Chapter 5: problem

When I left the lecture hall, Lin was very relieved.
I haven't studied mathematics well. What can I do if I can't do it?
However, there were too many bus people on the way home, and she was squeezed all the way. After getting off the bus, her mentality collapsed a bit.
The sky is completely dark.
The barbecue stall outside the village has been set up, and the smoky squid, kebabs and grilled scallops scented the four fields.
Standing in front of the familiar barbecue stall, she was full of the back of her eyes when she left, and she was so hungry that she sent a WeChat to Lao Lin to come down and eat.
Lao Lin fell back soon - [Miao Wei].
Holding the phone at the wind up, she ordered something they would normally order. But things are half baked, and there is no old forest figure at the entrance of Xincun. Looking at the black and lonely iron gate, Lin Chaoxi suddenly made a bad premonition.
Her hand was shaking when she called out the old forest phone.
Around the crowd, she could only hear the "beep...beep..." waiting tone in the phone.
The heart sank into the bottom of the water, and where did her brain break? I was looking for my father to go downstairs to have a barbecue!
After the phone was answered no, the forest decided to give up and fight again. She greeted the owner of the barbecue booth and ran to the entrance of Xincun.
Lao Lin is still at home when chatting on WeChat. If Lao Lin does not leave from the back door, he may still be at home...
But why not answer the phone?
In just a few minutes, Lin has a lot of possibilities in his mind.
She rushed to the door of the house, suddenly, saw a leisurely figure under the tree.
Old man's sweatshirt, squatting plastic slippers, a hand bored to tease the wild cat passing by.
moment……
Numerous airs poured into the chest instantly, and Lin’s legs were soft and almost slammed.
After adjusting her mood, she was in front of the old forest.
Lao Lin looked up, very surprised: "Why are you running back, lose weight?"
Lin Chaoxi’s heart flashed a bad hunch, and Lao Lin seemed to completely forget about their barbecue.
"How are you here?" She asked a sentence that was not wrong, and asked him.
"Throw the trash and forget the key, wait for my niece to come back to save, and feed the mosquito by the way."
"Your mobile phone, I will call you for a long time."
"Whoever throws the trash and takes a cell phone."
The old forest is straightforward and strong, as if the mistakes are normal. The heart sinks again, and the old forest fruit really doesn't remember.
Forgetting what has happened recently is difficult for planning what is going to happen, which is normal for Alzheimer's patients.
She has not encountered a similar situation.
But now, under this tree, facing the father who is full of doubts, she is only deeply weak.
Human beings are too vulnerable to disease, and there is no way.
Looking at his father, Lin Chaoxi forced himself to laugh and pretend that nothing happened.
"Is Lin, is your meal ready, I am starving to death."
"Do I forget something?" The old man is too smart.
"Yeah, guess what you forgot?"
Lin Chaoxi pulled her up and pushed him into the door.
Until the door is in front of the house, Lao Lin is silent.
But when the door opened, he shouted "worse" and went straight to the kitchen.
There was a bit of burnt smell in the air, and Lin did not care for him.
She looked around the house and saw her father's cell phone on the shoe. She quietly walked over to unlock, on the WeChat interface, she sent an invitation and Lao Lin's reply.
"Hey, I turned off the fire, and I really demented?" Lao Lin took a deep breath in the kitchen.
Looking at his father's happy and busy figure in the kitchen, Lin decided to delete the whole conversation.
"What are you eating today?" she put down her cell phone and shouted.
......
She did not know what she was thinking at the time. Anyway, the move to delete the WeChat dialogue lasted for 58 minutes and was discovered by her dad.
Lao Lin has been skeptical that she did not tell the truth. After dinner, she was washing the dishes, and Lao Lin went straight into the study and opened the computer version of WeChat.
She washed the bowl out and Lao Lin sat on the living room sofa. Did not turn on the light, his face was blue and green, and he did not say a word.
The smell in the air is very bad.
In the memory, Lao Lin made this posture last time, or when she was in the high Chinese science division, she chose the liberal arts for a while.
Lin first eve the first reaction is to run, the second reaction is not to run. She has read too many Alzheimer-related materials, and emotional instability is one of the problems caused by this disease.
She turned her head with her scalp, rubbed her hand on the apron, walked toward the sofa, and cautiously asked, "Dad?"
Did not respond.
She glimpsed the computer version of WeChat, which is faintly visible in the computer screen of the study room, and instantly understood what was going on.
She crouched down and hurriedly admit her mistake: "I'm sorry, I just thought, you will not be happy when you see that one, it doesn't matter if you don't see it..."
"Do you think that Dad's brain is not working?" Lao Lin was cold.
"No no……"
"Then how do you think that your father will be angry with her daughter because of her kindness?"
Lin Zhaoxi looked up a little, very surprised: "Hey... why is that?"
"Are you going to blind date?"
She stunned. In short, she guessed countless reasons, but never thought it was because of this.
Lao Lin’s face is still very difficult to see, and the heart is unpredictable.
"How do you know?"
"Oh, I don't want you to say that the instructor of your internship school is my classmate. He learned about my illness from my niece, and I am very concerned. At the same time, she further reported to me that your relatives were very compassionate. After considering my condition, I decided to continue to include you in their son's harem, brackets, and downgraded to one of the candidates. I hope we will continue to work hard."
"..."
"What the are you thinking?" Lao Lin was very harsh.
"It is the age... It seems that I should find a boyfriend."
The ghost made the difference, Lin did not explain to Lao Lin, in fact, before entering the cafe, she did not know that it was a blind date.

Like? What is your life plan?

"As a teacher." Lin answered.
"Hey? So you really want to make a boyfriend to go to a blind date, really like a student to be a teacher?"
Lin Zhaoxi couldn't answer it positively. She said: "Comrade Lao Lin, you should know better than anyone else. This world is not what you like to do."
For example, if you like mathematics, you can only give up your studies.
I like it, but I can only hope to sigh.
Growing up, isn't it to learn to compromise with this world?
After she finished the sentence, Lao Lin did not say anything.
Lao Lin just looked at her deeply.
When she gave up studying the Olympics, he had seen the look of Lao Lin; when she and Lao Lin argued for the liberal arts, he also saw the look of Lao Lin.
He was disappointed with her decision, but restrained the impulse to influence her life.
People must be responsible for their own decisions. This is Lao Lin’s life creed.
Lin Chaoxi took a deep breath and held his knees to stand up.
"Have you ever thought about it..." Lao Lin did not give up this time and continued to follow the temptation. "After ten or twenty years, I will finally lie on my bed. When you think of today's conversation in front of my bed, you will what you want to say?"
"Dad, how many passwords are there?"
"215000."
After answering the old answer, Lao Lin also took a note on the sofa and warned her: "Comrade Lin Chaoxi, don't just talk about the day."
Lin Zhaoxi: "...."
"Let's think about it again. At that time, would you regret that you could not pursue your dreams at the age when you can pursue your dreams?"
Lin Chaoxi stood in front of the sofa, there was no light in the room, and the wall was dim in the distance.
Dream, what is her dream?
The old chicken lingering chicken soup is very fragrant, she could not help but recall the ambiguous problem, and the irritating feeling that she wanted to answer it at the time but had to give up because of lack of ability.
It should be annoying...
She looked at Lao Lin and said, "There is a question."
ten minutes later.
Lao Lin put down the pencil for the calculation and asked, "Would you like it?"
"..."
Lao Lin said with emotion: "So you said that you are like a pro, obviously there are such excellent boys not to chase."
Lin Zhaoxi: "I still like the shark, can I catch up?"
Lao Lin: "Who is that?"
Lin Zhaoxi: "Million magnetic king."
Lao Lin: "So smart, I like it too."
"..."
"That is to say, if you solve this problem, you promise to be your boyfriend?"
"Can you not fall in love with this brain? This is the introductory question to join the modeling contest team."
"I'm afraid not." Lao Lin's tone is too calm.
"I do not understand."
"This is a stone that asks for a stone." Lao Lin took off the reading glasses and looked far-sighted. "It is not the road to modeling competition, but the p/np problem."
Lin Zhaoxi looked at the subject again and finally understood the feeling that I had learned that only the scales were caught.
The p/np issue, one of the Millennium issues, the million dollar bonus, juxtaposed with the Riemann hypothesis, and the Poincare conjecture.
It’s really...
"Ambitious." Lao Lin was very pleased with the sound. "I am correcting myself. This should not be a problem. This is the meaning of the tutor. Is the professor of your school's mathematics research in the Hamilton circuit exactly?裴 导 导 , , , , , , , , , , ,
Lin said without a word: "You know too much about this."
"Not much, I also know that although there is still a very long distance between this issue and the real solution of p/np. But to solve it and rewrite the history of human history, some people have such courage and deserve respect."
"Well, yeah." Lin Xiangxi thought, courage, really enviable.
"Then do you want to take a postgraduate degree in mathematics at your school?" Lao Lin said.
Lin Xiangxi looked at him with dementia, I don't know how the topic would touch this.
"Strengthen p=np, greatly improve the computer computing speed, countless diseases and even Alzheimer's, the time to overcome them will inevitably be greatly shortened..." Lao Lin continued to express his feelings, "I will not consider turning a professional for your dad." ?"
Lin Chaoxi pointed to himself and pointed to the question on the table: "Da, I can't even understand it. I have a whole four years of professional study time between mathematics and postgraduate study!"
Lao Lin smiled and said: "You don't think you can catch up with it, but is the distance between you and him farther than the p/np problem?"
It is simply impossible to refute.
Lin turned around and walked to his door.
Lao Lin is still laughing, and a low, hoarse smile rang behind her.
"Miss Lin Xixi, in this long and beautiful life, if you really find what you want to do, then whenever you decide to start again, it is not too late."
