Quantum mechanics can only predict probability, so is it of value to human beings?

The uncertainty principle of quantum mechanics says that we cannot be precise at the same time as the velocity and position of a microscopic particle. The "superposition state" is also introduced, which refers to the fact that a microscopic particle can be in multiple positions at the same time and can also have multiple velocities at the same time, that is, superposition in multiple states. I also introduced the "non-locality" of microscopic particles, that is, if an object wants to have a causal relationship with another object, it can be established instantaneously without geographical restrictions, which is contrary to Einstein's special theory of relativity, but it should also be noted that quantum mechanics also believes that an object with mass cannot exceed the speed of light, and quantum mechanics just thinks that the transmission of some massless information can be done instantaneously, that is, faster than the speed of light.

Then it brings up a problem, the theory of quantum mechanics can only predict the probability that a microscopic particle will be in a certain state in the future, and can never give a definite prediction, so what is the significance of this for us human beings? Many friends think that quantum mechanics only tells me probability, which is tantamount to talking nonsense, we all know that in the macroscopic world, we use Newtonian mechanics to move an object in the future, and every future moment can give a definite result, so quantum mechanics seems to be less powerful than Newtonian mechanics.

But what I want to tell you is that this is not the case, and you must not underestimate the power of probability. Although probability cannot give a definite value, as long as an action is repeated repeatedly, the power of probability will be vividly displayed. For example, if you toss a coin as heads and tails, if you only throw a few times, then it is likely to be heads every time, but we know that the probability of heads is 50%, which means that you throw less times, and the power of probability is not obvious, because everything has coincidences.

But if you toss a coin 1,000,000 times, it basically doesn't happen that it is thrown heads every time, and if you count the number of heads, you will find that the number of heads is about the same as the number of tails, that is to say, the power of probability is displayed, and it is strictly accurate.

So what are the applications of quantum mechanics in our daily life? Its practical toes should know that as long as it is a large number of repetitions, quantum mechanics can be used, because a large number of repetitions can reflect the power of probability. What behaviors are repetitive in large numbers?

For example, the electronic products we use now, as long as it involves the development of chips, due to the large number of 0 and 1 calculations in the circuit, they are basically repetitive work, so transistors and other components will do a lot of repetitive work, we do not need each component to work 100% normally, if a component is broken at a certain time, the rest of the components can automatically fill the loopholes in the work, then the chip can still work normally, so quantum mechanics can play its own huge value in this field.

Very valuable. As the two foundations of modern physics, quantum mechanics plays a very important role in modern human life.

Of course, there is value, quantum mechanics predicts probability, and scientists can continue to study experiments based on probabilities to achieve facts.

Valuable. Because predicting probability is very helpful to mankind, and quantum mechanics has many other uses, it is very valuable to mankind.

This means that, first of all, quantum mechanics itself is self-consistent. Both the five common assumptions of quantum mechanics and the various image theorems derived from them are self-consistent. Einstein and a group of other bulls have been staring at the entire quantum mechanics system to answer, staring at all kinds of mistakes for decades, and he himself is the founder of quantum mechanics, looking for this ERP paradox, and the results of the quantum entanglement phenomenon proposed have been confirmed.

Secondly, quantum entanglement has been confirmed to surpass the basic understanding of physics to a certain extent. If the volatility of electrons is understandable, the uncertainty relationship is also understandable, <>

Conceptual diagram of quantum mechanics.

On the surface, quantum entanglement does have a ghostly "effect" at a distance, and this effect is not the kind of interaction that we think it is. This phenomenon is so weird that I think that although quantum mechanics can make such predictions and does not violate the public assumption of quantum mechanics, it is incompatible with other physical systems, especially field theory. We know that the combination of special relativity and quantum mechanics gave birth to quantum field theory.

However, quantum field theory itself does not explain quantum entanglement, because all field theories, which are recognized by everyone, are currently localized field theories. Therefore, some people put forward all kinds of conjectures and <> when thinking about this spine problem

Einstein-Rosen Bridge.

For example, er=epr, the relationship between the Einstein-Rosen bridge and quantum entanglement. That is, quantum entanglement may work through wormholes. And the wormhole is connected to two entangled black holes.

Finally, for the specific meaning of quantum entanglement, you can refer to Wikipedia or some authoritative physics***, articles written by college physics teachers. If you have the conditions, for example, you can directly take the books of quantum mechanics and read them. Don't be swayed by the mess of news and content—some so-called fortune telling, telepathy, etc., have nothing to do with quantum entanglement.

Because of this, some people believe that after quantum mechanics is proven correct, our lives are meaningless. After all, somewhere in the universe, there might be one more you! Of course, some scientists believe that this may just be a phenomenon in the microcosm and cannot be extended to philosophical uses.

If the theory of quantum mechanics is correct, does that mean that life is really meaningless? How to put it, to understand quantum mechanics, we must first figure out the Schrödinger equation. I was not born in a professional class, and a friend told me that it would be okay to start with the classic proposition of Schrödinger's cat.

In layman's terms, Schrödinger's cat, if you don't open it and take a look at it, and confirm with your own eyes whether the cat is dead or alive, this cat will always be in a state of neither death nor life for you. That is to say, without human consciousness, the state of the objective world cannot be determined. This is a basic description of quantum mechanics.

On top of that, there's an advanced version of understanding. You are in Beijing and have a pair of gloves, but you send them to Beijing and Lhasa respectively. You don't know which glove will arrive in Lhasa beforehand.

If you want to know which glove is from Lhasa, you just need to confirm which one is sent to Beijing. This advanced example is intended to illustrate that there is some kind of connection between all particles, and that this connection is determined by consciousness, and after one particle state is determined, the other particle state is confirmed almost simultaneously. Since it is not a major, it is difficult to understand it later, but the basic proposition of quantum mechanics is to add the confirmation of the state of all things in the world to human consciousness.

Based on the above description of quantum mechanics, let's talk about whether it is meaningless to life. Although I don't quite understand why the subject has such a conclusion, I guess I read some articles on the relationship between quantum mechanics and religion. In fact, if you understand quantum mechanics, you should feel that life is more meaningful.

What can't be changed is the connection between everything, but this connection is not the only one. What can change is what kind of connection you choose to affirm. I don't mean to talk about parallel universes or anything like that, but I just want to explain that from the understanding of the basic propositions of quantum mechanics, we should know that there are many connections between people and the future, and decide which one to choose.

The correctness of the quantum theory does not mean that life is meaningless, but that life is more meaningful to some extent. Life is full of possibilities.

The rights and wrongs of quantum mechanics have no absolute relationship with whether life is meaningful or not.

Even if the above is true, we are the dust in other people's cells, even if we don't exist, but our days are gone? Mortgage not repaid?

Personally, I don't think it's necessary, because quantum mechanics describes the microscopic world, and we are in the macrocosm. The probability of the "randomness" of quantum mechanics in the macrocosm is extremely low, and the macrocosm is still deterministic.

Physics is an experiment-based science, established by respecting the experiments of microscopic particles and adding a few assumptionsQuantum mechanics。These assumptions can be summarized into four:

1. Quantum state space assumption.

2. Quantum state evolution hypothesis.

3. Quantum measurement assumptions.

4. Composite system assumptions.

Quantum mechanics, a theory of physics, is a branch of physics that studies the motion laws of microscopic particles in the material world, mainly studying atoms, molecules, and condensed matter.

matter, as well as atomic nuclei and elementary particles.

The basic theory of structure and properties. Together with the theory of relativity, it forms the theoretical basis of modern physics. Quantum mechanics is not only one of the basic theories of modern physics, but also widely used in disciplines such as chemistry and many modern technologies.

At the end of the 19th century, it was discovered that the old classical theories could not explain microscopic systems, so through the efforts of physicists, quantum mechanics was created in the early 20th century to explain these phenomena. Quantum mechanics has fundamentally changed our understanding of the structure of matter and its interactions. Except for general relativity.

With the exception of gravity, all fundamental interactions to date can be described within the framework of quantum mechanics (quantum field theory).

Quantum mechanics believes that everything in the world is a diffuse wave, and when you observe it, the wave collapses into a point. That is, when you don't look at the moon, the moon doesn't exist, and when you look at the moon, the moon collapses from a wave to the moon.

This goes against the basis of determinism, which holds that the moon is in ** whether you observe it or not.

However, the current experimental data gradually disproves determinism. That is, God rolls the dice.

You can look up the EPR experiment, which is a classic experiment that denies determinism.

I think it's okay, that's a trend, it doesn't necessarily happen 100%, it will change according to the current change, and the trend will change accordingly. Different times may have different results, and if the same result is still the same for many times, then the probability of that trend is relatively high.
