Can the electron double slit interference experiment show that the world is idealistic?

Electron double-slit interference.

Experiments do not prove that the world is materialistic at all.

It's still idealism.

Target. In fact, after the nineteenth century, philosophy no longer debated the question of "materialism" and "idealism". We all know that for the development of the entire human civilization, the greatest discovery is modern science.

Before the advent of modern science, humanity was still in a state of confusion, and data showed that our productivity had stood still for thousands of years; After modern science, we have changed dramatically in all aspects. It can be said that so far, our abundant life depends on scientific and technological breakthroughs.

Of course, with the rapid development of natural science, many experiments and phenomena that subvert our inherent common sense continue to appear. For example, "quantum mechanics," which is the most difficult and obscure for humans in the macrocosm, was once one of the biggest problems that plagued us.

The study of quantum mechanics began in the 19th century with the 'electron bimodal interference experiment'. Through this experiment, the scientific community discovered a rather frightening phenomenon: the existence of an electron depends on whether or not humans observe it.

When we don't observe it, electrons basically have electromagnetic waves.

Quality; When humans observed it, electrons existed in the form of particles. At the time, this left many scientists dumbfounded. Some people even believe that extraterrestrial civilizations may live in a world of particles.

It is they who control the changes behind them; Of course, this was immediately falsified. Subsequently, quantum mechanics gradually came into being; Finally, the Copenhagen interpretation.

Dominating the mainstream, we recognize the existence of microparticles in nature that are "both dead and alive".

Does this prove that the world is idealistic or materialistic? To be honest, no. After the development of philosophy in modern times, "materialism and idealism" are no longer the main disputes, and the so-called idealism is the belief that the world is a "world of appearances", which is fundamentally different from what everyone learns in high school textbooks.

After the nineteenth century, no one talked about whether the world was idealistic or materialistic.

Is the world real? Can the electron double-slit experiment really confirm that the universe is all fake?

The electron double-slit interference experiment has allowed human beings to see the existence of rationality, which is completely opposite to classical matter. Reason is existence, and existence is reason. Rationality is the only law that runs continuously in time, and it is all possible states in the whole space.

Matter is the exact opposite. The laws of matter in time can be changed, which makes matter changeable; In local space, it is only a possible state.

The double-slit interference experiment proves the full-space existence of microscopic particles, and proves that their essence is rational existence, non-local point-like existence.

Rationality is constant over time. If we want to represent the eternal nature of a substance with an unchanging essence, it must be reason, not the appearance of matter, the chemical-physical properties that human beings see.

The understanding of rationality within matter, human beings have only just begun. The laws of physics are just a few of the many rationalities in this universe, and the future will be the era of the great explosion of reason. Rationality cannot be directly observed in experiments, it is hidden under spatial phenomena and guessed by human rational thinking.

Rationality is not directly observable. Reason, also known as the Tao. Tao is more important than matter, but it is more difficult to describe.

With rationality that neither words nor words can describe, human beings invented mathematical symbols. In the future, only those who understand mathematics will know the rules behind the occurrence of anomalies such as double-slit experiments, which are completely opposite to macroscopic phenomena.

In the next era, reason reigns supreme.

What is the electronic double-slit interference experiment, which is known as a scary reflection and a change of worldview, to be done, and how is it weird?

To be honest, the double-slit interference experiment did have a big impact on my worldview. Actually, this experiment is very simple, but the difficult thing is that you have to learn to look at the microcosm without the concept of the macrocosm. The double-slit experiment is essentially a natural phenomenon, and in the past, we were accustomed to conforming the phenomenon to an existing empirical framework, but this time we are building a new experience to conform to the phenomenon.

But I have to admit that the latter is the most commonly used way on the road of science. <

Double-slit interference experiments are divided into two categories, the first is about the interference of light, and the second is about the interference of electrons. I'll give you an example in my non-rigorous language: Let's say I'm a particle in this experiment, and when the experiment starts, I really feel it passing through one of the cracks.

But later, under the same conditions, I could do another experiment, and I might have passed through another slit. That is, a definite cause produces an indefinite effect with a probability distribution. Even if I hit my head against the wall, there is a certain probability that I will pass through the wall.

Under the same conditions, if you do another experiment, the results of the observed and unobserved experiments will be different. Strictly speaking, it only takes "information transfer" to occur, and it does not necessarily require human involvement. In 1979, physicist John Wheeler first proposed the "quantum delay choice experiment" at the conference.

The results show that even delayed observation can affect the process. In other words, I have already passed through a certain gap, but whether or not I am observed behind it will affect which gap I have passed through before. In addition to proving that the law of cause and effect has changed from deterministic to probabilistic, this experiment also wants to prove that the future can determine the past.

It's really scary to think about. <>

Strictly speaking, for microscopic particles, they do not have the concept of "flight", "trajectory", or "passing through a gap". It is described in terms of probability density distribution, that is, the probability distribution of a physical quantity detected at a certain place and at a certain time. The interference fringes that you see are a macroscopic representation of this probability distribution by a large number of particles.

For you, that's an obstacle that leaves a gap. And what are the obstacles for microscopic particles? And what is a sew?

In fact, it is just the corresponding probability. <>

It's definitely an experiment to subvert the worldview. The presence of an observer can influence the outcome of an experiment, and it's scary to think about. The human possession of knowledge does not feel able to explain this result at all, and it feels incomprehensible.

I studied physics myself, and I have done this experiment myself, so seeing this experiment, my worldview has not been subverted.

Because to say this is to challenge our sense of authority, and it is a thing that is not believed.

Because it does give us a better understanding of some of the very unique properties of light.

These individual emitted electrons are seen during the experimentIt's like an all-knowing elf, which makes people feel creepy.

Physicists are surprised and strange that electrons are real solid particlesBut why is there such a fluctuation? Is it because there are multiple electrons in a beam of electrons, and the electrons will interfere with each other, so the interference phenomenon occurs? If the above reasoning is correct, during the experiment, only one electron is ejected at a time, and it is guessed that this phenomenon will not interfere.

That's what makes it creepy, and a miracle just happens,In their experiments, they made sure that only one electron was emitted at a time, but in the end, interference occurred。With the birth of quantum physics, people went deep into the world of particles, and physicists changed the double-slit interference experiment of light from light particles to electrons, and repeated this experiment. Physicists inject electron beams through small holes in the front plank, so that the electrons probabilitarily pass through the double-slit plate behind the hole, and finally fall into the screen behind.

In fact, Einstein will always believe that everything is his own law, and believe that "God doesn't roll the dice."。Schrödinger, a physicist who was also opposed, put forward a thought experiment of "Schrödinger's cat", believing that it was as absurd as saying: "A cat is dead and alive".

However, Bohr insists that the particle world is the existence of uncertain and probabilistic superposition, which is indeed different from the absurdity of the macroscopic world, and that particles obey the probability law of the wave function, and observation will lead to less ideal.

After countless experiments and verifications, temporary victories and small achievements have been achieved. Although it is not ideal, there has been a new breakthrough.

This is because the results of the electron double-slit interference experiment overturn the previous theory.
