Chapter 204 Hello Professor
The black Audi drove into the gate of Peking University and stopped slowly in the open space in front of the office building.
The rear door opened, and two 'security' personnel with wooden faces came out first. After quickly inspecting the surrounding situation with their eyes, they then stepped aside and let Zhou Xing get out of the car.
Zhou Xing got out of the car door, and immediately saw three or four people surrounding Director Zheng, walking towards him with smiles.
"Haha, long time no see, Zhou Xing!" Director Zheng excitedly reached out to shake Zhou Xing's hand.
"Don't come close!" A security guard next to him stepped forward, stopped him, and warned loudly.
Hearing this, Director Zheng's face froze,
"It's okay, it's safe, get out of the way." Zhou Xing ordered with a smile.
Hearing the order, the security personnel moved sideways to move out of the way, but his emotionless eyes were still on Director Zheng, as long as there was something wrong with him, he would stop him.
"I'm going to trouble you again, Director Zheng!" Zhou Xing smiled sheepishly, and held Director Zheng's hand.
"Haha, you are polite, you are too polite! Aren't you still a student of Peking University? Although the situation is a bit special, Professor Li and the others are very happy to teach and solve puzzles. Especially after hearing that it is you, they are very happy." Director Zheng smiled and waved his hands again and again.
"That's right, I'm in trouble!" Zhou Xing nodded with a smile.
"Well, I specially arranged a classroom for you." Director Zheng made an inviting gesture to lead Zhou Xing the way.
Zhou Xing nodded, and followed Director Zheng's footsteps to the classroom that Director Zheng mentioned.
"Xiaoxing! Which direction are you planning to develop this time! Is it a physics problem?" Director Zheng led Zhou Xing to the classroom and asked curiously.
"Hehe, I don't plan to develop anything, so I will ask a few professors about my learning problems." Zhou Xing explained with a smile.
"Xiaoxing, I know you may be concerned about the nano-medical cabin. I never thought that things would turn out like this. The school only needs a little reputation, and I never thought of monopolizing the entire project." Director Zheng said with a look on his face. Anxiously explained to Zhou Xing.
"I know, it's all in the past. If I still care about it, I won't go back to school!" Zhou Xing shook his head with a smile.
Hearing this, Director Zheng immediately breathed a sigh of relief.
Director Zheng's eyes showed firm gaze, looked at Zhou Xing and swore: "Enen, then I won't get to the bottom of it! Xiaoxing! The door of the school will always be open for you. If you encounter any difficulties, you will try to solve them. Come here."
Zhou Xing nodded, showing a happy smile, and said with a smile: "Thank you, Director, just like what you said just now, I am still a member of the school. If I have the opportunity, I will definitely continue to win glory for the school."
Director Zheng's eyes lit up, and he was very happy. Zhou Xing's words were equivalent to admitting the "deal" between them. No matter what Zhou Xing wanted to do, Peking University could get a little credit.
Soon, Director Zheng brought Zhou Xing to a lecture hall.
The door of the classroom was open. Hearing the sound of footsteps, the four old professors with different heights and extraordinary temperament stopped the discussion and turned their heads one after another.
"This is Professor Li Jing, graduated from Columbia University: first-level subject teaching: physics, second-level subject teaching: condensed matter physics, main research direction and characteristics: magnetic nanostructure and low-dimensional physics magnetoelectronics magnetism and magnetic materials "Director Zheng introduced a tall middle-aged man in his [-]s, with a bun-shaped face and a tall figure.
"This is Professor Xu Wen, a graduate of Bielefeld University, first-level teaching: Computational Physics, second-level teaching subject: Lattice QCD, ..., main research direction: Lattice Quantum Field Theory."
"This is Professor Zhang Hua,..."
"This is Professor Chen Yuxin,..."
Director Zheng introduced four professors to Zhou Xing one after another, then looked at the four professors, introduced Zhou Xing beside him with a smile, and said, "Professors, you must all know the person next to me!"
"I know him, of course I know him! I have only heard about his name, but never seen him in person, and now I finally see him in person!"
"I didn't expect the super young genius to step into the field of physics! Welcome, we warmly welcome you."
"Haha, I've been looking forward to it day and night, and finally I'm looking forward to you!"
"Yes! Yes! Classmate Zhou, there is a way to heaven, you don't want to go, but you want to break through the door of physics. This level is not easy!"
Hearing this, the four professors looked at Zhou Xing with bright eyes, and nodded their heads in a big way.
"Professors, student Zhou Xing sends his greetings to you, and please give me your advice." Zhou Xing greeted the four professors with a smile.
"Don't be polite to give me advice! Let's discuss if there is any problem." Professor Xu Wen said with a smile.
"Yes, yes, Lao Yan and the others have publicized your deeds a lot, don't pretend to be a wolf with a big tail!" Professor Li Jing pointed it out with a smile.
"Haha! That's right, that's right! You don't need to mention the advice, otherwise you won't be able to get off the stage if you ask me, that would be too embarrassing!" Professor Chen Yuxin laughed and nodded repeatedly.
There are no men without a reputation, and Zhou Xing's name is well-known all over the world. His intelligence, knowledge, and research ability must be extraordinary. The professors looked at Zhou Xing with smiles on their faces, and they all dared not accept his greeting.
"Professor, you are too well-respected." Zhou Xing smiled, unwilling to be polite, and changed the subject: "Professor, I encountered a special problem when I was studying physics, and I would like to ask you for advice."
"Ok?"
"go ahead!"
"what is the problem?"
"what is the problem?
The four professors looked solemnly, looked at Zhou Xing one after another, and responded in unison:
"Evolutionary Mechanics: Velocity in physics is relative, and each velocity value must be relative to a specific reference object. For example, for a ship going down the river, the speed of the river relative to the bank is 3 m/s, and the relative speed of the ship is 4 m/s. The speed of the river is 7 meters per second, so the speed of the ship relative to the river bank is [-] meters per second." Zhou Xing said lightly.
"Yes, this is the basic point of view of physics." Professor Li Jing nodded.
"The speed of light is about 30 km/s, why does physics think that this speed value is relative to "any inertial system"?" Zhou Xing asked puzzled.
"This is a basic assumption of special relativity." Professor Xu Wen said with a frown.
"This basic assumption is contradictory to the concept of speed in physics. Why do you accept such an assumption?" Zhou Xing looked at the four professors and asked even more puzzled.
"No way, if you don't accept this point of view, there will be serious contradictions in physics?" Li Jing sighed and said helplessly.
"What serious conflicts will there be?" Zhou Xing asked.
"In the physics before the special theory of relativity, there must be an absolutely static frame of reference (abbreviated as the absolute static frame, absolute space or absolute static ether), but a large number of experiments cannot prove the existence of the absolute static frame, which is It is a serious contradiction." Professor Xu Wen introduced.
"The speed in physics is relative. The speed of the same object will have different speed values in different frames of reference. The speed in physics doesn't have to depend on an absolute static frame."
"Yes. However, the "acceleration" in Newtonian mechanics is absolute, and "certain velocities" in electromagnetism and electrodynamics are also absolute, and they must depend on an "absolute stationary system."
"Leaving aside the discussion of electromagnetism and electrodynamics for now, let's talk about the "acceleration" in Newtonian mechanics first. Why is the "acceleration" in Newtonian mechanics said to be absolute?"
"..."
After a while, Zhou Xing and the four professors entered the learning state of discussing the field of physics, and Director Zheng and other people who followed were stunned for a while.
