Basic Concepts of Quantum Mechanics. Historical Origins

Chang Lin

The paper has analysed the origin of wave-particle dualism of quantum mechanics with historical viewpoint,and the process which was determined.It has pointed out the structure contradiction of quanyum theory in initial stages,and considered that we should properly understand the physical meaning of wave-particle dualism in the system of modern quantum mechanics.It cannot come into existence as the core basic condition of quantum theory and longer,merely is a sort of classic analogy of localization meaning.However,it is anything but a sort of constitute principle of universality.

The historical development that led to the modern concept of amplification and losing without inversion is reviewed. The two basic mechanisms for amplification without inversion and their theoretical formulation are discussed. Finally, the three experiments that confirm the occurrence of these effects are described.

The introduction of the notion of wave function in quantum mechanics was historically done in a progressive manner, beginning with the original idea of “pilot wave” introduced by de Broglie and finishing with the interpretation of Copenhagen School. One returns here to the historical sources of this concept in order to know better its evolution along history. One believes that this method will allow understanding better the importance of the right interpretation of quantum mechanics. This study has also an educational objective in the sense that it will allow to discuss the opportunity of introducing the teaching of science history in the university programs for the future physicians, engineering physicians and teachers in high schools.
