Halfway through, Cheng Biting Jin, everyone's attention was focused on Director Guo.

A young female "master" didn't seem to be angry, and stepped forward and asked, "Sir, do you think the special function just now is fake?" ”

"It can't be faker."

Director Guo used the sharp eyes he had cultivated since his anti-counterfeiting to debunk the tricks that the magician had just become, one after another, and even performed them on stage.

The atmosphere reached a climax all of a sudden, and the committee members booed, and Chairman Wang and Chairman Ge of the Jiangnan Provincial Committee of the Chinese People's Political Consultative Conference (CPPCC) looked at Li Xiaoshan with a smile, as if they wanted to know how he would end up next.

To everyone's surprise, the female "master" not only did not slip away, but clapped her hands and said with a smile: "This gentleman has vision, but the performance just now just wants everyone to know the Tao, and the idea of reading words, shaking pills, white water and one-finger Zen blackout fans are all deceptive, not real special functions." Even if this gentleman doesn't debunk it, we will make those tricks public. ”

"Little girl, stop quibbling. Isn't it just a show, whether it's true or not, we won't care about you. ”

Chairman Wang obviously didn't want to embarrass them too much, but the female "master" didn't seem to appreciate it, and even pointed behind him, and said with a smile: "Sir, I didn't quibble, but I really had this plan, I don't believe you look at the table behind you." ”

With the direction of her fingers, everyone found that there was a thick stack of materials on the table, and they picked it up and looked at it, and it was indeed the trick of the "special function" just now.

Director Guo has a little popularity. was recognized by a sharp-eyed committee member: "Director Guo." You've come at a better time. Fortunately, people have been prepared, otherwise a good show will be disturbed by you again. ”

Director Guo was happy and said meaningfully: "Professor Lin, don't tell me that I didn't see anything just now. ”

"I don't have your fiery eyes, I really didn't see it."

It was important to get down to business, but Director Guo was not interested in arguing with him, so he turned around and asked, "Little girl, since you said that these are not real special functions. Then please perform a real one, so that we can open our eyes. ”

"No problem, I hope you won't be disappointed."

As soon as Zhang Lan's words fell, Li Weifeng walked up to everyone and said in a frustrated voice: "The levitation technique is one of the top ten superpowers of human beings. Countless scientists have not been able to decipher the floating phenomenon to this day. I don't have the skills to defy gravity and float my body slowly like those powers. But I can use my mind to levitate this lighter in the air. ”

He didn't say anything, he first recited a few incantations in a lively manner, and then slowly released his right hand. A lighter was actually hanging in the air of the "Dharma platform".

One of the commissioners ran up and circled the lighter with his arm. Exclaimed: "Really! There is really no wire! ”

Chairman Wang didn't believe it, glanced at Chairman Ge, and also walked up to the stage and touched it up and down, left and right, and sure enough, there was no rope or line, and it was suspended in the air like a fake. At this moment, several "masters" were pointing at the lighter in mid-air with their eyes closed and painful expressions, as if they were trying to make sure it didn't fall.

"Sir, this lighter is given to you as a souvenir."

Zhang Lan grabbed the lighter and stuffed it into Chairman Wang's hand, picked up a spoon casually, closed her eyes and made a gesture, so that the spoon was also suspended in the position just now.

"God, God!"

"This can't be fake, it's a special function."

In the midst of a burst of whispering discussions, several committee members even brought cameras and "clicked" this special function on the film.

"Regarding the human body floating in the air, Professor Kalemans of the United Kingdom and several scientists in India have found that it has long been recorded in the ancient Indian book "Buddhist Sutra": as early as 2,000 years ago, Buddhist monks could easily fly into the sky, and they painted the scenery they saw in the air into huge paintings."

Li Weifeng opened his eyes and continued: "Indian archaeologists have found a huge stone sculpture, which depicts the scenery of the Mandar Plain in the Ganges River valley in India 2,000 years ago, and it is completely drawn from a bird's-eye view. Knowing that there were no helicopters at that time, how could people draw it from above? So it's not a myth, it's that the human body can float into the air.

As I said earlier, we don't have enough power to take to the skies like those 'powers'. But in order to really realize that creatures can do this, we're going to go ahead and keep a live frog suspended in the air. ”

There is a "master" who is invited to watch the Spring Festival Gala every year, and it is said that it is because CCTV is worried that if he is not invited, then he will destroy the light bulbs on the stage.

This kind of thing would rather be believed than not believed, not to mention that people have performed a "special function" that is too real to be true.

One of the committee members couldn't help but ask: "Master, it's so cold outside, how can there be frogs now?" ”

Li Weifeng took out a frog from the incubator and explained with a smile: "Artificially bred one, I just brought a few, to be exact, bullfrogs, and when the performance is over, you can send it to the kitchen, please ask the chef to braise it, the taste is very good, I believe everyone will praise it after tasting it." ”

Not only is he very knowledgeable, but he also knows a lot about the history of India, and he is quite humorous. The whole "academic master", unlike those who didn't even graduate from elementary school, is mysterious.

The protégé was funny, Director Guo smiled and said nothing, and Professor Lin, who knew him, held his chin to study the "Dharma Table", looked at the cover embroidered with various patterns on it, and then looked at the platform below.

However, this time, the "master" did not let the frog be suspended in the air like a lighter, but suspended in a container like an oil drum.

When everyone confirmed that this was not a trick, but a real special function, the four "masters" of one woman, three men and four "masters" then "finished their work" and rested.

"Director Guo, do you see anything?"

Director Guo asked rhetorically, "What about you?" ”

Professor Lin glanced at the delicate "Dharma Table" and said meaningfully: "It's a little interesting." But I don't understand the bucket of the suspended frog. ”

Director Guo leaned into his ear and whispered, "Then why don't you break it down?" ”

Professor Lin smiled. Holding an arm in one hand. Covering his mouth with one hand, he said quietly: "You think I can't see that you are in a group?" ”

"What about you, who are you with?"

"I'm old and young, don't beat me."

Those so-called "masters" have become more and more rampant, intimidation of anti-science people is commonplace, and even several anti-pseudoscience experts and professors have been cut down by those they instigate, and the whole triad and cult are combined.

Director Guo nodded noncommittally. There was no further sound. Professor Lin sighed secretly and asked in a low voice, "Lao Guo, where did these children come from?" ”

"NB Labs."

Thinking of Li Xiaoshan's strange behavior during dinner, Professor Lin suddenly realized: "I should have thought of it a long time ago, okay, great, they have no scruples, they can toss hard, unlike us, they are afraid to do everything." ”

He is a dignified academician of the Chinese Academy of Sciences. Enjoying the special allowance of the State Council, he actually pretended to be deaf and dumb on such a serious scientific issue. Director Guo snorted coldly, and said sarcastically: "Remove that 'we', don't take me with you." ”

After so many years, Professor Lin was still that virtuous, Professor Lin did not get angry, but asked with interest: "Okay, I am cowardly and afraid, you are jealous and hateful." But Lao Guo, what is the next show? ”

"I don't know what to do."

"I really don't know what to do?"

"What are you lying to, it's the age of young people, and I'm just going to do it."

The "masters" rested for about ten minutes, and one of their "disciples" moved to the side of the round glass inlaid with various patterns. Immediately after, a refrigerator-like cabinet was pushed out by several other disciples.

"That's right, it's a refrigerator."

Li Weifeng lifted the curtain and walked to the committee members with full energy, pointed to the cabinet and introduced: "The difference is that it has more power and better refrigeration effect than a normal household refrigerator. ”

What an interesting young man, Chairman Wang couldn't help but smile and asked, "Master, how good is the refrigeration effect of this refrigerator?" ”

"It can reach minus a few hundred degrees."

In front of everyone's eyes, he opened the refrigerator and took out a bottle that was bubbling cold, and said with a wicked smile: "Leaders, if you want to feel what it's like to feel minus 200 degrees, then touch it like me." ”

"Don't!"

Director Han is a doctor, and he knows how much harm minus 200 degrees will cause to the skin, so he hurriedly reminded: "Dozens of degrees below zero can freeze people's ears, which is very dangerous, so don't try it." ”

Seeing that Chairman Wang looked at him, Professor Lin nodded heavily and confirmed: "Director Han is right, the temperature is too low to touch. ”

"But he ......"

"Does it mean that I'm holding on to it?" Li Weifeng held up the bottle of white smoke and said with a smug smile: "That's because I'm a master, and I have special functions, so I can not only touch it, but even drink it." ”

It seemed that everyone had doubts about the temperature of the bottle, and he put the bottle on a glass lid on the buffet box, and after a while, the thick glass lid "snapped" and froze in front of everyone.

"The glass itself will not freeze and crack, only when the temperature difference between the inside and outside is relatively large, will it freeze and crack like now."

He explained, took out a bottle from the refrigerator that was also steaming white, unscrewed the lid in front of everyone, poured the liquid inside into his mouth, and then opened his mouth again and spit it out, but most of the spitting out was white. The temperature is indeed very low, and you can feel a chill when you are away from so many, and his performance makes everyone tremble.

A committee member suddenly shouted: "No, it's more than 200 degrees below zero, and the water should have frozen a long time ago." ”

Zhang Lan smiled and explained, "Sir, you are right, but the bottle is not water, but liquid nitrogen. As for whether it's minus 200 degrees, I have a special thermometer here, so you can wear gloves and measure it yourself. ”

Several university professors agreed that the thermometer was fine, and the temperature of the bottle and the liquid nitrogen in the bottle was as low as they said. Such a cold thing can not only be grasped in the hand, but even dare to drink it, the committee members are completely convinced, and even the last suspicion has been thrown out of the clouds.

Just when everyone was talking, the "master" who drank nitrogen actually laughed and said: "The temperature is indeed very low. Such low temperatures can be harmful. But I grabbed it and drank it. It is not a specific function, because when the skin is in contact with nitrogen fixation for a short time, it is not directly exposed to nitrogen fixation, because the vaporization is faster, a thin layer of gas is formed between the skin and nitrogen fixation, and the heat transfer of the gas is slow, so the short-term contact will not cause harm. However, drinking liquid nitrogen is still very dangerous, and I will not hurt if I do it. It doesn't mean you can do it, don't imitate it. ”

Debunk yourself, what the hell are you doing?

Chairman Wang was confused by tonight's one play after another, and couldn't help asking, "Master, so the lighter, the spoon and the frog hanging in the air just now are all fake?" ”

"Of course it's true, but it's not a special feature, it's science."

Li Weifeng took a small box from Zhang Lan's hand, and while taking out a small thing like a part from it, he wrapped it neatly with paper. And poured liquid nitrogen on it, while patiently explaining: "The reason why the lighter and spoon can be suspended in the air. We made a prop according to the principle of magnetic levitation, but it was relatively large, and everyone didn't notice it. ”

"That 'Fatai'?"

"Well, it's a large coil of high-frequency current, and the eddy current generated by the high-frequency electromagnetic field generated by it on the surface of the metal is used to levitate the lighter and spoon. It is worth mentioning that this technology has been applied, such as maglev elevators, maglev bearings, maglev electric sprinklers and even maglev trains, etc. ”

It turned out to be doing popular science, and Chairman Ge of the Jiangnan Provincial Political Consultative Conference was happy, and asked with a smile: "Young man, where is the frog?" ”

"Different objects exhibit different properties in a magnetic field. But it can be roughly divided into three categories, one is called paramagnetic, one is called diamagnetic, and one is called ferromagnetic. For example, iron and nickel are ferromagnetic, rare earth elements are paramagnetic, and frogs are diamagnetic, and diamagnetic objects in a magnetic field are diamagnetic.

So when a frog is put into a magnetic field, each of its atoms is like a small magnetic needle, and the external magnetic field acts on these small magnetic needles to produce a force on the frog, and if the strength of the magnetic field is appropriate, this force is balanced with the gravitational force of the frog, then it can hang in the air. ”

Li Weifeng walked to the round glass they had prepared, put the small round piece in his hand on it, and let it float above the edge of the glass, and then gently pushed, the small round piece actually rotated around the round glass hanging in the air, looked at the way everyone looked at each other, and then said: "What you see now is the principle of electromagnetic levitation that makes the train fly up, which is completely different from the principle of frog levitation. ”

A unique popular science, if they don't say it themselves, who will believe that this is not a special function?

No matter how stupid Chairman Wang was, he couldn't guess what was going on, so he turned around and asked with a smile: "Mr. Li, these people should be from the NB laboratory, right?" ”

"Yes."

Li Xiaoshan walked among the crowd and proudly introduced: "Chairman Wang, Chairman Ge, members, please allow me to formally introduce that these four are all doctoral students of the NB Laboratory, Li Weifeng and Zhang Lan, from the Department of Basic Research of the NB Laboratory; Qian Xiaojin, Faculty of Systems Engineering; Tang Quan, from the Faculty of Applied Technology. ”

Director Han of the Second Provincial People's Court reacted and couldn't help laughing and scolding: "Okay, you Mr. Li, you are pretending to be a ghost and watching our jokes." ”

"Director Han, I don't think it's a joke."

Li Xiaoshan's face was straight, and while looking around at everyone, he said solemnly: "As early as 1934, Mr. Lu Xun wrote in an essay: When I was a child, I watched my classmates make small tricks, 'listening to words in my ears', 'paper people bleed', I thought it was very interesting. At the temple fair, there were people who taught these tricks, a few copper dollars, and when they learned it, it was boring from then on.

But it is such a simple 'little trick' that many people, including some scientists, believe it. If these peculiar functions and mysterious phenomena are allowed to continue, the values of truth and science will be destroyed, and the people of the whole country will fall into the abyss of confusion and superstition.

As a member of the National Committee of the Chinese People's Political Consultative Conference (CPPCC), I cannot turn a blind eye to those charlatans and swindlers, and I cannot remain indifferent to what information tea they sell, what functional medicines they sell, and what report meetings they hold when they openly sell tickets. ”

Chairman Wang reacted and asked in a low voice, "Mr. Li, is this your proposal this year?" ”

"Yes, my proposal is 'Defend the dignity of science and law, oppose pseudoscience, and break feudal superstitions'! I firmly believe that science will eventually triumph over pseudoscience and truth will eventually triumph over falsehood, but this is a very important and urgent task that must rely on the strength of the scientific community, the legal community, and the whole society, and it needs to be persisted in for a long time. ”

Director Guo walked up to him and said excitedly: "A good one to defend the dignity of science and law, oppose pseudoscience, and break feudal superstitions." Mr. Li, this proposal counts me, and we are jointly named. ”

"And me."

"I'm one too."

As Professor Lin raised his hand to express his position, dozens of members of the Dongguang delegation and the Jiangnan delegation expressed their support one after another.

Four Ph.D. students from the NB Lab, including Li Weifeng and Zhang Lan, as well as the NB electrical engineers who assisted them in their performance, once again became the center of attention, and they gathered around the round glass demonstrating the principle of the maglev train and asked questions and asked this and that.

The four of them answered all questions and introduced the principle in simple terms.

"This is a thin sapphire wafer coated with a thin ceramic layer of yttrium-barium copper oxide, which becomes a superconducting material at extremely cold temperatures, and superconductivity is the conduction of electricity without energy loss...... When it is placed on a magnet, the superconducting material and the magnet repel each other, which is known in physics as the 'Meissner effect'. ”

…………

"What an eye-opener, what an eye-opener!" Chairman Wang of the Provincial Committee of the Chinese People's Political Consultative Conference sighed: "Mr. Li, I have long heard that your laboratory has a high academic level, and today is an eye-opener. (To be continued......)
