Quantum physics is the most basic theory about the natural world, which was discovered by humans in the 20s of the 20th century, but still cannot understand the true meaning of this theory. Most people have never heard of quantum at all, and beginners are puzzled, and in fact, all the greatest scientists of the 20th century didn't really understand it and have been arguing about it all the time. However, the more difficult and challenging the questions, the more intriguing human beings are to understand nature and ultimately themselves.
Today, for every modern person who is still curious about nature, without understanding quantum, it is impossible to understand the world around us, and it is impossible to truly become a rational and sound person. At the same time, let's all feel fortunate that it is now easy to truly understand the mysterious quantum, which will make those great people who have passed away envious and heartily gratified.
The discovery of quantum has been called a great revolution in the field of human science and thought, as it will shock the hearts of all those who try to approach her for the first time. It is this real shock of the mind that is lacking in modern man, who is too obsessed with sensual pleasure to ignore the fresh charm of reason.

Quantum is not a concept on microscopic particles such as molecules, atoms, electrons, and protons, and if there is a minimum indivisible unit of any physical quantity, such a physical quantity is quantized, and its smallest unit is called quantum.
In traditional mechanics, our physical quantities are continuous, taking energy as an example, we can ask for 1 joule of energy, we can ask for joule of energy, we can ask for joule of energy, and as long as we are happy, it seems that we can ask for infinitesimal energy (as long as the scientific and technological means are developed enough). But quantum mechanics tells us that it's impossible for you to want infinitesimal energy, because energy is quantized, it has a minimum indivisible unit of energy, and you can't be smaller than that, and all energy is an integer multiple of this minimum energy.
Not only energy, but also many physical quantities are like this, and the mechanical system established based on such a model is called quantum mechanics

Interpretation of quantum mechanics: one of the theoretical foundations of modern physics. Theories that study the laws of motion and their properties of microscopic particles (such as electrons, atoms, molecules, etc.).
Quantum mechanics, as a theory of physics, is a branch of physics that studies the laws of motion of microscopic particles in the material world, mainly studying the basic theory of the structure and properties of atoms, molecules, condensed matter, atomic nuclei and elementary particles, which together with the theory of relativity constitute the theoretical basis of modern physics.
Quantum mechanics: There is a historian de Broglie, who proposed the wave of matter on the basis of his predecessors, that is, not only does light have wave-particle duality, but all matter has waves, which is the wave of matter, but the macroscopic object is not so obvious.
From this assumption, people really entered the temple of quantum mechanics, and then people proposed the wave function to describe the state of particle systems, and the famous Schrödinger equation, which are all useful tools for solving the problem of onlookers.
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.
In the early 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. With the exception of gravity, which is described by general relativity, all fundamental interactions to date can be described within the framework of quantum mechanics (quantum field theory).

Why study quantum mechanics? There are two answers, utilitarian and non-utilitarian.
From a utilitarian point of view, learning quantum mechanics is very useful.
What is the role of non-specialists learning quantum mechanics?
Mastering a certain amount of quantum science knowledge, on the one hand, can increase the conversation after tea and dinner, and show your elegance; Second, it can prevent being deceived.
Human beings live in the universe and are closely related to quantum mechanics. Mobile phones that are inseparable from us, wifi that is essential at home, MRI machines that check the body in hospitals, and laser ...... that do beauty or cuttingOur sense of taste, smell, and other sensory organs function ......Nuclear fusion ...... inside a starAll are based on the basic principles of quantum mechanics. James Kakalios says in the introduction to his book "The Wonderful Story of Quantum Mechanics":
Where is quantum mechanics? Aren't you immersed in it? "We don't know about quantum mechanics every day.

Quantum mechanics is a classical physics discipline. Generally speaking, quantum mechanics is a basic discipline in physics, which is mainly used to study the change law of microscopic particle motion in the world, and is one of the basic theories in physics. Quantum mechanics is the result of the joint research of many scientists, and this discipline embodies the efforts of many scientists, such as Schrödinger and Bohr.
1. The Concept of Quantum Mechanics Quantum mechanics is a type of mechanics, and as the name suggests, it is an important part of physics. It mainly studies microscopic particles, such as atoms and molecules. Quantum mechanics can study their condensation, excitation states, and fundamental properties, and together with the theory of relativity, it forms the theoretical basis of modern physics.
Quantum mechanics mainly includes atomic physics, solid state physics, particle physics and other related disciplines.
2. The development history of quantum mechanics Quantum mechanics is a modern physical discipline, and its emergence is about 100 years ago. At the beginning of the 20th century, quantum mechanics was studied and created by many scientists on the basis of the old quantum theory. These scientists include Planck, Bohr, Schrödinger, Pauli, Fermi, de Broglie, Heisenberg, Einstein, and others.
Quantum mechanics is the result of all the research and dedication of the relevant scientists, opening up a new direction in modern physics.
3. The application significance of quantum mechanics The production of quantum mechanics has great significance and role in modern life and the development of science. It has played a normative role in solid state physics, chemistry, chemical materials and other disciplines. Moreover, in life, there are many devices and technologies that make use of the physical principles of quantum mechanics, such as lasers, nuclear magnetic resonance, microscopy, semiconductor manufacturing, etc.
It has great physical significance for improving people's quality of life and promoting the development of science and technology.

The quantum realm, the limitations of number theory, limits people's thinking. In the new number theory, 1 is equal to the set of infinite numbers, and the set of infinite numbers corresponds to 1 at the same time. Various phenomena known to every scientist, normality and infinity exist at the same time.
It's not that it's unimaginable, it's impossible to express, it's time to build a new number theory.

At the beginning of the 20th century, Heisenberg and others proposed quantum mechanics and used it to explain the motion laws of microscopic particles in the material world. At the end of the 19th century, physics research had already involved the microscopic world, and the classical mechanical theory at that time could not explain the motion characteristics of microscopic particles, so a large number of scientists jointly proposed quantum mechanics.

Quantum mechanics is the key to opening the next world of science and technology; The esoteric theories of quantum mechanics have not yet been fully mastered. One day, when mankind has mastered quantum theory completely, it will indeed be possible to complete the feat of "transforming the world"!
We all know that the people who have made the greatest contribution to the development of human civilization over thousands of years are not those politicians and politicians who often appear behind the scenes; Rather, they are scholars, physicists, and astronomers who keep a low profile and tirelessly explore the boundaries of science.
In the 21st century, the most important discipline in physics is undoubtedly the so-called "quantum mechanics". The so-called "indecision, quantum mechanics", although quantum mechanics sounds "high", the threshold is quite high; But it is also a mantra of many netizens and one of the hot words on the Internet.
What exactly does quantum mechanics do? In the final analysis, this is an inductive science that summarizes the laws of motion of microscopic particles. That's why it's so obscure and difficult to understand with normal logic.
However, the microcosm and the macrocosm have something in common;
Therefore, quantum mechanics can also bring tangible changes to our lives, and even take our overall scientific level to the next level. Facts speak louder than words, and at present, countries around the world have put new technologies such as quantum communication, quantum encryption, and quantum light-speed transition in the top priority.
This is enough to illustrate the importance of quantum mechanics from the side. Some people also think that mastering quantum mechanics can allow human beings to completely transform the world; It is believed that although this statement is exaggerated to a certain extent, it is not untargeted.
After all, the difficulties in quantum mechanics are the bottleneck of our scientific development, and they are also the opportunity for scientific development breakthroughs. For example, once the entrance to the "quantum world" is found by human beings, then the "immortality" pursued by human beings may be realized in a time that is almost stagnant!

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. >>>More
