Throughout the ages, homework has always motivated people.

After Ji Mo went back, he wanted to do his homework overnight, but Nai He Gao looked at his body, couldn't hold on, and went back to sleep. He didn't get up until the sun was high the next day, and sat at the desk to study his calculation homework.

Ji Changwei took time to come over a few times, passed by the window, and didn't go inside to watch, but the shadow swayed back and forth, and Ji Mo always saw it. ...

"But what's the problem?"

Ji Changwei asked directly.

"No."

Ji Mo answered frankly. For him, the hard part is that there is no correct answer. Generally speaking, it is a bit mysterious. God knows whether the final result he gave is correct or wrong. Feeling a little foggy.

Like some kind of language.

However, if it's just a calculation, it still won't bother him.

Since elementary school, after studying for these years, it is a joke to dare not calculate.

Ji Mo still has this bit of self-confidence, so his voice is sonorous, and he doesn't lack confidence.

Ji Changwei seemed to be somewhat disappointed, he didn't say anything, but he didn't leave either, and turned back after a while, the shadow fell on the table, Ji Mo looked up, as if he was looking at the person who was always lingering by his side Like the invigilator, you can't go to other places?

It doesn't affect thinking.

"But what's the problem?"

Ji Changwei asked again.

"No."

Ji Mo's answer was the same as before, Ji Changwei kept a straight face, and said patiently: "If you have any difficulties, just say it, it's the first time you've seen this kind of scene, there must be a lot of things you don't understand, if so, just tell me directly. Ask, and I will explain it to you."

Ji Mo, who was about to say "no" again, heard this, thought about it, oh, this is waiting for him to ask him for an answer.

Ji Changwei, the father, has always had no authority in front of Ji Mo. His fear of heights is well-known in the Ji family. Although Ji Huan will not deliberately publicize and despise Ji Changwei to the younger generation, he will not deliberately cover it up, talking about it It is inevitable that there will be some disdainful meanings revealed.

In addition, Ji Huan directly took over Ji Mo by his side, which is a good thing for Ji Changwei. His son may have a higher upper limit than himself and develop better, but it is also a bad thing. As a father, he has no sense of presence in front of his son!

So, the other party came to brush up the sense of presence.

Ji Mo didn't understand this meaning, but he also felt that Ji Changwei wanted to ask something by himself, but for the time being, he really had no doubts.

"Daddy, wait, wait until I finish writing this, and ask Daddy to correct me!"

Saying this, Ji Mo motioned for Ji Changwei to sit down beside him. The invigilator who was sitting was a good teacher. He was always walking around and turning around, but it was not very good.

"Okay, you calculate it first, and then hand it over to me."

Ji Changwei responded readily, even a little bit happily, and sat down on the side seat, not in a hurry to come over to see how Ji Mo did the calculation, just like a supervisor, just waiting on the side.

Ji Mo’s calculation results will be released soon, and the direction is somewhat different. After watching a meteor shower, if you write related impressions, you can also have several directions. What is the instability of the sky, what is the chaos in the world, what is the chaos of war... …These are the predictions of the direction, and there are some specific questions about whether the distance of the stars is related to this meteor shower.

Ji Huan didn't say which direction it was, but asked Ji Mo to try to write and see his level. Ji Mo chose a direction that he was most sure of, and summed up the scale of meteor showers in the world over the years. The similarities and differences of this meteor shower, and at the same time vertically compare the possible impact of this event.

In this regard, the proportion of data should account for two-thirds. Putting the data and reasoning, the latter is the conclusion of one's own argumentation. Relatively speaking, the difficulty of calculation is greatly reduced.

Ji Mo didn't know if his writing was correct, the specific format, or if there was any problem. From the corner of his eye, he looked at Ji Changwei who was focusing on him. Fortunately, the other party came to help him. He really needed to do it before handing in his homework. Let the parents check it out.

After a quarter of an hour, the article was completed, and Ji Mo handed it to Ji Changwei, waiting for the other party to finish reading and make comments.

"you--"

Looking at Ji Mo's article, Ji Changwei didn't know how to say something. If it was useless, it wouldn't be true, but such a result whose summary nature is greater than the proportion of calculation is probably not what Ji Huan wanted.

Thinking this way in his heart, he was about to give some pointers when he saw Ji Huan walking into the courtyard, saw both of them were here, Ji Changwei was still holding the manuscript in his hand, and said, "It's finished, show me."

While speaking, the hand has already stretched out.

Ji Changwei hesitated, but still handed over the manuscript and handed it to Ji Huan.

Ji Huan's expression has always been rather cold and hard. Now that he read the manuscript, there was a slight change. Looking at Ji Mo again, he commented: "It's not bad."

It was actually letting him pass the test like this.

Ji Changwei's eyes were amazed, Ji Mo didn't know the root cause, so he breathed a sigh of relief, as long as he can make a difference, he must pay attention to it in the future, read more articles like this of others, see how they did it, and then do it himself, not to mention copying, At least there is a template.

Ji Huan walked into the room with the manuscript, and talked to the two about the stargazing mirror, "It's supposed to be a while, but I've already got it today, and I just sent someone to distribute it for observation. It is close, but there is also a disadvantage, the angle of view is too narrow, and the whole picture is not obtained. I intend to erect a dome on the stargazing tower, and create it with the principle of a stargazing mirror. "

"This is a good thing!"

Ji Changwei responded positively.

Looking at Ji Mo again, he opened his mouth slightly, a little surprised, this kind of thinking, is it because the eyepiece of the stargazing mirror is too small?

Directly using a roof as an eyepiece, this kind of idea, this kind of creativity... It seems, it seems to be really possible!

After making some calculations in my heart, I have already responded first: "Grandpa has a very good idea, if that is the case, he will definitely be able to see it more clearly."

"Will it be distorted at a distance of only one foot?"

Ji Huan had already considered this issue first.

After all, it is affected by a convex lens, just like when many people use a magnifying glass, the characters in the middle will be magnified, but the characters in the edge will inevitably be distorted.

This problem, just think about what a convex lens is, it is inevitable.

The dome is fixed, and the people below can only stand in the middle to watch, and the edge, if the angle is wrong, may lose the distance.

At present, all calculations related to the distance of astrology are based on visual measurement, and then fine-tuned with the data obtained from calculations. If there is the slightest difference, it may be a thousand miles away.

"This is always impossible."

Ji Mo is also helpless. In this situation, perhaps increasing the precision of the convex lens can be better, but... Errors and the like are always inevitable.

"Visual calculations are not wasteful, and the two phases confirm that there must be no worries."

Ji Changwei was on the sidelines to make up for his son. There are tools, but it doesn't mean that everything depends on tools. Manpower is always needed.

Ji Huan nodded slightly, that's true, but whether this is feasible is another matter, firstly, such a large dome is not easy to make, and because it uses crystals, if something goes wrong, the loss will not be the slightest Son.

Furthermore, if the ground is broken directly on the observatory, the observatory will not be able to be used for a period of time, and the impact will not be small. If it is to be done, another observatory must be built at the same time.

He was full of thoughts here, and he didn't speak for a while, Ji Changwei and Ji Mo made eye contact, but neither of them quite understood what the other meant.

When Ji Huan came to his senses before speaking, the two of them hurriedly waited.

"There is a land of fallen stars nearby. Your father and son can go and see it together. If you can find it, it will be a credit."

All things in the sky belong to the Si Tianjian, and the same is true for meteorites that fall from the sky to the earth.

This kind of thing does not necessarily require Si Tianjian to send someone there. They calculate the location, and when they are roughly sure, they will let the local government look for it.

This time, it was also because there happened to be a star falling nearby, so I wanted to take a look.

Although they often think that the stars have their own masters, and the gods must be transformed into human beings, what kind of temperament and clothing must be, but they are not unaware of the fact that the material of meteorites is mostly spherical, that is to say, these stars It's not necessarily that they don't know the true face of him, it's just that they have another explanation.

Just like when a person dies and burns, there may be residues in the ashes, and meteorites are just the product of the residues magnified several times, which can also be seen.

However, meteorites have different materials, meteorites, meteorites, and a combination of them, which can also be used as a brief explanation for the divine nature they listed.

In short, it can always justify itself.

"Yes."

Ji Mo was a little excited. He had never really seen this kind of meteorite. Although he knew that those meteorites might not look so good, they were just like stones. Maybe the surface would be full of holes, like the surface of the real moon. ...

"It's such a hard job."

Only when he was away from Ji Huan's eyes did Ji Changwei dare to complain.

Seeing Ji Mo looking sideways, Ji Changwei patted him on the forehead and said, "It's because your calculation results were too perfunctory, which caused me to be implicated by you, and I was punished along with it."

"How can you be punished?" Ji Mo was curious about the meaning of these words.

"You'll know when you go."

Ji Changwei looked very experienced, glanced at him, and didn't say much.

If there are people living in the place where the meteorite falls, there will be a report early on. These things, it may be said that they are auspicious and first-class. In a peaceful and prosperous world, no one will cause chaos. Naturally, there is nothing to look for. When they arrive at the place, the local government Just hand things over to them and you're done.

But if the surrounding area is remote and uninhabited, it is really a hard job to pick up stones. Think carefully about the possible size of the meteorite, and how it will look if it falls a little less, and then screen all the stones on the nearby ground. After a whole day, I can't straighten my waist, which is very tiring.
