Return to the 1982 Staff Compound

Chapter 161

Chapter 161

Qiu Huoming responded to Brother Qiao's kindness to him with a smile.

He was too lazy to deal with a coward like Chang Fei, so he simply ignored him.

Qiu Huoming took out the water bottle from his bag. The water he poured in the morning was already cold. When he drank it, it was just the right temperature.

After he took a few sips of water, he felt relaxed all over. Then he stood up and did some chest expansion exercises on the spot. Chang Fei on the opposite side looked at him sternly. In this day and age, a 1-meter-tall man still had some intimidation. He looked away, thought for a moment, and wanted to say something to repair their relationship.

Qiu Huoming stretched his limbs, then sat down, casually grabbed a handful of jujubes from his backpack, and called out to Brother Qiao opposite him, "Brother Qiao, how many?"

"Hey, that's great. I've got a bird in my mouth. Let me try the taste." Brother Qiao leaned forward and grabbed three dates in his left hand.

Chang Fei immediately felt that the opportunity had come, "There are dates to eat, come, give Brother Fei some." It is not known whether Chang Fei is smart or not, but he is indeed thick-skinned. He did not care about the quarrel he had just had with Qiu Huoming and reached out to take the dates.

Qiu Huoming smiled and extended his hand forward, "Give some to Sister Xie as well."

"You are a good comrade." Brother Fei took all the dates in his hand and gave one to his wife. Comrade Xie blushed a little, gave her husband a look, and took the date.

When Qiu Huoming heard him say this, he did not refute. The car was shaking, so he simply took off his shoes, turned over and leaned against the head of the bed, took out an academic paper that Professor Li gave him from his bag and started reading.

"Qiao Lao Er, your brother? He doesn't look like that. He's much more handsome than you!"

In 1908, German philosopher Wolfsberg announced a prize of 10 marks to be awarded to the first person to prove the theorem within a hundred years after his death.

Qiu Huoming put away the documents, put on his sandals, yawned, tidied his backpack, and turned to look out the window.

"Hi, my last name is Qiao, and I'm the second child. This is just a nickname. Don't listen to her nonsense. My full name is Qiao Dashan."

"Eat?"

Qiu Huoming touched his nose and said, "I guessed it. Your name is so magnificent, your brother can't be bad. Only the sea can match the mountain."

"Thank you, Brother Qiao." Qiu Huoming finished his soda with a smile and followed Qiao Laoer back.

After a while, the flight attendant shouted, "It's time to leave. Get on the bus! Get on the bus!"

Qiu Huoming drank the soda he got for free and listened to Qiao Laoer bragging across the way.

"Okay, then I'll follow you." Qiu Huoming raised the corner of his mouth.

Although Qiao Laoer was a boaster, he also knew a lot. He had been riding this train line for quite some time and was familiar with some of the popular goods in the south.

(Hard Sleeper Style 2)

If the verification of this hypothesis is published in Science magazine, he will gain both fame and fortune, and at the same time he will be able to contribute to some scientific research in China.

"Hey, we're here. Xiaoqiu, would you like a bottle of soda?" Qiu Huoming was brought back to reality by Brother Qiao's shout.

Although the supply and marketing cooperatives sell it, you may not be able to buy it even if you have money; you need an order.

You will understand if you think about it carefully.

This is one of the three most difficult conjectures in the world, and it is also a conjecture that has never been solved.

"That's enough. Let's buy some pastries." Brother Qiao grabbed Qiu Huoming and walked quickly towards a metal cart.

Passing the counter, she ordered two bottles of soda for Qiao Laoer.

A flight attendant at the door said, "Three minutes, don't waste time."

While the other party was taking a break and drinking soda, Qiu Huoming asked, "Brother Qiao, are you really called Qiao Lao Er?"

The boy on the middle bunk had gotten out of bed at some point and was talking to a middle-aged woman. After a while, the two of them walked out to the aisle.

"Brother Qiao, where did you buy this bag? It looks nice." Qiu Huoming asked after getting closer.

Qiu Huoming paid the money, took the oil-paper bag and waited for Brother Qiao to buy the food, then turned and walked towards the car door.

The tea eggs were even cooked with salt and soy sauce. After eating, Qiu Huoming drank several sips of water to get rid of the salty taste.

Qiu Huoming walked over and called out, "Hello, Sister Qin."

Brother Qiao stared at the staff member, suddenly slapped his thigh, and walked over quickly.

Qiu Huoming retracted his gaze, took out the meat bun and started eating. After taking a bite, he found that the taste was much better than he had imagined.

"Delicious." Qiu Huoming praised, saying that the meat buns had large fillings and chewy dough.

As for the "Goldbach Conjecture", it is almost known to everyone. It is two conjectures about the relationship between positive integers and prime numbers. It is stated as follows: (A) Every even number not less than 6 is the sum of 2 odd prime numbers; (B) Every odd number not less than 9 is the sum of odd prime numbers.

The cart was late, and Brother Qiao had to go buy cigarettes and couldn't wait any longer, so Qiu Huoming followed it because he wanted to see what a train dining car looked like in this era.

As the two were chatting and laughing, the car slowly stopped. The people standing in the car staggered in unison. The car then officially stopped and the door slowly opened.

"No, it's work time. Wait a moment. I'm busy right now. I'll get you two bottles first..."

At this moment, several groups of people arrived and the seats that had just been vacant were filled up again.

More than an hour has passed.

"What you shouldn't be interested in is just a mathematical document." Qiu Huoming closed the document, rubbed his eyes, and glanced at his watch.

The door closed and the train body shook. Qiu Huoming shook a bit as the train started moving. The train slowly moved forward and gradually accelerated. With the sound of "clang clang clang", the snack stand on the platform gradually moved away...

"How do you know?" Qiao Laoer was stunned.

"Hey, they went to the dining car to eat. There are so many people at this time, there is no need to squeeze through." Brother Qiao smiled and said, "Listen to me, I often take this route..."

This is an important window for China to open up to the world and it cannot be ignored at this moment.

The two men staggered towards the dining car.

Qin Xiaohong worked very efficiently. She pushed the cart, put the dirty dishes on it, and walked towards the kitchen.

There were three empty tables in the restaurant, and a young female staff member was bending over to clean the tables.

As a good partner of instant noodles, ham sausage was not officially introduced in China until 87, which marked the beginning of the era of instant noodles with ham sausage...

This situation continued until 87, when the grain and oil relations were liberalized. The situation began to improve, and a large number of manufacturers, upon hearing the news, began to switch to the instant noodle business, which lowered the price of instant noodles, making it a convenient food that everyone could afford.

"Have you finished your meal?" Qiu Huoming asked.

In addition, this paper is followed by a reportage entitled "Goldbach's Conjecture" published in 1978 by the writer Xu Chi, with Chen Jingrun as the protagonist.

He raised his hand and showed Qiu Huoming his wrist. "This is called an electronic watch. People in small towns generally don't recognize this thing. This is much better than a mechanical watch. It can tell the time very clearly without having to adjust it every day..."

While I was thinking, I saw the car slowing down and there were more buildings on both sides.

"We're done eating. There aren't many people over there right now. Let's go."

"Okay, let's go together."

As soon as he finished speaking, he turned around and walked quickly to the rear of the car.

In fact, there is a very important place in Yangcheng, the city where he will study in the future, which is the "Canton Fair".

Suddenly the crowd became chaotic, and some people who had not bought anything turned around and ran back without waiting.

Qiu Huoming discovered that any information he had seen or read in his previous life would gradually become clear to him as long as he recalled it carefully.

"I was just assigned to this section and just got on the bus. Hey, please sit down. Do you want to order food?" Qin Xiaohong asked.

"Okay, I'll treat you. I'll go back first and come back in the evening." Qiao Laoer's face was full of smiles.

Before he got close, Qiu Huoming smelled the fragrant aroma of tea eggs.

It was like he just recalled the scene when the professor on the stage explained the paper published by Andrew to the students word by word. The content of the paper was imprinted in his mind more and more clearly as he recalled it.

Seeing that the crowd was gathering, Qiu Huoming immediately moved his backpack closer to his chest. A man who was following him suddenly stopped, snorted, and left behind him.

Qiu Huoming asked for two meat buns and two tea eggs, which the uncle put all in the same oil-paper bag and stuffed them into his hands.

Brother Fei and Sister Xie were gone. He glanced around but saw no one.

'Fermat's conjecture' is Fermat's Last Theorem, also known as "Fermat's Last Theorem", proposed by French mathematician Fermat. It asserts that when the integer n>2, the equation x^n+y^n=z^n about x, y, z has no positive integer solution.

As the exchanges between Shenzhen and Hong Kong became closer, some small assembly factories appeared in Shenzhen, and the electronic watches produced here became cheaper.

"Brother Qiao, is your brother called Qiao Dahai?"

"Brother Qiao, are you and Sister Qin classmates or neighbors?" Qiu Huoming asked curiously.

There are passengers in front who have finished their meal and are walking back. The junction between carriages is usually the dirtiest and has a strange smell.

"Oh, yes, Xiaoqiu, come here. You want a soda, right? I'll have one too. It's my treat."

While he was thinking, he suddenly heard Brother Qiao asking him, "Xiao Qiu, what are you looking at?"

There is no ban on smoking on the green-skinned train, so people getting off the train do not rush off just to have a smoke like in later generations.

Brother Qiao smiled and said, "I bought it in Shenzhen. It's very sturdy."

It is now 1982. I wonder if I can still get the bonus? Qiu Huoming searched for the content of the open class he saw in college.

Qin Xiaohong is still in the kitchen and hasn't come out yet.

The price of instant noodles at this time is comparable to that of Moutai. There are very few manufacturers making instant noodles. As far as he knows, probably only some manufacturers in Capital and Shenhai can make them at this time.

He turned his head and watched Qin Xiaohong return to the kitchen, then he stood up with high spirits, "Xiao Qiu, come with me for dinner tonight, it's my treat."

After a while, Brother Qiao came over from the back of the car, swinging his hands, and returned to the bed. He wiped his wet hands on his pants a few times and said, "Let's go. The car is about to stop..."

Almost all the passengers here get off the train to buy snacks. Qiu Huoming and Brother Qiao returned to the carriage one after the other. The two of them took their food and sat on the folding chairs in the aisle, watching the lively scene on the platform.

"Why didn't I meet you when I came here for dinner last time?" Brother Qiao asked back.

Conjecture (A) is called the Goldbach conjecture about even numbers; conjecture (B) is called the Goldbach conjecture about odd numbers. Proving the correctness of (A) can lead to the conclusion that (B) is also correct.

When Qiu Huoming came to his senses, Brother Qiao had already gotten out of bed and was looking at the information in his hand.

The blueprint for the future gradually took shape in his mind.

There were already several people gathered at the door. This was a hard sleeper, and the environment was much better than that of the hard seat. When Qiu Huoming walked over, he took a few glances and saw that the door of the hard seat was full of people. These were the people who had not bought seats.

"You're a good person, you listen to advice." Brother Qiao raised his wrist, glanced at the electronic watch on his wrist and said, "Oh, there are still a few minutes before the station arrives. I'll go get some water first and come find you later."

As a reborn person, he has innate advantages. He is insignificant now, but as long as he excels in a certain field, he can use these to succeed in the future.

Qiu Huoming stood up, put on his backpack, and followed him to the door.

Brother Qiao had a nylon shoulder bag on his waist, which looked quite high-end.

Qiu Huoming flipped through the information in his hand for a long time, and then his thoughts flew to the second of the three major conjectures, 'Fermat's conjecture'.

Qiu Huoming was in the carriage and did not see the scene of people gathering together to wait for hot water and make instant noodles like in later generations.

This is a copy of the paper published by Chen Jingrun in 1973 on the "Goldbach Conjecture". Professor Li probably wanted to cultivate Qiu Huoming's love for mathematics.

Qin Xiaohong turned her head and looked over when she heard this, then a smile appeared on the corner of her mouth, "Qiao Laoer, why is it you?"

The dining car was in the middle of the train. Along the way, we met Chang Fei and Sister Xie who were returning. Probably because he was full, Chang Fei smiled more often and greeted Qiu Huoming for the first time.

"His name is Xiaoqiu, a friend I just met. Hongying, give me three bottles of orange-flavored soda. I'll treat you..."

While he was thinking, Qin Xiaohong came out and walked to Qiao Laoer's side. "It's too busy now. I can't spare the time. I will switch shifts with my colleagues tonight and bring your friends with me. I will treat you to a meal in the dining car..."

"Both. We came from the same alley. I went to a technical school and she also went to a technical school... I haven't seen her in several years. How come she ended up here?" Qiao Laoer muttered.

At that time, electronic watches were all imported products, only available in coastal cities, and most of them were smuggled in from port cities.

The routine life was not suitable for him.

"Qin Xiaohong!" he shouted as he moved closer.

"Xiao Qiu, the next station will stop for several minutes. Let's go to the platform to buy some food. I'm tired of the food on this train. It's expensive and not tasty." Brother Qiao was quite familiar. He walked from the bed to the aisle, stretched, and suggested casually.

"I, Qiao Lao Er, have friends all over the world, and I can get along well wherever I go..."

He remembered that Fermat's conjecture had been solved. Between 1993 and 1995, British mathematician Andrew Wiles published a paper that finally proved the validity of the conjecture.

As Qiu Huoming walked through the area, he thought of countless ways to make a fortune. In an age of material scarcity, there were indeed business opportunities everywhere.

Four people passed each other.

Upon hearing this, Qiao Laoer nodded and said, "That makes sense." As he spoke, he turned his head absentmindedly and looked towards the counter.

After dinner, Qiu Huoming followed Brother Qiao towards the dining car.

Just talking about the current university education, he may know more than some of the current teachers. For him, reading is a necessary process that allows him to publish his research results naturally without being abrupt.

It's like I just reviewed it.

The uncle pushing the cart greeted them immediately when he saw them coming.

For Qiu Huoming, these are all first-hand information. Qin Xiaohong is an internal employee of the railway, and he might be able to ask her for help in buying tickets in the future.

As for Qiao Lao Er, this man is a trader who sells all branded goods and is a walking database.

There is one more chapter, and I am working hard...
