V11.chapter 15

"I think it's necessary for me to know more about quantum physics," Kexun sighed. "I never thought that a painting dominated by gods and ghosts should talk about science. Is that funny?"

Mu Yi Ran's water had dried up. He put on his clothes again and pointed to the void on his finger: "particles are the smallest and most basic unit of matter. All matter is made up of particles. Some physicists believe that micro particles have wave particle duality. Light, for example, has both wave and particle properties

Ke Xun nodded: "this part is clear."

"Here we have to mention the experiment of double slit interference of light. Did you learn it in school?" Mu Yi asked him.

Ke Xun scratched his head: "you know, I have scored 13 points in physics, and these 13 points are all derived from multiple choice questions In physics class, I basically read comics or went to sleep. Now looking back, I can only remember the rosacea on the physics teacher's face... "

Mu Yi Ran shook his head a little helplessly, reached out and pinched Kexun's back neck, then kneaded the dog's head: "light is composed of photons, photons are also particles.

"The double slit interference experiment is to put a candle in front of a paper with a small hole opened, and then put a piece of paper B behind paper A. on paper B, there are two parallel and vertical slits on paper B, and a screen is placed behind paper B as a screen.

"Light comes in through the holes in paper a, through two slits on paper B, and then onto the screen. What do you think is the shape of the light spot projected onto the screen? "

Ke Xun said with a smile: "if you ask me this question, I know that the answer is certainly not what I thought, but let me answer it. According to the habitual thinking of ignorance and learning dregs, two long and narrow light spots, like the slits on paper B, are projected onto the screen."

"Light is made up of a lot of light particles. Indeed, according to the usual idea, a pile of light particles will drill through the gap and form two long and narrow columns of light and then project them onto the screen." Qin CI interposed.

Mu Yi nodded his head and then said, "however, what actually appears on the screen is a light stripe similar to a fence, with alternating light and dark. This kind of light stripe is caused by the superposition of different brightness of light. This phenomenon of superposition of different brightness is also caused by the "interference" and "cancellation interference" of "waves", which is the phenomenon of double slit interference of light.

"This phenomenon and experiments have proved that light has both the properties of particles and the properties of waves - because" waves "have the phenomena of" constructive interference "and" destructive interference "- that is to say, light has" wave particle duality ".

"But this experiment is not over. In order to further observe this phenomenon, scientists have used scientific equipment to observe at the micro level, so as to find out how photons interfere through two slits.

"So the incredible thing happened. When people use scientific equipment to observe, the interference phenomenon of light disappears. What appears on the screen is two long and narrow light stripes, and those light and dark grating stripes don't appear. At this time, light seems to recover the single property of particles.

"After that, the researchers did a third experiment, this time by replacing photons with electrons, and only one electron was emitted at a time.

"According to common sense, it is impossible for a single electron to interfere, because the so-called interference requires at least two or more numbers. So what is projected on the screen should be a single particle state.

"However, the result is still unexpected. The interference phenomenon of a single electron has occurred.

"It makes people very confused, who is the interference of individual electrons? How can a single electron enter two slits at the same time and interfere? "

When talking about this, Kexun and Qin Ciqi had a violent attack.

"Lying trough..." Kexun rubbed his arm, "what's the situation? It's a scientific phenomenon. How can it sound a little Think it over and fear it

"The electron is also a particle. It is already the smallest individual and unit, which means that it can not be divided into two parts. It can only be the only one. However, how does it pass through two gaps at the same time?" Qin Ci's eyes were full of wonder.

Mu Yi Ran looked up at the void above his eyes: "in order to know the answer to this question, the researchers installed cameras in the originally sealed equipment to observe how the single electron interferes through the double slit at the same time.

"Next, the bizarre thing happened - after installing the camera, we did the same single electron double slit interference experiment, and the interference phenomenon disappeared. After taking out the camera and doing it again, the interference phenomenon appeared again.

"Such repeated experiments, no matter who does it or where it is done, all the results are the same, that is, when the camera is installed, the interference disappears; when the camera is removed, the interference phenomenon appears.

"In other words, when we don't look at it, it's in a state of superposition of particles and waves, and when we look at it, it appears as a particle. It seems that our observation affects the result. Only when we make the behavior of "observation", will it collapse from the state of superposition of wave particles into the state of particles."So the scariest thing about quantum mechanics is that particles, like conscious people, can see our behavior. As long as we are looking at it, it can detect it, and therefore show different results.

"So the problem is that all matter in the universe is made up of particles, and the state of particles is determined by their consciousness. So, is everything in the universe determined by matter or by consciousness? Is it objective or subjective?

"Whose consciousness are these particles? Who is the subjective of the universe?

"In this world, is there material or consciousness first? This consciousness - whose consciousness, after all? "

"Lying - Sleeping trough! what the fuck! I'm scared to death Kexun took a step back, covered his chest with one hand, and looked at Mu Yiran in horror, "Yiran, are these really scientific conclusions in the real world?! Isn't it really made up in some science fiction movies? "

Mu Yi Ran dragged him to himself - he jumped back and stepped on the iron plate, and then looked at him calmly: "what I said is the scientific theory in the real world, but it can't be called" conclusion "for the time being. After all, there are still too many mysteries in the field of quantum mechanics, but this theory of consciousness does exist."

“…… I'm really scared to death, "Kexun grabbed Mu Yiran's hand and rubbed his chest." after living for more than 20 years, I was suddenly told that the universe might be created by an unimaginable living consciousness. It has subverted my cognition for a small part of my life. I, I, I, I have been completely reshaped and my world outlook has been completely reshaped

"Before I started painting, I always firmly believed in materialism, but I always sneered at anything about gods, gods and ghosts. Even if I came across the painting event later, I never thought that its behind the scenes power could be superior to the laws of the universe. As a result -

" now, a theory tells me that there may really be a creator in this universe ？！ Is it - is the power behind the painting and it is of the same magnitude?! Then we still struggle for a fart... "

"Kirsch, calm down." Mu Yiran held Ke Xun's cheeks in his hands and told him to look at himself, "what kind of existence is the power behind the painting? We should not think about it now. The most important thing is to find the clues of signature from the scientific theories closely related to the painting, and let us leave the painting first."

"Good, good You wait for me. I'll be calm. " Kexun leaned over and took a few deep breaths.

Mu Yi Ran turned his head and looked at Qin CI. He seemed to be a little bit unable to accept it. There was still a sense of horror on his face. The whole person was frozen in place.

"I know..." Qin CI swallowed his throat and began to speak with difficulty, "why do people who study physics are crazy Today, I feel like I'm going crazy just because you know something about it. Those who know more about physics will encounter more confusion and more incredible things than I can imagine. Maybe every day I feel like I'm going crazy. "

Kexun turned around and wiped the sweat that might be hot or startled on his forehead, and said, "let's not care whether those people are crazy or not. Let's just say that in front of us - since all matter in the macro world is made up of a large number of micro particles, what kind of quantum superposition state does macro matter have

"This involves the two schools of contention in quantum physics as mentioned by Haowen Mu Yi Ran said, "if the macro world, like the particles in the micro world, has a variety of uncertain states superimposed, it means that the macro world is not regular and completely determined by random events, because it can not be determined and can not be accurately measured. All possibilities are only a probability, not an accurate value. Einstein and Schr? Dinger did not agree with this view, so the "Schr? Dinger's cat" theory was born. It was used to satirize the so-called macroscopic "quantum superposition state" and "uncertainty" or "uncertainty" theory

"So, is this formula in favor of quantum superposition states in the macro world, or, like Schrodinger, satirizing this theory?" Qin cining eyebrows.

Mu Yiran's eyes were slightly deep and his voice was a little slow. He said, "in fact, before the accident of the son of formula, in the world's top scientific and technological academic journal Nature, some scientific researchers said that they had realized the Schrodinger cat state of many particles through technology, that is to say, they basically realized the quantum superposition at the macro scale Additive state. "

Qin Ci and Ke Xun were shocked again. Qin CI said, "so you mean that the program recognizes the quantum superposition state of the macro world? The title of the painting "Schrodinger's cat" is not antonymy, but means that the program believes that the "Schrodinger cat" state can exist in the macro world? "

Mu Yi Ran nodded slightly: "yes, I think so."

"So..." Kexun rubbed his hair on the back of his head. "We who are in the painting he created are likely to be influenced by the consciousness in his painting. At this moment, we may really be in a state of both life and death?"
