1. Background: At the beginning of the 20th century, scientists conducted in-depth research on blackbody radiation. Black body is an ideal radiator, which can absorb radiation of all frequencies, and the intensity of radiation is proportional to the frequency. However, the experimental results show that there is a disastrous problem in the ultraviolet radiation part of blackbody radiation, that is, the energy density of ultraviolet radiation tends to infinity.

2. Planck's breakthrough: Planck realized that this problem contradicted people's understanding of energy at that time. In classical physics, energy is considered to be continuously variable, which means that the energy density of ultraviolet radiation should also be a continuously variable value. But if the energy is quantized, that is, it can only take discrete values, then the ultraviolet disaster is no longer a problem.

3. Quantized energy: Planck believes that energy is composed of some basic quanta and cannot be divided. Each quantum has a certain amount of energy, and this energy is discrete and cannot be changed continuously.

4. Mathematical model: In order to explain the experimental results of blackbody radiation, Planck put forward a mathematical model, the famous Planck formula. This formula successfully describes the experimental results of blackbody radiation and shows that energy is indeed quantized.

5. The birth of quantum mechanics: Planck's breakthrough work laid the foundation for the birth of quantum mechanics. His idea of energy quantization completely changed our understanding of energy and became one of the basic principles of modern physics.

The influence of Planck energy quantization on human beings;

1, changing our understanding of energy: in classical physics, energy is considered to be continuously variable, but after Planck put forward energy quantization, we realized that energy can only be discrete, but not continuously variable. This view changed our understanding of energy and opened a new field of physics-quantum mechanics.

2. Promote the development of physics: Planck's breakthrough work laid the foundation for the development of quantum mechanics. This not only solves the problem of blackbody radiation, but also opens up a new road for the development of physics. After that, many physicists began to study quantum mechanics and made many important discoveries and achievements.

3. Influence on other disciplines: The establishment of quantum mechanics has great influence not only on physics, but also on other disciplines. For example, quantum mechanics has important applications in chemistry, biology, materials science and other fields, helping to explain and predict many phenomena.

4. Start a new technological revolution: The establishment of quantum mechanics not only changed our understanding, but also started a new technological revolution. For example, new technologies such as quantum computer, quantum communication and quantum encryption are all developed based on the principle of quantum mechanics, and these technologies have brought a lot of convenience and progress to mankind.

5. Influence on human thought: Planck's energy quantization thought not only changed our understanding of the material world, but also influenced our thinking. It urges us to think about some philosophical issues, such as the nature of matter and the nature of the universe, and these issues have also become important topics in modern philosophical research.
