No. 368 Fu Shichun idealism

When the fake is true, it is also false, and when it is false, it is also true.

This virtual table tennis ball is so real that it is difficult to distinguish the real from the fake. If the light glasses are forcibly tied and not allowed to be removed without permission, if the CR-18 and the virtual game "Table Tennis" and other visual reality devices no longer have special signs on virtual things, the experiencer will definitely misunderstand that he has really obtained a table tennis ball.

This ping pong ball is so real.

This table tennis ball can only be reproduced by high-end black technology in science fiction.

This kind of black technology that shatters the boundary between virtual and reality brings an unrealistic feeling to a group of experiencers.

The CR-18 was too far ahead of its time.

CR-18 brings the shock to the experiencer, as if the Qin Emperor and the Han Dynasty appeared in the Huaguo queue to be shot, as if there was an armored assault in the troubled times of the Ming and Qing dynasties, as if the Internet of Things appeared in the troubled times of the Republic of China, advanced to the point of disbelief, advanced to the point of making people feel absurd of the times. The Spring and Autumn Literature Network imagines the future online game model, either nuclear fusion is realized, and the global human race has nothing to do; Either fly out of Earth and move towards an interstellar era where there is no shortage of supplies, and even with that abundance of productivity, players need to queue up to buy virtual game helmets to play virtual games. And the Spring and Autumn Group is now 20 years away from nuclear fusion forever and only 50 years away from oil stocks, and has come up with more than 100 grams of electromagnetic signal patches with goggle-type optical projection glasses to turn the virtual into reality.

It's so ahead of its time!

Too far ahead to be believed.

Ahead of its time.

If you look closely at the electromagnetic signal patch, it only wraps around the wrist and ten fingers, covering a negligible area. If the electromagnetic signal patch wrapped around the finger can capture information such as electromyography signals, it is still difficult to understand how the CR-18 works, but how can the back of the hand feel the virtual table tennis ball in the palm of the hand that is not covered by the electromagnetic signal patch? The experiencer held the virtual table tennis ball tightly, obviously the whole palm felt the resistance, and the touch of the palm skin and the virtual table tennis ball shell was so clear.

The experiencer throws the virtual table tennis ball upwards and catches it with the back of the hand, and the feeling of the table tennis ball hitting the back of the hand is also extremely clear.

Why can I feel a virtual table tennis ball on the back of my hand that is not covered with an electromagnetic signal patch?

The CR-18 is simply incomprehensible magic.

The gold medal commentator answered the doubts in a timely manner: "Are you curious about the working principle of CR-18, why there is no electromagnetic signal patch on the back of the palm, which can also bring you extremely real feedback on the five senses?" ”

"Before we talk about how the CR-18 works, let's talk about an interesting story about idealism and materialism. Idealism pays attention to the self, everything comes from the conscious thoughts, often said, 'the flowers are red because of me, the grass is green because of me', open your eyes to see the world, the flowers are red and the grass is green, and when you close your eyes to see the world, the flowers are not red and the grass is not green. With the development of natural science, materialists can easily refute the argument that 'flowers are red because of me, and grass is green because of me', because flowers are red and grass are the result of the development of objective things, and are never subject to personal will. ”

"However, materialism is developing, and idealism is developing. When Panyang Normal University split up a number of universities, Fu Shichun, a lecturer at the School of Philosophy of Panyang University, interpreted the universe with mathematics, put forward a refreshing modern idealism, and re-examined the primacy of consciousness. Fu Shichun's idealism believes that abstract logic such as spirit, consciousness, and ideas is the foundation of the world, and that all matter and the objective laws expressed by it depend on abstract logic to exist. ”

"Returning to the sentence 'flowers are red because of me, and grass is green because of me', ordinary people with a little common sense of natural science seem to be able to easily refute it: flowers are red and grass are obviously objective laws, how can it be that because you close your eyes, the flowers are not red and the grass is not green? You think you are God, the natural laws of the universe revolve around you, when you open your eyes, you will see red grass and green, and when you close your eyes, you will not be red grass and green! Practice tells us that 'the flowers are red because of me, and the grass is green because of me' is completely a psychopath's whisper. ”

"However, philosophy is not so simple, and idealism is difficult to completely refute."

"Fu Shichun's idealism stands on the shoulders of natural science research results and reinterprets the phrase 'flowers are red because of me, and grass is green because of me'."

Fu Shichun retorted that research has proved that flowers and grasses are actually colorless. The so-called red and green are both caused by the wavelength and frequency of light, green light has a wavelength between 500nm and 560nm, and a wavelength of more than 605nm is red light. The reason why visible light is visible and the color is red and green is because the photons bombard the retina, causing a photochemical reaction of photosensitive pigments in the photoreceptor cells. To put it simply, we think that the flowers are red and the grass is green, not because the flowers are really green, but because the retinal cells have a photochemical reaction because of the reflected light of the flowers and plants. ”

"Are the photochemical reactions of the retina constant?"

"The answer is no."

"The concept of the three primary colors of light should be well known to everyone. But do lights really have three primary colors? The answer is also no, light is only divided into wavelength and frequency, and there is absolutely no so-called primary color. The three primary colors of light should be said to be the three primary colors of the human naked eye, because there are only three kinds of cones in human beings, long cones that are sensitive to yellow-green light, middle cones that are sensitive to green light, and short cones that are sensitive to blue-violet light. ”

"The three primary colors of light are never physical causes, but biological causes, and the world is purely observed with the human eye. If there were aliens in the universe, if they were also carbon-based life, if they had eyes with a retina structure, if they had two cones or four cells, their understanding of light might be the two primary colors of light or the four primary colors of light. ”

"Going back to biology, is it a fate for humans to have three types of cones?"

"Maybe, but more likely not."

"Reptiles, birds, and the vast majority of subosseous fish are known to have four types of cones that are able to see shorter wavelengths of ultraviolet light. The common ancestor of these three groups of animals had tetrachromatic vision as early as 400 million years ago. The common ancestor of these three groups of animals also happens to be the ancestors of our humans. That is to say, the ancestors of human biology 400 million years ago were actually four-colored visual animals. ”

"Humans are derived from mammals, and mammals are derived from reptiles. A more wonderful fact, except for a few primates, kangaroos and other banded animals, the vast majority of mammals have only two types of cones, when reptiles evolved to mammals, tetrachromatic vision became dichromatic vision, they can not see ultraviolet rays, nor can they see orange and red. What happened in between? ”

"Unfortunately, I don't know the answer."

"At present, the evolutionary history of life on earth is still in its infancy, and there are often some subversive discoveries in the academic community. For example, the image of dinosaurs, the discovery of the 'Chinese dragon bird' in western Liaoning in 1996 completely subverted the theory of the origin of monots. Paleontologists have told us in recent years that some of the dinosaur images depicted in Spielberg's "Jurassic Park" series of movies turned out to be not what dinosaurs should look like at all. Several recent studies have shown that the well-known extinction of the Cretaceous dinosaurs may not have been as serious as thought. What the facts were at that time may still require the continued efforts of academic researchers. ”

"Today, I will only speak of the current popular public opinion."

"In order to escape competition with dinosaurs, mammals were forced to burrow or hunt at night. After tens of millions of years of evolution, the mammalian ancestors slowly lost the other two color visions and became the current dichromatic vision. And our more recent ancestors regained the third color vision because of a genetic mutation by coincidence. After the division of apes, apes inherited trichromatic vision; After the division of the apes, humans also inherited trichromatic vision. ”

"To put it simply, trichromatic vision is not the predestined result of human beings, but the evolutionary result of the survival of the fittest. In my opinion, the current patients with red-green color blindness are both an atavistic phenomenon and a hope to ensure that humans will continue to inherit when encountering the competition of dinosaurs in the new era. ”

"I want to remind you of two main points when I talk about the three primary colors of light: first, the impression of colors such as red and green is the subjective feeling of living beings, and the world in the eyes of two-color visual animals, three-color visual animals, and four-color visual animals is completely different; The second point is that trichromatic vision is not a natural result, if it comes to the era of survival of the fittest, it is acceptable for human eyes to evolve into two-color vision, four-color vision, and five-color vision. ”

"Fu Shichun's idealism put forward the concept of relative idealism, and the objective laws such as the three primary colors are actually the result of human 'idealism' and 'self' observation, and all the colors of the universe described in the three primary colors depend on the idealistic observation to exist."

You may simply refute that the eyes of mammals and reptiles are also objective laws. Unfortunately, such an explanation cannot refute Fu Shichun's idealism, because Fu Shichun has already emphasized that the difference between the human eye and the objective light color is a relative result. If you have to dwell on the material primacy of the eyes, Fu Shichun's idealism completely pulls the topic to the paradox of the brain in the jar. ”

"When I talk about Fu Shichun's idealism, it is not that I believe in idealism, nor does it mean that Panyang University advocates idealism. In fact, in addition to Fu Shichun's idealism, the School of Philosophy of Panyang University has other theories of all kinds, some people support Fu Shichun, and some people oppose Fu Shichun, and the number of opponents is far greater than the number of supporters. ”

"I am here to talk about Fu Shichun's idealism because Fu Shichun's idealism is one of the important guiding ideologies of the CR-18 project team, and almost all of the core mechanisms of CR-18 rely on Fu Shichun's idealism. Only by clarifying the basic concept of Fu Shichun's idealism can everyone truly understand the working principle and future prospects of CR-18. ”
