Tech Hammer

"What are you two muttering about?"

"Hey, Sister Min, are you back? Come and help us find out, what does this mean?"

"what do you mean?"

"Just this, U!/U!(I-U)!, like a mathematical expression?"

"Well, the factorial of U is multiplied by the factorial of U multiplied by the factorial of I-U. The permutation and combination formula is, the result is I choose U."

"Oh my god, Sister Min, what are you studying journalism? Really, it's a pity not to study science. You even know mathematics! Wait, I choose U, I choose you? What does it mean to post such a picture on WeChat Moments? Huh? This question shouldn't be difficult, right? Sister Min."

"The transformation of permutation and combination formulas in statistics. I don't remember whether I learned it in high school or in advanced mathematics, but it is definitely not difficult. However, it is quite innovative to think of saying this sentence in this way. This is Whose circle of friends is this?”

"Chen Diancheng's."

"Ah? That President Ningshe who has been in the limelight recently? Isn't that right? Momo, how come you have his WeChat account?"

"Well... today he went to a cafe with an uncle to eat. When we were paying, we chatted for a while. He said he could get me into a foodie group at Yanbei University, and then we added WeChat. "Wen Yimo repeated what happened today blankly.

"Foodie group? Since when did Yanbei University have a foodie group? Which group is it? Can we check it out?"

"What's the inconvenience? Well...that's it, Yanbei University Foodie Alliance. It's quite lively inside, and everyone is discussing what delicious food..."

"Look...does what they are talking about really have to do with food?"

"Chen Diancheng said that there are many majors in this group who probably like to use mathematics to express food, right?"

"...Momo, this is no problem, but you didn't find the biggest problem?"

"Huh? What's the problem?"

"There are more than a hundred people in such a big group. Look, the people talking in the group are all boys. Let's take a look... Look, the proportion of boys is 100%, right? From what I know about my boyfriend, Even if boys are really foodies, most of them are too lazy to share, let alone share in the group. If they can think of mentioning it in the dormitory, it is when they are very hungry. If they really want to share, change it to a game. The group is pretty much the same!”

"Uh? Really? Sister Min?"

"No, Momo, I should also have a say in this aspect, and my boyfriend is the same. I tell him where the food is delicious, but he never remembers it. When I go to where the fun is, he can remember it very clearly. So. There is reason to suspect that this is a temporary group created to fool people!"

When the four girls in the dormitory participated in the discussion, Wen Yimo felt confused...

The sisters who slept together seemed to have a point. The key is that it’s really hard to understand a food group filled with boys. As we all know, Yanbei University has a much better balance of male and female students than the school next door. Basically, it has been maintained at around 6:4 over the years, which is far better than the 2:1 balance next door. Therefore, it is a delicious food for the entire school. There are only boys in the group, which is indeed not normal.

"Then...then...then why did he add my WeChat account and then drag me into this group?" Wen Yimo asked dully.

This question caused a brief silence in the dormitory.

The three sisters in the dormitory looked at Wen Yimo in strange and interesting ways...

"Hey, what are you looking at? Can you tell me something?"

"Isn't it very clear in this circle of friends? He chose you!"

"Pfft... Haha... You are so funny, why did he choose me... We don't know each other at all... Haha... Huh? Hey, sisters, are you serious?"

"This is very easy to prove. Chen Diancheng is from the School of Mathematics. He posted this to Moments inexplicably, and he created this new group chat, which is enough to prove that many of his WeChat friends are boys studying mathematics and science and engineering. Therefore, it is absolutely impossible for this formula to be fully disclosed. I even suspect that this circle of friends is only open to you. If you look at the circle of friends, there is not a single comment. Of course, it may be that you have no friends, so we only We need to verify that we are also Chen Diancheng’s WeChat friends and see if they can see this circle of friends.”

"Ah? How... how to verify this?" Wen Yimo looked blankly at Sister Min, the oldest in the dormitory, and asked.

"Oh, what's so hard to verify? Let's just find a way to find someone to ask. Who knows Ning Ban?"

"Wait a minute, I have a fellow from the Academy of Planning and Science. Someone in their major must know the members of Ning Society. Can I ask him to help inquire?"

"Then why are you still standing there? Just ask?"

"Hmm...wait a minute, I'll send you a WeChat voice message."

"Hey, Brother Liu, I'm Lin Xiaoqi. I want to ask you for a favor... Hmm, do you know anyone who has Chen Diancheng on WeChat? That's the president of Ningshe. ...No, no, no, no I want to get his WeChat account just because I want to see what Moments he just posted. It would be best if he could take a screenshot and send it to us... Huh? There is one in the dormitory next door to you? Okay, I'll wait. Thank you, Liu elder brother!"

five minutes later……

"It's been sent, it's been sent..."

"have a look……"

"Haha... my judgment is correct! Sure enough, it's not, Momo, hurry up and see if it's a stone hammer?"

"It's over, Momo, do you understand now? You are the food for others!"

"Pfft...Xiaoqi, you are so damaged!"

"Hey, don't be like this. Is it just a misunderstanding? We haven't met each other a few times. Today he ordered two portions of my favorite fat beef bibimbap, so I couldn't help but ask. He said a word, and then we talked about food! How could it be like this all of a sudden? "

"Wait, fat beef bibimbap? Did you recommend it to us in the dormitory last time? And then you also posted it on BBS and food review software? You said it was to promote the cafe?"

"OK……"

"It's over, Momo-san. He may have been paying attention to you for a long time. This is obviously premeditated... Ahem... By the way, have you often seen him in the coffee shop recently?"

"It seems that I have met him a few times... Anyway, I have an impression. I know that he is a student of our school, so I didn't even ask him for his student ID card and just gave him the bill for the student meal..."

"Isn't that right? Come and look at the map. Chen Diancheng is a graduate student of Professor Ning Wei. He usually attends classes at the International Mathematics Research Center, which is almost at the northernmost part of the campus. I want to have a cup of coffee in your cafe. From Xiuchun Exit the road and walk 100 meters west, take the alley through the north gate of Tizai and go around to the fourth floor of the red building, then walk 800 meters west to Jingchun Road, and then walk through most of the campus to the catering complex."

"Come on, come on, look at the map for yourself to see how far it is going to go. How many places are there in the middle where you can drink coffee and eat bibimbap? What? Do you really think that the coffee in the most beautiful time is the best? You go here Isn't it because the most beautiful time in a coffee shop is very close to our college and dormitory? So do you think this coffee shop can really make an academic person with such a tight schedule come here every day? "

After hearing this, the little cute Momo in the dormitory had nothing to say. She was stunned, and then suddenly rushed towards the balcony...

"Hey, Momo, what are you going to do?"

"Oh, I need to look in the mirror... It's so unexpected... If it's really like what you said, how bad is this Chen Diancheng's vision!"

"Pfft... Haha... Momo, girls will have this day sooner or later, don't be shy!"

"That's right, be confident, you two are a good match!"

…

In the classroom of the International Mathematical Research Center, Chen Diancheng did not know that a formula he posted on impulse under the influence of hormones had already allowed several roommates in the female dormitory of the School of Journalism and Communication to use the analytical techniques used by Holmes to analyze his little thoughts. Everything was analyzed clearly...

He even felt quite proud.

Look, when the two met on the first day, it didn’t matter that Wen Yimo couldn’t understand such a post on WeChat Moments, and it didn’t even matter that she didn’t see it. But if the two of them get together in the future, when he proposes to him, he will find out the content recorded on WeChat for the girl, and then affectionately tell this stupid woman that he has been in love with her since the first day they met. I chose her...

This represents the fidelity of love...

Tsk tsk tsk...

Just thinking about it gives me goosebumps all over my body.

It's just too disgusting...

But it fits the romance of a science student. Chen Diancheng even thought about the scene when he proposed. He took out his mobile phone, found this circle of friends, and while the girl was looking at this circle of friends, he handed the prepared flowers to the girl. He went over and said affectionately: "Did you see that this love was destined by a mathematical formula on the day the two of them added WeChat, so marry me."

Well, a very simple proposal...

As long as he thought of this scene, Chen Diancheng felt inexplicably cheerful, and even the research materials in front of him that were originally difficult to chew became particularly pleasing to the eye. The only thing that bothers Chen Diancheng now is probably why he should ask Momo out for the first time to enhance their relationship?

…

The classroom where Chen Diancheng is located is about 45 degrees away from Ning Wei's office.

Ning Wei, who had just finished reading a bunch of research materials, rubbed his eyes and stood up to go home.

The laser generator to be used at the opening ceremony of the Olympic Games was determined after thorough calculations in March, and products from Raycus, a domestic brand in Jiangcheng, were selected. However, because the products needed this time are quite special and need to be specially customized, the Olympic Opening Ceremony Preparatory Committee has already placed an order, and the manufacturers are also working overtime to produce them.

Speaking of this order, there is another interesting fact.

I heard that these lasers were produced for the opening ceremony of the Olympic Games. The manufacturer took the initiative to provide these products for the opening ceremony absolutely free of charge. Chen Wenwen also decided that he would give some close-ups of Raycus' LOG at the opening ceremony. .

It's a typical win-win situation, which is pretty good.

So Ning Wei, who should have been very busy, has been free recently and just took time to read some books and materials recommended by Professor Pan. My life has been quite pleasant recently. After I made up my mind to change my direction, I felt that the sky became bluer. The happiness and joy of changing from research to re-learning is something that most people cannot experience.

After walking out of the office, he glanced at the classroom opposite with the lights still on, and then took two steps towards the corridor. Liu Wei also walked out of the door.

"Brother Liu, what a coincidence..." Ning Wei, who was in a good mood, joked casually.

Liu Wei rolled her eyes at Ning Wei, then followed Ning Wei, and said calmly: "Well, it's a coincidence. By the way, Xiao Chen is in love."

"Xiao Chen? Chen Diancheng? Is this kid in love? Finally one of my students is enlightened? Wait, how did you know?" Ning Wei looked interested and looked at Liu Wei sideways and asked.

"You, a student, caused a lot of trouble a few days ago, and the safety aspect is not very reassuring. Anyway, we at school have nothing to do, so we took care of him by the way."

Liu Wei explained, and then emphasized: "Besides, if he falls in love in a big way, the whole world will know about it. Isn't it strange that I know?"

"Oh...really?" Ning Wei glanced at Liu Weiwei, feeling that this guy was insinuating something.

After all, when he chased classmate Jiang, it was so spectacular that the whole world knew about it. The media in Europe followed the report for a while. After it reached China, God knows how many people were on the roster of Yanbei University, guessing who Jiang was...

Recalling that time, Ning Wei felt very sad.

"Haha... Two-thirds of the people in Ningshe were mobilized to form a foodie group just to coax other girls into the group. Oh, by the way, today he had a meeting with Cao Lin, chairman of Xingyu Group We meet and discuss business in the shop where that girl works, is she really your student?"

"Part-time job? Work-study program?"

"Not counting the work-study program, that girl's family situation is different from Xiao Jiang's. Her father is the leader of the Yuzhou Engineering Corps Command College, and her mother works in the local tax department. Working in a coffee shop is a way to experience life."

"That means this girl has a good temper. She's from our school?"

"Nonsense, a sophomore in the School of Journalism and Communication."

"I'll go, you guys are really efficient. My student was in love, and that night you figured out all the girls' situations..."

"Otherwise? What if a girl has a problem? It's not like you don't know. Wait, you don't seem to care about Chen Diancheng meeting the chairman of Xingyu Group?"

"Why do you care about such a trivial matter? You have to believe that today's young people, Diancheng is still very capable. He must have his own ideas on how to deal with the aftermath of this incident. He manages Ningshe very well, and I see that they have recently The plan to promote Ningshe is also very high-quality, so there is nothing to worry about. What’s that girl’s name?”

"Wen Yimo."

"Well, what do you think of Chen Diancheng in this article?"

"...I'm not a girl with roundworms in her belly, how do I know?" Liu Wei replied angrily.

"Hey... no, Brother Liu, I was just thinking. When I was chasing Xiao Jiang, Director Tian was very helpful. Now that I am a tutor, shouldn't I also be able to help my students?"

"..."
