Is there a limit to the world? Wuji pian

is there a limit to the human world? What mankind pursues is that there is no limit, but the world has objective conditions, that is, limitations. Limited by oneself, pursuing infinity.

In the 1-meter race, the fastest speed of human beings has been broken within 1 seconds, but it can still be improved, but it feels almost to the limit.

a gentleman is good at faking things. With the help of horses, human beings can be faster, with bicycles, with cars, with planes and with rockets, and maybe there will be time machines and time ships in the future.

speed, strength, size, accuracy, direction, momentum and energy, how to accurately describe an object?

We are all like blind people touching an elephant, only seeing one side or many sides of things. How can we fully recover and describe things? As Keiko and Zhuangzi argued:

Zhuangzi and Keiko swam on the Hao Liang. Zhuangzi said, "It's fun for minnows to travel leisurely." Keiko said, " you are not a fish, where do you know that the fish is happy?" ？ ” Chuang Tzu said, " you are not me, how do you know I do not know that fish is happy?" ？ ” Keiko said, "I'm not a child, but I don't know the child. I'm not a fish, and I don't know the joy of fish." Zhuangzi said, "Please follow its origin. Confucius said, "You know the fish are happy, but since you know what I know, ask me, and I know it well."

Hui Shi is a representative figure of pre-Qin masters, and he and Zhuangzi are both friends and enemies. The book Zhuangzi records many debates between them, and this is just one of them. This story is very famous and appreciated by readers at home and abroad. Who is right and who is wrong in their debate, who loses and who wins, has always been a matter of opinion. Famous scholars study logic. Logically speaking, it seems that Hui Shi has the upper hand, because people and fish are different. How can people know the psychology of fish? But from the aesthetic experience, Zhuangzi is also reasonable. People can experience any animal's movements, expressions, pain or happiness by observation.

people can observe the experience, but can they really understand the psychology of fish? Can you be 1% sure

is our experience real? Is living a living feeling and experience? Can you create experiences and feelings? Dreamer?

for example, our universe is finite, so what is outside the finite? Is it infinite? If it is infinite, then we can be infinite. Why is it limited?

Like chicken or egg? There is a paradox when there is no difference. What is there?

To quote a passage from Shi Yigong's cognitive limit:

What are we? Think carefully, how do people process information? Let's first define information, that is, matter. We have three levels of matter:

The first matter is macroscopic, that is, what we can perceive and intuitively see. For example, people are a matter, the house is also a matter, and Tiananmen Square and the Forbidden City are all matters.

The second level is microscopic, including things that the eyes can't see, which are also called microscopic. We can perceive, measure and intuitively think that it exists with the help of instruments, such as atoms, molecules and proteins, such as planets ten billion light-years away.

the third level is the ultra-microscopic matter. For this kind, we can only speculate theoretically and verify by experiments, but we never know what it is, including quantum and photon. Although we know that particles can have spins, energy levels and energy, it is really difficult for us to understand them intuitively. This is the ultra-microscopic world. But even so, we still have to think about it. This world is the ultra-micro world that determines the micro world, and the micro world determines the macro world.

who are we? Man is an individual in the macro world, so our essence must be determined by the micro world and then by the ultra-micro world. I have no doubt that I am a Schrodinger equation, a life form and an energy form, but I don't know how to solve this equation, and I don't know how thinking is generated, that's all. I believe, and you should believe, that each of us is not just a bunch of atoms, but a bunch of particles.

Shi Yigong, a gifted scholar in Tsinghua, thinks that there is a limit to human cognition. Many people refute him and think that there is no limit to cognition.

Let's take a look at the recently-hyped Kung Fu Dao, because Ma Yun is on fire, and the cognitive limit is like the realm of martial arts:

On the first floor of martial arts, swords collide, which is determined by the speed of strength. The so-called foreign martial arts, such as fighting between ordinary people, can win with great strength and speed.

On the second floor, the sword is guarded with vigor. The sword is full of dark energy, and the sword can not touch each other. The firm but gentle spirit can be separated from the body within ten feet, such as a master of martial arts, which is called internal skill.

on the third level, the body can break through the space barrier and realize the transition, and the soul can break through the body and realize the wandering away from the soul. You can visit three mountains and five mountains at dusk, and you can go wherever you want.

everything in the world is related, which is known in the known and unknown in the unknown.

The more I grow up, the more I feel humble and insignificant, but perhaps that's the meaning of life. I keep discovering and exploring.
