For the name of Princess Jinmai, these noble daughters of the Wang family were still a little jealous, so they didn't answer and went back silently.

Because their dignity is not as high as that of Princess Jinmai, although they are the royal bloodline.

However, in terms of practical effects, and Princess Jinmai has brought a lot of money to the royal family in recent years, they can't compare.

In front of the emperor, even their father has no way to compare to Princess Jinmai.

What's more, they are just the daughters of their father, and they have almost no contribution to the royal family.

In the family, in politics, there is never a way to achieve an important position.

Unless she can enter the palace and become a concubine or a crown princess or an empress.

But now the positions of the queen and the crown princess seem to have no possibility of changing.

And as the nieces of the Liu family, it is even more impossible for them to marry the emperor or the crown prince.

The taboo of not marrying with the same surname existed in the Han Dynasty, and in most cases, they still abide by it.

It's just that if they don't have the same surname, even if they are close in blood, they still like to kiss each other.

Therefore, most people still have no way to understand the true meaning of not marrying with the same surname.

For the Chang'an Women's School, it has been publicized that she is going to talk about motors, Qian Rujun is a little helpless, this is the first cut and then the prelude!

Because she did not accept the head of the school, she agreed to teach in the school.

And the head of the school actually did it, for the reputation of the head of the school, and for the credibility of the Chang'an Women's School, she had to carry it out.

Everyone, and only she cares about this.

For the sake of the reputation of the women's school, it is impossible for her to refuse.

She had a feeling of being pitted.

To be honest, she wasn't impressed with the motor because she was a liberal arts student, not a science student.

She didn't know much about mechanical things.

At this time, it is best to call these people who know motors from Qinhuangdao.

It's a pity that I didn't have time to catch up with the start of the class.

The only way to do this is to take out the basic book of motors and read them, and cramming them for a while.

In Qian Rujun's impression, the motor is a machine that rotates constantly.

The power for its rotation may come from electricity, water conservancy or firepower.

In the case of electricity, the magnetic force is triggered by electricity, and then the positive and negative electrodes are repelled to produce rotation.

In terms of hydraulics, it is to use water power to generate kinetic energy to propulsion.

In terms of firepower, it is the use of fire to boil water, which produces steam to propulse, and promotes the rotation of the blades.

Of course, in later generations, due to the development of electricity, it is possible to generate electricity through this way not only water or fire.

To talk about something that he didn't understand at all, Qian Rujun also had to enter the space and ask the school that understood the motor.

Let the students of Xuetang Island come and teach her lessons.

Because she relied on herself to read books, in fact, it may be like a mountain, and she found it very difficult to understand by reading books on her own.

It's better to find someone who understands to do the simplest explanation.

After all, if she wants to tell others, she basically only has the key points, and it is impossible to really go into detail.

But after knowing the principle and principle, in fact, the smart Han people will naturally come up with the big truth.

The physical object is manufactured, and perhaps the physical object that was manufactured at the beginning is not as good as Qian Rujun.

But they have seen what Qinhuangdao has made, and they will definitely improve it.

Later, it is estimated that it will be able to catch up slowly.

In this era, there are no intellectual property rights, and they are even able to imitate them. Walk in the footsteps of those who came before you.

Later, there are intellectual property rights, but there are also certain shortcomings.

That is, once they apply for the concept or physical object of intellectual property rights, they cannot use it.

Unless you're willing to pay.

So there is no way to imitate, you can only rely on your own ideas to find a way, bypassing the methods used by predecessors, in fact, this is also a waste of time and energy.

The next day, when she was in class, she saw several familiar figures.

But because her identity is Princess Jinmai, the appearance and appearance of the girl they know are actually completely different.

Princess Jinmai came to the stage to give a speech, of course, she would not be disguised, but several girls said that the girls they knew were disguised.

I don't know if they will notice that the person they know is Princess Jinmai.

Relying on special power to change the face is probably too unimaginable for ordinary people!

For the Han people, Qian Rujun's teaching is a unique teaching and speech.

What Qian Rujun said, they can actually understand, but the deeper they go, the more blurred their brains become, just like Qian Rujun himself can never figure out the deepest things.

After going beyond what the students of Gakudo Island told her, she discovered a fact.

The students of Gakudo Island don't really understand such a thing as motors.

In the end, the generation of the motor is no longer the wisdom of one person, but the wisdom of many people.

One person may not be able to understand everything, but everyone can understand different things, and together they become a great force that moves the world forward.

Qian Rujun hadn't thought deeply about motors before, but during this speech, she found that she had a further understanding of motors after teaching.

This simple rotation is the driving force for the rapid progress of future generations.

Qian Rujun looked at the eyes of the people who were listening, their eyes were shining, maybe what they got was also a part of the essence of her speech.

Perhaps they could think further away in the future than she did.

The spark of wisdom they will create may be different from the spark of wisdom that she will bring from the afterlife, and open up a new path.

Maybe she is vague, and there is a benefit to ambiguity, because it is not clear enough, so people will add their own thinking, and if it is clear enough, people can only understand it in the clearest place, and it will reduce the creation.

During the Han Dynasty, even with the addition of Qian Rujun, the progress of steel manufacturing was not great.

In this period, the kitchen utensils and knives were actually still very soft, and perhaps the building technology of the Han Shaofu was very high.

But most of the craftsmen themselves are not engaged in creating, they are just accustomed to making things according to the better practices handed down from their predecessors.

But Qian Rujun didn't really get the building technology of Dahan.

The strongest iron weapon is in Shaofu, which is used for military purposes.

After all, the iron tools outside cannot be compared with those used for military purposes.

It is not a problem for Qian Rujun to make some iron tools that can produce functions as long as the shape is changed, but if you want to make hard iron tools, it is a big problem.

Hard iron can not only be used as a weapon, but can also play a greater role in due time.

For example, iron can also be used in train carriages, but in fact, alloys are more useful than iron.

Perhaps the Han craftsmen should have embarked on the study of new alloys, rather than be satisfied with the existence of bronzes.

According to Qian Rujun's knowledge, alloys can make iron produce different characteristics, and with different characteristics, it can adapt to different needs.

There is also some iron, which needs to be hard, some iron that needs to be soft, and some iron that needs to be sharp, just like people have different personalities and are suitable for different positions.

If Qian Rujun himself was in an obedient position, it is estimated that there would be no current Qian Rujun.

She is not suitable to be a leader, but in Dahan, she has a more advanced vision, and she is more suitable to be a guide.

"Do you understand what the princess said? I think I'm so vague!"

The tone of the questioning student was frustrated.

"I understand part of it, but I won't tell you, this is top secret, I guess the princess won't talk about it a second time, I have to go home and record it quickly, think about it, I don't have time to talk to you here, goodbye." ”

"How can you just leave like this, are we still good friends?"

"When I encounter the interests of the family, it is useless to be a good friend! I must let myself contribute to the family first, gain status in the family, and let the family have a good development, so that I can help you!

After I can get the benefits, I will share a little of the benefits with you. But if I don't grasp the most basic things, I can't create more benefits to share with my friends.

So the most important thing for me now is to write down what I remember in my brain as soon as possible, my brain is not very good, and it will be over if I write it down quickly. ”

After speaking, the female student left in a hurry, although she thought she was not smart enough, but compared with other students of the Chang'an Women's Academy, the people who would be sent to the Chang'an Women's Academy to develop were basically the elites of the family.

Although not all of them are high-achieving students with an IQ of 180, they will not be stupid.

For the first time I came into contact with something, it is still very troublesome for many people.

So they have to go back and get their stuff and write down what they remember.

Those who will stay on the road and ask others how the situation is, it is estimated that they are all people who have nothing to gain from what Qian Rujun said.

This kind of person is not necessarily stupid, but his head is more inclined to liberal arts, and he is more good at poetry and songs, but he has no concept of the real objects they looked down on in the past.

They don't have a science or engineering mind.

A person's head is rarely omniscient and omnipotent, and if it is omniscient, her future development may not be the best.

Because she will be very confused, she doesn't know where she should focus on, only by focusing on one place, can she sprint with all her strength and surpass everything.

"I don't even understand it, but this knowledge is really profound. ”

The head of the Chang'an Women's Academy stood next to Qian Rujun, looked at the scattered academy students, and said with a sigh.

She doesn't think that students are going to learn worse than she is, because what they lack is experience and knowledge, but young people's brains tend to be more flexible than older people's.

The head of the school thinks that she is old, and in this era, there are many people who feel that they are old people in their thirties and forties.

Because it is not easy to live to the age of seventy.

In their eyes, it is estimated that it is difficult to imagine that Qian Rujun lived in that era, and often felt that life only began in his seventies, because seventy-year-old people are often very healthy and can travel everywhere.

From the moment he decided to spread the knowledge of motors, Qian Rujun knew that this was a world-changing initiative.

The beginning of the so-called industrial revolution was actually the steam engine, and why can the steam engine drive the development of the world?

In fact, what the steam engine drives is rotation, and when the rotation is final, it will become a motor, so Qian Rujun directly skipped this part and pushed their time forward by a hundred years.

She didn't teach the students of the Chang'an Women's School, what about the steam engine.

But in the Chang'an Women's School, many buildings use steam engines.

He didn't start with the steam engine and explain it slowly, but directly explained the role of the motor and the principle of rotation, and he didn't say much else.

Because even she doesn't know very well.

She thinks that even if she taught them, if they were to know the principles before they had deep thoughts and were immersed in the study of inventions, it would actually be confusing for the people of this era.

It's better to give them a part of the basic principles and let them think and think.

When their brains have matured, if they have not developed to what Qian Rujun knows, then Qian Rujun will tell them further knowledge.

They will be able to understand better, and Qian Rujun will also be able to study further knowledge during this time.

This knowledge cannot be obtained in a short period of time.

She knows that she is very smart, and she has experienced various advanced times of motors, so she still has a basic understanding of such things as motors.

Therefore, the effect of her research is estimated to be more effective than that of the students of Chang'an Women's School.

It's just that her liberal arts head may be studying profound things, and she will have some incomprehension, and she can only understand superficial matters.

However, compared to the poor and ignorant men of the Han Dynasty, it is estimated that they will encounter a greater impact.

It's a pity that these female academy students, in the future, their families, will not give them time to continue research, and it is estimated that they will still be handed over to their subordinates to do research.

And those subordinates, presumably men.

Qian Rujun thinks that as long as she knows the superficial matters and tells others that she can do this, others will slowly find a way to study this matter.

Unless they think that this thing is the power of the gods, and they don't believe what Qian Rujun said, but when the motor is really presented in front of everyone, even if it is relatively basic, they will change this thing from the power of the gods to the power of human beings, and enter to further expand their world.

"I don't understand myself, I don't know how much they understand, if they can only understand what I understand, then the reality is too bad, I hope they can develop their imagination from these words. Because I don't understand things, in fact, they are the essence, but I can't understand them yet. I can only hope that some of them will understand!"

"If it was at the beginning of the school year, I probably didn't have such confidence, but after more than a year of study, I now have more confidence in them, because after more than a year of study, I can find that these students' brains are not stupid.

The students in the women's school are very smart, and I can't understand math, and almost every one of them can learn, maybe it has something to do with their family doing business!"
