Chapter 946

Back home,

Xu mang searched for the program "my father Xueba" in a hurry. He never thought that it was a serious science popularization program. Although it turned the popular science form into a question show, it had to be said that some of the contestants invited were too famous.

Professors, scholars and experts are all in normal operation. Even young academicians of the Academy of sciences are invited to attend. This really surprised Xu mang. However, in the accident, Xu felt that it was very humiliating to attend such a program.

"What's the matter?"

"With the cell phone... Face wrinkled." Yang Xiaoman took a look at her husband and calmly asked, "what are you studying? When can you stop this day? By the way, I'd like to drink sugarcane juice, which is freshly squeezed

"..."

"where can I get sugarcane for you?" Xu gave a blank look and said in a bad breath: "there is a watermelon in the middle of the refrigerator... You cut it in half, and then I and you are one and a half, and don't look at the present time, what sugarcane do you want to eat... I'll go through to buy you sugar cane?"

"Hum!"

"Don't you study relativity and quantum mechanics?" Yang Xiaoman, with a small mouth and a buttock sitting beside Xu Mang, said seriously: "I remember you said... There is a concept of space-time travel in relativity theory, which is what you said yourself."

Indeed,

Xu mang remembers telling Xiaoman that the concept of time-space travel was based on the high-speed rail as an example to calculate the possible time progression after taking the high-speed rail, but... This is only a theoretical existence.

"Wife?"

"How about I give you a test?" Xu said seriously: "I think your IQ has changed again recently... Really... Smart people. If you are willing to accept the IQ test, then I promise you to travel."

At first, Yang Xiaoman didn't want to accept the so-called IQ test, but she wanted to travel to relieve the pressure on her shoulders, and finally agreed to Xu Mang's proposal.

Xu mang took a look at his wife, glanced at the mobile phone in her hand, and then asked: "eh? Where's your cell phone? "

"Eh?"

"Cell phone?"

Yang Xiaoman was stunned for a moment. He crazily searched for the mobile phone with his mobile phone. He was anxious to find it, either turning the sofa or turning the kitchen. As a result, he didn't find the mobile phone. He was flustered and called out to Xu Mang: "it's over... I lost my mobile phone!"

"There are a lot of business partner's numbers on it, as well as some internal documents of the company. If this is lost, I will lose a lot of money!" Yang Xiaoman remembers that his face is red: "how to do? What should I do? Do you want to call the police? "

"Well!"

"Call the police immediately!" Xu mang cooperated with the performance and said earnestly, "call the police now!"

"Well!"

The next second,

Xiaoman picked up her right hand and started to call the police. As a result, she was very confused. Looking at her mobile phone, she was lost for a moment. This... Doesn't feel right? How does this mobile phone appear in your hand?

"Ha ha..."

"and said that I have a high IQ." Xu mang said with a smile: "look at you, this fool... Does your wife admit that he has a problem with IQ? Take a look... Look around with your mobile phone. If you can't find it, it's urgent... But don't worry, this kind of operation is normal. "

"..."

"Xu mang!"

"Believe it or not?" Yang Xiaoman was so angry that he gritted his teeth and yelled angrily: "you are clearly the inducement of language. You have deceived me in consciousness, hypnotized me, and made me have the illusion of losing my mobile phone!"

"Hum!"

"Don't make excuses!" Xu mang shrugged his shoulders and calmly said, "there is no way... The child has taken away half of your IQ."

"Go away!"

Yang Xiaoman wrung Xu Mang's waist meat, then sat down on the sofa and began to play with his mobile phone. He said, "are you really going to participate in the program" my father Xueba "? If I go, I'll give the program a call. "

Xu Mang:???

What's the situation?

She knows the people on the show?

"How do you know that show group?" Xu mang curiously asked: "you... You should not have registered secretly?"

"Not so much."

"I know the director of that program group. I'm a very good female director." Yang Xiaoman said: "do you have any idol burden? You are not a star. What's the burden? Besides, you can improve your popularity by participating in this kind of educational science program. "

"Go

"It's no fun staying at home anyway... Why don't you join us?" Yang Xiaoman began to whisper: "I will always be with you..."

Xu mang fell into silence, thought carefully for a long time, put forward his own worry, and said: "if I go, isn't this crushing? Losing the antagonism of the program has affected the balance between the playersHearing Xu Mang's words,

Yang Xiaoman gave a white look and said with disdain: "do you think you are really powerful? They are not vegetarians. They are all a group of people engaged in scientific research. Why are you invincible when you go? "

In a word,

Yang Xiaoman found some topics in the program "my father Xueba".

"Excuse me!"

"Why can't the bicycle fall down?" Yang Xiaoman asked.

Xu Mang: ∑ ('д′ * ノ) ノ

what?

This historical problem is actually the problem of this program?

What kind of Fairy Show is this?!

Why can't the bicycle fall down? This problem belongs to the unsolved mystery. Newton mechanics has been for more than 400 years now, and has not solved this puzzle. At present, the two possibilities are gyro force and centrifugal force.

Gyroscopic force means that a gyroscope will not fall down as long as it rotates. Here, the conservation of angular momentum is used. However, it is difficult to change the total angular momentum of a gyroscope by external torque after rotation, and it will not topple under slight disturbance.

As for the centrifugal force... Because the bicycle has speed, at the moment of falling down, because the tap can turn, at the moment of falling down, a local circular motion is formed. At this time, the speed will produce instant centrifugal force, which is opposite to the trend of bicycle falling down.

From a macro point of view, both concepts are conservation of angular momentum...

of course,

of course,

this problem has not been solved for more than 400 years, which is impossible to be so simple... Xu mang has not done systematic research, and other scientists should have conducted corresponding tests for a long time, proving that these two possibilities are wrong.

"What's the matter?"

"Don't you know?" Yang Xiaoman disdains to say: "still crazy not crazy?"

"..."

"I was wondering if I could use my super quantum computer to do simulation calculations." Xu mang frowned and said seriously: "the differential equation of Analytical Mechanics... To explain the problem that the bicycle does not fall."

After a few seconds of thinking, Xu Mang's eyes suddenly glowed with knowledge seeking light and said with a smile, "it's a little interesting!"

Yang Xiaoman:???

What's the situation?

Is this going to be a demon again?

"Hello, Hello, Hello!"

"You give me a break!" Yang Xiaoman said angrily: "don't go to study this broken problem. Now we're talking about participating in the program" my father Xueba ". Don't give me a topic."

"Oh..."

"it's OK to attend." Xu mang nodded and said seriously, "you can attend... But you can't let others know it's me."

"..."

"OK!"

"Because a lot of people have the same idea as you. After all, all of us have a head and a face. If we fail, it will be embarrassing." Yang Xiaoman said seriously: "so it is allowed to wear masks and use a fake identity to compete. Even if you lose, it's not disgraceful. Of course... Announce your identity before you leave."

"But a lot of people didn't make it public." Yang Xiaoman said: "my husband... Join us!"

After thinking for a moment, Xu mang finally nodded. Then he watched Yang Xiaoman call happily. At this time, he suddenly realized that the little star he had met on the plane said whether they had solved the NP problem completely?

"Hello?"

"Sister Ouyang?"

"My husband finally agreed to participate." Yang Xiaoman excitedly said: "yes, yes, yes... But he hoped that the program group would not disclose his information. Oh, no way. My husband is a great scientist after all, and his level is not low..."

"Well!"

"Good!"

"So fast?" Yang Xiaoman was stunned for a moment and said anxiously, "will the day after tomorrow begin? This... It's not ready. "

"How to say..."

"my husband... Should have no problem." "We'll come in the morning the day after tomorrow," Yang said seriously

PA,

hang up.

Yang Xiaoman embarrassed said: "husband... Time is more urgent, you will go to the program the day after tomorrow."

Ah?

So fast?

Are you sure it's not a Latino?

Xu mang asked cautiously, "wife, is it necessary to be so anxious? Is there no one to attend? "What nonsense!" he said

"It's a big show... Most people can't take part in it." Yang Xiaoman gave a white eye and said seriously: "I tell you... This is not your personal glory, it is related to the future of the child, you should strive for a bit, as Xu Yang and Xu man's Xueba father, can't count down to go home first."

"Cut!"

"How about rolling?" Xu mang curled his lips and said with disapproval: "I'm kidding... I was the top one in Zhejiang Province's college entrance examination."As a result,

Xu mang picked up his tablet computer on the tea table and began to study the last season's questions. At first, he thought that the program was an intellectual contest. As a result, he was totally wrong. This was a program that was biased towards academic questions.

The five judges are all big men in the scientific research field, and they are all famous people. The key is that they all know each other!

"Ah?"

"I know all these judges!" Xu mang pointed to the five scientific research leaders of the program group and said with a smile: "almost all of them have cooperated. Before, these people dare not speak in front of me. Unexpectedly, they became judges."
