Any even number (natural number) can be written as 2n, where n is a natural number. 2n can be expressed as the sum of n different pairs of natural numbers.
2n=1+（2n-1）=2+(2n-2)=3+(2n-3)=…=n+n, filter out unsuitable natural number pairs...
Sitting behind his desk, his thoughts extended. Wu Tong wrote the deduction process on the draft paper, which gradually spread and extended. Mathematical symbols flew in Wu Tong's mind, forming formulas with unique mathematical aesthetics, which were presented on the draft paper from Wu Tong's pen.
·········
After three days, Wu Tong had reached 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 yet, with my current accumulation and some small progress, I should be able to do it. If my thinking is smooth, perhaps I can produce 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 despised 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 in an orderly manner without a trace of anger.
While 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 without hesitation. "Is there anything the project team can help me with?"
"Wu Tong, are you at 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 seem to be in a hurry.
Wu Tong's heart relaxed a little, "Yes, I'm at the Mathematical Research Center, Teacher Lu."
"We are about to arrive at Peking University. We need to visit you about something, but it is 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 was already visible in front of him.
Next to him was a middle-aged woman with a serious expression. 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 appearance, it was obvious that she was not an ordinary person.
Cheng Lao's laboratory is also the safest and most convenient place nearby.
"Okay, I'll be right there!" Wu Tong said without hesitation. After hanging up the phone, she headed for the Materials Research Institute. The School of Mathematics was quite far from the School of Materials Science, and when she arrived, a car pulled up in front of the Institute. Elder Cheng was already there.
"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 opened simultaneously, and Elder Cheng nodded and smiled at the person getting out of 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 the PLA air-to-air missile!"
Old Cheng turned his head and whispered to his young disciple that Lu Xiao wanted to borrow his research institute to discuss something, and he also informed him in advance.
"Hello, President Hua!" Is this the Iron Lady? Wu Tong, in awe, placed himself in a position of juniority, respectfully stepped forward and shook hands with Hua Yanxing. While they were greeting, the other comrades in charge of security had already quickly gotten 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 here to place yours!" Hua Yanxing simply held Wu Tong's hands. Her eyes were bright. If the place was not wrong, she would have wanted to pull Wu Tong aside to discuss how such an amazing defense-breaking ballistic trajectory was deduced.
It took her group of researchers about ten days just to study and fully understand the concept. She herself also spent nearly five days to fully grasp it.
It is conceivable how shocked she was when she learned that this ballistic trajectory was actually deduced by a little girl!
Only missile experts know the value of this ballistic trajectory data. When she first saw it, she was struck by its extraordinary power. After studying and understanding it, she was even more astonished. Only core personnel were allowed to study and research the basics. This data could be directly classified as a state 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 found out that this information was actually created by this genius child.
This involves a confidential list. If she didn't have sufficient authority, she really wouldn't 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 to the research institute, Elder Cheng led his group into his office and sat down. "To offer a gift to the Buddha, Old Pan gave Wu Tong a box of Keemun black tea. Wu Tong gave me this as a token of his gratitude. I don't know the intricate techniques for brewing tea, and I don't have all the utensils. We can just make hot water for black tea, so let's make do!"
Cheng Lao didn't let Wu Tong do it. He grabbed the teapot, brewed some tea, and brought it over. Lu Xiao took it and poured the tea smoothly into the cups. "I still have some skills I learned when I was young. When I have time tomorrow, I will make you some tea!"
He was a bit unstable in his youth, and was forced by his father to learn calligraphy and tea ceremony. Over the years, he has not given up on them too much. When he lacks ideas or inspiration, or feels upset and impetuous, he uses them to calm his mind.
"Mr. Cheng, we're not strangers, so I won't spout those empty words. Let's not rush off. I'm here to seek Wu Tong's help!" Cheng Yanxing was brisk and decisive, going straight to the point. "Wu Tong, the welcome gift you gave Weilong is truly a great one. The engine parameters and materials for Weilong came from your assistance. Could you please help with some optimization based on the PL?"
The anti-defense ballistic design had already amazed her, but when she learned about Wu Tong's outstanding contributions to the Weilong project, she was even more shocked and delighted. Regarding the PL series of air-to-air missiles, they were already conducting preliminary research on the PL-15, but the progress was not very good, and it seemed as if they had reached the end of the road.
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 Wu Tong provided for the WS-15S, which almost doubled the WS-15S data.
Her first thought at the time was, could PL-15 ask this child to take part in 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?
