The theory of quantum mechanics and the theory of relativity are the two basic pillars of modern physics, classical mechanics has laid the foundation of modern physics, but for objects moving at high speed and objects under microscopic conditions, Newton's laws are no longer applicable, and the theory of relativity solves the problem of high-speed motion; Quantum mechanics solves problems under microscopic subatomic conditions. Quantum mechanics believes that under subatomic conditions, the velocity and position of particles cannot be accurately measured at the same time, the momentum, charge, energy, particle number and other characteristics of microscopic particles are discrete and discontinuous, and the laws of quantum mechanics cannot describe the orbital details of particle motion, but can only give relative probability, for which Einstein and Bohr had a heated argument, and derived the famous EPR paradox, and still did not recognize the Copenhagen interpretation of quantum mechanical theory until his death.
Quantum mechanics is a theoretical framework for physics, a revolution in the microscopic realm of classical physics. It has many basic characteristics, such as uncertainty, quantum fluctuations, wave-particle duality, etc., which will become extremely significant at the atomic and subatomic microscopic scales. Albert Einstein, Heisenberg, Bohr, Schrödinger, Dirac and others made important contributions to the development of his theory.
The combination of quantum mechanics and informatics has given rise to a new discipline – quantum information.

Planck proceeds from the classical concept that the energy changes within the system exist in a large number of fixed and separated "quanta". Quantum can be understood as a packet of energy, and the word "quantum" is derived from the Latin word quantum, which means pack. Planck argues that the absorption or dissipation of light and radiant heat from an object is done in a quantum situation, with special energy values depending on the type of energy.
This overturns the previously agreed view that the transfer of light was a continuous process.

Quantum theory means that if there is the smallest indivisible fundamental unit of a physical quantity, then the physical quantity is quantized, and the smallest unit is called quantum.
In the Newtonian mechanics (or classical mechanics) system, the absorption and release of energy is continuous, and matter can absorb any amount of energy.
Later, it was found that in fact, the real absorption and release of energy can only be absorbed and released one by one with a certain order of magnitude (hv) as the smallest unit, h is the most commonly used Planck constant in quantum mechanics, and v is the electromagnetic frequency.
Since Planck's constant is of the order of magnitude small (-34 orders of magnitude of 10), Newtonian mechanics agrees well with experiments on large scales, but deviates greatly on small scales.
Therefore, Schrödinger established the Schrödinger equation on the basis of Planck's quantum theory (the transfer of energy one by one), thus opening up the beginning of quantum mechanics.

The explanation of the term quantum theory is that quantum theory is one of the two cornerstones of modern physics.
The explanation of the words of quantum theory is: quantum theory is one of the two cornerstones of modern physics, and the part of speech is: the structure of the word is:
量 (upper and lower structure) 子 (single structure) theory (left and right structure) Zhuyin is: 一 Pinyin is: liángzǐlùn.
What is the specific explanation of quantum theory, we will introduce it to you through the following aspects:
Idioms about quantum theory.
On the thousands of arguments, the ratio of the same view, the bucket of the bucket, the amount of the car.
Words about quantum theory.
Measure the amount of money, buy the amount of strength, and for the ten Hu measure beads, the difficulty of measuring the weight, the weight of the weight, the weight of the salary, the bucket, the measure of the basket, such as the river and the sea, do not know the measure of the baht, measure the inch.
Sentence formation on quantum theory.
1. The failure of the particle model in relativity, quantum theory and field theory should naturally lead to the failure of the concept of "instantaneous".
2. The old quantum theory is based on classical theory and uses the concept of "orbital" to describe the movement of electrons in atoms.
3. However, although the correctness of quantum theory has been well confirmed in the production of daily necessities, many people ignore its broader and more astonishing mysteries.
4. Do you know who pioneered quantum theory?
5. People don't know how big the universe is on the other side of the Milky Way, and radiant energy, relativity, and quantum theory are even more unthinkable.

Quantum theory is briefly explained as follows:
Quantum theory reveals the basic laws of the microscopic material world and lays a theoretical foundation for atomic physics, solid state physics, nuclear physics, and particle physics. It can explain the structure of atoms, the regularity of atomic spectrum, the properties of chemical elements, the absorption and radiation of light, etc. Planck's constant v in quantum theory is the electromagnetic frequency, which leads to a good agreement with the experiment on a large scale, but a large deviation on a small scale.
Schrödinger established the Schrödinger equation, which opened up the beginning of quantum mechanics.
1. Quantum theory is a theory of physics, which is a branch of physics that studies the motion laws of microscopic particles in the material world, mainly studying the structure and properties of atoms, molecules, condensed matter, atomic nuclei and elementary particles. 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.
2. In the early 20th century, the theory completely changed people's understanding of the composition of matter. In the microcosm, particles are not billiard balls, but buzzing probabilistic clouds that do not exist in more than one location and do not reach point B from point A through a single path.
According to quantum theory, particles often behave like waves, and the "wave function" used to describe particle behavior is a possible property of a particle, such as its position and velocity, rather than deterministic properties. Some of the weird concepts in physics, such as the principle of entanglement and uncertainty, have their roots in quantum mechanics.
