Is the "wave function collapse" in quantum mechanics caused by human consciousness?
There is no such thing in quantum physics. This is a topic full of ghosts and gods. It is sheer nonsense for those who say this to pretend that they don't know anything about quantum physics.
Consciousness? Cause the wave function to collapse. Who said that? Did Bohr, Dirac, Heisenberg and Pauli, masters of quantum mechanics, say that? No, did Einstein and Schrodinger, who once worked with the Copenhagen Party represented by the above masters, say that? No, either. Who said that? I originally wanted to use quantum mechanics to summon souls to accept the resurrection of ghosts and gods. Is it some publicity? The end of science is theology? A group of people are screaming.
They use some strange characteristics in quantum mechanics, such as uncertainty principle, wave function collapse, quantum entanglement and other characteristics that are contrary to the logic of macroscopic things to mystify quantum mechanics and lead it to theology.
The debate between Einstein and Copenhagen School. In the last century, there was a great debate about these characteristics of quantum mechanics, that is, the dispute between Copenhagen School and Einstein's classical scientific school. Einstein's point of view is that he admits that quantum mechanics has its own unique laws, but this law can be recognized. The so-called ghost effect of quantum entanglement, uncertainty principle, uncertainty law, wave function collapse and other theories are actually the embodiment of the incompleteness of quantum theory, but there are still some hidden variables in some quantum phenomena that have not been discovered. Generally speaking, there are still some deep-seated laws that have not been recognized. With the development of science, these laws will always be recognized, so that these seemingly unpredictable things in quantum mechanics become predictable and understandable.
Einstein has a famous saying, which means? God can't roll dice? . God here refers to the laws of nature. He believes that the laws of nature are not drawn by lottery, but can be traced back. Einstein's hardcore fan Schrodinger firmly supported his point of view and put forward a? Schrodinger's cat? To satirize the uncertainty law. This debate lasted until the death of Einstein and Schrodinger, and it was inconclusive.
? Schrodinger's cat? Is a typical example of the so-called wave function collapse. Wave function collapse is actually an extension of uncertainty principle and a special phenomenon in microscopic field. Everything in the microscopic field has wave-particle duality, which shows that the position and momentum of particles in space exist with a certain probability, such as the atomic model of quantum mechanics, in which electrons use? Electronic cloud? The way around the nucleus, this is the so-called? Wave function? .
When people measure electrons by physical methods, matter will randomly choose a single result to represent it. When we are not observed, it is like rolling a dice. No one knows what the state is. This is a wave function state. When we are observing, the dice are fixed, showing an idea, so what? Wave function collapse? .
Schrodinger's cat? Thinking experiment is such a setting. He assumed that there was a box with a cat and a bottle of radioactive material in it. The life of a cat depends entirely on whether the bottle of radioactive material decays. If it rots, the cat will die. If it doesn't rot, the cat will live.
The point of view of quantum mechanics is that before the box is opened, the cat is in a wave function state, and no one knows whether the cat is dead or alive. Only at the moment when the box was opened, the wave function collapsed and the cat appeared in an obvious dead or alive state.
Schrodinger's original intention is to use this thinking experiment, irony? Uncertainty principle? Theory. Schrodinger believes that whether people open the box or not, the cat's life and death have been decided, but they don't know until they open it. The conclusion is that the cat's life and death status is not determined at the moment of unpacking.
This is common sense in life, and all people who eat melons know it. If you vote, Schrodinger's view will definitely get more than 90% support. But unfortunately, Einstein and Schrodinger used some macroscopic common sense and logic to apply the phenomena in the quantum field, and later proved them wrong.
In fact, Copenhagen made it at that time? Attack the shield with the spear of the child? Schrodinger wave equation method? Opportunity? Distribution explanation? Schrodinger's cat? . The Copenhagen school thinks that Schrodinger equation can explain the law of particle fluctuation in the default particle eigenstate without observation. However, under observation, the wave function collapses and the characteristics of particles cannot be identified.
De Broglie and Schrodinger jointly established wave mechanics and Schrodinger equation, which are a pillar to describe quantum mechanics and play a vital role in the creation of quantum mechanics theory.
So although Schrodinger was defeated, he was still one of the important founders of quantum mechanics.
It was Bell's inequality that finally proved Einstein wrong. This is American physicist John? Stuart. A mathematical inequality put forward by Bell is a test theory about whether there is a completely local hidden variable. Experiments show that Bell inequality is not valid, which means that there is no local hidden variable theory that can copy every prediction of quantum mechanics, which means that Einstein's prediction of local entity theory does not conform to quantum mechanics theory.
Its mathematical expression is: ∣Pxz-Pzy∣? 1+Pxy
From this point of view, Einstein was really wrong. The root of their mistake is to establish the theory of quantum mechanics with macro theory, and our world does have the characteristics of different logic between quantum field and macro field. The conclusion of Bell inequality has been widely recognized by the scientific community. Since then, the Copenhagen faction has won, and several master scientists such as Bohr, Heisenberg, Dirac and Pauli have become symbols of the orthodox theory of quantum mechanics.
The tiny particle world and the inevitable disturbance of observation are the main reasons for quantum special performance. According to the current quantum theory, the uncertainty principle is mainly based on interference in the process of quantum observation. We know that in our world, especially in the human world, all observation activities need light, no matter whether the object is big or small, we can't see without light.
Light is electromagnetic waves, including radio waves, infrared rays, visible light, ultraviolet rays, x-rays, and? X-ray spectrum, all bands of these electromagnetic spectrum belong to the category of invisible light except visible light.
The uncertainty principle describes the law of particle motion in the quantum world. According to this theory, it is impossible for people to know the position and velocity of a particle at the same time. This is because the uncertainty of particle position must be greater than Planck's constant and follow the inequality:
H is Planck constant: h = 6. 15? 10-34 J？ s
When observing the microscopic world, it is impossible to determine that the position of particles is less than the distance between the two peaks of light. In this way, to accurately measure the particle position, the shorter the light wave, the better. The shorter the wavelength, the stronger the light energy, such as X-ray, X-ray and X-ray. Lei et al. The greater the momentum gained by the particles when these lights shine on them, the greater the uncertainty of measurement.
The uncertainty law is the root of other characteristics of the particle world. Due to the uncertainty and uncertainty of the quantum world, a series of theories such as quantum entanglement and wave function collapse will inevitably be derived from it. Therefore, it can be considered that the uncertainty principle (uncertainty law) is the root of all kinds of strange phenomena in quantum mechanics, and some characteristics of wave function collapse and quantum entanglement are derived from this premise.
The premise is that observation will inevitably disturb quantum, and it is impossible to determine its position and momentum at the same time.
What does it matter? Consciousness causes the wave function to collapse? Have nothing to do with each other
