I really don't want to lie down and win

"Okay okay."

The sound of the conversation between Xu Mang and Yang Jian reached the ears of the mother and daughter. Xiaoman hurried out and called her father to the kitchen.

Yang Jian originally wanted to chat with Xu Mang about the location of the laboratory, but he was called to the kitchen for no reason. Seeing that his wife was there, he asked curiously, "Xiaoman? Call your father to the kitchen to make What?"

"Uh..."

"The day after tomorrow, my mother will ask you to work overtime, all night." Yang Xiaoman said.

"what?"

"But there is nothing in my company." Yang Jian asked with a puzzled face, "There is no need to work overtime, right?"

"If you are asked to work overtime, then work overtime."

"Do not talk nonsense!"

Although Yang's mother was very dissatisfied with her daughter's shifting the responsibility to herself, everything had already happened, so she could only bite the bullet and admit it.

"Oh."

"Maybe...maybe something happens the day after tomorrow." Yang Jian said with a wry smile.

After getting the answer from his parents, Yang Xiaoman was very satisfied with it, the day after tomorrow will definitely be a wasted night.

after that,

Xu Mang and Xiaoman's family had dinner, and then sat on the sofa with his father-in-law, chatting about the location of the laboratory. According to Yang Jian, the piece of land approved by the above was relatively remote, but fortunately it was No money.

After explaining, Xu Mang knew the reason for not needing money. The year before last, a notice was issued to comprehensively strengthen the level of scientific research and education in various places, and this laboratory happened to catch a ride.

"I have already asked someone about the equipment. Generally speaking, this kind of thing needs to be made by myself, but I am afraid that you will not have enough time, so I choose to import it." Yang Jian said: "It is estimated that the slowest time is half a year, and you can Use the lab."

"Half a year?"

"Quite soon." Xu Mang nodded and said seriously.

"Your performance has been very good recently." Yang Jian said with a smile: "Many people have mentioned your success in scientific research and education, which makes me look good!"

on top,

Almost everyone knows that Xu Mang is Yang Jian's son-in-law. Although Xiaoman will only turn eighteen next year, it does no harm to Xu Mang. In the talent introduction plan, Xu Mang's name is different from others, and it belongs to the bold one. .

bold,

It means that it must be won without sacrificing much price.

"The Chinese New Year will be one and a half months away. I plan to go to Ning City with your aunt on January [-] to meet your parents." Yang Jian said, "Confirm the matter between you and Xiaoman as soon as possible. There is no way to do it."

"Oh..."

"Then Xiaoman and I will go together," Xu Mang said.

...

On the afternoon before Christmas Eve,

Xu Mang is staying in the laboratory, and the progress of the cooperation project with Tsinghua University is not very good at present, and has encountered many, many bottlenecks. These bottlenecks are not a problem to Xu Mang, but to Lin Wanwan later. In human terms, it is not a small challenge.

Following the plan to stop destroying other people's beautiful daydreams, Xu Mang just gave some pointers, and then fell asleep on the table.

Yesterday, Xu Mang went to Director Fang of the Department of Physics and told him the current progress. If he didn't intervene, it would probably be postponed indefinitely. Intervene in it, only allowed to guide on the sidelines.

Xu Mang was very helpless, but the reason given by the other party made him unable to refuse. Now the country needs a lot of scientific and technological talents, and one person alone is not enough.

finally,

Xu not only has to undertake scientific research, but also undertakes the important task of cultivating scientific and technological talents.

"Teacher Xu!"

"Can you answer this question for me?" Zhang Xu called to the drowsy Xu Mang.

"Oh..."

Standing up to Zhang Xu, Xu Mang glanced at the model on the computer, and said slowly, "The free electrons in the metal will not escape from the metal spontaneously, because they can only move in the periodic field formed by the positive ions. .”

"So... you have a problem with this." Xu Mang said: "At x0 or xa on the boundary, because the potential energy suddenly increases to infinity, the particle is subjected to an infinite force pointing to the well, so the position of the particle can only be inside .”

"..."

"Teacher Xu?"

"How can I be as good as you?" Zhang Xu said with admiration, "Are you a robot?"

"Have you ever seen such a handsome robot?" Xu Mang rolled his eyes, gave a huff, and said to the five people in the laboratory: "Tomorrow Christmas Eve, and the day after tomorrow Christmas, we will rest for two days to be with our boyfriend." Accompany your boyfriend, accompany your girlfriend, accompany your girlfriend, if you have nothing...then come to work."

After hearing Xu Mang's words, they were all very sad because they were all single.

"Ugh?"

"Mr. Xu!" Li Tao said with a serious face while holding his mobile phone: "Just now wechat pushed a piece of news, what did you say... a couple in a certain place embraced and kissed on the flyover, and they both fell from the flyover to the ground .”

"The two were seriously injured. One died on the spot, and the other died after being sent to the hospital." After reading the news, Li Tao looked at Xu Mang and said, "Mr.

Xu Mang: 囧

After thinking for a while, he took a pen and wrote a question on paper, handed it to Li Tao himself, and said with a dark face, "Give me the answer to this question when you come back from Christmas."

words fell,

Xu Mang left the laboratory directly.

"???"

what's the situation?

Li Tao glanced at the title, and it was just a few words, the projection of spin angular momentum in any direction, its eigenvalues ​​and eigenvectors.

What the hell!

This...

This is slaughter!

"Comrades!"

"You guys have to help me!" Li Tao said with tears in his eyes, "I accidentally stepped on a thunderbolt."
