I Build an Aircraft Carrier in the Ming Dynasty

The next day, Wu Changqing started work after having breakfast. He didn't have any marriage leave.

As a leader of a force, time is never enough.

In many respects, Wu Changqing has actually devolved his powers. For example, he has hardly intervened in the operation of the administrative system, because he has no time.

But some things must be done by Wu Changqing himself and cannot be replaced, such as writing elementary physics textbooks.

This job is not easy. His memory is not bad, but he doesn't remember what the physics book in junior high school looks like. He can only write down all the knowledge points he knows.

He has been doing this for the past few days. He has written elementary physics for printing. Now he is writing elementary geography, and he has left chemistry at the end.

"Xianggong, what article are you writing, why can't I understand it. Isn't our world a round place? How can it be a round sphere?"

Chen Yuyan came over to deliver tea and saw what Wu Changqing wrote. However, she knew all the words above, but she couldn't read them together.

Wu Changqing smiled and explained: "If you have been to the seaside and watched the sailboat go out to sea, you will find that the first thing to disappear is the hull, and the last thing to disappear is the mast. When the sailboat returns, it is the first thing you see. The mast, and then slowly see the hull. This is only possible on a spherical arc."

As Wu Changqing spoke, he also spent a simple arc.

With pictures to annotate, it is much easier to understand.

Chen Yuyan was stunned when she heard the words. She had never been to the seaside, but she had seen the sailboats in Taihu Lake. Looking back carefully, it seems that this is the case.

However, she still could not accept that the world is a ball.

"However, it is also possible that the sea is actually a convex arc, but the earth is still flat. If our world is a sphere, wouldn't the person standing below fall?"

Chen Yuyan also drew a line, with straight lines at both ends and a bulge in the middle.

I'll go, I'm married to a scholar?

Wu Changqing was surprised to find that his wife's reaction was so fast that she could think of a reason to refute so quickly. Although this reason was full of loopholes, it was quite good.

"People go to high places, water flows to low places. If the sea is raised, then the water will flow from the sea to the river, not the river to the sea. As for why you said that the person standing under the ball will not fall, This explanation is complicated, and I will tell you later when I have time."

The concept of universal gravitation is still quite abstract, and it is very difficult for people in this era to suddenly understand and accept it.

Although Wu Changqing really wanted to show off in front of the lady, time did not allow it.

Chen Yuyan closed her mouth when she heard the words, she knew that her husband was doing a big job now, and she couldn't disturb her.

Although she still has many questions about Wu Changqing's theory, the female training told her that she must trust her husband unconditionally.

Our world is round, how can it be round? How can the person under the ball not fall? But if it's not round, how can you explain the phenomenon of sailboats?

Chen Yuyan left with doubts, and couldn't help but mutter, almost scaring Zi He. She also thought that her young lady was a victim of evil.

The next day, on the day of the university admissions, Wu Changqing came to the university together with several great scholars who taught classics, strategy theory and arithmetic.

Several great Confucians headed by Shen Lianming were somewhat disdainful of Wu Changqing's desire to set up a subject of physical geography and to impart knowledge in person. But because of Wu Changqing's identity, they dared not show it.

Even, in order to get the teacher's job, they had to please Wu Changqing. In troubled times, it is not easy for these great Confucians who only memorize articles.

Those who are in demand now are those who can lead troops to fight, and the status of civil servants has dropped again and again.

In the university hall, there were already more than 200 scholars, aged between fourteen and thirty.

When Wu Changqing and Shen Lianming appeared in front of these scholars, everyone's eyes were on Wu Changqing. Most of them saw Wu Changqing for the first time.

Looking at this general who is younger than himself, but holds a heavy army and controls the fate of countless people, everyone's mind is different.

Some are envious, some are jealous, some are admiring, some are dismissive.

Wu Changqing didn't know the thoughts of these people, so he gave a speech as usual.

"Everyone is a scholar. I don't need to say more about the saying that knowledge changes destiny. What I want to say today is that knowledge can not only change the destiny of an individual, but also the destiny of the country and the world.

For example, without knowledge, such advanced weapons cannot be made, and battles cannot be won..."

Wu Changqing asked the personal soldiers to hand over a flintlock gun, and then demonstrated the operation in public.

This advanced weapon opened their eyes.

Then Wu Changqing continued: "Which of you can create a weapon more advanced than this flintlock gun, I can directly worship him as the chief staff member, or directly call him a military division, and choose any official position below the second rank, and there will be no shortage of titles. ."

Desire is always the biggest driving force of human beings. Wu Changqing didn't talk about too many big truths.

Scholars take the normal way to study for the imperial examination, even if they are to be the champion, they have to start from the sixth-rank official, and the second-class jinshi can only start from the seventh-rank magistrate.

It is even more difficult for those below the second grade, and sometimes it is not necessary to wait for more than ten years to get a real job.

These scholars are very aware of the difficulty of taking the second-class test, which is really one in ten thousand.

But now, Wu Changqing directly called out the official positions below the second rank and picked them at will.

Nima, this kind of temptation is definitely bigger for these scholars than Qin Huai Bayan standing naked in front of them.

The eyes of all the scholars were scorching hot, and they were so excited that they could not wait to study the manufacturing method of fire guns now.

Of course, there are also a few more sober readers who are very depressed. It's no problem to let them take the imperial examinations, but to research and manufacture new firearms, that's not his area of ​​expertise.

"How to make this flintlock gun? You may still be confused. But don't panic, I will teach you the secrets in the next class.

After learning the physics knowledge I taught, it doesn't matter if you still can't build this kind of weapon, people who have mastered this knowledge will be very useful to me. What I can guarantee is that as long as you pass my assessment, your official position and military power are waiting for you.

If I don't study these knowledge with heart, I will expel those who fail to pass the examination without mercy. "

Wu Changqing's assurance once again made those readers feel that he attached great importance to this knowledge.

Some people who originally looked down on physical and chemical geography have changed their concepts a lot at this time, and have silently made up their minds to learn that knowledge.

As for whether that knowledge is as useful as Wu Changqing said, it doesn't really matter at all, everyone is just looking for a chance to become an official.

Just like the classics used in the imperial examinations, it is still not used very much after becoming an official, but everyone is not desperate to study, isn't it just to pass the assessment and get a chance to become an official?

After Wu Changqing finished speaking, he also asked Shen Lianming and other great scholars to say a few words. Their speeches are more traditional, and they are nothing more than asking everyone to cherish this opportunity to study and study hard.
