Scholar’s Starry Sea

"speaking of which, did I tell you the address of my home?"

After placing a cup of hot tea in front of Wu Bin, Bi Wanqing sat down with him Asked the other side.

"hehe, I was investigating sneakily, just thinking of giving you a surprise." Wu Bin said as he looked around.

I found that his teacher’s home is very simple and simple. In the living room, apart from the two small square chairs where they are sitting, there is an Eight Immortals table and a 26-inch TV. The simplicity is similar to his grandfather's home is almost the same.

"You have a heart." Bi Wanqing took a sip of the tea, then looked at Wu Bin and said: "Cooked Pu'er tea, try to see if you are used to drinking it."

"You are used to drinking it."

My grandfather also loves to drink tea. When I was a child, I drank it every day, and I slowly tasted the aroma of this tea.” Wu Bin finished taking a sip, closed his eyes and said, “Well, good tea.”

"Look at you pretending." Bi Wanqing shook the head with a smile.

"Oh yes, Teacher Bi, I brought the gold medal." Wu Bin took the gold medal out of his pocket and handed it to Bi Wanqing.

When the host dinner was over, he had already called the two teachers and told them the good news.

When Bi Wanqing watched the gold medal, Wu Bin told him some interesting facts about IPhO, as well as the trend of questioning and various answering techniques in the past two years. He was regarded as a person who came to the junior competition class. A gift from Brother junior sisters.

"Stay for dinner, your Aunt should be off work soon."

After drinking a pot of tea, Bi Wanqing glanced at the clock on the wall and said to Wu Bin.

"Although I really should pay a visit to Master, I still have to go to Teacher Cai's house, or see you next time I come?"

"Alright. "After Bi Wanqing finished speaking, he sent Wu Bin to the door, patted his shoulder and said: "If you want to keep working hard, I won't say anything like that. University should be your real stage. I believe you will go further and further. The more you go, the better."

"Teacher, you should also take care of your body. Don’t take care of your body because of the competition class."

"Don’t worry, my body I know it myself." Bi Wanqing nodded.

"Then...I will see you again, goodbye." Wu Bin waved his hand after speaking and walked down the stairs.

Teacher Cai's home is not far from here. Wu Bin stopped by to the supermarket to buy some dried fruit gift boxes and a box of milk and he arrived soon there.

Ranging the doorbell of 804, a mature female voice came out of the intercom.

"Hello, who?"

"Hello, my name is Wu Bin and I am a student of Teacher Cai. Is he there?"

"Oh~ I'm here, come on."

Opening the door, Wu Bin took the elevator to the 8th floor and met Cai Guoping with a smile on his face.

"Oh, our international champion is here. Peng Xun is brilliant."

Cai Guoping said with a big smile.

"That's not all thanks to your teacher." Wu Bin said, handing over the two boxes of gifts in his hand, "My mother asked me to bring them specially. Snacks, please let the teacher laugh."

"Oh, this child is really good at talking. No wonder our Old Cai says hello all day long." At this time, an Aunt wearing an apron came out and greeted Wu Bin said, "Come in, just made a table of dishes."

"Hello, Master." Wu Bin immediately shouted politely.

"Aiya, don't call me a teacher, just call Aunt."

"Hey, Aunt."

After saying hello, Wu Bin and Cai Guoping walked into the living room together. Compared with Teacher Bi's home, the decoration of Teacher Cai's home is warmer, and all kinds of furniture are also available. There is also a wedding photo of him and his wife hanging on the wall, which is very sweet. .

"I just returned to China, why don't you take a rest at home for two days, why are you here?" Cai Guoping said, opening the refrigerator door next to the kitchen, looking towards Wu Bin and asked: "Coke or ice tea? "

"The Coke is ready."

Cai Guoping was nodded, took out a can of Coke from the refrigerator and threw it to Wu Bin.

"I just want to show you the medals quickly." Wu Bin said after catching the Coke.

"What's so good about broken medals." Cai Guoping pulled a can of beer and took two sips: "After you find any new particles, new substances, you can bring them to me. Then I'm not in vain."

But at this moment, my wife immediately walked out of the kitchen and said: "The child gave you a gold medal for you to see. What are you talking about?" The head looked towards Wu Bin, "He, just like that, is dishonest. He's always telling me how good a student is at home, but you are his student. You probably understand his temper, right?"

Wu Bin smiled nodded.

"hahaha, just understand, do you like sweet and sour?"

Wu Bin is nodded again.

"That's good, then you can sit for a while, and the food will be ready soon." The mother returned to the kitchen after she finished speaking.

Cai Guoping, who has been silent for a long time, pointed to the kitchen, and made a very terrifying look of baring fangs and brandishing claws, making Wu Bin amused and laughed endlessly.

Cai Guoping also laughed for a while, took a beer and walked over to sit next to Wu Bin and asked: "Tell me, what are the more interesting questions for IPhO this time?"

"Is it interesting... There is a GPSsystem's relativity correction question which is very interesting."

"Oh? You will wait a moment." Cai Guoping said and walked back to the room, took out the paper and pen to put it away. At the table, "Interesting, show me the solution."

"Okay." Wu Bin nodded.

While Wu Bin was writing a question for Cai Guoping, Ms. Cai came out with a plate of pomfret in tomato sauce, put it on the table, looked at the two people who were serious about the topic, laughed, and went back to the kitchen. went.

“So assuming that there is only Earth’s gravitational field around Earth, without interference from other gravitational fields, and the Earth’s gravitational field is statically piled up and distributed, the formula can be listed according to Schwarzschild’s solution.”

Cai Guoping listened to the nodded of looked thoughtful, pointed to the paper and asked: "So if the derivative is less than 1, it means that the special relativity satellite clock is slower than the clock on the ground. If the derivative is greater than 1, it means the general relativity satellite clock. Is it faster than always walking on the ground?"

"Well, with the Physics formula, just substitute the relevant data for calculation."

"Interesting..." Cai Guoping said Then he moved the paper to him, "Give me the pen, I will count it."

"Okay." Wu Bin nodded handed the pen to Cai Guoping.

Cai Guoping just listed the two-line formula, and heard Ms. Cai who came out with a pot of small rib soup with a smile and said: "Looking at it this way, I don’t know who the two of you are the teacher anymore. "

Cai Guoping said indifferently after listening: "This kid is enough to be my teacher now. There is nothing wrong with it."

"Dare not, dare, teacher, you This is not ashamed to ask." Wu Bin waved his hand immediately.

However, Cai Guoping immediately patted Wu Bin on the head, "Stop shirking, just say that you are fine. Come and see if that counts."

"It's alright, the two universities ask home, eat first, and it's not too late to discuss after the meal."

"It'll be fine soon." Wu Bin and Cai Guoping said in unison.

Mrs. Cai also had to smile and shook her head, and sat down to eat first.

Ten minutes later, Wu Bin, who wrote the last line of calculations, put down his pen and said: "This means that the general relativity time on the satellite is faster than the clock on the ground."

"Because of the landmarks The gravitational field is stronger than high altitude, right." Cai Guoping nodded.

"Well, so in practice, GPSsystem's relativity correction is the result of special relativity effect and general relativity effect."

Cai Guoping thought for a while after listening, nodded and said:" This question is really good."

"Will you eat now?" Ms. Cai asked with a smile.

"Eat, eat, give this kid more." Cai Guoping put the paper and pen aside and said happily.

"I'll do it myself." Wu Bin said that he was about to stand up, but was immediately suppressed by Ms. Cai.

"The visitor is the guest. There is no reason for the guests to serve their own meals. Just sit down."

"Thank you, Master, oh no, Aunt."

Mr. Cai covered her mouth and smiled and said: "If you really feel that your mother is okay, just call her mother."

"Wow, the teacher is so kind. Hey, teacher, you are so blessed." Wu Bin looked at Cai Guoping and said.

"That is, your teacher is this." Cai Guoping said with a thumbs up.

Wu Bin also nodded with a smile.

During the meal, Wu Bin was shocked by Ms. Cai’s cooking skills. Originally, he thought that Mother Pei’s sweet and sour short ribs had balanced the sweet and sour taste. hand!

This pomfret in tomato sauce is so delicious that it won’t even be slapped!

However, after quickly eating a bowl of rice, Wu Bin was a bit sorry to add rice, so he stared at the empty bowl so stunnedly. The dilemma made Ms. Cai laugh so hard, she just smiled. I took Wu Bin's empty bowl and went to the kitchen.

"Thank you, Madam..." Wu Bin laughed shyly after taking over the filled rice bowl.

"Come and eat as often as you like. You're welcome, ah." Ms. Cai couldn't help touching Wu Bin's head, expressing her love for this shy big boy.

After dinner, Cai Guoping pulled Wu Bin onto the sofa next to him and sat down. While watching the news broadcast, he asked Wu Bin: "How about it, have you decided what major to study?"

"University of Science and Technology does not limit the selection of majors. In the freshman year, in addition to modern Physics and optical engineering, I also plan to listen to classes in materials science and polymer science. In addition, engineering and information technology. I'm also interested. If I have enough time, I should always go to the class."

"Is there a goal?"

"Goal? Do you get a full grade point?"

Cai Guoping raised his hand and wanted to give Wu Bin a look, but in the end he held back, "I'm the person who won the IPhO gold medal anyway, can the target be larger?"

"Oh, yes! I intend to make something on Physics, such as combining Quantum mechanics and general relativity into one to get a unified theory."

"Research on superstring theory Is it?" Cai Guoping asked.

"It's possible, but it's not just that."

"hahaha, this goal is good, very good!" Cai Guoping slapped Wu Bin hard twice," As long as you solve it, the dynamite prize must be yours, Aiya! If you want to be able to get the dynamite prize, let me tell you, I take the tweeter and go out to promote it every day."

"You want to promote him Have you won the Nobel Prize, or do you want to promote that the person who won the Nobel Prize is your student?" asked Ms. Cai, who was clearing the table on the side.

"Then I need to say, of course, it is to promote that this kid is my student." What Cai Guoping said is a sense of righteousness.

"You~ I'm not ashamed." Ms. Cai poked him with a finger with a smile.

"It's actually a fact." After Cai Guoping finished speaking, he turned his head and looked towards Wu Bin, "But there are targets far away, and there are no less close ones. Didn't you just say that you are interested in materials science? ”

"en. ”Wu Bin nodded.

"Then I will give you a development direction and study the mechanical "heart"."

"Heart... dirty? Engine?"

"Yes, it is the engine, and the most advanced aero engine should be studied! Oh! China has exhausted more than half a century of efforts and has not yet built a mature and reliable core aircraft."

" Not to say amazingly, aviation marks a country’s most sophisticated, powerful, and technologically intensive field. It can be called the modern industrial crown, and the jewel in this crown is the engine."

Hearing the words "engine", Wu Bin couldn't help thinking of Zhao Kehan. This guy went to Jinghua to learn this. I don't know if he has set his goal to this height.

At this time, Cai Guoping suddenly slapped the table, feeling a little impassioned, "Why is China's first large aircraft C919 equivalent to the Boeing 737 50 years ago!? Why is the J-20 compared to the F- 22. There is still a gap of about 10? Isn’t it constrained by the engine!"

"The fourth-generation military low-bypass ratio high-thrust turbofan engine, the fifth-generation military non-geometric structure conversion variable circulating vortex Fan engines, high-power turboshafts, turboprop engines..."

Listening to Teacher Cai telling the names of engines one after another like a few treasures, Wu Bin was a little surprised. It was the first time he knew this teacher. I also know so much about spaceflight.

"There is also an F119 engine with a fuel thrust of 156 kN! Why can the F-22 perform so many unimaginable body movements in the air? Just install two of these things!!! Let it It has become the only one fighter that can achieve supersonic cruise without afterburner. It is amazing to think about it."

"It is indeed cowhide." Wu Bin nodded.

"So I was thinking, since you want to learn more in your freshman year, then set a small goal and learn about engine subjects."

After listening, Wu Bin couldn't help but burst into light, nodded hard and asked: "At least you have to learn aerodynamics, fluid mechanics, mechanical design, right?"

"Seeing you come here to respond. Ah...I’m relieved.” Cai Guoping laughed twice, “Finally, aero engines need to work under the harsh conditions of high temperature, high pressure, high speed, and high load. They must also meet the requirements of high power, light weight, and reliability. High performance, good safety, long lifespan, low fuel consumption, low noise, and low pollution are very demanding and contradictory requirements."

Speaking of Cai Guoping, he began to break his fingers to Wu Bin, "You Look, you have to learn high temperature, aerodynamics and thermodynamics? Do you have to learn high pressure, high speed, structural mechanics? How to realize these conflicting requirements together? Mechanical design, machining, metal materials science, refrigeration, precision machining, smelting You have to learn all about casting, right? And just knowing a little bit of fur is useless, you have to learn fine."

"Hmm." At this time, there is only one Wu Bin left. Jin nodded.

PS: I will add a chapter later. In addition, the Old Brother who uploaded the character map to Pei Jiamin in the character area, show! It can be said to be pretty good.

In addition, if you have any other suitable character pictures, you can also upload them to see, thank you for your support.
