Daming: Old Zhu, we agreed not to rush!

Chapter 95 Su Jing's Training Plan

"Lung step punching, throat piercing kick, horse stance and horizontal strike."

Lishui County, in Su Jing's other courtyard.

Zhu Biao is earnestly playing the first set of military boxing, meticulous and very serious.

Of course, Su Jing is also playing.

After hitting it three times, it stopped.

"Whoo~"

Su Jing let out a breath, then turned to Zhu Biao and said, "Niu Yi, you go to the street to buy breakfast, it's still the same as the third one, I will prepare the tools, and after dinner I will teach you how to make a telescope."

"Yes, Master Su!"

Zhu Biao simply tidied up his clothes, then trotted out the door.

It took a while, and the breakfast was bought.

Fried buns, soy milk and fried dough sticks.

Because Su Jing's other courtyard is facing the street, Zhu Biao is trotting again, so the breakfast is still steaming.

Su Jing washed her hands and started eating.

The hot pan-fried buns are served with pure freshly squeezed soy milk and a deep-fried dough stick, which is delicious.

Food without technology and hard work also has its unique natural flavor.

After breakfast, Su Jing's teaching officially started.

"Niu Yi, if you want to learn how to make your own telescope, you must first understand how the telescope works and why it can see far."

Su Jing looked at Zhu Biao and said slowly.

Zhu Biao nodded and said: "Students understand that Teacher Su has always taught students that when dealing with a matter, you must not only know what it is, but also know why it is."

The longer he studied with Su Jing, the more sensitive Zhu Biao's thinking became.

In other words, it is the modern way of thinking that is changing Zhu Biao.

"very good."

Su Jing continued: "Niu Yi, have you read the Mo Jing?"

Zhu Biao nodded and said, "I have read it, Master Su."

Su Jing asked: "Jing Dao, there is Duan in the afternoon, and Jing Chang. Say Zai Duan. What's behind it?"

As soon as Su Jing finished speaking, Zhu Biao went on to say: "Scenery. People of light, if they shine, those who are below are also high; those who are tall are also down. The feet cover the light, so the scene is above; the head covers the top. Light, so the scenery is formed from below. There is an end in the distance, and it is in the light, so it is also in the scenery storehouse."

Hearing that Zhu Biao answered so quickly, Su Jing also sighed a little.

This child must be really hardworking on weekdays.

In fact, Su Jing hadn't read the "Mo Jing" until yesterday, but it was just to teach Zhu Biao, so he specially prepared the lesson in advance.

But Zhu Biao definitely couldn't prepare in advance, and "Mo Jing" is not a key book that requires special study.

"Now that you know, I won't do the small hole imaging experiment anymore."

Su Jing said lightly: "The core refinement of this paragraph appears, do you know what it means?"

That's right, the description in the "Mojing" is actually the specific description of the phenomenon of small hole imaging by the ancients.

At first Su Jing considered whether to conduct a small experiment, but since Zhu Biao knew everything, there was no need for it.

Although Zhu Biao wondered what Su Jing said had nothing to do with the telescope, he still thought about it carefully.

After a while, he shook his head and said, "Students don't know."

Su Jing was not surprised. Although this aspect is scientific common sense, it is indeed not easy to obtain knowledge for Zhu Biao.

"Then let me ask you again, why do you think we can see things? Besides eyes, what else is needed to see."

Su Jing asked again.

Zhu Biao answered quickly this time: "Light, you can see things during the day, but not at night."

Su Jing nodded and said: "Very good, only when there is light can we see things, and the condition for this small hole to form an image is also light."

"At both ends of the small hole, the object and the image reflected by it are in an inverted state. Does it mean that light travels in a straight line?"

While speaking, Su Jing directly drew a sketch on the paper.

This is the sketch that the teacher gave when he was in school.

The rectilinear propagation of light is inferred from imaging the aperture.

It looks like a small junior high school physics class, which is barely suitable for Zhu Biao's age.

It's just that, after all, Zhu Biao did not receive nine-year compulsory education, and he still lacked some understanding of many things.

Su Jing was also in a hurry, and taught slowly if he didn't understand.

From the straight-line propagation of light to the influence of different media on light relay.

A series of small experiments such as water cup folding and chopsticks, light scattering, etc., Su Jing did for Zhu Biao one by one.

After a whole morning's work, Zhu Biao finally had some understanding of the propagation of light.

Of course, this refers to Su Jing's understanding, if it comes to optics, Su Jing is just an empty bottle.

After all, Su Jing doesn't study physics, and his knowledge in this area is at the level of ordinary high school students.

"Master Su, the student understands."

Zhu Biao showed excitement on his face, which was the joy of gaining new knowledge.

"Niu Yi, isn't it strange? It's supposed to teach you how to make a telescope, but this morning, it's all about the propagation of light."

Su Jing asked with a smile.

Zhu Biao said seriously: "Students believe that Master Su must have deep meaning, students only need to learn carefully."

Although Su Jing often demeaned himself in order to lower his unshakable position in Zhu Biao's mind, it seemed that the effect was not very good.

Zhu Biao still regards Su Jing as a god-like existence.

Su Jing was a little helpless, but she couldn't say anything, so she could only say: "Eat lunch first, and continue after lunch."

Because there was still teaching in the afternoon, Su Jing didn't take Zhu Biao out to eat.

One pot of rice, two home-cooked stir-fries, and one lunch is done.

Su Jing's cooking skills can be taught to the chefs of Jinling Hotel, so Zhu Biao naturally enjoyed his meal.

Seeing Zhu Biao eating happily, Su Jing finally found a little confidence to fail in planting.

God opened a door for me, and it is normal to close a window.

After lunch, after a little digestion, Su Jing started teaching again.

The propagation of light is finished, and the next step is to explain the concave lens and the convex lens.

To put it bluntly, it is actually the refraction of light.

But it is quite difficult for Su Jing to explain this clearly to an ancient person.

Fortunately, Su Jing already has a good concave lens and a convex lens, and it is easier to teach with real objects.

But it took almost three hours, and the sky was already dark, which gave Zhu Biao a more systematic cognition.

"Whoo~"

Su Jing let out a breath, only feeling that this day is very tired.

It is obviously just a self-made teaching of a telescope, but the many common senses of modern physics involved in it are all unknown to Zhu Biao.

Under Su Jing's teaching, Zhu Biao had to find out the root of everything, so Su Jing could only dismantle it bit by bit and explain it slowly.

This made Su Jing deeply realize how difficult the industrial revolution was.

Su Jing once thought about whether he could change the historical course of Ming Dynasty and promote the rapid transformation of feudal society.

In this case, maybe there will be no history of humiliation in the next hundred years.

But now, just teaching Zhu Biao how to make a telescope is already so difficult.

This is still based on the premise that Zhu Biao is very smart, only teaches one person, and does not need to consider social resistance.

It can only be said that the previous self was still a bit too hasty.

"Okay, let's stop here today and continue tomorrow."

Su Jing looked at the sky and stopped teaching.

"Okay, Master Su."

Zhu Biao was a little unsatisfied, but still nodded and said, "Should we still have dinner at home?"

Su Jing shook her head and said, "No, go out and eat."

Don't look at just sitting here teaching Zhu Biao, but it is actually a huge test for Su Jing.

How can I remember so clearly what I learned in my previous life when I came through rebirth.

My student, Zhu Biao, is another kind of "good student". Being a teacher of this kind of student is also very stressful.

The night sky is bright and the sky is full of stars.

The choice of going out to eat is also simple, Jinling Restaurant.

This is the restaurant with the best location in Lishui County, and the box that Su Jing is currently in is also the best box.

Four dishes and one soup are better than lunch, but they are not too extravagant.

"Master Su, is it because the stars themselves emit light that we can see the stars?"

Zhu Biao asked Su Jing.

After learning a piece of knowledge about light transmission, Zhu Biao is still very curious about it.

Su Jing shook his head and said: "Stars don't shine, it's only because the sun shines on the stars, and the light reflected by the stars allows us to see them, and then we can observe the stars."

"Now that there is no sun, how do the stars reflect the sun's light?"

Zhu Biao asked his doubts again.

Su Jing was also a little overwhelmed by Zhu Biao who was so inquisitive, but he still said patiently:
"This will involve astronomical knowledge. After you learn how to make a telescope, you can try to make an astronomical telescope."

"At that time, carefully observe the astronomical phenomena, the changes in the positions of the stars, the moon and the sun, and the answers to these questions will be easily solved."

As a former astronomy enthusiast, this question is naturally difficult for Su Jing.

However, let Zhu Biao ask that he can't answer, why not train him to be an astronomy enthusiast first.

For the mysteries of the vast universe, it would be nice to have one more like-minded explorer.

That is to say, Lao Zhu didn't know what Su Jing was thinking, otherwise he would definitely be furious.

What a future heir of the Ming Empire, you, Su Jing, actually want to train him to be an astronomy enthusiast.

This is simply teaching Zhu Biao not to do his job properly!
"I understand, Master Su, I will study hard."

Zhu Biao said very seriously.

For Zhu Biao, even though the mysteries of the universe are very attractive, Daming is what he cares most about.

Zhu Yuanzhang asked him to learn how to make telescopes so that the frontline soldiers could win the battle.

These Zhu Biao are very clear, which is the biggest reason why he studied so seriously.

From this point of view, Zhu Biao is still a very pragmatic character.

After dinner, Su Jing didn't take Zhu Biao for a walk to digest food. Today's weather is not suitable for wandering outside at night.

Back in the other courtyard, Su Jing took out his astronomical telescope. There are quite a lot of stars today, so it is a good opportunity to observe.

Zhu Biao on the side stood silently, Su Jing didn't speak, so he didn't say anything, and he didn't do anything.

"Huh? Why are you standing here?"

Su Jing looked at it for a while, and just wanted to take a rest, only to find that Zhu Biao was still standing behind her, she said in surprise.

Zhu Biao immediately replied: "Master Su, can the students also look at the stars?"

Even if he is a pragmatist, Zhu Biao is still full of curiosity about the sky.

"There's nothing wrong with that."

Su Jing stepped aside and handed the astronomical telescope to Zhu Biao.

"Thank you, Master Su."

Zhu Biao immediately thanked Su Jing, came to the astronomical telescope, and began to operate it carefully.

The last time he had seen the moon in Donglu Mountain, Zhu Biao was also very curious about the appearance of the stars.

Soon, he saw stars.

But unlike the moon, stars can only be seen as a slightly larger bright spot.

Zhu Biao showed doubts on his face, why was it different from what he imagined.

He turned the direction again and looked at the other stars, all of which were similar with minor differences.

"Why, it's strange, isn't it that you can't see the details on the surface of stars like you can when observing the moon?"

Su Jing said with a smile on the side.

Zhu Biao nodded and said: "Yes, please ask Master Su to clarify."

Su Jing said lightly: "The reason is very simple, that is, the moon is close enough to us, but these stars are too far away."

"The astronomical telescope I made doesn't have enough magnification, so I can see the moon a little bit."

Zhu Biao suddenly realized that in fact, he had already learned some knowledge about magnification in the afternoon, but Zhu Biao was just learning it after all, so he didn't think about it.

"Thank you, Master Su, the student understands."

Zhu Biao nodded and observed again.

Even if he didn't see it so clearly, it was the second observation, and Zhu Biao was still shocked by what he saw.

The vastness of the universe is really fascinating.

Seeing Zhu Biao's expression, Su Jing became more and more satisfied. It seems that his own training plan is really possible!
