Chapter 962: 1 letter of recommendation (one/three)

This call is about the news that the Taibaimao Mars lander is about to go to the sky, and there are about half a year away. About January next year, the Taibaimao Mars rover will go to the sky. It will take several years to fly in space before reaching the surface of Mars.
Think about
This is so far away!
After Xu Mang hung up the phone, he paralyzed silently on the sofa and took a look at the current stock market. At present, it is all about the level of a big drop, but Xiaoman, a woman who violated her original promise, just said 20,000 points. Withdrawal, the result still depends on the stock market.
At present, the United States has made preparations to rescue the market, and it should be ushering in a trend of rising. As a result, Xiaoman disagrees. This is just an expectation, and diving will happen soon, let alone Xiaoman is really awesome!
The three major US stock indexes opened higher across the board, then fluctuated downward, and dived late.
This girl has shaved off a lot of other people’s money. Although I don’t know how much she has made, she has made a lot of money from the aura of her words, which is beyond estimation. Of course, this little money is in some financial families. In front of it, it's still a bit not enough.
After all, in this world turmoil, not only Xiaoman is making money alone, but many people are cutting leeks together.
"Hey?"
"roll!"
Snapped!
Xu Mang hung up the phone directly. He wanted to watch the performance. He was very angry at the moment. Xu Mang's title of four times went out like this. It seems that something needs to be done to offset the negative caused by suicide by swallowing dung. effect.
doing what?
I don't know this!
But I didn't bother to move. I slowly waited until the child was born. This stage is the most unstable stage of Xiaoman's emotions, and I try to stay with her.
After thinking for a while, Xu Mang put on his car key and headed to the nearest square. Since he is a prospective father, he must take his father’s responsibilities and buy some toys for the child, some moral, intellectual, physical, and comprehensive 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, bring Xiaoqiong with you." Xu Mang sat in the driver's seat and touched his wallet, and said seriously: "That's right. Two people come over."
moment,
Xu Mang waited for Chenxi’s couple in the coffee shop. Xu Mang was very happy when he saw the two men in the dust. It shows that Xu Yang and Xu Man are still very high in Chenxi and Xiaoqiong’s hearts. Yes, but this is also related to himself and Xiaoman.
"brother?"
"Why suddenly proposed to buy toys for the child?" Chen Xi sat opposite Xu Mang and asked curiously: "I don't know what the situation is?"
"Be prepared in advance."
"When do you two have children?" Xu Mang took a sip of coffee and asked curiously: "It's almost done. Right, there are some things that you need to discuss. Remember to pay for me, don't forget."
""
""
as predicted,
There is no benefit to finding oneself, it turns out that there is no money.
"brother?"
"Sister Xiaoman made so much money, why didn't you give it to you?" Xiaoqiong asked in confusion: "I asked my dad. He said that the American stock market suffered heavy losses this time, and those short sellers Got a lot of benefits."
"Although I made a lot of money, I didn't take it out. Sister Xiaoman still doesn't know what the situation is, and I plan to make a little 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?
Chenxi didn't believe in Xu Mang's nonsense. He had been tricked by him before in high school, but let's forget it this time. After all, he bought toys for his future nephew and niece, and how expensive the toys can be.
however
Never thought that things are not that simple.
Mordu Lego Brick Store is also the largest Lego store in the country. Xu Mang is talking to the store manager about purchasing ten sets of Lego bricks. Unexpectedly, this store manager from abroad admires Xu Mang very much and agreed to his request. .
"what?"
"Star Wars full set of building blocks?"
Chenxi knows the pits of Lego bricks, and also knows that the most valuable piece of it is the building blocks of Star Wars. I heard that there is a set worth more than 40,000. The good guy Xu Mang actually bought a full set. Who is this toy for?
"brother?"
"Are you buying toys for yourself?" Chenxi frowned, and said cautiously: "Actually, I don't care. It costs a few hundred thousand at most. What do you say to Sister Xiaoman? Are you not afraid of being beaten to death by her? ?"
"cut!"
"I'm no longer invaded by poison." Xu Mang shrugged and said calmly: "Hurry up and pay!"
Swipe,
Then given an address, the store will send someone to deliver the toys to the house, and then the three of them will go to dinner, a fairly high-end barbecue restaurant.
"Brother Xu Mang?"
"Do you know the n queen problem in chess?" Xiaoqiong asked curiously.
"do not know."
"Why did you ask this suddenly?" Xu Mang was eating barbecue and said blankly: "What is the problem with Queen n?"
"Yes"
"Place eight queens on an eight-by-eight chess so that they cannot attack each other. That is, no two queens can be in the same row, column or diagonal line. How many ways are there?" Xiaoqiong Said: "If you are on a chessboard of twenty-five by twenty-five, there are more than two billion possibilities."
"Oh"
"It turned out to be like this." Xu Mang suddenly realized, thought about it, and said seriously: "If I didn't understand the error, is it impossible to solve the problem of twenty-one queens in classical mathematical algorithms?"
Hearing Xu Mang's words,
Xiaoqiong showed a frightened expression, and said in surprise: "You know?"
"do not know."
"I can figure it out." Xu Mang smiled, "I won't tell you how to calculate it. You don't understand it anyway."
Xiaoqiong put away her surprise and felt that she was still too young. After all, he was a world-class physics scientist who knew everything, omnipotence, and anything that seemed incredible to him was taken for granted.
"Our school is currently studying the n-queen problem." Xiaoqiong said: "Actually, I also heard from the hearsay that a professor in the Department of Physics believes that quantum physics can solve the queen's mystery."
Xu Mang froze for a moment, and soon he understood the principle of why he did this. This may be the use of the interaction between atoms to make atoms the queen of chess. They act according to the rules of chess, which is on the chessboard. Avoid each other in all directions.
Not bad!
This method is interesting!
Xu Mang pondered for a moment, and said seriously: "Have you brought paper and pen?"
"Bring it!"
"Give it to me" Xu Mang said.
"Oh."
moment,
Xiaoqiong took out a notebook and a black pen from the bag, as she was working part-time in Xiaoman's company, and she kept the two things in the bag at any time.
After getting 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, there is a problem that needs to be considered first. The repulsive force of particles requires a It can only be produced by applying the device along the direction of movement.
What is this device?
Second
Because there are so many possibilities, this will take a very long time, so it is crucial that the atoms cool down very quickly and make their quantum properties work.
"give!"
"Sometimes I submit what I wrote on to the physics professor of your school." Xu Mang smiled and said, "These are some tips I gave him."
"what?"
Xiaoqiong took the note book handed over by Xu Mang with a look of trepidation. Although he did not 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 the suggestion of Academician Xu Mang. , You can imagine how precious it is.
"brother?"
"Can I make a copy and give the copy to someone else?" Xiaoqiong said with a grin: "Your manuscript is too precious! Once Einstein's manuscript was ruled out for a sky-high price, I think fifty years I will also sell a lot of money for this manuscript in the future."
""
"No need." Xu Mang smiled bitterly.
After eating,
Xu Mang went home and secretly put the toys he bought in the warehouse in the basement.
4:30 in the afternoon,
I drove to Xiaoman's company and brought some delicious meals along the way.
"Tasty?"
"If it tastes delicious, eat more." Xu Mang sat beside Xiaoman and said with a grin: "I have been busy for a lot of time."
""
"Going to buy toys in the morning?" Yang Xiaoman glanced at Xu Mang and asked calmly.
"Uh?"
"How did you know?" Xu Mang was stunned for a moment, and said in a low voice, "I bought some for the kids to play with."
"Humph!"
"Xiaoqiong sent a circle of friends and said to buy toys for her niece and nephew, are you and Chenxi the two figures behind you?"
"You still have a conscience, knowing that you have prepared in advance, and you won't be at the company when you go home today." Yang Xiaoman said softly, "By the way, see what toys you bought for your child."
Xu Mang: (￣△￣;)
That's it!
This is all over!
Back home~EbookFREE.me~ Yang Xiaoman, accompanied by Xu Mang, came to the basement of his home, and when he saw the box in front of him, it exploded instantly.
(￣e(￣)☆╰╮o(￣ bowl￣)Kill you!
Jiaotong University,
Xiaoqiong contacted a certain senior sister, she was a graduate student in the physics department, and she happened to be in a professor's team.
"Little Joan?"
"Why did you think of me suddenly?" This senior sister and Xiaoqiong have a good relationship. The two are members of a society and they have exchanges in normal times.
"Hee hee~"
"Of course I miss you." Xiaoqiong said: "By the way, somebody asked me to bring a letter of advice to the professor of your team, can you pass it to him for me?"
