I Don’t Want to Win Lying Down

Professor Angus rushed to the scene with a group of first-year mathematics majors. Everyone was a little curious. What is the so-called shocking picture? Could it be finished?

moment,

A group of people stood in front of the blackboard, the expressions on their faces were nothing but shock.

...

...

...

The students looked at the above content, it was a blackboard full of more than 20 yuan, let’s not mention the whole process, right? Just seeing this picture makes people feel suffocated. There are actually people in this world who are willing to do such a thing. topic.

One, two, three... twenty-two! A student carefully counted on the blackboard with the calculation process, and finally determined the number at twenty-two.

wrong!

Sudden,

A boy thought of something, rushed to a certain blackboard, and shouted: I remember when I saw that mysterious man just now, he seemed to be writing on this blackboard, which is the content of this blackboard. In the past seven or eight minutes, just... just finished writing twenty-two yuan?

After the student reminded,

Only then did almost everyone realize the seriousness of the problem. Indeed, when they saw the mysterious man, he seemed to be writing the content in the middle. I can’t remember exactly which part, but it was in the middle...

Annie!

Play the pictures you took, let's compare them. A certain boy shouted.

Subsequently,

Under the iron-like evidence, all the students are almost certain that when they saw the mysterious man, he was writing on the twelfth blackboard, and it turned out that less than ten minutes later, he finished all writing, so according to this speed , only took twenty minutes from start to finish?

Is this a devil? Twenty minutes... ordinary humans can't have such a speed?

Oh my God...

God...did I see a miracle?

He's an alien!

Everyone was shocked by the speed of this mysterious man,

This completely violates the limit level of human cognition, but... many people understand that the other party is a human being, not a demon, nor God's help, and it is even more impossible to be an alien.

Scribbled?

It doesn't look like scribbling... The handwriting is very clear, and the whole problem-solving process is very neat, not like random graffiti.

professor?

Is...is this right? one student asked.

Professor Angus remained silent throughout the whole process. He didn't want to comment too much on the mysterious man's speed. At this time, he heard a student's question and said seriously: This question... I don't know for the time being. After all, I It's not the questioner, only when Professor Mu comes, can we know the answer.

In fact, Professor Angus has this ability, but it's too time-consuming... It's better to ask the person who made the question to check it.

at the same time,

Xiaoman and her cousin are visiting a certain top luxury clothing store. For Yang Xiaoman, he has always been used to being extravagant. As long as it is what he likes, even if the price is sky-high, I'm sorry... I have to take it it!

not long,

Xiaoman spent more than 200,000 U.S. dollars, just buying a few clothes, and the average cost of each piece was 50,000 U.S. dollars.

Little Man?

Are you always so extravagant? Cousin Xiaoman witnessed her cousin's ability to spend money, and couldn't accept such a persona for a while. In her impression, her cousin shouldn't spend so much money. She should be a fairy, The kind that doesn't eat fireworks.

But...

After falling into the mortal world, a fairy becomes vulgar, so she knows how to spend money and spend money...and her spending power is stronger than that of ordinary people.

Yes!

What's the matter? Yang Xiaoman sat on a chair in a roadside restaurant, took a sip of a drink that cost three hundred dollars inexplicably, and said calmly: The main reason is that the speed at which Dad makes money far exceeds what I can spend money on. Speed, if you don’t use it hard, you won’t be able to spend it in the future.”

Whoops...

What a refreshing idea!

The cousin was very helpless towards Xiaoman, who was created by this person, but she attributed the culprit to Xu Mang. This guy must have brought her cousin down.

but...

Uncle is really good at making money, according to the current speed of spending money Xiaoman, far behind the speed of making money uncle.

Where's your husband? My cousin drank the same 300-dollar drink and asked curiously, Your husband spends money at the same speed as you?

No.

The most expensive thing he ever bought was a Porsche garbage truck, without even an air conditioner. Yang Xiaoman tilted his head and said, It seems... It cost more than four million at that time, and this was the only time he spent a lot of money , and the rest are small troubles, buying motorcycles and the like, it doesn’t cost a lot of money.”

That's pretty good. The cousin nodded, and said seriously: Although it looks a little... but overall, he is a family husband.

home type...

Ghost family type.

Yang Xiaoman has ten thousand reasons in his heart to refuse to admit that Xu Mang is a family type, but in front of his cousin, he still needs to pretend to be very happy, otherwise he will be looked down upon by her.

Little Man...

Your husband seems to be very talented in mathematics, right? My cousin suddenly asked an irrelevant question.

ah?

Uh...how should I put it? Yang Xiaoman said seriously: At present, it seems that apart from some century-old problems, the others should not be a problem, but this guy doesn't seem to like studying mathematics very much, which may be related to his being in physics. , doesn’t it mean that physics and mathematics are inherently hostile.”

this...

I don't like studying mathematics, but I have such a high talent in the field of mathematics...

Just jealous and envious!

Cousin Xiaoman was quite speechless. There was no need to guess about her own question. Xu Mang would definitely solve it. There was no suspense...

At this time,

My cousin received a call from my school colleague, Professor Angus.

Professor Mu!

The questions you gave the students were solved. Professor Angus said.

untied...

yes!

Be untied!

Cousin Xiaoman was about to speak, when she suddenly realized, how long has it been? In less than an hour...at most half an hour, it was...untied? Although it is not that difficult, the point is that the process of solving the problem is quite complicated.

Even if you are very talented, it will take an hour and a half, right?

Professor Angus!

Do you know how much time he spent? Cousin Xiaoman asked.

twenty minutes!

...

I'm sorry, Professor Angus. Cousin Xiaoman was stunned for a moment, then hurriedly asked: Can you tell me again, I didn't hear clearly just now.

twenty minutes!

I solved the problem in 20 minutes. I don't know the correctness for now. I hope you can take a look. Professor Angus said.

this...

This is simply unimaginable!

How could it be possible to solve everything in twenty minutes!

good!

hang up the phone,

Cousin Xiaoman froze in place stupidly. At this moment, she looked up at her cousin and said seriously: Xiaoman...call your husband and ask him where he is now.

ah?

He... isn't he solving a problem? Yang Xiaoman asked curiously.

Solving the problem... Cousin Xiaoman looked at the time and said helplessly: Your husband solved my problem fifteen minutes ago, now... I don't know where I went, You'd better give him a call, in case he gets lost, it's over.

this...

Forget it,

Ma'am, I'm used to it.

Yang Xiaoman didn't react too much, but she was worried about the safety of college students. According to her fiancé's urination, he must have sneaked into the place where other people are in class, and it is the classroom with the most people. He is probably sitting in the corner now , looking for an opportunity.

I made a call, but was hung up by the other party as soon as I got through.

at this time,

Yang Xiaoman has already collapsed.

What's wrong?

Your husband doesn't answer your phone? asked the cousin.

Well...

Sister...let's ignore that idiot, what do you want to do now? Xiaoman asked.

go back!

I'm going to see Xu Mang's problem-solving process, whether it's right or not, Cousin Xiaoman said.

...

for a long time,

Xiaoman and her cousin went back to Columbia University together, and immediately saw the topic. Xiaoman thought it was just a few simple processes, but she was not shocked when she saw the contents of the twenty-two blackboards.

How should I put it...belongs to basic operations!

Domestic students and teachers have become accustomed to it, it's time to shock foreigners, and they won't be shocked to death!

this...

It was completed in half an hour? My cousin couldn't accept the facts in front of me for a moment, just kidding... The content of the twenty-two blackboards only took about twenty minutes. Is he God?

Professor Angus!

This... Are you sure this was done in twenty minutes? Cousin Xiaoman asked with a look of horror.

I don't know either.

However, the students encountered a problem solver on the way to class, and a student took a video. Based on this video, we calculated the specific time, which was about 20 minutes. Professor Angus said.

Cousin Xiaoman completely trusts her colleague, and he will not lie about this matter.

Since it's so fast,

Then there must be an error in the content!

After all, speed and quality are inversely proportional, the faster the speed, the worse the quality.

The cousin began to carefully review Xu Mang's problem-solving process. Although there were many people around, it was very quiet at the moment. They also wanted to know whether the process was correct, and the students also tried to check the problem-solving process.

Think about it later... Since Professor Mu will come, wouldn't it be better to wait for the result?

five minutes,

ten minutes,

twenty minutes...

finally,

Xiaoman's cousin reviewed Xu Mang's problem-solving process. She has been completely conquered by the beautiful mathematics. In her eyes, there is no more beautiful number in the world than this. This is the first time she has seen such a simple process.

Even more perfect than my own answer!

Professor Mu?

Is...is this right? a student asked curiously.

...

Although I don't want to admit it...but the problem-solving process is more perfect than my answer! Cousin Xiaoman sighed and said helplessly: It's amazing...

words fall,

It caused an uproar in the audience.

Everyone is looking for an answer,

Who is this heaven-defying mysterious guy?

You must be guessing who this person is? Cousin Xiaoman looked around and said with a smile, I already know who he is.

???

???

???

Hearing Professor Mu's words, the people present looked at her intently.

Answer,

All are desperate for answers.

He is Xu Mang!

A professor of theoretical physics from Huaguo!

...

Brother,

Classroom of theoretical physics.

In the face of multi-particle systems, we generally use approximate methods to simplify physical problems under an appropriate model. A professor of theoretical physics is giving a lecture to first-year students, but a big gray dog ​​is mixed into the group of little sheep present. Wolf.
