He hurriedly stood up and said humbly, "Professor Guan, you are being polite.

I can do it myself. "

Gong Youhong glanced at Guan Guohai, and reminded the latter: "Old Guan, don't waste time on such trivial matters.

Mr. Lin is here to see Li Ning, you let him come out to meet people. "

Guan Guohai was like waking up from a dream, and nodded with joy, "Okay, okay, then I'll call that kid over.

Mr. Lin, wait a moment. "

After finishing speaking, the old professor walked out of the room, turned around and walked into the side room of the single-family courtyard. After a while, he dragged a man in disheveled clothes, only wearing a vest, shorts and flip-flops, and walked in.

The latter has a chicken nest head and seems to have just woken up. When he walked in with the teacher, he was still yawning indistinctly.

Guan Guohai dragged the students into the room, and at the same time said with hatred: "I told you to pay attention to your image, but you didn't listen! You dress like this, and you don't wash your hands. How to meet people!"

The reprimanded Jiwotou scratched his hair and didn't speak. After following Guan Guohai into the house, he turned around and closed the door.

The sour smell of sweat immediately filled the originally fairly fresh air.

Gong Youhong raised his eyebrows unconsciously, then held back very well, and looked at Lin Duan with a smile: "Mr. Lin, Li Ning is a weird person.

It's been like this all year round, don't be too surprised. "

Lin Duan was a little ashamed, so he could only bite the bullet and smile: "No, no.

Genius, a little maverick, it should be. "

Guan Guohai on the side heaved a sigh of relief, then pulled his student, pointed to the manuscript on the table, and asked loudly: "Li Ning, tell me, did you draw that manuscript?"

After listening to the teacher's words, some men who had been distracted all the time raised their heads slightly to look at the manuscript on the table. After a moment of surprise, they nodded: "I drew it."

Chapter 662 Teacher, I have to eat

"The manuscript is inspired by the cardioid. I think that since Descartes can use the method of analytic geometry to graphically express the formula on the Cartesian coordinate system, it must exist in other graphics and can also be constructed in this way."

"Heart-shaped graphs, rhombus graphs, fishtails, and smile curves can be completed by expressing these formulas on the coordinate system, and then using a computer to draw the graphs."

"Underwear is symmetrical.

Design a pattern, and of course the same pattern on the other side. They are circles, so the design is actually not complicated. "

In the room with the door closed, the three of Lin Duan sat on the chairs, watching the chicken-wotou boy in front of them chatting eloquently.

The expressions on the faces of the three people are different.

Lin Duan was surprised, Gong Youhong was ecstatic, and as a teacher, Guan Guohai felt helpless not knowing whether to cry or laugh.

He really didn't expect that his proud disciple would use mathematics in such a way.

useless?

it works.

is that useful?

There doesn't seem to be too useful.

In comparison, aren't the topics I researched more significant?

After Li Ning finished his narration, Guan Guohai coughed and said with a serious face: "Li Ning, you are my favorite student.

Your math talent is the highest I have ever met.

With your talent and ability, as long as you are willing to study hard, it is very possible to overcome those centuries-old problems in the mathematics world!How can you" "Teacher.

I have to eat. "

Li Ning interrupted Guan Guohai, and his light words made the latter's throat stop abruptly as if something was stuck.

Guan Guohai opened his mouth, and after a long time, he finally choked out a sentence: "I asked you to stay in school to be my assistant, and the school will provide subsidies."

"That's only enough for my daily expenses. I still have my parents to support me, I have two younger sisters who need to go to school, I still need to buy a house in the capital, I need to fall in love, get married and have children."

Li Ning replied lightly.

This time, Guan Guohai stopped talking.

I only heard Li Ning continue to say: "Mathematicians are different from other scientists. No matter how advanced the research is, it can't immediately put the research results into practice. I can't live on that little salary."

Guan Guohai got a little angry, he patted the table and said, "What are you talking about, when we were young, how could we have the living conditions you have now.

Do you know that your current monthly salary could have been paid to me for several years back then! "

"Back then you used 300 yuan to marry your mistress, but now my 300 yuan is only enough to treat a girl to a hot pot."

Li Ning said.

Guan Guohai was stunned, and after a while, he sighed weakly and waved his hands: "Let's go.

I can't stop you, and I shouldn't stop you.

You are right, you have to live, and staying with me in this school is really wasting your youth. "

"No matter how good mathematics is, it can't make you full."

Lin Duan and Gong Youhong listened and watched, with helplessness and sympathy on their faces.

Immediately, Gong Youhong whispered in Lin Duan's ear and said to him: "Li Ning is good at mathematics, but he has some flaws in character and is not good at dealing with strangers. But tried several times without success.

Later, I could only do research with Laoguan in this small courtyard in Qingbei, as a deputy, and accumulate qualifications. "

"But there are elderly parents in his family, and two younger sisters waiting to go to college to pay tuition fees, and he is old enough to marry a wife and have children, and there are places where money is used everywhere.

How can that little salary be enough? "

"A mathematician, it sounds like a tall man, but the money he earns is not even as good as those who work outside the construction site."

After hearing this, Lin Duan felt the same way.

As a man, he knows the power of money too well.

Young people like Li Ning, if they have no money, will not only face the pressure brought by life, but also the ridicule and blank stares of their peers, as well as the expectations and disappointments of their elders. They may not be affected by the hard life. Defeated, but few people can withstand the accusations and doubts of the closest people.

Thinking of this, Lin Duan said: "Mr. Li Ning, are you interested in working in Fangyuan Clothing?"

Li Ning was taken aback when he heard this: "A clothing company?
