On the ground, young people who choose aerospace-related majors have strong personal interests. Interests can drive them to study hard and practice hard. At the same time, the major itself also has entry screening, and mathematical ability is one of the thresholds. Those who are unqualified have no chance at all.

.

But living in the sky, everything is different. Everything related to aerospace permeates everyone's life. At the basic education stage, it is time to consider aerospace-related content. A set of mathematics tutorials, how to make people who have no interest and no

Can a talented person achieve the basic qualities of space navigation?

There are a lot of existing teaching materials for various languages ​​on the earth. There are not a few people who give up after just one glance. This can easily achieve the purpose of dissuading students.

Even if there are no difficulties, difficulties will be created, otherwise it will not be enough to prove the high level of the teaching materials.

When Lan Ze was looking for books for his sons, he came across a preschool mathematics book with a strange idea. He just explained the factoring method to the children clearly, and told them that numbers that no one can factor except one and themselves are called prime numbers; then,

Just insert a section of "Extended Knowledge" to explain how to prove: any natural number greater than 5 can be written as the sum of three prime numbers.

This thing is not difficult to prove. That is to say, starting from the time Goldbach asked the great god Euler for help in 1742, it has trapped the mathematical world for more than three hundred years.??

It must be admitted that even if the teacher does not understand the expanded content, a few gifted children can understand it and learn it.

Lan Ze reached out to his side in annoyance and rubbed Mo Mo's little head. The children were circling their parents on the ground.

Mo Mo has long been used to being touched on the head suddenly. He grabbed his father's hand and slid it into his arms. The child defied gravity.

Lan Ze stroked Mo Mo in his arms and felt that this New Moon textbook might need to be written starting from Mo Mo's mathematical ability.

Being a tutor for classmate Xiao Mu, he felt that he was still making do. Writing such a practical teaching material for students starting from the age of 3 to prevent students from being dismissed... Well, this question is too difficult.

Change the question. You can also change the players.

"In the past few days, I have been asking my brothers and sisters to find out if anyone has produced similar teaching materials."

"Don't be in a hurry. You can take your time to make up lessons for Xiao Mu. She is young and has plenty of time. I will make a list to show you the order in which we will arrange training for her. You can design courses for her based on this."

Zhang He is a bit similar to Feng Chuan, Lanze’s mathematics degree tutor. They are both very good at chasing ducks.

What Lanze is good at is laziness.

"...Okay. Let's see when we have time." He stood up with his son in his arms. "Momo, let's go play in the snow!"

There was a light on in front of the cafeteria. There were street lights on the road as well. But looking out the window, it was already pitch black beyond the light range.

The flying snow flakes successfully blocked the lights of the residences in the family area. Most of those apartments are underground. There is not much light emitted above the ground.

"Okay!" Mo Mo slipped out of his father's arms and rushed to the door, waiting for the adults to open the door for him.

"Hey! Stop here..."

As soon as Lan Ze pushed the door open, the wind blew in with snow flakes, and all Zhang He's words were torn into pieces by the wind. It felt even colder and biting outside than during the day.

It was snowing season, and it was at night, so the roads on campus were empty. Even the cars had hidden in the underground driveway. Xiao Momo raised his hand and turned on the headlight on his hood, running freely on the snow.

Xiao Jiang appeared from behind: "General Zhang has gone downstairs."

"Yeah. I know." Lanze smiled. "I want this child to remember more."

The wind, frost, snow, rain, heat and cold on the earth are not found in the space station.

There are no seasons there, only simulated environments. Warmth and coolness, thermal radiation and wind, and the circadian rhythm of light and dark and warm and cool are all artificial.

Mo Mo is different from his four brothers. At his age, he has settled on the space station, and the earth will only become more and more unfamiliar to him.

"Have you decided yet?" Xiao Jiang asked.

"I don't know... She has to make the decision after all."

Lan Ze picked up a ball of snow, squeezed it tightly, and shouted: "Mo Mo!"

Aim at Mo Mo and throw it out.

Mo Mo suddenly turned a corner and hid. Hearing the sound of snow, he turned around and took a look, running in the S shape even more happily.

When Lan Ze brought Mo Mo home, Zhang He had already taken a shower, changed clothes, sat on the bed, and continued to work.

She had already made a list of training courses and projected it on the wall.

Work is something you can't run away from.

Lan Ze poked his head into the bedroom and took a look, and was so frightened that he immediately shrank back. He continued to have fun with his youngest son, and then took a shower.

By the time I get to bed, I can officially go to bed.

"I have a suggestion." Lanze turned a blind eye to the stubborn projection on the wall. "Bring our two daughters with us. They can be moved to the development box soon. I checked the policy and found that the development box can be with one parent.

Go to Crescent City."

"I haven't said I'm going yet." Zhang He was a little annoyed.

"Go ahead, go ahead."

"I am still a Chinese soldier. I can continue to be a teacher in the aviation school, and I can be promoted to teach students without delaying anything. For me, even if I don't have real power in that position, I can still enjoy the respect of hundreds of thousands of people, not to mention the military and political affairs.

Grab it. Children, you can go back to earth to play during the holidays, and your growth will not be affected. It’s just you."

"Yeah." Lan Ze knew what she meant.

"The Supreme Leader cannot leave the Crescent so easily. I will not come back to see you again. Do you understand?"

"Get a divorce." Lan Ze said with a shy face.

Zhang He grinned.

"Bring our children up, I will watch you from below every day." Lanze climbed onto the bed and held his wife in his arms. "When they go, it's as if I went too."

"Don't you want daughters? Let them stay with you?" Zhang He tried to ask.

"No need. What if a mutation is detected? Once they reach adulthood on the ground, they will be trapped for the rest of their lives. I hope they are born free."

Lanze has four sisters who carry the mutation. Each has a different psychological quality and different tolerance.

As heartless as Orchid, and with the care of her good friend Lan De, she can still live happily even if she holds her children in the nursery every day. But not everyone is like her. Rand Shen's psychological depression is so serious

It affects endocrine and hair turns gray prematurely.

"Take all the children away?" Zhang He asked him.

"Take them all away."

Zhang He smiled:

"Then do you have enough children left to be exempted from the birth tax? I took all my sons away, and they are no longer people on earth."

Lan Ze's face turned red. But he still calculated carefully.

"That's enough. It just happens to be tax-free. This must be God's will."

Under the name of the fairy, there is Li Yixiao, who is ugly and stupid. Under the name of the painter, there is Lan Xuning, who is well-behaved and annoying, and there is another boy whose name he has never cared about. There are two more familiar sons.

mutation.

In fact, it doesn't matter if he doesn't have enough children. He can find someone to help him give birth right away.
