Zhang Zheng said: "I didn't want to leak the secret of heaven, but for everyone's curiosity, I'll tell you, this matter is indeed done by me." ”。

"Ahh I said, Brother Zhang, did you really do it? I wondered, how did you do that? Do you really have the special ability of 'teleportation'? Charlene asked curiously.

"Haha, I said Sister Xia, how can you, a talented student who graduated from Peking University, believe in these messy things?" Zhang Zheng said with a smile.

"There are a lot of special performances, I saw it with my own eyes, you say, can I not believe it?" Charlene said.

"In fact, what you see with your own eyes may not be true, there are many seemingly incredible phenomena, in fact, the use of magic techniques or technological means can also be realized. For example......"

When Zhang Zheng said 'for example', a cup of milk in front of Xia Lin suddenly moved slowly.

"Wow! Come and see, how did my milk cup move on its own? It's not an earthquake, is it? Seeing the mysterious phenomenon happening in front of her, Charlene couldn't help but shout loudly.

"Wow! Is it really a special function? "Everyone was stunned by this strange phenomenon.

"Stop!" Zhang Zheng shouted, and the cup stopped obediently.

"Ahh It turned out that Brother Zhang was playing tricks! Cui Yingying and others are humane.

"Actually, I'm just using this way to tell everyone that there are no special functions in the world at all, and there are no superpowers, let alone masters." Zhang Zheng said.

"And how did you do it?" Charlene asked puzzled.

"I just used my internal strength to make a small displacement of the object, and it has nothing to do with any special functions and superpowers."

"The problem is that at the beginning of this year, Sichuan produced a child who could read and write by ear, and even the secretary of the provincial party committee, the director of the State Commission of Science and Technology and the Commission of Science and Technology and top scientists came forward to support it. What's even more interesting is that there is a young man named Zhang Baosheng, who claims that he not only has the function of "non-eye vision", but also has the special function of using the idea of 'sending things and picking up goods'. Charlene asked.

"My opinion is very simple, there are no special functions and superpowers in the world at all, so whether it is ear literacy or mind transfer, it is all fake."

"Why? There's always a reason, right? ”

"Of course there is a reason, because these things are contrary to basic scientific common sense. For example, if you understand the structure and function of the eye, you will find that the special function of the so-called 'ear literacy' is pure nonsense. ”

"The issue of ear literacy is now very controversial, and I heard that even the top level of the central government has been alarmed. Brother Zhang, you are a doctor, you should know the most about human science, can you explain this problem to us? Although Charlene is about to enter her first year, this curious attitude is not much worse than that of a little girl.

"Okay, take this opportunity, I'll give you a science about the knowledge of eyes and ears, as for the question of whether the ears can be literate, after you listen, judge for yourself......"

"Brother Zhang, stop talking nonsense, don't you see everyone's ears up?" Liang Li said.

"Haha! The ears are up, that's a rabbit ......," Zhang Zheng laughed.

"You're the rabbit. Hurry up, don't grind. Liang Li urged. "Well, I'm not going to talk nonsense. The human eye is composed of multiple parts, and the outermost part of the eyeball is a colorless and transparent cornea, like the lens of a camera. There is a small round hole in the center of the eyeball called the pupil, through which the light from the outside enters the inside of the eyeball, and after the refraction of the lens and vitreous, it forms an inverted image on the retina. The retina is equivalent to the film in the camera, which is a component of photosensitive imaging, on which there are countless photoreceptor cells, when they receive the image stimulation signal, they will convert the object image information into nerve impulses, and through the transmission of the optic nerve, it will be transmitted to the visual center of the cerebral cortex to form vision. In this way, human beings can truly feel the images and colors of thousands of things. ”

"Brother Zhang, why are your eyes so complicated?" Zhang Qian asked.

"Although what I introduced seems to be very simple, it is difficult to imagine the actual complexity of the glasses, so to speak, as complex as it is."

"Brother Zhang, in other words, only organs with this visual function can see the shape and color of objects?" Zhang Qian asked.

"You're right, it's true."

"I don't agree with you, I think that through the touch of the body, it is also possible to perceive or distinguish the shape of different objects, except for color, of course." Zhang Qian raised a different opinion.

"Oh, could you please give me an example?"

"I'll give you the example of a blind man. Blind people, although they can't see the world with their eyes, can use their limbs to perceive the world. For example, they can use their hands to distinguish objects such as chopsticks and spoons. You can also use your feet to distinguish blind alleys, etc., ......"

"Haha! I'm a girl, you're such a little fool, judging from the example you gave, doesn't our IQ seem to be much higher than Nana's? Zhang Zheng said with a smile.
