I Don’t Want to Win Lying Down

This call is about the news that the Taibai Mao Mars landing rover is about to go to space. There is still about half a year to go. In January next year, the Taibai Mao Mars rover will go to the sky. It needs to fly in space for several years before reaching the surface of Mars.

think about

It's so far away!

After Xu Mang hung up the phone, he slumped silently on the sofa. He glanced at the current stock market. At present, it has fallen sharply, but this woman, Xiaoman, violated her original promise. Withdrawal, the result still depends on not getting out in the stock market.

At present, the United States has made preparations to rescue the market, and it should usher in a sharp rise, but Xiaoman doesn't take it seriously. This is just an expectation, and the phenomenon of diving will happen soon, let alone Xiaoman is really awesome!

The three major U.S. stock indexes opened higher across the board, and then fluctuated downward, diving in late trading.

This bitch has plundered a lot of money from others. Although I don't know how much she has earned, judging from the way she speaks, she has earned a lot, so much that it is impossible to estimate. Of course, this little money is in some financial families. In front of him, it's still not enough to see.

After all, in this world turmoil, it is not just Xiaoman who is making money alone, but many people are crazily cutting leeks together.

Hello?

roll!

Snapped!

Xu Mang hung up the phone directly, and actually wanted to watch the show. The show was so big. At this moment, Xu Mang was very angry. Xu Mang went out with the title four times. It seemed that he needed to do something to offset the negative effects of committing suicide by swallowing dung. Effect.

do what?

I don't know this!

But I'm too lazy to move, and wait until the baby is born. This stage is Xiaoman's most emotionally unstable stage, and try to stay by her side as much as possible.

After thinking about it, Xu Mang put it on, took the car keys, and went to the nearest square. Since he is a father-to-be, he must take up his father's responsibilities, buy some toys for the child, and do some moral, intellectual, physical, and aesthetic work. developmental toys.

Chenxi?

Do you have the time?

Would you like to go to the mall with me? Buy some toys for your nephew and niece, um, take Xiao Qiong with you.

Xu Mang sat in the driver's seat, touched his wallet, and said seriously: By the way, just come over with the two of you.

moment,

Xu Mang waited for Chen Xi's young couple in the coffee shop, and Xu Mang was very happy to see the two people who were busy in the world, which showed that Xu Yang and Xu Man still had a very high status in the hearts of Chen Xi and Xiao Qiong. Yes, but this is also related to himself and Xiaoman.

elder brother?

Why did you suddenly propose to buy toys for the child? Sitting across from Xu Mang, Chen Xi asked curiously, I just don't understand what's going on?

Get ready.

When are you two going to have a baby? Xu Mang took a sip of his coffee and asked curiously, It's almost there, right. There's something I need to discuss with you. Remember to pay for me. Don't forget.

as expected,

It's no good to ask yourself to be sure, because you didn't bring any money.

elder brother?

Sister Xiaoman has earned so much money, why didn't she give it to you? Xiao Qiong asked in confusion: I asked my father, and he said that this time the stock market crash in the United States suffered heavy losses, and those short sellers A lot of benefits have been gained.

Although I made a lot of money, I didn't take it out. I don't know what's going on with you, Xiaoman, and I still plan to earn some more. Xu Mang shrugged and said calmly, I have enough to buy vegetables now. Life is pretty tight”

grocery shopping?

Your grocery shopping is probably tens of millions, right?

Chen Xi didn't believe Xu Mang's nonsense. He had been cheated by him all the time in high school, but let's forget it this time. After all, he bought toys for his future nephew and niece, not to mention how expensive toys can be.

However

Unexpectedly, things are not so simple.

The main store of Lego bricks in Shanghai is also the largest Lego store in the country. Xu Mang is talking to the store manager about buying ten sets of Lego bricks. Unexpectedly, the store manager from abroad admires Xu Mang very much and agrees to his request without hesitation. .

What?

A complete set of Star Wars building blocks?

Chen Xi knows the pitfalls of Lego blocks, and also knows that the most valuable ones are the blocks related to Star Wars. I heard that there is a set worth more than 40,000 yuan. Good guy Xu Mang bought the whole set at once. Who is this toy for?

elder brother?

Are you buying toys for yourself? Chen Xi frowned, and said cautiously: Actually, I don't care. It will cost hundreds of thousands at most. How do you explain to Sister Xiaoman? Are you not afraid of being beaten to death by her? ?”

cut!

I'm already invulnerable to all poisons. Xu Mang shrugged and said calmly, Pay the money now!

swipe card,

Then I gave an address, and the store will send someone to deliver the toy to the home, and then the three of them went to eat, a fairly high-end barbecue restaurant.

Brother Xu Mang?

Do you know the n queens problem in chess? Xiaoqiong asked curiously.

have no idea.

Why did you ask this all of a sudden? Xu Mang was eating barbecue, and said with a blank face, What's the n queen question?

that is

Place eight queens on an eight-by-eight chess so that they cannot attack each other, that is, any two queens cannot be in the same row, column or oblique line. How many ways are there? Xiao Qiong Said: On a twenty-five-by-twenty-five chessboard, there are more than two billion possibilities.

oh

So that's how it is. Xu Mang suddenly realized, thought carefully, and said seriously, If I didn't misunderstand, is it impossible to solve the problem of twenty-one queens in the classic mathematical algorithm?

Hearing Xu Mang's words,

Xiao Qiong showed a frightened expression, and said in surprise: You know?

have no idea.

I can figure it out. Xu Mang smiled, I won't tell you how to calculate it, because you don't understand anyway.

Xiaoqiong suppressed her surprise, thinking that she was still too young. After all, she was standing in front of a world-class physicist, omniscient, omnipotent, and any unbelievable things were taken for granted in front of him.

Our school is currently studying the n queens problem. Xiao Qiong said, Actually, I also heard from hearsay. A professor in the physics department thinks that quantum physics can solve the queen's mystery.

Xu Mang was stunned for a moment, and soon he understood the reason why he did this. It may be that the interaction between atoms is used to make the atoms become chess queens. They act according to the rules of chess, that is, on the chessboard. Dodge each other in all directions.

good!

This method is interesting!

Xu Mang pondered for a moment, then said seriously, Did you bring paper and pen?

Bring it!

Give it to me, Xu Mang said.

oh.

moment,

Xiao Qiong then took out a notebook and a black pen from the bag, as she was a part-time job in Xiaoman's company, these two things were always ready in the bag.

After getting the paper and pen, Xu Mang wrote some very complicated formulas on it, and these formulas are all about quantum mechanics to solve the Queen's mystery. In this method, one problem needs to be considered first. The repulsive force of particles requires a Apply the device along the direction of motion to produce it.

What is this device?

second

Because there are so many possibilities, it will take a very long time, so it is crucial how the atoms cool down very quickly and allow their quantum properties to work.

Give!

Sometimes, hand over what I wrote to the physics professor at your school. Xu Mang said with a smile, This is some advice I gave him.

ah?

Xiaoqiong took the notebook that Xu Mang handed over with a look of panic. Although she didn't know what was written on it, it was densely packed with a large number of mathematical formulas, and there were a few paragraphs of text that were difficult to read, but this was Academician Xu Mang's suggestion , one can imagine how precious it is.

elder brother?

Can I make a copy and give the copy to someone else? Xiao Qiong said with a smile: Your original manuscript is too precious! Once Einstein's manuscript was excluded from a sky-high price, I think fifty years In the future, my manuscript will also sell for a lot of money.”

No need. Xu Mang smiled wryly.

after dinner,

Xu Mang went home, and secretly put the toys he bought in the warehouse in the basement.

half past four in the afternoon,

I drove to Xiaoman's company and brought some delicious meals along the way.

Is it tasty?

You can eat more if it's delicious. Xu Mang sat next to Xiaoman and said with a smile, I've been busy for a long time.

Go shopping for toys this morning? Yang Xiaoman glanced at Xu Mang and asked calmly.

Well?

How do you know? Xu Mang was stunned for a moment, then said in a low voice, I bought some for the children to play with.

snort!

Xiao Qiong posted on Moments, saying that she would buy toys for her niece and nephew. Are you and Chen Xi the two people in front of you?

It's a good thing that you have a conscience and know how to prepare in advance. You won't be at the company when you go home today. Yang Xiaoman said softly, By the way, let's see what toys you bought for your child.

Xu Mang: (￣△￣;)

It's over!

It's all over now!

back home,

Accompanied by Xu Mang, Yang Xiaoman came to the basement of his home, but when he saw the box in front of him, it exploded instantly.

(￣e(￣)☆╰╮o(￣dish￣) kill you!

Jiaotong University,

Xiao Qiong contacted a senior student who was a graduate student in the Department of Physics and happened to be in a certain professor's team.

Little Joan?

Why did you suddenly think of me? This senior has a good relationship with Xiao Qiong. The two are members of a club, and they usually communicate with each other.

Hee hee~

Of course I miss you. Xiao Qiong said: By the way, senior sister asked me to bring a letter of recommendation to the professor in your team, can you pass it on to him for me?
