Rabi's Inheritances On Molecular Beam Method And An Overview Of His Physical Achievements

Based on the theory of constructivism,this paper discussed the integration of physics history research and university physics experiment teaching.History of physics Introduces into college physics teaching which is an important direction for the specialty of curriculum and teaching theory,and the teaching of college physics experiment is an important content of college physics teaching.In the new era,the introduction of the history of physics into the university physics experiment teaching is endowed with a new significance of The Times,and it is particularly necessary to think about the introduction of the history of physics into the university physics experiment teaching.In the history of physics,there are many classical physics experiments,which design ideas,methods,technologies and devices are concentrated display of scientific-thinking and physical-thinking.Systematic in depth research on a typical experiment or experimental methods,from the current domestic history of physics research results,or relatively inadequate.Based on this situation,the current history of physics research service university physics experiment teaching is limited,and the main content of this paper is based on the theory of constructivism concrete history of physics experiment research to try to answer this question.The first chapter is introduction,mainly discusses the research background,research status at home and abroad,research content,research ideas and methods,research significance and innovation.The thesis mainly includes two parts.The first part takes the typical event of Rabi and his physical achievements as the object and makes an in-depth study of the history of physics.The second part,taking the opportunity of "Chinese Students' Key Competencies" in the new era and combining the research results and inspirations of the history of physics,reflects on the introduction of the history of physics into the university physics experiment teaching,and discusses the methods,principles and existing problems of the integration of the history of physics research and the university physics experiment teaching through practice.The second chapter is molecular beam magnetic resonance experiments.Based on the history of physics,molecular beam magnetic resonance experiment,the representative work of Rabi were discussed in detail,from the background,principle,device,process and result.Stern and Gorter have influenced on Rabi was briefly discussed.the experimental principle and measurement principle of molecular beam magnetic resonance method were introduced.The Rabi overcame two problems from the experimental device,which reflected Rabi's contribution to the invention of molecular beam magnetic resonance method,highlighted Rabi's contribution to the invention of molecular beam magnetic resonance method,and combed the history of the Rabi's molecular beam magnetic resonance experiment in detail.The third chapter systematically discusses the development history of molecular beam method and the research of Rabi's physical achievements.Starting from the external history of physics and taking the molecular beam magnetic resonance experiment as the axis,this paper summarizes the development history of the Rabi and his physical achievements.The Rabi studied under Stern,who was an important influence on his academic career.From 1929 year to 1939 year,Rabi spent ten years to invent the molecular beam magnetic resonance method,which made an important contribution to the development of molecular beam method and established its important position in physics.In addition,the Rabi's contributions in science education and international scientific collaboration are reviewed,and the physical achievements of Rabi are summarized comprehensively.The fourth chapter is based on the research of Rabi's physics achievements to discuss university physics experiment teaching.Based on the study of the history of physics,this paper discusses the methods,principles and existing problems of introducing the history of physics into the teaching of physics experiment under the Key Competencies.The introduction of the history of physics into college physics experiment teaching not only has a positive impact on the cultivation of students' Key Competencies,but also provides a practical path for the course ideology and politics of physics major,but the specific practices still need to be improved constantly.The fifth chapter is conclusion,reflection and inspiration.It mainly explains the research results,existing problems and the enlightenment obtained through the research.The idea of the integration of physics history and physics experiment teaching is a widely accepted teaching reform method,but how to integrate naturally and effectively is not a simple work,and there are still many problems to be overcomed.From the perspective of teachers and prospective teachers,it is necessary to do some studies on the history of physics,which is an important way to internalize knowledge,cultivate physical thoughts and enhance scientific literacy.
