I really don't want to lie down and win

This...

The blond woman's face was full of confusion, and her expression gradually became a little lost.

"Cathy!"

"Taking carbon dioxide structure OCO, a straight-line molecule, assuming that the equilibrium distance between two adjacent atoms is a, and the elastic force coefficient between two adjacent atoms is k, what is the Hamilton quantity? Please come up and write its expression."

The professor suddenly asked the confused blond woman.

The sudden question made the girl even more confused. She had been chatting with Xu Mang just now, and then missed a period of time and space. When she came back to her senses, she found that the world had changed. Why did she suddenly feel the vibration of the three-atom linear molecule?

Oops,

totally no idea.

The blond girl was a little frustrated, and even a little scared at the moment, fearing that her credits would be affected.

At this time,

Xu Mang silently took a pen and wrote down an equation in a notepad, which is the general form of the Hamiltonian, but changed according to the structure of carbon dioxide.

finish writing,

Xu Mang pointed to the above equation.

After seeing the equation written by Xu Mang, the blond girl from Casey was a little overwhelmed. She didn't believe that a genius could give an answer to such a professional physics problem. It must be unreliable.

But right now I have no other choice...

finally,

The blond girl could only walk slowly to the front of the podium according to the equation given by Xu Mang. This short ten-second journey was a century long in Casey's spiritual world.

The professor didn't think Kathy could write this equation, and the reason why she was allowed to take the stage was just to give her a warning, warning her not to do something that had nothing to do with the class during the class, such as staring at the boy.

in panic,

Casey wrote down an equation that Xu Mang gave her, looked at the professor cautiously, and said, "Professor...that's it."

"..."

she will?

Impossible!

Have already previewed this part in advance?

When the professor saw that Casey had actually written out the equation without any mistakes, he was a little confused for a moment.

"Not bad!"

"It seems that you have previewed the approximate method of quantum mechanics in advance." The professor could only praise Casey along the words: "Go back."

what?

That's... that's right?

No way?

Hearing what the professor said, the girl, Casey, realized that the guy sitting in her seat was, yes... that guy who was extremely narcissistic. He had a little deep understanding of physics, and felt that he didn't have much class, even There are no books.

Come confused,

go confused,

Casey still can't figure out why that boy can know this equation, and he doesn't look like a schoolmaster.

Back in his seat, Casey took a serious look at Xu Mang. This man with an oriental face looked a little...cute. With a little nasty.

look familiar!

Looks familiar... I've vaguely seen him somewhere, but I just can't remember who he is.

"Who the hell are you?" Casey asked.

"I am me...a different fireworks." Xu Mang smiled and said calmly.

Neuropathy!

Casey directly defined Xu Mang as a neuropathy, and he was seriously ill, but...he also suffered a lot of harm because of it. If he didn't know about a problem that he knew about neuropathy, he would be worse than a neuropathy.

The class was still going on, but Xu Mang couldn't stand the sleepy mind anymore. body.

Xu Mang fell asleep sitting up.

Very fragrant, deep and beautiful...

"When using the variational principle to deal with practical problems, another common method is to approximate the general form of the wave function, and then use the variational principle to obtain the corresponding energy proof equation." The professor said seriously: "This equation It is much easier than the original wave equation, and in the process of solving it..."

In the middle of the conversation,

The professor saw a speechless scene where a student fell asleep sitting up.

but...

At this time, the professor suddenly felt that the sleeping student looked familiar.

correct!

He is Xu Mang, right?

The professor finally remembered who the sleeping young man was, and had seen photos of him several times in Nature journals.

By the way, why did he appear here?

Oh!

A recent press conference.

"Hey!"

"Don't go to sleep!" Casey hurriedly pushed Xu Mang beside him, and said seriously, "What's the matter with you? Are you crazy? This is Professor Jeff's quantum mechanics class, don't you want to be in school?" Do you want to stay?"

Xu Mang woke up with a cute expression on his face. He felt that the two decisions he regretted the most in his life, one was to marry Xiaoman as his wife, and the other was to come to this classroom to attend lectures. This professor named Jeff, There is no tension in the words, a little lifeless.
