Liao Qianhui said: "What do you think is the principle of heat distribution in stones?"
Duan Zhu said: "What I think is a kind of mapping. This kind of mapping allows the stone to directly control the status of each point, or detect the status of each point. It does not require a large number of controllers and sensors."
"Mapping" is a broader mathematical concept than a function. It is a certain correspondence relationship between one set and another set. That is, if f is a mapping from set A to set B, then for any element a in A, there is a unique element b corresponding to a in set B. We call a the original image and b the image. Written as f: A→B, the element relationship is b = f(a).
"I'm not talking about a mapping in mathematics. I'm talking about a mapping from real space to space."
Liao Qianhui said: "Is it a kind of mirror reflection? When you look at the thing in the mirror, isn't it exactly the same as reality? It is also a kind of reflection."
Duan Zhu said: "But this is an optical phenomenon, not two actual regions and substances."
"It's like the image of an object is projected onto the screen through the objective eyepiece. Optical transformation."
I remember they originally discussed the principle of this stone. Wu Tian said: "Is the mapping you are talking about somewhat like quantum communication?"
Optical quantum communication is mainly based on the theory of quantum entanglement states and uses quantum transmission to achieve information transmission. First construct a pair of particles with an entangled state, place the two particles on both sides of the communication, and jointly measure the particles with unknown quantum states and the particles of the sender, then the particles of the receiver will change instantaneously and change into a certain state. , this state is symmetrical to the changed state of the sender's particles, and then the jointly measured information is transmitted to the receiver through the classical channel. The receiver performs a reverse transformation on the collapsed particles based on the received information, and the result is the same as the sent one. The exact same unknown quantum state. In order to carry out long-distance quantum state teleportation, the two places communicating must have the maximum quantum entanglement state at the same time. However, due to the influence of environmental noise, the quality of quantum entangled states becomes worse and worse as the transmission distance increases.
Duan Zhu said: "But I think it's not entirely true. Quantum communication is point-to-point communication, with a sending end and a receiving end. Then this communication mapping is communication between one area and another area, and it is one-way. The sender has many points. The receiver has many points. The sender sends the data and reaches the receiver at these points. But the receiver cannot send the data back. There is a difference. It is multi-point. Point-to-multipoint communication, and one-way.”
Wu Tian said: "And it's not just communication, it can directly control these points. It is equivalent to a communication module, plus some control modules, such as some switch control and analog control."
For example, if you want to control the temperature of each point in a certain area. Then it may be necessary to place an air conditioning and ventilation device, but this can only roughly control a certain area and cannot guarantee the temperature of each area. Moreover, the temperature between each area is also continuous, not disconnected.
If you want to control the temperature of each small area, you need to place many heaters, coolers, and communication devices.
Perhaps these devices have been miniaturized.
But it's not right, because there is nothing else placed in the temperature-controlled area.
Perhaps this thermal distribution stone is near the Pillar Mine, but the affected area involves nearby coal mining areas. There is no receiving device placed in the coal mining area.
Duan Zhu said: "I still think they have established some connections in advance. Then the stone that issues the control command can transmit the signal to the controlled area. But how is this connection determined? Maybe the geographical information of these areas has been This stone was input, but it is just a stone, and I can’t see any controller inside. I just don’t know how to input it.”
Liao Qianhui said: "I guess it may be direct voice input."
Duan Zhu said: "Maybe there is another stone in the controlled area, one is the stone that sends the signal, and the other is the stone that receives the signal."
Liao Qianhui said: "Then what is the use of this thing?"
Duan Zhu said: "This function is like an air conditioner. If the room is too hot, you can adjust it to cool it down. If the room is too cold, adjust it to heat it up."
Liao Qianhui said: "If the temperature drops, it can be used as a refrigerator, and if the temperature rises, it can be used for cooking."
Duan Zhu said: "But energy does not come out of nothing. If enough heat is accumulated, then this heat must be extracted from other places."
Liao Qianhui said: "But this is heat that seems to come out of nowhere. Can it be used for heating and providing energy?"
Duan Zhu said: "I am still more concerned about this mapping issue. How to achieve large-area point-to-point information transmission and data correspondence."
"Just like a projector, the signal is originally on the computer screen, and then the information can be completely projected onto the screen through the projector."
Here the digital signal is converted into an optical signal. The digital model is simultaneously converted into a light signal on the computer screen and a light signal on the projector.
In the original understanding, only one device can control another or several devices. So this device is macroscopic and relatively large. But at the microscopic level, people are not familiar with how one particle controls another particle, or several particles, or multiple particles control multiple particles.
Can you think about it this way, these particles are themselves a device, and they also contain more subtle things.
These particles themselves are heaters and cooling devices, and can then heat, cool, and transfer heat to many points.
Then this kind of communication rules may have been written into these devices in advance.
The stone moves upward, downward, left, right, and flipped, which corresponds to different heat distribution relationships.
There may be others as well. Control commands are written into the device, so the stone can be manipulated. Sure. The heat distribution corresponding to each action determines which area it can connect to, the location and size of this area.
Liao Qianhui said: "Then where is the control command writing device?"
Duan Zhu said: "It's too troublesome. Let's go out for a walk and relax."
Liao Qianhui said: "Yes, take advantage of the weekend. Check out the theater and walk around the lake."
