Chapter 962

This phone call is about the news that the Taibai cat Mars Lander is about to go to the sky. There will be about half a year to go. In January of next year, the Taibai cat Mars rover will go to the sky. It will take several years to fly in space, and then reach the surface of Mars.

Think about...

it's so far away!

After hanging up the phone, Xu mang quietly collapses on the sofa and takes a look at the current stock market. At present, it is the extent of the sharp drop. However, Xiaoman, a woman, broke her original promise and withdrew at 20000 points. As a result, she was still stuck in the stock market.

At present, the United States has made preparations for the rescue of the city. It is reasonable to say that it will usher in a sharp upward trend, but Xiaoman doesn't think so. This is just a kind of expectation. The phenomenon of diving will happen soon, let alone... Xiaoman is really strong!

The three major U.S. stock index opened high, followed by shock downward, diving in the end.

The girl scraped a lot of money from other people. Although she didn't know how much she had made, she made a lot of money from her manner of speaking. Of course, this money is not enough for some financial families.

After all, in this global turmoil, not only Xiaoman is making money, but many people are cutting leeks crazily together.

"Hello?"

"Go away!"

Bang!

Xu mang hung up the phone directly and wanted to see the performance. The performance was over. At the moment, Xu mang was very angry. Xu went out with this title four times. It seems that something needs to be done to offset the negative effect of suicide by swallowing feces.

What do you do?

This... I don't know!

But also lazy to move, slowly wait until the baby is born... Now this stage is the most unstable stage of Xiaoman's mood, try to accompany her side.

After thinking about it for a while, Xu mang took the car key and went to the nearest square. Since he is a father to be, he must take the responsibility of his father and buy some toys for his children, which are developed in an all-round way.

"Chenxi?"

"Do you have time?"

"How about going to the mall with me? Buy some toys for your nieces and nephews. Well... Bring Joan with you Xu mang sat in the driver's seat, touched his wallet and said seriously: "by the way... Just you two come here."

...

for a moment,

Xu mang waited for Chen Xi's couple in the coffee shop. When he saw the two people, Xu mang was still very happy, which showed that Xu Yang and Xu man had a high status in the minds of Chen Xi and Xiao Qiong, but... It also had something to do with himself and Xiaoman.

"Brother?"

"Why suddenly asked to buy toys for children?" Chen Xi sat on the opposite side of Xu Mang, and asked curiously, "I have a little wonder... What is the situation?"

"Get ready in advance."

"When do you two have children?" After taking a sip of coffee, Xu mang asked curiously, "it's almost OK... By the way, I need to discuss something with you. Remember to help me pay the bill. Don't forget it."

"..."

"..."

of course,

it is no good to come to your own place. It turns out that there is no money with you.

"Brother?"

"Little sister man has made so much money, why... Why didn't she give it to you?" "I asked my dad, he said that this time the U.S. stock market disaster suffered heavy losses, and those short sellers got a lot of benefits."

"Although I made a lot of money, I didn't take it out. I'm still in it. I don't know what's going on. I'm going to make a little more." Xu mang shrugged his shoulders and said calmly, "I have enough to buy vegetables now, and my life is very poor..."

buy vegetables?

I'm afraid you can buy tens of millions of dishes, right?

Chen Xi doesn't believe Xu Mang's lies. When he was in high school, Chen Xi was cheated by him all the time. But this time, let's forget it. After all, he bought toys for his future nephew and niece. Besides, how expensive can toys be.

However...

never thought that things were not so simple.

Mordo Lego building block headquarters is also the largest Lego Store in China. Xu mang is talking with the store manager about purchasing Lego building blocks. Unexpectedly, the store manager from abroad adores Xu Mang and agrees to his request.

"What?"

"Star Wars complete set of building blocks?"

Chen Xi knows the pit of Lego building blocks, and also knows that the most valuable one is about star wars. It is said that there is a set worth more than 40000. Good guy... Brother Xu mang has bought a complete set of bricks. Who is this for?

"Brother?"

"Are you buying yourself toys?" Chen Xi frowned and said cautiously, "in fact, I don't care. I spend hundreds of thousands at most. How can you account for that? Are you not afraid to be killed by her? "

"Cut!""I'm safe." Xu mang shrugged his shoulders and said calmly, "pay quickly!"

Credit card,

and then give an address, the store will send a special person to deliver the toys to the home, and then three people will go to dinner, which is a relatively high-grade barbecue shop.

"Brother Xu mang?"

"Do you know the n queen problem in chess?" Asked little Joan curiously.

"I don't know."

"Why did you ask that all of a sudden?" Xu mang is eating barbecue, a blank face said: "this n queen problem is what problem?"

"That is..."

"put eight queens in eight times eight chess so that they can't attack each other, that is, any two Queens can't be in the same row, the same column or the same oblique line. How many kinds of placement are there?" "On a 25 by 25 chessboard, there are more than two billion possibilities," said Joan

"Oh...

" so it is... "Xu mang suddenly realized, thought carefully for a moment, and seriously said," if I didn't understand wrong, in the classic mathematical algorithm... Can't solve the problem of 21 queens? "

Hearing Xu Mang's words,

Xiaoqiong showed a frightened expression and said in surprise, "you... You know?"

"I don't know."

"But I can work it out." Xu mang smile: "how to calculate don't tell you, anyway you don't understand."

After all, she is a world-class physics scientist, who knows everything and can do everything. Anything that seems incredible is taken for granted in front of him.

"Our school is studying queen n recently." "In fact, I'm also hearsay. A professor in the Department of physics thinks that quantum physics can solve the Queen's mystery," she said

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

Good!

This method is interesting!

Xu mang pondered for a while and said seriously, "have you brought your pen and paper?"

"Yes

"Give it to me..." said Xu.

"Oh."

After a while,

Xiaoqiong took out a notepad and a black pen from her bag as part-time job in Xiaoman company. She was always ready in the bag.

After getting the paper and pen, Xu mang wrote some very complicated formulas on them, and these formulas are all about the fundamental solution of the Queen's puzzle by quantum mechanics. In this method, we first need to consider a problem that the repulsion force of particles can only be produced by applying a device along the direction of motion.

What is this device?

Second...

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

"Here you are

"When I have time to submit what I wrote above to the physics professor in your school." Xu mang said with a smile: "this is my little advice to him."

"Ah?"

Xiaoqiong took over Xu Mang's memo pad with a look of panic. Although she didn't know what was written on it, a large number of mathematical formulas, and a few fragments of words that were very difficult to read, this was academician Xu Mang's suggestion. You can imagine how precious it is.

"Brother?"

"Can I make a copy and give it to someone else?" Xiaoqiong said with a smile, "your original manuscript is so precious! Once upon a time, Einstein's manuscript was shot at a high price. I think in 50 years' time, this manuscript will sell for a lot of money. "

"..."

"no need." Xu mang said with a bitter smile.

After dinner, Xu mang went home and secretly put the toys in the warehouse in the basement.

At 4:30 in the afternoon,

drove to Xiaoman's company and brought some delicious food.

"Is it delicious?"

"Eat more if you like." Xu mang sat on the side of Xiaoman and said with a smile, "I've been busy for a lot of time."

"..."

"did you go shopping for toys this morning?" Yang Xiaoman glanced at Xu Mang and asked calmly.

"Eh?"

"How do you know that?" Xu mang Leng for a moment, whispered: "buy... Buy a little, for children to play."

"Hum!"

"Little Joan made a circle of friends and said to buy toys for her niece and nephew. Are you and Chenxi the two figures in front of you?"

"Thanks to your conscience, you know to prepare ahead of time. I'm not in the company today." Yang Xiaoman said gently: "by the way, see what toys you bought for your child."Xu Mang: (￣ △;)

it's over!

This is all over!

Back home,

accompanied by Xu Mang, Yang Xiaoman came to the basement of his home. When he saw the box in front of him, he instantly exploded.

(~ ε) ~ system ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~!

...

at Jiaotong University,

Xiaoqiong contacted a senior sister, who was a graduate student in the Department of physics and was in the team of a professor.

"Little Joan?"

"Why did you suddenly think of me?" The elder sister has a good relationship with Xiaoqiong. They are members of a community and have communication at ordinary times.

"Hee hee ~"

"of course, I miss you." Xiaoqiong said, "by the way, sister... Someone asked me to bring a letter of advice to the professor in your team. Could you pass it on to him for me?"
