Who discovered the quantum mechanics of light? Who came up with the quantum theory

The quantum concept is 1900

Planck first proposed, during which it was first proposed by Einstein, Bohr, de Broglie, Born, Heisenberg, Schrödinger, Dirac and many other masters of physics. 20th century.

A complete set of quantum mechanical theories has been established in the past.

It was not founded by one person, but it is generally believed that it was Planck who was the first to establish it.

Extended Materials: 1. Quantum Mechanics:

Quantum mechanics is a sub-discipline of physics that studies the motion laws of microscopic particles. It provides a mathematical description of the "like-particle" and "like-wave" duality of particles (i.e., "wave-particle duality") and the interaction between energy and matter. The main differences between it and classical mechanics are:

It studies the "quantum realm" of atoms and subatoms. Further research in quantum mechanics is the phenomenon of macroscopic matter at very low or very high energies or temperatures.

Two, Planck:

Max Planck

Planck (April 23, 1858 – October 4, 1947), born in Holstein, Germany, was a famous German physicist and an important founder of quantum mechanics.

Together with Albert Einstein, he is known as the two most important physicists of the 20th century. He made another important contribution to the quantum leap of physics with the discovery of the quantization of energy, and was awarded the Nobel Prize in Physics in 1918.

The quantum theory was proposed by Planck.

University of Berlin, Germany, 1900.

Professor Planck first proposed the "quantum theory". On December 14, 1900, Planck published a paper entitled "On the Theory of the Law of Energy Distribution of Normal Spectrum" at the Physics Society in Berlin, proposing the famous Planck Continental-Continental Merger, which is widely regarded as quantum physics.

The day of the birth.

Max planck.

1858-1947) first formed his quantum theory in 1900. This theory is similar to that of Albert Einstein five years later.

Published relativity minds.

The same had a profound impact on physics.

Essentials of quantum mechanics.

Basic description: Wave function. The behavior of the system is based on the Schrödinger equation.

Description, the solution of an equation is called the wave function. The complete information of the system is expressed in its wave function, through which the possible values of any observable quantity can be calculated. The probability of finding an electron in a given volume in space is proportional to the square of the early high trace of the amplitude of the wave function, so that the position of the particle is distributed within the volume in which the wave function is located.

The momentum of the particle depends on the slope of the wave function, and the steeper the wave function, the greater the momentum. The slope is varied, so the momentum is also distributed. In this way, it is necessary to abandon the classical image where the displacement and velocity can be determined to arbitrary precision, and a fuzzy probabilistic image, which is also the core of quantum mechanics.

Quantum mechanics was founded at the beginning of the 20th century by a large number of physicists such as Max Planck, Niels Bohr, Werner Heisenberg, Erwin Schrödinger, Wolfgang Pauli, Louis de Broglie, Max Born, Enrico Fermi, Paul Dirac, Albert Einstein, Compton, etc.

The three laws of quantum mechanics are: the first law of quantum mechanics is superluminal, the second law of quantum mechanics is the gravitational force of the universe, and the third law of quantum mechanics is cosmic theology.

Quantum mechanics leads to three discoveries, discreteness, uncertainty, and correlation with physical quantities. The clock measures time that is quantized and can only take a specific value, and time is discrete rather than continuous. The biggest feature of quantum mechanics is discreteness, and quanta are elementary particles.

The smallest time in the gravitational field is minus 10 seconds for 44 seconds.

Clocks can only measure time periods, and they jump from one value to another in a non-continuous manner. The concept of time no longer exists. Quantum mechanics found that there is indeterminism, and the electrons do not have an exact position, they are in a superposition of positions.

Time considers quantum mechanics, which is also in superposition, and the past, present, and future become uncertain.

De Broglie, Schrödinger, Heisenberg, Bohr and Dirac gradually established and developed the basic theory of quantum mechanics.

When applying this theory to solve problems in the atomic and molecular range, results are consistent with experiments. Therefore, the establishment of quantum mechanics greatly facilitated atomic physics. The development of disciplines such as solid-state physics and nuclear physics also marks the deepening of people's understanding of objective laws from the macrocosm to the microcosm.

Quantum mechanics uses the wave function to describe the motion state of microscopic particles, uses the Schrödinger equation to determine the change law of the wave function, and uses operators or matrix methods to calculate each physical quantity. Thus, quantum mechanics was also known as wave dynamics or matrix mechanics in the early days. The laws of quantum mechanics can also be used to draw conclusions from classical mechanics when applied to macroscopic objects or particles of considerable mass and energy.

When solving certain problems with atomic nuclei and elementary particles, quantum mechanics had to be combined with special relativity (relativistic quantum mechanics), from which the modern quantum field theory was gradually established.

One of the founders of quantum mechanics, the great physicist Albert Einstein.

It is the three subtle aspects of human alayya, that is, the remembrance.

Quantum mechanics was developed on the basis of the old quantum theory. Old quantum theories include Planck's quantum hypothesis, Einstein's quantum theory of light, and Bohr's atomic theory.

It should be Planck.

It should be said how quantum theory was created. Quantum mechanics is one of them, and quantum physics is another philosophy of physics.

At the beginning of the 20th century, physics that had been developed for thousands of years was considered to be very perfect (especially after the development of Newton and others in the previous century), and many physicists at that time thought that future generations only needed to do some tinkering work, but then three major problems appeared, and the physics edifice was crumbling.

For details, please refer to the book "Does God Roll the Dice" in the history of quantum, and I will turn it over when I am bored. The early leaves of the last century were really a good time, but it's a pity that I was born at the wrong time, heh.

The "ultraviolet catastrophe", one of the three major problems, directly led to the birth of quantum theory. The "ultraviolet catastrophe" refers to the inconsistency between the black-body radiation experiment and its theory, there are two theoretical calculations (almost opposite to each other), but the experiment is consistent with each of them in different situations, but not at both ends, so it is necessary to reconstruct the theory.

At this time, there was a man named Planck (who was good at thermalism), even if he calculated and sorted out the two previous theories to get a new result, but it was surprisingly perfect and in line with the experiment. But at this time, even he was afraid, because the "h" used in his formula was a sign of discontinuity, and he couldn't explain it himself, and he wanted to tell the world that he had repented, but the lion had been out of the cage, and he had to carry it hard. Imagine spitting everywhere.

The first is the concept of "quantum", proposed by Planck, energy is quantized, which is undoubtedly the fatal blow of classical physics, not continuous, but quantized! At that time, it was hard to imagine the land difference. Bohr then borrowed the concept of "quantization" (in this case, quantum mechanics) when solving the nuclear model, which was not entirely successful, but it bodes well.

Later, more adventurous physicists took up the burden of the development of quantum physics, and the great Copenhagen School led by Bohr built the main edifice of quantum physics, but the world-famous Einstein kept "opposing" them until his death. But there is no doubt that Einstein played a great role in promoting the development of quantum physics.

That's it, it's hard to tell the story of history.

Quantum mechanics was founded at the beginning of the 20th century by a large number of physicists such as Max Planck, Niels Bojer, Werner Heisenberg, Erwin Schrödinger, Wolfgang Pauli, Louis de Broglie, Max Born, Enrico Femi, Paul Dirac, Albert Einstein, Compton, etc.

Quantum mechanics is a sub-discipline of physics that studies the motion laws of microscopic particles, which mainly studies the basic theory of the structure and properties of atoms, molecules, condensed matter, as well as atomic nuclei and elementary particles. Quantum mechanics is not only one of the basic theories of modern physics, but also has been widely used in chemistry and other related disciplines and many modern technologies. Many physical theories and sciences such as atomic physics, solid-state physics, nuclear physics and particle physics, as well as other related disciplines, are based on quantum mechanics.
