Chapter 133 Tiananmen

Through several chats with Wu Bin, Song Nanfeng already knew how deeply he was addicted to physics, so he also understood how attractive pure physics was to the boy.

Luo Wenmin originally planned to explain that Peking University's physics was also very pure, but the afternoon class had already begun, and Wu Bin had to reluctantly leave.

The two professors were left staring at each other.

…

By the fifteenth day, all the real questions from previous Asian competitions and world competitions have been analyzed.

Ever since, all the teachers began to show their special abilities.

Professor Zheng Kaiqi from NTU first told the students, "The four major mechanics are generally not used in competitions." Then he began to teach the students quantum mechanics.

A series of Hamilton-Jacobian equations, Lagrangians, Schrödinger's wave mechanics, Heisenberg's matrix mechanics, and Feynmander path integrals are followed by a blackboard calculation with fancy formulas.

Although Wu Bin, who was sitting below, didn't quite understand some parts, he still enjoyed listening to it.

Professor Luo Wenmin, who teaches magnetism, started to tell stories... well, stories about competitions in previous years. For example, he clearly talked about the equation last year, but none of the five people who participated in the competition wrote it correctly. He was so excited when he told it. He took a picture of the podium and looked down with an angry look on his face.

"If any of you selected for the national team this year gets the questions I asked you wrong, I'll tell you, as long as you get into Peking University, I promise to make you feel comfortable!"

‘Why should we take the blame for last year’s group of people...’ This is what most people think after hearing this.

After yelling, Luo Wenmin started talking about the genius boy from Jamaica who won first place a few years ago. He was only 16 years old, that is, a freshman in high school. He carefully described his special skills and postures when doing experimental questions. It can be said that he is quite legendary.

The thing introduced by the head coach Lu Zhi is relatively high-end, a particle collider.

At the beginning, I told a short story about an Indian girl who committed suicide by drinking pesticide when she heard that the particle collider was successfully started...

The reason is that a large number of news channels once accused the collision experiment of possibly producing a black hole and destroying the earth.

This girl was afraid of the end of the world, so she went there first...

Regarding this story, Lu Zhi sighed: "I have to say that domestic and foreign media like to spread their ignorance and ignorance."

"Coach, that's called having a halo of wisdom." Zhang Fu raised his hand to speak.

Lu Zhi waved his hand and said, "Just the same idea."

Lu Zhi spent the next three hours drawing pictures, formulating formulas, and using PPT to explain to Wu Bin and others how the particle collider ensures that two particles collide together.

Wu Bin understood the general idea, but was still a little confused about the computer-simulated beam diagram.

"So, the ultimate energy of the collider is actually not very high. There are too many particles of this energy level in cosmic rays. Cosmic ray particles 100 times higher than this energy also often hit the earth, which have hit 46 It has been hundreds of millions of years, and no black hole has been created to suck the earth into it. It’s all nonsense.”

Wu Bin originally thought that this powerful complaint was the end, but he didn't expect that Lu Zhi would sigh again after wiping the blackboard.

"Oh, rotten capitalist countries spent billions of dollars to build a big toy that is probably useless. What a luxury."

From Lu Zhi's tone, Wu Bin seemed to hear a bit of sourness, but he still wanted to complain, is it really okay for a physicist to say this...

Moreover, Lu Zhi’s words made Wu Bin tell him how correct he was that “the current particle collider’s performance cannot match its cost and effort”...

And even if the collider really hasn't produced the effect of allowing humans to make new breakthroughs, Wu Bin doesn't want to say that it is a "big toy" that cost billions of dollars to build, but that it is a "big toy" that humans spent billions of dollars to build. A physical dream woven with billions of dollars.

Before leaving, Lu Zhi left a question on the blackboard, asking why p-type and n-type semiconductors actually move electrons and show carriers as holes or electrons, so why do they show different positive behavior under the Hall effect? Negative potential difference?

All the students who were invited stayed in the study room to discuss.

After waking up, the students came to the classroom early together, thinking about what new tricks the teacher would come up with today.

"The weather is very nice today. Let's go visit Tiananmen."

"???"

Listening to Coach Lu's casual tone, there was a question mark on his face.

"It's about combining work and rest. I've been studying for two weeks. Let's go out and get some fresh air today."

"Coach Lu, can I choose not to go..." Wu Bin weakly raised his hand.

Just kidding, after more than two weeks of studying, he still accumulated a lot of interesting questions that he had not yet solved. In addition, he didn't have time to read the several sets of books the teacher handed out.

"No, everyone has to go." After speaking, Lu Zhi pointed at Wu Bin, "Especially you, you are not allowed to bring books."

Then, without waiting for Wu Bin to refute, Lu Zhi turned around and left, leaving only the words "Meet at the front door in half an hour."

"Ouch, Wu Shen, you are being targeted." Li Yan patted Wu Bin on the shoulder and laughed.

"Is it wrong to love studying..." Wu Bin looked depressed.

"Of course!" The people in the circle around Wu Bin suddenly burst into laughter.

"Wow... why are you so excited?" Wu Bin was startled.

"Gan, do you know that you are putting a lot of pressure on us as the number one in the finals and still fighting so hard?"

"That's right, I'm too embarrassed to take out my phone, okay?"

"I'm dreaming about rigid body mechanics right now, can you feel my pressure!"

"That's right, do you know how beautiful Miss Bei is? I even..."

"Hey, Zouping, you're off topic."

…

Wu Bin, who was suddenly criticized by everyone, looked confused and said, "I just like to read books. What's wrong?"

"..."

"Yeah! Catch him! Take him out to fight!"

"What is the horn?"

"It's just hitting a tree. Don't you want to play?"

"Oh, tear the body! You must have it."

"We are called Ganer people."

"We call this piling."

…

While a group of people were discussing various nicknames for Aruba, Wu Bin quickly fled the scene. After all, everyone was now familiar with each other, and Wu Bin believed that they were definitely more than just talking.

…

As one of the most famous attractions in the capital, Tiananmen is still crowded with people even on weekdays.

In fact, Wu Bin still admires this capital center very much. After all, he was not influenced by his grandfather when he was a child.

I often told him, "It was so glorious to be able to go to Tiananmen in the 1960s."

"Taking a photo in front of the chairman can last a lifetime."

"Just take a look at the flag-raising ceremony and you will feel so excited" etc...

Although Wu Bin has seen Tiananmen countless times in the photos, but now standing in front of Tiananmen, Wu Bin really feels that his heartbeat is a little faster, and many red classic stories that his grandfather once told him can't help but emerge in his heart. , and a sentence his grandfather often mentioned to him when he was a child.

"As a human being, no matter how successful you are, you must never forget your roots. Your roots are here, remember?"

PS: The second update, and the third update today should be fine. Is it okay to ask for a monthly ticket?
