Cyber Ghosts

What a little bald man who forgot his friends! Ho Ning despised Liu Shuai in his heart, and continued, "Yes, after discovering this phenomenon, many physicists did not believe in this matter, because it was logically unreasonable, and it also encountered us in reality. The experience I got was completely different. So Schrodinger, a man, cited a famous thought experiment, Schrodinger's cat. "

Speaking of this, the eyes in the four eyes are all looking at Haoning. Even Longfei, a PhD in nuclear physics, looks at him. Haoning feels a little embarrassed and pauses. Is it right? "

"This is basically what it means," Ren Lao nodded with a smile. "Some small details, such as this so-called observer is not specifically an intuitively understood observer, but after all, it is too cumbersome to understand the details without elaborating."

Hao Ning was happy: Actually, I only knew so much. You asked me to explain that I could n’t explain it. I saw that I was able to fool it, so I continued: "This Schrodinger said, if there is such a black box, the box There is a cat, and a bottle of poison, and then there is a radioactive element. As long as he decays, this bottle of poison will poison the cat through the organ. If it does not decay, the cat is alive. "

"What is decay?" Xiaowen asked this time.

"Uh ..." Honing is not good at joking with Xiaowen, and he scratched his head and thought for a while, "You can simply understand it as a special change. This change has a characteristic, you will know that it will change in a period of time. -For example, it may change within a week, but no one knows when it will change during the week. "

"I will come in a week, but no one knows exactly when this week will come ..." Xiao Wen frowned, and said subconsciously, "Listening to how like aunt ..."

"Ah? Hahaha ..." Haoning and Longfei laughed for a moment, and then they laughed, right? Auntie is not what day is it expected to come every month, but the specific day is really not sure, Hao Ning laughed and exclaimed, "Xiaowen, you are so talented. I have read so many versions of the explanations, and for the first time explained the key factors here as the aunt's. Instead, what is Schrödinger's? Cats, do n’t you understand Schrödinger ’s aunt? "

Xiaowen blushed. After all, she was a girl and a doctor, so she naturally remembered the parts related to herself.

"Okay, Haoning, you continue to say chant." Liu Shuai was embarrassed to see Xiaowen and urged Haoning.

"Got it," Haoning has seen the essence of Liu Shuai's emphasis on color and friendship. "Since everyone understands this little detail, we want to ask a question: This aunt-no, as long as this radioactive element in the box occurs Change, the cat in the black box will die, but the radioactive element in the black box, we only know that it may change in a period of time, then the question is coming, I ask everyone, at a certain time, this cat Is it alive or dead? "

"Huh?" Liu Shuai was stunned. "How could this be known? If this big aunt came, oh no, the radioactive element changed, the cat was dead, if not changed, of course it was alive. So the cat has It may be alive or it may be dead. "

"Good talk!" Haoning nodded. "Then how do you know if the cat is alive or dead?"

"Isn't that simple?" Liu Shuai thought that Haoning was an idiot. "Can't you just open the box and see?"

"Hahaha, that's right!" Haoning laughed. "This is Schrödinger's cat experiment."

"What experiment?" Liu Shuai was confused again. "There is no experiment? Isn't this normal?"

"Yes, you can understand it if you think about it," Ho Ning nodded and continued to ask, "But if you think about this experiment, what you are saying is that when you, the observer, did not observe the cat in this box, Cats are two superimposed states that are both living and dead, but when you start to observe this cat, the two superimposed states of this cat will become a specific state. This is the one I just said Experiments in quantum mechanics, with and without observers, have different results. This is what Schrödinger wants to explain. "

"It's a good talk. Although Schrödinger's original intention was not to explain ... but it was already very easy to understand," Ren Lao nodded and looked at Haoning approvingly. The popular science article should be very good. "

"Uh ..." Hao Ning thought, if the old lady knew that she not only did not write a popular science article, but also wrote some novels on the website, she didn't know what to say. So it was just a modest smile, no words.

"It's so interesting!" Xiaowen continued to ask, "Is there any other fun?"

"This--" Haoning lowered his head and thought for a while, then smiled and asked a question, "Do you know what is the fastest speed in the universe?"

"I know this," Liu Shuai nodded. This was what he learned when he was a child. "It is light, there is nothing faster than light." After thinking about it, I added, "Of course, the legendary Myths are not counted. "

Knowing what he meant, Haoning nodded: "Yes, but there is a quantum entanglement phenomenon in quantum mechanics that seems to be a special case, because even if two entangled quantums are far apart, the state of one quantum changes, and the other quantum The state also changed with it. It is said that this speed is ten thousand times that of light.

"How is it possible?" Xiao Wen opened his eyes wide, his face unbelievable, and shook his head. "This is completely different from what my teacher said when I was in high school. The teacher told me that there was nothing exceeding the speed of light."

"This ..." Ho Ning scratched his head. He couldn't always say that Xiaowen's teacher was wrong, so he had to ask the outside audience for Mrs. Ren.

"Young people are terrible," Ren Lao saw Haoning's face in distress, and nodded with a forgiving smile. "Although some places are wrong, they are generally right. Xiaowen, don't worry about Hooning, he said. It is indeed the fact, but it is not the same speed as you understand. But-- "Ren Lao turned his head and looked at Haoning," The teacher needs to correct a little more, not that the speed of quantum entanglement is ten thousand times that of light, But the speed of quantum entanglement that can be detected now is at least 10,000 times that of light. "

Liu Shuai and Xiaowen were even more surprised to hear Ren Lao say this, but they still didn't ask.

"You don't need to ride or drive a boat, you can travel anywhere in the world; there are thousands of people in the world, and the rocks are rotten and dry as autumn." Ren Lao suddenly chanted a poem and sighed, "This is an ancient novel. The poems describing the gods, talking about our ancient gods, arrive everywhere instantaneously, much like the principle of quantum entanglement. Of course, all the peculiarities of quantum mechanics only exist in the micro world, our macro world , Far less magical. "

"The Great Thousand World must be surprised ..." Liu Shuai listened to his heart stagnation, and couldn't help but feel a little sad. This is a poem describing Yun neutron, that is, Zhang Quan, who only had a big fight two days ago. He hasn't had any until now. Recognized father.

"Hey, old lady, you're good at everything," Chen Lao shook his head, disapproving, "This is the idea that cannot distinguish reality from legend. Modern science is modern science, how can it be related to myth and legend."

"A lot of legends are very useful for reference," Ren Lao tit-for-tat and shook his head. "You are also an open-minded person, how come this is not going to be easy? In the process of quantum scientific research, I doubt this quantum mechanics very much. It has something to do with the generation process of human consciousness-many great scientific conclusions are bold assumptions and carefully tested. "

"Come on, come again," Speaking of Chen Lao's expertise, Chen Lao got up and waved his hand with a smile. "Modern medicine has proved that human consciousness is caused by the synapses of the human brain ..."

"Nerve synapse, synapse, you just can't get through this Kaner-" Ren Lao interrupted Chen Lao impatiently, "How can this simple study at the physical level explain that human consciousness is different?"

"That's because--" Chen Lao opened his mouth and was about to talk, but Ren Lao interrupted again. "Lao Chen head, old lady, I will ask you one of the simplest questions today: you said that consciousness is through the human brain The bioelectrical phenomenon between the synapses of the nerves is generated, so does it mean that if you can know each molecule of the human brain, the composition of atoms, the current state, and the transmission law of bioelectricity, you can know What is this person thinking now, and infer what he will do in the future? "

"This ... of course--" Chen Lao was stunned when asked.

"This question seems to be a paradox?" Xiaowen thought carefully and frowned. "It seems that if we do know the whole composition of a person's brain and the operation of the brain, through high-precision calculations, it is like a formula In the same way, we should be able to know what this person is thinking and what he will do in the future, but how is this possible? I do n’t know what I will think in the future, what I will do next, and how can others know? "

"Yeah ..." Liu Shuai saw Xiaowen thinking about the problem at this time, and also thought about it, and said, "Why is it possible that one's consciousness is not the most clear, on the contrary, others are clearer than him? If there is Personally, without my knowledge, I know what I will do next. Does n’t this mean that the future of my life is all set? ”

Speaking of which, Liu Shuai and Xiaowen glanced at each other, shook their heads, and shook their heads, "Absolutely impossible!"

"This, uh, this ..." Chen Lao is obviously thinking about this problem too ~ www.readwn.com ~ Although he is studying the direction of nerves, he solves concrete problems more pragmatically. As for this kind of ultimate problems involving the physical level , Is really not their main thinking direction.

"This and this, this and this," said Mrs. Ren, slightly angry, and aired, "you can't tell the truth, and I'm not allowed to assume the reason, hey, I said that your old professor really lived in the past. The more you live, the more closed you are.

"I'm shutting down the country?" Chen Lao was blocked by this question without an answer, and when he heard the anger, "well, I'm shutting down the country. When you reform and open up, you can change your revolution and touch the stones to cross the river." Come on! Be careful and rise a few decades ago— "

"You still say!" Mrs. Ren listened to Mr. Chen's words and quickly pointed to Mr. Chen's nose. "Would you like to say that thing again?"

"..." Chen Lao seemed to know that he had said the wrong thing, shut up and said nothing, but he was too angry to speak.

"It's over, it's noisy again ..." Ho Ning felt helpless, but he really didn't know how to persuade. After all, one was not familiar with the two old people, and the two old people were very successful in their fields. If you start persuading hurriedly, most of the two old people will let themselves be judged by their own "speech" in front of these people. In this way, how can this reason be evaluated? At that time, Ho Ning probably understood why Ren Lao was teaching at the university in Pingjing, but Chen Lao was in Chang'an. The two men were so grumpy and academically opinionated. They could stay together for more than a day without quarreling. It is a "miracle" in human psychology, and I don't know how the two people came over for so many years.

"grandparents--"

Xiaowen is preparing to persuade the two elderly people, who knew that a man's voice came from behind, looked back, smiled politely, and yelled, "Cousin."
