Dragon Clan: Lu Mingfei returns from Sekiro

On the Monyach, Mance and Ye Sheng were adjusting the equipment settings of the speedboat.

Ye Sheng wants to drive this speedboat to pick up Chu Zihang and Caesar.

This task was given to him because he has the "Snake" and can sense the surrounding ships without radar. He can reach the agreed place as quickly as possible without being discovered, and bring Chu Zihang and Caesar was brought aboard the Moniac.

"Professor, Caesar and Chu Zihang said that Lu Mingfei went to Tokyo alone or by helicopter. What's going on?" Ye Sheng adjusted the position of his seat, "It's not like we don't have any in Japan. A stronghold? Where does Lu Mingfei get the authority to mobilize helicopters?"

"Ye Sheng, what do you think of Lu Mingfei?" Mansi pressed the button on the operating panel to check whether the anti-radar device was malfunctioning.

"I think he is a very good person, with an easy-going personality and strong fighting ability. He will definitely be the mainstay of the execution department in the future."

"There are only two of us here, so there is no need to be too taboo. No one knows our conversation. We are all people who escaped together from the bottom of the Three Gorges." Mance pressed a button and the indicator light on the operation panel flashed. "Let me put it another way. Well, do you think Lu Mingfei is a normal person? When I say normal, I don’t mean his behavior and actions."

Ye Sheng was silent. This was a sensitive topic.

But Professor Mance was his mentor. When he entered Kassel, Professor Mance was his supervisor. He was a teacher for one day and a father for life. Coupled with the experience of the "Kuimen Project", he and Professor Mance It can be considered a life-long friendship.

Is Lu Mingfei considered a normal mixed race?

The answer is obviously not. The biggest evidence is the frozen bullets he used in Bronze City. Currently, no technology can achieve this effect. The second is his record of killing the King of Bronze and Fire.

There were many doubts about this battle. Ye Sheng did not notice these before he became the branch director, but after graduation, he stood in a different position and saw different things.

Lu Mingfei entered school in September last year. At that time, it was less than a week before he entered school. The 3E exam had just ended. He obviously had no chance to touch a sniper rifle in the past. There was only one Philosopher's Stone bullet, but Principal Angers Lu Mingfei still gave the only chance to shoot Constantine.

Then came Norton's big fireball. The fireball had already hit the top of the mountain, but it was offset by Chu Zihang's Jun Yan and exploded into a golden rain all over the sky.

But Chu Zihang didn't remember anything afterwards. He fell into a coma when he came into contact with the fireball in Jun Yan's domain. When he woke up, he was already lying on the hospital bed, eating the medical meal Susie prepared for him.

The golden rain was like a cover-up, and no one saw how Lu Mingfei killed Norton.

But these unusual places were blurred by the fiery atmosphere.

Principal Ange asked the students to cheer for the hero, and everyone cheered. No one paid attention to the details, and everyone was enjoying the feast of killing the Dragon King.

Ye Sheng and Shu De Aki were also immersed in the atmosphere. A grand celebration party was held in the school cafeteria that night, and he got drunk at the Victorian-style dining table.

"Ye Sheng, please explain the meaning of BUG in the IT field." Mance turned his head and said suddenly.

"BUG refers to loopholes in computer programs and systems." Ye Sheng replied.

The word BUG originally meant "little bug", but I don't know when programmers began to call the small loopholes that appeared in the system BUG, ​​because these loopholes are as annoying as small bugs. After modifying one, Maybe another one will emerge.

BUG is a product that is outside of the predetermined rules. It is an anomaly that is sometimes incomprehensible.

"Do you remember what my research field is?" Mance said lightly.

"Computers and alchemy equipment design." Ye Sheng responded reflexively. As a student of Mance, he certainly remembered what Professor Mance's research field was.

Professor Manns is a veteran of the Equipment Department, with world-class mechanical design skills, and the computer field is also his deep field.

"Before the birth of Norma and EVA, I had not been exposed to the computer field." Mans said: "The world's first general-purpose computer 'ENIAC' was born at the University of Pennsylvania on February 14, 1946. It was a behemoth. It uses 18,000 electron tubes, covers an area of ​​170 square meters, weighs 30 tons, and can only perform 5,000 operations per second. The computing power of EVA is more than trillions of times that of ENIAC. It is only in the past that we have reached this kind of evolution. Just sixty years.”

"This is a major progress in human history." Ye Sheng said.

"Have you ever played Super Mario?"

"Of course I have. Who doesn't know the plumber in the hat?"

"So do you think Mario's world is real?"

"Mario's world is of course fake. The pixel world is far from the real world."

"That's right, Mario's world was created by humans. The plumber can only move on the plane, jump up and then fall down. He can crush mushroom monsters. He can eat ordinary mushrooms to become bigger, and eat life mushrooms for himself. Adding a life, these are the actions that Nintendo has set for Mario in advance, but when the source code of Super Mario falls into the hands of programmers, we only need to modify a little bit of data, and we can make Mario invincible Yes, let him have infinite life, and any monster that touches him will die immediately."

"Professor, it turns out that you can also use cheats when playing Mario."

"Goldfinger?"

"It's just a cheat code. When you get stuck on a level, someone will use the cheat code. Our generation called it golden finger."

"That's it, but I didn't use any cheats to clear Super Mario. The first time I came into contact with this game, I cleared it in twenty minutes and dug out all its source code."

"Awesome."

"I'm not saying this to show off to you. Besides, what's the point of showing off by clearing a mini-game?" Mance said expressionlessly: "What I mean is that in the era of Super Mario, humans certainly wouldn't feel the need to do so. The world of engineering is real, but when EVA was born, she could simulate a virtual world that was 99% close to the reality of Kassel College, whether it was the light and shadow of the rising and setting sun, or the micro-expressions of students moving in the college , she can achieve perfect restoration, and she has absolute control over this virtual world. She can stop the time of the world at will, make houses collapse, extinguish the sun, and make the world enter an eternal night."

"Professor, what exactly do you want to say?"

"Don't you think the word spirit is similar to something? Since you know about cheat codes, you should know that there are many types of cheat codes. There are cheat codes that make Mario invincible, cheat codes for skipping levels, and of course cheat codes. You can set a cheat to speed up Mario. I can set the acceleration level to be divided into nine levels. The first level is increased by 2 times, and the highest level is 512 times. I only need to send specific instructions in the command box to increase the speed. I You can set a permission, and people with higher permissions can perform higher-level speed-ups. The permissions are randomly selected, and the permissions can also be increased by using the command multiple times."

"Yan Ling·Jia Mo." Ye Sheng murmured.

"The basis of mechanical design is physics. There are two types of modern physical mechanics, classical mechanics and quantum mechanics. You should have learned it in high school. The speed of light is the upper limit of speed and has wave-particle duality. Quantum mechanics has a A very classic experiment is called the Wheeler Delayed Choice Experiment. This experiment is very simple. First, a single-photon light source must pass through a semi-lens. The so-called semi-lens is a semi-silvered lens that reflects 50% of the light. Fifty percent will let the light pass right through.”

Professor Manns said: "If light only exhibits particle properties, then it will follow a 50% probability of reflection and 50% of passing through, but light may also propagate like a wave. If light exhibits wave properties, then It is divided into two parts, which can reflect and pass. During the experiment, a full mirror will be placed on the reflection and passing paths, so that the light sources on the two paths converge on the other half-mirror."

"What is the purpose of this experiment? To prove the wave-particle duality of light?"

"No." Professor Manns shook his head, "Let me tell you the results first. There are two results. During the experiment, a screen will be placed at the intersection of the paths. If the light exhibits wave properties, then interference will occur at the screen. If the pattern exhibits particle characteristics, there will be no interference pattern. What do you think is the probability that the interference pattern will appear?"

"Fifty percent?" Ye Sheng said.

"Totally wrong." Professor Mans immediately rejected Ye Sheng's answer. "Whether an interference pattern appears in the end depends on only one thing, whether someone detects the path of light propagation. If the experimenter is on either of the two paths, Put a detector on the screen to detect the specific path the photon travels, then the photon will immediately show particle characteristics, and the interference pattern that originally appeared on the screen will disappear. If no one detects the path the photon takes, deliberately ignore the photon’s Path information, light will show wave characteristics, and interference patterns will appear."

"Is this photon conscious? If someone looks at it, it will turn into a particle. If no one looks at it, it will turn into a wave?" Ye Sheng felt very confused.

Although the topic was avoided by Professor Manns, he was really puzzled at the moment as to why photons would change their properties due to human observation methods. Even if it was really conscious, how would it know that someone was coming? Observe your own?

It's like you are watching a football match and the ball is kicked out. You are thousands of miles away watching TV, but whether the ball goes in or not only depends on whether you are watching TV at the time. If you are watching, the ball will definitely not go in. Go in, but if you didn't look, the ball must have gone in.

The conclusions drawn from the delay experiment are so outrageous.

"I don't know whether photons are conscious or not, but what I really want to talk about is the next advanced experiment." Mansi interrupted Ye Sheng's thinking, "The experimenter accurately calculated the flight time of the photon, and measured the flight time of the photon on both paths. The detector is placed, and after the photons fly a certain distance, the detector detects the result, and then decides whether to insert a new semi-lens at the convergence point. Because the detector detects the result, the experimenter already knows that light is in the form of particles. The characteristics are still those of waves, and the newly inserted semi-lens has subverted the cause and effect of the entire experiment.”

"The experiment shows that although the time point of inserting the semi-transparent mirror is after the photon passes through the full mirror, it affects the characteristic performance of the photon in the entire propagation process. It is like a football. It originally flew in a straight line, but because you placed it at the end A goal, in this time that has passed, is looked back, from flying in a straight line to flying in an arc.”

"Isn't there an effect first and a cause later?" Ye Sheng felt that quantum mechanics had completely turned into metaphysics.

"It is difficult to explain this phenomenon with ordinary thinking." Professor Manns said: "Before physics developed to the quantum stage, we all believed that it was real enough and that all scientific laws were universal and self-consistent, including classical mechanics. Thermodynamics, electromagnetic theory, etc. are very intuitive and logical. There are no problems at all and it is easy to learn. However, quantum mechanics is very counterintuitive. For example, the wave-particle duality of light means that an object is both a particle and a particle. It's a wave, and whether it's a particle or a wave actually depends on how you observe it."

"The delayed choice experiment allowed us to discover that the real world does not seem to obey the law of causality; photons are identical and cannot be distinguished by numbers. They can be confused at will, and once confused, the phenomena used to distinguish them disappear; and particles automatically Spin, even if a magnetic field is used to distinguish particles with the same direction, but when you further distinguish these particles, they will still be divided into two groups, upward and downward. This world is not perfect and has many loopholes."

"Before I came into contact with the computer field, I only studied ordinary physics and never doubted the reality of the world." Mance said in a low voice: "But then I came into contact with the game world composed of codes, and I discovered that there is a The theory can easily explain the delayed choice experiment. If I want to release a fireball in the game, the probability of hitting the target is 50%. In order to save resources, the game program generally only calculates the result first and then draws the flight animation.

In other words, when my spell is completed, it is determined whether the fireball hits, and then the animation is demonstrated, but from the player's perspective, the fireball is fired first and then hits the monster. At this time, if the player suddenly fires the ball If a new monster is placed on the flight path, then the flight animation must be redrawn and calculated again from the detection point. As a programmer, it is easy to understand this principle, but in the eyes of the player, it subverts the cause and effect. "

"Professor, when you tell me this, do you want to tell me that we live in a virtual world?"

"The probability that we live in the virtual world and the real world is 50% each. In 2003, Nick Bostrom, a philosopher at Oxford University, published a paper in the Philosophical Quarterly, in which he proved that we live in the computer world. The probability is 50%. If you are interested, I can send you the link to the paper." Mansi checked the last button on the console, "Now, let's go back to the original question, do you think Lu Mingfei is A normal person?"

"This" Ye Sheng hesitated for a moment, shook his head and said, "No."

"So don't worry about where his helicopter came from. He is like a bug in our world that cannot be understood with common sense. You should have noticed that Anger concealed Lu Mingfei's identity. "Mansi patted Ye Sheng on the back, the hatch on the top opened, the sun set, and the mechanical arm lifted the speedboat, "Go pick up Chu Zihang and Caesar, don't worry about the unnecessary things, everything will end smoothly. "

Ye Sheng looked at the sky blankly and was lifted out together with the speedboat.

Mance watched him go, turning back into the darkness.

What he missed was that Nick Bostrom was not a hybrid, so he did not include the spirit spirit or any dragon-related factors when verifying the thesis.

Fifty percent is not fifty percent. Lu Mingfei is indeed a bug, but he may also be the person who created the bug.

(Bostrom's paper is called "Are We Living in a Computer Simulation?" There are also delayed choice experiments. Interested book friends can search it on their own. In addition, this article is just a science fiction, please don't believe it.)
