The Contextual Analysis And Significance Of Symmetry In Physics

Symmetric phenomena is common in nature world, and have raised attention ever since the early stage of human society, according to the record of ancient Greek, when symmetry was applied to various aspects of social life, o as to form an artistic attitude-briefness and similarity. In 20th century, systematic research on symmetric phenomena had a further development, especially in physics. On the basis of symmetric phenomena research, we can summarize, develop and form symmetric theory. In this paper, we will finish some research about symmetric phenomena in physics, confirm object which can finish symmetric transition, confirm words which can express symmetric transition, confirm logic structure which can conclude symmetric transition, so as to grasp the essential characteristic of symmetric transition. Then I will analysis some types of formal space about symmetric transition, get the recognizing approaches of symmetric relation. We analysis symmetric phenomena which appear in physics’ branch, explain its physical meaning. Next I will grasp the formal characteristic and syntax structure, enhance the nature of axiom and acceptability of symmetry theory, enrich the meaning of contextual analysis about scientific theory.There are four parts in this paper, preface, chap 1-2, chap3-10 and conclusion.In preface, it is the background about this paper, including the research situation about symmetric phenomena at home and abroad, the application of contextual analysis, and so on. Next I will introduce the aims and meanings of contextual analysis about symmetric phenomena. On purposes, the train of thought will be developed. Finally, I will summarize the exploring spots and insufficient lies, so as to point out what to do next.Part Ⅱ concludes chap 1 and 2, the foundation of ontology and approach of epistemology about symmetric phenomena will be revealed in this part. According to cognitive sequence, in chap 1, I will introduce the recognizing approach about symmetric phenomena. In the beginning, symmetric conception which was found in many types of space will be analyzed, we can achieve the transition from the knowing of symmetric phenomena to the grasping of symmetric relation, we can get the symmetric theory after that summary. As an important analytic approach in philosophy of science, contextual analysis should make a contribution to the research of symmetry theory, it can achieve the analysis of symmetry theory and expound its meaning in form level, semantic level and pragmatics level. In chap 2,1 will analyze the foundation of ontology about symmetric transition, so as to present the logic structure and its characteristic of symmetric relation. There are two parts part one, analysis and construct symmetric relational conception, including symmetric objects, words and concepts, moreover, the definition of intension and extension about symmetric concepts. In the other part, Ⅰ will analyze the worlds and proposition about symmetry, in order to achieve the transition from usual language to scientific language and scientific proposition.Part Ⅲ concludes chap 3 to chap 10, it is the main part of this paper. In this part, I will introduce the contextual analysis and significance of symmetric phenomena. They are typical and comprehensive, but they are not the all branches of physics. They are classical physics, solid-state physics, thermal physics, electricity and magnetism, atomic physics, quantum mechanics, quantum field and particle physics. According the sequence of chaps, we will find that, the objects which can achieve symmetric transitions gradually change from macroscopic object to microcosmic object, from specific object to abstract object. Symmetric phenomena translated from easily observe to hardly observe. Scientific research approach translates from macroscopic analysis to microcosmic analysis. As a compositive research approach, in the way of recognition about symmetric transition, contextual analysis can ignore the carrier of symmetric transition, it can achieve the explanation about the meaning of symmetric transition, it can analysis the structure and its characteristic of symmetric transition, it can grasp the syntactic and its characteristic of symmetric transition, then symmetric theory as a universal rule can be applied to other branch of physics.Part Ⅳ is conclusion. I will expound the meaning of contextual analysis about scientific theory. Scientific thought can be expressed by language. There are two forms of language, one is scientific language, the other is formal language, both of which have epistemological background. Sentence is the basis of scientific theory’s states, scientific words can describe scientific phenomena exactly, formal words can describe the logical relation between objects. Form chap 3 to chap 10,1 will analysis symmetric phenomena in contextual analysis approach, respectively in formal, semantic and pragmatics point of view. In the end of this paper, I will expound the meaning of formal analysis’meaning, semantic analysis’meaning and pragmatics analysis’meaning.
