Chapter 235: Difficult teaching

In a vacant school in Bowen College, Luo Xin and Yue Yun took all of their people to take their seats.
Xiao Ming was standing on the podium at this time. He looked at the people below and thought that he might have the same life as the teacher in the future.
For him, it is his advantage to spread scientific knowledge as much as possible now.
"This academy will be the academy of the Naval Academy from now on. If you inform you to take classes in the future, you will gather here." Xiao Ming said to Yue Yun and the others.
"Yes, Your Highness." Yue Yun and the others looked excited, and their answers were particularly loud. How could they, the children of fishermen who were fishing on the sea, ever think that they were qualified to take classes in a school?
When they were young, they envied those who were able to study in private schools, because once they were able to study, it meant that they would hope to be a high official in the future, but not being able to study meant that their fate would only be the same as that of their ancestors and generations. Is a fisherman.
"Navy Academy? Your Highness, shouldn't our artillery also have an artillery academy?" Luo Xin roared.
Xiao Ming smiled and said: "Of course, the vacant room next door is the artillery academy's academy. After the king gives you the artillery aiming method, you will be responsible for giving lectures to the artillery."
"Really." Luo Xin laughed.
This Bowen Academy is a very mysterious place to outsiders, because as an academy, it is guarded by guards and it is as tightly guarded as a barracks.
And unlike a small house in a private school, Bowen College has a large area, and there are many vacant classrooms in the college, and some of them are under construction. When they passed by a school just now, they saw Lu Tong speaking in a school. He was surprised by some weird knowledge and a group of scholars sitting below.
Xiao Ming nodded. For convenience, Xiao Ming plans to build Bowen College into a comprehensive academy. This is also for the convenience of class, otherwise it would be enough for him to just run back and forth.
And even though many scholars were admitted to the Bowen Academy, based on the base of Qingzhou scholars, this number is not more than a thousand.
In addition, technical personnel such as Lu Tong, the Department of Equipment, Mines, and Military Workshops, as well as the Navy and Army in the future, will only have more than two thousand people. In modern times, it is basically the size of a middle school.
Therefore, now basically a person with only one school major.
After designating this school as the Naval Academy’s school, Xiao Ming said: "Yue Yun, you said sailing is very simple, so this king asks you, how do you sail on the sea?"
"Of course it's walking along the place where you can see the land?" Yue Yun looked like he took it for granted, his expression was a little smug, and he felt that Xiao Ming had something he didn't understand.
Xiao Ming sneered.
This school is a brick-concrete structure, that is, a modern tiled house. He specially asked to leave a blackboard in front of the school.
Basically, this school is not much different from modern teachers. At the beginning, the craftsmen didn't understand what a blackboard is. Xiao Ming also came here to instruct the craftsmen.
The blackboard in the school is actually very simple. It is just a smooth cement board, and just paint the cement board with black paint.
At this time, in front of Xiao Ming, he had chalk. The chalk materials were limestone and plaster.
In order to facilitate teaching in the classroom, he deliberately used limestone and gypsum to make modern chalk. After all, this is not a complicated process. The cement is produced by the way.
Picking up the chalk, Xiao Ming drew a large oval on the blackboard of the school, and then outlined it with a pen. Twenty minutes later, an accurate world map appeared in front of everyone.
"His Royal Highness, what is this? A map? A map of what place?" Luo Xin saw that this was a map, but couldn't tell where it was.
"This is a map of the world. This whole is called the earth. Now we are living on the earth. Let me ask one more question. Do you think that the sky is right?"
Luo Xin grew up in a Confucian academic atmosphere. He said: "His Royal Highness, you are a joke. According to Confucian records, in "The Great Dai Li. Zeng Zi Tian Yuan", the single Ju Li asked Zeng Zi: Tian Yuan As for the place, it is true that Zeng Zi said: The sky is round and the place is not covered by the four corners. It can be seen that the sky is a round place.
At this time, Yue Yun was silent. He had not received Confucian education. The people in the fishing village were illiterate and no one talked about it. He suddenly said: "His Royal Highness, Cao Min doesn't know what Jingshi Ziji, but every time he sees a fishing boat coming back At times, we always see the sails first, and then the hull. If the ground is square, how could this be?"
Xiao Ming smiled and nodded, Luo Xin's thoughts were deeply ingrained, and Yue Yun would be suspicious because he didn't study.
"The reason you see such a scene is because the place where we live is round." Xiao Ming concluded.
Luo Xin burst into laughter when he heard this, as if he heard a big joke, "His Royal Highness, I believe you all else. This is something that is rude to Luoxin and passed down from the ancestors. Your Highness can't just talk nonsense."
When he uttered this theory, Xiao Ming knew that he would encounter a lot of resistance. Changing the thinking of an era was much more difficult than establishing an industrial system.
Therefore, he never thought of expanding the popularization of this kind of knowledge, just spread the advanced knowledge in the Bowen Academy first.
However, looking at Luo Xin's appearance, he basically understood what happened to him. Luo Xin was only a military attaché. If he told those pedantic scholars, wouldn't they want to fry the pot directly?
With a secret sigh in his heart, Xiao Ming said that this popularization of scientific knowledge has a long way to go. He must be patient and also withstand the pressure.
He said: "Luo Xin, you know a lot, then I ask you, why after you clearly aimed at a target with a cannon and fired, the impact of the cannonball always differs a little."
Speaking of this question~EbookFREE.me~ Luo Xin hesitated and said: "His Royal Highness, this is the same as a bow and arrow. The bow and arrow shot will always fall, and the shells are the same. Train more and practice makes perfect."
"You know it and don't know why." Xiao Ming said with a smile.
Luo Xin scratched his head, wondering: "What else is there?"
Although Luo Xin had also studied hard in the cold window, in the eyes of Xiao Ming, he had only studied Chinese for ten years, so it is normal for the descendants of the ancients to write articles.
However, Luo Xin is no different than an idiot in these things.
The aiming of this artillery of course also has the principle of parabola. The current artillery basically uses the principle of aiming at three points and one line, and every artillery has front sight and rear sight.
But these front sights were just for emergency at the time, and the aim was not accurate. The reason why he called Luo Xin to come here was to teach him to calculate the parabola and adjust the front sight, so that in the future the front sight will aim at the point where the sight is calculated by the parabola, so you can hit it directly.
