When Lu Ming talked to Liuxiang about something like this before, what he got back was basically a burst of refutation.

Liuxiang dared to refute Lu Ming, it was because she relied on her, she knew that she could make a small report after she was speechless, so she had no fear.

But when facing Li Hanying, Liuxiang didn't seem to be able to find this kind of panacea.

After a burst of red faces, Liuxiang finally replied, "Yes...... yes......"

"That's why I said it!" Li Hanyingmeng, who didn't know what was going on, said, "How useful can a quantum computer be compared to going to the hospital to take an MRI?" If it is true that some of the engineering calculations in this country are far beyond the scope of traditional computer capabilities, then there is indeed a need for investment, but some small countries ...... Didn't I say that there is no point in making quantum computers because they don't even have the ability to launch satellites on their own, and the scale of industry is far from the point where nuclear power is needed to supply energy?

People still have to recognize themselves after all, what is the use of not having the ability to be in place and pursuing so many vain things?

I really know this very well, and there are some scholars in China...... Brainless, I really don't know what they think, some technology, you told me that it is related to the country, and I have been using things from outsiders for fear that one day people will not provide it, which is a bit reasonable, but some, for example, ...... Is there any difference between domestic and foreign countries such as the spring blade that automatically trips the electric kettle, the glass glue that sticks to the fish tank, and the car gearbox? Is it really necessary to spend that much time researching?

Isn't it more realistic to put that effort on improving the ball bearing process?

And the funds are easier to come down, and in the end, the bonuses can be more. ”

Speaking of this, Li Hanying actually complained again, "It's been good in the past few years, at least our teacher's case of light field communication has been established, in the past few years, the unit was so stingy that it didn't even have a dormitory, and it paid more than 3,000 yuan a month, and then many colleagues around me always chewed my tongue behind my back and said about my father, so that I was embarrassed to call my father to ask for money, and then the teacher didn't allow us to go out to advertise those companies, saying that we were afraid that we would accidentally help the scammers stand on the platform. Sometimes I am so poor that I can't even pay the rent, so I can only work as a tailor at home and make some handicrafts to earn some pocket money, and I can only stare at beautiful clothes and bags, and I can only swallow saliva when I touch delicious things, and I feel so pitiful when I think about it......"

Speaking of this, Li Hanying looked at Li Lingfeng very sadly, "I just ran into such an ignorant dead brother again, my father didn't allow him to play games, he was good, when he came home during the winter and summer vacations, he always picked me up and asked me to buy it for him!" Thousands of dollars at once, where can I get it? ”

Li Lingfeng turned yellow, pointed at his elder sister and argued, "You, you, don't smear people's innocence out of thin air, when have I ever done such a childish thing?" ”

"What have I slandered you? Aren't you naïve? Let me tell you that Sister Xiao ......" Li Hanying turned to Liuxiang again, "Don't look at him now pretending to be mature and stable, in fact, he is so naïve that he is dying!" At the beginning, because I took him to the street once and didn't buy him marshmallows, this guy actually turned out the album I hid in the dictionary and took it to my dad to make a small report!!

Sister Xiao, do you know how hard I put into hiding that album in the first place? Take a utility knife and dig page by page against the vernier caliper! The album box is also engraved with a hidden buckle, which is tightly embedded, and it is locked directly after closing the dictionary, and it is impossible to shake it off no matter how you shake it! I spent two days and two nights calculating the friction coefficient and torque of the paper!! ”

What do you say...... Lu Ming and Hongchen on the side were embarrassed.

Are you embarrassed to say that others are naïve?

The two of them were embarrassed, and Li Lingfeng was also embarrassed, "Are you embarrassed to talk about me?" At that time, they were all in their twenties who could be aunts, and they were still chasing stars? Forget about chasing stars, but still chase that kind of brain-dead star? ”

Li Hanying was instantly furious, stomped his feet, flew up with an arrow step, raised his hand and rewarded his younger brother with a neat hand knife, and then reprimanded Li Lingfeng, who was a head taller than himself, with his waist in a low position, "I don't allow you to slander XXX brother!" Do you know how hard people work? People can release albums when they are in their teens, what were you doing when you were in your teens? I'm in junior high school.,And bullied by girls.,When I was in elementary school, I fought with my classmates for three days and two for a little trivial thing.,Fight it.、You haven't won a single time.,If you can't win, don't fight.、Don't cry if a big man has the ability! It's not that I don't know that your teacher is your old sister's former classmate, it's embarrassing, you know! ”

Li Hanying was embarrassed at that time, and others didn't know, but they could see from Li Lingfeng's face that he must feel quite embarrassed now.

"No, I said you're really ...... Ah! Li Lingfeng was so anxious that he directly stretched out his hand to cover his eyes, "The three big characters of scientist can be printed on the business card, and he also said that he is a XXX fan, and he is not ashamed." ”

"What's wrong with me chasing stars?" Li Hanying responded with a proud face, "Can't scientists chase stars?" Dad, he's an old stubborn, and you're a little stubborn! I don't care what those guys on the Internet slander, XXX is my idol anyway! If anyone can grab me a ticket to my XXX brother's concert, I will definitely be happy to heaven! ”

Li Lingfeng grinned and mocked, "So, my brother-in-law chased you with a concert ticket for 30 yuan a piece?" ”

Li Hanying also blushed a little, but she immediately responded, "Your brother-in-law is not like you!" So narrow-minded, so crowded! He will never denigrate my preferences, nor will he force me to accept his preferences, and every day when I go home and see him turn on the computer and look at the inexplicable baseball game video, I am so impressed! Do you think when he looks at me chasing stars, is it the same as when I look at him chasing stars? How could he be so calm?

Boundary! This is called the realm, what do you know about a little kid who sold his sister for a marshmallow? ”

"Yes, I don't have a realm, you guys who almost screwed off his brother's ears for a 20 yuan album are high?"

"You still have the face to say, I can't wait to kill you!" Li Hanying was so angry that the sound of "squeaking" teeth fighting came out of his mouth, "It's not that you don't know what kind of temper Dad has, this is not allowed, this is not allowed, if you sue me like this, where will he give me pocket money?" ”

The sister and brother went back and forth, looking very funny, but the others looked at each other.

Li Lingfeng was also quite helpless, and he didn't dare to go to see Liuxiang, but directly apologized to Lu Ming and Hongchen, "I'm sorry, I made you laugh, my father was very strict, but I didn't expect it to be counterproductive and teach such a miser." ”

Li Hanying heard such a description, but she was lifeless, "What's wrong with my miser?" Are you not convinced?

What's so bad about being a miser?

In my opinion, these three words are praise, okay?

In life, one strives for fame and the other pursues profit, and our teacher said that in our business, we would rather be a miser than a gentleman.

Chasing fame is a very dangerous thing, you see that there are two academic fraud scandals on the Internet in three days, which of those people is not going for fame? Fake theories can't be industrialized, where can you make money?

It's just academic fraud, some scientists who want to be famous and crazy can't do anything on the right path, and they go straight away to study those gods and ghosts, and the XXX who punches Newton and kicks Maxwell uploaded on the Internet has studied the use of resonance to induce earthquakes, which almost destroyed the entire human civilization!

Such a person is the most terrifying, you don't know whether he can save people or kill people after he researches something, because even he himself doesn't know the answer.

Research for the sake of research is not necessarily a bad thing, but being famous for the sake of being famous is definitely not a good thing! ”

After a while, Li Lingfeng was speechless, "You said you are really ...... It's been pestered to a certain point. ”

Li Hanying responded arrogantly, "Hehe, you can't say it, right?" Dare to contradict your sister and me? Looking for death? ”

Liu Lingfeng shook his head, didn't care about her anymore, and instead began to say to Lu Ming and Hongchen, "My sister, she's like this, everyone doesn't have to care about her......"

"Hey, where is it...... Lu Ming hurriedly waved his hand, "Miss Li is such a knowledgeable and Confucian person, she is willing to deign to guide us in our work, we can't ask for this." ”

Li Hanying was quite happy to hear this, "My stupid brother can meet such a good leader as you, that's really a great blessing, if he usually does something wrong, even if you educate, boys, if you don't fight, you can't succeed, when I was a child, my father never treated me as a girl, and scolded me so fiercely, didn't he come over the same?" Anyway, he's so thick-skinned, it's okay ......" After speaking, she turned to Li Lingfeng again, "I heard it, what about you, the leader of the family handed over such an important matter to you, that is the trust in you, you can't fish for three days and dry the net for two days and the days of gangsters will pass, no matter how small the matter, you must do your best to repay the organization's cultivation of you, understand?" ”

Li Lingfeng wanted to cry without tears, and he didn't break the surface, just stood aside silently.

Li Hanying saw that he didn't speak, and he also hated that iron could not become steel, so he hurriedly shook his foot over, "Oh, the leaders of the people came to inspect the work, you should hurry up and report the work, really, so stupid, I really don't know what to do in the future?" ”

After talking about her younger brother, she smirked at Lu Ming and Hongchen again, "I'm sorry, my younger brother is actually a good boy, but he is too wooden, I don't know how to express myself, don't forget to go to your heart...... Well, maybe I'm embarrassed to be my sister on the side, let's talk first, let's talk first, I'll go over there and see ...... first."

After speaking, she floated away, Lu Ming wanted to stay, but he didn't expect this Li Hanying...... Obviously a scientist, the physical fitness is quite good, a sliding step instantly floated out two or three meters, I don't know if it's because I have learned human cloud dynamics, know how to exert force, or because the learning ability is too strong, and the game operation is also a little bit clear.

Anyway, I didn't keep it.

But fortunately, after Li Hanying left, Li Lingfeng was indeed much more comfortable than just now, and he didn't say anything false, and directly began to "report" to work.

Mainly to say "conception", according to his plan, when the time comes, 4 huge chessboards will be drawn out according to the circular arrangement on this field, and then find those cute girls to wear custom fashion cosplay "flags", simply put, it is the kind of "chess warrior" on TV, but there are differences......

Because this field is a plain, Go is not as good as chess, the 17*17 field is too big, and the board is placed on the flat ground, and the audience behind cannot see it.

The cost of stacking the back seats is too great, and because it is not easy to estimate how many people will come to see it at that time, it will be embarrassing if there are only a few people who come and there is no head in the high seats.

When the time comes, when people see that there are few people to watch, under the influence of herd psychology, those who were originally interested may have run away.

Therefore, the solution conceived by Li Lingfeng is to set up several mirror groups next to the chessboard through the method of optical reflection, and turn the horizontal into an inclined plane.

In fact, it's very simple to say, the periscope principle, and the detective uses a rotten stalk.

But it's a bit difficult to actually operate, and the reason is just as simple, the chessboard is too big, there are not so big mirrors, and they have to be spliced.

If you splice it, the imprint is obvious, and it's easy to say that it matches the lines of the board itself, but if you look at it from the side, the line pattern of the board and the mirror will be fragmented and the look is very poor.

In order to solve this problem, Li Lingfeng invited his elder sister.

It's very mysterious and obscure, after all, he doesn't study physics, and he can't explain many things himself.

He couldn't make sense, but Lu Ming understood......

Because this is also a detective's rotten meme - polarized light.

To put it simply, it's like a fence, and light is an electromagnetic wave, a transverse wave.

In high school physics class, no one who has slept knows that transverse waves do not represent "transverse propagation" waves, but that the propagation direction of the wave is perpendicular to the propagation direction of the particle, and vice versa.

Water waves, including the waves with marbles when Li Hanying just explained gravitational waves, are all transverse waves.

In the case of longitudinal waves, it is more common to see springs, or a little more disgusting, the way a caterpillar crawls forward.

Light is a transverse wave, so there is a polarization phenomenon.

To put it simply, it is a fence, imagine that a light comes over, in fact, it is not "one", but a 360-degree all-round countless electromagnetic waves without dead angles, and these countless electromagnetic waves have different directions;

On its path, put a fence and the gap is vertical, then only the wave in the vertical direction can pass, and the others will be stopped;

What if you put a horizontal fence a little bit ahead?

Only the vertical wave goes this way, but this wave can't pass, because this fence is horizontal, and only the horizontal passes.

The person on the other side can't see anything.

This is called polarized light, and the fence is called a polarizer. ”
