Chapter 110 Schr?dingers Period (1/2)
Chapter 110 Schrödinger's Period
What a lechery baldy! Hao Ning despised Liu Shuai in his heart and continued to speak, ”That's right. When we discovered this phenomenon, many physicists did not believe it, because it did not make sense logically, and it's also completely different from the experiences we had in real life. So, this guy, Schrödinger, did a famous thought experiment, Schrödinger's cat. ”
After saying that, everyone looked at Hao Ning, and even Long Fei, who was a nuclear physics doctor, looked at him. Hao Ning felt a little awkward, he stopped for a moment, and asked Miss Ren: ”Teacher Ren, was my description correct?”
”That's what it means.” Teacher Ren said with a smile and nodded. ”Some small details, such as this so-called observer is not an intuitionistic observer, but it is too complicated, we can understand without details.”
Hao Ning was secretly amused, ”Actually, that's all I know, I really can't explain it if you ask me to.” Seeing that he could fool others, he continued to speak, ”Schrodinger said that if there was a black box, and inside the box, there was a cat, a bottle of poison and a radioactive element. When the radioactive element decayed, this bottle of poison would kill the cat. Otherwise, the cat should be alive.”
”What is decay means?” This time, it was Wen who asked.
”Err …” It was not right to make a joke with Wen, so Hao Ning scratched his head and thought for a while, ”You can understand it as a special kind of change, this change is special. You will know that it will happen within a period. For example, it will happen in a week, but no one knows the exact time.”
”It'll happen in a week, but no one knows the exact time….” Wen frowned, and subconsciously said, ”Why does it sound like having a period ….”
”Ah? Hahaha...” Hao Ning and Long Fei were startled for a moment, and then immediately laughed out loud. It's quite true that every woman had a period timetable, but no one could tell the exact date. Hao Ning laughed as he praised, ”Wen, you're a genius, I've read so many versions of the explanation, but this is the first time I've heard someone described the key factor as a period. In this case, it seems like the theory should be called Schrödinger's period rather than Schrödinger's cat to make everything crystal clear, right?”
Wen's face reddened. She was a girl after all, and a doctor, so she would naturally think of something related to her.
”All right, Hao Ning, go on.” Liu Shuai saw that Wen felt embarrassed, so he urged Hao Ning to go on.
”Got it,” Hao Ning had seen through the real character of his friend Liu Shuai: girls first, then friends. ”Since everyone understands this small detail, we should think of one thing: The period…oh no, as long as the radioactive element in the box decays, the cat will die. However, we only know that the radioactive element in the black box may decay in a period. So here comes the question, can anyone tell the cat is alive or dead at a certain moment?”
”Hmm?” Liu Shuai was startled, ”How can anyone know that? If the period comes, oh no, this radioactive element decayed, the cat is dead, if not, it's alive. So the cat can be alive or dead. ”
”Well said!” Hao Ning nodded, ”Then how do you know if this cat is alive or dead?”
”It's easy.” Liu Shuai thought that Hao Ning was an idiot, ”Why don't you just open the box and take a look?”
”Hahaha, that's right!” Hao Ning laughed, ”This is Schrödinger's cat experiment.”
”What experiment?” Liu Shuai was confused again, ”There's no experiment at all! Isn't that normal? ”
”That's right, it's reasonable if you think that way,” Hao Ning nodded, and continued to ask, ”But what this experiment means is, when an observer like you does not observe the cat in the box, the cat could be considered as both alive and dead. It's a superposition. However, when you start to observe the cat, the superposition of the cat will change into a specific state. This is the quantum mechanics experiment I was talking about. With observers or not, the results are different. That's what Schrödinger wanted to explain. ”
”Well said. Although Schrodinger did not intend to explain... However, it's already straightforward to understand,” Miss Ren nodded, looking at Hao Ning in praise, ”It's effortless to understand, and you can also get the key point. If you write a scientific article, it will be perfect.”
”Err …” Hao Ning thought to himself, if the old lady found out that he had not written any scientific articles, but some novels about gods and ghosts on the website, she might say something else. Thus, he only smiled humbly without saying anything.
”How interesting!” Wen was still a little unsatisfied and continued to ask, ”Is there anything else that's interesting?”
”Um —” Hao Ning lowered his head and thought for a moment, then asked a question with a smile, ”Does anyone know the fastest speed is in the universe?”
”I know this,” Liu Shuai nodded his head, this was something he had learned when he was young, ”The light, there's nothing faster than light.” After saying that, he thought for a moment and then added, ”Of course, the mythical stories don't count.”
Hao Ning understood what he meant and nodded his head, ”Yes, but in quantum mechanics, the quantum entanglement phenomenon seems to be a particular case. Because even two entanglement quanta are very far apart, if one quantum's state has changed, the others will also change. It's said that this speed is ten thousand times faster than light.
