Geng Youhua listened to them argue several times, but he never understood the point, what kind of circle they were talking about, what kind of square or something he didn't understand at all.

Immediately, the shameless character of the literati came up, got up and walked to the table next to him, and said to these young people who were also dressed as scholars: "Geng Youhua in Xia Sanshui, disturb your brother Tai Yaxing!" ”

Those few people looked back at Geng Youhua, and saw that Geng Youhua was also dressed as a scholar in Confucian clothes, and immediately gave his hand politely, one of them seemed to have heard of Geng Youhua's name, and immediately got up and said: "Dare to ask Brother Geng, but Geng Youhua of Qingsong Academy is the thirty-sixth year of Sanshui County?" ”

When Geng Youhua heard this, there were still people who recognized him, and he ranked second in the county examination that year, which was also a small achievement in his imperial examination, and he immediately felt a little more comfortable, but he did not show any pride on his face, but said with a humble look: "The small county examination list is not enough to worry about?" I don't know what year Brother Tai went to school? ”

After hearing this, the young man immediately said, and immediately said: "Back to the seniors, the younger generation is Deqing Cai Minghang, who just entered the school this year!" ”

New to school this year? You don't need to ask Geng Youhua to know that the person in front of him must be a pseudo-Tang imperial examination that he participated in, and he is a talent in the examination.

If it was this time last year, he would have directly scolded this person for being a thief, but now, the situation in the world is different, not to mention these juniors, even if it is his classmates and friends, or even those seniors who lift people, they are all thinking about participating in the pseudo-Tang imperial examination, this world is no longer the same.

However, although he was not ready to talk to the people in front of him, he still maintained a friendly atmosphere and changed the topic by the way: "Oh, just now you said that there was a big round ball under our feet?" ”

Hearing Geng Youhua say this, those few people just started talking about it again!

"Isn't it, this newspaper says that the earth under our feet is not flat, but round, and it is a huge ball, which can be walked all the way in one direction, and we can walk back to the original point!"

"It's a fallacy, if it's a ball, why don't the people on the other side of the ball fall?"

Hearing that they were arguing again, and Geng Youhua also heard them say that they had seen it from the newspaper, and they also had a newspaper on their table, so they immediately opened the newspaper in their hands.

He quickly flipped through the pages he had already read, and finally came to the penultimate page, where he finally saw the ball they were discussing.

This is a small column in the newspaper, called 'popular science', and a small line of introduction: popular science astronomy and geography, heaven and earth.

That's a big breath!

Looking directly at the text below, this article is the same as the discussion of the people just now, saying that the place where people live is not square, but a super big ball.

And it is explained in detail why the earth is round!

First of all, they cite the deeds of foreigners who sailed to the earth, and use practical examples to prove that the earth is round, and secondly, the curvature of the sea level.

Then he also explained why it didn't fall, because our earth has a gravitational pull from the center of the earth, which firmly binds people on the surface, and explains it with gravitational pull.

Finally, if you are interested or in doubt, you can refer to the book 'Intermediate Physics' written and published by the Royal Academy of Sciences.

Intermediate Physics? He hadn't heard of the title before, but he had heard the word physics many times!

Because in the imperial examination of the pseudo-Tang Dynasty, not only the eight articles were examined, even the scholars of the Jinshi Department had to learn and take the erudition, which included arithmetic, physics, chemistry, astronomy and geography, etc.

It's just that the scores of these test questions don't occupy much weight in Jinshi, but he knows that the entities tested in the doctoral department are all based on these subjects, and the Bagu article is just a reference.

Although this situation has aroused the opposition of a large number of scholars, China has this advantage: some people want to be officials!

If you resist, don't study, and shouldn't take the exam, there will naturally be other scholars who will study, and then pass the exam and become an official.

Therefore, after the opposition was invalid, those students who were interested in participating in the Tang imperial examination had to start learning these subjects that they thought were miscellaneous studies, but fortunately, in the imperial examination of the Tang Dynasty, the students who applied for the Jinshi examination did not need to master how deep they were in this knowledge, as long as they memorized the superficial knowledge they had mastered, it was enough for them to cope with the imperial examination below the township examination.

Even Geng Youhua, a student who was still waiting, actually secretly bought several books published by the Royal Academy of Sciences, and even asked someone to hand-copy a few textbooks from Guozijian, and also did some exam questions of Guozijian Literature College.

So Geng Youhua still has a basic understanding of this physics, and now the intermediate physics mentioned in the morning newspaper is probably to buy it and take a look, not that Geng Youhua is interested in where the earth is round, in fact, these things don't care about him, whether it's round or square, he is not alive and well.

The reason why he wanted to buy it was to see 'Intermediate Physics', naturally to prepare for the imperial examination in the future.

He is a scholar, and participating in the imperial examination as an official is the meaning of his whole life, if the official army has been unable to exterminate the puppet Tang Dynasty and recover the land of the three provinces, then he has to participate in the puppet Tang imperial examination like those classmates who are one step ahead.

He must participate in the imperial examination, whether the imperial examination is run by the pseudo-Tang Dynasty or the Ming Dynasty, in fact, there is no essential difference for him, the only thing to encourage is the risk.

So after reading the newspaper, Geng Youhua got up directly, and then prepared to go to the bookstore opened by the Royal Academy of Sciences to buy books.

As far as he knows, most of the books published and printed by the Royal Academy of Sciences are related to the imperial examination, and most of the books published in the early days are related to science, and later they also published books closely related to their Jinshi department, especially the collection of examination papers of those Jinshi subjects, which are widely welcomed by scholars.

If we look at it from the perspective of later generations, in fact, the books published by the Royal Academy of Sciences are all teaching books, and the scholars bought them to read, not because they liked it, but because these books were directly related to the success or failure of their imperial examinations.

Even if it is a scholar from a less privileged family, they will find a few friends to buy it together, and then copy the books from each other, and then collect a complete set of manuscripts by themselves.

With these books, they can learn the content of those liberal arts on their own, and they can also better understand the requirements of the imperial examination for some historical theories and policy theories.

This point is actually no different from the students of later generations, China's education for thousands of years, from beginning to end is exam-oriented education, the biggest motivation for students to learn is to cope with the exam, so as to reach the peak of life.

And what they learn, in fact, they don't care much!

Soon, he arrived at the bookstore under the Royal Academy of Sciences, and sure enough, as soon as he entered, he saw rows of 'intermediate physics' in the most conspicuous position, no need to look, no need to think, he just picked up a copy.

By the way, I also purchased the new 'Intermediate Chemistry', 'Intermediate Arithmetic', 'Intermediate Astronomy and Geography', and 'Geometry'.

He found that these books were just on the market yesterday, and there were many people who bought them, and many people, like him, came directly to these new books.

He even found several seniors to buy it!

By the time he took these books to pay the bill, the new books on the shelves were already half missing, and by the time he took the books and left, the new books on the shelves had already been looted, and many scholars were shouting for the men to move the new books out of the stock quickly.

The situation in the bookstore, he Geng Youhua doesn't care, anyway, the book is already in his hands!

On the way back, he also briefly read the book of intermediate physics, and found that the content in it was too profound, and quite a lot of things were unbelievable, he also saw the article on gravity, and then according to the formula mentioned above, when he tried to calculate it, he found that his arithmetic skills were not up to par, and in the end he had no choice but to give up.

However, it has been planned that these new books must be studied carefully, and if I also participate in the imperial examination this time, I am afraid that these books will be able to come in handy.

His guess was not wrong, Li Xuan instructed the Royal Academy of Sciences to compile and publish this series of intermediate science books based on the textbooks of the young military camp, which was to prepare to increase the weight of science content in this year's township examination and next year's general examination, and at the same time deepen the difficulty.

In the past, students who entered the Shike only needed to calculate the simple addition, subtraction, multiplication and division to be able to pass the test, which is impossible in the future.

And the polymath will be even more profound!

Otherwise, what did he ask the Royal Academy of Sciences to publish these books, these books were all written by Li Xuan himself in the past and used as teaching materials for the young military camp.

Later, it slowly evolved into the teaching materials of Guozijian and young students from all over the country, and now, he wants to make these teaching materials become teaching materials for ordinary students.

But there are textbooks, but there are not many teachers, except for the Guozijian, the young military camp, and the juvenile college, the other students can only rely on self-study.

There is no way to do this, as long as the books are printed, you can have as many as you want, but there are not many teachers, especially those who can teach advanced courses.

Nowadays, the biggest source of teachers is the young military camp, but there are not many senior students in the young military camp, and the students who can become senior students are all top students, and they will spend a lot of time to learn more new content on their own, and then conduct experiments, do some research, and become teachers? It's a waste of time for them.

The reform of education is also the highlight of Li Xuan's preparation in the second half of this year, and he is going to start promoting modern education on a large scale!
