A Historical Overview Of Molecular Beam Methods And Nobel Prize Experimental Research Based On Molecular Beam Method

In the new period,in order to cultivate new talents in line with socialist modern countries,the Party Central Committee attaches great importance to school education.In teaching,teachers should not only pay attention to the transfer of scientific and cultural knowledge,but also strengthen the cultivation of students' various abilities.In this context,more and more physics teachers will pay attention to adding physics history in classroom design.The reason is: First,the history of physics is a science that records the laws of the generation and development of physics,which is an important part of physics.It is one of the teaching methods to select,study and organize the history of physics in combination with teaching content.Second,the intuitive and interesting characteristics of the history of physics can make up for the shortcomings caused by the complexity of physical knowledge,effectively stimulate students' interest,and strengthen students' understanding of physical knowledge.As far as the college physics course and teaching we study,considering the sense of the times and the interest in research,we focus on the selection of the history of physics in modern physics.Through deep analysis,we find that the molecular beam method is not only the main experimental method for people to understand microparticles and explore the micro world in the 20 th century,but also a powerful means for physicists to directly demonstrate the theoretical assumptions of fundamental importance in physics.Therefore,we believe that the research on the history of physics is worth mentioning the history of physics related to molecular beam method.After determining the material selection of physics history,we collect the original literature about molecular beam method in many aspects and all directions,and collate and analyze the collected data.This paper attempts to sort out the history of molecular beam method and the experiment of Nobel Prize in Physics based on molecular beam method.Taking the molecular beam experiments carried out by the important figures Dunoyer,Stern,Rabi and Ramsey as the main research objects,this paper discusses the practical scheme of introducing the history of physics related to molecular beam method into college physics teaching,hoping to provide some reference for college physics teaching.The paper is mainly composed of four chapters.Chapter one: introduction.This paper briefly combs the curriculum and teaching theory(physics)major main research content-physical teaching process.Based on the teaching methods in the process of physics teaching and the contents of college physics teaching,it is pointed out that the introduction of physics history may become a feasible teaching means to improve the quality of college physics teaching.Chapter two: the development history of molecular beam method.In the history of physics,we choose the molecular beam method as the main research object.Based on the history of molecular beam method,the development of important node scientists Dunoyer,Stern,Rabi,Ramsey and other characters as the starting point,the experiments and academic achievements of major scientists are combed in detail.It provides a lot of material for the introduction of college physics teaching in the history of physics related to molecular beam method.Chapter three: A Nobel Prize experiment based on the molecular beam method.The experiments winning the Nobel Prize based on molecular beam method are reviewed,and we focus on several of these important experiments-Lamb shift,the anomalous magnetic moment of electrons,atomic clock,nuclear magnetic resonance.This content is added to the introduction of related physics history of molecular beam method.Chapter four:The history of physics related to molecular beam method is introduced into the teaching of physics in universities.Firstly,the possibility of introducing the history of physics related to molecular beam method into college physics teaching is discussed,and then the concrete scheme of combining the history of molecular beam method with university physics course is designed(Stern experiment,Stern-Gerlach experiment,time).The application of molecular beam method in other courses(university physics experiment,atomic physics,history of physics)is briefly mentioned.Chapter five: conclusion and enlightenment.We point out that the introduction of molecular beam method related physics history into college physics teaching will broaden the scope of students' knowledge and stimulate students' interest,which may help to improve the overall teaching quality of college physics.
