The top-notch movie queen wears books, disguises herself as a man and is handsome all over the world

Finally, when I went to the lecture theater, I saw, my dear, it turned out that everyone wanted to go together. There were so many people who came to reserve seats in advance.

The front row was gone, so the two of them quickly occupied a good seat in the middle. As soon as they sat down, Yang Qingyun took a look and said, "I'll go, there are a lot of great people here today."

The master of the computer department, the school beauty of the foreign language department, and their senior Zhen Wei, the senior who scored 98 points in the challenge paper.

Jiang Zhihan also saw it and couldn't help but gasped, "Even people from the law school came to join in the fun."

The only people they can meet are great figures from other departments, which shows how lively this open class is.

Yang Qingyun sighed: "This is not an open class. It is simply a gathering of the school's great masters."

Why do they feel so out of place in their freshman year?

Other students next to them were also discussing which department to wear grass. The flower department is not only a gathering for the masters, but also a benefit for those with good looks.

Jiang Zhihan: "It's a pity that Qin Jingyu didn't come to this grand occasion."

What kind of male god is this? Their Qin Shen can kill them instantly. After all, he is the man who caused a bloody storm on the forum on the first day he showed up at school.

Of course, Qin Shen’s two brothers, the thugs in suits, are also very good-looking.

Yang Qingyun: "It's a pity that Qin Shen was unlucky and didn't get a ticket."

As soon as they finished speaking, Principal Lu, Professor Jiang and several other professors from the physics department walked into the lecture theater. The seats in the first row were naturally reserved for Principal Lu and several other professors.

Until they saw Qin Jingyu coming in with Gu Huaiyu.

Yang Qingyun: "Am I right? That one next to Teacher Gu is God Qin?"

Jiang Zhihan was also shocked, "You read that right, who else could that face be if it wasn't Qin Shen?"

"Let me go, who is Professor Jiang's other assistant? He's so handsome!"

"You're stupid, that's not a teaching assistant, that's Qin Jingyu, a freshman in the Department of Physics. His photos are everywhere on the forum. Have you forgotten?"

"It's really Qin Jingyu. He looks even more handsome in person than in the photo."

"But, if he's not a freshman, why did he come in with the principal, professor, and the others? Isn't Professor Jiang the only teaching assistant in the school, Teacher Gu?"

"You ask me, who am I asking?"

Obviously, Yang Qingyun and Jiang Zhihan were not the only ones who were confused.

Before their first wave of shock was over, they saw that Principal Lu and Professor Zhang had reserved seats for Qin Jingyu, and seemed to be beckoning him to sit over.

Good guy, people who didn't notice Qin Jingyu at first also noticed it now.

Who is this young man that the principal and professors can take him so seriously?

Some people say that Qin Jingyu, a freshman in the Department of Physics, is also a master of learning.

Some people are confused again. Even if they have great academic masters, Zhonghai University has no shortage of them. There is no great master who can be on an equal footing with the principal and professor. No, Teacher Xiao Gu, as Professor Jiang’s only teaching assistant in the school, does not still stand. Are you here?

In addition, on the school forum at noon, someone revealed that Qin Jingyu's family background in the Imperial City was backed by the Bo Group. Could this be the reason?

But as the open class progressed, they quickly overturned this idea.

-

Qin Jingyu did not dare to sit next to the principal, so he had to find a seat next to him and sit down. He always felt that there were countless pairs of eyes staring at him from behind. Fortunately, his psychological quality was strong enough.

As Professor Jiang came on stage, the lecture hall gradually became quiet. Although he was curious about gossip, listening to the public lectures was the business.

How to merge quantum mechanics with general relativity/gravitational phenomena and maintain correctness at microscopic length scales?

This is a big unsolved problem in physics.

It is also the topic of Professor Jiang’s open class today.

Professor Jiang said on the stage: "Dear students, those who have studied physics must know that quantum mechanics and general relativity are two great theories in physics, but a basic concept is that there is a relationship between these two theories. Incompatible, in fact they are respectively targeted at two different components of the world: space-time and matter..."

In quantum mechanics, matter and fields are in a preset space-time. In this space-time, space-time itself has no physical effect on the field and is only used to describe their coordinates in time and space. This is a background-dependent theory.

General relativity is a theory that only concerns space and time, and does not involve a discussion of matter itself. It describes how matter affects the geometry of space and time, and how space and time affects the movement of matter.

The quantum gravity theory is a hypothetical theory that combines quantum mechanics and general relativity. We need to introduce the quantum gravity theory because we will be troubled by "infinity" in the calculation of quantum mechanics. Quantum force...

As Professor Jiang slowly gave in-depth lectures and demonstration videos, the students saw the beautiful space and planets, as well as the mysterious black holes in the universe.

Qin Jingyu was fascinated by what he heard and watched.

At this time, Professor Jiang switched to a four-dimensional dynamic video and continued: "Today's physics research is mainly devoted to two quantum gravity theories. String theory believes that matter is composed of one-dimensional rings. This kind of ring is defined in ten-dimensional space-time. , four of which are the four-dimensional space-time we see, and the remaining dimensions are compressed..."

Some people understand some of Professor Jiang's theories, while others have only a half-understanding, but this does not hinder his brilliance.

"I just said a lot, students, this is a diagram simulating the geometric structure of interconnected world lines, and a string perspective diagram and a ring perspective diagram in our imagination, use your imagination to combine with me Regarding the theory just mentioned, can any students stand up and answer this question, why is space fictitious and the only thing that can define our four-dimensional space-time is the world line?"

As soon as he finished speaking, all the students in the room were confused. Except for the students from the physics department who could answer the sharp questions raised by Professor Jiang, the students from other departments were almost at a loss. Professor Zhang and others were also whispering among themselves.

"Professor Jiang, this question is very tricky."

"For students, there are traps everywhere. Now it's time to test their theoretical understanding of physics and whether they can work around it."

A minute later, Professor Jiang looked at the entire classroom and asked, "Is there any student willing to get up and answer?"

No one dared to say anything or move, for fear of being called upon. Wouldn't it be embarrassing if you couldn't answer anything when you stood up?

At this time, a girl with short hair raised her hand.

Jiang Yuantao smiled happily, "That girl, which department are you in?"

Gu Huaiyu handed over the microphone at the right time.

"Hello, Professor Jiang, I am Zhen Wei, a junior in the Department of Physics."

Qin Jingyu also looked over and saw that she was a girl with a neutral appearance.

The name Zhen Wei is very familiar. Some time ago, I often heard people mention it. She seemed to be a great master in the physics department.

Jiang Yuantao raised his hand: "Classmate Zhen, what do you think of the question I just raised?"

Zhen Wei: "Professor Jiang, the black space in the picture does not contain any geometric or spatial information, and any point in it will not interact with any world lines that make up the network. This should explain why the space is fictitious. .”

Jiang Yuantao nodded slightly, "Then what if I say that the points in the blank area between the world lines have no physical meaning?"

When Zhen Wei heard this, she was stunned and pinched the phone nervously, "Because...because..."

"Sorry Professor Jiang, I can't think of an answer yet."

Jiang Yuantao: "It doesn't matter. If you can stand up and answer my first question, you are already very brave. So is there anyone else who can stand up and answer the question?"
