At Yang Meng's house, I heard Yang Meng's loud voice early in the morning: "I don't care! Today, if you don't give us back the terms that our children should have, I will smash your organizing committee! What? The Ministry of Education? Okay! You can help me convey this: If he dares to be blind, I will go to his house to treat his eyes now! Threaten? That's right, I am a threat! You call the police! Let's see who is particularly unlucky to the end! Lao Tzu hasn't made any movement in the past few years, do you really think that Lao Tzu doesn't exist?"

After he finished speaking, he directly slammed the mobile phone in his hand to the ground and smashed it to pieces.

Di Wei looked helpless next to him: "Master, this is my mobile phone!"

Yang Meng glanced at him: "Let your daughter-in-law buy you another one!"

Di Wei: "。。。。。。。 Forget it. I'll buy one myself. I've been playing with the eagle all my life, but I didn't expect the eagle to peck at it. ”

After hearing this, Yang Meng raised his hand and was about to hit Di Wei: "Who are you talking to?"

Di Wei ran faster than a rabbit, shouting 'Kill someone, kill someone!' and make everyone look sideways.

Long Xixiang frowned and walked in: "I said Mengmeng, what's wrong with you? I heard you scolding the street here early this morning? You are not afraid of letting the children hear it?"

"Scolding the street?" Yang Meng's eyes glared: "Scolding the street is light, I really want to kill people now! You want to kill people too!"

"Take a sip of tea slowly. Miyu Nakamura on the side walked in: "What the hell is going on?"

Yang Meng took the teacup and drank it and asked viciously, "What's the matter?

Miyu Nakamura walked behind Yang Meng and smoothed Yang Meng and said: "Okay, okay, I didn't have such a big temper when I was young, but now I look at a forty-year-old person, why is my temper so big?"

Yang Meng took a deep breath: "When have I lost my temper after all these years? I really can't help it this time! If I tell you two about it, you will be even more angry!"

After hearing this, Long Xixiang smiled and said, "Okay, you, how can we look like you." After educating these bear children over the years, no matter how big the anger is, it has been controlled. ”

"Really?" Yang Meng pointed to the sofa after hearing this: "Come, my dear Principal Long, my dear Vice Principal Zhongcun, you sit down first and I'll tell you what happened." ”

"You can't be as angry as you when anything happens. Long Xixiang sat on the sofa and said, "Say it." ”

Yang Meng explained: "Didn't Mr. Zhou lead the team to participate in the competition?

"How's it going?" asked Ryuxi Xiang and Miyu Nakamura in unison.

Long Xixiang even asked, "How many prizes did Dan Dan win?"

Teacher Zhou, a science teacher at their orphanage school, is now taking DanDan and a few other classmates to participate in the 'National Youth Science and Technology Innovation Competition' in Beidu.

In other words, although Dandan's academic performance is far worse than that of the doll, his small brain is quite good.

Yang Meng bought him a small civilian no-human-machine toy to play with photography, and he had a whim: why are the current civilian drones all quadcopter drones? In this way, the power will be dispersed, the burden on the motor will be increased, the more wings consume, the more power consumed, the shorter the working time, so why not reduce a few propellers?

He asked Yang Meng this question, and Yang Meng actually knew the answer: after all, the more shafts, the more stable.

Civilian non-human-aircraft is not to fly, there must be a gyroscope and a locator, with a locator to know where you are, with a gyroscope to control the drone to do various flight actions, and at the same time there must be a camera to take pictures. In addition, there are accelerometers, sensors, vision sensing systems, infrared ranging devices, and so on. And these devices need to be 'stable' when working, and the four axes are the best stable axes at present, basically, the civilian no-man-machine only has more axes and rarely less, the common is the four axes, followed by the six axes, and the least common is three cubits.

Dandan, on the other hand, doesn't believe in evil, so he has to make a no-human-machine with a lower number of axes, and he is busy with a few friends, and finally he designed a two-axis no-man-machine, which looks like glasses. But it doesn't look good, so it's really good to fly.

But it's not difficult to make these two axes fly, it's hard to keep it stable, especially the camera.

To stop the camera from shaking, you need a stabilizer!

So what kind of stabilizer should you make? A group of children looked up the information together and found that the human eye has a working principle called the anterior hall-eye movement reflex. That is to say, when our head begins to move, our eyes are naturally compensating in the opposite direction, for example, if your head is twisted to the right, the eyes will naturally move to the left: when humans are looking at the mobile phone, no matter how the head turns left and right, the image on the mobile phone is still very stable, which is the anti-shake function that comes with human beings.

But it's unrealistic to make a human-machine camera look like the human eye, at least at the current level of science. Dandan hit the idea on Yang Meng's pets: the two big golden eagles.

This golden eagle has such good eyesight, it can find prey at an altitude of thousands of meters, and it can maintain stability when diving, so what is the reason for this?

he

After consulting the information for a long time, we found that birds also have the same natural anti-shake function as humans, but birds have small heads and big eyes, few eye muscles, and can't turn their eyes around like humans.

Birds can't turn their eyes to keep the picture steady, so they simply make their heads steady!

Because the birds' eyes can't make large movements, in order to maintain the stability of the visual image, they choose to keep the whole head moving and the neck moving, pay attention to the chickens, ducks and geese when they walk, you will find that their necks move back and forth, but the head basically maintains a constant movement. So most birds have an extremely flexible neck so that their vision can adapt to the swing of their body.

Is it possible to make a stabilized camera according to how birds work?

They found Mr. Zhou in the school and talked about his ideas, and in fact, there was a relevant scientific application in this theory. For example, three gyroscopes, stabilizers and the like. And a few of their children tossed around, and they really came up with a simple version of the 'bird neck light source stabilizer'. Compared to other products, this stabilizer has a lower cost and the effect is great!

So Mr. Zhou took them to sign up for the 'National Youth Science and Technology Innovation Competition'.

According to their expectations, this project fully meets the requirements of the competition, right? It is also a 'teenager' and a 'scientific and technological innovation', so it should be no problem to win an award, right? As a result, after Di Wei gave the results to Yang Meng today, Yang Meng directly fried the pot, this is a direct call to scold the organizing committee, Nima, are you looking for death? Dare not give my child an award?

Listening to Yang Meng's words, the two girls were extremely helpless, and Long Xixiang said: "If you don't win the award, you can't win, maybe people have high requirements? Maybe that's why people won't give him a prize!"

Miyu Nakamura also said: "That's it, you are angry like this for such a thing, isn't this unaffordable?"

"It's just, what's the 'we know and we're more angry', where do you see we are angry?"

After hearing this, Yang Meng slapped a piece of paper on the table: "Come on, come on, since you said so, I'll let you see it!"

"What is this?" asked Miu Nakamura.

Yang Meng explained: "I will read a few of the winners of this 'Youth Science and Technology Innovation Competition' to you, and then tell me if you are on fire." ”

After he finished speaking, he didn't wait for the two to answer, and directly picked up the list of winners and read: "Investigation and Research on the Impact of Dianchi Real Estate Project on Kunming Dianchi Lake", "Research on the Function and Mechanism of C10orf67 in the Occurrence and Development of Rectal Cancer", "CAMPUS WIRING-FREE WATER-SAVING REMINDER BASED ON ARDUINO", "RESEARCH ON 6-BA CYTOKININ ON IMPROVING THE SURVIVAL AND GROWTH RATE OF CRAB CLAW ORCHID GRAFTING" 。。。。。。 ”

"Stop, stop, what is this? This is something that middle school students are studying, how can even rectal cancer pop out?"

Miyu Nakamura smiled bitterly, "Why do I suddenly want to resign now and not be the vice principal? I can't even understand the titles of these awards. ”

As a result, Yang Meng waved his hand and said: "I'm sorry, the two principals' wives, I read it wrong just now! I read the list of winners of the primary school group in this National Youth Science and Technology Innovation Competition! Those are all projects at the level of primary school students just now." ”

"WHAT?" Ryūsai Xiang and Miu Nakamura screamed together.

Yang Meng said: "Oh, that West Chamber, why did you just ask, 'Why did even rectal cancer pop out'? Then let me tell you, that project is only the third place in the primary school group!"

Long Xixiang blinked: "Then you tell me what level of the middle school group is?"

Yang Meng took out another list: "Look, we don't have a single award for so many projects in the middle school group, let's not look at the first and second prizes, let's take a look at the list of third prizes。。。。。。。 Tut-tut, I'm embarrassed to read it, for fear that I'll read it wrong!"

Yang Meng coughed twice and cleared his throat: "Look at this, "Isolation and Identification of Duck-derived Chicken Bacillus in Pigeons and Its Pathogenicity to SPF Chicks" 。。。。。。 Come, can you explain to me what this topic means?What are SPF chicks?Commercial house chicks?Look at this, "The discovery of the H9N2 subtype avian influenza virus from pigeons in the live poultry market and the determination of its biological characteristics。。。。。。 A group of middle school students went to a live poultry market to look for the avian influenza virus? This is even more powerful! "Development of the All-Fiber Mach-Zehnder Interferometer。。。。。。 Fortunately, it's not Michael's ear and grandson interferometer, otherwise I would have really fought with him! Look at this again, "Tangshan Adolescent Anti-Social-Personality Disorder (ASPD) Tendency Investigation, Prediction and Intervention Research", this Nima is a paper at the level of the exam, right? Let me tell you, this is the third prize. And I'm not talking about anything that shocks you. ”

"Isn't that what shocked us?" Long Xixiang's eyes widened.

Yang Meng pointed to the table: "Look at this! The children in the first year of high school made a double-plane mass spectrometer! What is this concept? At that time, the Wudaokou Institute of Technology had a team in Beidu and Shenzhen to study this mass spectrometer together, and all kinds of masters and doctors added up to 100 people, and they got up early and studied until the end of 2014, and then came up with the first generation of prototypes. This is a good enough kid in high school, right?

Yang Meng continued to be indignant

"I will read a few second prizes to you, especially now I hate me for reading less, I can't read well!", "Exploration of the therapeutic effect and mechanism of golden crude polysaccharides in chicken on oral ulcers", "Influence of flavonoids (ZGM1) on the aggregation of β amyloid small peptides and extreme exploration", "Discussion on the inhibition of M1 macrophage polarization and its function by CH13L1", "Exploration of the effect and mechanism of microgravity on the osteogenic differentiation of stem cells"!

Long Xixiang and Nakamura Miyu were dumbfounded: "This is the second prize, what is the first prize?"

"What's the first prize?" Yang Meng slapped the table: "That's a good question! I'll read a few to you!" "An Artificially Coded DNA Anti-counterfeiting Ink", "Selective Release of Anticancer Drugs Based on Responsive Nanoparticles", "The Role of 3D Printing Multisensory Prompting System in Improving Parkinson's Disease Patients' Inability and Multimodal Brain Mechanism", "Research on Genetic Diversity and Conservation Countermeasures of Small Stone Accumulation in Round Leaves", "Preparation and Application of Force-Induced Polychromatic Transition Materials Based on Spiropyran-Pyrene Bichrochromite", " Study on ECL Ratio Detection of Heterosexual Inscription Marker Calcitonin for Medullary Thyroid Carcinoma", "Blockchain Optimization Model Based on Consistent Hashing Algorithm", "Research and Preparation of Flexible Memristor and Cross Array as a Component from Egg White", 。。。。。。。 Do you still want me to read it?"

Long Xixiang was silent for a long time, and finally two words popped out of his mouth: "Fuck! I feel like my book has been read in vain! This is a middle school student?

Yang Meng said with a smile: "Let you see the most ruthless! The first prize winner, a paper by Zeng Zeng, is called "Research on the Heat Treatment Process of Improving the Hardness of Magnesium Alloy Based on Synchrotron Radiation Technology", where was this experiment done? Neither Ph.D. or master's students can apply independently, so can anyone tell me how this middle school student applied and who asked this middle school student to use the equipment?"

Yang Meng knocked on the paper on the table and continued: "And the student Duan who just said "Making a Component with Egg Whites - Research and Preparation of Flexible Memristor and Cross Array", it sounds like a manual labor class, but I checked the State Intellectual Property Office, and there happens to be a patent in it, na, it is the patent with the application publication number 109860389A, what is the name?" A photoelectric dual-control flexible egg white memristor', the patent inventor and the instructor of this classmate have the same name and surname in the same city, and the second inventor also has the surname Duan! What does this mean? Take your family's patents to participate in the competition? This is especially small to say that this is to train children to cheat and lie, and to say that it is academic misconduct and educational fairness, this is a crime! These people are really just brains? A primary school student goes to study genetics in just a few days, from beginner to master? I will read to you a self-exposition of a primary school student who studies cancer, saying: 'Understand the principle of PCR technology, know the design of PCR primers, the concept of PA substrate and fluorescent genes, and roughly understand why the mRNA expression level of which genes can be known through the comparison of fluorescence intensity, and then judge the expression level and function of a gene in cells'! That's PCR technology! Polymerase chain reaction! Using the principle of double-stranded replication of DNA, a piece of DNA is taken out and replicated in vitro! This is still pediatrics, and a series of scientific studies have been carried out, such as C10orf67 knockdown expression, inhibition of cell reproduction, and so on! This Nima was researched by himself, and I will kick your head as a ball!"

Speaking of this, Yang Meng took a deep breath and stretched out four fingers: "People have come up with such a great result in four days, and it must be him who gives him the Nobel Prize for four years! The result is like this? It's only the third place in the primary school group! Isn't it strange that they didn't win the award in our family?"

Long Xixiang slapped the table: "Grass is special, it's not such a bully! Doesn't this competition say that it advocates the all-round development and quality education of young people? How did it become a large-scale battle site? These papers all need experiments, but where did they get the test equipment? Just like you said about synchrotron radiation technology experiments, what kind of trust can make the Magic Capital synchrotron radiation light source agree to lend the laboratory and equipment to these primary and secondary school students? And how can such experiments be completed in a short period of time?"

"Money and relationships!" Yang Meng pointed to the list on the table: "You take a look at this list of awards, which of those schools is not a so-called famous school?

Miyu Nakamura on the side asked puzzledly, "What are they doing this for?"

Yang Meng snorted coldly: "At the earliest, if you win the first and second prizes in the National Youth Science and Technology Innovation Competition in high school, you can be sent to university! Later, the guarantee policy was canceled, but if you win the first and second prizes, you can add 20 points to the college entrance examination!

"I'm going to call them right now and scold them to death! I really think my mother is a bully? What are you doing with such a game? I'm going to do it!"

“。。。。。。 Why is your temper worse than mine?"
