Sunday, February 24.

Today is the second day of registration, and under the reluctant gaze of his mother and Chen Yayi, Su Yun got on the plane and returned to Peking University.

This is the fourth time that Su Yun has returned to Peking University, and each time he has a different state of mind.

The first time he came to Peking University, he also just came to this world, his heart was actually full of uneasiness and hesitation, and he could only paralyze himself by indulging in learning.

He was like a frightened bird about the world, but he still stirred his wings and flew forward.

The second time I returned to Peking University was after participating in the first "I Am the King of Singers".

He seemed to know a little more about the world.

The third time I returned to Peking University was after winning the "I Am the King of Singers" competition.

He seems to like the world a little.

The fourth time, which is now, is now.

Touching your heart, it's beating, looking forward to it.

With a slight smile on the corner of his mouth, Su Yun strode into the school gate.

.............

Back to the familiar library, A301.

With a plop, he waded into the big bed that he hadn't seen for a long time, and he hadn't cleaned it for more than a month, and the dust came to his nose.

But Su Yun didn't care, breathing in the smell of here.

Su Yun unexpectedly found that unconsciously, it seemed that this place also made him feel at home.

After not reading a book for a long time, Su Yun's heart was a little empty, so he didn't hesitate anymore and got up and went up to the sixth floor of the library.

As for why you want to go up to the sixth floor, it's because there, physics-related books are mainly stored.

He didn't need to read the computer books at all, because he couldn't learn anything from them.

The same goes for the books on mathematics, but the books on physics, some of which he has read, but relatively speaking, the least.

When he came to the sixth floor, Su Yun sighed first, Peking University has a lot of books.

I went around and didn't find the book I wanted to read, but I unexpectedly saw someone I knew.

"Boom! Temporary Mission: As the host of the strongest system in the universe, you should challenge and defeat all the conceited.

Objective: Provoke and break Shu Mengmeng's self-confidence, so that she knows that there is someone outside of the world.

System assistance: Comprehensive information has been collected and entered into Shumengmeng, which can be viewed on the homepage.

Completion Reward: +100 points, activate the health transfer function. ”

Su Yun was speechless and whispered:

"System, I told you not to sting, you just knock? I think you're really wise. ”

System:

"Thank you, host, for the compliment. ”

Su Yun:

“......”

After feeling that the system does not understand Chinese culture for a while, and after being broad and profound, Su Yun continued:

"I haven't seen you for a few days, I thought you were gone. ”

System:

"The host said that shut up the system, that's the strength of the system. ”

The system said proudly.

I'm telling you to shut up so you don't bother me to play Tetris!

Su Yun didn't know how to complain about this system, and said directly:

"I'm not going to do this task, you give up. ”

System:

“........”

The system stopped talking, and Su Yun didn't pay attention to it anymore, but walked towards Shu Mengmeng, who was sitting at the table and writing something.

When he first met the little girl, he didn't know the identity of the little girl, thinking that she was just a very ordinary little Lori who liked to see the scenery outside the plane.

It wasn't until later that Su Yun got it by chance, and it turned out that the little Lori who had a two-sided relationship at the beginning turned out to be the genius girl who was only fourteen years old and was exceptionally nominated as an associate professor by Peking University.

Silently walked up to her, and on her left hand side was a huge thick book, which formed a stark contrast to her little loli figure. And the hand, is writing something in a notebook at a rapid pace.

Su Yun stretched out his head and looked at Shu Mengmeng's notebook.

“△x△p& gt;=h\/4π”

"State Loss Ratio: & lt; m|n& gt;=δm，n”

“|i& gt; are orthogonal spatial base vectors to each other, |ψ& gt;=∑Ci|i& gt; is a Dirac function, satisfying orthogonal normalization. ”

"Satisfied: iη(a\/at)|m& gt;=H|m& gt;”

“∴H|m& gt;=En|m& gt;”

Shu Mengmeng's pen was fast, and several formulas were verified and written quickly.

Su Yun frowned and whispered:

"En is the eigenvalue of energy, H is the Hamiltonian operator.... In that case....."

Although it was very quiet, his voice still scared Shu Mengmeng, who was concentrating on calculating, a clever one.

Shu Mengmeng was frightened, her body shook, and the pen in her hand swiped directly from the top of the notebook to the bottom.

She turned her head cautiously, and when she saw Su Yun, her eyes suddenly lit up, and she said loudly:

"Big brother is you!"

I have to say that this is the gathering place of Peking University tyrants, and it is clear that today is the registration time, but some people can already be seen in the library one after another.

The library, which was originally audible in the falling pins, suddenly attracted everyone's attention because of Shu Mengmeng's voice.

Su Yun nodded with a smile, pointed to her notebook and said:

"Little sister, there's something wrong with your formula. ”

Shu Mengmeng, who was originally surprised, heard this, her face changed a little ugly, and she said loudly:

"No way! Every formula is absolutely correct!"

Su Yun still kept smiling, pointed to a formula and said:

"There is nothing wrong with the calculation of this formula behind you, but if you study quantum mechanics, there is a problem with the previous formula, I guess your previous inference is like this....." Su Yun took a pen next to her and wrote a few formulas in the notebook: "How about it, I'm right, right?"

Shu Mengmeng stood to the side with a cute face, holding her hands to her chest:

"Yes, I didn't think you were quite powerful, big brother, you really knew the formulas I wrote, but I have no problem with these formulas!"

Su Yun shook his head and said:

"There is no problem with your formula verification here, but have you ever thought that if you continue according to your logic, there will be a fork in the road here..."

Shu Mengmeng blinked her big eyes and said puzzledly:

"There's going to be a fork in the road here, but logically, it's perfectly fine!"

"Theoretically, it's fine, but you see...."Su Yun wrote down a few formulas in his notebook again: "When you do this, the two forks will continue to split into four, right? Then eight, if it continues, it will be 2 to the n-1 power of different branches..."

Shu Mengmeng smiled happily, as if she had mastered victory, and said:

"That's right, big brother, that's what you calculated! So, my verification method is absolutely feasible in theory!"

Su Yun shook his head and said:

"Theoretically, you're right, but according to the formula of the uncertainty principle: △x△p& gt;=h\/4π, then there is a conflict point with you. ”

Su Yun put down the pen and said:

"You should also know the uncertainty principle, you can't know the position of a particle and its velocity at the same time, and the uncertainty of the particle's position must be greater than or equal to Planx's constant divided by 4π, which shows that particles in the microscopic world behave very differently from macroscopic matter. ”

Su Yun looked at Shu Mengmeng, who no longer spoke, but looked contemplative, and continued: "Since we can't know all the details now, it's a matter of principle. According to your logic, it is theoretically feasible, but logically it does not make sense. ”

Shu Mengmeng kept looking at her notebook and the formulas written by Su Yun.

At this time, a tall boy suddenly walked over, Student A, and said in a slightly angry voice:

"Classmate, can you speak quietly? This is the library, not a place for you to discuss!"

Shu Mengmeng kept looking at the notebook, thinking about something, Su Yun just stood aside like that, looking at this little Lori, and neither of them seemed to hear what he said.

Student A stood aside a little awkwardly, not knowing what to say.

Seeing that the two of them were no longer discussing, he couldn't say anything more, and turned back to his seat.

As a result, just as he picked up the book and was about to read it.

"I see! If I continue to do this, at about 2 to the power of an-i, the Dirac function, satisfying orthogonal normalization, will be meaningless!"

Boy A:

“.......”
