Xueba, I beg you to go and escort him quickly!

group!

Very quiet!

Xu Heng chatted for more than half an hour, and was also sleepy.

Put down the phone, yawned and fell asleep.

I feel dawn.

Dean Nie came to pick him up.

Xu Heng happily went.

He was looking forward to this research institute.

When the car slowly drove into the huge research institute, Xu Heng was a little surprised.

The architectural environment is not as tall as imagined!

Dean Nie, "Do you feel that it is too far from the film and television works?"

Xu Heng smiled.

Dean Nie, "The Institute of Physics was established relatively early, and it is divided into many types of institutes, such as geology, biology, atmosphere, space, etc. Which one do you want to visit first?"

"Oh, by the way, today in the space academy, there is a lecture by a researcher from the National Space Center, which is a once-in-a-lifetime event."

Xu Heng is not in the mood to listen to what Dean Nie is saying now.

【Ding!Check in at the Institute of Physics of the National Academies!Obtained SSS assessment]

Dean Nie, "Student Xu Heng, student Xu Heng?"

Xu Heng came back to his senses, "Ah? Hmm! Hmm!"

So Dean Nie thought that Xu Heng nodded in agreement, so he took Xu Heng to the space academy, and first listened to the lectures from the research fellows of the space center.

"I think we can talk about something more interesting today..."

"Space shuttle, manned on Mars..."

"..."

"But at present, before space exploration, there are several problems that have been bothering us."

"The launch of a space rocket costs a huge amount of money..."

"..."

On the podium, the research fellows are very talkative.

His entry point is very weird, very different from some previous speeches.

Xu Heng became slightly interested.

He looked at Dean Nie, "Dean, if the rocket can be landed and recovered, will this be considered a great value in disguise for the aerospace industry?"

Can save cost, naturally is to create value!

Dean Nie was stunned.

He looked at Xu Heng, and then at the podium.

Yes!

Although the academician on the podium is talking about this matter with many students in the academy, is your idea, Xu Heng, too unrealistic?

Dean Nie smiled, "There is no trace of the falling off track of this thing at all! It's not like a car or train!"

"The recycling you mentioned can indeed save costs and generate value in disguise, but first of all, we must have something that can be recycled, right?"

"Besides, let alone us, not even any foreign country has such technology."

"In addition, many academicians have considered everything you can think of, but the calculations involved in mathematics, theoretical physics, and other aspects of knowledge are too huge!"

While Dean Nie was talking, Xu Heng got up slowly, and left with a bow.

This surprised Dean Nie.

Followed to chase out!

"Xu Heng, what do you mean?"

Xu Heng smiled, "I think it's better to visit the courtyard than to listen to lectures inside."

Dean Nie had no choice but to take Xu Heng for a stroll.

And Xu Heng didn't just look at it casually. In the Institute of Space Research, he learned about the weight-to-weight ratio data of rocket reasoning, and a series of other accurate information related to space rockets.

Dean Nie and Xu Heng were not idle all morning.

At noon, Xu Heng found a pen and paper.

Dean Nie, "???"

He leaned over to take a look, the pile of numbers on Xu Heng's paper made him puzzled.

He didn't know what Xu Heng was calculating, let alone why Xu Heng calculated these complicated and strange formulas.

And Xu Heng was still muttering, "When the rocket is close to the apogee, use the universal joint to drive the engine to apply torque, and perform a gravity steering maneuver, which can flip the rocket to a high degree..."

"Reuse a proportional-integral-derivative controller to minimize the spread of the touchdown point..."

"..."

Because it was in the cafeteria of the research institute, Dean Nie couldn't get up and stand beside Xu Heng to listen.

In addition, the cafeteria was quite noisy, so he couldn't hear what Xu Heng was talking about at all.

He thought that Xu Heng was shocked after visiting the Space Academy.

Suddenly, Xu Heng stopped.

"It can't be calculated with this piece of paper alone, let's do it systematically after eating!"

Xu Heng came back to his senses, clenched the paper in front of him into a ball, and threw it into the trash can.

"Let's eat! Dean Nie."

Dean Nie looked at Xu Heng, "I've been waiting for you for a long time! So, are you busy?"

Xu Heng, "I'm not too busy, I'm just scribbling."

After regaining his senses, Xu Heng realized how unbelievable his SSS rating for physics was!

With a little thought, writing and drawing, Xu Heng can theoretically solve many researches that are currently impossible for many scientific research teams to complete!

"Dean, I want to go to the self-study classroom. Of course, before that, I have to buy a notebook and a pen."

Dean Nie accompanied them.

But when he got to the study room, Xu Heng said, "Dean Nie, I may have to stay in there for a few hours, you can go to your own affairs first."

"I'm done, call you."

Dean Nie, "Okay! I happen to have something to go back and deal with!"

Seeing Xu Heng go to the self-study room of the Institute of Physics with a pen and notebook, Dean Nie felt strange.

"This Xu Heng, what's going on? During the visit, his focus was different from others! I went directly to the study room in the afternoon... Shouldn't I be more interested and visit again?"

"Even if he lost his interest, he has opened his eyes. Shouldn't he seize the opportunity to learn more about the research institute?"

"Hey... I really can't figure it out."

Dean Nie left.

Xu Heng sat down and continued the theoretical calculations he had not completed at noon.

one page...

two pages...

three pages...

……

five pages...

……

ten pages...

Some calculation formulas will take two or three pages.

If it were someone else, even an academician of the research institute, I'm afraid they would have to struggle with these data for several hours, or even longer.

And Xu Heng's thoughts didn't stop.

Because this is mainly based on theoretical research, after these theories were confirmed, Xu Heng suddenly realized, "Even with these theoretical calculations, can the current level of technology be achieved?"

"I think it shouldn't be impossible!"

More than 20 pages of eloquence!

When Xu Heng finished writing, he threw the notebook into the free sharing column in the study room.

This is convenient for the teachers and students of the entire institute to better communicate with each other and exchange views.

Under normal circumstances, the person who expresses his opinion will leave his name and date, and then if someone is interested, he will also express his opinion on it, and then leave his name and date.

But Xu Heng didn't.

He didn't even leave his name, and after he put the thing up, he left.

In fact, what Xu Heng enjoys is this theoretical proof and the calculation process!

After all, we have all come to the Space Academy and visited it, so we can't waste this opportunity!

"call……"

Xu Heng stretched his waist, walked on the road of the research institute, and contacted Dean Nie.

That's an understatement!

That's how he left the Institute of Physics so calmly.

Dean Nie asked in the car, "Xu Heng, so what did you do in the study room?"

Xu Heng, "I wrote something, I hope someone can resonate with me!"

Dean Nie smiled, "I thought about it when I went back. You probably want to communicate and explore with the teachers and students of the institute!"

Having said that, he never expected that Xu Heng would theoretically calculate and recover the rocket booster!

Available in the Institute study rooms.

Xiao Sanshi, an academician of the Institute of Physics, discovered Xu Heng's notebook.

This is a brand new book!

Among the shared notebooks on one wall, Xu Heng's notebook is new!

And this new notebook is the only new notebook in the past week.

Xiao Sanshi's eyes lit up, because he had read and understood every booklet hanging on the wall, and even left his own opinions in many booklets.

"Finally some students came up with new ideas."

He opened it and took a look. On the first page, it read: "Rocket Reentry and Reverse Propulsion"!

Xiao Sanshi, "???!!!"

"Such a difficult subject is beyond my expectation. This classmate is really courageous!"

He affirmed Xu Heng's courage, of course, this is the only thing he can affirm at present.

But when he opened the second page to read...

page three……
