Pulse detonation engine announced for entry into the Air Force

Chapter 353: A conjecture that stumps the world, a mission under the Eastern Academy of Sciences!

"Have you done calculations like this before?"

The staff member couldn't help but raise her head and stared at Qin Xiao with a pair of eyes.

She didn't believe that someone could complete the mental arithmetic of 13th power in such a short time.

If this is a number within 10, those math masters can do it in a short time. Calculate it, but even if you are a master of mathematics, you can't just glance at it and know the answer in your mind.

It will take a few minutes at least.

Therefore, the questions here are not for ordinary people to answer. The goals are some mental arithmetic. Master.

For ordinary people to try, they are just looking for abuse.

The calculation process often involves dozens of powers. Let alone ordinary people, even mathematics masters cannot guarantee that they can answer the questions correctly every time.

Moreover, the answer is so Chief, sometimes it is extremely difficult to write down even if you get the answer right.

The staff member glanced at Qin Xiao's young face and shook his head in his mind. He must have done it before, otherwise there would be no way to do it. So fast.

On the side, Xia Qiange's eyes were wide open, with a look of disbelief on her face.

Mental arithmetic to the thirteenth power!

Is this... real?

And when she heard the staff's confirming words, her black eyes became even brighter. I couldn't help but shrink for a while, and the same thoughts as the staff came to my mind.

If this had not been done before with similar questions, it would be impossible for ordinary people.

Even if it is done by those mathematics masters Come on, I'm afraid I have to give up.

There is no rule for 17 to the 13th power. It really depends on mental arithmetic. Even if there is a good calculation method, such tedious calculation steps can make a person's brain confused. The computer immediately crashed.

On the side, the people who were watching were also shocked.

Let me go, mentally calculate 13th power?

No, this can be said to be 13th power calculation in seconds.

Just now, Qin Xiao I'm afraid I only watched it for less than ten seconds. Even if you include the time for writing numbers, I'm afraid it won't exceed 20 seconds.

Twenty seconds, let alone mental calculation of thirteen times, even if it is 17 to the third power, give This time is definitely not enough for ordinary people to calculate.

Is this still a human?

Is this really the speed that a human can achieve?

In less than twenty seconds, while mentally calculating 13 powers, he also wrote down the long list of answers. This kind of Things, let alone ordinary people, even math masters can't do it.

Where do these people come from? Are they so cruel?

A world-class math master hiding in the world?

They can't figure it out, but it doesn't stop them from being shocked.

Even further away, there are The man who hadn't walked far couldn't help but turn around when he heard the noise here. Seeing that someone had answered the question correctly, he couldn't help but drop the thing in his hand to the ground, and kept muttering in his mouth:"My heart."...Can you really do the thirteenth power calculation in your head in such a short time?"

"This is too scary!"

Who can complete the huge calculation of 17 to the 13th power in just ten seconds? Let alone the calculation, even if the answer is recited by one person, ten seconds is not enough!

This is so incredible. Terrifying calculation ability, and memory ability?

Memorization can be done, and many memory masters can do it.

But most people can't even think about complex calculations. Although mathematics masters have terrifying mental arithmetic abilities, they can't do it in such a short period of time. It is completely impossible to complete the mental calculation of thirteen powers in a short period of time.

This kind of person is a super master of mathematics!

Not far away, Wang Xiyue, who had just arrived, happened to see this amazing scene. In the eyes.

Mental calculation to the thirteenth power?

Real or fake?

No, can anyone really do the mental calculation to the thirteenth power in such a short time?

Even 2 to the thirteenth power takes a while, let alone The thirteenth power of 17, even some math masters couldn't complete the mental calculation in a few minutes, right?

She even doubted whether the math masters could mentally calculate the thirteenth power of this number.

As a top student at Tokyo Shin University, She still knows some basic common sense. To put it bluntly, many of the teachers and professors at Tokyo University of Science and Technology are bachelors or even bachelors from the Eastern Academy of Sciences. The mathematics department has a good reputation in the world. Mathematicians.

But even that group of people dare not say that they can mentally calculate 17 to the 13th power, and they still completed the mental calculation of 13th power in such a short period of time.

The others who followed Wang Xiyue took a long time to recover from their shock. When Qin Xiao realized what he was doing, they all turned pale with shock, their faces full of horror.

Damn it!

What the hell?

It’s up to 20 seconds, really up to 20 seconds, from the time Qin Xiao opened the note to the time he finished writing that sentence on the note. It definitely took less than 20 seconds to string together numbers.

Completed mental arithmetic to the thirteenth power in less than 20 seconds?

Is this guy... really a human?

……

However, just when everyone was shocked, the staff reminded everyone with one sentence.

Have you done this before?

At this moment, everyone suddenly woke up.

I have definitely done it. If I have never done this kind of problem, who can complete the mental calculation of thirteenth power in such a short time?

"Damn it, I was scared to death. I thought it was really calculating thirteen times in one second~."

"It turned out that it had been done before, so I was relieved. I almost thought there was a magic trick coming out of the thirteenth power."

"However, even if he has done it before, apart from the fact that he cannot mentally calculate the thirteenth power, can he still get the prize?"

"That seems to be the case. It depends on what the staff says."

……

Everyone suddenly realized and started chattering.

When Qin Xiao heard the staff's words, he shook his head helplessly,"I haven't done it before. I just made it just now."

Have you done it?

A chief designer who can independently complete the development of third-generation aero engines and fifth-generation fighter jets can do mental arithmetic to the thirteenth power. Isn’t this a basic skill?

Just made it?

However, what he said made the staff shake their heads inwardly after listening to it. However, he said:"I don't know whether you have done it or not. After all, it is difficult for me to say this kind of thing." I believe you calculated it mentally on the spot, but I can't prove that you have done it before, so I'll give you the prize, but I also have something to say.……"

The staff member paused, and suddenly a serious look appeared on his face:"It takes at least ten minutes for even some world-class mathematicians to mentally calculate 17 to the 13th power, and not every mathematician can do it. It’s easy to do, and you just took only twenty seconds from seeing the question to writing down the answer. If you were a world-class mathematician, I would still believe it, but……"

She didn't say anything else, but the meaning in her words was expressed very clearly.

That is, she does not believe that Qin Xiao can do mental calculations to the thirteenth power.

"I did the mental arithmetic on the spot.……"

Halfway through his words, Qin Xiao shook his head and stopped talking.

He also knew very well that if he said it now, it would be in vain and no one would believe it.

Seeing that Qin Xiao stopped talking, the staff felt that Qin Xiao could not continue editing. He shook his head and handed the packaged jade pendant to Qin Xiao without saying anything with a smile on his face:"The topic here is There aren't many people in the league who can answer the question within five minutes, so this jade pendant is worth a lot, so you should keep it."

Looking at the other party who looked like you were lucky, Qin Xiao also spread his hands helplessly..

However, there was no further explanation.

Anyway, I got the jade pendant, so let the other party think whatever they want. Is it possible that they still have to prove something? (To read exciting novels, go to Feilu Novel Network!)

"Thanks."

Qin Xiao thanked her and pulled Xia Qiange, who was trying to hold back her laughter, towards the academic competition.

Until she left, Xia Qiange couldn't help but feel a little happy.

She is also a student who graduated from a prestigious university. Although I am not majoring in mathematics, I am proficient in advanced mathematics. I have some mental arithmetic skills, but in terms of how strong I am, there is basically no hope for difficult numbers above the 5th power. Moreover

, In his school, he had seen the mental arithmetic abilities of some mathematics professors. He could still do difficult numbers below the 75th power, but he couldn't do it as fast as Qin Xiao.[]

Qin Xiao looked at him and rolled his eyes.

"I didn't expect you to be so boring before, and you would run to calculate 17 raised to the 13th power. But your memory is so good, you can remember a long series of numbers, which is really incomparable to ordinary people. Anyway, I can't remember it."Xia Qiange laughed.

Qin Xiao raised his hand and stroked his forehead,"I really just calculated it."

"Okay, my Air Force pilot comrade, you don’t have to be like this in front of me. They have given you prizes. Even if you remember the answer, they can’t say anything. They can only say that my big boy is so lucky. He can’t even do this. You can get the questions you have done."

Qin Xiao opened his mouth, forget it, no more explanation.

Anyway, no matter how much you explain, no one will believe it, let alone Xia Qiange, and no one else will believe it. If Qin Xiao didn't know his ability , I'm afraid he doesn't believe it himself.

It is impossible for others to believe something that he may not believe.

Seeing that Qin Xiao was speechless by what he said, Xia Qiange laughed and said,"Okay, I Isn’t it okay to believe it?"

Is this the expression of a letter? Qin

Xiao rolled his eyes. She was holding a jade pendant in her hand, with a smile on her face. Although it was not the first time that her beloved big boy gave a gift, it was the first time that it had a different meaning. Overflowing with joy, Xia Qiange walked forward, facing forward , while turning back and smiling at Qin Xiao. Qin Xiao followed, looking at the beautiful figure in front of him, squinting his eyes slightly. He liked it no matter how he looked, and never got tired of it. As for other girls who don’t believe in mental arithmetic He didn't care about the matter, and it didn't affect his appreciation of beauty at all.

……

The academic competition was held in the first stadium of Tokyo Shin University. The huge playground was crowded with people. Teams from various forces were separated in all directions. They were surrounded by isolation ropes. Many security guards and students of Tokyo Shin University were in charge. Order on site.

Fortunately, the quality of the people who came to watch the academic competition was pretty good, and it was not as noisy as expected. In fact, apart from the voices of various power teams talking, there were very few unnecessary sounds.

Even if the onlookers wanted to speak, they would do so in a soft voice and would not dare to make a loud noise.

On the one hand, it is not allowed, and on the other hand, it cannot be tolerated to interrupt this academic competition in full swing.

The rules of the academic competition are very simple. Each participating force prepares some mathematical problems in advance, and then other forces present propose solutions.

These problems have all been raised before, so they are not unprepared.

Otherwise, it would be impossible to just find a mathematical problem that no one has ever encountered and want to solve it on the spot.

When Qin Xiao and Xia Qiange arrived, the competition had actually reached its peak, and many difficult problems were solved on the spot by mathematicians from various forces.

However, since it is a competition, some people are happy and some are sad.

The forces that solve more problems will naturally have smiles on their faces.

There are relatively few problem-solving, and I have not even solved a problem yet, so I feel quite depressed.

However, overall, the atmosphere was quite good and there were not too many conflicts.

Academic exchanges do not involve too many conflicts. Everyone gathers together not to quarrel or create conflicts, but to solve problems.

When a difficult problem is solved, both the solver and the proposer are ecstatic.

Even some mathematicians who had nothing to do with their influence laughed heartily.

The more problems they solve during the academic competition, the fewer problems they will encounter in the field of scientific research in the future.

Those who can come to this academic competition are top mathematicians from various forces.

A group of top mathematicians is much stronger than a combination of one or two individuals.

One or two people may not be able to solve a difficult problem, but when a group of people come together to express their opinions, and through the collision of ideas, they can often come up with a brand new way to solve the problem.

However, this harmonious atmosphere was caused by a difficult problem presented by a mathematician from the Star Alliance, and his expression changed somewhat.

Somewhat ugly.

On the Eastern God Alliance side, Meng Xiuyun, the alliance's top mathematician, glanced at the Star Alliance's question board. The joy on his face instantly disappeared without a trace. The next moment, it became a little ugly, but He didn’t have a fit on the spot, but just frowned and said:"Professor Gray, this question has been asked for four or five years, and no one has been able to prove it yet. It’s boring for you to ask this question every time."

"Why don't we change the question? If this conjecture was proven, we wouldn't have to wait until today."

People from other forces were all lowering their heads and thinking about the problem. When they heard Meng Xiuyun's words, they couldn't help but look up at the Star Alliance board.

It's okay not to look at it. After looking at it, every The corners of one person's mouth couldn't help but twitch.

Someone couldn't help but mention:"Professor Gray, Professor Meng is right. Let's put it another way. This conjecture has been proposed for hundreds of years. I still don't have any clue. This It’s really unreasonable to take it out when the time comes (Good Li’s). Moreover, Professor Wang is right. As for this guess, how many times have you taken it out?"

"Gray, let’s change it. I know you have prepared other questions. This one……"Someone shook his head

……

Faced with everyone's persuasion, Professor Gray not only had no intention of changing, but shook his head and said:"It's not that I don't want to change, but this conjecture can't always be left like this, right? No one has proven it for hundreds of years, so we just Don't you want to prove it?"

"Originally, I didn't plan to come up with this problem, but I thought about it for a long time. While the world's top mathematicians are here, we have to solve it without eating or drinking. Is it possible to keep it for the next generation? Can't you prove it?"

"It doesn't matter to you, but I can't afford to lose that person."

Gray said these words loudly and righteously, as if he was doing it for everyone's good.

Originally, although Meng Xiujun's face looked a little unsightly, he didn't care too much. After all, everyone gathered together to solve the problem. It's a difficult problem.

Gray's guess was correct.

But what the other party said made him clenched his fists and looked at the scoreboard on the side.

The score at this moment On the board, the Eastern God Alliance and the Star Alliance were tied for first place.

The number of solved problems and the number of unsolved questions were the same.

In this case, the Star Alliance came up with this conjecture, coupled with Gray's words, what did the Star Alliance mean? , anyone who is not a fool can guess it.

No, even a fool knows what Gray wants to do.

Planning to get first place by relying on a conjecture that no one can prove?

Meng Xiujun curled his lips with some disdain.

But even with disdain, At this moment, his expression was a bit unsightly.

Although everyone in the academic competition solves the problem together, everyone also cares about the ranking.

In the past few years, Star Alliance has won the first place in the academic competition every time. This year, the Eastern Academy of Sciences After completing the task, I must win the first place in this year's academic competition.

But now, the Star Alliance has come up with this conjecture. The first place may be a little bit in doubt...
