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

Qin Jingyu knew at a glance that Principal Lu was probably happy and a little drunk, so he had no choice but to stand up and said, "Principal Lu is too polite, so I can only have tea instead of wine."

Lu Beichang waved his hand: "It's okay, it's okay, I can drink it, you can do whatever you want."

The two of them clinked glasses in the air, but Zhang Liangan and others looked on in a daze.

Good guy, it was just suspicion at first, but now it's over. Principal Lu personally toasted a "student". If they still can't react, they will drink and be stupid.

It is absolutely certain that Qin Jingyu is the youngest mathematician in their country.

Unexpectedly, the little mathematician who was hotly discussed by the people all over the country suddenly turned into their student. They didn't even notice it in the past few months. Who can not be shocked by this? ?

Seeing that Zhang Liangan wanted to imitate Principal Lu and get up to toast, Jiang Yuantao spoke up, "Old Zhang, you don't have to get up, you should just sit down. Jingyu came to Zhonghai University to study. His original intention was to keep a low profile. Just pretend you don't know." His identity has improved."

This is to make the identity matter clear. Zhang Liangan also asked in shock: "Professor Jiang, is he really that little mathematician from China?"

Jiang Yuantao nodded, "As long as you know this, there is no need to tell anyone."

After finishing his words, Qin Jingyu stood up in time and filled himself with tea, "Teacher Zhang, Teacher Li, as I said before, you just think of me as your student. From now on, in China Overseas University, I will take care of academic matters." There are still many things I need to learn from you."

Zhang Liangan and others could not sit still, so they quickly stood up: "It should be done."

While he was shocked, he also instantly understood why Qin Jingyu's self-study progress has been so rapid since he entered school, which can be called abnormal.

Now everything has the best explanation. They have been teachers for so many years, and it is not that they have never seen outstanding students, but Qin Jingyu is a different kind of existence. No wonder even the country calls him a genius boy.

At this age, to reach this point, he has already reached a height in the field of mathematics that others cannot reach in their lifetime. Just when people are curious about what he will do next, she starts from scratch and attacks physics!

This group of old guys really admires them!

After dinner, on the way home.

Professor Jiang drank some wine and was sleeping with her eyes closed. Qin Jingyu was still obsessed with the formula she was stuck on.

She found that the loop quantum gravity theory constructs a space-time background that can support string motion, but it also has a huge problem. The loop quantum gravity theory assumes that the cosmological constant must be small and negative.

She searched in the sea of ​​consciousness and found that this constant was the same as the result obtained from recorded astronomical observations, but according to string theory, the cosmological constant should be a very large positive value.

This is obviously the opposite.

When he saw the car approaching the small foreign-style building, Qin Jingyu felt that he couldn't think of a reason, so he said, "Grandpa Jiang."

Jiang Yuantao seemed to be waiting for her to speak and opened his eyes, "What's the matter?"

Qin Jingyu expressed his doubts about the hypothesis of the loop quantum gravity theory.

When Jiang Yuantao heard this, he did not answer the question immediately, but asked the driver to stop the car, "Would you like to accompany me, an old man, and get out of the car and walk for a while?"

Of course Qin Jingyu is willing.

As winter approaches, even the trees lose a lot of their vitality.

At dusk, an old man and a young man walked along the lakeside path and said: "Jingyu, you have fallen into a theoretical trap. Although the loop quantum gravity theory can reconstruct the huge four-dimensional space of our existence, it cannot construct strings. The remaining six dimensions of the theory that explain the properties of objects we observe.”

"One possible explanation is that these extra dimensions are not really space, but just a tool for us to do calculations in physics, which will eventually be replaced by a full four-dimensional string theory...

The four-dimensional space of the universe, in which the variable of time T is time T = speed V. Our time is defined on the basis of the speed of light C.

If a person stands on a globe and moves forward in the direction of light, compare it with moving forward at a constant speed. When the speed is the speed of light, the three-dimensional world of time stops. What will happen if the speed of light exceeds the speed? "

Qin Jingyu frowned and thought carefully while listening.

Yeah, what happens?

She seemed to have grabbed a few hand-cutting strings from it to separate her thoughts.

Seeing that the two of them were about to reach the small foreign building, Jiang Yuantao said again: "Would you like to sit in my study?"

Qin Jingyu shook his head, with confusion in his eyes: "I may need to be alone to think about it."

Jiang Yuantao patted her shoulder, "It's okay, kid, you still have a lot of time, you can take your time."

Unlike him, he is already approaching his seventies and doesn't know how long he can live.

Time was running out, and he didn't know if he would be too selfish by piling all his hopes and pressure on this young man.

Jiang Jibai sat in a wheelchair and watered the flowers in the yard. After waiting all day, Qin Jingyu and Jiang Yuantao finally appeared from far away.

He put down the watering can and raised a perfect arc on his face, because he said that his smile was alive and better looking.

But just when he opened his mouth to say hello, he saw Qin Jingyu looking worried and absentmindedly returning to his yard.

Seeing this, Jiang Jibai looked at Jiang Yuantao, who was standing there slightly absent-minded and with a guilty look on his face. However, he was only absent-minded for a moment before returning to normal.

When Jiang Yuantao approached, Jiang Jibai asked doubtfully: "Grandpa, what happened? What happened to Jingyu?"

Jiang Yuantao shook his head, but looked at the thin sweater on his body and said disapprovingly: "Nothing. It's you, the weather is cold, so why don't you wear more clothes? Don't you know that your body can't catch a cold?"

-

Qin Jingyu returned to the study, and Lei Wujie poured her a cup of hot water. She thought about it and said, "Change it to strong tea."

Lei Wujie frowned upon hearing this, "Are you going to stay up late again?"

Qin Jingyu: "I just have some doubts that need to be resolved."

It's not that she didn't feel that starting from today's open class, including the conversation on the roadside just now, Jiang Yuantao was intentionally or unintentionally causing her to enter an unknown and mysterious realm.

If her exploration of physics before was only based on the theoretical knowledge she continuously acquired, now she is about to officially enter the mysterious and dangerous but very fascinating field of physics.

She took out the pen and wrote down her understanding of string theory on the paper.

From energy = speed of light * square of mass, we can get that energy is mass, then the smallest particle in the universe is energy...
