Chapter 28 Fang Da cheated

With Bai Ping now confident, she went on a big shopping spree in Fengyuan, buying bags after bags of various local specialties. Everyone in the family had gifts - now that she had more money, she felt different.

Fang Ya also successfully obtained three sleeper berth tickets. As for Fang Mingyuan, it would be no problem to squeeze in with any of the three - he was too young to buy tickets. Bai Ping sent an email to the capital in advance

A telegram was sent to the capital to inform more people to pick up the train. With the help of Fang Ya and his two co-workers, Fang Mingyuan's family of four boarded the train bound for the capital at noon on the third day after arriving in Fengyuan.

Although the train of 1984 was bound for the capital, there was still a huge gap compared with the direct trains of later generations. In the green carriage, which looked a bit old, there was no air conditioning and only a few broken fans. Fortunately,

It's winter now, and people are crowded in the carriage. They don't feel cold, but the air is a bit turbid. The three tickets the Fang family got are not together, and only one of them is for the lower berth, but Fang Mingyuan came out.

, invincible, who can be shameless in front of everyone and refuse a child's plea for the elderly? So it didn't take much time, and the three tickets were exchanged together, and there were two lower berths among them. Naturally, grandma Fang Mingyuan

Another show of love.

After a long wait, the train finally started. However, the maximum speed of the train was only forty or fifty kilometers per hour, which was really a torture for Fang Mingyuan, who was used to the train speed of two hundred or three hundred kilometers per hour in later generations. After a while, Fang Mingyuan

I am tired of the scenery outside the window. "Grandpa, play chess, play chess, this train is as slow as a turtle crawling!"

"Mingyuan, don't talk nonsense, you think this train is too slow!" Bai Ping laughed and scolded, "What about the people who take the slow train that stops at every stop?"

So Mr. Fang took out the chess set from his luggage bag and laid it out on the bed. Ever since the game of chess between Fang Mingyuan and Mr. Zhao Jianguo, Mr. Fang had a little chess friend. Whenever Fang Mingyuan had nothing to do,

, Mr. Fang will pull him to play a few games. There will be wins and losses, and the fun is endless.

As time went by, the increasingly bored people in the sleeping berths around them slowly noticed the old man and the young man playing chess. There were people who knew chess and were good at chess, watching the game. Originally, they thought it was just a game.

The old man was teaching the children to play chess, but after a few glances, they were surprised to find that Fang Mingyuan really knew how to play chess, and he seemed to be very good at it! This time, he attracted even more attention from these people. Wait.

By the end of the game, these people were certain that this child, who looked to be under ten years old, was quite accomplished in chess.

Fang Mingyuan and Mr. Fang played three games, and in the end Mr. Fang won with difficulty 2 to 1. In fact, Fang Mingyuan was secretly playing tricks on him. After all, this was not at home. He had to protect the face of the old man, otherwise he would lose to his grandson.

In front of so many outsiders, the old man was so embarrassed.

After playing three sets, Fang Mingyuan complained that he was tired, and someone took the initiative to take his place. Fang Mingyuan lay on his grandma's berth, looking at the scenery slowly passing by outside the window, and after a while he couldn't help but sigh again. "Okay.

Wait, how long will it take before we can reach the capital?"

"Kids, it's more than a thousand kilometers from Fengyuan to the capital. Such a long distance will of course take a longer time." A middle-aged man sat up from the middle bunk, stuck his head out and replied with a smile.

"It's only over a thousand kilometers, and it takes at least twenty-four hours to walk. Isn't that slow?" Fang Mingyuan asked loudly.

"Then you can only take a plane, but it's not so easy to buy air tickets in our country now. And the air tickets are too expensive!" The middle-aged man shook his head. He could see that Fang Mingyuan's family was wearing

His appearance and temperament suggest that he is not a citizen of a big city. For them, the air fare is obviously too high.

"Yes, we can't afford to fly." Fang Mingyuan said with some frustration. Not to mention now, even in the previous life, airplanes became a means of travel for ordinary people, and that was about two thousand years ago. But now, I'm afraid, in addition to

Except for those who have to grit their teeth to buy tickets when state workers go out on public funds or have urgent matters at home, ordinary people are definitely not able to fly. Although the Fang family has a little more money now, money is not wasted like this.

.

"It would be great if there was a maglev train!" Fang Mingyuan muttered. In later generations, he took the Shanghai maglev train and also took the "Harmony", which can be said to be a profound memory. Compared with them, the current speed can only be called

It's so slow.

"Magnetic levitation train? What kind of car is that?" The middle-aged man in the middle berth had a very good ear. Although Fang Mingyuan muttered in a low voice, he actually heard it.

Fang Mingyuan was startled. He didn't expect that he would be heard by anyone. But then he thought about it. He was just idle. The theory of magnetic levitation seemed to have been proposed in Europe at the beginning of the century. It was no big deal for him to talk nonsense now.

"Uncle, the maglev train is a high-speed train." Fang Mingyuan has always been sweet-tongued. Anyway, given his age, he doesn't suffer from being sweet-tongued.

"High-speed train? How come I haven't heard of it? How fast?" the middle-aged man asked in surprise. He would be damned if he had heard of it, even if he is at the forefront of this technology

Britain and Germany have not built experimental lines so far. China? I am afraid that only those train experts who have studied abroad may have heard of it.

Fang Mingyuan scratched his head. The theoretical speed of the maglev train can reach more than 500 kilometers per hour, and the actual speed can also reach more than 300 kilometers per hour. But if he told the truth, these data would be hard to find now. "At least hundreds of kilometers per hour.

Hours. This is just a train I imagined."

The middle-aged man was relieved. It turned out to be just a child's fantasy. But looking at Fang Mingyuan's serious look, he couldn't help but ask: "Then can you tell me what kind of train this is and why it can run?"

How fast?" The journey is boring anyway, so teasing the children can kill time.

"Uncle, have you ever played with magnets?" Fang Mingyuan asked.

"Of course, my uncle had several big magnets when he was a kid!" the middle-aged man said with a smile. When they were kids, having a few big magnets in their hands was definitely something to be proud of.

"Then uncle should know the principle of same-sex magnets repelling each other and opposite-sex magnets attracting each other. This is what I imagine. If you turn the rail into a magnet and the train into another magnet, and use the principle of same-sex repulsion, as long as the magnetic force is enough,

is large, then the train should be able to

The train floats on the track. If we can control the strength of this magnetic force to ensure that the train will not roll over and move sideways, and can be stable above the rails and move in the direction of the rails, then this is a maglev train. The teacher said

Passed, the reason why the train

The ability to move forward depends on the friction between the wheels and the rails. The reason why airplanes fly fast is because they only have air resistance, but trains not only have air resistance, but also ground resistance, so they cannot go fast.

.If it’s a maglev train

Because it floats on the rails, which means it also has no ground resistance, the speed is naturally faster!" Fang Mingyuan tried his best to explain the principle of magnetic levitation in the tone of a child, and he also wanted to make it clear,

This really cost him a lot of thought.

For a long time, there was no reply from the middle-aged man. Fang Mingyuan stuck his head out and looked up strangely. He saw the middle-aged man sitting there dumbfounded, like a wood carving and clay sculpture!

"Oops, the scammers are out!"
