Wang Haoran is in a good mood these days, because Xu Xuanan sent a few days ago about the situation of miscellaneous rice cultivation in the country, and judging from the current situation, the yield of three stones per mu can be expected. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 info Wang Haoran counted the time spent researching miscellaneous rice and found that he had unknowingly studied it for seven or eight years! This is still the result of the experience of later generations!

The day of Enke's first round of screening was approaching, and Wang Haoran decided to go back to Chang'an as soon as possible, because Fan Qiusi was about to give birth and wanted to get things done as soon as possible and come back to meet his third child.

After Wang Haoran returned to Chang'an, he only needed to go directly to the Hanlin Academy to read the papers. At this time, the Hanlin Academy was not a fragrant bun, just a group of people with some artistic abilities, and the reason why Li Shimin asked people to send the examination papers to the Hanlin Academy was because the Hanlin Academy was not infiltrated by the imperial court.

The people of the Hanlin Academy admired Wang Haoran very much, especially after the opening of the steam-powered car, and almost regarded Wang Haoran as a pioneer. Wang Haoran felt a little strange, and after some small talk, he realized that these people were originally idle, and since Wang Haoran led people to measure the moon, they were a little interested in this world, and they discussed this aspect with each other when they had time. After much discussion, the question came, and they wondered, if this side of the world is really as depicted in the armillary theory, then when the sun turns to the bottom of the earth, can it also be like day? The earth floats on the water, so how does it do it? It's common knowledge that dirt sinks to the bottom! What does the end of the earth look like? The abyss? Or the boundless sea?

Wang Haoran was asked a series of questions by these people and didn't know how to answer for a while, you know, the world's cosmology is very similar to the earth's circle, just because he thinks that it is impossible to stand on the end of the earth, and he can't think of the earth as spherical. In fact, relatively speaking, the armillary theory can completely solve the problems that can be encountered at present, such as why the sea surface is arc-shaped, the sun, moon and stars, and other phenomena, although Wang Haoran comes from later generations, but there is no good way to prove that the earth is round. Even so, if it is an academic study or to broaden the imagination of the people, Wang Haoran feels that it is not inappropriate to put forward the theory of the earth at this time. If it was before, Wang Haoran would never dare to mention Diyuan in this feudal society, because he subconsciously felt that Diyuan would impact the interests of the upper class in feudal society, and he didn't know where this idea came from, and it seemed that it was not mentioned in the textbooks of later generations. The biggest possibility of this idea is that it comes from Copernicus's heliocentric theory, and some people have been burned to death because they support heliocentric theory, so they subconsciously feel that the ancients would not agree with the heliocentric theory. However, that is the story of the West after all, the Tang Dynasty has the culture of the Tang Dynasty, although the rulers also use myths to fool the common people, but those words that fool people are very durable. For example, the so-called gods, Datang's statement is that God is in the sky, it's as simple as that, no matter what shape the earth is, as long as the sky is still there, then the god is still there, and the son of heaven can still exist. However, the heliocentric theory in the West is different, even the Bible that fools the common people directly says that the earth is the center of the universe, and the heliocentric theory impacts the rhetoric of the Bible, and it will naturally be countered by the believers. Those high-level people, if they were replaced by Datang people, how could they make such a cocooned statement? Those illusory things, what is the center of the earth to mention? If you don't mention it directly, this Bible is much more durable, so why worry about being impacted?

is still the high IQ of the Han people, and the illusory things are said in ambiguous words, so in the Tang Dynasty, as long as Wang Haoran does not deny the existence of God, he will not be politically attacked, and at most it is the academic scolding of other scholars, which makes Wang Haoran dare to put forward the theory of Diyuan.

"What? Is the earth spherical? A young man from the Hanlin Academy was frightened by Wang Haoran's theory, and out of respect for Wang Haoran, he thought that Wang Haoran was joking, and said with a smile, "If that's the case, won't all the people below the earth fall into the endless abyss?" ”

Wang Haoran picked up a book casually and lifted it, and as soon as he let go, the book fell to the ground, and then said: "In the understanding of the world, it is normal for this book to fall from the so-called above to the ground and the so-called below, but why does the object have to fall below the so-called bottom? Why didn't it fall into the sky? I don't think the book actually falls from top to bottom, but the earth under our feet has the same attraction as a magnet, and the book is just sucked by the earth. ”

"If so, how does the earth remain suspended in the universe and not fall to other places?" Another young man asked, he knew Wang Haoran this time and didn't joke with them, so he began to think seriously about Wang Haoran's theory.

"This is like the sun, moon and stars in the sky, they do not fall to other places, but move in the sky according to certain rules, and the same is true of the earth where we are, and it is only the same existence as the sun, moon and stars in the vast universe."

"If the earth is attractive, why can't it attract the sun, moon and stars?" An old man asked, he didn't agree with Wang Haoran's theory, but he was not enough to go toe-to-toe with the horse master, and the questions he asked were just facts.

Wang Haoran took a rope, tied one end to the brush, grabbed the other end of the rope and shook the brush, so that the brush circled in the air, and then said: "You see, when this brush is thrown at a high place, why can you still tighten this rope and not fall directly?" The reason for this lies in movement, and so do the sun, moon and stars. Of course, the distance also determines the amount of mutual attraction between objects. ”

"This doctrine can be said to subvert the world's cognition, but if it is just these speculations, it is obviously not enough, I wonder if the young master has other specific matters to prove this?" The young man asked.

"No, if there is, why do I need to discuss it with you here?"

"Then does the young master have a way to prove it? If there is, we can also help the little master. "A young man is still not giving up, he is tired of the days of idle affairs in the Hanlin Academy, if he can let the little young master take a look at it, and then be transferred to the research institute, it will be great.

Wang Haoran thought about it, and there is really a way, that is, to use free fall to prove that the earth is moving, in this case, the statement that the sun, moon and stars move around the earth is not valid, and if it is recalculated, it is easy to get data that proves that the earth is spherical. However, these people from the Hanlin Academy were not experts in astronomy and arithmetic, and no matter how much they wanted to do this research, they didn't have the ability, so they shook their heads and said: "There is a way, but it is very complicated, and if you don't have a certain degree of astronomy and arithmetic attainments, you can't do it at all." ”
