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

Luo Wenmin originally planned to explain that the physics of Peking University is also very pure, but the afternoon class has already begun, and Wu Bin has to reluctantly leave.

Leaving the two professors blowing their beards and glaring at each other.

……

By the fifteenth day, the past Asian and World competitions had been analyzed.

As a result, the teachers began to show their talents.

Professor Zheng Kaiqi of NTU first said to the students: "The four major mechanics are generally not used in competitions. "Then I started teaching quantum mechanics to my classmates.

A Hamiltonian-Jacobian equation, a Lagrangian quantity, Schrödinger's wave dynamics, Heisenberg's matrix mechanics, Feynmand's path integrals are followed by a blackboard formula with bells and whistles.

Although Wu Bin, who was sitting below, didn't understand some of them very well, he still enjoyed listening to them.

Professor Luo Wenmin, who teaches magnetism, began to tell stories...... Well, the story of the competition in previous years, for example, the equation he talked about last year, but none of the five people who went to the competition wrote it correctly, and he slapped the podium excitedly, and looked down with an angry face and roared.

"Which of you is selected for the national team this year, if you do the wrong question I said, tell you, as long as you enter Peking University, I promise to make you comfortable!"

'Why are we taking the blame for last year's gang...... is what most people think after listening to it.

After yelling, Luo Wenmin began to talk about the Jamaican genius boy who won the first place a few years ago, only 16 years old, that is, a freshman in high school, and carefully described what special skills and postures he had when doing experimental problems, which can be said to be quite legendary.

The things introduced by the head coach Lu Zhi are relatively high-end, the particle collider.

It begins with a short story about an Indian girl who committed suicide by drinking pesticides when she heard that the particle collider had been successfully activated......

The reason is that there used to be a large number of news channels accusing the collision experiment of potentially creating a black hole that could destroy the planet.

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

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

"Coach, that's called bringing your own aura of reducing intelligence." Zhang Fu raised his hand to speak.

Lu Zhi shook his hand, "One meaning." ”

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

Wu Bin understood a rough idea, and was still a little confused about the beam diagram simulated by the computer.

"Therefore, the ultimate energy of the collider is actually not very high, there are too many particles of this energy level in cosmic rays, and cosmic ray particles that are 100 times higher than this energy often hit the earth, which has been hitting the earth for 4.6 billion years, and there is no black hole to suck the earth in, pure nonsense."

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

"Alas, the rotten capitalist countries have spent billions of dollars to build big toys that are probably useless, and they are extravagant."

From Lu Zhi's tone, Wu Bin seemed to hear a little sourness, but he still wanted to complain about whether it was really good for him to say this as a physicist......

Moreover, Lu Zhi's sentence made Wu Bin correct to his statement that "the current particle collider effect does not match its cost and cost......

And even if the collider really hasn't played a role that can make new breakthroughs for mankind, Wu Bin doesn't want to say that it is a "big toy" that has been built with billions of dollars, but that it is a physical dream woven by mankind with billions of dollars.

Before leaving, Lu Zhi left a question for thinking on Tim, asking why p-type and n-type semiconductors actually move electrons, showing that carriers are holes or electrons, so why do they exhibit different positive and negative potential differences under the Hall effect?

All the students stayed in the study room to start discussions.

When I woke up, the students came to the classroom early again, thinking about what new tricks the teacher would come up with today.

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

“？？？”

Listening to the casual tone of Mr. Lu's head, there was a question mark face underneath.

"Combining work and rest, I've been studying for two weeks, and I'm going out to breathe today."

"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, and he has not had time to turn through the several sets of books sent by the teacher.

"No, we have to go." After Lu Zhi finished speaking, he 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 one sentence: "Gather at the front door in half an hour." ”

"Ouch, Wu Shen, you've been targeted." Li Yan patted Wu Bin's shoulder and laughed.

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

"Absolutely!" The people around Wu Bin suddenly burst out.

"Wow...... Why are you so excited? Wu Bin was taken aback.

"Gan, do you know that you are still working so hard as the first in the finals, and you have a lot of pressure on us?"

"It's just, I'm embarrassed to take out my phone, okay?"

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

"That's it, do you know how good-looking the big sister is, I ...... it"

"Hey, Zou Ping, you're off topic."

……

Wu Bin, who was suddenly attacked by everyone, looked inexplicable, "I just like to see what's wrong with books." ”

“……”

"Oh yes! Get him! Lift it out and beat the horns! ”

"What's the horn?"

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

"Oh, rip your cheeks! You have to get it. ”

"We're called pole people."

"We call it piling."

……

While a group of people were discussing various aliases for Aruba, Wu Bin quickly fled the scene, after all, now that everyone is familiar with each other, Wu Bin believes that they are definitely more than just talking.

……

As one of the capital's most famous attractions, Tiananmen Square is still crowded even on weekdays.

In fact, Wu Bin is still very longing for this capital center, after all, he was not influenced by his grandfather when he was a child.

I often tell him, "How honorable it was to go to Tiananmen Square once in the 60s." ”

"Taking a picture under the chairman's photo can blow for a lifetime."

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

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

"Be a man, no matter how good you are, you can't forget your roots, your roots are here, remember?"

PS: The second watch, there should be no problem with the third watch today, it's still okay to ask for a monthly pass, right?
