaven and man. This theory is unheard of, but what is said above is so reasonable and well-founded. It is hard to believe it! When the people of the Japanese country are still worried about food and clothing, Yonganhou But he has already set his sights on Qiongyu. With such knowledge and such a mind, no one in the world can match! If he can be used by the Japanese kingdom, then why don't I worry about the Japanese kingdom prospering over the Tang Dynasty!"

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

　　 After the death of Yoko Ono last time, he was missing a person 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 has been very tacit. A few days ago, we privately Only the Tang A team competed and they all won! The subordinates feel that we can fight and win 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 makes one dare not to underestimate him. At this time, he respectfully reported to Shanbei King. Tao.

Brother Shanbei said with satisfaction: "Okay! Once the League of the Datang Football Association 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 and the Emperor of the Tang Dynasty will definitely agree. If we win, maybe the Emperor of Tang Dynasty will be able to accept our conditions, and in the future, 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. It means Japanese students who stayed in China to study after being sent to the Tang Dynasty. In modern times, they generally refer to students who live abroad for study or research)

　　 This product is really a good calculation, he has not 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 because of Confucianism and engineering, the outsider, the Shanbei brother, had already seen that engineering is more practical than Confucianism, and even he faintly felt that engineering can make a country invincible in the world! He very much hopes that the U.S. country can surpass all the countries in the world one day, so his obsession with Li Zexuan and Yanhuang Academy is very, very deep!

　　 But in a country as powerful 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 has caused heated discussions among the people, another major event has occurred, that is, the Bahe Dam finally began to store water!

　　 "Master Hou! All the gates have been closed, and the current water level is seven and 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, and the water level has risen to 13 feet!"

Beginning in the morning, all the gates of the dam were lowered, and all the diversion channels built before were blocked. The water level in the upper reaches of the Bahe River is constantly rising. Fortunately, there are no people living near the riverbed in the upper reaches of the river. Otherwise, there is a danger of being flooded!

Listening to the reports from the craftsmen~www.readwn.com~Li Zexuan's heart was not completely relieved, because the water level rose more difficultly as the water level rose to the back, and the water level of a mere ten feet could not satisfy the Lantian county. What the county needs!

"The mountain is long, and there should be some time away from the severe drought. You don't need to be anxious for a while! In the later 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 above 25 feet. , It should be enough for the people of Lantian County!"

　　 Seeing Li Zexuan frowning, Mo Huai couldn't help but comforted.

　　Li Zexuan nodded and said: "Now I can only wait slowly! Mr. Mo, you are busy first, I will go back and think about any other ways!"

　　.........................

　　 The next day.

"Datang Daily" published an article on solar system theory. The difference is that the signature of this article included important officials from the entire Taishi Bureau. The article described in detail that the Taishi Bureau's official Li Chunfeng has been in the past six months. The results observed with the astronomical telescope are in full agreement with the article by Li Zexuan yesterday.

　　As soon as this article came out, public opinion was in an uproar again, because it was basically equivalent to 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 eclipse of the Tengu is a precaution for the eclipse of the Tengu one day later!
