Xueba's Sea of ​​Stars

Chapter 133 Tiananmen Square

Through several chats with Wu Bin, Song Nanfeng knew how deeply he was poisoned physically, so he also understood how attractive pure physics is to the kid.

Luo Wenmin originally planned to explain that Peking University's physics is also very pure, but the afternoon class has already started, and Wu Bin had no choice but to leave reluctantly.

The two professors were left blowing their beards and staring at each other.

……

By the time of No. 15 days, the real questions of the previous Asian competitions and the real questions of the world competition have also been analyzed.

Ever since, the teachers began to show their talents.

Professor Zheng Kaiqi from Nantah University first told the students that "competitions generally do not use the four major mechanics." Then he began to teach the students quantum mechanics.

After a Hamilton-Jacobi equation, Lagrangian, Schrödinger's wave mechanics, Heisenberg's matrix mechanics, and Feynmander path integrals, there is another fancy formula calculation on the blackboard.

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, the stories of the competitions in previous years, such as the equation he clearly mentioned 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 patted the podium directly, and looked down angrily and roared.

"Which one of you is selected into the national team this year, if you make a mistake in the questions I mentioned, let me tell you, as long as you enter Peking University, I promise to make you comfortable!"

"Why should we take the blame for those people from last year..." This is the voice of most people after hearing it.

After yelling, Luo Wenmin began to talk about the talented Jamaican boy who won the first place a few years ago. He was only 16 years old, that is, the first year of high school. He described in detail the special skills and postures he had when doing the experimental questions. It can be said to be 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 activated...

The reason is that a large number of news channels once accused that the collision experiment may produce black holes and destroy the earth.

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

Regarding this story, Lu Zhi sighed: "It has to be said that both domestic and foreign media like to spread their ignorance and ignorance."

"Coach, that's called bringing your own wisdom-reducing halo." Zhang Fu raised his hand to speak.

Lu Zhi shook his hand, "One meaning."

Then Lu Zhi spent 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 he was still a little confused about the computer-simulated beam diagram.

"So, the limit energy of the collider is actually not very high. There are too many particles of this energy level in cosmic rays. Cosmic ray particles with 100 times higher energy than this energy often hit the earth. They all hit 46 For hundreds of millions of years, no black hole has been created to suck the earth in, it's just nonsense."

Wu Bin originally thought that this powerful rant was the end, but unexpectedly, Lu Zhi sighed again after cleaning the blackboard.

"Hey, a rotten capitalist country spent billions of dollars to make a big toy that is probably useless. It's extravagant."

From Lu Zhi's tone, Wu Bin seems to have heard a little bit of sourness, but he still wants to complain, as a physicist, is it really okay to say this...

Moreover, Lu Zhi's words made Wu Bin think about how accurate his statement "the current particle collider's performance does not match its cost and the thought it took"...

And even if the collider has not yet exerted the effect of allowing human beings to make new breakthroughs, Wu Bin does not want to say that it is a "big toy" built at a cost of billions of dollars, but that it is a human being spent A physical dream woven with billions of dollars.

Before leaving, Lu Zhi left a thinking question on the blackboard, asking p-type and n-type semiconductors are actually electron movement, showing that the carriers are holes or electrons, so why do they behave differently under the Hall effect? Negative potential difference?

The cited students all 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 will come up with today.

"The weather is fine today, let's go visit Tiananmen Square."

"???"

Listening to Coach Lu's casual tone, there was a face of question marks underneath.

"It's a combination of work and rest. I've been studying for two weeks. Go out today to get some fresh air."

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

Just kidding, after more than two weeks of study, he has accumulated a lot of interesting questions that have not been solved. In addition, he hasn't had time to read the few sets of books sent by the teacher.

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

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

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

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

"Of course!" The people around Wu Bin suddenly became violent.

"Wow...why are you so excited, you guys." Wu Bin was taken aback.

"Hey, do you know that you put a lot of pressure on us as the number one in the final?"

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

"I'm doing rigid body mechanics in my dreams now, can you feel my pressure!"

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

"Hey, Zou Ping, I'm digressing, you."

……

Wu Bin, who was suddenly criticized by the crowd, was puzzled, "I just like reading books, what's wrong?"

"..."

"Damn! Catch him! Take him out to beat the horns!"

"What is the horn?"

"It's just hitting a tree, don't you guys play with that?"

"Oh, tear it up! You want it."

"We are called pole people."

"We call it piling."

……

Taking advantage of a group of people discussing the various nicknames of Aruba, Wu Bin quickly fled the scene. After all, everyone is familiar with each other now, and Wu Bin believes that they are definitely not just talking.

……

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

In fact, Wu Bin is still looking forward to this capital center, after all, he was not influenced by his grandfather when he was a child.

I often told him, "It was an honor to go to Tiananmen once in the 60s."

"Taking a photo under the chairman's photo can last a lifetime."

"Looking at the flag-raising ceremony, how surging the heart will be" and so on...

Although Wu Bin has seen Tiananmen Square countless times in the photos, but now that he is actually standing in front of Tiananmen Square, Wu Bin really feels his heart beating faster, and many red classic stories that his grandfather once told him can't help but spring up in his heart , and a sentence his grandfather often chanted about him when he was a child.

"As a human being, no matter how promising you are, you must not forget your roots. Your roots are here, remember?"

PS: The second update, there should be no problem with the third update today, is it okay to ask for a monthly pass?
