Chapter 829

When Lu Zhou finished lunch, the lunch break was almost over.

He walked back to the experimental building of several institutes with Lu Zhou and asked him again and again not to forget about the Russian delegation. Chen Yushan waved goodbye to him reluctantly, then turned around and left.

Back in the office, Lu Zhou tidied up the lesson plan that he had taken time to arrange yesterday, found assistant Zhao to confirm the lesson schedule in the afternoon, and then yawned to the teaching building a.

There is a number theory class this afternoon. It's a professional elective course with credits.

Originally, he Changwen, a doctoral student, helped to take these courses, but seeing that half of this semester has passed, Lu Zhou thought about how he had to show his face, so he went there in person.

I don't know if it's his illusion. I always think that the students in the classroom spend more time staring at his face than at the blackboard

Aware of this, the boat can not help but feel a little depressed.

I didn't expect that I haven't taught undergraduate students for such a long time, and my teaching level has retreated to the extent that I need to rely on my face to eat.

When I think back to my lecture at Princeton University, when I was sitting in the corridor with a small bench in other departments' shoes, I was very sad for a while.

It seems that we need to find more opportunities in the future when we have time to attend classes in person

Before long, all the blackboards were full, and the bell for the half-time break just sounded outside the classroom.

Lu Zhou closed his books and looked at the students who did not blink under the stage. They were preparing to make a summary of what they had said before. Then they saw a line of light blue windows floating in his vision.

[

completion of branch line task:

④ Alchemist: production of 100 tons (100 / 100) titanium alloy.

]

done?

So fast?

There was a flash of surprise in Lu Zhou's heart, but his face didn't show it.

After clearing his throat, he piled the teaching plan on the desk, looked around the students in the classroom and said.

"That's the end of the class. Let's take a five minute break and continue later."

After that, Lu Zhou left the classroom and walked into the toilet beside the classroom. After finding a single room to squat down, he silently read the system and entered a pure white system space.

Quickly walked to the side of the holographic panel, and as his index finger crossed the screen, the task panel soon appeared in front of him.

[

the second stage of "control of the earth and the moon" -- "permanent presence of the moon"

branch line:

① overcrowding: the monthly active population exceeds 100 within 24 hours.

② Future spark: Large Hadron Collider on the moon.

③ Dig three feet: collect 50 tons of rare earth from the lunar soil.

④ Alchemist: produce 100 tons of titanium alloy. (completed)

⑤ looking back at the parent star: establish a semi permanent earth meteorological observation station in the orbit of the moon.

⑥ Looking far away: a large space telescope is built on the back of the moon to make more detailed observations of the planets in the solar system and the extraterrestrial stellar system.

]

looking at the "completed suffix", Lu Zhou could not help feeling.

He started the whole project when he approved the funds. He sat on the earth and waited for a few months before the task was completed.

It's easier than hanging up.

The only drawback is that until the main task of the second phase is completed, the reward for the branch task is temporarily invisible.

I don't know what benefits this regional mission can bring to him

“…… Are there five branches left? "

Looking at the remaining tasks on the task list, the boat touched its chin.

The first one is very easy to solve. It's good to organize 100 people to brush one wave with tourism or other ways. It may not be easy to do last year, but now magpie bridge is finished. It's not too easy to solve this task. It's not easy to say that you can make a profit.

There is also a third branch line, which can excavate titanium ore from the moon, so it can excavate rare earth ore. As for the smelting of rare earth, it may be a bit troublesome, but the task only requires collection, and there is no requirement for smelting. It should be profitable to transport it back to the earth.

As for the other tasks, we can only say that they are incidental.

It's not realistic to complete all the branch lines. It's not a loss for him to be able to complete more than half of them.

After retreating from the system space, the boat was getting ready to stand up from the toilet, and heard the sound of the faucet flushing from outside.

At first, he didn't care about it. He was going to go out directly, but he just heard two students outside say their names. So he sat back again and listened curiously.

As a professor, he is still curious about the students' evaluation of himself."Do you understand Lu Shen's lesson?"

"Half, and you?"

The boy with glasses sighed and said, "one third of you, ah, I want to understand too, but the strength is not allowed."

The man who washed his hands beside the station shook his hands: "maybe this is Daniel."

Glasses man: "maybe! But when I think of the fact that Lu Shen is a single dog, my mind is in balance. At least I have a girlfriend

"Ha ha, how do you know they are single dogs? Maybe they are just low-key?"

The man with glasses waved his hand and said, "what do you know?".

"Come on, I can see if I'm single."

At this time, a voice with a little familiarity and a little smile suddenly came from behind like a ghost.

"Is it? Then teach me how to look. "

Standing beside the washbasin, the two men turned around together. When they saw the boat standing at the door of the single room, they saw a ghost on their face.

"Lying trough, land God!"

"Professor Lu?!"

Lu Zhou smiled and didn't speak. He just looked at them.

"Teach, Professor We just... " Professor Lu looked at his hair with a smile like eyes. The student with glasses scratched his back of the head. He scratched his ears and cheeks in a hurry. Suddenly, he got an idea and said, "we were just praising you for your handsome!"

Lu Zhou: "..."

MMP！

When I'm deaf?

What's more, do you need to boast about it?

Do not want to waste time with two people, land boat face said: "hurry back to class."

"Yes!"

The two students stood up straight and ran away.

Looking at the direction of the toilet door, after a while, the boat sighed.

Well, I didn't realize it before. Now he finds that it's really cool to be a professor.

But

After all, have you set a bad example? What strange misconceptions do these undergraduates have about the profession of mathematician?

In fact, his age is not small, at least not young.

I'm afraid that my father and mother should be worried about his life.

“…… Well, let's wait two years before we think about it. "

Shaking his head, Lu Zhou put the problem aside for the time being.

He is not entirely avoiding the question.

It's just that he hasn't yet figured out how to build a family and keep it going.

Research has taken up most of his time. He has no energy to play the role of a boyfriend, let alone a father

Turning back to the classroom, Lu Zhou opened the lesson plan on the desk and turned to the last page.

"Turn your textbook to page 47."

In the classroom, there was a sound of turning over the books. Just read the content on page 47, many students' faces were surprised.

“…… The first half of the class is about the basis of number theory. The second half of the class, I will tell you something interesting, which is also the subject I am studying. "

With that, he turned to face the blackboard, picked up the chalk from under the blackboard, and wrote four words on it.

[Riemann conjecture]

in the moment of writing these four words, there was a commotion in the classroom.

The boat clapped on the blackboard to show the students to turn their attention to this side, and said in a clear voice.

"I speak fast."

"Listen carefully."
