Wu Qitian saw that the old man was directly furious, touched his nose, and said with a wry smile: "Teacher, even if you want to have a good talk with Mr. Lin about the repeated launch technology, do you have to let the family sit down first?" ”

Lin Dong listened to Zhile, this is good, dare to love the home of the adult family here?

When Qin Xiangjie heard this, he reluctantly took a step back and returned to the place where he was sitting and sat down, but his eyes were still staring at Lin Dong, as if he was afraid that he would run away. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

Lin Dong sat opposite, and after the secretary brought the tea, he quietly retreated, and Wu Qitian said with a smile:

"Mr. Lin, don't be surprised, Mr. Qin doesn't have an opinion on you, the main thing is that he has been paying attention to domestic rocket engines and repeated launch technology since he retired. Recently, I heard that the foreigner's 'Blue Origin' and the launch of the Falcon rocket have been carried out many times, not only in the experiment of the reuse of the first-stage rocket, but also in the experiment of the spacecraft escape pod, the teacher is anxious, and I heard that you can have rocket relaunch technology here, he felt that it was not credible, so he ......"

Lin Dong nodded, it is understandable that an old professor who has retired, heard that a hairy boy has a technology that the older generation of them have studied all their lives and has not unraveled, and it is inevitable that he will not believe it. The beliefs of this group of people are quite firm, and they are the backbone of the construction of the republic, and it can be said that without their perseverance, the republic's current development and growth would not have been possible.

However, their persistence has also made them have a very stubborn habit, and many things need to be seen in person and verified to be believed.

They developed a complete set of industrial systems in China from the stage of poverty and whiteness, and the process of starting from scratch, the kind of hardship, people today simply can't imagine -- there was no Internet at that time, and it was not the era of the information explosion. A lot of seemingly simple common sense that can be found on the Internet now requires the older generation to give full play to their imagination and accumulate a knowledge system little by little in that era, especially after the withdrawal of the old Maozi experts in the north.

For example, today's middle school students, as long as they know how to use the Internet, can search the Internet for things like the principles of atomic bombs, and even find improvised nuclear explosion operating devices.

However, in those days, with no basic knowledge, no experimental data, and no mentors, it was necessary to develop some technologies that had been mastered by Western countries but were blocked from China, requiring huge imagination, painful calculations, and self-overthrow over and over again......

At that time, there were no computers, and people who went to school in the eighties of the last century generally knew what calculus was, and without computers, in the fifties and sixties of the last century, a large amount of data needed to be calculated with an abacus, what kind of concept was that?

……

Although Lin Dong did not grow up in that era, he actually had high respect for the people of that era - some time ago he was engaged in the construction of the scientific research system and laboratory construction of Changying Group, and he met a lot of such old-timers - although they had such and such titles, Lin Dong still felt that it was extremely cordial and comfortable to call them old-timers.

These people are stubborn, old-fashioned, and want to save face, but they have a pure patriotic heart for the republic, and they desire the strength of the republic more than the young people of today, because they have no one to teach them when they are young, so they are good teachers. Because they are now old and know that their time in this world is running out, they are eager to pass on the knowledge they have mastered, so they will be very strict with young people.

Although there is a generation gap, Lin Dong can understand.

Wu Qitian saw that both sides sat down, and then said to Lin Dong: "Mr. Lin, Professor Qin was my mentor when I was a graduate student, and I was anxious when I heard me talk about the technology of repeated rocket launches you talked about yesterday. In fact, we know Changying Group, and we are quite impressed by the technologies you have researched before, the original intention of the teacher is not to find trouble with you or not to look at you, mainly because I feel that the momentum of the development of Changying Group is so good, we should not be ambitious, to pursue what extraterrestrial technology is the same as foreigners, and do a good job of the current project, lay a good foundation step by step, and have the opportunity to study more advanced technology in the future......"

"You don't have to put gold on my face!" Qin Xiangjie interrupted Wu Qitian's words dissatisfiedly, "How old are you, you can talk so many twists and turns, no wonder you can't make achievements in professional technology, your mind is used in these, it's strange that you can still have development!" You just say it to him, and I don't believe what he says he knows about this technology! Young people should be down-to-earth, and they can't just know what their last name is if they have a little achievement......"

Lin Dong listened and felt Coke in his heart. Although the teacher is older, like Lao Jiang, the older he gets, the hotter he gets; Middle-aged Wu Qitian was polished out of his sleek temperament by life. Although Qin Xiangjie said that he was dissatisfied with Wu Qitian, he could see that it was just lip service, and there may be regrets, but the dissatisfaction must be just talking.

Wu Qitian respected the teacher very much, and as soon as Qin Xiangjie said it, he didn't refute it, but just smiled apologetically at Lin Dong.

Lin Dong knew that if he didn't come up with some dry goods, he was afraid that Old Man Qin's dissatisfaction would continue, so he raised his hand and interrupted what Old Man Qin was about to say: "Professor Qin, it's not that I don't know that the sky is high and the earth is thick. I can let Lao He tell you that I have the technology to launch rockets repeatedly, so naturally I really have it. Although these techniques are only theoretical, they are also real, and although we boys are not as insistent as your older generation, I must have this technology here, and I don't lie to you. ”

Lin Dong's words were very indifferent, but Qin Xiangjie didn't sound indifferent, he was stunned for a moment, and then said to Lin Dong: "Young man, you have a great reputation, I know this. The things you've made are technologically advanced, and I believe that. However, the repeated use of this technology in rockets is not just as simple as saying, I have seen a lot of people, many people say that they understand this principle and know this technology, but these things are really used, it is not the case at all, even if it can be explained theoretically, but in practice there are many examples that cannot be operated ......"

Lin Dong nodded: "I know." ”

"You know how dare you say that?" Qin Xiangjie was really angry this time, "Don't you know that without experiments, this kind of rocket technology cannot be said to be insurance at all, you can't have an experimental field here, and you can really guarantee that those theories of yours can be practical?" Young man, I would like to advise you again, be down-to-earth! ”
