Chapter 162 Request
Any even number (natural number) can be written as 2n, where n is a natural number. 2n can be expressed as the sum of a pair of natural numbers in n different forms.
2n=1+（2n-1）=2+(2n-2)=3+(2n-3)=…=n+n, filter out inappropriate natural number pairs...
Sitting behind his desk, Wu Tong's thoughts extended as he wrote the deduction process on the draft paper. Mathematical symbols flew in his mind, forming formulas with unique mathematical aesthetics, which appeared on the draft paper from Wu Tong's pen.
·········
It took Wu Tong three days to reach the 3+4 deduction stage. Through his own deduction, Wu Tong had a deeper understanding of the Goldbach conjecture and the sieve method.
Although I haven't figured out how to prove 1+1, I should be able to do it with my current accumulation and some small progress. If my thinking is smooth, maybe I can achieve some interim results?
I wonder if it is necessary to provide regular progress reports after the project is launched?
Wu Tong discarded the fleeting thought and continued to immerse herself in the deduction.
Wu Tong never disliked slow progress and moved forward slowly. No matter how slowly the turtle crawled, it could reach the finish line. It was just a matter of time. Wu Tong deduced methodically without a trace of anger.
As I was writing the next step of deduction, the phone rang.
It was the ringtone of a confidential phone. Wu Tong took out the phone and frowned slightly when he saw it. What happened to Weilong?
"Teacher Lu!" Wu Tong answered the call immediately without hesitation. "Is there anything the project team can do that I can assist you with?"
"Wu Tong, are you in Peking University now? Is the time convenient for you?" Lu Xiao's voice came from the microphone, and from the sound of it, he didn't sound anxious.
Wu Tong felt relieved. "Yes, I'm at the Mathematical Research Center, Mr. Lu."
"We're going to Peking University soon. We need to visit you about something, but it's not convenient to talk on the phone. Can we meet at the Chenglao Research Institute?" On the street outside Peking University, in an inconspicuous-looking car, Lu Xiao said as he looked at the outline of Peking University that could be seen in front of him.
Next to him, there was a middle-aged woman with a serious look. They were in a seven-seater commercial vehicle, with the front passenger seat and three people in the back seat. With her straight back and special condition, it was obvious that she was not an ordinary person.
Cheng Lao's research laboratory is also the safest and most convenient place nearby.
"Okay, I'll be there right away!" Wu Tong didn't hesitate. After hanging up the phone, she headed for the Institute of Materials. The School of Mathematics was quite far from the School of Materials. When she arrived, a car was approaching from afar and stopped in front of the Institute of Materials. Mr. Cheng was already in front of the institute.
"Teacher!" Mr. Cheng nodded and looked at the parked car.
"Mr. Cheng, Wu Tong!" Lu Xiao pushed the door open and got out of the car, greeting with a smile, "Sorry to bother you!"
The door on the other side was pushed open simultaneously, and Elder Cheng nodded and smiled at the person getting off the car: "Boss Hua, welcome to the Beijing University Materials Research Institute! Wu Tong, this is Hua Yanxing, Boss Hua, currently the chief designer of PL air-to-air missiles!"
Old Cheng turned his head and whispered to his young disciple that Lu Xiao wanted to borrow his research institute to discuss something and had also informed him in advance.
"Hello, President Hua!" Is this the Iron Lady? Wu Tong admired and put himself in the position of a junior. He respectfully stepped forward and shook hands with Hua Yanxing. While they were greeting, several other comrades in charge of protection work in the car had quickly got out of the car and quietly set up defenses around the perimeter.
"Hello, Wu Tong, excuse me for disturbing you. It was me who asked Lu Xiao to bring me to visit you!" Hua Yanxing simply held Wu Tong's hands. Her eyes were bright. If the place was not wrong, she would have liked to pull Wu Tong aside to discuss how such an amazing ballistic-breaking trajectory was deduced.
It took her group of researchers about ten days to study and fully understand it. It took her nearly five days to fully understand it.
One can imagine how shocked she was when she learned that this ballistic trajectory was actually deduced by a little girl!
Only those who play with missiles know the value of this ballistic trajectory. When she first saw it, she felt it was extraordinary. After studying and understanding it, she was even more amazed and shocked. She only allowed core personnel to participate in studying the basic part.
This information can be directly elevated to the level of state top secret!
She initially thought that it was Lu Xiao who came up with it, and immediately rushed to the 606th Institute to discuss the specific implementation plan with Lu Xiao. However, when she arrived at the 606th Institute, she realized that the information was actually created by this genius child.
It involves a confidential list. If she did not have sufficient authority, she would not be able to know about Wu Tong's existence and meet Wu Tong in person.
"Let's go in and sit down first. It's not convenient to talk outside!" Old Cheng looked around. Fortunately, it was class time and there were not many people outside. However, it was not suitable to stay for long.
After opening the door of the institute, Cheng Lao led a group of people into his office and sat down. "I'm offering you some Keemun black tea from Lao Pan. Wu Tong gave me a box as a token of his respect. I don't know how to make tea, and I don't have all the utensils. We can just make black tea with hot water, so let's make do!"
Cheng Lao didn't let Wu Tong do it. He grabbed the teapot and made some tea and brought it over. Lu Xiao took it and poured the tea into the cups smoothly. "I still have some skills I learned when I was young. When I have time tomorrow, I will make you some tea!"
When he was young, he was a little unstable, and was forced by his father to learn calligraphy and tea ceremony. Over the years, he has not given up on them. When he has no ideas or inspiration, or is upset and impetuous, he will use them to calm his mind.
"Mr. Cheng, we are not strangers, so I won't say those lies. Let's not rush. I'm here to ask Wu Tong for help!" Cheng Yanxing was swift and decisive, and went straight to the point. "Wu Tong, the gift you gave to Weilong is really a great gift. Weilong's engine parameters and materials come from your assistance. Can you help me make some optimizations based on PL?"
The anti-ballistic design had already amazed her, but when she learned about Wu Tong's outstanding contribution to the Weilong project, she was even more shocked and delighted at the same time. As for the PL series of air-to-air missiles, they were already doing preliminary research on the PL-15, but the progress was not very good, and it seemed as if they had reached the end.
However, she was certain that they had not reached the end. She supported the project and insisted on continuous experimental research. It was just that they seemed to be stuck in a vicious circle of thinking and needed to be forcefully broken.
If the ballistic simulation design allowed her to see the PL-15's unpredictable miracle of easily breaking through defenses, then she was even more surprised to see the optimized parameters provided by Wu Tong for WS-15S, which almost doubled the WS-15S data.
Her first thought at that time was, could PL-15 ask this child to take part in the research and development so that their air-to-air missiles could soar into the sky like a mighty dragon and become a world-class sword of national deterrence?
