Chapter 614: Principles and problems

Walking into the familiar compound and following the usual path, Tan Zhenhua returned to the gray building No. 9. For some reason, he suddenly felt that his footsteps were a bit heavy. Is this the legendary "near nostalgia"?
Although this is not the first time he has left home for a long time since his rebirth, and then returned, why does he feel different this time?
Looking at the dim yellow light from the familiar window, he took a deep breath, settled, and finally took a step forward.
"Dad, Mom, I'm back."
Tan Zhenhua finally opened the door, concealing his excitement with as cheerful a tone as he could. However, when he opened the door, he was surprised to find that there was no figure of his mother Xu Yun in the house, but the house was full of people. people.
At the door, he saw the group of people in the house with a dazed effort, but he didn't know it. At first glance, it was really shocking.
Of course my father, Tan Ming, was there, and the neighbor’s uncle Ben Fang was also there. It’s not unusual for these two to appear here. It’s common for neighbors to hang out, but it’s surprising that Director Zhou is there. Now, not only is he here, but also the chief technical officer of the firm, Mr. Zhang, as well as the military representative Wang Zetian, and the director of the confidentiality department Liu Dakai-well, the director of Liu Dakai is also a newly promoted official, and he has not had time to sit. Hot—Of course, there is the crip who doesn’t miss this occasion.
With such a large group of people crowded in this small room of their own, they were plotting something ulterior, Tan Zhenhua quickly coughed twice and apologized: "Ahem, sorry, I don’t know you are in a meeting. Ah, I'll go back to my room, you go on, go on."
He just turned his head and wanted to slip, but there was a violent shout behind him: "Fucky boy, where are you going? Is it polite to see so many elders who don't even say hello?"
Dad has spoken, how can I hide? He had to turn around, changed a respectful attitude, and greeted the few present. When it was the last turn of the lame man, he saw him winking at himself in a narrow-minded manner. The alarm bell in his heart immediately rang, and it's over, it must be no good!
Sure enough, when he finished saying hello one by one and wanted to slip again, Dad stopped him again with a scream: "Don't slip, you can tell me clearly, where did your notebook come from!"
While talking, Tan Ming copied the soft side of a black cover in his hand to him.
Knowing that this was indeed the case, Tan Zhenhua sighed in his heart. He had known for a long time that once this secret book was born, it would inevitably cause a storm in the world, don't you think this is coming?
Fortunately, this situation had long been expected by him. Although the incident happened suddenly, it did not make him too panic: "Dad, this should be the note I asked Uncle Ben to bring back. I gave it to him at the time. He said it before? The content here is compiled from public information from various channels when I was in school in the United States. I think it should have some inspiration for our radar research and development, so I just ..."
Before he could finish his words, Tan Ming interrupted him and said angrily: "You don't tell the truth, you are my child, and I will know what you are going to pull as soon as you push your ass. Shit, you just lied to the ghost, and you collected it through open channels. Who did you lie? I don’t believe that the U.S. countryman can be so generous, and even the top technology of the phased array has been disclosed? I’m telling you, brat. The content involved in this notebook is too sensitive and will directly affect our exploration of the future direction of radar technology. If you do not explain the matter today, it may have an extremely significant impact on our institute and our country!"
No matter how bad the attitude of Tan Mingxun's son is, it is only natural. Is it Chinese tradition, but some people still can't stand it.
Ben Fang stood up and said, "Lao Tan, don't be too harsh on Zhenhua. Zhenhua is a good boy. You don't know what he did during his stay abroad. Also, you took it not long ago. But he still has a credit for the award, Director Zhou, don’t you think?"
Director Zhou immediately replied: "Ben Gong, you are right. I said Lao Tan. Your son is really upright. He has first-rate academics. Is he the first foreign student in our compound? Stanford, a famous American school, can make money so much. I have heard the gossip that your son’s net worth is about to catch up with our China National Treasury. If I want to have a son like you, I can wake up in dreams."
Mr. Zhang also smiled and said: "Yeah, Old Tan, tell me how did you raise your son? If I want a son like you, I have to hold it in my hand all day for fear of falling. Afraid of it?"
While he said, he beckoned to Tan Zhenhua and said, "Come on, sit here, Tan Xiaozi, come to your Uncle Zhang."
Tan Zhenhua, who is known as an honest and cute little man, didn't he just leaned over immediately when he saw this? Then when he peeked at his father, he found that Lao Tan was too awkward to mention-on the one hand, his heart was already happy, and on the other hand, he had to pretend that his son was not a good tool. The expression that was about to be stretched was too much. How awkward it is.
Mr. Zhang greeted Tan Zhenhua and sat down beside him with a smile, and said with a smile: "Zhenhua, your dad is famous for his bad temper, and he hasn't grown in decades, but you won't blame him if you want to come. Right? But what he just said is correct. Come and tell you Uncle Zhang, how did you get this notebook? You should know that there are too many technical routes in this notebook. If we make a mistake with reference to this unknown thing, the trouble will be great."
When Mr. Zhang said that, Tan Zhenhua immediately understood a major event. It turned out that he had made a huge mistake that he should never have done!
When he wrote this notebook, he wished wishfully that the radar experts of the 4014 Institute would surely gain the treasure after seeing this notebook and continue to research and develop according to the route he gave, but he completely forgot, engineering The two most important principles in the field of scientific research-theoretical provenance and practical test!
The brothers who have written graduation thesis know that all the arguments and arguments cited in the thesis must be indicated in the attached page of the thesis. This is a respect for the predecessors who created this argument. On the other hand, it also shows that this argument and argument have been proven correct.
And for the predecessors have not proved the correct view? Then, experiments must be used to prove its correctness.
Give an example to illustrate the importance of these two principles.
In 1960, it was a critical moment for China to study its first atomic bomb.
Following the antagonism between Soviet Russia and China, the Soviet Russia withdrew all the experts in aid to China, including of course the group of people who supported China's atomic bomb research.
However, after the Soviet-Russian experts withdrew, Huaxia discovered that in the lecture notes of the Soviet-Russian experts that they had kept through various means, there were several technical indicators that were quite different from the theoretically derived parameters.
In order to verify these technical indicators, the Second Ministry of Machinery quickly organized a manual check of these parameters, and the results of the first check showed that the technical indicators left by the Russian experts were wrong!
Since there is not enough evidence to prove that the technical indicators left by the Soviet Russian experts are wrong, China can only verify these formulas over and over again. You must know that this calculation is extremely large, and China at that time can be used to help Only the abacus and slide rule are calculated!
After a whole year and up to nine calculations, and a nuclear physicist from China used other theories to disprove the mistakes of the Soviet Russian experts, China finally accepted the results of the calculation team, and it was the success of the China atomic bomb. Test burst.
This shows the importance of the two most important principles of theoretical provenance and practical testing in the field of engineering research.
But when he wrote this notebook, he did not have enough reference materials on hand for him to look up and mark the correctness of the arguments and arguments he cited, nor did he have enough experimental data to prove some of the things he mentioned in the notes. The verification result of the scheme is the same as theoretically deduced. After all, most of the content he described in this notebook is still cutting-edge technology that has not been touched by 4014. He can never write in the notebook "I will do this experiment. After that, the conclusion is correct. Well, as for the time of the experiment, it will be about twenty years later, right?"
Those who are qualified to read his notebook are all big cows in the radar industry and real explorers in the field of engineering practice. They can never easily believe the contents of this notebook, even if Tan Zhenhua uses his brain to guarantee No way!
Just like Mr. Zhang said, if this notebook is really of unknown origin, and they follow the technical route described in this notebook, what if it is wrong? All previous efforts are light!
Tan Zhenhua wanted to understand this, and at the same time a difficult problem naturally lay in front of him. How can I prove to these few that all the contents in this notebook are correct?
